<<< Explanation of terms >>>

<Scroll (spin)>
Scrolling refers to a display in which the video reels 410a to 410e (see FIG. 1) are moved in the symbol display area 400. By scrolling the video reel 410, the symbols assigned to the video reel 410 are also displayed so as to move in the symbol display area 400. In general, the scroll moves from the top to the bottom in principle, but it may move from the bottom to the top depending on the type and direction of the game. Note that spin is synonymous with scrolling.

<Rescroll (Respin)>
The re-scrolling is a process of temporarily stopping the scrolled video reels 410a to 410e in the symbol display area 400 and then scrolling again in one unit game. It is not necessary to re-scroll all the video reels 410a to 410e, and any of the video reels 410 can be selectively re-scrolled according to the result of the symbol lottery process or the like. Respin is synonymous with rescroll.

<Stop display>
The stop display means a process of displaying a symbol in a stopped state at each of the stop positions of the symbol display area 400 when the video reels 410a to 410e are stopped.

<Relocation>
The rearrangement means stopping the video reels 410a to 410e and stopping and displaying the symbol in the symbol display area 400. By scrolling the video reels 410a to 410e, the arrangement of the symbols is once released, and then the symbols are arranged again.

<Unit game>
In both the normal game and the free game, which will be described later, the period from the time when the BET process is executed until the video reels 410a to 410e are stopped and the payout process is completed is referred to as a unit game. The BET process is an internal process and is different from the BET operation by the player. In particular, in the case of a free game, the unit game may be from the time when scrolling of the video reels 410a to 410e is started until the video reels 410a to 410e are stopped and the payout process is completed.

<Winning combination>
The winning combination means a sequence of symbols stopped and displayed along the payline 420 of the symbol display area 400, which is a target of profit. In the case of the scatter symbols described later, the number of the scatter symbols displayed as stopped is a predetermined number, and the winning combination is the one to which the profit is given. Here, the profit grant is not limited to the provision (payment) of dividends, as long as it is advantageous to the player, such as when shifting to an advantageous game.

<Scatter symbol>
The scatter symbol is a symbol whose establishment of the winning combination is judged by the number of stopped and displayed symbols. Scatter symbols are determined by the number of stopped displays, whether or not they are lined up along a valid payline 420.

<Wild symbol>
The wild symbol is a symbol that can be substituted for another symbol that is stopped and displayed in the symbol display area 400. When determining the establishment of the winning combination, the establishment of the winning combination is determined by substituting with other symbols. Wild symbols are replaced with other symbols so that a favorable winning combination is established.

If the wild symbol is stopped and displayed at the stop position where the stop position of the symbol overlaps with a plurality of valid paylines 420, the wild symbol is replaced for each payline 420 and the establishment of the winning combination is determined.

<Transition continuity>
The transition continuity means a transition from a normal game to a free game (outward route), which will be described later, and a return from the free game to the normal game (return route, and a transition from the normal game to the free game again.

<Skill game>
The skill game is a game in which the operation skill of the player is reflected in the result of the game. In particular, in the skill game of the present embodiment, the player determines the timing of the stop operation and performs the stop operation (target symbol stop operation) aiming at the stop display of the symbol targeted by the player. The player's operation skill is reflected in the judgment of the timing of the stop operation.

The present embodiment will be described below with reference to the drawings.

<<< Game types and transitions >>>
FIG. 5 is a diagram showing a transition of a game executed by the gaming machine 10.

<< Normal games and free games >>
The gaming machine 10 has a normal game and a free game. When a winning combination with a normal payout is established in a normal game or a free game, the normal payout corresponding to the winning combination is paid out.

When the winning combination of bonus symbol B1 is established in the symbol lottery process in the normal game, the game shifts to the free game according to the number of bonus symbols B1. In a free game, it becomes easier to establish a winning combination with a normal payout, and it becomes easier to obtain a higher normal payout than in a normal game. In this way, the free game is an advantageous game because the winning combination is more likely to be established than the normal game.

<Base game, high-probability game 1, high-probability game 2, high-probability game 3>
The normal game has five types of games: a base game, a high-probability game 1, a high-probability game 2, a high-probability game 3, and a high-probability game 4. The high-probability game 1, the high-probability game 2, the high-probability game 3, and the high-probability game 4 have different symbol tables. When the game shifts to the high-probability game 1, the high-probability game 2, the high-probability game 3, or the high-probability game 4, the corresponding symbol table is selected. The high-probability game 1, the high-probability game 2, the high-probability game 3, and the high-probability game 4 have a higher probability of shifting to the free game than the base game, and are easy to shift to the free game. Therefore, the high-probability game 1, the high-probability game 2, the high-probability game 3, and the high-probability game 4 are more advantageous games than the base game.

When the winning combination of the CHANGE symbol T1 and the RESPIN symbol T2 is established in the symbol lottery process in the base game, the high probability game 1, the high probability game 2, and the high probability game 2 are established according to the number of the CHANGE symbol T1 and the RESPIN symbol T2. It shifts to the probability game 3 and the high probability game 4. The end condition of the high-probability game 1, the high-probability game 2, the high-probability game 3, and the high-probability game 4 is that the unit game is played up to a predetermined number of times, for example, five times, and when the unit game is completed, the game returns to the base game.

<Rescroll (Respin)>
Further, in the base game, the high-probability game 1, the high-probability game 2, the high-probability game 3, and the high-probability game 4, the number of bonus symbols B1 determined by the symbol lottery process, and the number of CHANGE symbols T1 and RESPIN symbols T2. In response to this, re-scrolling (respinning) of the video reel 410 occurs in the same unit game. The video reel 410 in which the bonus symbol B1 is stopped and displayed is not re-scrolled, and only the video reel 410 in which the bonus symbol B1 is not stopped and displayed is re-scrolled. At the time of rescrolling, the symbol lottery process is executed again, and when the bonus symbol B1 is stopped and displayed, the number of bonus symbols B1 stopped and displayed in the symbol display area 400 can be additionally increased. In this way, the possibility that the winning combination of the bonus symbol B1 is established can be increased, and the transition to the free game can be facilitated.

<Types of respin (respin A, respin B, respin C)>
The gaming machine 10 has three types of respins, respin A, respin B, and respin C. Respin A, Respin B, and Respin C have different symbol tables from each other. Respin A, respin B, and respin C are selected when conditions such as stop display of the bonus symbol B1 are satisfied, and the corresponding symbol table is selected.

Respin A is a normal respin, and when respin A is selected, it can be respinned up to 3 times in the unit game. When Respin B is selected, after the four bonus symbols B1 are stopped and displayed, the unit game is re-spinned only once. When respin C is selected, after 3 or 4 bonus symbols B1 are stopped and displayed in the high-probability game 4, the unit game is re-spinned only once, and as a result, 5 bonus symbols B1 are stopped. It is displayed and the winning combination of the bonus symbol B1 is always established.

