Description

  The present invention relates to a slot machine, and in particular, when it is determined that the derivation of a predetermined special display result is permitted, the advantageous display result is derived according to the operation procedure of the stop operation means, whereby the gaming state is brought into an advantageous state. It relates to a slot machine that controls

  A slot machine generally includes a variable display device having a plurality of (usually three) reels having a plurality of types of symbols as identification information drawn on the outer periphery, and each reel has a start lever by a player. Rotation is started by operating, and when the player operates a stop button provided corresponding to each reel, the rotation is stopped within a range of a predetermined maximum delay time from the operation timing. . Then, a prize is generated according to the display mode derived when the rotation of all the reels is stopped.

  When a symbol of bonus combination such as a regular bonus or a big bonus is derived in the winning display mode, the game state is controlled to a bonus game state that is more advantageous to the player than the normal game state. By controlling the game state different from the normal game state such as this bonus, the game is sharpened and the interest of the game is improved. Here, in order for a winning combination including a bonus combination to occur, generally, if an internal lottery performed in advance (usually when the start lever is operated) is won and the winning flag is not set. Don't be.

  In addition to the normal game state and the bonus game state, the specific game state is advantageous to the player. For example, there is an RT (Replay Time) that increases the probability of winning a replay in an internal lottery, which is much higher than the normal gaming state, and further improves the fun of gaming. Here, there is a slot machine that is in a probability variation state including other than replay, and is controlled to a probability variation state after the end of the big bonus by winning a predetermined lottery (see, for example, Patent Document 1).

  In addition, it is assumed that the RT symbol of “BAR-BAR-BAR” is derived to the variable display device as an opportunity to control the gaming state in RT, and this RT symbol is won in the RT lottery performed after the internal lottery. There is a slot machine that is derived on the condition that it exists (see, for example, Patent Document 2). In addition, there is a slot machine in which an RT symbol is derived when a small combination won in an internal lottery is missed by operating the stop button, and the gaming state is controlled to RT based on this (see Patent Document 3). ).

JP-A-6-335560 (paragraphs 0097, 0098, etc.) JP-A-2005-131323 (paragraphs 0034, 0040, 0041, etc.) JP 2006-102272 A (paragraph 0139 etc.)

  However, in the slot machine of Patent Document 1, whether or not to be controlled to the probability variation state is determined by the result of the lottery that is not related to the player's game operation. Sex did not occur. In addition, in the slot machines of Patent Documents 2 and 3, if the player wants to control the gaming state by RT when the result of the internal lottery is not known, the player performs a stop operation by an operation procedure that can derive the RT symbol. It was sufficient that there was no inconvenience. For this reason, the game is not strategic because it is controlled to RT by derivation of the RT symbol.

  An object of the present invention is to provide a slot machine capable of generating a strategy of a game with respect to whether or not to obtain an opportunity to control to an advantageous state, thereby improving the interest of the game.

To achieve the above object, a slot machine according to the present invention includes:
It is possible to start a game by setting a predetermined number of bets for one game using a game value (medal), and each of the variable display portions (reels 3L, 3C, 3R) is identified. A display result is derived to a variable display device (variable display device 2) that variably displays a plurality of possible types of identification information, whereby one game is completed, and a prize is awarded according to the display result derived to the variable display device. In the slot machine (slot machine 1) that can be generated,
Means for deciding whether or not to allow the derivation of a plurality of types of winning display results before the display result of the variable display device is derived for each game, wherein the first type of winning is displayed as the winning display result First determination means for performing a first determination to determine that the derivation of the display result is allowed, a second that is different from the first type of the winning display result and that the derivation of the first type of winning display result is permitted Pre-deciding means (step S102) including second deciding means for making a second decision that simultaneously decides in one game that the derivation of the type of winning display result is allowed ;
A plurality of stop operating means (stop buttons 12L, 12C, 12R) operated by the player to stop the variable display of the identification information in the plurality of variable display units, respectively;
Derivation control means (step S104) for causing the variable display device to derive a display result in accordance with a determination result of the prior determination means and an operation procedure of the plurality of stop operation means;
When an advantageous display result (RT symbol) that can be derived when the determination result of the prior determination means is the second determination (small combination 1 + small combination 2) is derived as the display result of the variable display device , Advantageous state control means (step S105) for controlling the gaming state to an advantageous state (RT) that is more advantageous to the player than the normal gaming state;
Advantageous information notification for notifying information that can be specified that the advantageous display result can be derived when the advantageous notification condition is satisfied when the determination result of the prior determination means is the second determination. Means (step S225),
The derivation control means includes
Advantageous display result deriving means for deriving the advantageous display result on condition that the plurality of stop operation means are operated in a predetermined order when the determination result of the prior determination means is the second determination. Operate the left stop button 12L for the third time, and operate the 5th or 6th symbol at the timing when it is positioned on the winning line where the “bell” is tempered first .
When the plurality of stop operation means are operated in an order other than the predetermined order even when the determination result of the prior determination means is the first determination or the second determination, First winning display result deriving means for deriving the first type of winning display result regardless of the operation timing of each stop operation means ,
The slot machine causes a predetermined disadvantage to the player when the stop operation means is operated in the predetermined order when information is not notified by the advantage information notification means (a left stop button (If 12L is operated first or second, the small part 1 that is not missed may be missed. Steps S241 to S243: When the navigation flag is not set, the AT flag is not set even if the RT symbol is derived)
It is characterized by that.

In the slot machine, the advantageous display result is derived as the display result of the variable display device, whereby the gaming state is controlled to the advantageous state advantageous to the player. The advantageous display result can be derived by operating the plurality of stop operation means in a predetermined order when the determination result of the prior determination means is the second determination . However, if the determination result of the prior determination means is not the second determination in the first place, the advantageous display result is not derived even if the plurality of stop operation means are operated in a predetermined order.

Here, when the advantageous notification condition is satisfied, the determination result of the predetermining means becomes the second determination, and when the advantageous display result can be derived, information that can specify that fact is notified by the advantageous information notification means. Therefore, if the player operates a plurality of stop operation means in a predetermined order according to the notified information, the variable display device can derive an advantageous display result, thereby controlling the gaming state to the advantageous state. It can be made to. On the other hand, when the advantageous notification condition is not satisfied, the player, but the determination result of pre-determining means do not know whether it is the second of the decision, if it is a second decision, even if such By performing a stop operation similar to the above, the advantageous display result can be derived, and the gaming state can be controlled to the advantageous state.

  Even when the advantageous notification condition is not satisfied, there is a chance that the gaming state is controlled to the advantageous state by operating the plurality of stop operation means in a predetermined order. Doing so will cause certain disadvantages. As a result, there is a strategy in the game, such as whether to try to control to the advantageous state while accepting that there is a disadvantage, or to avoid the disadvantage without trying to control to the advantageous state. Can improve the interest of

On the other hand, when the advantageous notification condition is satisfied, information that can specify that the advantageous display result can be derived is notified if the determination result of the predetermination means is the second determination. Assuming that the player can perform an appropriate stop operation according to the above, it is possible to control the gaming state to the advantageous state, so the specification of controlling the gaming state to the advantageous state by deriving the advantageous display result is useless. It will not become.

  The predetermined order as the operation order of the plurality of stop operation means is preferably set to an operation order different from an operation order (so-called forward pressing) generally performed except for a special case by the player. In this case, it is because a predetermined disadvantage does not occur unintentionally while the player performs a stop operation as usual.

The advantageous display result may be a specific type of winning display result among a plurality of types of winning display results. Moreover, the advantageous display result may be a display result that is different from a winning display result. Here, the derivation control means may derive the advantageous display result as a display result different from the winning display result when the determination result of the prior determination means is the second determination. .

In the latter case, the derivation control unit stops displaying the variation of the identification information on the plurality of variable display units within a predetermined maximum delay time (190 milliseconds) from the operation of the corresponding stop operation unit. The plurality of stop operation means are operated in a predetermined order, and the predetermined stop operation means among the plurality of stop operation means is operated at a predetermined timing. An advantageous display result can be derived.

Further, the predetermined disadvantage occurs regardless of whether or not the determination result of the prior determination means is the second determination , provided that the advantage notification condition is not satisfied. Can be. Alternatively, when the advantageous notification condition is not satisfied, the predetermined disadvantage may occur on the condition that the determination result of the prior determination unit is not the second determination .

Further, it may be determined whether or not the advantageous notification condition is satisfied before a certain period. For example, it may be determined whether or not an advantageous notification condition is established for the entire normal gaming state by lottery in a predetermined gaming state before being controlled to the normal gaming state. Moreover, it is good also as what determines whether the said advantageous alerting | reporting conditions are satisfied by the lottery performed whenever the determination result of the said prior determination means becomes a 2nd determination .

Further, the information that can specify that the advantageous display result notified by the advantageous information notification means can be derived is not only information that directly indicates that the advantageous display result can be derived, but also indirectly. It may be the information shown. For example, when the determination result of the prior determination means is the second determination, the advantageous display result can be derived by missing both the first type winning display result and the second type winning display result. if made possible, or as an indication of the information indicating that the second determination is performed. Or it is good also as what alert | reports the identification information which pushes in order to derive | lead-out the said advantageous display result, or alert | reports identification information other than the identification information which pushes. Further, the notification mode may be any as long as it can be specified that the player can derive the advantageous display result, and may be based on an image, sound, light, or an accessory.

  Further, the disadvantages caused by one operation of the stop operation means in a predetermined order are made smaller than the profits obtained by the player in the entire advantageous state, and a plurality of stop operation means are preliminarily determined in all games. It is preferable that the expected value of the total disadvantage caused when operating in the above order is larger than the profit that the player can obtain in the entire advantageous state. This is because a strategy for selecting high risk / high return or low risk / low return arises.

In the above slot machine,
The pre-determining means includes specific determining means (FIG. 16 (b): small combination 1, small combination 1 + small combination 2) for determining whether or not derivation of a predetermined specific display result (small combination 1) is permitted. May be included. In this case,
The derivation control unit is a control that does not derive the specific display result when the plurality of stop operation units are operated in the predetermined order when it is determined that the derivation of the specific display result is permitted. Specific non-derivation control means (operating at the timing when the left stop button 12L is operated third and the symbol of No. 5 or No. 6 is positioned on the winning line where the “bell” is tempered first) May be included)
The predetermined disadvantage may be that the specific non-derivation control means does not cause the specific display result to be derived.

  In this case, if a plurality of stop operation means are operated in an operation procedure that can derive the advantageous display result, the specific display result is not derived even if it is determined that the derivation of the specific display result is permitted (the advantageous display result). Therefore, a predetermined disadvantage is caused by the control based on the gaming nature inherent in the slot machine by the derivation control means.

In the above slot machine,
The pre-determining means determines a small role determining means for determining that the derivation of a plurality of types of small role display results (three choice small combination 1 to three choice small combination 3) accompanied by the addition of the gaming value is permitted (FIG. 16 (b): 3 choices 1, 3 choices 2, 3 choices 3)
The derivation control means includes
When it is determined by the pre-decision means that derivation of the first type of small combination display result among the plurality of types of small combination display results is permitted, and the stop operation procedure is operated in the first small combination procedure The first type of small combination display result is derived, and when the stop operation means is operated in a procedure other than the first small combination procedure, a display result other than the first type of small combination display result is derived. Small winning combination display result deriving means (for example, the three-choice small winning combination 1 is to operate the stop button 12R at the timing when the symbols No. 12 to No. 18 are located in the lower row of the right reel 3R)
It is determined by the pre-determining means that derivation of the second type of small combination display result among the plurality of types of small combination display results is permitted, and the second small combination procedure is different from the first small combination procedure. When the stop operation means is operated, the second type of small combination display result is derived, and when the stop operation means is operated in a procedure other than the second small combination procedure, the second type of small combination display result. Second small combination display result deriving means for deriving display results other than (for example, the three-choice small combination 2 operates the stop button 12R at the timing when the symbols 5 to 11 are positioned on the lower stage of the right reel 3R. May also include a condition for winning a prize). In this case,
When the slot machine has determined that the derivation of any kind of small combination display result is permitted by the small combination determination means in the advantageous state, the slot machine is for deriving the type of small combination display result. Derivation operation procedure notifying means (step S220) for notifying the player of information that can specify the derivation operation procedure is further provided,
The predetermined disadvantage may be that information that can specify the derivation operation procedure is not notified to the derivation operation procedure notification means (steps S241 to S243: RT symbols are derived when the navigation flag is not set). Even if the AT flag is not set).

  In this case, when the advantageous notification condition is not satisfied, it is determined that the derivation of the advantageous display result is permitted, and the advantageous display result is derived by operating the plurality of stop operation means in a predetermined order. Even in this advantageous state, the derivation operation procedure is not notified, and the profit is smaller than the advantageous state based on the derivation of the advantageous display result when the advantageous notification condition is satisfied. This reduces the effectiveness of operating the plurality of stop operation means in a predetermined order when the advantageous notification condition is not satisfied, so that the player recognizes that the advantageous notification condition is established more specially. It becomes possible.

In the above slot machine,
The pre-determining means includes a special display result (big bonus (1), big bonus (2), regular bonus) with a transition to a special gaming state (big bonus, regular bonus) advantageous to a player different from the advantageous state. Special deciding means (FIG. 16 (b): big bonus (1), big bonus (2), regular bonus) for deciding whether or not to allow derivation of (bonus) may be included. In this case,
The slot machine further includes special gaming state control means (step S105) for controlling the gaming state to the special gaming state when the special display result is derived as the display result of the variable display device.
Even if it is determined that the derivation of the special display result is permitted, the advantageous state control means does not end the advantageous state, and the predetermined number of games until the special display result is derived or from the start of the advantageous state. Until the game is completed, the gaming state can be controlled to the above-mentioned advantageous state (RT is not ended only by winning the big bonus (1), the big bonus (2), the regular bonus, the big bonus ( 1) End when Big Bonus (2), Regular Bonus is won or when 200 games are consumed).

  In this case, the advantageous state continues for a predetermined number of games unless a special display result is derived and controlled to the special game state. In other words, the player does not lose the profit of the advantageous state of the duration of the predetermined number of games because the advantageous state does not end only when it is determined by the predetermining means that the derivation of the special display result is permitted. That's it.

The slot machine is
Special gaming state control for controlling the gaming state to a special gaming state (big bonus, regular bonus) advantageous to a player different from the advantageous state until a predetermined end condition is satisfied when a predetermined special transition condition is satisfied Means (step S105);
Effect selection means (step S207) for selecting the type of effect to be executed in the special game state in accordance with an instruction from the player;
Selection effect execution means (step S209) for executing the kind of effect selected by the effect selection means when controlled to the special game state;
Lottery means (steps S229, S233, S236 (YES)) for performing lotteries with different winning conditions according to the type of the effect selected by the effect selection means when controlled to the special game state;
Advantageous notification condition establishing means (step S231 → S256, step S235 → S215, step S237 → S248) for establishing the advantageous notification condition after the special gaming state is ended when the lottery means is selected.
When the advantageous notification condition is established by the advantageous notification condition establishment means, a condition establishment notification that informs that the advantageous notification condition is established in a manner corresponding to the type of the effect selected by the effect selection means. Means (steps S214, S247, S255) may be further provided.

  Here, since the player can select the type of effect executed in the special game state by his / her own operation, the interest of the effect executed in the special game state is improved, and it is interesting to select the type of effect. Will increase. In addition, when controlled in the special gaming state, a lottery is performed under the winning conditions according to the type of performance selected by the player, and an advantageous notification condition is established after the special gaming state ends by winning the lottery. Then, the advantage information notification means notifies that the advantage notification condition is satisfied.

