Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine having a variable display device for variably displaying various symbols, and having a prize when a predetermined symbol is stopped and displayed on a prize line.

[0002]

2. Description of the Related Art Conventionally, in a general slot machine, 1
When the start lever is operated by the player after three or more medals are inserted, three reels constituting the variable display device rotate. As shown in FIG. 22A, a symbol 94 represented by a circle is provided on the outer peripheral surface of each of the reels 91, 92, 93.
Are drawn, and the symbols 94 are observed three by three through windows formed in the front panel. On the front panel,
A winning line L1 passing through each symbol 94 at the center of each reel 91-93, a winning line L2A passing through each symbol 94 above each reel 91-93, and a winning line L2B passing through each symbol 94 below each reel 91-93. , Each reel 91.92.9
The winning line L passing through the upper, middle and lower symbols 94 of 3
3A, and the lower, center,
Five pay lines L3B, which pass through each of the upper symbols 94, are shown.

When one medal is inserted into the slot machine, the pay line L1 is activated, and when two medals are inserted, the pay lines L1, L2A, L2B are activated, and three medals are inserted. Then, all the winning lines L1, L
2A, L2B, L3A, L3B are activated. Since the lottery winning probability is usually set to be the highest when betting three slot machines, the player normally inserts three medals into the slot machine and activates all the winning lines to play the game.

[0004] The rotation of each of the reels 91 to 93 is stopped by the player's operation of the stop button. At this time, when a predetermined combination of symbols is stopped and displayed on the activated winning line, a prize is generated, and the number of medals according to the winning mode is paid out to the player. The winning mode is determined by a lottery inside the machine. This determination is made according to which section of the winning probability table the random number selected by lottery belongs to. That is, the winning mode of the table section to which the random number belongs belongs to the winning mode determined by the lottery inside the machine, and the hit request flag corresponding to the winning mode is set.

[0005] A general winning mode in a slot machine occurs, for example, when the same symbols arranged on three reels are stopped on the winning line. In this case, the stop button must be operated for each reel so that the symbols to be aligned stop on the pay line. At the beginning of the game, such an operation is not troublesome, but as the number of games increases and the player accumulates fatigue, the stop button operation for each reel tends to be troublesome There is. Also, in terms of operation technique, all three symbols must be stopped on one winning line, which is difficult for beginners. Therefore, a prize mode in which a prize is generated only by stopping one single symbol on the prize line has been devised.

[0006] As one type of prize-winning mode in which a prize is generated with a single symbol, there are hitherto small win prize modes of cherry called "two cherries" and "four cherries". "Two cherries" are as shown in FIG.
This is a winning mode that occurs when one symbol “Cherry” is stopped and displayed on the activated winning line L1 of the first reel 91, and the number of payout medals is two. "4 cherry" is a winning mode that is generated when one symbol "cherry" is stopped and displayed at the intersection of the activated winning lines L2A and L3A of the first reel 91, as shown in FIG. The number of payout medals at the time of betting three is four.
This "4 cherry" is generated even when one symbol "cherry" is stopped and displayed at the intersection of the activated pay lines L2B and L3B of the first reel 91, as shown in FIG.

The stop positions of the rotating reels 91 to 93 are controlled such that a symbol corresponding to the type of the hit request flag is stopped and displayed on the display window. That is, when the stop button is operated, the symbol displayed in the display window is not the symbol corresponding to the winning mode, but the symbol corresponding to the winning mode exists in, for example, four frames of symbols displayed subsequent to the display window. In this case, reel control for drawing in the symbol is performed so that the symbol corresponding to the winning mode is stopped and displayed in the display window.

However, in a slot machine called a CT (challenge time) machine, when a certain condition is satisfied, for example, the stop display control of the symbol in the small hit prize mode is performed for some reels, for example, the first reel 91. The stop position of the reel 91 that has been suspended and spinning is determined only according to the timing of the operation of the stop button by the player. Even in the CT period in which the stop display control is interrupted, the drawing control of the symbols for four frames is performed on the other reels, for example, the second reel 92 and the third reel 93. For this reason, with respect to the other reels 92 and 93 for which the stop display control is not interrupted, even if the player operates the stop button at a timing earlier by up to four frames, the symbol of the winning combination is drawn in and displayed on the window. Is done.

An example of such a CT machine is disclosed in Japanese Patent Application Laid-Open No. 1-2388888.

[0010]

However, in the above-mentioned conventional gaming machine, the small winning prize mode of the cherry depends on the stop position of the cherry, and as described above, the two-prize "two-cherry" and the four-prize Divided "4 cherry"
And only two types occur. For this reason, in a general slot machine and a slot machine called a CT machine, there are restrictions on the types of small hit prize modes that can be aimed at by a player. In other words, the taste of gaming machines was not enough.

In a slot machine called a CT machine, a CT period advantageous to a skilled player is, for example, 1
The process ends if either one of the conditions of 50 games has been completed or 200 medals has been paid out. In each game during this CT period, the lottery of the big bonus (BB) game, which is a big hit prize mode, and the regular bonus (RB) game, which is a middle hit prize mode, is still executed. These BB games and RB
In games, you can usually get a lot of medals.

For this reason, during the CT period, the player simply waits for the winning mode of the BB game or the RB game to be randomly selected by the internal lottery of the machine without reducing the number of medals in hand. To this end, the player keeps the number of medals paid out to 200,
Play more games as close as possible to zero times,
The game is advanced so that the lottery inside the machine is performed more times.

Therefore, it is necessary for the player to finely adjust the number of obtained medals during the CT period according to the game state. In the above-mentioned conventional gaming machine, in the cherry small win prize mode, two medals are obtained as described above. Alternatively, only two kinds of payouts of four can be selected. For this reason, if a “two-cherry” winning mode is generated by a pushing operation while playing a game with three bets, the number of medals in hand is calculated by the formula 2-3 = −1.
Reduces one sheet. On the other hand, when the player plays the game with three bets and generates the “four-cherry” prize mode by a pushing operation, the number of medals in hand can be calculated by Equation 4-
With 3 = 1, there is only one net increase.

