Description

  The present invention relates to a slot machine, and more particularly to control to a specific gaming state based on derivation of a specific display result.

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

  The types of winning combinations include small roles, bonuses, and replays. Here, in the winning of a small role, the player can obtain a profit that a predetermined number of medals are paid out for each type of small role. In the bonus winning, the player can obtain a profit that the next game is shifted to a gaming state advantageous to the player, such as a regular bonus or a big bonus. In the replay winning, it is possible to obtain a profit that the next game can be performed without consuming new medals for setting the number of bets.

  In order for a winning combination including a bonus combination to occur, generally, a winning flag must be set by winning an internal lottery performed in advance (usually when a start lever is operated). Here, using the fact that the player can obtain the benefit of not having to consume medals for setting the number of bets by winning a replay, the normal game state is a role other than replay by a predetermined number of games. There was a slot machine that defined RT (Replay Time) that increases the replay winning probability without changing the winning probability as a specific gaming state other than a special gaming state called a bonus such as a big bonus or a regular bonus (for example, , See Patent Document 1).

Japanese Patent Laying-Open No. 2005-131323 (paragraph 0034)

  Although there are things that are not related to the derivation of the display result of the variable display device, such as the end of the big bonus, as an opportunity to control the gaming state to RT, the RT entry pattern was derived to the variable display device There was also an opportunity. When the gaming state is controlled to RT triggered by the derivation of the RT entry symbol, if the result of the internal lottery corresponds to the RT entry symbol, the RT derivation symbol will always be derived regardless of the gaming state ( However, there is a case where the operation procedure of the stop button is added as a condition), and the game is not sharp as an opportunity to control the gaming state to RT.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a slot machine that produces sharpness at an opportunity for deriving a specific display result accompanying a transition to a specific gaming state such as RT.

To achieve the above object, a slot machine according to the present invention includes:
A game can be started by setting a predetermined number of bets for one game using a game value (medal), and a variable display device (variable display device 2) that displays a plurality of types of identification information in a variable manner. ) Is a slot machine (slot machine 1) in which one game is completed when a display result is derived and a winning can be generated according to the display result derived to the variable display device,
A fluctuation start control means (step S204) for starting the fluctuation display of the identification information in the variable display device when a predetermined fluctuation start condition is satisfied;
Allowing the generation of multiple types of prizes including a predetermined special prize (challenge bonus) and a special prize (single bonus) different from the special prize before the display result of the variable display device is derived for each game Pre-decision means (step S3) for deciding whether or not to do;
Derivation control means (steps S205, S208, S215) for performing control for causing the variable display device to derive a display result according to the determination result of the prior determination means;
Special gaming state control means (step S311) for controlling the gaming state to a special gaming state that is more advantageous to the player than the normal gaming state when the special winning occurs;
In the special gaming state, when it is determined by the pre-determining means that the generation of the special prize is permitted, the special gaming state that ends the special gaming state after the end of the game in which the special prize is allowed to occur. Ending means (step S415),
The special gaming state ending means is a predetermined condition special gaming state ending means for ending the special gaming state when a predetermined condition different from the determination to allow the occurrence of the special prize is established in the special gaming state. (Step S414 (Clear flag in CB))
The pre-determining means can determine that the occurrence of the special prize is permitted in both the normal gaming state and the special gaming state,
The derivation control means includes
Normal derivation control means (steps S205 and S215) for performing control for deriving a special display result for generating the special prize when it is determined that the special prize is allowed to be generated in the normal gaming state;
Special derivation control means for performing control for deriving the special display result and / or a predetermined specific display result (RT symbol) when it is determined that the occurrence of the special prize is allowed in the special gaming state Steps S205, S208, S215)
The slot machine is
A specific game state control means (step S317) for controlling the game state to a specific game state (RT1) advantageous to a player different from the special game state when the specific display result is derived ;
The specific display result is not derived even if it is determined that the occurrence of the special prize is allowed in the normal gaming state, and it is determined that the occurrence of the special prize is allowed in the special gaming state. And is controlled to the specific gaming state upon completion of the special gaming state by deriving the specific display result .

  In the slot machine, it is determined whether or not the special winning is permitted in the normal gaming state and the special gaming state. Here, when it is determined that the special winning is permitted in the special gaming state, the specific display result can be derived in addition to the special display result for generating the special winning. Then, when the specific display result is derived to the variable display device, the special game state is controlled to a specific game state advantageous for a different player. As described above, it is possible to derive the specific display result by determining that the special prize is allowed to be generated only when the gaming state is in the special gaming state, and the specific gaming state based on the derivation of the specific display result. By controlling the gaming state, the opportunity to be controlled to the specific gaming state is generated.