  Here, when the advantageous notification condition is established, the fact is notified to the player by the condition establishment notification means, but the notification mode also varies depending on the type of effect selected by the player through his / her own operation. Therefore, the interest in selecting the type of production is further increased. Furthermore, whether or not to notify that the advantageous notification condition has been established after the end of the special gaming state is drawn according to different winning conditions depending on the type of performance selected by the player's own operation, This will further increase the fun of the selection. In addition, the selection of the type of performance in the special game state by the player also affects the progress of the game itself, that is, the establishment of the advantageous notification condition, that is, the notification of information that can be specified that the advantageous display result can be derived. Therefore, it is possible to increase the player's sense of intervention in the game, thereby improving the interest of the game.

  FIG. 4 is a schematic diagram showing a wiring connection state between the game control board 101 and the game electronic components connected to the game control board 101. FIG. 4 shows a single BET switch 45, a MAXBET switch 46, which is operated when setting a bet number among various electronic components such as various switches and sensors connected to the game control board 101, and when starting a game. A start switch 41 that is operated, stop switches 42L, 42C, and 42R that are operated when the rotation of the reels 3L, 3C, and 3R is stopped, a inserted medal sensor 44 that detects a medal inserted to set the bet number, Reel motors 3ML, 3MC, 3MR for rotating the reels 3L, 3C, 3R, reel sensors 3SL, 3SC, 3SR for detecting the rotation of the reels 3L, 3C, 3R, and detection of medals to be paid out when a winning occurs The payout sensor 81 and the effect control board 102 are shown, and other switches, sensors, etc. are not shown. .

  The game electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 3ML, 3MC, 3MR, 82, 81 except for the effect control board 102 are used for playing signals related to the progress of the game. It is an electronic component that inputs and outputs to the control board 101. The signal related to the progress of the game is, for example, an operation for setting the number of bets to make the game startable, an operation for starting the game, or an operation for deriving the display results of the reels 3L, 3C, 3R. Such as signals output to the game control board 101 in accordance with the progress operation of the game, detection of inserted medals, reference position of the reel, detection of payout medals, etc. In order to drive the signal input to the game control board 101, the drive signal for driving the reels 3L, 3C, 3R in response to the detection of the start operation, and the hopper 80 for paying out medals when a winning is generated. And a signal output from the game control board 101 in accordance with the progress of the game and input to the game electronic component.

  These gaming electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 3ML, 3MC, 3MR, 82, 81 are sent to the game control board 101 as the game progresses. And a second electronic component to which a signal from the game control board 101 is input as the game progresses.

  Specifically, the single bet switch 45, the MAXBET switch 46, which are operated when setting the bet number, and the inserted medal sensor 44 which detects a medal inserted to set the bet number, It is a first electronic component that outputs a BET signal to the game control board 101 based on the detection. Since the game control unit 110 performs a bet number setting process based on reception of the BET signal, the bet number cannot be set without these electronic components. That is, since the game cannot be started unless the bet number is set, the one-sheet BET switch 45, the MAXBET switch 46, and the inserted medal sensor 44 are game electronic components necessary for the progress of the game.

  A start switch 41 that detects an operation for starting a game is a first electronic component that outputs a start signal to the game control board 101 based on the detection of the operation. The game control unit 110 performs a process of starting a game (reel rotation process or the like) based on the reception of the start signal. Therefore, the game cannot be started without this electronic component. That is, the start switch 41 is a game electronic component necessary for the progress of the game.

  Stop switches 42L, 42C, and 42R that detect operations for deriving the display results of the reels 3L, 3C, and 3R are first electronic components that output a stop signal to the game control board 101 based on the detection of the operations. is there. Since the game control unit 110 performs a process of deriving a display result by stopping the rotation of the corresponding reels 3L, 3C, and 3R based on the reception of the stop signal, the reels 3L, 3C, and 3R do not have this electronic component. The display result of cannot be derived. That is, the stop switches 42L, 42C, and 42R are game electronic components necessary for the progress of the game.

  The reel sensors 3SL, 3SC, and 3SR that detect the rotation of the reels 3L, 3C, and 3R are first electronic components that output a detection signal for the reference position of the reel to the game control board 101. The game control unit 110 does not have this electronic component because it performs processing to stop the rotation by grasping the positions of the symbols of the corresponding reels 3L, 3C, and 3R based on reception of the detection signal of the reference position of the reels. In addition, derivation of display results of each reel 3L, 3C, 3R, determination of winning, etc. cannot be performed. That is, the reel sensors 3SL, 3SC, 3SR are game electronic components necessary for the progress of the game.

  A payout sensor 81 that detects medals to be paid out when a winning is generated is a first electronic component that outputs a medal payout signal to the game control board 101 based on the detection of the medals. The game control unit 110 performs payout processing for paying out the number of medals corresponding to the generated winning based on the reception of the payout medal detection signal, and therefore, the number of medals corresponding to the generated winning without this electronic component. Cannot be paid out. That is, the payout sensor 81 is a game electronic component necessary for the progress of the game.

  The reel motors 3ML, 3MC, and 3MR that rotate the reels 3L, 3C, and 3R are second electronic components to which a drive signal output from the game control board 101 is input. The reel motors 3ML, 3MC, and 3MR rotate the reels 3L, 3C, and 3R based on the input of the drive signal output from the game control board 101, and start the symbol variation display. Even if the reels 3L, 3C, and 3R are not actually rotated based on the above, the game control unit 110 receives the signals from the reel sensors 3SL, 3SC, and 3SR after outputting the reel drive signal. The game can be controlled to proceed as the reel rotates. However, the timing at which signals are input to the game control board 101 from the reel sensors 3SL, 3SC, and 3SR is an error unless the reel drive signal is output. In order to measure the output timing of a signal based on the detection of rotation, a reel drive signal is required. That is, the reel motors 3ML, 3MC, and 3MR are game electronic components necessary for the progress of the game.

  The hopper motor 82 that drives the hopper tank that pays out medals is a second electronic component that receives a drive signal output from the game control board 101 in response to the occurrence of a prize. The hopper motor 82 drives the hopper 80 based on the input of the drive signal output from the game control board 101 to pay out medals, but does not actually drive the hopper 80 based on the signal input. Even if the game control unit 110 outputs the drive signal of the hopper 80, the game control unit 110 can control to advance the game as a medal is paid out by inputting the signal from the payout sensor 81. it can. However, since the timing at which a signal is input from the payout sensor 81 to the game control board 101 is an error unless the drive signal of the hopper 80 is output, the payout medal is detected when the game is advanced by a driving tool. In order to measure the output timing of the signal based on this, a driving signal for the hopper tank is required. That is, the hopper motor 82 is a game electronic component necessary for the progress of the game.

  Also, these gaming electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 3ML, 3MC, 3MR, 82, 81 are basically common to multiple models. Since it is an electronic component to be used and there is little opportunity to remove and replace it from the main body unless a failure or the like occurs, it is fixed at a predetermined position of the main body of the slot machine. On the other hand, the game control board 101, the effect control board 102, and the like need to be replaced when changing the model, and are removed from the main body at that time.

  That is, when removing the game control board 101, the connection with the game electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 3ML, 3MC, 3MR, 82, 81 is released. Because it is necessary, gaming electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 3ML, 3MC, 3MR, 82, 81 and game control board 101 are relay boards 100, 103 , 106, 107, and the boards and the board and the game electronic component are connected via a cable.

  In this embodiment, each electronic component 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 3ML, 3MC, 3MR, 82, 81 is wired without a connector. Although extended, it may be connected to wiring via a connector.

  As described above, each board and each cable includes board-side connectors 620a to 620d, 621a to 621d, 622a to 622k, C1 and C4 provided on the board side, and cable-side connectors 610a to 610d provided on the cable side. Wiring is connected via a pair of connectors (male connector and female connector) consisting of 611a to 611d, 612a to 612k, C2, and C3, and the wiring connection is released by removing the cable side connector from the board side connector. Can be done. In particular, the game control board 101, the operation unit relay board 107, the reel relay board 103, the power supply board 100, and the effect control board 102 are attached to predetermined locations on the casing or front door of the slot machine 1, so that the board side Since the cable side connector can be easily removed from the connector, the game control board 101 and the effect control board 102 can be easily replaced.

  First, the first electronic component will be described in detail. One of the BET switch 45, the MAXBET switch 46 or the inserted medal sensor 44 and the cable control board 101 provided with the game control board 101 is driven into any connector. If the BET signal is illegally output from the driving tool to the game control board 101, the bet number may be set even though the bet number setting operation is not performed. When a connector of a driving tool is connected to one of the connectors of a cable provided between the start switch 41 and the game control board 101, and a start signal is illegally output from the driving tool to the game control board 101 There is a possibility that the game is started without performing the game start operation. The connector of the driving tool is connected to one of the connectors of the cable provided between the stop switches 42L, 42C, 42R and the game control board 101, and the stop signal is illegally transmitted from the driving tool to the game control board 101. If output, the rotation of the reel may be stopped without performing a stop operation.

  The connector of the driving tool is connected to one of the connectors of the cable provided between the reel sensors 3SL, 3SC, 3SR and the game control board 101, and the reel rotation signal is illegal from the driving tool to the game control board 101. Is output, the display results of the reels 3L, 3C, and 3R may be derived and winning decisions may be performed without rotating the reels. The connector of the driving tool is connected to one of the connectors of the cable provided between the payout sensor 81 and the game control board 101, and a medal payout signal is illegally output from the driving tool to the game control board 101. There is a possibility that the medals are counted without paying out medals.

  The second electronic component will be described in detail. The game control board 101 is released by disconnecting any one of the cable connectors provided between the reel motors 3ML, 3MC, and 3MR and the game control board 101. When the driving signal output from the game control board 101 can be acquired by the driving tool, the timing at which the driving signal of the reel is output from the game control board 101 can be specified on the driving tool side, so that the game control is originally performed from the reel sensors 3SL, 3SC, 3SR. There is a possibility that the reel rotation detection signal input to the substrate 101 may be output from the driving tool at an appropriate timing after the reel rotation.

  In addition, the drive signal output from the game control board 101 can be acquired by a driving tool or the like after the connection at any of the connectors of the cable provided between the hopper motor 82 and the game control board 101 is released. Then, since the timing at which the driving signal of the hopper tank is output from the game control board 101 can be specified on the driving instrument side, the payout medal detection signal originally input from the payout sensor 81 to the game control board 101 is sent from the driving instrument to the hopper tank. May be output at an appropriate timing after driving.

  As described above, the first electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 81 are output according to the progress of the game. When a signal to be played is output from the driving tool, the game control unit 110 can perform control to advance the game based on reception of the signal. On the other hand, when a signal that is output from the game control board 101 according to the progress of the game and is originally input to the second electronic components 3ML, 3MC, 3MR, 82 is input to the driving tool, When the game control unit 110 can specify the output timing of a signal output after driving the reel motors 3ML, 3MC, 3ML and the hopper motor 82, a new signal is input to the main control board 101 based on this. Since the game control unit 110 can perform control to advance the game based on the reception of the signal, there is a risk that an illegal act such as automatically progressing the game may be performed. In the slot machine 1 according to this embodiment, various measures are taken to prevent frauds due to the connection of a driving tool, as will be described later.

  Next, a configuration around the power source to the game control unit 110 in the game control board 101 will be described. FIG. 5 is a circuit diagram showing a backup power supply line for the game control unit 110.

The game control board 101 is supplied with a + 5V DC voltage generated by the voltage generation circuit of the power supply board 100. The + 5V DC voltage supplied from the power supply board 100 is supplied to the V _DD input terminal as a driving power supply for the game control unit 110, and also branches on the game control board 101 as shown in FIG. _BB ) DC voltage supply line is formed. The +5 V (V _BB ) DC voltage supply line is connected to the memory backup power input terminal V _BB of the game control unit 110 via the backflow prevention diode 312 and is connected to the ground on the power supply board 100 side. A capacitor (not shown) having a large capacity is provided between them. As a result, a DC voltage of +5 V (V _BB ) can be stored in the capacitor, and when the power supply to the slot machine 1 is interrupted, the voltage stored in the capacitor is stored in the RAM 112 in the game control unit 110. It can be supplied as a backup power source.

Further, the + 5V (V _BB ) DC voltage supply line is not directly connected to the memory backup power input terminal V _BB of the game control unit 110 on the game control board 101, but as shown in FIG. Via the cable 600a for wiring connection between the game control board 101 and the operation part relay board 107, the operation part relay board 107, the cable 601g for wiring connection between the operation part relay board 107 and the insertion medal sensor 44, and the insertion medal sensor 44 folded back, cable 601g, the operation unit relay board 107 is connected to the game control board 101 again via the cable 600a, and is connected to a memory backup power input terminal _{V BB} gaming controller 110. That is, when the power supply to the slot machine 1 is cut off, the voltage accumulated in the capacitor is changed from the game control board 101 to the cable 600a-operation part relay board 107-cable 601g-inserted medal sensor 44-cable 601g-operation part. After passing through the relay board 107-cable 600a, it is supplied to the game control unit 110, and the storage state of the RAM 112 in the game control unit 110 is maintained.

  Therefore, in a state where the power supply to the slot machine 1 is cut off, the connection between the board-side connector 620a of the game control board 101 and the cable-side connector 610a of the cable 600a, the cable-side connector 611a of the cable 600a and the operation unit relay board The connection line of the backup power supply is disconnected by releasing any of the connection between the board side connector 621a of the board 107 and the board side connector 622g of the operation unit relay board 107 and the cable side connector 612g of the cable 601g. As a result, the data in the RAM 112 of the game control unit 110 cannot be held and will be lost. That is, when even one connection between the game control board 101 and the inserted medal sensor 44 is released, the backup data held in the RAM 112 of the game control unit 110 is lost.

  In the slot machine 1 according to this embodiment, it is difficult to connect the driving tool by restricting the release of the connector connection between the game control board 101 and the game electronic component. Specifically, the connector connection between the game control board 101 and the inserted medal sensor 44, that is, the connection between the board side connector 620a of the game control board 101 and the cable side connector 610a of the cable 600a, the cable side connector 611a of the cable 600a. And the connection between the board-side connector 621a of the operation unit relay board 107 and the connection between the board-side connector 622g of the operation part relay board 107 and the cable-side connector 612g of the cable 601g are restricted from being released from each other. The connection between the board side connector 620a and the cable side connector 610a is restricted by the connector restricting member 500, the connection between the cable side connector 611a and the board side connector 621a, and the connection between the board side connector 622g and the cable side connector 612g.

In this state, the four sealing pieces 232 provided at one end of the upper case 203 and the fixing holes 256 of the fixing member 255 attached to the mounting base 250 are in corresponding positions, and in this state, any of the sealing pieces The sealing piece 232 and the fixing member 255 are fixed by screwing the aforementioned one-way screw into the corresponding fixing hole 256 from above the H.232.

  Then, by fixing the sealing piece 232 and the sealing piece fixing member 255, the movement of the substrate case 200 in the removal direction from the mounting base 250 at the end of the substrate case 200 on the sealing piece 232 side is restricted and the locking is performed. Since the horizontal movement of the substrate case 200 toward the sealing piece 232 side is also restricted by the pillar 253, the locking pieces 235 and 235 protruding to one end side of the substrate case 200 are removed from the locking holes 251 a and 251 a of the mounting base 250. It becomes impossible. Further, in this state, the screw holes 252 of the bottom plate 250a of the mounting base 250 are all covered with the substrate case 200, and access to the mounting screws 259 is impossible, and the mounting base 250 cannot be removed from the housing. Become. In this way, the substrate case 200 to which the attachment-side member 510 is attached is fixed to the housing via the attachment base 250, and the substrate case 200 is attached to the housing unless the sealing piece 232 or the fixing member 255 is broken. It will be in the state which cannot be removed from.