Here, the pressing operation means an operation in which the player presses the stop button while watching the reel symbol appearing in the observation window while measuring the timing at which a desired symbol appears in the observation window. are doing.

That is, for example, when the number of medals acquired is still small despite the number of remaining games being reduced,
When the number of medals to be acquired must be increased in a hurry with a small number of games, “one net increase” may cause a case where the prescribed number of games ends before the prescribed number of medals is acquired. Therefore, conversely, 1
It is conceivable to increase the number of medals obtained by winning a prize. For example, if the above-mentioned symbol “Cherry” is awarded with six cards, if the symbol “Cherry” is stopped in the upper or lower row of the first reel, the payout becomes “12-cherry” with a twelve-card payout. It is possible to increase the number of obtained medals. However, in this case, the number of medals obtained will increase greatly each time a prize is won, and conversely, the specified number of medals obtained will be satisfied before reaching the specified number of games, and the CT game will end.

That is, in the above-mentioned conventional gaming machine, the range of the number of obtained medals that can be adjusted during the CT period according to the small winning prize mode of the cherry tree is narrow or too wide. Therefore, also from this viewpoint, the above-described conventional gaming machine, which has a limitation on the types of winning modes to be generated, lacks the taste, and the player cannot fully enjoy the interest of the CT machine.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and a variable display device for variably displaying various symbols in a plurality of columns is provided with a symbol stop based on a random number lottery result. When a predetermined symbol is stopped and displayed on the winning line, a prize is generated, and in a gaming machine for awarding a payout to a player, a plurality of predetermined symbols constituting a prize alone are generated and generated by a predetermined symbol. Each winning mode is characterized by different payouts and being established simultaneously.

According to this configuration, a plurality of symbols each independently constituting a prize mode with a different payout are stopped and displayed in various combinations on the prize line, so that various combinations of prize modes occur and various Is paid out to the player.

When predetermined symbols are adjacent to each other and combined to form a new symbol, the new symbol becomes conspicuous by occupying a large symbol area. It becomes easier for the player to visually recognize the variable display.

17 and 18 are provided. The credit / payout (PLAY CREDIT / PAY OUT) of the medal can be switched by operating the push button of the C / P switch 14.

By operating the start lever 15,
The rotation of the reels 3, 4, and 5 starts simultaneously. The stop buttons 16, 17, 18 are variable display stop means 72 (see FIG. 9) for stopping the rotation display of the reels 3, 4, 5 for each row.
, And are arranged corresponding to the reels 3, 4, and 5. When the rotation speed of each of the reels 3 to 5 reaches a certain speed, the operation of each of the stop buttons 16 to 18 is enabled,
Each of the stop buttons 16 to 18 stops the rotation of each of the reels 3 to 5 in accordance with a push button operation of the player.

In the slot machine according to the present embodiment, the first stop reel that is operated to stop first and the second stop reel that is operated next to stop are controlled by the stop display control means 73 described later during the CT period. The stop display control is interrupted for a specific winning mode, for example, a small winning mode. That is, when a small hit prize occurs during the CT period, for example, the first stop reel and the second stop reel are immediately stopped only in accordance with the operation timing of the stop buttons 16 to 18 by the player. On the other hand, for the third stop reel that is stopped last, the stop display control unit 73 performs stop display control even during the CT period. That is, the third stop reel is controlled so as to stop and display, for example, a symbol corresponding to a small winning prize combination which can be generated by a combination of symbols stopped and displayed by the first stop reel and the second stop reel.

Further, a sound transmission hole 19 and a medal tray 20 are provided in a lower part of the front of the slot machine 1. The sound transmission hole 19 is for outputting sound generated from a speaker housed inside the device to the outside. The medal tray 20 stores medals paid out from a medal payout exit 21.
In addition, a payout display unit 22 is provided on the front upper portion of the slot machine 1 to indicate how many medals are paid out for each winning.

A liquid crystal display unit 24 is provided on the front panel 2 on the right of each of the reels 3, 4, and 5. The liquid crystal display unit 24 displays the rotation of each of the reels 3, 4, and 5,
It is a display device that displays a game history and performs effects during a bonus game.

FIG. 6 shows the contents of the payout display section 22, and shows payout combination symbols and the number of payout medals in each winning mode. That is, the big bonus (BB) game in the jackpot winning mode is the first reel 3,
This occurs when three symbols “open white 7” are aligned on the activated pay line of the second reel 4 and the third reel 5, indicating that the number of payout medals is 15 during a general game. Further, the regular bonus (RB) game in the medium winning prize mode occurs when three symbols “black 7” are aligned on the activated prize line of each of the reels 3 to 5, and the number of payout medals is reduced during a general game. This indicates that there are 15 sheets.

In addition, the hat in the small hit prize mode has three symbols "hat" on the activated prize line of each reel 3-5.
This occurs when all the coins are collected, and indicates that the number of payout medals is seven during the general game and nine during the BB operation, that is, during the BB game. Further, the cactus in the small hit prize mode is generated when three symbols “cactus” are aligned on the activated prize line of each reel 3 to 5, and the number of payout medals is
This indicates that there are three cards during a general game and three during BB operation.

The upper half sun of the small hit prize mode is generated when one symbol "the upper half sun" is aligned on the activated prize line of the first reel 3, and the number of payout medals is reduced during a general game. One sheet is shown during the BB operation. In addition, the lower half sun of the small hit prize mode is the first sun.
Symbol "Lower half sun" on the activated prize line of reel 3
Is generated, indicating that the number of payout medals is seven during the general game and seven during the BB operation. The upper and lower adjacent symbols “upper half sun” and “lower half sun” that combine to form a new symbol “sun” independently constitute a winning mode with a different payout.