When deciding to execute re-spin, determine the number of re-spins. When the re-spin is performed three times, the symbol table is switched to the symbol table in which the winning combination of three or more bonus symbols B1 is established by at least the third re-spin. After the winning combination of 3 or 4 bonus symbols B1 is established in the high probability game 4, the symbol table is switched to the symbol table in which the winning combination of 5 bonus symbols B1 is established. Other than the high-probability game 4, after the winning combination of the four bonus symbols B1 is established, it is switched to the symbol table that fuels the expectation that the winning combination of the five bonus symbols B1 is established. Other than the high-probability game 4, when the winning combination of the three bonus symbols B1 is established, the re-spin ends.

<Free game A, free game B, free game C>
The free game has three types of games, a free game A, a free game B, and a free game C. In a free game, a winning combination with a normal payout is likely to be established, and a higher normal payout can be obtained than in a normal game.

The contents of the free game A and the free game B are the same. Free game A and free game B have different return destinations in the normal game. The return destination will be described later. Free game A and free game B have three types of bonus games, a lion bonus game, a gorilla bonus game, and a ostrich bonus game. The lion bonus game, gorilla bonus game, and ostrich bonus game can be selected by the player's operation.

Free game C has an elephant bonus game. The elephant bonus game cannot be selected by the player's operation.

The end condition of the lion bonus game, gorilla bonus game, ostrich bonus game, and elephant bonus game is to play the unit game up to a predetermined number of times, for example, 5 times, and when it ends, high probability game 2, high probability game 3, high Return to any of the probability games 4.

<Transition continuity 1>
When the winning combination of 3 or 4 bonus symbols B1 is established in the base game, the high probability game 1 or the high probability game 2, the base game or the high probability game 1 shifts to the free game A. When the unit game is played up to a predetermined number of times in the free game A, the free game A ends and the game shifts to the high probability game 3. When the winning combination of 3 or 4 bonus symbols B1 is established again in the high-probability game 3, the high-probability game 3 shifts to the free game B. When the unit game is played up to a predetermined number of times in the free game B, the free game B ends and the game shifts to the high probability game 2. In the high-probability game 2, when the winning combination of 3 or 4 bonus symbols B1 is established, the game can be shifted to the free game A.

<Transition continuity 2>
When the winning combination of the five bonus symbols B1 is established in the base game or the high-probability game 4, the game shifts from the base game or the high-probability game 4 to the free game C. When the unit game is played up to a predetermined number of times in the free game C, the free game C is terminated and the game shifts to the high probability game 4 again. In the high-probability game 4, when the winning combination of the five bonus symbols B1 is established again, the game can be shifted to the free game C.

<Multi-feature game>
The free game A, the free game B, and the free game C have a multi-feature game. The multi-feature game is executed when the lottery process is won. When a multi-feature game is won, a special multiplying factor or an addition multiplying factor to be multiplied by a normal payout, a JACKPOT payout, etc. are determined by lottery processing. Furthermore, the number of payouts can be increased. The special rate, addition rate, and JACKPOT dividend will be described later.

<Skill game>
The free game A, the free game B, and the free game C have a skill game. The skill game can be selected by the operation of the player. The skill game is executed when the specific symbols are arranged in a predetermined line along the payline. The specific symbol will be described later.

In the skill game, the video reel 410 in which the bonus symbol B1 is stopped and displayed does not scroll, and the video reel 410 in which the symbol B1 is not stopped and displayed scrolls again. At the time of rescrolling, if the symbol lottery process is executed again and the specific symbol can be stopped and displayed along the payline, the number of the specific symbol to be stopped and displayed in the symbol display area 400 is additionally increased. Can be done. In this way, the possibility of establishing a winning combination of specific symbols is increased.

<Specific symbol>
A specific symbol is a symbol associated with a bonus game type. Specifically, the specific symbols are associated as follows. W1, G1, and S1 are associated with the lion bonus game (without skill game). W1, G2, and S2 are associated with the gorilla bonus game (without skill game). W1, G3, and S3 are associated with the ostrich bonus game (without skill game). W1, G4, and S4 are associated with the elephant bonus game (without skill game). W1, G1, and S1 are associated with the lion bonus game (with skill game). W1, G2, and S2 are associated with the gorilla bonus game (with skill game). W1, G3, and S3 are associated with the ostrich bonus game (with skill game). W1, G4, and S4 are associated with the elephant bonus game (with skill game).

In the following, the processing of the gaming machine 10 will be described with reference to FIGS. 6, 7, 9, 9, 12, 16 to 20, FIG. 22, and FIGS. 27 to 28. It is assumed that the gaming machine 10 has completed startup processing such as initialization and is operating steadily. Further, it is assumed that the reading device 250, the bill insertion device 260, and the like are operated by the player to insert the necessary credits.

<<< Normal game processing >>>
FIG. 6 is a flowchart showing a normal game process called and executed in the normal game.

First, when the power is turned on to the gaming machine 10, the CPU 110 of the controller 100 reads the BIOS from the ROM 120 and executes it, then reads the game program from the storage device 140, deploys it executably in the RAM 130, and stores it ( Step S611).

Next, the CPU 110 of the controller 100 executes the initialization process at the end of the unit game (step S613). For example, the number of BETs, symbols determined by the lottery process, and the like are initialized. Also, the number of games is subtracted. When the re-spin described later is performed, the number of games is not subtracted, but the number of re-spins is subtracted.

Next, the CPU 110 of the controller 100 reads and executes the BET process / SPIN button process shown in FIG. 7 (step S615). In this process, it is determined whether or not the BET button 320 or the SPIN button 330 has been operated by the player, and the processing of the number of credits owned by the player is executed.

Next, the CPU 110 of the controller 100 selects the symbol table (step S617). In this process, the symbol table is selected according to the conditions of the symbol table selection table shown in FIG.

Next, the CPU 110 of the controller 100 calls and executes the lottery process shown in FIG. 9 (step S619). This lottery process includes a stop symbol lottery process, a respin determination process, a game transition lottery process 3, a game transition lottery process 1, and an effect lottery process. The stop symbol lottery process determines a predetermined position in the symbol display area 400, for example, a symbol to be stopped and displayed at the bottom. The details of the lottery process will be described in detail later.

Next, the CPU 110 of the controller 100 calls and executes the scroll display control process shown in FIG. 16 (step S621). By this process, the five video reels 410a to 410e are scrolled and then stopped in the symbol display area 400 of the lower display 210. In this way, a total of 20 symbols are rearranged in a 4-by-5 matrix. The details of the scroll display control process will be described in detail later.