  When the board case 200 to which the attachment side member 510 is attached is fixed to the attachment base 250 (housing) so as not to be detached, as shown in FIG. 12A, the side piece 510d of the attachment side member 510 is provided. 510d abuts against the inner surfaces of the side walls 250b, 250c of the mounting base 250 and is held between them so that deformation of the both side pieces 510d, 510d of the mounting side member 510 outward is restricted. It becomes impossible to remove from 200.

  Next, as shown in FIG. 8, the cable 600a is connected to the board-side connector 620a of the game control board 101 exposed through the insertion hole 234 of the board case 200 and the notch 512 of the base piece 510a in the attachment-side member 510. After the cable-side connector 610a is connected, with the board-side connector 620a and the cable-side connector 610a connected, as shown in FIG. 11, the cover 521 of the connector cover 520 covers the upper side of the cable-side connector 610a. Then, the locking cylinder 522 of the connector cover 520 is fitted into the locking hole 513 a of the locking hole 513 in the attachment side member 510. As a result, the engaging portions 523 and 523 of the locking cylinder 522 abut against the inner periphery of the locking hole 513a and elastically deform inward. At this time, when the engaging portions 523 and 523 are positioned to cover the cable-side connector 610a with the covering portion 521, the shallow groove portions 514a and 514a among the engaging grooves 514 and 514 formed on the inner surface of the locking hole 513a. The locking cylinder 522 is further fitted, and the locking claws 523a and 523a at the tips of the engaging portions 523 and 523 reach the shallow groove portions 514a and 514a of the engaging grooves 514 and 514, As shown in FIG. 10A, the inward elastic deformation of the engaging portions 523 and 523 is released, and the locking claws 523a and 523a engage with the shallow groove portions 514a and 514a, respectively. The upward movement is restricted, and the side surface 521a of the covering portion 521 is brought into contact with the side surfaces of the board-side connector 620a and the cable-side connector 610a, so that the locking cylinder 522 is locked. By rotating against the part 513 is restricted, and ligated with the mounting member 510 and the connector cover 520, a state of integrated connector regulating member 500 is formed. In this state, since the engaging portions 523 and 523 are covered with the locking hole portion 513, it is impossible to elastically deform the engaging portions 523 and 523 inward from the outside, and the connector cover 520 or the attachment side member Unless 510 is broken, the connector cover 520 cannot be removed from the attachment side member 510.

  When the connector cover 520 is detachably attached to the attachment side member 510, a part of the upper surface of the cable side connector 610a is covered by the covering portion 521 as shown in FIGS. The movement of 610a in the pulling direction from the board side connector 620a is restricted, and the removal of the cable side connector 610a from the board side connector 620a is restricted.

  As described above, with the mounting side member 510 attached to the board case 200, the board case 200 is fixed to the housing, and then the cable side connector 610a is connected to the board side connector 620a. By attaching a part of 620a to the attachment side member 510 so as to cover from above, the cable side connector 610a cannot be removed from the board side connector 620a.

  Next, a situation when the connection between the cable side connector 610a and the board side connector 620a is released will be described.

  In order to release the connection between the cable side connector 610a and the board side connector 620a, the attachment side member 510 or the cable cover 520 is broken and the connector cover 520 is removed from the attachment side member 510, or the sealing piece 232 of the board case 200 is removed. Alternatively, it is necessary to break the fixing member 255, remove the board case 200 from the mounting base 250, and remove the mounting side member 510 with the connector cover 520 attached thereto from the board case 200.

  For example, when it is necessary to remove the cable-side connector 610a from the board-side connector 620a due to a failure of the cable 600a or the like, the latter method is used when the board case 200 is to be removed and replaced by the former method. Just remove it.

  First, when replacing the cable 600a, when it is necessary to remove the cable-side connector 610a from the board-side connector 620a, a method for removing the connector cover 520 from the attachment-side member 510 will be described. First, a connector such as a nipper is used. The connecting piece 522a that connects the covering portion 521 of the cover 520 and the locking cylinder 522 is broken. As a result, the covering portion 521 is separated and the locking cylinder 522 can be rotated with respect to the locking hole portion 513. In this state, by rotating the locking cylinder 522 counterclockwise as viewed from above, the engaging portions 523 and 523 move from the shallow groove portions 514a and 514a of the engaging grooves 514 and 514 to the positions of the deep groove portions 514b and 514b. Then, as shown in FIG. 10A, from the state where the locking claws 523a and 523a are engaged with the shallow groove portions 514a and 514a, as shown in FIG. 10B, the locking claws 523a and 523a The shallow groove portions 514a and 514a are disengaged. As a result, the locking cylinder 522 can be moved upward. As shown in FIG. 10C, when the locking cylinder 522 is pulled upward, the locking claws 523a and 523a are engaged with the deep grooves 514b and 514b. However, in this state, since the engaging portions 523 and 523 are exposed, the engaging portions 523 and 523 can be elastically deformed inward, and the engaging claws 523a can be elastically deformed inwardly. 523a and the deep groove portions 514b and 514b are disengaged, and the locking cylinder 522 can be detached from the attachment side member 510, whereby the connector cover 520 is completely separated from the attachment side member 510, and the connector cover 520 Since the restriction of the movement in the pulling direction of the cable side connector 610a due to is also released, the connection between the cable side connector 610a and the board side connector 620a is released. Door will be able to.

  When the connector cover 520 is removed from the attachment-side member 510, the covering portion 521 and the locking cylinder 522 are broken, and once broken, the original state is not restored. Therefore, the connection between the cable-side connector 610a and the board-side connector 620a There will be traces of unlocking.

  Next, when it is necessary to remove the cable side connector 610a from the board side connector 620a when replacing the whole board case 200, a method of removing the attachment side member 510 from the board case 200 together with the connector cover 520 will be described. The sealing piece 232 of the substrate case 200 fixed to the fixing member 255 is broken with a tool such as a nipper. As a result, the end of the substrate case 200 on the side of the sealing piece 232 can be moved away from the mounting base 250, so that the locking claw 253 a of the locking column 253 and the stepped portion 203 e of the substrate case 200 Release the engagement. Accordingly, the horizontal movement toward the sealing piece 232 is also possible, so that the locking pieces 235 and 235 of the board case 200 are removed from the locking holes 251a and 251a of the mounting base 250. Thereby, the board case 200 is detached from the attachment base 250, and the side pieces 510d and 510d of the attachment side member 510 can be deformed outwardly, without removing the connector cover 520 from the attachment side member 510. The attachment-side member 510 can be removed from the board case 200. With this, the attachment-side member 510 is removed from the board case 200 in a state of being integrated with the connector cover 520, whereby the cable-side connector 610a is removed by the connector cover 520. Since the restriction on the movement in the direction is also released, the connection between the cable side connector 610a and the board side connector 620a can be released.

  In order to remove the attachment side member 510 from the substrate case 200 also by this method, the sealing piece 232 of the substrate case 200 fixed to the fixing member 255 needs to be broken. Therefore, a trace of releasing the connection between the cable side connector 610a and the board side connector 620a remains.

  Further, according to this method, the sealing piece 232 of the board case 200 is broken and remains on the fixing member 255, but the attachment side member 510 can be removed from the board case 200 without removing the connector cover 520 from the attachment side member 510. Therefore, by attaching the attachment side member 510 in a state where the connector cover 520 is assembled to the new board case 200 in which the game control board 101 is accommodated for replacement, the cable side connector 610a and the board side in the new board case 200 are attached. The connection with the connector 620a is disabled, the new fixing member 255 is mounted on the mounting base 250, and the new board case 200 with the mounting side member 510 with the connector cover 520 assembled is mounted on the mounting base. 250 and the fixing member 255 and the sealing piece 232 are fixed to each other. Doing, becomes again impossible removably mounting member 510, when releasing the connection between the cable-side connector 610a and the substrate-side connector 620a is in a state leave its mark. That is, in such a case, the attachment side member 510 and the connector cover 520 can be reused.

  Next, the detailed structure of the connector restricting member 650 will be described.

  13 is an exploded perspective view showing the mounting table 660 and the cover member 680 constituting the connector restricting member 650. FIG. 14 is a perspective view showing a state in which the cover member 680 is assembled to the mounting table 660. FIG. 15A is a cross-sectional view taken along line EE in FIG. 14, and FIG. 15B is a cross-sectional view taken along line FF in FIG.

  As shown in FIGS. 13 and 14, the connector restricting member 650 includes a mounting table 660 on which the operation unit relay board 107 is mounted, and a cover member 680 that covers the mounting table 660 from above, and the mounting table 660. After accommodating the operation unit relay board 107, the cable side connectors 611a and 612g of the corresponding cables 600a and 601g are connected to the board side connectors 621a and 622g of the operation unit relay board 107, and then the cover member 680 is attached to the case. By attaching to the body 610, removal of the cable side connectors 611a and 612g from the board side connectors 621a and 622g is restricted.

  The mounting table 660 is made of a transparent synthetic resin and is formed in a substantially rectangular shape having a larger diameter than the operation unit relay board 107. As shown in FIG. 13, board-side connectors 621 a, 622 a, 622 b, 622 c, 622 d to 622 f, 622 g are mounted on the operation unit relay board 107, and both side surfaces on the long side of the mounting table 660 and the short side The board side connectors 622a, 622b, 622c, and 622d to 622f whose insertion holes open in the horizontal direction with respect to the mounting surface when the operation part relay board 107 is placed on one side surface on the side side. Each of the locking holes 661 having the locking holes 661b is provided via the connection piece 661a so as to protrude outward, avoiding the portion where the 622g is located. On the inner peripheral surface of the locking hole 661b, a pair of locking claws 661c and 661c facing the center are formed at positions facing each other across the center.

  The cover member 680 is made of a transparent synthetic resin and is formed in substantially the same shape as the mounting table 660. On one long side, a position corresponding to the board-side connector 621a of the operation unit relay board 107 is on the near side. A cover portion 681 that bulges toward the front side, and a cover portion 688 that bulges toward the near side at positions corresponding to the board-side connectors 622a and 622b of the working portion relay board 110 on the other long side. Cover portions 689 that bulge toward the front are formed at positions corresponding to 622c, 622g, and 622d to 622f, respectively.

  On the upper surface 681a of the cover part 681, a notch 681b for releasing the cable 600a connected to the board side connector 621a, which is narrower than the long side of the cable side connector 611a of the cable 600a, is formed on the outer side surface. Thereby, covering surfaces 681c and 681 are formed on both side ends of the upper surface 681a, respectively.

  The cover portion 688 has notches 682a for releasing the cables 612a and 612b connected to the board side connectors 622a and 622b, and the cover portion 689 has a cable 612c connected to the board side connector 622c. A notch 682b for releasing the cable, a notch 632c for releasing the cable 612g connected to the board-side connector 622g, and a notch 682d for releasing the cables 612d-f connected to the board-side connectors 622d-f are formed. Has been. In particular, the notch 682c for releasing the cable 612g connected to the board-side connector 622g is formed to be narrower than the length of the long side of the cable 601g, and both ends of the notch 682c are covered from the cover portion 689. Pieces 683 and 683 are respectively provided.

  Further, on both side surfaces on the long side and one side surface on the short side of the cover member 680, the locking holes are projected so as to protrude outward at positions corresponding to the locking holes 661 of the mounting table 660. A locking cylinder 684 having substantially the same diameter as the inner peripheral surface of 661b is provided via a connection piece 684a. Lock holes 684 are formed on the outer peripheral surface of the lock cylinder 684 at locations corresponding to the pair of lock claws 661c provided on the inner periphery of the lock hole 661b. Can be combined.

  Next, the mounting state of the mounting table 660 and the cover member 680 will be described. First, as shown in FIG. 13, the operation unit relay board 107 is mounted on the mounting table 660, and the board-side connectors 621a, 622a, 622b, and 622c. , 622d to 622f and 622g are connected to cable side connectors 611a, 612a, 612b, 612c, 612d to 612f and 612g, respectively. After connecting these cable side connectors to the board side connector, the cover member 680 is attached to the mounting table 660.

  Specifically, the locking cylinder 634 of the cover member 680 is fitted into the locking hole 661 b of the corresponding locking hole 661 of the mounting table 660. Then, by pushing the locking cylinder 634 into the locking hole 661b, the locking claw 661c in the locking hole 661b is engaged with the locking hole 684 of the locking cylinder 684. As a result, it becomes impossible to release the engagement between the locking claw 661c and the locking hole 684 from the outside, and as shown in FIG. 14, the mounting table 660 and the cover member 680 are connected to the locking hole. If the part 661 or the locking cylinder 634 is not broken, it is in a state where it is assembled so that it cannot be removed.

  When the mounting table 660 and the cover member 680 are assembled, as shown in FIG. 15A, the upper surfaces of both ends of the cable side connector 611a connected to the board side connector 621a of the operation unit relay board 107 are covered with the cover member. Covered by the covering portions 681c and 681c of 680, the movement of the cable side connector 611a in the pulling direction from the board side connector 621a is restricted, and the removal of the cable side connector 611a from the board side connector 621a is restricted. ing.

  When the mounting table 660 and the cover member 680 are assembled, as shown in FIG. 15B, the upper surfaces of both ends of the cable side connector 612g connected to the board side connector 622g of the operation unit relay board 107 are covered with the cover member. 680 is covered with the covering pieces 683 and 683 so that the movement of the cable-side connector 621g from the board-side connector 622g is restricted, and the removal of the cable-side connector 621g from the board-side connector 622g is restricted. ing.

  Next, the situation when the connection between the cable side connector 611a and the board side connector 621a and the connection between the cable side connector 621g and the board side connector 622g are released will be described.

  To release the connection between the cable-side connector 611a and the board-side connector 621a and the connection between the cable-side connector 621g and the board-side connector 622g, a connection piece 684a that connects the locking cylinder 684 of the cover member 680 with a tool such as a nipper is provided. Break. As a result, the main body of the cover member 680 and the locking cylinder 684 are separated, and the cover member 680 can be removed from the mounting table 660. By removing the cover member 680 from the mounting table 660, the covering portions 681c and 681c. The restriction on the movement of the cable-side connector 611a in the removal direction is released, and the restriction on the movement of the cable-side connector 621g in the removal direction by the covering pieces 683 and 683 is also released, so the cable-side connector 611a and the board-side connector 621a are released. And the connection between the cable-side connector 621g and the board-side connector 622g can be released.

  When the cover member 680 is removed from the mounting table 660, the main body of the cover member 680 and the locking cylinder 684 are broken. Once the cover member 680 is broken, the original state is not obtained and the separated locking cylinder 684 is removed from the mounting table 660. Therefore, there remains a trace that the connection between the cable-side connector 611a and the board-side connector 621a and the connection between the cable-side connector 621g and the board-side connector 622g are released. It will be.

  In the slot machine 1, a winning is awarded when the winning symbols are arranged on any winning line of the variable display device 2. The type of winning combination is determined according to the gaming state. As the gaming state, there are a big bonus and a regular bonus as a special gaming state in addition to the normal gaming state.

  The types of winning combinations can be broadly divided into special roles with transition to special gaming status (big bonus, regular bonus), small roles with payout of medals, and no need to set the number of bets. There is a re-player who can start the next game. FIG. 16A is a diagram for explaining the combination of the types of winning combinations in the slot machine 1 and the symbols in the variable display device 2.

  The regular bonus is awarded when a combination of “BAR-BAR-BAR” is aligned on any winning line in the normal gaming state or RT. When the regular bonus is won, the gaming state shifts from the normal gaming state to the regular bonus. The regular bonus ends when 12 games are consumed or when 8 games are won (any kind of combination is possible), whichever comes first. While the game state is in the regular bonus, the regular bonus medium flag is set in the RAM 112 (including the case where it is provided during the big bonus described below).

  The big bonus (1) is won when a combination of “red 7-red 7-red 7” is arranged in any winning line in the normal gaming state or RT. The big bonus (2) is won when a combination of “white 7-white 7-white 7” is arranged in any winning line in the normal gaming state or RT. When the big bonus (1) or the big bonus (2) is won, the gaming state shifts to the big bonus.

