Description

  The present invention includes a symbol variation display device that performs a lottery by a player's starting operation and notifies the winning or miss of the lottery result according to a stopped symbol after symbol variation, and a plurality of winning combinations set This is related to a gaming machine that can win a predetermined payout when winning one of the symbols and having a symbol corresponding to the winning combination.

  Conventionally, in a revolving type gaming machine, in particular, a pachislot machine or a parrot (registered trademark) machine, after a predetermined number of medals or pachinko balls as a game medium are bet, a lottery is performed by operating a start lever. A plurality of (typically three) rows of symbol variation reels (display devices) having a plurality of symbols displayed on the surface are rotated.

  The advantage of the parrot machine is that when it is mixed with a pachinko machine in the hall, the game media (pachinko balls) to be managed can be integrated, and the management equipment for the game media can be simplified. .

  In the revolving game machines represented by the above-mentioned pachislot machines and parrot machines, a display window is attached to the front surface of the gaming machine main body, and a part of the design variable reel can be visually recognized from the display window. ing. Examples of the form of the visually recognized pattern include fluctuation and stop.

  The number of medals or pachinko balls bet corresponds to the number of effective lines in the symbol arrangement, and a game can be played with one (5 balls) bet (1 line) or MAX (3 or 15 balls) bet (5 lines). Done.

  This type of spinning machine is called a MAX bet-only machine. In a normal gaming state, the game is dedicated to a MAX bet, and is played exclusively for one (5 balls) bet after so-called jack-in.

  In addition to this MAX betting machine, in the normal gaming state, the player can play with any number of bets from 1 (5 balls, or 1 to 5 balls depending on the gaming specifications) to 3 (15 balls) as desired by the player. Some models are possible. Even in this type of game, after the jack-in described above, one game (5 balls, or 1 to 5 balls depending on game specifications) is played exclusively for betting.

  When the start lever is operated, an internal lottery is executed. At that time, the winning / exiting is determined, and when the winning symbol is assigned in the state where the internal lottery is won, the winning symbol is aligned. A dividend corresponding to the symbol can be obtained. In addition, there are a big role (big bonus, regular bonus) and a small role in the win. In the big role, the hit of the small role is dramatically increased, and it becomes possible to acquire many medals in a short period of time. In addition, if the major player wins the internal lottery, even if the winning symbol is not matched in the game, it will be effective after the next game, but the minor role will not be matched in the game when winning the internal lottery And the right to win disappears. In addition, it is possible that a small role (including replay) is won while a major role is won, or another big role is won. In addition, a game specification in which, when a predetermined period (the number of games, the passage of time) is exceeded during the election of a major player, the major player's right is invalidated, or when the predetermined procedure is not executed at a predetermined timing, the right of the major actor is extinguished. There is also.

  Here, in the case of giving a player some kind of privilege, for example, a benefit such as probability fluctuation, in a conventional swivel type gaming machine, a player intervention game is executed as appropriate, and the privilege is given based on the result. It has been proposed to decide whether or not.

  For example, Patent Document 1 discloses that hall personnel can change the setting of a lottery probability table by operating a key.

  Further, in Patent Document 2, when a specific condition such as a big role is fulfilled during a series of games, a player nominates one model from a plurality of models, and the appearance of the model and imaging means The degree of similarity with the photographed player's appearance is determined, and one winning probability table (lottery probability table) corresponding to the degree of game similarity with the model is selected from a plurality of winning probability tables and made valid. It is disclosed.

  In general, the conventional spinning machine including Patent Document 1 and Patent Document 2 includes a basic lottery probability table and a special lottery probability table, and each lottery probability table includes all winning combinations. (Big bonus, regular bonus, AT (assist time) right, small role, etc.) are included.

  The winning probability of each winning combination is different for each lottery probability table, and each winning combination changes with each change in the lottery probability table, and each gaming state has its characteristics. Yes.

It should be noted that the lottery probability table transition is generally performed after the end of the big bonus game or after the end of the game different from the normal game, such as after the AT right has expired, and when the player returns to the normal game, Can reduce the game motivation.

  However, as explained in the above prior art, since the lottery probability table corresponds to all winning combinations, the relative balance of the probabilities between the lottery probability tables and the composite balance are maintained well. This is necessary, and the degree of freedom for setting each lottery probability table is limited. For this reason, in an actual game, an extreme difference in gameability is difficult to occur, resulting in a loss of player's expectation.