The replay (replay, RP) is indicated by the symbol "ancient bird" on the activated prize line of each reel 3-5.
Is generated when three medals are collected, indicating that the number of payout medals is not nine during the general game but nine during the BB operation.

FIG. 7 shows a circuit configuration including a control unit for controlling a game processing operation in the slot machine 1 of the present embodiment and a peripheral device (actuator) electrically connected to the control unit.

The control section has a microcomputer (hereinafter referred to as "microcomputer") 30 as a main component, and further includes a circuit for random number sampling. The microcomputer 30 includes a CPU 31 for performing a control operation according to a preset program, and a ROM 32 and a RAM 33 as storage means. The CPU 31 includes a clock pulse generating circuit 34 and a frequency divider 35 for generating a reference clock pulse, a random number generator 36 for generating a random number within a certain range, and a random number sampling circuit 37 for extracting an arbitrary random number from the generated random numbers. Is connected.

The main actuators whose operations are controlled by control signals from the microcomputer 30 include reels 3 and
Stepping motors 55 for rotating 4 and 5, hopper 38 for storing medals, liquid crystal display 24, speaker 3
9 and a back lamp 57. These are a motor drive circuit 40, a hopper drive circuit 41, a display drive circuit 42, a speaker drive circuit 43, and a lamp drive circuit 48, respectively.
Driven by These drive circuits 40 to 43, 48
Is connected to the CPU 31 via the I / O port of the microcomputer 30. Each of the stepping motors 55 is excited in one or two phases by the motor drive circuit 40, and rotates once when a drive signal of 400 pulses is supplied.

The main input signal generating means for generating an input signal necessary for the microcomputer 30 to generate a control signal includes a start switch 15S for detecting the operation of the start lever 15 and a medal insertion port 9 The inserted medal sensor 9S for detecting the inserted medal, and the C /
There is a P switch 14. There is also a photo sensor 59, and a reel position detection circuit 44 that receives the output pulse signal from the photo sensor 59 and detects the rotational position of each of the reels 3, 4, and 5.

The photo sensor 59 detects the shielding plate 60 every time the reels 3, 4 and 5 make one rotation, and generates a reset pulse. This reset pulse is applied to the reel position detection circuit 44.
Is given to the CPU 31 via the. In the RAM 33,
For each of the reels 3 to 5, a count value corresponding to a rotation position within the range of one rotation is stored, and upon receiving a reset pulse, the CPU 31 clears the count value formed in the RAM 33 to "0". . By this clear processing, the movement display of each symbol and each stepping motor 5 are displayed.
The deviation that occurs between the rotations of rotation No. 5 and rotation No. 5 is eliminated for each rotation.

Further, as the input signal generating means,
Reel stop signal circuit 45 and payout completion signal generation circuit 4
There are six. The reel stop signal circuit 45 includes a stop button 1
When 6, 17, 18 are pressed, the corresponding reel 3,
Generate a signal to stop 4,5. Further, the medal detection unit 47 counts the number of medals paid out from the hopper 38, and the payout completion signal generation circuit 46 converts the medal count value actually paid out inputted from the medal detection unit 47 into predetermined payout number data. When it has reached, a signal notifying the completion of the medal payout is output to the CPU 31.

The ROM 32 stores, as a sequence program, a procedure of a game process executed by the slot machine 1, and stores a winning probability table, a symbol table, a winning symbol combination table, and the like, respectively. I have.

The winning probability table is stored in the sampling circuit 3
7 is used to divide the random numbers extracted in 7 into the respective winning modes, and stores data for partitioning a certain range of random numbers generated by the random number generator 36 into the respective winning modes. Such a winning probability table is configured, for example, as shown in FIG. A1 to a3, b1 to b3, c1 to c in FIG.
3, d1 to d3, e1 to e3, f1 to f3, g1 to g3
Is preset numerical data, and is used when dividing the random number extracted by the sampling circuit 37 into each winning mode. This data is “a1 to g1” when the number of inserted medals is one, “a2 to g2” when the number is two, and 3
In the case of sheets, a combination of the numerical values of “a3 to g3” is used.

These numerical values are usually expressed as “a <b <c <d <e <
f <g ”and the extracted random number is d
If the value is less than a, a small hit prize (small hit) is obtained. In this case, if the value is less than a, a request flag for “lower half sun” is set. When the value is b or more and less than c, a request flag for “cactus” is raised, and when the value is c or more and less than d, a request flag for “hat” is raised. If the extracted random number value is equal to or more than d and less than e, a "re-game" request flag is set. If the extracted random number value is equal to or more than e and less than f, a medium hit prize (medium hit) is set and a request flag is set for “RB”. If the extracted random number value is equal to or more than f and less than g, a big hit prize ( A big hit) and a request flag for “BB” is set. If the value is equal to or larger than g, a request flag for "losing" without winning is set.

That is, the winning mode is determined by which numerical range one sampled random number value belongs to, and is represented by a hit request flag. here,
The random number generator 36, the sampling circuit 37, the winning probability table, and the microcomputer 30 constitute a winning mode determining means 74 (see FIG. 9). This winning mode determination means 74
Determines the winning mode of the game based on the random number 75 selected as described above, and sets a hit request flag according to the determined winning mode.

The symbol table is conceptually shown in FIG. The symbol table is for associating the rotation positions of the reels 3 to 5 with the symbols, and represents a symbol row by symbols. In this symbol table, symbol codes corresponding to the code numbers are stored for each of the reels 3 to 5. The code numbers are sequentially assigned at a constant rotation pitch of each of the reels 3 to 5 based on the rotation position at which the reset pulse is generated.
The symbol code indicates a symbol provided corresponding to each code number.

In the winning symbol combination table,
The symbol code of each winning symbol combination, the number of winning medals, and the symbol code of a symbol combination constituting a “reach eye” that suggests to the player that the flag for the occurrence of a specific game has been established, as shown in the payout display section 22. And a winning determination code representing each winning. This winning symbol combination table is referred to at the time of stop control of the first reel 3, the second reel 4, and the third reel 5, and when performing a winning confirmation after stopping all the reels.