Next, the CPU 110 of the controller 100 calls and executes the payout number determination process shown in FIG. 17 (step S623). It is determined whether or not the winning combination has been established, and the total payout to be paid out is determined by calculating the sum of the payouts for which the winning combination has been established. The details of the payout number determination process will be described in detail later.

Next, the CPU 110 of the controller 100 permits the settlement process (step S624). The player can print out the possessed credits on the ticket payout device 270 and end the play on the gaming machine 10.

Next, the CPU 110 of the controller 100 determines whether or not the free game transition condition is satisfied (step S625). The free game transition condition is that the winning combination of the bonus symbol B1 is established. Specifically, when 3 to 5 bonus symbols B1 are stopped and displayed in the symbol display area 400, the free game transition condition is satisfied.

When the CPU 110 of the controller 100 determines in the determination process of step S625 that the free game transition condition is not satisfied (NO), it determines whether or not there is a transition in the normal game (step S627). The transition to any one of the base game and the high-probability game 1 to the high-probability game 4 is determined by the game transition lottery process 1 and the game transition lottery process 3 described later.

Next, when the CPU 110 of the controller 100 determines in the determination process of step S627 that there is no transition in the normal game (NO), the process immediately returns to step S613. As a result, a new unit game is started while maintaining the same game as the normal game.

On the other hand, when the CPU 110 of the controller 100 determines in the determination process of step S627 that there is a transition in the normal game (YES), the CPU 110 of the controller 100 executes the game transition process shown in FIG. 27 (step S628), and the game of the migration destination The number of games in the above is set (step S629), the game is transferred to the destination game (step S631), and the process is returned to step S613. As a result, a new unit game in the destination game in the normal game is started.

When the CPU 110 of the controller 100 determines in the determination process of step S625 that the free game transition condition is satisfied (YES), the CPU 110 of the controller 100 calls and executes the free game process of FIG. 19 (step S633).

Next, the CPU 110 of the controller 100 executes the game transition lottery process 2 (step S635), executes the processes of step S629 and step S631, and returns the process to step S613. As a result, the game returns from the free game to the base game, the high-probability game 1 to the high-probability game 4, and a new unit game is started.

The game transition lottery process 2 is a process of determining whether to return to the base game of the normal game, the high-probability game 1 to the high-probability game 4 when returning from the free game to the normal game by the lottery process. is there. The lottery process is executed according to the types of the free games A, B, and C, and the winning or non-winning of the base game, the high-probability game 1 to the high-probability game 4 is determined.

FIG. 11B is a number table of the game transition lottery process 2, and shows the ease of winning or non-winning of the base game, the high-probability game 1 to the high-probability game 4. In addition, the number is a ratio comparing the numerical range corresponding to the winning, which is determined to determine the winning or non-winning (loss) by extracting the random number value, and the numerical range corresponding to the non-winning. Is. If the extracted random number value is included in the numerical range corresponding to winning, the lottery result is won, and if it is included in the numerical range corresponding to non-winning, the lottery result is non-winning. In the example shown in FIG. 11B, the free game A is uniquely returned to the high probability game 3, the free game B is uniquely returned to the high probability game 2, and the free game C is uniquely returned to the high probability game 4. The number of games is fixed. The number of values shown in the game transition number table 2 can be appropriately determined, and can be variously returned to any one of a free game, a base game, and a high-probability game 1 to a high-probability game 4. ..

<<< Symbol table selection table in normal game >>>
FIG. 8 is a symbol table selection table for selecting a symbol table in a normal game. The symbol table selection table is used in the process of step S617 of the normal game process of FIG.

First, the CPU 110 of the controller 100 selects the symbol table for the base game when it is a base game when none of the respins A to C is selected, and when it is the high probability game 1, the high probability game The symbol table for 1 is selected, the symbol table for the high probability game 2 is selected when the high probability game 2 is used, and the symbol table for the high probability game 3 is selected when the high probability game 3 is used.

The random number value is extracted from the range corresponding to the number of symbols specified in the symbol table.

Next, the CPU 110 of the controller 100 refers to the symbol table selected in the symbol table selection process of step S617 of FIG. 6 and determines a stop symbol for each of the video reels 410a to 410e from the random value (step S1013). The scrolling of the video reels 410a to 410e is stopped so that the symbol determined by this process is stopped and displayed at a predetermined position in the symbol display area 400, for example, at the bottom. By determining the symbol to be stopped and displayed at the bottom, it is possible to determine the symbol (symbol to be rearranged) to be stopped and displayed at each of the stop positions of 4 rows and 5 columns in the symbol display area 400.

Next, the CPU 110 of the controller 100 ends this subroutine when the symbol determined in the process of step S1013 is stored in the RAM 130 of the controller 100 (step S1015). By storing the symbol determined in the process of step S1013 in the RAM 130, it can be used for controlling the stop display of the symbol and calculating the payout.

At the time of re-spinning, only the video reel 410 to be re-spun out of the video reels 410a to 410e is subjected to the symbol lottery process with reference to the re-spin symbol table.

<<< Respin determination process >>
FIG. 12 is a flowchart showing the respin determination process. This process is called and executed in step S913 of the lottery process of FIG.

First, the CPU 110 of the controller 100 determines whether or not the current number of respins is greater than 0 (step S1211). That is, it is determined whether or not respin remains.

When the CPU 110 of the controller 100 determines in the determination process of step S1211 that the current number of respins is greater than 0 (YES), it immediately terminates this subroutine.

When the CPU 110 of the controller 100 determines in the determination process of step S1211 that the current number of respins is not greater than 0 (NO), that is, when the respin is not determined, the number of B1 (BONUS) displayed as a stop is displayed. Is 0, 1 or 2 (step S1213).

When the CPU 110 of the controller 100 determines in the determination process of step S1213 that the number of B1 (BONUS) stopped and displayed is 0, 1 or 2 (YES), the respin lottery process 1 is executed (step S1215). , The type of respin is determined to be respin A (step S1217), and this subroutine is terminated.

The respin lottery process 1 is executed in each of the base game of the normal game, the high probability game 1, the high probability game 2, the high probability game 3, and the high probability game 4. Further, the respin lottery process 1 refers to the respin lottery table 1 according to the sum of the number of B1 (BONUS) stopped and displayed, the number of T1 (CHANGE) and the number of T2 (RESPIN), and a random number value. The maximum number of respins is determined from.

<Transition from free game A to high-probability game 3>
When the unit game is played up to a predetermined number of times in the free game A, the end condition of the free game A is satisfied, and the game shifts from the free game A to the high probability game 3 (see FIG. 5). The transition from the free game A to the high-probability game 3 is uniquely determined (see the number table in the game transition lottery table 2 in FIG. 11B).