  In the big bonus, the regular bonus described above is repeatedly provided until the end. While the gaming state is the big bonus, the big bonus medium flag is set in the RAM 112. The big bonus ends when the number of medals paid out to the player exceeds 465. Here, since the maximum payout number per game is 15, the upper limit of the payout medal number in the big bonus is 480.

  Even if the regular bonus, the big bonus (1) or the big bonus (2) is won in the internal lottery to be described later, “red 7”, “white 7”, and “BAR” are 5 for all of the reels 3L, 3C, 3R. Since they are not arranged at intervals within a frame, depending on the operation procedure of the stop buttons 12L, 12C, and 12R, there are cases where these winning combinations are not won.

  The small role 1 wins when a combination of “bell-bell-bell” is arranged on any winning line in any game state, and 12 medals are paid out. The small role 2 wins when a combination of “red 7-bell-bell” is arranged on any winning line in any gaming state, and 12 medals are paid out. The small roles 1 and 2 may be won at the same time in one game, but the details of the stop control of the reels 3L, 3C, 3R when winning the small role 1 and / or the small role 2 are detailed. Will be described later.

  The three-choice winning combination 1 wins when a combination of “JAC-JAC-Red 7” is aligned on any winning line in any gaming state. The three-choice small role 2 wins when a combination of “JAC-JAC-White 7” is aligned on any winning line in any game state. The three-choice winning combination 3 wins when a combination of “JAC-JAC-BAR” is aligned on any winning line in any gaming state.

  Eight medals will be paid out when winning one of the three choice small roles 1-3. For the left and middle reels 3L and 3C, “JAC” is arranged at intervals of 5 frames or less, but for the right reel 3R, “red 7”, “white 7”, and “BAR” are 7 frames each other. One by one is arranged at intervals. That is, the three choice small combinations 1 to the three choice small combinations 3 are roles that cannot be aimed at each other at the same time.

  Replay is awarded when a combination of “JAC-JAC-JAC” is aligned on any winning line in the normal gaming state or RT. When a replay is won, there is no payout of medals, but the next game can be started without setting the number of bets again, so three medals corresponding to the number of bets 3 that are not required to be set in the next game are paid out. Is essentially the same. Since “JAC” is arranged at intervals of 5 frames or less for all of the reels 3L, 3C, and 3R, when the replay is won, the replay is performed regardless of the operation procedure of the stop buttons 12L, 12C, and 12R. Win a prize.

  Further, although not a winning combination, when the symbol combination of “white 7-bell-bell” is arranged on any winning line of the variable display device 2 in the normal gaming state, the RT symbol is derived. When the RT symbol is derived in the normal gaming state, the gaming state is controlled to RT only for the subsequent 200 games. Until 200 games have been consumed, RT cannot be terminated simply by winning the Big Bonus (1), Big Bonus (2) or Regular Bonus, but the Big Bonus (1), Big Bonus (2) or Regular Bonus If a prize is won, it will be terminated there.

  In the game state (including RT) other than the normal game state, even if the symbol combination “white 7-bell-bell” is aligned on the winning line of the variable display device 2, the game state is controlled to RT again. If the RT symbol is derived when the gaming state is RT, the current RT is continued as it is, and the RT continues until the remaining game of the current RT is consumed ( (However, until the Big Bonus (1), Big Bonus (2) or Regular Bonus is won)).

  When the gaming state is controlled to RT, as will be described later, the replay winning probability is higher than in the normal gaming state, and even if the AT is not added with an AT described later, the medal payout rate is greater than 1 ( That is, the number of medals to be paid out to the small combination won in the internal lottery is larger than the number of medals inserted for setting the bet number). On the other hand, the medal payout rate in the normal gaming state is smaller than 1, and the expected number of medals to be paid out when 200 games are played in the normal gaming state and RT (assuming that no AT is added). In the difference in value, a difference larger than 12 sheets paid out by one winning combination of the small combination 1 and the small combination 2 is generated.

  However, if the stop buttons 12L, 12C, and 12R are operated in all the games in the normal game state where the game navigation right is not granted in the operation procedure for deriving the RT symbol, Considering the probability of winning and the probability of winning simultaneously for small roles 1 and 2, before winning the RT symbol by winning both small roles 1 and 2 The expected value of the loss caused by missing the winning combination 1 is greater than the profit obtained by playing 200 games at RT.

  Hereinafter, the internal lottery will be described. The internal lottery is to determine whether or not the winning of each of the above combinations is permitted before the display result of the variable display device 2 is derived and displayed (actually, when the start lever 11 is operated). . In the internal lottery, a random number for internal lottery (an integer from 0 to 65535) is acquired from the random number generation circuit 115. Then, for each combination determined according to the gaming state, the acquired random number for internal lottery, the number of bets set by the player, and each combination determined according to the set value set by the setting switch 91 This is performed according to the number of judgment values. Winning in the internal lottery is exclusive.

  In the internal lottery, the number of judgment values registered for each game state and set value for each combination is sequentially added to the random number for internal lottery. It is judged that it was won. If the winning combination is determined, the winning flag of the combination is set in the RAM 112. The number of determination values is registered in the winning combination table according to gaming state in the ROM 113.

  FIG. 16B is a diagram showing a winning combination table by gaming state. The winning combination table by game state is stored in advance in the ROM 113, and is a table in which the number of determination values for each lottery target for each gaming state in the internal lottery is registered. Here, only a predetermined set value is shown, but a slightly different value is registered according to a difference in the set value. In the internal lottery, a plurality of combinations may be subject to lottery at the same time.

  According to the winning combination table by game state, in the internal lottery, the big bonus (1), big bonus (2), regular bonus, small part 1, small part 2, small part 1 + small part 2, three choice small part 1, three The selection small combination 2, the three selection small combination 3, and the number of replay determination values are sequentially acquired according to the gaming state. However, for the game state of the regular bonus (including the case where the bonus is provided during the big bonus), the big bonus (1), the big bonus (2), the regular bonus, the small role 1 + 2, and the replay judgment value number 0 Will not win these roles.

  In the normal gaming state or RT, since 0 is registered as the number of judgment values for the small combination 2, the small combination 2 is not won by itself. Of course, a small combination 1 + small combination 2 is determined as a lottery target combination, and when a small combination 1 + small combination 2 is won, two of a small combination 1 winning flag and a small combination 2 winning flag are set in the RAM 112.

  In addition, if the big bonus (1), big bonus (2), and regular bonus winnings are carried over from the previous game in the normal gaming state or RT, the big bonus (1), big bonus (2) No regular bonus will be won. On the other hand, in such a case, a small bonus 1, a small bonus 2, a three-choice small role 1, a three-choice small role 2, a three-choice small role 3, and a replay can be won. (1), Big Bonus (2), Regular Bonus Winning Flag, Winner of Minor 1, Minor 2, Three Choice Minor 1, Three Choice Minor 2, Three Choice Minor 3, or Replay Winning Flag Is set in the RAM 112.

  In addition, as the number of judgment values for each lottery target part in the regular bonus, the judgment value number d1 of the small part 1 is larger than the total of 3 g of the judgment value numbers of the three choice small part 1 to the three choice small part 3, The total 3 g of the judgment value numbers of the combination 1 to the triple choice small combination 3 is larger than the determination value number e of the small combination 2. In the normal gaming state or RT, the big bonus (1), big bonus (2), and regular bonus judgment value numbers are a, b, and c, respectively, but these may be the same value.

  In addition, the replay determination value number i2 in RT is larger than the replay determination value number i1 in the normal gaming state, whereas the replay winning probability in the normal gaming state is about 1 / 7.3. The replay winning probability in RT is about 1 / 1.4. Although the winning probabilities of other combinations other than replay are the same, the difference between the replay winning probabilities results in the relationship as described above between the normal gaming state and the medal payout rate in RT ( The relationship between the normal gaming state and the medal payout rate in RT is higher or lower than 1 is established at any setting value).

  Next, stop control of the reels 3L, 3C, 3R will be described. The reels 3L, 3C, and 3R constituting the variable display device 2 rotate on condition that the start lever 11 is operated and a predetermined time has passed since the start of rotation of the reels 3L, 3C, and 3R in the previous game. Be started. When the stop buttons 12L, 12C, and 12R are operated by the player, the corresponding reels 3L, 3C, and 3R are within the maximum stop delay time range of 190 milliseconds (4 frames pull-in range). In)).

  The reels 3L, 3C and 3R stop rotating so that the winning symbol set in the winning line is aligned on the winning line within the range of the maximum stop delay time of 190 milliseconds, and the maximum stop of 190 milliseconds Control is performed so that the symbols of the winning combinations for which the winning flag is not set within the delay time range are not aligned on the winning line, that is, the display result of the loss (including the RT symbol) is derived. If the winning flag is set for a different combination, the display result of the derived lose will be different even if the operation procedures (the order of operations and the respective operation timings) of the stop buttons 12L, 12C, and 12R are the same. Can be the result.

Here, when the winning flag for the small combination 1 is set (including the case where the winning flag for the small combination 2 is set), if the left stop button 12L is stopped first, the left reel As for 3L, since “bells” are arranged at intervals of 7 frames at the maximum, the “bell” can be stopped at any of the upper, middle and lower stages of the left reel 3L regardless of the operation timing. In this case, since the “bells” are arranged at intervals of 5 frames or less for the middle and right reels 3C and 3R, the operation procedure (operation order) of the stop buttons 12C and 12R corresponding to the remaining reels 3C and 3R. Regardless of the timing, the small role 1 can always be won .

  Further, when the winning flag for the small combination 1 is set (including the case where the winning flag for the small combination 2 is set), the middle stage of the reel 3C when the middle stop button 12C is operated first. When the right stop button 12R is operated for the first time, the “bell” is controlled to be stopped regardless of the respective stop timings. By operating the left stop button 12L for the second time, the “bell” can be stopped at the upper or lower stage of the reel 3L, so that “bell” is tempered on the winning line. Thereafter, when the right stop button 12R or the middle stop button 12C is operated third, “bells” are arranged at intervals of 5 frames or less for the middle and right reels 3C and 3R. You can always win.

  On the other hand, when the left stop button 12L is to be operated third (in addition, the case where the left stop button 12L is operated third is generally a reverse press of right → middle → left). Since there are many cases, the stop buttons 12L, 12C, and 12R are operated in the order of middle → right → left in some cases, it may be expressed as reverse pressing). For the middle and right reels 3C and 3R, Since the “bells” are arranged at intervals of 5 frames or less, the “bell” is always tempered before the left reel 3L is stopped.

  Here, if the left stop button 12L is operated at a timing when the 5th or 6th symbol of the left reel 3L is positioned on the winning line where the “bell” is tempered, then the “bell” ( Or the symbol “Red 7”) is placed at No. 11, so the left reel 3L is placed on the winning line where the “bell” is tempered during the maximum stop delay time of 190 milliseconds. “Bell” (or “Red 7”) cannot be pulled in.

  In this case, when only the winning flag of the small combination 1 is set, the sixth “BAR” is stopped for the left reel 3L on the winning line where “Bell” is tempered. On the other hand, if the winning flag for the small role 2 is set together with the winning flag for the small role 1, the 9th “white 7” is drawn for the left reel 3L on the winning line where the “bell” is tempered. Stop at. This is the only condition that can derive the RT symbol.

  As described above, in the slot machine 1 according to the present embodiment, as long as the stop button 12L is operated first or second in the normal gaming state (generally, the left, middle, and right pushes in this order) In many cases, it is not possible to miss this if the small part 1 is won (including the simultaneous winning with the small part 2). On the other hand, when the stop button 12L, 12C, 12R is operated in the operation procedure for deriving the RT symbol, the RT symbol can be derived when the small role 1 and the small role 2 are simultaneously elected, If only the small role 1 is elected, the small role 1 will be missed.

  In addition, when the big bonus (1), big bonus (2), regular bonus winning flag and replay winning flag are set in duplicate, the replay can be performed regardless of the operation procedure of the stop buttons 12L, 12C, 12R. Stop control is performed so that the symbols are preferentially aligned on the winning line. When the big bonus (1), big bonus (2), regular bonus winning flag and the winning flag of any kind of small role are overlapped, the big bonus (1), big bonus (2), If the stop control is performed so that the regular bonus symbol is preferentially aligned on the winning line, and the big bonus (1), big bonus (2), and regular bonus symbols cannot be aligned on the winning line, the winning flag Stop control is performed so as to align the symbols of the small role set with as much as possible on the winning line.

  In addition, when one of the three choice small roles 1 to three choice small roles 3 is won, according to the operation procedure of the stop buttons 12L, 12C, 12R, the winning one of these roles is won. Can be made. Here, the configuration symbols for the left and middle reels 3L and 3C are “JAC” which can be stopped at any position for any of the three alternative small combinations 1 to three. Whether or not the small combination 1 to the triple choice small combination 3 can be won depends on the operation timing of the right stop button 12R.

  For example, if the right stop button 12R is operated first or second, if the stop button 12R is operated at the timing when the symbols 12 to 18 are located in the lower stage of the right reel 3R, “Red 7” is stopped at the upper or lower stage of the reel 3R, but “white 7” and “BAR” cannot be stopped. If the stop button 12R is operated at the timing when the 5th to 11th symbols are positioned on the lower stage of the right reel 3R, “white 7” is stopped on the upper or lower stage of the right reel 3R. “Red 7” cannot be stopped. If the stop button 12R is operated at the timing when the symbols No. 19, No. 20, No. 0 to No. 4 are positioned in the lower stage of the right reel 3R, “BAR” is stopped in the upper stage or the lower stage of the right reel 3R. , “Red 7” and “White 7” cannot be stopped.

  When the right stop button 12R is operated third, “JAC” is selected for the left and middle reels 3L and 3C regardless of which of the three choice small combinations 1 to three choice small combinations 3. It is a temper on the winning line. In this case, if the stop button 12R is operated at a timing when the symbols 14 to 18 of the right reel 3R are positioned on the winning line where the “JAC” is tempered, “red 7” will be displayed on the winning line. Is stopped. If the stop button 12L is operated at the timing at which the 7th to 11th symbols are positioned on the winning line where the “JAC” symbol is placed in the lower stage of the right reel 3R, “White 7” will stop on the winning line. Is done. If the stop button 12R is operated at a timing when the symbols 0 to 4 of the left reel 3L are positioned on the winning line where the “JAC” is tempered, “BAR” is displayed at the upper or lower stage of the left reel 3L. Stopped.

  Note that the stop control of the reels 3L, 3C, and 3R described above is based on the stop operation position of the reels that have not yet stopped according to the gaming state and the setting status of the winning flag (and the symbols derived for the already stopped reels). A stop control table that defines the relationship between the stop position and the stop position is created in advance for unreacted reels, and when the stop buttons 12L, 12C, and 12R are operated, the stop control table created in advance is referred to and The rotation of the reel to be stopped is to be stopped. In the stop control table, the stop position is uniquely determined with respect to the stop operation position.

  On the game control board 101 side, the internal lottery is performed as described above, and the rotation of the reels 3L, 3C, 3R is stopped according to the result and the operation timing of the stop buttons 12L, 12C, 12R, and a prize is generated. It will be a thing. As a result of winning a prize, a medal is paid out or a game state is transferred as a payout. In this way, depending on the progress of the game on the game control board 101 side, an original effect is performed on the effect control board 102 side. Is called. In order to perform such an effect, the CPU 121 of the effect control board 102 must be able to recognize the progress of the game on the game control board 101 side. Is transmitted from the game control board 101 to the effect control board 102.

  The commands transmitted from the game control board 101 to the effect control board 102 include at least a BET command, a payment command, a winning status notification command, a reel rotation command, a reel stop command, a winning information command, and a game state command. . The commands transmitted from the game control board 101 to the effect control board 102 include other commands, but since they are not directly related to the present invention, a detailed description thereof is omitted.