Reel position detection circuit 44, reel stop signal circuit 45, motor drive circuit 40, stepping motor 5
5 and the microcomputer 30 are provided with a stop display control unit 73 for causing the variable display device 71 to stop display a symbol corresponding to the winning request flag set by the winning mode determination unit 74.
(See FIG. 9). That is, the stop display control means 73 detects the operation timing of the variable display stop means 72 by the reel stop signal circuit 45, and the symbol displayed on the activated pay line at this operation timing is indicated by the hit request flag. If, for example, a symbol corresponding to the winning mode exists among the symbols of, for example, four frames displayed on the activated winning line instead of the symbol corresponding to the mode, this symbol is activated in the display windows 6 to 8. Control to pull in on the line. At this time, the motor drive circuit 40 and the stepping motor 55 are controlled by the microcomputer 30 while the types of the symbols displayed in the display windows 6 to 8 are grasped by the reel position detection circuit 44,
The rotation of the reels 3 to 5 is controlled.

The microcomputer 30 also comprises a flag invalidating means 76 and a stop control suspending means 77 shown in FIG. When a specific condition is satisfied, that is, when a CT period is reached after winning a random number lottery described later, the flag invalidating means 76 sets a specific hit request flag set by the winning mode determination means 74. Then, the winning request flag of the small winning prize mode is invalidated. This invalidation is performed in steps 154 and 15 in the flowchart of FIG.
By the processing of No. 5, the winning request flag of the small winning prize mode is set as a loss flag. Therefore, during the CT period, even if the small winning prize is determined by the prize mode determining means 74, the winning request flag of the small winning prize is invalidated, which is equivalent to that the lottery of the small winning prize is not performed. That is, the lottery is performed only for the bonus winning (BB, RB winning) and the replay.

The stop control suspending means 77 operates according to a predetermined condition when the above specific condition is satisfied.
The stop display control of the symbol corresponding to the invalidated specific hit request flag is interrupted for the first stop reel and the second stop reel. In the present embodiment, the predetermined condition is that until a predetermined number of games are played or a predetermined number of medals are paid out, whichever comes first, whichever comes first. And the stop display control means 7 until the condition is satisfied.
3 is stopped. Specifically, the CT game is continuously performed for only 150 games after the end of the BB game, but the CT game ends when 200 medals are paid out to the player even within the 150 games.

Next, the operation of the gaming machine controlled by the microcomputer 30 in this embodiment will be described.

FIGS. 11 and 12 are flowcharts showing the outline of this game processing.

First, the CPU 3 determines whether or not a replay (replay) has occurred as a result of the previous game and there is automatic medal insertion.
1 (see FIG. 11, step 101). If there is this automatic insertion, the game medals corresponding to the insertion request are then automatically inserted (step 102). On the other hand, if there is no automatic insertion, the player next inserts medals into the medal insertion slot 9 and waits for a detection signal to be input from the medal sensor 9S (step 103).
Or, BET switches 10, 11, 1 depending on the player.
2 is operated and waits for signals from these switches to be input. Up to three medals can be inserted during a general game, and one medal can be inserted in a bonus game during a BB game or an RB game.

Next, by operating the start lever 15,
It is determined whether or not a start signal has been input from the start switch 15S (step 104). If this determination is "YES", it is next determined whether 4.1 seconds have elapsed since the previous game (step 105). 4.
If one second has not elapsed, the waiting time for starting the game is consumed until 4.1 seconds have elapsed (step 106).
After 4.1 seconds, a winning determination is made by the winning mode determining means. That is, a random number for lottery generated by the random number generator 36 is extracted by the sampling circuit 37 (step 107), and a probability lottery process is performed (step 108).

This probability lottery process is performed in accordance with FIG. 13 and FIG.
Is performed according to the flowchart shown in FIG. 7, and it is determined that one random number value specified by the sampling circuit 37 belongs to a winning group in the winning probability table (see FIG. 8). That is, first, the accumulation area of the probability lottery values secured in the RAM 33 is cleared (FIG. 13, step 131). Next, the winning number 1 is set in the winning number storage area in the RAM 33 (step 132). This winning number is shown in FIG.
The winning number 1 corresponds to the winning of the lower half sun.

In the table, the number of lotteries, the lottery combinations, and the order are shown for each game state of normal game, inside BB, RB, normal game during BB, and CT period. In the game state of the general game, the number of lotteries is expressed as seven, and the lower half sun, the upper half sun, cactus, hat, re-game, R
B, lottery combinations of CT-free BB and CT-added BB and their order 1 to 8 are shown. The above winning numbers correspond to this order, and order 1 is the winning number 1. In addition, in each of the game states of the BB and RB internal hits and the general game during the BB, the number of lotteries is expressed as 5 times, respectively.
The lottery combinations excluding B and the order are shown. Also, CT
Since the period belongs to the general game state category, the same number of lotteries, lottery combinations and orders as those of the general game in the leftmost column are shown.
However, since the small winning prize during the CT period is invalidated, it is deleted from the lottery combinations of the order 1 to 4.

Next, the number of lotteries during the BB regular game (5
Is set in the lottery number storage area of the RAM 33 (step 133). Next, a game state flag described later is referred to to determine whether the current game state is the BB operation, that is, whether the current game state is just the BB game state (step 134). If the BB operation is being performed, the process proceeds to step 138 described below. If the BB operation is not being performed, it is next determined whether or not the BB or RB is hitting inside (step 135). If the inside of the BB or RB is being hit, the number of lotteries per BB or RB inside hit (5 times) is set in the lottery number storage area (step 136). If the inside of the BB or RB is not hit, The number of lotteries during the normal game (seven times) is set in the lottery number storage area (step 137). At the time of the normal game here, a CT period is included.