<Transition from high-probability game 3 to free game B>
In the high-probability game 3, first, the symbol table for the high-probability game 3 is selected (see steps S617 and 8 in FIG. 6). As described above, in the high-probability game 3, the maximum number of re-spins tends to be larger than in the high-probability game 2 (see FIG. 14). Further, the symbol table of Respin A (Respin A) is selected (see steps S1217 and 8 of FIG. 12). Since the symbol table Respin A is used, it becomes easy to win the bonus symbol B1.

Respin is performed up to the maximum number of respins, and each time the respin is performed, the symbol tables of RespinB, RespinC1, RespinC2, and RespinC3 are selected according to the number of bonus symbols B1 stopped and displayed in the symbol display area 400. , It becomes easier to win the bonus symbol B1. When three or four bonus symbols B1 are stopped and displayed in the symbol display area 400, the transition condition to the free game B is satisfied. When the transition condition to the free game B is satisfied, the high probability game 3 is shifted to the free game B. The transition from the high-probability game 3 to the free game B is uniquely determined.

In this way, when the first free game is the free game A, after the free game A is finished, the game can be shifted to the free game B via the high probability game 3, and the two free games continue. It will be easier. In this way, the first continuation of the transition is realized.

<Transition from free game B to high-probability game 2>
When the unit game is played up to a predetermined number of times in the free game B, the transition condition is satisfied and the game shifts from the free game B to the high probability game 2. The transition from the free game B to the high-probability game 2 is uniquely determined (see the number table in the game transition lottery table 2 in FIG. 11B).

<Transition from high-probability game 2 to free game A>
In the high-probability game 2, the symbol table for the high-probability game 2 is selected (see steps S617 and 8 in FIG. 6). As described above, in the high-probability game 2, the maximum number of re-spins tends to be smaller than that in the high-probability game 3 (see FIG. 14), and re-spins are less likely to occur. Even in the high-probability game 2, since the symbol table (Respin A) of Respin A is selected (see steps S1217 and 8 in FIG. 12), it becomes easy to win the bonus symbol B1.

However, as described above, since respin is unlikely to occur, the number of games reaches a predetermined number of times before the three or four bonus symbols B1 are stopped and displayed in the symbol display area 400, and the high probability game 2 starts. It will be easier to move to the base game. In this way, it becomes difficult to shift from the high-probability game 2 to the free game A.

As described above, when the first free game is the free game A, after the free game A is finished, the game shifts to the free game B via the high probability game 3, and the free game B is finished. After that, it becomes difficult to shift to the free game A, and it becomes difficult to continue the three free games.

Even in the high-probability game 2, if the bonus symbol B1 is won and three or four bonus symbols B1 are stopped and displayed in the symbol display area 400, the transition condition is satisfied and the game shifts to the free game A. To do. The transition from the high-probability game 2 to the free game A is uniquely determined. When the first free game is free game A, after the free game A is finished, the game shifts to the free game B via the high probability game 3, and after the free game B is finished, the game is changed to the free game A. If the game can be transferred, as described above, it becomes easier to transfer to the free game B again, and the four free games will continue.

In this way, the free games of 2 times, 4 times, ... are easy to continue, and the free games of 3 times, 5 times, ... are difficult to continue.

<Continuing the second transition (transition to free game C)>
When shifting to the high-probability game 4, first, the symbol table for the high-probability game 4 is selected (see steps S617 and 8 in FIG. 6). As described above, in the high-probability game 4, as in the high-probability game 3, the maximum number of respins tends to be larger than in the high-probability game 2 (see FIG. 14). Further, also in the high probability game 4, the symbol table (Respin A) of Respin A is selected (see steps S1217 and 8 in FIG. 12). Since the symbol table Respin A is used, it becomes easy to win the bonus symbol B1.

Respin is performed up to the maximum number of respins, and each time the respin is performed, the symbol tables of RespinB, RespinC1, RespinC2, and RespinC3 are selected according to the number of bonus symbols B1 stopped and displayed in the symbol display area 400. , It becomes easier to win the bonus symbol B1. When three or four bonus symbols B1 are stopped and displayed in the symbol display area 400, the symbol table of respin C (RespinE1 and RespinE2) is selected, and it becomes easier to win the bonus symbol B1. The transition condition is satisfied when the five bonus symbols B1 are stopped and displayed in the symbol display area 400. When the transition condition is satisfied, the high-probability game 4 is shifted to the free game C. The transition from the high-probability game 4 to the free game C is uniquely determined.

<Transition from free game C to high-probability game 4>
When the unit game is played up to a predetermined number of times in the free game C, the transition condition is satisfied and the game shifts from the free game C to the high probability game 4. The transition from the free game C to the high-probability game 4 is uniquely determined (see the number table in the game transition lottery table 2 in FIG. 11B).

As mentioned above, the high-probability game 4 is easy to shift to the free game C. Therefore, a second round trip between the high-probability game 4 and the free game C due to the transition of the outbound route from the high-probability game 4 to the free game C and the transition of the return route from the free game C to the high-probability game 4. The transition will be continued. That is, two types of transition continuation different from each other are realized: the first transition continuation and the second transition continuation separate from the first transition continuation.

<<< Free game processing >>>
FIG. 19 is a flowchart showing free game processing. This process is called and executed in step S633 of the normal game process of FIG. In the free game, the BET multiplier of the unit game immediately before the transition to the free game is maintained and used. Specifically, the BET magnification (step S717 in FIG. 7) stored in the RAM 130 in the unit game of the normal game immediately before the transition to the free game is read and used.

First, the CPU 110 of the controller 100 executes the free game start process shown in FIG. 20A (step S1911). The free game start process executes determination of the type of free game, selection of the type of bonus game, selection of presence / absence of skill game, and the like. The details of the free game start process will be described later.

Next, the CPU 110 of the controller 100 executes the unit game initialization process (step S1913). For example, a symbol determined by the lottery process is initialized. As described above, the BET multiplier is maintained at the value in the normal game and is not initialized in the free game.

Next, the CPU 110 of the controller 100 determines whether or not to execute the skill game in this unit game (step S1915). The skill game runs when selected by the player.

When the CPU 110 of the controller 100 determines in the determination process of step S1915 that the skill game is not executed (NO), 1 is subtracted from the number of free games (step S1917).

Next, when the CPU 110 of the controller 100 determines in the determination process of step S1915 that the skill game is to be executed (YES), or when the process of step S1917 is executed, the type of bonus game, the presence or absence of the skill game, and so on. The symbol table is selected according to whether or not to execute the skill game (step S1919).

As mentioned above, the bonus games are Lion Bonus Game (No Skill Game), Gorilla Bonus Game (No Skill Game), Butterfly Bonus Game (No Skill Game), Elephant Bonus Game (No Skill Game), Lion Bonus Game (Skill) It has eight types of games: gorilla bonus game (with skill game), ostrich bonus game (with skill game), and elephant bonus game (with skill game).