  In the slot machine, the specific game state is, for example, a replay accompanied by a re-game that allows the pre-determining means to play the next game without using the game value for setting the bet amount. It is possible to set a re-game high probability state in which the probability of determining that the game winning is permitted is higher than the normal game state.

  In addition, the special prize may be a prize accompanied by a transition to a special game state that is advantageous for a player who is different from the special game state and the specific game state. This special gaming state can be a gaming state that ends with only one game. For example, the probability that the pre-determining means decides to allow the occurrence of a small prize winning with a payout of the gaming value is set. The gaming state can be set higher than the normal gaming state.

  In addition, the specific display result may be a display result derived when the special display result cannot be derived when it is determined that the special winning is allowed. Here, the specific display result may be a display result that does not generate a prize. Further, when it is determined to allow the occurrence of the special prize in the special gaming state, when it is also determined to allow the generation of the predetermined type of small prize, the predetermined type of small prize is awarded. The small combination display result to be generated can be used. The specific display result may be a special display result derived to a specific winning line among the plurality of winning lines when a plurality of winning lines are set in the variable display device. Further, the specific display result may be a display result derived only when it is determined that the special winning is allowed in the special gaming state.

  Further, the derivation control means performs control for deriving a display result according to the determination result of the pre-decision means when the stop condition for stopping the variation display of the identification information is satisfied. Deriving the display result according to the determination result on condition that the display state of the identification information is in a state in which the display result according to the determination result of the prior determination means can be derived, and the stop condition is satisfied Depending on the display state of the identification information at the time, the display result corresponding to the determination result of the prior determination means may not necessarily be derived.

In addition, the special game state ending means at the predetermined condition, when the number of game values given to the player in the special game state reaches a predetermined specified number, The gaming state may be terminated .

Furthermore, in the slot machine, the special gaming state is ended based on the establishment of a predetermined condition , or is ended based on the determination that the special winning is permitted (here, the specific display result is derived). The player is paying attention to whether or not the game is controlled to a specific game state), so that the interest of the game can be improved.

In the above slot machine ,
The special game state ending means at the predetermined condition terminates the special game state when the predetermined condition is satisfied in the special game state, and the second specific specification is different from the specific game state in terms of the advantage for the player. The game state (RT2) may include second specific game state control means (step S414 (RT2 counter ← 100)) for controlling the game state.

In this case, the special game state is ended based on the establishment of a predetermined condition (in this case, controlled to the second specific game state having a different advantage from the specific game state), or a special prize is allowed to be generated. Since the player pays attention to whether or not the game is ended (here, the specific display result may be derived and controlled to the specific game state), Can be improved.

  The second specific gaming state is such that when the specific gaming state control means controls the replaying high probability state as the specific gaming state, the pre-determining means is in the normal gaming state. A probability state during replay in which the probability of determining whether to allow the occurrence of the replay prize is lower than the high probability state of replay as the specific gaming state, although the probability is higher than the probability of determining that the occurrence of the replay is allowed It is good. Further, the second specific gaming state has an advantage over the normal gaming state by a number of games smaller than the predetermined number of games when the specific gaming state continues a state advantageous for the player by a predetermined number of games. It is also possible to continue the state.

The slot machine is
In addition, according to the player's operation, it further comprises stop operation means (stop buttons 12L, 12C, 12R) for instructing to derive the display result of the variable display device,
The derivation control means is a control for causing the variable display device to derive a display result according to an operation procedure of the stop operation means and a determination result of the prior determination means when the stop operation means is operated. (Steps S205, S208, S215). In this case,
When it is determined that the special winning state is allowed to occur in the special gaming state, the special derivation control means determines that the stop operation means performs a specific operation procedure (four “7” in the lower stage of the left reel 3L). The specific display result may be derived on the condition that the stop button 12L is operated in a state where the button is positioned and the stop button 12L is not operated).

  In this case, it is not only determined that the special winning is allowed in the special game state, but the specific display result is not derived unless the player operates the stop operation means in a specific operation procedure. Thus, the interest of the game can be improved by causing the player to perform technical intervention in the control from the derivation of the specific display result to the specific game state.