Next, the number of medals inserted into the machine is checked (step 138), and the probability lottery data for one medal is set in the probability lottery data storage area of the RAM 33 (step 139). That is, the probability lottery data a1 to g1 when the number of inserted medals is one, which is shown at the top of the winning probability table in FIG. 8, are set. Next, it is determined whether or not the number of inserted medals is one (step 140). If the number is one, the process proceeds to step 144 described later. The lottery data is set in the probability lottery data storage area of the RAM 33 (step 141). That is,
Probability lottery data a2 to g2 when the number of inserted medals is two shown in the middle part of the winning probability table of FIG. 8 are set. Next, it is determined whether or not the number of inserted medals is two (step 142). If the number is two, the process proceeds to step 144 described below. If the number is not two, the probability lottery data for three medals is set in the probability lottery data storage area of the RAM 33 (step 143).
That is, shown at the bottom of the winning probability table of FIG.
Probability lottery data a3 to g when the number of inserted medals is three
3 is set.

Next, each size of the set probability lottery data is added to the probability lottery value accumulation area secured in the RAM 33 (FIG. 14, step 144). This addition is first performed with the size of the probability lottery data as aw, and the process returns from step 148 to be described later and returns to step 1
Each time 44 is performed, the size of the probability lottery data bw, c
w, dw, ew, fw, and gw are sequentially added to the probability lottery value accumulation area. Here, the sizes aw, bw, cw, dw, ew, fw, and gw of the probability lottery data are the sizes of each section of the winning mode in the winning probability table.
aw = a, bw = ba, cw = cb, dw = d-
c, ew = ed, fw = fe, gw = gf. By the first addition performed with the size of the probability lottery data as aw, the probability lottery value accumulated value D becomes aw.

Next, the random number specified by the sampling circuit 37 is set to X in the expression XD (step 145). By calculating this formula, it is determined whether or not a winning mode defined by the probability lottery data has been won (step 146). That is, X-D
It is determined whether the calculation result is positive or negative. If the calculation result is negative, that is, if the value of the random number value X is smaller than the value of the cumulative value D, the specified random number is used as the probability lottery data. It belongs to the prize mode divided by. The cumulative value D at the beginning of the process is aw, and in this case, if the calculation result is negative, the lottery result is a winning mode divided by a, that is, a small win of the lower half sun, and the process is described later. Proceed to 150.

On the other hand, if the calculation result is positive, 1 is added to the winning number stored in the winning number storage area (step 147). Initially, 1 is set in this winning number storage area in step 132, so that the winning number becomes 2 by this initial addition processing in step 147. It is understood from the table of FIG. 15 that the winning number 2 corresponds to the upper half sun. Thereafter, every time this process is performed, the winning numbers are counted up to 3, 4, 5,.... Next, it is determined whether the number of lotteries has reached the specified number stored in the lottery number storage area (step 14).
8).

If the lottery for the specified number of times has not been completed, the process returns to step 144, and bw, the size of the next probability lottery data, is added to the probability lottery value accumulation area. Then, according to the processing of steps 145 and 146, X
The calculation of −D is performed, and the sign of the calculation result is determined. When the size bw of the probability lottery data is added to the probability lottery value accumulated value D by this processing, the value of D becomes aw + bw
become. In this case, if the calculation result is negative, it is assumed that the random number specified by the sampling belongs to the prize mode divided by the probability lottery data b, the lottery result is the small win of the upper half sun, and the processing is performed. Step 1 to be described later
Go to 50.

On the other hand, if the calculation result is positive, it is determined that the winning mode defined by the probability lottery data has not been won, and the winning number is counted up according to step 147, and the winning number is set to 3. Thereafter, it is determined in step 148 whether or not the number of lotteries has reached the specified number. If not, the process returns to step 144 and the same processing as described above is repeatedly performed.

If the number of lotteries reaches the specified number in step 148, the value X of the specified random number is determined to be greater than or equal to the maximum value of the probability lottery value accumulated value D and does not belong to any of the winning modes. As a result, the lottery result is lost. Therefore, the lost number 0 is set as the winning number (step 149).

The specific processing of steps 144 to 148 is based on the case where the range of the extracted random numbers is 0 to 16384 and the data at the time of wagering three in the winning probability table shown in FIG. 8 is shown in FIG. Is performed as follows.

For example, assuming that a random number 4150 is extracted in the normal game state, X = 4150 and the initial D = 120
Since it is 0 (the size aw of the hit section data of the lower half sun), the calculation of X-D is as follows.

4150-1200 = 2950 (1) Since 2950 of this calculation result is a positive number, it is not elected, and 1 is added to the elected number set to 1 and the elected number is set to 2. . Since the specified number of lotteries in the general game state is seven, the specified number of lotteries is not completed, and the same processing is repeated again. In other words, the size bw of the next upper half sun hit section data is added to the accumulated value D, and D = 1200 + 1100 = 2300, and the next X-D calculation is performed.

4150-2300 = 1850 (2) Since 1850 of the calculation result is also a positive number, it is not elected, and 1 is added to the election number set to 2 and the election number is set to 3. . Also here, since the specified number of lotteries has not been completed, the same processing is repeated again. That is, the size cw of the next cactus hit section data is added to the accumulated value D, and D = 2300 + 1800 =
4100, and the next X-D calculation is performed.

4150-4100 = 50 (3) Since the result 50 of this calculation is still a positive number, it is not elected, and 1 is added to the election number set to 3 and the election number is set to 4. You. Also here, since the specified number of lotteries has not been completed, the same processing is repeated again. That is, the size dw of the next hat hit section data is added to the accumulated value D, and D = 4100 + 250 = 435.
The value is set to 0 and the next calculation of X-D is performed.

4150-4350 = -200 (4) Since the result of this calculation is a negative number, the winning is made, the winning number becomes 4, and the winning pattern divided by the probability lottery data d, that is, the small hit winning pattern of the hat You have been elected.