In addition, the four types of games, Lion Bonus Game (with skill game), Gorilla Bonus Game (with skill game), Butterfly Bonus Game (with skill game), and Elephant Bonus Game (with skill game), are each before the start of the skill game. Has a game and a skill game.

Therefore, in the present embodiment, the symbol table used in the free game is a lion bonus game (without skill game), a gorilla bonus game (without skill game), a ostrich bonus game (without skill game), and an elephant bonus game (skill game). (None), Lion bonus game (with skill game) skill game before start, Lion bonus game (with skill game) skill game, Gorilla bonus game (with skill game) skill game before start game, Gorilla bonus game (skill) Skill game of (with game), skill game of ostrich bonus game (with skill game), skill game of ostrich bonus game (with skill game), skill game of elephant bonus game (with skill game), elephant It is defined for each of the 12 types of skill games of bonus games (with skill games). The process of step S1919 is a process of selecting a symbol table corresponding to these 12 types of games according to the type of bonus game, the presence / absence of a skill game, and whether or not to execute the skill game.

Next, the CPU 110 of the controller 100 executes the stop symbol lottery process using the symbol table selected in step S1919 (step S1921).

Next, the CPU 110 of the controller 100 determines whether or not the skill game is selected in the process of step S2017 in FIG. 20A (step S1925).

When the CPU 110 of the controller 100 determines that the skill game has not been selected in the determination process of step S1925 (NO), the CPU 110 of the controller 100 executes the multi-feature process shown in FIG. 22 (step S1927). The multi-feature process is a process of executing a multi-feature distribution lottery process when a multi-feature is won and determining a special payout ratio and a JACKPOT payout. Details of multi-feature processing will be described later.

When the CPU 110 of the controller 100 determines that the skill game is selected in the determination process of step S1925 (YES), the skill chance lottery process shown in FIG. 20B is executed (step S1923).

When the CPU 110 of the controller 100 executes the process of step S1923 or the process of step S1927, it executes the scroll display control process of FIG. 16 (step S1929).

Next, the CPU 110 of the controller 100 executes the payout number determination process shown in FIG. 17 (step S1931).

Next, the CPU 110 of the controller 100 determines whether or not the number of free games is 0 (step S1933).

When the CPU 110 of the controller 100 determines that the number of free games is not 0 (NO), the process returns to step S1913.

When the CPU 110 of the controller 100 determines that the number of free games is 0 (YES), the settlement process is permitted (step S1935), and this subroutine is terminated. By doing so, after the free game is finished, the owned credit can be printed by the ticket payout device 270 and the play on the gaming machine 10 can be finished.

After finishing this subroutine, return to any of the high-probability games 1 to 4. The CPU 110 of the controller 100 returns to the high-probability game 3 when the free game A ends, returns to the high-probability game 2 when the free game B ends, and returns to the high-probability game 4 when the free game C ends.

<<< Free game start processing >>>
FIG. 20A is a flowchart showing a free game start process. This process is called in step S1911 of the free game process of FIG.

First, the CPU 110 of the controller 100 prohibits the settlement process (step S2010).

Next, the CPU 110 of the controller 100 determines whether or not the five bonus symbols B1 are stopped and displayed in the unit game of the normal game immediately before the transition to the free game (step S2011).

When the CPU 110 of the controller 100 determines in the determination process of step S2011 that the five bonus symbols B1 are not stopped and displayed (NO), the free game depends on the type of the normal game immediately before the transition to the free game. A or free game B is determined (step S2013).

Specifically, the CPU 110 of the controller 100 selects the free game A when the normal game immediately before shifting to the free game is the base game. The CPU 110 of the controller 100 selects the free game A when the normal game immediately before shifting to the free game is the high probability game 1. The CPU 110 of the controller 100 selects the free game A when the normal game immediately before shifting to the free game is the high probability game 2. The CPU 110 of the controller 100 selects the free game B when the normal game immediately before shifting to the free game is the high probability game 3.

Next, the CPU 110 of the controller 100 displays a bonus game selection screen on the lower display 210, and the player operates the touch panel 340 to determine the selected bonus game type (step S2015). The bonus games that the player can select in the process of step S2015 are three types of bonus games, excluding the elephant bonus game, the lion bonus game, the gorilla bonus game, and the ostrich bonus game. Players can choose one of these types of bonus games.

When the CPU 110 of the controller 100 determines in the determination process of step S2011 that the five bonus symbols B1 are stopped and displayed (NO), the CPU 110 determines the free game C (step S2021). Free game C has an elephant bonus game. Therefore, when the five bonus symbols B1 are stopped and displayed and the game shifts to the free game, the free game C is selected and the elephant bonus game is executed without depending on the player's selection operation.

After executing the process of step S2015 or S2221, the CPU 110 of the controller 100 displays a selection screen for executing or not executing the skill game on the lower display 210, and the player operates the touch panel 340 to select the skill game. Determining execution or non-execution (step S2017). When the player chooses to run the skill game, the skill game is run. The details of the skill game will be described later.

Next, the CPU 110 of the controller 100 sets the number of games according to the type of the selected bonus game (step S2019). In the present embodiment, 5 is set in the number of games regardless of which of the lion bonus game, the gorilla bonus game, the ostrich bonus game, and the elephant bonus game is selected.

Next, the CPU 110 of the controller 100 adds 1 to the free game continuation counter (step S2021). The free game continuation counter is a counter for counting the number of times the free game continues when the free game continues.

Next, the CPU 110 of the controller 100 prohibits the printing of the owned credit on the ticket payout device 270 (step S2023), and ends this subroutine.

<< Skill chance lottery processing >>
FIG. 20B is a flowchart showing the skill chance lottery process. This process is called in step S1923 of the free game process of FIG.

First, the CPU 110 of the controller 100 determines whether or not the skill chance lottery has already been executed (step S2051).

When the CPU 110 of the controller 100 determines that the skill chance lottery has not been executed yet (NO), it executes the skill chance lottery process (step S2053), terminates this subroutine, and determines that the skill chance lottery has already been executed. When (NO), this subroutine is immediately terminated.

The skill chance lottery process is executed on the condition that the specific symbols are arranged in a predetermined line along the valid payline based on the stop symbol determined in the stop symbol lottery process in step S1921. The predetermined sequence is a sequence in which only a part of a specific winning combination among the winning combinations is established. That is, if the remaining specific symbols are stopped and displayed on the valid payline (if they are aligned), there is a possibility that a specific winning combination will be established. In other words, it is a winning combination incomplete state immediately before the final state in which a specific winning combination is established. For example, one specific winning combination is one in which the specific symbols are stopped and displayed for each of all the video reels 410a to 410e, and the specific symbols are arranged in a predetermined arrangement along a valid payline.

Specifically, among the video reels 410a to 410e, if only the video reel 410a is not aligned, if only the video reel 410b is not aligned, if only the video reel 410c is not aligned, only the video reel 410d is not aligned. In that case, only the video reel 410e may not be available.