  In addition, the setting of the lottery probability table within this limited range requires time for development and research for satisfying the player, which in turn promotes the delay in the development of the revolving game machine itself.

  In consideration of the above facts, the present invention can expand the degree of freedom of setting a plurality of kinds of lottery probability tables while maintaining good relative balance and synthetic balance of probabilities, and increasing the player's expectation, The purpose is to obtain a gaming machine capable of shortening the development period.

Invention according to claim 1, runs a lottery winning combination by starting operation of Yu technique's, the stop symbol after the variation of symbols, and a symbol variation display device for informing a per officer or out of the result of the lottery In the event that one of a plurality of winning combinations is won, and a game corresponding to the winning combination is prepared, a game that can obtain a predetermined payout is executed, A small combination in which game media corresponding to the combination of the combination is paid out, an RB combination that shifts to the game advantageous to the player, and a BB combination that shifts to the game more advantageous to the player than the RB combination are set. In the gaming machine, the lottery of the small role and the RB role among the small role, the RB role, and the BB role is executed, and the lottery of the BB role is not performed. and the probability table, the small , RB officers, and among the BB combination, the only lottery BB combination has been performed, stores the special game mode lottery probability table to be applied in the special game mode lottery is not performed in the Small Win and RB auditors, respectively And a lottery execution control means for selectively reading out the lottery probability table for the normal game mode and the lottery probability table for the special game mode from the lottery probability table storage means and executing the lottery. And the lottery execution control means reads the special game mode lottery probability table when the RB combination is won in the normal game mode and a game advantageous to the player by the RB combination ends. It is characterized by being possible.

  As described above, the present invention can expand the degree of freedom of setting a plurality of types of lottery probability tables that maintain a good relative balance and composite balance of probabilities and increase the player's expectation. It has an excellent effect that the period can be shortened.

  FIG. 1 shows a parrot machine 300 according to the present embodiment.

  The parrot machine 300 has the same game specifications as the pachislot machine, but the game medium of the pachislot machine is a medal, whereas the game medium of the parrot machine 300 is a pachinko ball P (see FIG. 2). It is.

Is transferred to the lower plate 328.

  When the three reels 350 </ b> A, 350 </ b> B, 350 </ b> C are driven, the symbol variation unit 316 can sequentially view the symbols recorded on the peripheral surface of the reel from the display window 314. The symbol stopped at the time becomes the basic stop symbol. In addition, this basic stop symbol is the case where the pachinko ball P for one game is thrown in, and the pachinko ball for three times can be thrown in a maximum of one game. In this case, it stops along the ascending and descending lines. The symbols that are stopped and the symbols that are stopped on the two diagonal lines are sequentially adopted as the combination stop symbols according to the number of pachinko balls P inserted.

  The stop buttons 356A, 356B, and 356C are provided below the symbol changing unit 316 and correspond to the reels 350A, 350B, and 350C. That is, the rotation of the corresponding reels 350A, 350B, and 350C can be stopped by operating the stop buttons 356A, 356B, and 356C by the player.

  Further, by operating (tilting) the start lever 20 provided on the left side of the stop buttons 356A, 356B, 356C, the reels 350A, 350B, 350C start to drive.

  The operation timing by the start lever 354 is a winning lottery timing, and the operation of the start lever 354 determines whether the internal controller hits or misses.

  Here, when the lottery is a win, the flag is established, and after that, when the win symbols are gathered, it becomes a win and is in a state advantageous to the player. In addition, there are a big bonus and a regular bonus, and the degree of the state advantageous to the player is different. Naturally, the big bonus is more advantageous than the regular bonus. Big bonuses and regular bonuses are collectively referred to as major players.

  Here, in this embodiment, as described above, the pachinko ball P is used as the game medium. The value of this pachinko ball is converted to a medal worth one game of a pachislot machine, and medal: pachinko ball = 1: 5. In this embodiment, the pachinko ball is based on the input of four or less pachinko balls P. The game has invalid specifications. Accordingly, in order to play a game for one game (one line bet) on the parrot machine 300, it is necessary to collect pachinko balls P in units of five balls.