Next, whether the winning number is 7 or not, that is, CT
It is determined whether or not there is no BB prize (step 150). If there is a BB prize,
A lottery process for CT, that is, a lottery process for determining whether or not to perform a CT game is performed (step 151). In the lottery of the CT game, a random number newly generated by the random number generator 36 is extracted by the sampling circuit 37 as in the probability lottery process for determining the winning mode. Then, the sampled random value is compared with the specific value in magnitude relation. For example, if the sampled random value is smaller than the specific value, the winning is made, and the winning number is set to 8.
The fact that the result of the lottery has been won corresponds to the fact that the specific condition has been satisfied. On the other hand, when the lottery of the CT game is missed, the winning number is kept at 7.

In the present embodiment, the CT lottery process is performed as described above as a separate process from the probability lottery process for determining the winning mode. However, in the table of FIG. If the winning section is set as the winning number 8, the steps 150 and 151 become unnecessary, and the CT lottery process can be substituted for the probability lottery process routine (from step 144 to step 149) for determining the winning mode.

Next, a game state flag described later is referred to (step 152), and it is determined whether or not the game state at that time is during the CT period (step 153). If it is during the CT period, it is further determined whether or not the winning numbers are 1 to 4, that is, whether or not the small hit prize is won (step 1).
54). If it is the winning of the small hit prize, a loss number 0 is set instead of the winning numbers 1 to 4 (step 155). Therefore, in the CT period, this step 15
By the processing of 4,155, the lottery result of the small hit prize is invalidated, and the lottery is performed only for the so-called bonus prize (BB, RB prize) and the replay as shown in the table of FIG. .

Thereafter, a hit request flag corresponding to the winning number is set (step 156). The types of the hit request flags are “lower half sun”, “upper half sun”, “cactus”, “hat”, “replay”, “RB”, and “No CT B”.
There are eight types, "B" and "BB with CT", and any one of the hit request flags is set in a predetermined area of the RAM 33. If none of the hit request flags are set, "losing" occurs. As mentioned above,
“CT-less BB” is a hit request flag that is set when there is an internal hit of the BB and the player loses the lottery in a subsequent CT game. “BB with CT” is a hit request flag that is set when there is an internal hit of the BB and the lottery of the CT game is also won later.

The probability lottery process in step 108 of FIG. 11 is performed as described above. Next, reels 3 to 5
A predetermined area of the RAM 33 in which each rotational position of
Initialization is performed at the start of reel rotation (step 109 in FIG. 11). Subsequently, each of the reels 3 to 5 is driven to rotate by the stepping motor 55. Next, it is determined whether any of the stop buttons 16 to 18 has been turned on (step 110). If the ON operation has not been performed, it is determined whether or not the automatic stop timer has reached 0 (step 111). The automatic stop timer is for automatically stopping each of the reels 3 to 5 after a predetermined time elapses when the stop buttons 16 to 18 are not operated for a predetermined time.

When any one of the stop buttons 16 to 18 is turned on or the automatic stop timer becomes 0, the stop display control means 73 next sets the number of frames of the symbol drawn on the activation line, that is, the slip. The number of frames is determined (step 112). The number of sliding pieces is determined based on a game state, a winning request, the number of control pieces, a symbol position, and the like.

The game state is stored in the RAM 3 shown in FIG.
3 is stored in a 1-byte area called a game status (game status flag), and the hexadecimal data of 01 to 06 indicates the game status at that time. The gaming state stored in this gaming state status includes:
"RB working", "BB working", "General game",
There are six types of “BB inside hit”, “RB inside hit” and “CT period”.

"RB operation" indicates a game state during the RB game. RB means a regular bonus game. In this RB game, a bonus game in which a plurality of high payout games are combined can be performed once. "BB
"In operation" indicates a gaming state during the BB game. BB
Means a big bonus game and this BB
In the game, a set of the general game and the bonus game can be performed a plurality of times. "General game" is BB,
This indicates a gaming state in which no winning of RB has occurred.

"BB inside hit" is a normal game state in which the BB hit request flag is set, but a predetermined winning symbol combination is not stopped and displayed on each of the reels 3 to 5, and the BB game has not yet entered. Is represented. “RB inside hit” indicates that the RB hit request flag is set, but a predetermined winning symbol combination is not stopped and displayed on each of the reels 3 to 5 and the general gaming state in which the RB game has not yet been entered. I have.

As described above, “during the CT period” is BB,
This represents a gaming state in which the lottery of the winning combination in the RB game and the replay is performed, but the lottery of the small winning combination is invalidated.

The winning request also consists of one byte.
It is stored in the hit request flag storage area of the RAM 33 shown in FIG. For example, 1 is assigned to bit 7 of this storage area.
Is set, the hit request flag is set to "No CT B
B ”, and when 1 is set in bit 6, this means that the hit request flag is“ RB ”. Two types of hit request flags may be set at the same time. For example, the request flag per BB or R
When the B hit request flag is set, the hit request flag indicates that the symbol combination corresponding to “BB” or “RB” is not stopped and displayed on each of the reels 3 to 5 in the current game, and the next game is executed. Is also carried over. Therefore, "B
At the time of the next game of "B inside win" or "RB inside hit", if the small hit prize mode is determined by the prize mode determining means, the small hit prize hit request flag is set. Therefore, the hit request flag of “BB” or “RB” and the hit request flag of the small hit prize are simultaneously set.

As shown in FIG. 18, the number of control frames depends on the order of the symbols for which the pull-in control is prioritized.
3 is stored as a table. FIG. 7A is a pull-in priority table during a general game, and during a general game, the pull-in priority is determined in the order of replay, small hit, and BB / RB game. This priority is the priority of the winning combination that is preferentially drawn on the activated winning line. When two types of winning modes are simultaneously requested as described above, or when a winning mode is determined by the winning mode determining means, a winning mode having a higher priority is determined according to the predetermined priority. The pattern according to is preferentially drawn. The control frame number is a frame number within a range that can be controlled by the stop display control means, and during a general game, each winning combination is set to 4 frames.