In the skill chance lottery process, the lottery process is executed according to the type of the selected bonus game, and the winning or non-winning of the skill chance is determined. FIG. 21 is a figurative table showing the ease of winning or not winning a skill chance. As shown in FIG. 21, when only the video reel 410a is not aligned (× ○○○○) and when only the video reel 410b is not aligned (○ × ○○○), only the video reel 410c is not aligned. (○○ × ○○), when only the video reel 410d is not available (○○○ × ○), and when only the video reel 410e is not available (○○○○ ×). The number is fixed. In the example of the number table shown in FIG. 21, the case where the skill chance is always won is shown, but the number of the number table can be appropriately determined, and the skill chance may not be won.

<<< Multi-feature processing >>>
FIG. 22 is a flowchart showing the multi-feature processing. This process is called in step S1927 of the free game process of FIG.

First, the CPU 110 of the controller 100 determines whether or not the winning combination of the specific symbols has been established (step S2211).

When the CPU 110 of the controller 100 determines in the determination process of step S2211 that the winning combination of the specific symbol is not established (NO), the subroutine is immediately terminated.

When the CPU 110 of the controller 100 determines in the determination process of step S2211 that the winning combination of the specific symbols has been established (YES), the CPU 110 executes the multi-feature lottery process (step S2213).

FIG. 23 is a number table for the multi-feature lottery process, and shows the ease of winning or not winning the multi-feature. FIG. 23 shows a table of numbers when a skill game is not selected in the lion bonus game. For each of the lion bonus game, gorilla bonus game, ostrich bonus game, and elephant bonus game, all number tables are defined when the skill game is not selected and when it is selected (not shown).

As shown in FIG. 23, the number of winning or non-winning multi-features is determined according to the number of special color specific symbols and the number of specific symbols included in the established winning combination.

As shown in FIG. 23, when the skill game is not selected in the lion bonus game, regardless of the number of special color specific symbols, when the number of specific symbols is 2, it is always non-winning and the specific symbol When the number is 3 to 5, you will always win. Also, even if the skill game is selected in the lion bonus game, regardless of the number of special color specific symbols, if the number of specific symbols is 2, it will always be non-winning, and the number of specific symbols will be 3 or more. When there are five, you will always win (not shown).

Furthermore, in this embodiment, it is defined as follows. If the skill game is not selected or is selected in the gorilla bonus game, regardless of the number of special color specific symbols, the player will always win when the number of specific symbols is 2 to 5. When the skill game is not selected or selected in the ostrich bonus game, regardless of the number of special color specific symbols, when the number of specific symbols is 2 to 4, it is always non-winning and specific You will always win when the number of symbols is five.

If the skill game is not selected in the elephant bonus game, you will always win when the number of specific symbols is 2 to 5, regardless of the number of special color specific symbols. When the skill game is selected in the elephant bonus game, regardless of the number of special color specific symbols, when the number of specific symbols is 2 to 4, it is always non-winning and the number of specific symbols is 5. You will always win at.

Next, the CPU 110 of the controller 100 determines whether or not the multi-feature has been won by the process of step S2213 (step S2215).

Next, when the CPU 110 of the controller 100 determines in the determination process of step S2215 that the multi-feature has been won (YES), the JACKPOT winning number of times is initialized (step S2217), and the JACKPOT payout is initialized (step S2219). ..

Next, the CPU 110 of the controller 100 selects the multi-feature distribution lottery table according to the number of times the JACKPOT is won (step S2221).

If JACKPOT has not yet been won in the multi-feature distribution lottery in step S2223, or if the JACKPOT has been won only once, a multi-feature distribution lottery table that can win either the special payout ratio or the JACKPOT payout is selected. On the other hand, when JACKPOT is won twice in the multi-feature distribution lottery, a multi-feature distribution lottery table that can win only the special payout ratio is selected. That is, the JACKPOT can be won up to twice, and when the JACKPOT is won twice, only the special payout ratio is won.

Next, the CPU 110 of the controller 100 refers to the multi-feature distribution lottery table selected in step S2221 and executes the multi-feature distribution lottery process (step S2223).

FIGS. 24 and 25 are table numbers for the multi-feature distribution lottery process, and show the ease of winning or not winning the special payout ratio or JACKPOT payout. As shown in FIGS. 24 and 25, the number of winning or non-winning multi-features is determined according to the number of special color specific symbols and the number of specific symbols included in the established winning combination.

The number table shown in FIGS. 24 and 25 is the first multi-feature distribution lottery process, and is a number table when the lion bonus game is selected and the skill game is not selected. The number table is also set for the bonus game (with or without skill game). That is, the following 24 types (L-1-1) to (E-3-2) are defined as the number table for the multi-feature distribution lottery process.
(L-1-1) 1st lottery process, lion bonus game, no skill game (L-2-1) 2nd lottery process, lion bonus game, no skill game (L-3-1) 1st 3rd lottery process, lion bonus game, no skill game (G-1-1) 1st lottery process, gorilla bonus game, no skill game (G-2-1) 2nd lottery process, gorilla bonus No game, no skill game (G-3-1) 3rd lottery process, gorilla bonus game, no skill game (O-1-1) 1st lottery process, no ostrich bonus game, no skill game (O- 2-1) 2nd lottery process, ostrich bonus game, no skill game (O-3-1) 3rd lottery process, ostrich bonus game, no skill game (E-1-1) 1st time Lottery processing, elephant bonus game, no skill game (E-2-1) 2nd lottery processing, elephant bonus game, no skill game (E-3-1) 3rd lottery processing, elephant bonus game, skill No game (L-1-2) 1st lottery process, lion bonus game, skill game available (L-2-2) 2nd lottery process, lion bonus game, skill game available (L-3-2) ) 3rd lottery process, lion bonus game, skill game available (G-1-2) 1st lottery process, gorilla bonus game, skill game available (G-2-2) 2nd lottery process, Gorilla bonus game, skill game available (G-3-2) 3rd lottery process, gorilla bonus game, skill game available (O-1-2) 1st lottery process, ostrich bonus game, skill game available (O-1-2) O-2-2) 2nd lottery process, ostrich bonus game, skill game available (O-3-2) 3rd lottery process, ostrich bonus game, skill game available (E-1-2) 1st 2nd lottery process, elephant bonus game, skill game available (E-2-2) 2nd lottery process, elephant bonus game, skill game available (E-3-2) 3rd lottery process, elephant bonus game , There is a skill game

As described above, the number tables (L-3-1), (G-3-1), (O-3-1), and (E-3-1) at the time of the third lottery process are Neither wins the JACKPOT dividend.