Here, the slot machine further comprises time measuring means (step S203) for measuring a time elapsed since the time measurement start condition that can be satisfied after the predetermined variation start condition is satisfied,
The derivation control means includes time derivation control means (step S208) for causing the variable display device to derive a display result when the timing means measures a predetermined time without operating the stop operation means. In
The specific operation procedure may include not operating the stop operation unit (stop button 12L) until the time measuring unit measures the predetermined time.

  In this case, if the player is willing to derive the specific display result, the specific display result can be derived with a simple technical intervention that does not actively operate the stop operation means. It becomes possible to control the gaming state to the specific gaming state regardless of the skill of the player.

The slot machine is
Allowable notification means for performing a predetermined notification at a predetermined ratio when it is determined that the special winning is permitted in the special gaming state and when it is not determined that the special winning is permitted. (Liquid crystal display 4: Step S505) may be further provided. In this case,
The derivation control means, when it is determined to allow the occurrence of the special prize in the special gaming state, the special prize until the control for deriving the display result of the variable display device is finally performed. It is possible to perform the same control as when it is not determined to allow the occurrence of.

  In this case, it is determined by the notification from the permission notification means that it is determined that the special winning state is allowed to occur in the special gaming state, that is, the player expects that the specific display result is derived and controlled to the specific gaming state. It will be possible to further improve the interest of the game. Here, even if it is a case where the occurrence of a special prize is not permitted, the fact that a special prize is allowed to be generated in the variation display mode of the identification information until the control for deriving the display result is finally performed. Since there is no difference from the case where it is determined, the player does not know whether or not it is determined to allow the generation of the special prize, and the player's expectation for the admission of the special prize is not lost.

The CPU 111 controls the reel motors 3ML, 3MC, and 3MR via the reel relay board 103 with reference to a winning flag set in the RAM 112 by internal lottery described later and a table selected based on the gaming state, Stop 3L, 3C, 3R. An effect control board 102 is further connected to the game control board 101 via an effect relay board 106.

  The effect relay board 106 is a board provided to ensure one-way information transmitted from the game control board 101 to the effect control board 102. The effect relay board 106 does not check the game control board 101 and the effect control board 102 by checking this state, and an illegal signal (especially an external input to the effect control board 102 is input to the control unit 110 of the game control board 101). It is possible to check whether or not a modification has been made such that a signal is input).

  The effect control board 102 is a sub-side control board that controls the execution of effects in the slot machine 1, and is equipped with a control unit 120 including a one-chip microcomputer including a CPU 121, a RAM 122, a ROM 123, and an I / O port 124. Yes. In addition, the random number generation circuit 125 and the sampling circuit 126 are mounted, and the CPU 121 obtains the value counted by the random number generation circuit 125 by the sampling circuit 126, so that the hardware random number function similar to that of the game control board 101 is obtained. Is forming. It also has a software random number function by interrupt processing.

  The CPU 121 executes a program (described later) stored in the ROM 123 to perform processing related to the execution of the effect, and controls each circuit in the effect control board 102 and each circuit connected thereto. The performance is performed based on a command received from the game control board 101 via the I / O port 124. The RAM 122 is used as a work area when the CPU 121 executes a program. The ROM 123 stores programs executed by the CPU 121 and fixed data. The effect data stored in the ROM 123 will be described later. The I / O port 124 inputs and outputs control signals to and from each circuit connected to the effect control board 102.

  The effect control board 102 is connected with game effect lamps 75A to 75M, a liquid crystal display 4, speakers 7L, 7R, and 7U, a fluorescent lamp 6, a weight lamp 61, and a bonus notification lamp 66. A reel lamp 3LP is connected via a reel lamp relay substrate 104. The control unit 120 of the effect control board 102 performs these effects by controlling these parts.

  The reel relay board 103 relays between the game control board 101, the external output board 105 and the reel unit 3. The reel relay substrate 103 is also connected with a full sensor 90, and its detection signal is input. The full tank sensor 90 is provided inside the slot machine 1 and detects that the medals in the overflow tank storing the medals overflowed from the hopper 80 are full.

  The reel lamp relay board 104 relays between the effect control board 102 and the reel unit 3. The external output board 105 is connected to an external device such as a hall management computer, and receives a big bonus medium signal, a challenge bonus medium signal, a regular bonus medium signal input from the game control board 101 via the reel relay board 103, The reel control signal, stop switch signal, medal IN signal, medal OUT signal, and winning status signal are output to the external device.