  Therefore, the parrot machine 300 is provided with a pachinko ball collection device 100 (see FIG. 2). FIG. 2 shows a schematic view of a pachinko ball guide path from when a player rents a pachinko ball or receives a prize ball (payout) until it is collected by the pachinko ball collecting device 100 in units of five. Yes.

  As shown in FIG. 2, a pachinko ball P is guided from the payout device (not shown) to the ball payout path 102 and sent out to the tray 320.

  One end opening of the ball transfer path 104 communicating with the bottom plate 328 provided below the tray 320 communicates with the bottom of the tray 320. The ball transfer path 104 has a relatively large diameter. By opening a lid (not shown) provided at one end opening of the ball transfer path 104 of the receiving tray 320, a large number of pachinko balls P can be transferred to the lower plate 328 in a short time. Can be transferred to.

  Further, one end opening portion of the ball receiving path 106 for guiding the pachinko balls P from the tray 320 to the pachinko ball collecting apparatus 100 is communicated with the inner peripheral surface of the right side portion of the tray 320 in FIG.

  The ball receiving path 106 is an inclined path (slope) in which the tray 320 side is on the upper side and the pachinko ball collection device 100 side is on the lower side, and the pachinko balls P stored in the tray 320 are aligned in a row by their own weight. The pachinko ball collecting apparatus 100 is structured to flow.

  The pachinko ball collecting apparatus 100 includes a so-called revolver-type holder 112 having a plurality of (six in the present embodiment) accommodating portions 110 for stocking pachinko balls P in units of five inside the casing 108. Is provided.

  By collecting the pachinko balls (five) P accommodated in the accommodating portion 110 of the holder 112, a game for one bet becomes possible. That is, in the case of a max bet in a game with a maximum of five lines, the collection from the storage unit 110 is performed three times.

  The pachinko ball collecting apparatus 100 is connected to one end of a ball return path 130 for collecting the pachinko balls P after the ball receiving path 106 when the game is ended. Is communicated with the lower plate 328.

  FIG. 3 shows an outline of a control system that controls the progress of the game in the parrot machine 300.

  The control system of the parrot machine 300 according to the present embodiment is configured with a game main control circuit 150 as a center. The game main control circuit 150 stores a basic program relating to games, and the operation of each unit is controlled based on a command signal from the game main control circuit 150.

  The game main control circuit 150 is connected to a start / stop operation device 152, a bet button unit 154, a game information display device 156, an operation switch unit 158, and a reel drive device 160.

  The start / stop operation device 152 includes the aforementioned start lever 354 and stop buttons 356A, 356B, 356C. Further, the bet button unit 154 includes a 1 bet button 352A and a max bet button (a set bet number) 352B.

  Further, the game information display device 158 includes a display unit that displays messages such as game availability, game stop, replay, game start, and error, although not shown.

  Further, the operation switch unit 158 includes setting keys 353A, 353B, and 33C, and operations such as setting change, reset, calculation / power-on, bet number setting, and number of balls per bet can be performed. ing.

  The reel driving device 160 includes the above-described reels 350A, 350B, and 350C, and further, reel motors 162A, 162B, and 162C (see FIG. 4) for driving the reels 350A, 350B, and 350C (see FIG. 4) and the reels 350A, Sensors 164A, 164B, and 164C for detecting the positions of 350B and 350C are configured.

  Further, the game main control circuit 150 outputs information indicating the progress of the game to the hall computer via a board external terminal (not shown).

  On the other hand, a game sub control circuit 166 and an effect sub control circuit 168 are connected to the game main control circuit 150.

  The game sub-control circuit 166 is connected to a game medium take-in device 170 and a game medium payout device 172, and controls the take-in and pay-out of pachinko balls P, which are game media, respectively.

  In addition, an information display device 174 is connected to the game sub-control circuit 166 so that the payout number of game media (pachinko balls P) is displayed on a display unit (not shown) (located at the lower front portion of the display panel unit 312). To control. The information display device 174 controls to display the number of pachinko balls P inserted (in some cases, the number of bets in units of 5), the number of credits (credits), the number of payouts of the winning combination, and the like.

  The effect sub-control circuit 168 is constituted by an award table display device 176 for displaying the number of payouts of each winning combination on the display panel 312 and the like, a liquid crystal display device, etc. A device 178 and a sound effect generator 180 for controlling output from a speaker (not shown) are connected.