FIG. 9B is a drawing-in priority table during the CT period. During the CT period, the small hit prize winning combination is controlled in the order of hat, cactus, upper half sun and lower half sun. The reel pull-in process by the stop display control unit 73 during the CT period is performed only in accordance with the pull-in priority data, because the small hit prize winning request flag is invalidated during the CT period. That is, as in the general gaming state, the pull-in control of the symbol in the winning mode according to the winning request of the small winning is not performed. The number of control frames is set to 1 for the hat and the cactus, and to 0 for the upper half sun and the lower half sun. When the number of control frames is 0, it means that the pull-in control is not performed.

The symbol position is the position data of each of the reels 3 to 5 written in the area of the RAM 33 initialized in step 109. This symbol position is the data of the symbol present at each activation line at that time, and is stored as the symbol code shown in FIG.

In determining the number of sliding frames, first, the current game state is referred to, and a priority order table corresponding to the game state is selected. In other words, if it is a general game state, FIG.
The table shown in FIG. 8A is selected, and during the CT period, the table shown in FIG. 18B is selected. Next, the number of control frames of the winning combination according to the winning request is referred to from the selected table. Thereafter, the symbol position at that time is referred to, and the symbol at that time on the activated pay line of the first stop reel is grasped. If this symbol is not a symbol corresponding to the winning request, it is determined whether there is a symbol corresponding to the winning request within the range of the number of control frames referred to. If the symbol corresponding to the winning request is within the range of the number of control frames, the number of frames from the activated winning line to the symbol is determined as the number of sliding frames.

Next, the number of sliding frames is stored in a predetermined area of the RAM 33 so that the first stop reel (rotary drum) rotates by the number of sliding frames determined in this way (FIG. 11, FIG. 11).
Step 113). However, during the CT period, the stop display control is not performed on the first stop reel and the second stop reel, so that steps 112 and 113 are not executed. Thereafter, the stop request flag of the first stop reel is set (step 114). The stop display control means 73 stops the rotation of one reel in response to the setting of the stop request flag.

Next, it is determined whether or not all the reels have stopped (step 115 in FIG. 12). If the second reel and the third reel have not been stopped, the process returns to step 110, and the above processes are repeated.

The reel stop processing of steps 110 to 115 by the stop display control means 73 is performed as follows during a general game, for example.

For example, when the ON operation of the first reel stop button 16 is detected, the first reel stop button 16
Is operated by the player, the number of drive pulses supplied to the stepping motor 55 of the first reel 3 becomes R
The information is read from the AM 33 and is associated with the rotation position of the first reel 3. When the rotational position of the first reel 3 is known, three symbols appearing in the observation window 6 are grasped as symbol codes by contrast with the symbol table (see FIG. 10).

In this case, when the big hit hit request flag is set, it is checked whether or not there is a symbol constituting the big hit on the activated pay line in the observation window 6. Similarly, when the hit request flag for medium hits and small hits is set, it is checked whether there is a symbol constituting a medium hit or small hit on the activated pay line in the observation window 6. When there is a symbol corresponding to the hit request flag on the activated pay line, the CPU 31 immediately stops the first reel 3.

As a result of the above check processing, if the symbol corresponding to the hit request flag does not appear on the activated pay line in the observation window 6, the first reel 3 is further rotated by the number of control frames (four symbols). Check what kind of symbols appear when you let them. If there is a symbol corresponding to the hit request flag, the number of sliding frames up to that frame position is reached, and the first reel 3 is rotated by the number of sliding frames and stopped there. This pull-in control process is performed in the same manner at the time of each stop control process of the second reel 4 and the third reel 5 described below.

Next, when the stop button 17 of the second reel 4 is turned on, stop control processing of the second reel 4 is performed. In this stop control process, first, in the state where the second reel 4 is rotating, first, the pay line L at the center of the observation window 7 is set.
Assuming that 21 symbols of each code number 0 to 20 stop at 1, a combination with the symbols of the first reel 3 already stopped on the activated pay line is read. In addition, a rotation code indicating that the third reel 5 is rotating is read. Although the second reel 4 is also rotating, it is assumed that the second reel 4 is stopped by the above-described processing, so that it is not read as a rotation code.

When the combination of symbol codes is read in this way, the winning symbol combination table described above is referred to and the second reel 4 rotates the 21 different rotation positions with respect to the symbol determined by stopping the first reel 3. , It is sequentially determined what kind of winning may occur on the activated winning line. For example, FIG.
Assuming that the first reel 3 has stopped as shown in FIG. 9 (a), assuming 21 stop positions of the second reel 4, the symbol combination pattern at that time is checked. For example, as shown in FIG.
At the code number "1" at the center of the symbol, the symbol combination on each of the pay lines L1, L2A, L2B, L3A, L3B is as shown in FIG.

The arrow on the third reel 5 is a rotation code indicating that the reel is being rotated. Depending on the stop position of the third reel, a big hit prize "AAA" on the prize line L2A or a prize line may be displayed. There is a possibility that a small hit prize of “CCC” may occur in L2B. Therefore, for the code number "1" on the second reel 4, a big hit prediction flag and a small hit prediction flag are set as shown in FIG. The presence or absence of such a prediction flag is checked for all code numbers on the second reel 4, and these data are written to the RAM 33.

The prediction flag data written in the RAM 33 in this manner is referred to when the second reel 4 is stopped. That is, when the stop button 17 of the second reel 4 is operated, the prediction flag corresponding to the code number of the second reel 4 is referred to. The stop control of the second reel 4 is executed such that the symbol of the big hit stops.

Next, when the ON operation of the stop button 18 of the third reel 5 is detected, the stop control processing of the third reel 5 is performed. In this stop control processing, the first reel 3 and the second reel 4 have already stopped and the combination of the symbols has been specified. Therefore, the combination of these symbols is provided for each code number of the third reel 5. The possibility of winning is determined, and a winning prediction flag is set in the same manner as in the table shown in FIG.