  The BET command indicates the number of bets set up to now, and is transmitted whenever the number of bets set by the player's operation or the replay game is increased by one. In this embodiment, since the number of bets for playing one game is 3, the BET command is transmitted three times before the start of one game. The checkout command indicates the number of bets set for games that have not yet been started by operating the checkout button 16 (excluding those based on replay winnings) or credits have been settled. Alternatively, it is transmitted when a medal corresponding to the credit is paid out.

  The winning status notification command indicates the setting status of the winning flag in the RAM 112, and is transmitted when the start lever 11 is operated and an internal lottery is performed. The reel rotation command is transmitted when the reels 3L, 3C, 3R start to rotate. The reel stop command is transmitted when the stop buttons 12L, 12C, and 12R are operated. The winning information command indicates that the type of winning or the RT symbol generated according to the display result of the variable display device 2 is derived. The display result is derived to the variable display device 2 and the winning determination is performed. When sent. The gaming state command indicates a gaming state applied in the next game, and is transmitted at the end of one game.

  The CPU 121 of the effect control board 102 performs various effects based on the commands sent from the CPU 111 of the game control board 101 as described above. As such an effect, a game navigator for notifying that a small role 2 (simultaneous winning for small role 1) is won in the normal gaming state after the end of the big bonus, and a game navigator's right are informed to the player. There is a navigation notification that notifies the player of the fact to do so. The navigation notification is performed when the gaming state is in the big bonus, and is part of the production during the big bonus. In addition, there is a small role announcement that announces that when one of the three choice small combinations 1 to three choice small combinations 3 is won in RT after the RT symbol is derived according to the game navigation.

  In addition, game navigation is performed when a small role 1 + small role 2 is won when a game navigation right is granted in a game in a normal gaming state after the end of the big bonus. In the normal gaming state, when the small role 1 + small role 2 is won, the player reverse-presses the stop buttons 12L, 12C, 12R in order from right to left, and further, the left reel 3L, Nos. 5, 6 When the stop button 12L is operated at a timing when the symbol is positioned on the winning line where “Bell” is tentatively, the RT symbol is derived and the gaming state is controlled to RT (the gaming state is controlled by RT). Regardless of whether or not game navigation was performed).

  In a game in which game navigation is performed, it can be seen that a small role 1 + a small role 2 is surely won, so that the player can operate the stop buttons 12L, 12C, 12R in the above procedure. Assuming that, the gaming state can be shifted to RT by deriving the RT symbol. In addition, when an RT symbol is derived in a game in which a game navigation is performed, any of the three choice small roles 1 to three choice small roles 3 is selected in the RT controlled based on this. For example, the gaming state is controlled by the AT that is notified of the type.

  In games where no game navigation is performed, it is not known whether or not the small role 1 + small role 2 is won, but it happens when the player operates the stop buttons 12L, 12C, 12R in the above procedure. If the small combination 1 + small combination 2 is won, the gaming state can be shifted to RT by deriving the RT symbol.

  However, in games where no game navigation is performed, there are more cases where only the small role 1 is won and the small role 1 + small role 2 is not won, and the player presses the stop buttons 12L, 12C, 12R. If you press the stop button 12L at the timing when the stop button 12L is positioned on the winning line where the 5th or 6th symbol is “Bell”, This will be missed. Furthermore, even if a game where no game navigation is being performed happens to win a small role 1 + a small role 2 and the RT symbol can be derived, in the RT controlled based on this, the gaming state is set to AT. There is no control. Thus, if the stop button 12L, 12C, 12R is reversely operated in a game in which no game navigation is performed, the player will be disadvantaged.

  By the way, in the normal gaming state after the end of the big bonus, the decision as to whether or not to grant the game navigation right to the player is first made when the gaming state is in the big bonus, and the right of game navigation is granted. When it is decided to do so, a navigation notification is made as part of the production during the big bonus. There are three types of triggers for determining whether or not to grant game navigation rights in the big bonus game state, and which of these triggers is selected by the player at the start of the big bonus. Also, the mode of navigation notification differs depending on the player's selection.

  That is, before the first game of the big bonus is started, the three types of characters A, B, and C are switched and displayed for a certain period of time on the liquid crystal display 4, and the number of bets for the first game of the big bonus is displayed. The character switching display is stopped at the timing when the player performs the determining operation. The type of the character stopped here is an opportunity for determining whether or not to give the player the right of game navigation.

  When the character A is selected, if a winning combination with a winning probability of d2 / 65536 is won, a navigation lottery for determining whether or not to grant game navigation rights is performed. The winning probability of the navigation lottery here is approximately e / d2. In addition, even if the navigation lottery in this case is won, the navigation notification is not performed immediately, and the image of the character B is displayed on the liquid crystal display 4 as a part of the effect during the big bonus at the end of the big bonus. An announcement will be made.

  When the character B is selected, a navigation lottery that determines whether or not to grant the right of game navigator when winning one of the 3 choice small roles 1 to 3 choice 3 with a total winning probability of 3g / 65536 Is done. The winning probability of the navigation lottery here is approximately e / 3 g. In addition, in the case of winning the navigation lottery in this case, the bet set for the next game on the condition that one of the three choice small combinations 1 to three choice small combinations 3 is won here. When the number is confirmed, an image of the character B is displayed on the liquid crystal display 4 as a part of the effect during the big bonus, and the navigation notification is performed.

  When the character C is selected, if a winning combination with a winning probability of e / 65536 is won, it is determined that the right of game navigation is granted with a probability of 100% without passing through the navigation lottery. However, the navigation notification is not made only by winning the small role 2, and the character C is displayed on the liquid crystal display 4 as part of the big bonus medium effect when actually winning the small role 2 based on the winning of the small role 2. The image is displayed and the navigation notification is performed.

  When the gaming state is a regular bonus or a big bonus, the bonus medium music corresponding to the type of each bonus is continuously output from the speakers 7L, 7U, 7R. The bonus medium music output in the big bonus is a music according to the character type selected before the first game of the big bonus is started. Further, the regular bonus medium music is different from the bonus medium music in the big bonus.

  The bonus medium music is played at a predetermined volume level and is output from the speakers 7L, 7U, 7R while the gaming state is a regular bonus or a big bonus, but if the gaming operation is not continued for a predetermined period, Alternatively, the output is muted when a credit or an already set bet amount is settled. However, the mute is canceled if any operation for proceeding with the game is performed thereafter.

  It should be noted that the RAM 122 of the effect control board 102 is provided with an area for storing the winning situation indicated by the winning situation notification command received from the game control board 101. The big bonus (1), the big bonus (2) or the regular bonus is a role that is won until the prize is won, but the CPU 121 of the production control board 102 needs to determine that the bonus has been newly won. An area for storing the situation is provided for two games. In addition, the RAM 122 includes an area for storing the gaming state indicated by the gaming state command received from the gaming control board 101 and an area for storing the winning information by the winning information command received from the gaming control board 101. It has been.

  Further, the RAM 122 is provided with an area for setting a navigation flag indicating that a game navigation right is granted. In addition, even when the character A or character B is selected and the navigation lottery is won, or when the character C is selected and the small role 2 is won, the navigation notification is immediately performed. In these cases, it is determined that the right of game navigation has been granted, but the A notification flag, B notification flag, and C notification flag are set to indicate that the navigation notification has not yet been performed. An area for this purpose is also provided in the RAM 122. Further, an area for setting an AT flag indicating that the AT is also controlled in the RT gaming state is provided in the RAM 122.

  Hereinafter, a gaming operation in the slot machine 1 according to this embodiment will be described. Here, first, a special process executed when the slot machine 1 is activated will be described, and then a process when each game is repeatedly performed in the slot machine 1 will be described. In the following description, the term “game” means, in a narrow sense, from the operation of the start lever 11 until the reels 3L, 3C, 3R are stopped. However, when a game is played, the number of bets before the operation of the start lever 11 is set, and medals are paid out and the game state is shifted after the reels 3L, 3C, 3R are stopped. Is also included in the “game” in a broad sense. In the following description, descriptions of processes not related to the present invention may be omitted.

  When the setting key switch 92 is in the ON state and the slot machine 1 is activated, the mode shifts to the setting change mode, where the RAM 112 is initialized and a new setting value is set by the setting switch 91, and the start lever 11 is operated. When the setting key switch 92 is turned off after confirming the new setting value by the above, the process shifts to a game control process described below.

  On the other hand, when the slot machine 1 is started with the setting key switch 92 turned OFF, it is diagnosed whether the data in the RAM 112 is damaged. If the data in the RAM 112 is damaged, the process proceeds to a RAM abnormality error process. The RAM abnormality error processing cannot be canceled by operating the first reset switch 48 or the second reset switch 93. As described above, the setting key switch 92 is turned on to start the slot machine 1 again and set the setting value again. It cannot be canceled without resetting.

  When the data in the RAM 112 is not broken, that is, when the data when the power of the previous slot machine 1 is turned off remains normal, the data stored in the RAM 112 is left as it is and will be described next. The game control process is shifted to. In other words, when the slot machine 1 is activated with the setting key switch 92 turned off, if the data in the RAM 112 is not corrupted, the game is resumed from the previous state when the slot machine 1 was disconnected.

  FIG. 17 is a flowchart showing a game control process performed by the CPU 111 of the game control board 101 for each game. This process is also executed after the power is turned on and a predetermined boot process is performed, or immediately after the setting is changed by operating the setting switch 91. When the process of one game is started, first, an initial process including a process of clearing a predetermined area of the RAM 112 is performed (step S101).

  Next, the number of bets is set by operating one BET button 14 or MAXBET button 15 or by inserting medals from the medal insertion slot 13, and operating the start lever 11 to substantially change the game. BET processing for instructing start is performed. (Step S102). In the BET process, not only the bet number is set, but also by operating the settlement button 16, the already set bet number and credits can be settled and the corresponding number of medals can be paid out. When the bet number has already been set and credits remain, the bet number is settled by the first operation of the settlement button 16 and the credit is settled by the second operation.

  Further, in the slot machine 1 according to this embodiment, the number of bets for starting the game is limited to 3, and the start lever 11 does not become effective until 3 is set as the number of bets. If the player has won a replay in the previous game, the same number of bets as the previous game is automatically set by the flag during the replay game (the flag during the replay game is erased at this stage).

  In the BET process, every time the set bet number is increased by 1 (increment to 3 in the automatic setting after the operation of the MAXBET button 15 or replay winning), the BET indicating the set bet number A command is transmitted to the effect control board 102. Further, when the settlement button 16 is operated and the already set bet number or credit is settled, a settlement command is transmitted to the effect control board 102.

  When the bet number is set by the BET process and the start lever 11 is operated, a random number for internal lottery is extracted, and based on the extracted random number value, each combination determined according to the gaming state and the bet number A lottery process for determining whether or not winning is permitted is performed (step S103). In the lottery process, the number of determination values of the lottery target combination determined according to the gaming state is sequentially added to the extracted random number, and it is determined that the lottery target role is won when it overflows. However, if the winning flag of Big Bonus (1), Big Bonus (2) or Regular Bonus has been carried over from the previous game, the lottery target will be Big Bonus (1), Big Bonus (2) or Regular Bonus Even if it overflows at some point, it won't win again.

  If it is determined that the winning combination of the big bonus (1), big bonus (2), or regular bonus has been carried over from the previous game, and the winning combination of the small bonus or replay is determined, It is set by overlapping. If there is a lottery target combination determined to have been won in the lottery process, the winning flag is set in the RAM 112. In the lottery process, a winning status notification command indicating the setting status of the winning flag in the RAM 112 is transmitted to the effect control board 102.

  When the lottery process is completed, a reel rotation process is performed (step S104). In the reel rotation process, the reel motor is operated on the condition that a predetermined time (for example, 4.1 seconds) has elapsed from the start of rotation of the reels 3L, 3C, and 3R in the previous game. 3ML, 3MC, and 3MR are driven to start rotation of all the left, middle, and right reels 3L, 3C, and 3R. When predetermined conditions (detection of the reference position by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed) from the start of rotation of the reels 3L, 3C, 3R are satisfied, the stop buttons 12L, 12C, 12R Is enabled.

  After that, when the stop buttons 12L, 12C, and 12R are operated by the player, the reel motors 3ML, 3MC, and 3MR are stopped according to the stop control table selected according to the setting state of the winning flag, and the reels 3L, 3C, and Stop the rotation of 3R. Each time the rotation of the reels 3L, 3C, 3R is stopped, a reel stop command indicating the type of the stopped reel and the type of symbol is transmitted to the effect control board 102.

  When the driving of each of the reels 3L, 3C, and 3R is stopped, a winning determination process is performed to determine whether any of the above-mentioned role symbols is derived and displayed on any winning line in the display mode at the time of stopping. (Step S105). If it is determined in this winning determination process that one of the winning combinations has been won (not a winning combination, but including RT symbol derivation), processing according to the winning combination is performed.

  For example, when winning a small combination, the number of payouts according to the type of the small combination won is set. When winning a replay, a replay game flag is set. When the big bonus (1) or the big bonus (2) is won, a big bonus medium flag is set in the RAM 112 and the big bonus (1) winning flag or the big bonus (2) winning flag is erased. When the regular bonus is won, the regular bonus medium flag is set and the regular bonus winning flag is erased. Furthermore, a winning information command indicating the type of winning combination (not a winning combination but including RT symbol derivation) is transmitted to the effect control board 102.

  When the winning determination process ends, a payout process is performed (step S106). In the payout process, the credit is increased by the number of payouts set in the winning determination process. However, when the number of credits accumulated as data reaches 50, the hopper motor 82 is driven to pay out an excess number of medals from the medal payout slot 71. Also, in the payout process, the number of digestion games and winning games in the regular bonus, the total number of payout of medals in the big bonus, or the number of RT digestion games are counted, and when the respective end conditions are met, the regular bonus, Processing to end the big bonus or RT gaming state is also performed.

  In the payout process, the winning flags for various small roles and replays are also erased, but the winning flags for the big bonus (1), big bonus (2), and regular bonus are awarded to the winning combination in the game. If not, it is carried over to the next game without being erased. Furthermore, at the end of the payout process, that is, at the end of one game, a game state command indicating the game state of the next game is sent to the effect control board 102. Then, the process for one game ends, and the process for the next one game starts.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 shifts the game state between the normal game state, the regular bonus, and the big bonus, and controls the command according to the progress of the game. It is transmitted to the substrate 102. On the other hand, the CPU 121 of the effect control board 102 independently performs effects processing such as game navigation, navigation notification, AT, and reproduction of bonus medium music based on commands received from the game control board 101. Hereinafter, the process of the effect performed by the control on the effect control board 102 side will be described.

  18 and 19 are flowcharts showing processing executed by the CPU 121 of the effect control board 102. On the side of the effect control board 102, it is determined whether or not a command sent from the game control board 101 has been received (step S201). When any command is received from the game control board 101, the game operation timer starts again from 0 (step S202). Then, when any command is received from the game control board 101, it is determined what kind of the received command is (step S203).

  If the received command type is the BET command transmitted in step S102, the player has performed an operation to advance the game except when the player has won a replay in the previous game. Therefore, if the audio output from the speakers 7L, 7R, 7U is muted, it is canceled (step S204). If the number of bets is automatically set based on the replay winning, it cannot be said that it is due to the player's operation, but this process is almost the same as the timing when the third stop button was operated in the previous game. Since it is done, there is no particular problem.

  Next, it is determined whether or not the received BET command indicates that 1 is set as the bet number (step S205). If it is indicated that 2 or 3 has already been set as the bet number, the process returns to step S201. If it indicates that 1 is set as the bet number, the game state to be started is referred to as a big bonus start game by referring to the game state for two times stored in the RAM 122 in step S249 (described later) of the previous game. It is determined whether or not (step S206).