  In the above-mentioned player main control circuit 150, in synchronization with the operation of the start lever 354, the lottery control outside and outside and the drive start control of the reels 350A, 350B, 350C are performed, and the flag is established when the lottery result is a win. Then, when the winning symbols are aligned by the subsequent operation of the stop buttons 356A, 356B, 356C, the hitting right is exercised and the player is in an advantageous state.

  Here, in the game main control circuit 150, when the stop operation is performed by the stop buttons 356A, 356B, and 356C, the slip control of a predetermined number of frames is executed according to whether the internal lottery is successful or not.

  That is, when the stop button 356A, 356B, 356C is operated at the stop timing of the symbol that stops only in the case of winning when the internal lottery is off, the stop position is shifted in order to intentionally avoid the stop at this symbol. (Kicking off).

  On the other hand, when the internal lottery is won, if the winning symbol is located in a range where the symbol does not stop at the stop timing operated by the player, the predetermined number of frames (for example, 4) If there is a winning symbol in the frame (top), it stops so as to come out of this symbol. The invention of claim 1 shifts (draws), and if there is a winning symbol at a position deviating from the predetermined number of frames, the predetermined frame is detected. Because it is a specification that can not pull in winning symbols beyond the number, the above kicking processing, in other words, a symbol that is irrelevant to the corresponding role (missing symbol), another winning symbol, so as not to cause inconvenience in the type of winning symbol ) Is applied.

  By performing the above kick-off control and pull-in control (collectively, slip control), it is possible to have consistency with the lottery result, and even if the stop operation timing is slightly shifted, it is possible to align the winning symbols. .

  Here, in this embodiment, when the winning combination is won as described above, the game mode may be changed. As the game mode, a normal game mode and a special game mode are set.

  The normal mode is a mode in which a lottery of a small role (including replay) and RB (regular bonus) is executed, and a BB (big bonus) lottery is not performed.

  On the other hand, the special game mode is a mode in which a lottery for only BB is executed.

  The game mode switching (transition) condition depends on whether or not a mode transition lottery is performed when a winning combination (small role, big bonus, regular bonus) is won and a dividend or right exercise ends.

  FIGS. 4A and 4B show schematic diagrams of a lottery probability table applied in each game mode. Note that the length of the lot in the lottery probability table indicates a random value, for example, a number from 0 to 65000 is repeatedly counted, and the number is determined according to the random value acquired when the start lever 354 is operated. Judgment is made.

  As shown in FIG. 4 (A), the lottery probability table in the normal mode occupies all random numbers according to the four types of small roles (excluding replay), replay, RB, and missed in which the winning combination is divided into two groups. The length of each band corresponds to the amount of random values it occupies.

  On the other hand, as shown in FIG. 4 (B), the lottery probability table in the special mode occupies all random numbers according to two types of BB in which the winning combination is divided into two groups and off, and the length of each band Corresponds to the amount of random values occupied.

  As described above, in the normal game mode, it is only necessary to set the lottery probability table considering only the relative balance between the small role (including replay) and RB. In the special game mode, only the BB is set. It may be set in consideration of the balance with the lottery probability table.

  In other words, conventionally, as shown in FIG. 4 (C), it is necessary to distribute in a well-balanced manner within one band (random number value) of all winning roles, taking into consideration the design ball-out rate. However, in the present embodiment, it was not possible to break a game specification that does not have sharpness (no interesting taste) in a short period of time, but in this embodiment, as shown in FIGS. (In this embodiment, two types of lottery random number tables) are prepared, and each mode is changed by lottery, thereby maintaining the overall (multiple lottery random number table) ball-out rates and a short period of time. It becomes possible to increase the possibility that BB wins by concentrating on.

  FIG. 5 shows a functional block diagram relating to the transition control to the special game mode / normal game mode in the game main control circuit 150.

  The start lever 354 is connected to the lottery unit 10, and the lottery unit 10 executes the lottery at the time of operating the start lever 354 as described above.

  The lottery result by the lottery unit 10 is sent to the lottery result determination unit 12 to determine the lottery result. The lottery result determination unit 12 is connected to the reel drive control command output unit 14. The reel drive control command output unit 14 is also connected to the start lever 354. When the start lever 354 is operated, a command is output to control the driving of the reels 350A, 350B, 350C, and the reel drive control unit 16 is controlled. The reel motors 162A, 162B, and 162C are controlled via the motors to drive the reels 350A, 350B, and 350C.