This prediction flag data is also referred to when the stop button 18 of the third reel 5 is operated, and when a big hit is expected, the big hit symbol is stopped on the activated pay line. Stop control of the third reel 5 is executed. At the time of the stop control processing of the third reel 5, not only a winning according to the winning request flag but also a winning different from the winning request flag can be obtained by the combination with the symbols of the first reel 3 and the second reel 4 which have already stopped. The reel stop position is controlled so as to not obtain the following.

The reel stop processing by the stop display control means during the general game is performed during the CT period.
This is not performed for the stop reel and the second stop reel. That is, similarly to the above example, the first stop reel is the first stop reel.
When the reel 3 and the second stop reel are the second reel 4, these reels 3 and 4 stop immediately at the timing when the on operation of the stop buttons 16 and 17 is detected. That is, the reels 3 and 4 are stopped only in accordance with the timing of pressing the stop buttons 16 and 17 by the player, and the stop display control means 73 does not perform the pull-in control.

During the CT period, stop display control is performed on the third stop reel. The number of control frames of the pull-in control performed at this time is 1 or 0 as shown in FIG. , The number of control frames during a general game is four. Therefore, for example, when the third stop reel is the third reel 5 as in the above example, there is no symbol corresponding to the winning combination on the activation winning line of the display window 8 at the timing when the stop button 18 is operated. In this case, it is determined whether or not there is a symbol corresponding to the winning combination in the range of one frame or zero frame from the activation line.

For example, the first reel 3 and the second reel 4
When the hats or cacti are ready, the hat or cactus is pulled down to one frame and controlled. That is, even if there is no hat or cactus on the activation line at the operation timing of the stop button 18,
If these symbols exist within the range of the number of control frames of one frame, the stop display control means 73 slides the third reel 5 by one frame, and a winning of a hat or a cactus is generated. However, since the number of control frames for the upper half sun and the lower half sun is 0, such pull-in stop display control is not performed.

When the reel stop control process is completed, a winning search process is performed (step 116 in FIG. 12). In the winning search process, the type of the winning flag indicating the combination of the symbols actually arranged on the activated winning line matches the type of the hit request flag determined by the probability lottery process. Then, it is determined whether or not the winning flag is normal (step 11).
7). If the result of this determination is not normal, for example, if the symbol combination of hats is aligned on the activated pay line and the hit request flag is a cactus flag, the medal payout number display lamp on the front panel 2 An illegal error is displayed (step 118).

If the winning flag is normal, it is next determined whether or not the winning number is 0 (step 119). If the winning number is not 0, then the game medals are stored or paid out according to the state at that time (step 1).
20). That is, in the state where the game is played with credits, the number of credits is increased by the number of medals obtained by winning, and in the state where the game is played by inserting medals into the slot 9, the number of medals obtained by winning is obtained. The number of medals is paid out to the tray 20.

Next, it is determined whether or not the winning mode is a replay winning (step 121). If the winning mode is a replay winning, an automatic insertion request is set (step 122). Then, initialization at the end of one game, for example, the area of the RAM 33 used in the game is initialized (step 123).
One game is over.

In this embodiment, the stop position of the reel symbol during the CT period depends almost on the skill of the player's operation of the stop button, as described above. One new symbol "sun" composed of "half sun" and "lower half sun" is conspicuous by occupying a large symbol area in the reel band 54, and thus is easily recognized by a player during reel rotation. Further, since the diameter of the symbol “sun” is close to the reel width of the reel band 54, the player can watch the end of the rotating reel band 54 in the width direction to change the movement of the symbol “sun” to another symbol. It becomes easy to identify from.

Therefore, even a beginner of a game having no skill can easily perform a pushing operation by using the movement of the display of this new symbol “sun” as a clue, and can easily perform the symbol “upper half”. The "sun" and "lower half sun" can be easily stopped and displayed on the winning line. As a result, a CT machine that can exhibit a skillful skill to the fullest during the CT period and is welcomed by a skilled person becomes a gaming machine that is also welcomed by a beginner.

The symbols "upper half sun" and "lower half sun" are stopped and displayed in various combinations on each activated prize line of the first reel 3 at the time of the three-stake betting game. Various modes are awarded to the player by generating modes.

That is, as shown in FIG. 21A, the symbols “upper half sun” and “lower half sun” are displayed by stopping the symbol “lower half sun” at the intersection of the winning lines L2A and L3A. And the payout number is 7 (see FIG. 6), so that 1 is obtained by the calculation formula 7 × 2 = 14.
Four payouts are given to the player. Further, as shown in FIG. 2B, the symbols “upper half sun” and “lower half sun”
The symbol "upper half sun" is stopped and displayed at the intersection of the winning lines L2A and L3A, and the symbol "lower half sun" is stopped and displayed at the winning line L1 to generate a prize in the second mode. Since there are one and seven (see FIG. 6), nine payouts are awarded to the player according to the formula 1 × 2 + 7 = 9.

As shown in FIG. 13C, the symbols “upper half sun” and “lower half sun” are displayed with the symbol “upper half sun” stopped on the pay line L1 and the symbol “lower half sun”. The sun is stopped and displayed at the intersection of the winning lines L2B and L3B, and a prize is generated in the third mode. Since each payout number is one and seven, fifteen payouts are obtained by the calculation formula 1 + 7 × 2 = 15. To the player. Also, as shown in FIG. 3D, the symbols “upper half sun” and “lower half sun”
Means that the symbol "upper sun" is the winning line L2B, L3B
And a winning is generated in the fourth mode, and the number of payouts is one. Therefore, two payouts are given to the player according to the formula 1 × 2 = 2.

Accordingly, the player can obtain four kinds of payouts by four kinds of combinations of the small win prize modes of “upper half sun” and “lower half sun”, and enter the gaming state during the CT period. Accordingly, the number of obtained medals can be finely adjusted.