The special payout ratio is determined according to the number of special color specific symbols included in the established winning combination, and the special payout ratio is (1 + number of special color specific symbols) times, (2 + number of special color specific symbols) times, (3 + number of special color specific symbols) times, (5 + number of special color specific symbols) times, (10 + number of special color specific symbols) times, (20 + number of special color specific symbols) times, (50 + number of special color specific symbols) times (Number of) times, (100 + number of special color specific symbols) times. For example, when the number of special color specific symbols included in the established winning combination is 0, the special payout ratios are 1x, 2x, 3x, 5x, 10x, 20x, 50x, and 100x, respectively. It becomes. Also, when the number of special color specific symbols included in the established winning combination is 3, (1 + 3) times, (2 + 3) times, (3 + 3) times, (5 + 3) times, (10 + 3) times, (20 + 3) times, It becomes (50 + 3) times and (100 + 3) times.

In addition, as JACKPOT dividends, the number of units is set for four types: MINI, MINIOR, and GRAND.

In the number table of (L-1-1) of the lion bonus game, regardless of the number of special color specific symbols, for all 2 to 5 specific symbols, (1 + special color specific symbols The number of times is 0, the number of times (2 + number of special color specific symbols) is 500,000, the number of times (3 + number of special color specific symbols) is 400,000, and (5 + number of special color specific symbols) The number of multiples is 61798, the number of multiples (10 + number of special color specific symbols) is 25000, and the number of multiples (20 + number of special color specific symbols) is 5000, and (50 + number of special color specific symbols).

<JACKPOT dividend>
In all of the lion bonus game, gorilla bonus game, ostrich bonus game, and elephant bonus game, the JACKPOT payout decreases as the number of lottery increases.

In the case of no skill game, the ostrich bonus game is the largest, then the lion bonus game is the largest, then the elephant bonus game is the largest, and the gorilla bonus game is the smallest.

If there is a skill game, the ostrich bonus game and the elephant bonus game are the largest, the lion bonus game is the second largest, and the gorilla bonus game is the smallest.

In the lion bonus game, the JACKPOT payout is smaller with the skill game than without the skill game, and in the elephant bonus game, the JACKPOT payout is larger with the skill game than without the skill game. In addition, other gorilla bonus games and ostrich bonus games have the same number of JACKPOT payouts as those with skill games and those without skill games.

After executing the process of step S2223 described above, the CPU 110 of the controller 100 determines whether or not the JACKPOT has been won in the multi-feature distribution lottery process of step S2223 (step S2225).

When the CPU 110 of the controller 100 determines that the JACKPOT has not been won in the determination process of step S2223 (NO), the special payout ratio won in the multi-feature distribution lottery process is stored in the RAM 130 (step S2227), and this subroutine is stored. finish.

When the CPU 110 of the controller 100 determines that the JACKPOT has been won in the determination process of step S2223 (YES), the JACKPOT payout won in the multi-feature distribution lottery process is added (step S2229), and 1 is added to the number of JACKPOT winnings. (Step S2231), the process returns to step S2221. As described above, the multi-feature distribution lottery table is selected according to the number of JACKPOT wins.

<<< Overview of Skill Game >>>
As described above, in the free game, when the player selects the skill game, the skill game is executed. FIG. 26 is a time chart showing a rough flow of the skill game.

First, when the unit game starts, the stop symbol lottery process is executed in step S1921 of FIG. 19 to determine the stop symbol. Based on the stop symbols, the specific symbols are arranged in a predetermined arrangement (“○○ × ○○” in FIG. 26) along the valid payline. In addition, "○" indicates a specific symbol, and "x" indicates a symbol other than the specific symbol. As described above, the predetermined sequence is an incomplete sequence immediately before the final state in which the winning combination is established.

Next, in step 2123 of FIG. 19, the skill chance lottery process is executed and the skill chance is won.

Next, scrolling of the video reels 410a to 410e starts, and after a predetermined time elapses, all the video reels 410a to 410e stop. When the video reel 410 is stopped, a predetermined sequence of specific symbols "○○ × ○○" is stopped and displayed in the symbol display area 400 along a valid payline. In this example, the symbol of the video reel 410c is not a specific symbol.

Next, the skill game is started, and only the video reel 410c for which the specific symbol is not stopped and displayed is re-scrolled. The player operates the SPIN button 330 so that the specific symbols are lined up along the valid payline.

Next, by the player's stop operation, the video reel 410c is stopped, stopped and displayed in the symbol display area 400, the specific symbols are lined up along the valid payline, the winning combination of the specific symbols is established, and the corresponding payout is established. Is paid out and the skill game ends and the unit game ends.

<<< Settlement processing >>>
When the normal game is being played, the ticket can be printed out and settled in any of the base game, the high-probability game 1, the high-probability game 2, the high-probability game 3, and the high-probability game 4. On the other hand, when a free game is being played, it is not possible to settle any of the free game A, the free game B, and the free game C.

<<< Display of dividends earned in free games >>>
When the free game ends, the earned payouts are displayed on the lower display 210, the upper display 220, and the like in any of the free game A, the free game B, and the free game C. Further, in the case of continuing the first transition or continuing the second transition described above, when the transition to the free game A, the free game B, or the free game C is performed, the number of transitions is counted and the free game A, the free game A, is free. When the game B and the free game C are completed, the acquired dividends are added to the total number. The total number of dividends earned when shifting from high-probability game 1, high-probability game 2, high-probability game 3, and high-probability game 4 to the base game without being able to move to free game A, free game B, and free game C By displaying the number of transitions on the lower display 210, the upper display 220, etc., it is possible to show the player the total number of dividends obtained by the continuation of the first transition and the continuation of the second transition, and the number of continuations. .. By initializing the number of transitions when transitioning from the high-probability game 1, the high-probability game 2, the high-probability game 3, and the high-probability game 4 to the base game, the continuous number of times can be cleared.

<<< Game migration process >>>
FIG. 27 is a flowchart showing the game transition process. This process is called and executed in step S628 of the normal game process of FIG.

First, the CPU 110 of the controller 100 determines whether or not to shift to the base game (step S2711).

When the CPU 110 of the controller 100 determines that it does not shift to the base game (NO), it immediately terminates this subroutine.

On the other hand, when the CPU 110 of the controller 100 determines that the game shifts to the base game (YES), it determines whether or not the value of the free game continuation counter is greater than 0 (step S2713).

The CPU 110 of the controller 100 immediately terminates this subroutine when it determines that the game shifts to the base game (YES) and when it determines that the value of the free game continuation counter is 0 or less (NO). That is, if the free game has not continued, this subroutine is immediately terminated.

When the CPU 110 of the controller 100 determines that the game shifts to the base game (YES), the value of the free game continuation counter is determined to be greater than 0 (YES), that is, the free game has been continued until now. When the game shifts to the base game without being able to continue the new free game, the total number of credits paid out for the continuation of the free game is displayed on the lower display 210 (step S2715). By displaying the total number of credits paid out in the continuous free game, the player can visually recognize all the credits paid out in the continuous free game.