  If it is a big bonus start game, the switching display of the characters A, B, and C started in step S251 (described later) and performed on the liquid crystal display 4 is stopped (step S207). Then, information indicating the type of the stopped character is stored in the RAM 122 (step S208). Furthermore, the reproduction of the bonus medium music in the big bonus corresponding to the character type is started. The bonus medium music thus reproduced is started to be output from the speakers 7L, 7R, and 7U (step S209). Then, the process returns to step S201.

  If the game to be started is not the big bonus start game, the game state to be started is referred to the regular bonus (the big bonus is in the big bonus) with reference to the game state for two times stored in the RAM 122 in step S249 (described later) of the previous game. It is determined whether or not it is a starting game (not including the provided one) (step S210). If the game is a regular bonus start game, playback of the medium-bonus music corresponding to the regular bonus is started. The bonus medium music thus reproduced starts to be output from the speakers 7L, 7R, and 7U (step S211). Then, the process returns to step S201.

  If the game to be started is not a regular bonus start game, the selection of the character B is won in the navigation lottery, and it is determined whether or not the B notification flag is set in the RAM 122 (step S212). If the B notification flag is set, the winning information stored in the RAM 122 in step S249 (described later) of the previous game is referred to, and one of the three choice small combinations 1 to three choice small combinations 3 is determined in the previous game. It is determined whether or not a prize has been won (step S213).

  If you have won any of the three choices 1 to 3 in the previous game, you will be notified by navigation on the LCD 4 with the effect by the character B, and you will be given the right to play the game. This is notified to the player (step S214). Then, the process proceeds to step S215. From the display result of the variable display device 2, the player is given the right of game navigation if the player has not won any of the three alternative small roles 1 to 3 in the previous game. Since this is not known, the navigation notification is not performed and the process proceeds to step S215.

  In step S215, the B notification flag set in the RAM 122 is erased, and the player is given the right to perform game navigation in the normal gaming state after the end of the big bonus. Set. Then, the process returns to step S201. If the B notification flag is not set in step S212, the process directly returns to step S201.

  If the received command type is the winning status notification command transmitted in step S103, the player has performed an operation (operation of the start lever 11) to advance the game. If the audio output from 7L, 7R, 7U is muted, it is canceled (step S216). Next, the winning situation indicated by the received winning situation notification command (that is, the setting situation of the winning flag in the current game) is stored in a predetermined area of the RAM 122 (step S217).

  Next, with reference to the gaming state stored in the RAM 122 in step S249 (described later) of the previous game, it is determined whether or not the gaming state in the current game is RT (step S218). If the gaming state in the current game is RT, it is determined whether or not the AT flag is set in the RAM 122 (step S219). If the AT flag is set, the winning situation stored in the RAM 122 is referred to and it is determined whether or not one of the three alternative small combinations 1 to three selective small combinations 3 has been won (step S220).

  If one of the three choice small roles 1 to three choice small roles 3 is elected, information corresponding to the type of one of the three choice small roles 1 to three choice small roles 3 is liquid crystal The information is displayed on the display 4 and notified to the player (step S221). Then, the process returns to step S201. If the AT flag has not been set in step S219, or if none of the third choice small combination 1 to three choice small combination 3 has been won in step S220, the processing directly returns to step S201.

  If the game state in this game is not RT, the AT flag in the RAM 122 is erased. Of course, when the AT flag is not set in the RAM 122, only the state is maintained (step S222). Next, referring to the gaming state stored in the RAM 122 in step S249 (described later) of the previous game, it is determined whether or not the gaming state in the current game is a normal gaming state (step S223). If the game state in the current game is a normal game state, it is determined whether or not a navigation flag is set in the RAM 122 (step S224). If the navigation flag is set, it is determined whether or not the small combination 1 + small combination 2 is won by referring to the winning situation stored in the RAM 122 (step S225).

  If the small combination 1 + small combination 2 is won, information indicating that is displayed on the liquid crystal display 4 to notify the player (step S226). According to this information, the player reverse-presses the stop buttons 12L, 12C, 12R, and operates the stop button 12L at the timing when the 5th or 6th symbol is positioned on the winning line where the “bell” is tempered. The RT display can be derived by the variable display device 2. Then, the process returns to step S201. If the navigation flag is not set in step S224, or if the small combination 1 + small combination 2 is not won in step S225, the process directly returns to step S201.

  If the game state in the current game is not the normal game state, whether or not the game state in the current game is a big bonus by referring to the game state stored in the RAM 122 in step S249 (described later) of the previous game. Is determined (step S227). If the game state in the current game is not a big bonus, the process directly returns to step S201.

  If the game state in this game is a big bonus, it is determined that the character type stored in step S208 is character A, and the winning situation stored in the RAM 122 is selected as a small role 1 in this game. It is determined whether it is indicated (step S228). If the character type is character A and the small role 1 is won, a navigation lottery is performed by random lottery with a winning probability of about e / d2 (step S229). As a result, the player has the right of game navigation. It is determined whether or not it has been decided to give (step S230). If it is determined that the game navigation right is to be given to the player, an A notification flag is set in the RAM 122 (step S231), and the process returns to step S201. If it is determined not to grant the game navigation right to the player, the process directly returns to step S201.

  If the character type is not character A, or if the winning status notification command does not indicate that the small role 1 is won, the character type stored in step S208 is character B, and It is determined whether or not the winning situation stored in the RAM 122 indicates that one of the three choice small combinations 1 to three choice small combinations 3 has been won (step S232).

  If the character type is character B and one of the three choice small combinations 1 to three selection small combinations 3 is won, a navigation lottery by a random lottery with a winning probability of about e / 3g is performed (step S233). As a result, it is determined whether or not to give the player the right of game navigation is determined (step S234). If it is determined that the game navigation right is to be given to the player, a B notification flag is set in the RAM 122 (step S235), and the process returns to step S201. If it is determined not to grant the game navigation right to the player, the process directly returns to step S201.

  If the character type is not character B, or if the winning status notification command does not indicate that any of the three alternative small roles 1 to 3 is selected, it is stored in step S208. It is determined whether the character type is character C and the winning situation stored in the RAM 122 indicates that the small role 2 is won (step S236). If the character type is character C and the small role 2 is won, a C notification flag is set in the RAM 122 (step S237), and the process returns to step S201. If the character type is not the character C or does not indicate that the small role 2 is won, the process directly returns to the process of step S201.

  If the received command type is the reel stop command transmitted in step S104, the player has performed an operation (operation of the stop buttons 12L, 12C, 12R) to advance the game. Therefore, if the audio output from the speakers 7L, 7R, 7U is muted, it is canceled (step S238). Then, the process returns to step S201.

  If the received command type is the winning information command transmitted in step S105, the winning information indicated by the received winning information command is stored in a predetermined area of the RAM 122 (step S239). Next, with reference to the gaming state stored in the RAM 122 in step S249 (described later) of the previous game, it is determined whether or not the gaming state in the current game is a normal gaming state (step S240).

  If the game state in the current game is a normal game state, it is determined whether or not the winning information stored in the RAM 122 indicates that the RT symbol has been derived (step S241). If it does not indicate that the RT symbol has been derived, the process directly returns to step S201. If it indicates that the RT symbol has been derived, it is further determined whether or not the navigation flag is set in the RAM 122 (step S242). If the navigation flag is not set, the process directly returns to step S201.

  If the navigation flag is set, game navigation is being performed in this game, and the RT symbol is derived to the variable display device 2 as a result of the player operating the stop buttons 12L, 12C, and 12R according to the game navigation. It will be. In this case, the navigation flag set in the RAM 122 is erased, and in the RT based on the RT symbol derived here, the gaming state is controlled by the AT on the side of the effect control board 102, so the RAM 122 An AT flag is set in (Step S243). Then, the process returns to step S201.

  If the game state in the current game is not the normal game state, the game state stored in the RAM 122 in step S249 (described later) of the previous game is further referred to to determine whether the game state in the current game is a big bonus. Is determined (step S244). If the game state in the current game is a big bonus, it is determined whether or not the C notification flag is set in the RAM 112 (step S245). If the C notification flag is set, it is determined whether or not the winning information stored in the RAM 122 indicates the winning of the small role 2 (step S246).

  If the small role 2 is won, the navigation notification is given on the liquid crystal display 4 by the effect by the character C to notify the player that the right of game navigation has been granted (step S247). Further, the C notification flag set in the RAM 122 is deleted, and a navigation flag is set in the RAM 122 (step S248). Then, the process returns to step S201. If the game state in the current game is not a big bonus, if the C notification flag is not set in the RAM 122, or if the small role 2 has not been won, the process returns to step S201.

  If the received command type is the gaming state command transmitted in step S106, the gaming state stored in the gaming state storage area for two games in the RAM 122 is shifted (received in the previous game). The gaming state indicated by the gaming state command is evicted), and the gaming state indicated by the gaming state command received in the current game is stored (step S249).

  Next, with reference to the game state for two times stored in the RAM 122, it is determined whether or not the big bonus starts from the next game (step S250). If the big bonus starts from the next game, the character switching display for switching the characters A, B, and C to be displayed on the liquid crystal display 4 for a certain period is started (step S251). Then, the process returns to step S201.

  If the big bonus does not start from the next game, it is further determined by referring to the game state stored twice in the RAM 122 whether or not the big bonus ends in the current game (step S252). If the big bonus ends in this game, it means that the game state so far was a big bonus, so the bonus medium music is being played. Therefore, the reproduction of the bonus medium music is stopped so that it is not output from the speakers 7L, 7U, 7R even if it is not muted (step S253).

  Next, it is determined whether or not the navigation lottery is won by the selection of the character A and whether or not the A notification flag is set in the RAM 122 (step S254). If the A notification flag is set, the liquid crystal display 4 performs navigation notification with the effect by the character A to notify the player that the right of game navigation has been granted (step S255). Further, the A notification flag is erased and a navigation flag is set in the RAM 122 (step S256). Then, the process returns to step S201. If the A notification flag is not set, the process directly returns to step S201.

  If the big bonus does not end in this game, the regular bonus (not including the one provided in the big bonus) will be ended in this game with reference to the game state stored twice in the RAM 122. It is determined whether or not (step S257). If the regular bonus ends in this game, it means that the game state so far has been a regular bonus, and the music in the bonus is being played. Therefore, the reproduction of the bonus medium music is stopped so that it is not output from the speakers 7L, 7U, 7R even if it is not muted (step S258). If the regular bonus does not end in this game, the process directly returns to step S201.

  When the received command type is the settlement command transmitted in step S102, the settlement button 16 is operated by the player, and the number of bets set for the next game (excluding those based on the replay winning) Or credits are settled. In this case, it is considered that the player has interrupted the game, but there may be a big bonus or a regular bonus. In this case, since the music in bonus is being reproduced, the output of the sound is muted so that the sound is not output from the speakers 7L, 7R, 7U with a high volume (step S259).

  Here, for example, in the case where the bet number is set using credit, only the bet number is settled by the first settlement button 16 operation, and the bonus song is transmitted by the settlement command transmitted at this time. The output is muted. Even if the settlement command is transmitted when the credit is settled by operating the settlement button 16 for the second time, the output of the bonus medium music is only muted. When the settlement button 16 is operated in a state where the bet number has not yet been set, the output of the bonus medium music is muted by the settlement command transmitted here. Then, the process returns to step S201.

  If the received command type is another command, processing corresponding to each command type is executed (step S260). Since the processing here is not related to the present invention, detailed description thereof is omitted. Thereafter, the process returns to step S201.

  If it is determined in step S201 that a command has not been received, it is determined whether or not the gaming operation timer has elapsed the predetermined time (step S261). If the predetermined time has elapsed, it is during the big bonus or regular bonus, and the music being played in the bonus may be played, so this sound is not output from the speakers 7L, 7R, and 7U with a high volume. As described above, the audio output is muted (step S262). Then, the process returns to step S201. If the game operation timer has not timed the predetermined time, the process directly returns to step S201.

  As described above, in the slot machine 1 according to this embodiment, the RT symbol is derived to the variable display device 2 in the normal gaming state, so that the medal payout rate exceeds 1, which is advantageous to the player. The gaming state is controlled by the RT that becomes a thing. The RT symbol is a reel 3C which is operated by pressing the stop buttons 12L, 12C and 12R in the reverse direction when the small role 1 + the small role 2 is won in the normal gaming state and is stopped before the left reel 3L. 3R can be derived on condition that the stop button 12L is operated at the timing when the 5th or 6th symbol is positioned on the winning line where the “bell” is tempered. However, if the small combination 1 + small combination 2 is not won, the stop buttons 12L, 12C are operated in the same operation procedure as that for deriving the above RT symbols including the case where only the small combination 1 is won. , 12R is not operated, the RT symbol is not derived.

  In addition, the fact that the RT symbol has been derived to the variable display device 2 means that the small role 1 or the small role 2 has been missed, and the player receives 12 pieces when winning the small role 1 or the small role 2 However, the profits obtained by the RT of 200 games controlled thereby are larger than the lost 12 medals. On the other hand, if the left stop button 12L is operated first or second without reversely pressing the stop buttons 12L, 12C, 12R, as long as the small part 1 is won (the small part 2 is also won simultaneously) Regardless of the operation timing of each of the stop buttons 12L, 12C, and 12R, the player will always win the small role 1, and the player can surely obtain the profit of 12 medals. it can.

  Here, in the normal gaming state, when the right of game navigation is granted, when winning the small role 1 + small role 2, information that can be specified to that effect is displayed on the liquid crystal display 4, so that the player According to the notified information, the stop buttons 12L, 12C, and 12R are operated by reverse pressing, and the reels 3C and 3R that are stopped before the left reel 3L are set to 5 on the winning line where the “bell” is tempered. The stop button 12L can be operated at the timing when the No. 6 or No. 6 symbol is located. If it is assumed that there is no mistake in this operation, if information indicating the winning of the small combination 1 + small combination 2 is notified, the gaming state can be surely controlled by the player's selection. In RT based on the derivation of RT symbols when the right of game navigation is granted, the gaming state is further controlled by the AT, and the procedure for winning a prize is the exclusive three choice small role 1 to three choice small role 3 When you win one of them, the type will be announced.

  On the other hand, when the right of the game navigation is not granted in the normal gaming state, even if the small role 1 + small role 2 is won, the player does not know this, but even in this case, the small role 1 + small As long as the winning combination is won, the RT symbol can be derived by performing the same stop operation as described above, and the gaming state can be controlled by the RT. In this way, even if the right of game navigation is not granted in the normal gaming state, the stop button 12L, 12C, If 12R is operated, there is a chance for RT to control the gaming state.

  However, when such a stop operation is performed when the right of game navigation is not granted in the normal gaming state, if the small role 1 + the small role 2 is not actually won, Even if you are elected, there will be a disadvantage that you will miss it. Furthermore, even if the RT symbol can be derived accidentally by performing such a stop operation when the right of game navigation is not granted in the normal gaming state, in the RT controlled based on this, the AT of the AT is controlled. There will also be a disadvantage that the right is not granted.

  In other words, when the right of the game navigation is not granted in the normal gaming state, there is a risk that the small winning combination 1 won alone may be missed, and there is a disadvantage that AT is not added in RT, RT design The game will have a strategic nature, such as whether to challenge the derivation of the game, or to prevent the withdrawal of the small part 1 without challenging the derivation of the RT symbol, and to obtain 12 medals with certainty. be able to.

  However, when the right of game navigation is given in the normal gaming state, it is not disadvantageous to the player if it is assumed that an operation procedure for deriving the RT symbol can be performed (small role 1 or small Loss occurs in the short term due to the loss of the role 2, but profits more than that loss can be obtained in RT), so the specifications that allow RT to control the gaming state by deriving RT symbols will not be wasted . In addition, since the AT is added to the RT, it is also motivated to perform an operation procedure for deriving the RT symbol.