  The reels 350A, 350B, and 350C are provided with position detection sensors 164A, 164B, and 164C, respectively, for detecting a rotation position (for example, one pulse signal per rotation and a stopped pattern are recognized). Is sent to the stop position detector 18.

  The reel drive control command output unit 14 is connected to the stop buttons 356A, 356B, 356C, and generates a command to stop driving the reels 350A, 350B, 350C when the stop buttons 356A, 356B, 356C are operated. However, at this time, a command is generated in a state in which the kicking control and the pull-in control (generally referred to as slip control) are taken into account, and the reel drive control unit 16 executes the slip control.

  As a result, the reels 350A, 350B, and 350C are stopped based on the operation of the stop buttons 356A, 356B, and 356C so that a predetermined symbol is displayed in a state in which slip control is added.

  The stop position (stop symbol) detected by the stop position detector 18 is sent to the winning / exit determining unit 20, where it is determined whether or not the symbols matching the lottery result have been prepared, and the determination result is used as a game sub game. The data is sent to the control circuit 166. As a result, in the case of a small combination, the payout pachinko ball P is paid out.

  In addition, the determination result of the winning / exit determining unit 20 is sent to the gaming state recognition unit 22 to recognize the gaming state (the type of the combination, the dividend or the status of exercising the rights, etc.). At the time, in the case of RB or BB, the mode transition lottery instruction signal is sent to the mode transition lottery unit 30 when the exercise of rights is completed.

  The mode transition lottery unit 30 executes a lottery to determine whether or not to change the mode with a predetermined probability. When the mode transition is performed as a result of the lottery, a mode transition instruction signal is sent to the mode transition execution unit 32.

  A lottery probability table memory 34 is connected to the mode transition execution unit 32. In the lottery probability table 34, the normal game mode lottery probability table 34A and the special game mode lottery probability table 34B shown in FIGS. 4A and 4B are respectively stored.

  The mode transition executing unit 32 alternately reads out the normal game mode lottery probability table 34A or the special game mode lottery probability table 34B every time the mode transition instruction signal is input, and rewrites one of the lottery probability table data. It is sent to the execution lottery probability table memory 36 together with the signal.

  Thus, the lottery probability table data read out by the mode transition execution unit 32 is always stored in the execution lottery probability table memory 36.

  In the lottery unit 10, the lottery is executed based on the lottery probability table currently stored in the execution lottery probability table memory 36.

The operation of this embodiment will be described below.
(Game flow)
The game procedure is as follows. First, a pachinko ball P has been inserted, and a one-bet button 352A (one-line game) that is a one-time game, a max-bet button 352B (five-line game) that is a three-time game. When the betting by) is completed, the start lever 354 is operated. At this time, a winning / losing lottery is made, and in the case of winning, a flag is established in an internal control manner. If the flag has already been established, the lottery is not executed.

  After the start lever 354 is operated, the reels 350A, 350B, and 350C start to drive.

  The player operates the stop buttons 356A, 356B, and 356C to stop the rotation of the reels 350A, 350B, and 350C. However, when the flag is established, the player wins the winning symbol by the accurate timing of pressing. Can be stopped. In addition, a slight shift in the stop operation timing is corrected by “retraction control”. On the other hand, if the flag is not established, “kicking control” is executed to stop the rotation of the reels 350A, 350B, and 350C even if the flag is pushed, so that the winning symbol is not stopped.

  When the display symbols of the reels 350A, 350B, and 350C stopped by the stop operation are aligned with the winning symbols, bonus game control is executed.

  Here, in the present embodiment, a normal game mode and a special game mode are set as game modes, the winning combinations are classified into two groups, and each group is assigned to the game mode. That is, in the normal game mode, the lottery is executed by the lottery probability table corresponding to the small role, replay, and RB, and in the special game mode, the lottery is executed by the lottery probability table corresponding to BB.

  The transition to the game mode is performed after a winning combination (after paying for a small role, after exercising the right for a bonus game), and a transition is made based on the lottery result of this mode shifting lottery. The

  FIG. 6 shows a flowchart for the game mode switching control between the normal game mode and the special game mode.