Next, the CPU 110 of the controller 100 initializes the free game continuation counter (step S2717), initializes the total number of free game continuation payout credits (step S2719), and ends this subroutine.

<<< JACKPOT accumulation processing >>>
FIG. 28 is a flowchart showing the JACKPOT accumulation process. This process is called and executed in step S725 of the BET process / SPIN button process of FIG. 7. The JACKPOT accumulation process of FIG. 28 is commonly executed in both the normal game and the free game.

First, the CPU 110 of the controller 100 calculates an additional value to be added to the JACKPOT accumulated dividend (step S2811).

Next, the CPU 110 of the controller 100 adds an added value to the JACKPOT accumulated dividend and stores it in a predetermined storage area (step S2813), and ends this subroutine.

<<< JACKPOT processing >>>
The JACKPOT accumulation process is executed by the process of FIG. 28 described above. By the JACKPOT accumulation process, a predetermined accumulated value (accumulated credit number) is accumulated in the JACKPOT accumulated dividend at a predetermined timing, for example, every time a unit game is played. Further, when the predetermined conditions are satisfied, the accumulated JACKPOT accumulated dividend is paid out. For example, in the present embodiment, as shown in FIG. 18, when the JACKPOT is won, the JACKPOT accumulated dividend is paid out.

The accumulated value can be made constant regardless of the BET multiple. That is, the accumulated value can be kept constant regardless of whether the minimum BET (for example, the "BET x 1" button 320a is operated) or the maximum BET (for example, the "BET x 5" button 320e is operated). In this case, if you win JACKPOT while playing the game with the minimum BET, you can make the payout credit larger than the input credit, and it tends to be more advantageous than when you are playing the game with the maximum BET. , Unfairness may occur.

For this reason, by adjusting the winning probability so that it is easier to win the JACKPOT when playing the game with the maximum BET than when playing the game with the minimum BET, unfairness due to the BET multiple can be reduced. It can be resolved.

However, in the case of such a configuration, it is necessary to change the winning probability of JACKPOT according to the BET multiple. Further, when the winning of JACKPOT is determined by the result of the symbol lottery process, it becomes necessary to switch the symbol table according to the BET multiple. For this reason, the processing becomes complicated, and it becomes necessary to store a large number of symbol tables in the storage device 140. In the following, a process that can make the probability of winning JACKPOT constant regardless of the BET multiple will be described.

<< JACKPOT accumulation process 1 >>
The ratio of the accumulated value accumulated in the JACKPOT accumulated dividend is changed according to the BET multiple. FIG. 29A is a conceptual diagram showing a storage area of the RAM 130 for storing the JACKPOT accumulated dividend. A1 to A5 shown in FIG. 29A are storage areas of the RAM 130 for storing the JACKPOT accumulated dividend. × 1 to × 5 shown in FIG. 29A indicate a BET multiple. The numerical value shown in each of the cells of FIG. 29A is the ratio of the accumulated value.

Regardless of the BET magnification of × 1 to × 5, predetermined accumulated values are accumulated in all the storage areas A1 to A5. When the BET magnification is × 1, the accumulated values corresponding to the ratios are accumulated in all of the storage areas A1 to A5 corresponding to the BET magnification of × 1. Similarly, when the BET magnification is × 3, the accumulated values corresponding to the ratios are accumulated in all of the storage areas A1 to A5 corresponding to the BET magnification of × 3. In this way, the ratio of accumulation in the storage areas A1 to A5 is changed according to the BET magnification, and the accumulated value is accumulated.

Specifically, when the BET magnification, which is the minimum BET, is × 1, the largest percentage (0.6%) of accumulated values is accumulated in the storage area A1, and the remaining storage areas A2 to A5 are small. The accumulated value of the ratio (0.1%) is accumulated. Further, when the BET magnification, which is the maximum BET, is × 5, the largest ratio (2.6%) of accumulated values is accumulated in the storage area A5, and a small ratio (0) is accumulated in each of the remaining storage areas A1 to A4. 6.6%) accumulated value is accumulated.

If JACKPOT is won when the BET ratio is x1, all JACKPOT accumulated dividends in the storage area A1 are paid out (R11). If JACKPOT is won when the BET ratio is × 2, all JACKPOT accumulated dividends in the storage areas A1 and A2 are paid out (R12). If JACKPOT is won when the BET ratio is × 3, all JACKPOT accumulated dividends in the storage areas A1 to A3 are paid out (R13). If JACKPOT is won when the BET ratio is × 4, all JACKPOT accumulated dividends in the storage areas A1 to A4 are paid out (R14). If JACKPOT is won when the BET ratio is × 5, all JACKPOT accumulated dividends in the storage areas A1 to A5 are paid out (R15).

By doing this, it is possible to eliminate unfairness while keeping the probability of winning JACKPOT constant.

You can also do the following: FIG. 29B is a conceptual diagram showing a storage area of the RAM 130 for storing the JACKPOT accumulated dividend. A1 to A5 shown in FIG. 29B are storage areas of the RAM 130 for storing the JACKPOT accumulated dividend. × 1 to × 5 shown in FIG. 29B indicate BET multiples. The numerical value shown in each of the cells of FIG. 29B is the ratio of the accumulated value.

When the BET magnification is × 1, the accumulated value corresponding to the ratio (1%) is accumulated only in the storage area A1 of the BET magnification × 1. When the BET magnification is × 2, the accumulated value corresponding to the ratio (2%) is accumulated only in the storage area A2 of the BET magnification × 2. When the BET magnification is × 3, the accumulated value corresponding to the ratio (3%) is accumulated only in the storage area A3 of the BET magnification × 3. When the BET magnification is × 4, the accumulated value corresponding to the ratio (4%) is accumulated only in the storage area A4 of the BET magnification × 4. When the BET magnification is × 5, the accumulated value corresponding to the ratio (5%) is accumulated only in the storage area A5 of the BET magnification × 5.

If JACKPOT is won when the BET ratio is x1, the JACKPOT accumulated dividend in the storage area A1 is paid out (R21). If JACKPOT is won when the BET ratio is × 2, the JACKPOT accumulated dividends of the storage areas A1 and A2 are paid out (R22). If the JACKPOT is won when the BET ratio is × 3, the JACKPOT accumulated dividend of the storage areas A1 to A3 is paid out (R23). If JACKPOT is won when the BET ratio is × 4, the JACKPOT accumulated dividends in the storage areas A1 to A4 are paid out (R24). If JACKPOT is won when the BET ratio is × 5, the JACKPOT accumulated dividends in the storage areas A1 to A5 are paid out (R25).

By doing this, it is possible to eliminate unfairness while keeping the probability of winning JACKPOT constant.