  On the other hand, when the right of game navigation is not granted in the normal gaming state, no notification is given even if the small role 1 + small role 2 is won, but in this case, the player presses the stop buttons 12L, 12C, 12R in order. Unless the left stop button 12L is operated for the third time, the winning combination 1 is always made. In a normal gaming state, the small combination 1 may be won alone, and in this case, the small combination 1 will always be won in the operation procedure such as forward pressing. In addition, the winning probability of the small role 1 alone is higher than the winning probability of the small role 1 + small role 2. As a result, when winning the small role 1 when the game navigation right is not granted, the player is informed from the display result of the variable display device 2 that the small role 1 + small role 2 has been won. Nothing will happen.

  Further, in the slot machines in general including the slot machine 1 according to this embodiment, the operation sequence most frequently used when the player operates the stop buttons 12L, 12C, 12R is the order of left → middle → right. It is a forward press to operate. As long as the stop buttons 12L, 12C, and 12R are pressed in order, this will not be missed when the small role 1 is elected alone. Therefore, while the player is performing the stop operation as usual, The disadvantage of missing the small role 1 is never given.

  Further, if the RT symbol can be derived even when the right of game navigation is not granted (the AT will not be added to the RT), the small role 1 or the small role 2 in the one game is The profit that the player can obtain in the subsequent RT is greater than the loss caused by the loss. However, considering the winning probability when winning only for small role 1 and the winning probability when winning small role 1 + small role 2, until the RT symbol is derived when the right of game navigator is not granted The expected value of the total loss that missed the small role 1 elected alone will be larger than the profit obtained in the subsequent RT. For this reason, a strategy for selecting high risk / high return or low risk / low return is generated, so that the interest of the game can be further improved.

  In addition, when the right of game navigation is not granted in the normal gaming state, the stop button 12L, 12C, 12R is reversely pressed, and the 5th or 6th symbol is positioned on the winning line where the “bell” is tempered. The disadvantage that occurs to the player when the stop button 12L is operated at the timing includes the fact that even if the small role 1 is won alone, it is missed. In other words, the control based on the gaming nature inherent in the slot machine in which the game is advanced based on the display result of the variable display device 2 can give a disadvantage to the player in such a case.

  Further, when the right of game navigation is not granted in the normal gaming state, the stop button 12L, 12C, 12R is operated by reverse pressing, and the 5th or 6th symbol is positioned on the winning line where the “bell” is tempered. When the stop button 12L is operated at the timing, the disadvantage that occurs to the player is that, even if the small symbol 1 + small role 2 is won and the RT symbol is derived, no AT is added in RT based on this It is included. This makes it less effective to perform such a stop operation when game navigation rights are not granted, allowing the player to recognize the granting of game navigation rights as a more special one. It becomes.

  By the way, in the game in the normal gaming state after the end of the big bonus, when the small role 1 and the small role 2 are won at the same time, the player is given the right of game navigation to notify the player of information indicating that fact. Whether or not to do so is determined when the last big bonus is controlled.

  Here, before the first game of the big bonus is started, the characters A to C are sequentially switched and displayed on the liquid crystal display 4, and the first game of the big bonus is performed by the player's betting number setting operation. When the number of bets for the game is determined, the character type displayed at that time is the character type applied to the navigation notification that notifies the player when the game navigation right is granted. Also, the bonus medium music that is played / output in the big bonus differs depending on the type of the character. As described above, since the contents of the effect during the big bonus change depending on the selection of the character type according to the bet number setting timing, the interest in selecting the character type is increased.

  Further, when the character A is selected, the small role 1 is determined when the big bonus is used to determine whether or not to give the player the right of game navigation in the normal gaming state after the end of the big bonus. Depending on the type of the selected character, the winning of any one of the three selections 1 to 3 when the character B is selected, and the winning of the small combination 2 when the character C is selected. . In addition, the probability that navigation is performed at each opportunity is also different from e / d2, e / 3g, and 1 (= e / e).

  However, considering the winning probabilities of each combination, the probability that the right of game navigation will be granted before the end of the big bonus is substantially the same regardless of which type of character is selected. Thus, since the selection of the character at the start of the big bonus affects not only mere production but also the progress of the game itself, the player's sense of intervention in the game can be enhanced, thereby improving the interest of the game. .

  Furthermore, when it is determined that the right of game navigation is to be granted in the big bonus, a navigation notification is made to notify the player of this, but the character A is also selected at the timing of the navigation notification. Sometimes at the end of the big bonus, when character B is selected, when the number of bets for the next game is set, when character C is selected, immediately after winning the small role C, depending on the type of character selected Is different. In this way, the selection of the character at the start of the big bonus also makes a difference in the timing of the notification of the navigation performed when it is determined that the right of game navigation is decided, so it is interesting to select the character type. It can be further increased.

  Further, the number of continuous games of RT controlled by the derivation of the RT symbol is set to 200 games. However, unless the regular bonus, the big bonus (1) or the big bonus (2) is won, the regular bonus, the big bonus ( RT won't end just by winning an internal lottery for 1) or Big Bonus (2). Therefore, the RT profit of 200 games is not lost without the player's involvement.

  Further, in the slot machine 1 according to this embodiment, when the gaming state is the big bonus or the regular bonus, the music in the bonus is continuously reproduced. As long as the gaming state is controlled to the big bonus or the regular bonus, the bonus medium music is reproduced without interruption between the games and between the games, and is output from the speakers 7L, 7R, and 7U. . However, even if the gaming state is controlled to be a big bonus or a regular bonus, if the player has not performed a game operation (a setting operation for a bet number, a start operation) for a predetermined time, the player interrupts the game. Therefore, the outputs from the speakers 7L, 7R, 7U are muted.

  In addition, even before a predetermined time has passed without a player performing a game operation, the player adjusts the settlement button 16 between games and sets the bet number or credit set for the next game. Is settled, it is considered that the player has interrupted the game, and the outputs from the speakers 7L, 7R, 7U are muted. As a result, even though the game is interrupted, the bonus medium music is not output from the speakers 7L, 7R, and 7U at a high volume, and the surrounding players are not disturbed.

  Further, in the slot machine 1 according to this embodiment, by attaching the connector restricting member 500 including the attachment side member 510 and the connector cover 520 to the board case 200, the game control board accommodated in the board case 200 is stored. The board-side connector 620a and the cable-side connector 610a are restricted from being removed, and in this state, the board case 200 is attached to the mounting base 250, and the fixing member 255 and the sealing piece 232 are fixed to each other. If the removal of the connector restricting member 500 is restricted and the sealing piece 232 of the board case 200 is broken to release the fixation between the board case 200 and the housing (mounting base 250), the board side connector The cable-side connector 610a cannot be removed from the 620a. In other words, the cable-side connector 610a cannot be removed without leaving a trace that the sealing piece 232 is broken, and a fraudulent instrument such as a driving instrument cannot be connected without leaving a trace. You will be able to discover that there is a possibility that

  Further, when the game control board 101 is replaced together with the board case 200 containing the game control board 101 due to a failure or the like, the sealing piece 232 is broken to fix the board case 200 and the housing (mounting base 250). If released, the connector restricting member 500 can be detached from the board case 200 and the cable side connector 610a can be removed from the board side connector 620a. Therefore, the connector restricting member 500 can be destroyed or the board case 200 can be destroyed. The cable-side connector 610a can be separated from the board-side connector 620a without opening.

  Further, the connector restricting member 500 is composed of an attachment side member 510 and a connector cover 520. After the attachment side member 510 is attached to the board case 200, the cable side connector 610a is connected to the board side connector 620a, and the board is in that state. The cable-side connector 610a cannot be removed from the board-side connector 620a by being attached to the attachment-side member 510 so as to cover a part of the cable-side connector 620a from above. Is connected to the board-side connector 620a, and then the locking cylinder 522 of the connector cover 520 is fitted into the locking hole 513a of the locking hole 513 of the attachment-side member 510 located around the board-side connector 620a. The connector cover 520 is simply attached to the attachment side member 510. Since part of the cable-side connector 610a is covered and the movement of the cable-side connector 610a in the unplugging direction is restricted, the assembly work is reduced when the removal of the cable-side connector 610a from the board-side connector 620a is restricted. it can.

  Further, even when the game control board 101 is housed in the board case 200, it is only necessary to connect the cable side connector 610a to the board side connector 620a as it is and then attach the connector cover 520. In this case, the assembly work can be more effectively reduced when the removal of the cable-side connector 610a from the board-side connector 620a is restricted.

  In addition, the connector cover 510 does not cover the entire connection portion between the cable-side connector 610a and the board-side connector 620a, but covers only a part of the cable-side connector 610a in the pulling direction side. Not only can the connector 610a be securely removed from the board-side connector 620a, but also the material required for manufacturing the connector cover 510 can be reduced.

  In addition, the connector cover 520 is attached to the attachment side member 510 with only one locking cylinder 522, but a rib that contacts the surface of the base piece 510a of the attachment side member 510 is provided on one side wall of the connector cover 520. Since 521b and 521b are formed and the movement of the connector cover 520 is restricted, the removal of the cable side connector 610a from the board side connector 620a can be reliably restricted.

  In addition, inwardly engaging portions 511 and 511 are formed at both ends extending from the base piece 510a of the attachment side member 510, and the engaging portions 511 and 511 are elastically deformed outward. In this state, the mounting member 510 is attached to the board case 200 by being assembled to the board case 200 and engaged with the locking grooves 514 and 514 formed on the back surface of the board case 200. Since the member 500 can be attached to the board case 200 without using other members such as screws and pins, the number of components can be reduced.

  Further, when the attachment side member 510 constituting the connector restricting member 500 is attached to the board case 200, the opposing surfaces of the attachment side member 510 to the base case 510 a and the upper pieces 510 c, 510 c with respect to the board case 200 are the steps in the upper case 203. The upper surface of the portion 203b and the bottom surface of the concave portion 203f are in contact with each other, and it is possible to effectively prevent attachment of unauthorized parts or the like between the connector restricting member 500 and the surface of the board case 200.

  Further, since the attachment side member 510 and the connector cover 520 constituting the connector restricting member 500 are both made of a transparent synthetic resin material, the visibility in the board case 200 may be impaired by the connector restricting member 500. Therefore, there is no problem in monitoring the game control board 101. Further, even when an unauthorized part is attached to the gap between the connector restricting member 500 and the board case 200, it can be easily found.

  Further, the connector connection between the game control board 101 and the inserted medal sensor 44, that is, the connection between the board side connector 620a of the game control board 101 and the cable side connector 610a of the cable 600a, the cable side connector 611a of the cable 600a and the operation unit. Regarding the connection between the board-side connector 621a of the relay board 107 and the connection between the board-side connector 622g of the operation part relay board 107 and the cable-side connector 612g of the cable 601g, the connection between these connectors is released. It is restricted by the member 650. As a result, any connector between the game control board 101 and the inserted medal sensor 44 is replaced with a connector such as an unauthorized driving tool and connected to the game control unit 110 of the game control board 101 and a signal related to the progress of the game. It is difficult to carry out fraudulent activities such as illegally inputting / outputting information, so that illegal sales can be effectively prevented.

  Further, in order to release the connector connection between the game control board 101 and the inserted medal sensor 44, the sealing piece 232 of the board case 200, the connection piece 522a of the connector cover 520, and the connection piece 684a of the cover member 680 are broken. As a result, when even one connector connection between the game control board 101 and the inserted medal sensor 44 is released, the trace remains and it is extremely difficult to erase the trace. , The above fraud can be more effectively suppressed.

  In addition, there is only one relay board between the game control board 101 and the inserted medal sensor 44, but in the case of passing through a plurality of relay boards, the removal of all connector connections existing between them is restricted. It is preferable to replace one of the connectors between the game control board 101 and the inserted medal sensor 44 with a connector such as an illegal driving tool and connect to the game control unit 110 of the game control board 101. Since it becomes difficult to perform an illegal act such as illegally inputting / outputting a signal related to the progress of the game, it is possible to effectively prevent the implementation of illegal business.

  Also, the first electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 81 that input signals to the game control board 101 according to the progress of the game and the progress of the game Of the second electronic components 3ML, 3MC, 3MR, 82 for which signals are output from the game control board 101 in response, a connector restricting member is provided only for the connector connection between the inserted medal sensor 44 and the game control board 101. The release of the connection between each other is regulated. In other words, if there is no signal, the inserted medal sensor 44 cannot advance the game (if the signal from the inserted medal sensor 44 is not input, the number of bets cannot be set and the game cannot be started) and the game control. The connector restricting member is provided only for the connector connection with the board 101 to restrict the release of the connection between the connectors, and the connection between the other electronic components and the game control board 101 is released to drive the instrument. Even if it is replaced with a connector, it will be impossible to automatically advance the game automatically, so that it is possible to prevent fraud with the minimum restrictions, and to disconnect these connectors The number of parts can be reduced.

  In addition, a plurality of signal lines connecting the game control unit 110 and a plurality of electronic components that perform input / output of signals necessary for the progress of the game are provided between the game control board 101 and the operation unit relay board 107. By connecting the cable 600a to the board connector 610a of the game control board 101 and the cable connector 620a, that is, by restricting the release of only one connector connection, a plurality of signal lines are connected to each other. It is possible to restrict the release of the connection, and it is not necessary to prepare a plurality of parts for restricting the release of the connector connection, and the number of these parts can be reduced.

  Even when a plurality of signal lines connecting the game control unit 110 and a plurality of electronic components that perform input / output of signals necessary for the progress of the game are connected via a plurality of cables, the board side connectors are brought close to each other. It is necessary to prepare a plurality of parts for restricting the release of the connector connection by restricting the release of the connection between the plurality of board side connectors and the plurality of cable side connectors with one part. The number of these parts can be reduced.

  Also, the connection between the cable side connector 611a of the cable 600a connecting the game control board 101 and the operation part relay board 107 and the board side connector 621a of the operation part relay board 107 is released, and the operation part relay board 107 and the insertion medal sensor 44. Since the release of the connection between the cable-side connector 612g of the cable 601g and the board-side connector 622g of the operation unit relay board 107 is simultaneously restricted by one connector restricting member 650, the connection of the plurality of connectors is released. It is not necessary to prepare a plurality of parts for regulating the number of parts, and the number of parts can be reduced.

  Further, after the backup power source of the game control unit 110 passes from the game control board 101 via the cable 600a-operation unit relay board 107-cable 601g-inserted medal sensor 44-cable 601g-operation unit relay board 107-cable 600a, Connection to the board side connector 620a of the game control board 101 and the cable side connector 610a of the cable 600a in the state where the power supply to the slot machine 1 is cut off and the cable 600a. The connection between the cable side connector 611a of the operation unit relay board 107 and the board side connector 621a of the operation unit relay board 107 and the connection of the board side connector 622g of the operation unit relay board 107 and the cable side connector 612g of the cable 601g is released. Backup power supply Supply line is disconnected, it can not hold data RAM112 the game control unit 110, so that the lost. That is, when even one connection between the game control board 101 and the inserted medal sensor 44 is released, the backup data held in the RAM 112 of the game control unit 110 is lost.

  On the other hand, in order to connect an unauthorized device such as a driving device, it is necessary to insert / remove the connector. However, even if a special device is selected or a gaming state is illegally used, it is replaced with a regular connector. Therefore, since the data in the RAM 112 is initialized by releasing the connection of the connector, the slot machine 1 set in a state in which the special role is won using the driving tool or in a game state advantageous to the player is used as a game. Unauthorized sales such as providing to a player at the start of business of a store can be prevented.