  In step 400, the current game mode is confirmed, and in the case of the normal game mode, the routine proceeds to step 402, where a lottery of RBs and small roles (including replay) is executed. That is, since the lottery probability table memory 36 for execution is in a state where the lottery probability table shown in FIG. 4A is stored, the BB lottery is not substantially executed.

  In the next step 404, it is determined whether the RB has been won (whether the internal lottery has been won and the symbols have been prepared). If an affirmative determination is made, the process proceeds to step 406, the RB game is executed, and the process proceeds to step 412. . If the determination at step 406 is negative, the process proceeds to step 408.

  In step 408, it is determined whether a small role (including replay) has been won (whether the internal lottery has been won and the symbols have been prepared). If an affirmative determination is made, the process proceeds to step 410 to execute a payout process. Move to 412. If the determination in step 408 is negative, this routine ends and the current game mode is maintained.

  In step 412, the mode transition lottery is executed, and in the next step 414, it is determined whether or not the mode transition lottery has been won.

  If it is determined that the winning is made in this step 414 (affirmative determination), the process proceeds to step 416, where the mode transition execution unit 32 reads the special game lottery probability table 34B from the lottery probability table 34 and executes the lottery probability table memory for execution. The data in 36 is rewritten. Note that if a negative determination (decision) is made in step 414, this routine ends and the current game mode is maintained.

  In the next step 418, the game mode is set to the special game mode, and this routine ends.

  On the other hand, if it is determined in step 400 that the game mode is the special game mode, the process proceeds to step 420.

  In step 420, a BB lottery is executed. That is, since the lottery probability table memory 36 for execution is in a state where the lottery probability table shown in FIG. 4B is stored, the lottery of the RB and the small role (including replay) is not substantially executed. become.

  In the next step 422, it is determined whether the BB has been won (whether the internal lottery has been won and the symbols have been prepared). If an affirmative determination is made, the process proceeds to step 424, the BB game is executed, and the process proceeds to step 426. . If the determination at step 422 is negative, this routine ends and the current game mode is maintained.

  In step 426, the mode transition lottery is executed, and in the next step 428, it is determined whether or not the mode transition lottery has been won.

  If it is determined that the winning is made in this step 428 (affirmative determination), the process proceeds to step 430 and the mode transition executing unit 32 reads the normal game lottery probability table 34A from the lottery probability table 34 and executes the lottery probability table memory for execution. The data in 36 is rewritten. If a negative determination is made in step 428 (decision), this routine ends and the current game mode is maintained.

  In the next step 432, the game mode is set to the normal game mode, and this routine ends.

  Thus, in the present embodiment, the winning combinations are classified into two groups in advance, and the normal game mode lottery probability table 34A and the special game mode lottery probability table 34B are prepared corresponding to each group. The two types of lottery probability tables are subjected to mode transition lottery at a predetermined opportunity (after paying for a small role, after exercising rights for a bonus game), and when winning, the game mode is shifted. Thus, for example, in the special game mode, only the BB lottery is executed, so that the probability of winning the BB in a short time can be increased. In addition, the setting of the mode transition lottery probability can maintain the conventional starting probability, so the designed starting probability can be maintained over a long span, and the game can be sharpened over a short span. Can increase the willingness to play, and the store's sales policy can be easily established.

In the present embodiment, the single lottery probability table (see FIG. 4C), which has been conventionally one, is divided into two types (see FIGS. 4A and 4B), and lottery only for BB is performed. Although the period is set as the special game mode, the lottery regarding AT (assist time) may be taken into consideration.
That is, FIG. 7 (D) shows a lottery probability table of conventional AT-equipped models, which are classified into three groups of FIGS. 7 (A) to (C), and drawn by each mode lottery. Play a game under the probability table. In this case, if all of FIG. 7C are used as small roles (AT), the payout per game can be doubled or more than the conventional one.

  In the present embodiment, the winning combination is not overlapped between the classified lottery probability tables, and the calculation of the design of the pitch rate is simplified. The current mode may be made difficult to understand by duplicating with probability, or may be duplicated so as to form a BB winning chance in any mode.

  In the above embodiment, the parrot machine 300 using the pachinko ball P as a game medium has been described as an example of the game machine, but the present invention can also be applied to a general pachislot machine using a medal as a game medium. Note that the game specifications of the pachislot machine and the parrot machine 300 are almost the same, and only the game media to be inserted when betting is different.