  The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

  In the above embodiment, the engaging portions 511 and 511 of the attachment side member 510 are elastically deformed outward and engaged with the engaging grooves 514 and 514 formed on the back surface of the substrate case 200. When the attachment member 510 is attached to the substrate case 200 and the substrate case 200 to which the attachment side member 510 is attached is fixed to the attachment base 250 (housing) so as not to be detached, the side piece of the attachment side member 510 510d and 510d are in contact with the inner surfaces of the side walls 250b and 250c of the mounting base 250, and are held between them so that the deformation of the both side pieces 510d and 510d of the mounting side member 510 to the outside is restricted. The configuration is such that it cannot be removed from the case 200.

  On the other hand, for example, when a part of the attachment side member is fixed on the back surface of the substrate case 200 with a screw or a detachable locking pin, and the substrate case 200 is detachably attached to the housing (attachment base). In addition, the screws and the locking pins may be concealed, and the board case 200 may be attached to the housing so that the attachment side member is prevented from being removed from the board case 200. In addition to this, any structure can be used as long as the attachment-side member cannot be detached from the substrate case 200 after the attachment-side member is attached to the substrate case 200 and the substrate case 200 is fixed to the housing. A simple configuration may be adopted.

  In the above embodiment, the connector cover 520 is attached to the attachment side member 510 with only one locking cylinder 522. This configuration is preferable in that the structure of the connector cover 520 and the attachment side member 510 can be simplified. On the other hand, the connector cover 520 is provided with a plurality of locking cylinders 522, and the attachment side member 510 is provided with a locking hole 513a at each corresponding position, so that the connector cover 520 is attached to the attachment side member 510 at a plurality of locations. You may make it attach. By doing in this way, the removal | extraction with respect to the board | substrate side connector 620a of the cable side connector 610a can be controlled more firmly. Furthermore, in this case, it is preferable to attach the connector cover 520 to the attachment side member 510 at a plurality of locations across the connection portion between the cable side connector 610a and the board side connector 620a. The removal of the cable-side connector 610a from the board-side connector 620a can be more firmly regulated.

  In the above embodiment, only the connector connection between the inserted medal sensor 44 and the game control board 101 is provided with the connector restricting member to restrict the release of the connection between the connectors. On the other hand, only the connector connection between the start switch 41 and the game control board 101 may be provided with a connector restricting member to restrict the release of the connection between the connectors. In addition, if the reel is not configured to stop until the reel stop operation is performed after the reel starts rotating, only connector connection between the stop switch 42L, 42C, 42R and the game control board 101 is restricted. A member may be provided to restrict the release of the connection between the connectors. In these cases, the same effect as the above-described embodiment can be obtained.

  In the above embodiment, the backup power is returned from the game control board 101 to the game control board 101 via the inserted medal sensor 44 and supplied to the game control unit 110, so that the connector connection between them is established. When released, the data in the RAM 112 was lost. On the other hand, an electronic component that always inputs and outputs signals necessary for the progress of the game (for example, the start switch 41 or a configuration that does not stop the reel until the reel is stopped after the reel starts rotating. The same effects as those of the above-described embodiment can be obtained even through the stop switches 42L, 42C, 42R, etc.

  Capacitors and batteries that store backup power are mounted on electronic component mounting boards and relay boards (operation unit relay board 107, etc.) for these electronic components, which are required to input and output signals necessary for the progress of the game. A backup power supply line from a capacitor or a battery mounted on the mounting board or the relay board is connected to the game control board via a cable together with a signal line of the electronic component, and is supplied to the game control unit 110. You may make it do. Even in this case, when the connector connection between the mounting board or the relay board and the game control board 101 is released, the data in the RAM 112 will be lost. Since the control board 101 is supplied with backup power via a cable from a capacitor or battery mounted on the mounting board or relay board, the backup power is supplied to the game control unit 110 when the cable is disconnected. In order to continue supply, it is necessary to short-circuit the backup power supply line across the boards, and it is very difficult to release the connector connection while continuing to supply backup power. Connection can be effectively prevented.

  In addition, for example, it is equipped with a signal output circuit that always outputs a specific signal even in the event of a power failure, and always detects a specific signal even in the event of a power failure, and if the detection of a specific signal is interrupted, that fact Is mounted on the game control board 101, and the output path of this specific signal is controlled from the game control board 101 via electronic components that are required to input and output signals necessary for the progress of the game. Returning to the board 101, it is configured to be input to the signal monitoring circuit, and when the game control unit 110 is activated, it is confirmed whether or not the fact that the detection of the specific signal is interrupted is stored in the signal monitoring circuit, and the specific signal In the case where it is stored that the detection is interrupted, the initialization 1 described above may be executed to clear the data stored in the RAM 112. Even in such a case, it is possible to prevent illegal sales such as providing the game machine with the slot machine 1 set in a state where the special role is won using the driving tool at the start of the business of the game shop.

  In the above embodiment, when the slot machine 1 is started without turning on the setting key switch 92, the data is restored to the state before the power interruption using the data unless the data in the RAM 112 is destroyed. I was trying. Here, when the game control unit 110 is activated to return to the state before the power interruption, the CPU 111 transmits a power-on command indicating the winning status of the special role and the game state, and the CPU 121 of the effect control unit 120 When the insertion command is received, the winning situation and the gaming state of the special role may be notified on the liquid crystal display 4, the game number display 51, the credit display 52, and the payout display 53.

  To connect unauthorized devices such as driving tools, it is necessary to turn off the power once (disconnecting the connector without turning off the power will cause a failure). In this case, forcibly disconnect the connector. Even if you use a driving tool to illegally win a special role or set a game state that is advantageous to the player, when the game control unit 110 is restarted, the special role is won or an advantageous game Since it can be easily determined from the outside that it is controlled by the state, the slot machine 1 which is set to a state in which a special role is won using a driving tool or a game state advantageous to the player is operated by a game store. Unauthorized sales such as providing to a player at the start can be effectively suppressed.

  In the above embodiment, the left stop button 12L is operated third in the state where the right to navigate is not granted in the normal gaming state, and the symbol of No. 5 or No. 6 is the “bell” template first. When operating at the timing of being placed on the winning line, if the winning combination of the small combination 1 + small combination 2 is won, the RT symbol is derived and the gaming state is controlled by the RT, but the AT at the corresponding RT The player has the disadvantage of not being able to earn. In addition, in the case where the small role 1 + small role 2 is won or only the small role 1 is won, if the left stop button 12L is operated first or second, the small role 1 that will not be missed. The player had the disadvantage of losing the game. However, on the winning line where the left stop button 12L is operated third in the state where the navigation right is not granted in the normal gaming state and the symbol of No. 5 or No. 6 is the “bell” first. Any one of these disadvantages may be caused to the player when the player is operated at the timing of the position.

  In the above-described embodiment, when the small combination 1 + small combination 2 is won, the left stop button 12L is operated third, and the symbol of No. 5 or No. 6 is the “bell” first. The RT symbol is derived on the condition that it is operated at the timing positioned on the winning line. However, the condition for enabling the RT symbol to be derived is not limited to this. For example, when winning a small combination 1 + a small combination 2 and operating the stop buttons 12L, 12C, 12R in a procedure in which neither the small combination 1 nor the small combination 2 can be derived, the RT symbol is derived with a probability of X percent (10 -X) It is also possible to derive a losing symbol that is not an RT symbol at a ratio of 20%.

  Also, not only when winning the small role 1 + small role 2, but also when winning only the small role 1, the procedure in which the small role 1 cannot be derived, that is, the left stop button 12L is third. It is also possible that the RT symbol can be derived when operated and operated at the timing when the symbol No. 5 or No. 6 is positioned on the winning line where the “bell” is preliminarily placed. However, when the small role 1 is won by itself, the winning notification is not performed, and even if the RT symbol is derived, the RT controlled based on the RT symbol may not be controlled by the AT.

  Further, the stop buttons 12L, 12C, and 12R are pressed in a procedure in which neither the small role 1 nor the small role 2 can be derived either when the small role 1 + the small role 2 is won or when the small role 1 is won alone. If the RT symbols are derived at a certain rate if operated, the proportion of RT symbols derived in the former case is higher than the proportion of RT symbols derived in the latter case. be able to.

  In the above embodiment, the small combination 2 is won only at the same time as the small combination 1 in the internal lottery, but only the small combination 2 may be won alone. Further, there may be a case where only the small combination 2 is won alone, or a case where both the small combination 1 and the small combination 2 are won simultaneously. In the latter case, the RT symbol is operated by operating the stop button 12L on the left third and operating the symbol No. 5 or No. 6 on the winning line where the “bell” is tempered first. Can be derived only if the small role 2 is elected alone, only if the small role 1 and the small role 2 are simultaneously elected, or if the small role 2 is elected alone and the small size Either of the cases where the winning combination 1 and 2 are won simultaneously may be used.

  Here, for example, when the RT symbol can be derived only when the small role 2 is won alone, the small role 2 is won independently when the navigation right is granted in the normal gaming state. The winning notification is performed only when the winning combination is made, and when the small combination 1 and the small combination 2 are simultaneously won, the winning notification is not performed. In short, the winning notification can be made when the right of the game navigation is being notified on condition that the winning situation is such that the RT symbol can be derived depending on the operating procedure of the stop buttons 12L, 12C, 12R. .

  In the above embodiment, it is determined in the big bonus that the right of game navigation is given to the entire normal gaming state after the end of the big bonus. On the other hand, the right of the game navigation is not granted to the whole of the normal gaming state, but every time a small role 1 + small role 2 that allows the RT symbol to be derived in the normal gaming state is won. It is good also as what is given according to the result of a lottery called.

  In the above-described embodiment, when a small role 1 + small role 2 that allows derivation of RT symbols when the right of game navigation is granted in a normal gaming state, information indicating that is displayed on the liquid crystal The notification is made by an image displayed on the display 4. Of course, information that directly indicates that the RT symbol can be derived may be notified instead of the information indicating that the small combination 1 + small combination 2 is won. As such information, for example, an image of “white 7” constituting the RT symbol for the left reel 3L can be displayed on the liquid crystal display 4. On the other hand, an image of “red 7” or “BAR” that does not constitute the RT symbol is displayed on the liquid crystal display 4 to indirectly indicate to the player that the RT symbol can be derived. It may be a thing.

  Further, the information indicating to the player that the RT symbol can be derived is not only notified by an image displayed on the liquid crystal display 4, but also a predetermined sound is output from the speakers 7L, 7R, 7U. The game effect lamps 75A to 75M may be notified by causing them to emit light in a predetermined manner. In addition, an accessory such as a fourth reel may be provided, and information indicating that the RT symbol can be derived by this accessory may be notified to the player.

  In the above-described embodiment, the RT symbols that can cause the gaming state to be controlled by RT are configured by a combination of symbols different from the symbols constituting the winning combination. However, the RT symbol may be a symbol combination of any combination (small role or replay). For example, when the small role 2 in the above embodiment is applied as the RT symbol, when the small button 1 + small role 2 is won and the stop buttons 12L, 12C, 12R are operated by other than the reverse push. Can win the small combination 1 and, when pressed backward, can win the small combination 2 according to the operation timing of the stop button 12L.

  In the above embodiment, even if the RT symbol is derived in a state other than the normal gaming state, the gaming state is not controlled again by the RT. On the other hand, when an RT symbol is derived in the RT gaming state, a RT of 200 games may be newly given from the RT game regardless of the number of remaining games of the RT. In this case, the right of game navigation is granted until the next regular bonus, big bonus (1) or big bonus (2) is won, and there is the right of game navigation even when the game state is at RT. If a small combination 1 + small combination 2 is won, the winning notification may be performed.

  In the embodiment described above, when the checkout button 16 is operated when the music in bonus is being played and the number of bets already set for the next game or the credit is settled, a predetermined time is passed. When the game operation is not performed, the output from the speakers 7L, 7R, and 7U of the music being played is muted so that the surrounding players cannot hear the sound of the bonus music.

  However, in these cases, the output from the speakers 7L, 7R, and 7U may not be muted, but only the volume level of the output audio may be lowered to a certain level. Moreover, it is good also as what switches the music reproduced | regenerated in these cases to another music with a low audio | voice level. That is, the sound of the music may be output from the speakers 7L, 7R, and 7U even in such a case as long as the volume is not high enough to cause trouble for surrounding players. Alternatively, in these cases, the reproduction of the music itself may be stopped. In the case where the reproduction of the music itself is stopped, the reproduction of the music may be started again if necessary in the scene where the mute release event has occurred.

  In the above embodiment, in any gaming state, the game can be started only by setting 3 as the bet number. However, the number of bets that can be set to start the game can be any number in the range of 1 to 3. The number of bets that can be set for each gaming state may be different. Here, when 1 or 2 was set as the bet number in the normal gaming state, the winning probability of the small role in the internal lottery was lowered and the prize was awarded to the small role than when 3 was set as the bet number. The number of payout medals can be increased.

  In the above embodiment, the stop control table is selected in advance based on the setting status of the winning flag, the stop position of the symbol is determined with reference to the stop control table when the reels 3L, 3C, 3R are stopped, and the stop The slot machine that stops the rotation of the reels 3L, 3C, and 3R by the table system that stops the reel at the position has been described as an example. In contrast, based on the current symbol position when the stop condition is satisfied and the setting status of the winning flag, pull-in control is performed so that the symbol of the winning symbol is aligned, or the symbol of the symbol that is not winning The present invention can also be applied to a slot machine that stops the rotation of the reels 3L, 3C, and 3R by a control method in which the removal control is performed so as not to be aligned.

  In the control method, when the operation of the stop buttons 12L, 12C, 12R is detected, the corresponding reels 3L, 3C, 3R are within the range of the maximum stop delay time of 190 milliseconds from the symbol displayed at that time ( It is determined whether or not there is a winning symbol having a winning flag set in a range of a total of five frames including the displayed symbol and the amount drawn.

  If there is a symbol with a winning flag set (determined from the symbol of the role that is given priority for derivation in duplicate wins), select the symbol for winning the winning combination and select the winning line (already stopped) When there is a reel, the winning display mode can be derived along with the symbols on the stopped reel. Otherwise, a symbol for not winning any combination is selected and derived. That is, even when the stop of the reels 3L, 3C, 3R is controlled by this control method, it can be derived by stopping the symbols within the range of the maximum stop delay time after the operation of the stop buttons 12L, 12C, 12R is detected. The display mode corresponding to the setting status of the winning flag is derived as the display result of the variable display device 2.

  In the above embodiment, the variable display device 2 includes the three reels 3L, 3C, and 3R in which a plurality of symbols are arranged in a predetermined order on the outer peripheral portion, and the symbols are driven by rotational driving of these reels 3L, 3C, and 3R. Was variably displayed. However, a device that virtually displays a symbol on a display device such as a liquid crystal display device may be used instead of the variable display device 2 described above.

  In the above-described embodiment, the slot machine to which medals are applied as a game medium used for setting the number of bets and giving game value associated with winning is described as an example. However, the slot machine embodying the present invention may be a slot machine (so-called parrot) to which a game ball used in a pachinko gaming machine is applied as a game medium. When a game ball is used as a game medium, for example, one medal can correspond to five game balls.

  In a so-called parrot, game balls used as game media are stored in a storage tray in the same physical form, and when the player operates the BET button, the game balls stored in the storage tray (upper plate) are stored. The number of game balls corresponding to the BET operation is taken into the parrot via a predetermined take-in route. The number of bets for playing one game is set by the game balls taken inside.

  In addition, when the player operates the checkout button in the parrot, if the bet number has already been set (except when the bet number is automatically set after the replay win), it depends on the set bet number. A number of game balls are discharged to the lower pan provided at the bottom of the slot machine. If the bet number is not set (including the case where the bet number is settled first), the game balls stored in the storage tray are discharged to the lower tray through a predetermined route. The lower plate is provided with a hole through which a game ball stored by a player operating a predetermined lever is passed through the lower plate, and the game ball box (so-called dollar box) is placed under the lower plate. If operated, the game ball owned by the player can be easily transferred to the game ball box.