  In the slot machine 1, a winning is awarded when the winning symbols are arranged on any winning line of the variable display device 2. The types of winning combinations are determined according to the gaming status, but can be broadly divided into special roles with transition to special gaming status (regular bonus, big bonus, challenge bonus) and medal payout. There are a small role and a re-playing role that allows the next game to be started without setting the bet amount. FIG. 4A is a diagram for explaining the combination of the types of winning combinations in the slot machine 1 and the symbols in the variable display device 2.

  The single bonus (SB) is won when a combination of “JAC-watermelon-watermelon” is arranged in any of the winning lines in the normal gaming state, RT1 or RT2, or the challenge bonus. When a single bonus is won, the game state shifts to a single bonus for the next one game. When the gaming state is the single bonus, the single bonus medium flag is set in the RAM 112, and the winning combination probability (especially bell) of the small role becomes higher than the normal gaming state.

  The “JAC” for the left reel 3L and the “watermelon” for the middle and right reels 3C, 3R are all arranged at intervals of 5 frames or less, so when a single bonus is won in the normal gaming state, be sure to A single bonus will be awarded, but when the game state is a challenge bonus, the number of frames drawn on the left reel 3L is limited to a maximum of one frame, so that the operation of the stop buttons 12L, 12C, 12R will be described later. Depending on the procedure, it is not always possible to win a single bonus.

  The regular bonus (RB) is awarded when the combination of “BAR-BAR-BAR” is aligned on either of the winning lines in the normal gaming state, RT1 or RT2. When the regular bonus is won, the gaming state shifts from the normal gaming state to the regular bonus. The regular bonus ends when 12 games are consumed, or when 8 games are won (any kind of combination is possible), whichever comes first. While the game state is in the regular bonus, the regular bonus medium flag is set in the RAM 112 (including the case where it is provided during the big bonus described below). The regular bonus gameplay is the same as the single bonus except that the game is continued for a plurality of games without ending one game.

  The big bonus (BB) is awarded when the combination of “7-7-7” is aligned on either of the winning lines in the normal gaming state, RT1 or RT2. When the big bonus is won, the gaming state shifts to the big bonus. In the big bonus, the regular bonus described above is repeatedly provided until the end. While the gaming state is the big bonus, the big bonus medium flag is set in the RAM 112. The big bonus ends when the number of medals paid out to the player exceeds 345. After the end of the big bonus, all operations of the player are invalid except for the payment of credits, and the game is controlled to a freeze state in which the game cannot be progressed for a certain period of time.

  The challenge bonus (CB) is awarded when the combination of “BAR-7-7” is aligned on either of the winning lines in the normal gaming state, RT1 or RT2. When a challenge bonus is won, the gaming state shifts to a challenge bonus. While the gaming state is in the challenge bonus, a challenge bonus medium flag is set in the RAM 112. When the gaming state is the challenge bonus, the maximum stop delay time for the left reel 3L is shortened from the usual 190 milliseconds to 75 milliseconds, and only one frame can be drawn, but depending on the result of the internal lottery It is possible to win watermelons, bells, and cherries (that is, the winning flags for these roles are set regardless of the internal lottery).

  However, even when the game state is the challenge bonus, the single bonus may be won by internal lottery, and when the single bonus is won, the single reel is within the maximum stop delay of 75 milliseconds for the left reel 3L. If it is possible to win a bonus, the single bonus will be given priority over watermelon, bell, and cherry. If you cannot win a single bonus when you win a single bonus, and you cannot win other small roles, you can use an RT symbol (7-watermelon-watermelon) that is not defined as a winning role. Sometimes it can be derived.

  For example, when the left reel 3L is stopped as the first reel (the first reel to be stopped), the upper side is the same as when the stop button 12L is operated at the timing when the fourth “7” is in the lower stage. Since “JAC” can be derived to any one of the middle and lower stages, and “watermelon” can be derived on the winning line from which the middle and right reels 3C and 3R are derived, a single bonus is awarded. When the stop button 12L is operated at the timing when the fourth "7" is in the lower stage, the "bell" can be derived to the upper stage, and the "bell" is displayed on the winning line from which the middle and right reels 3C and 3R are derived. Can be derived, so win the bell.

  When the left reel 3L is stopped as the third reel (the third reel to be stopped), the single bonus winning is given priority, so “watermelon” is placed on the winning line for the middle and right reels 3C and 3R. To temper. When the stop button 12L is operated at the timing when the second to fourth "7" is positioned on the winning line where the "watermelon" is tempered, the "7-watermelon-watermelon" combination can be derived on the winning line. It will be a thing. However, when the left reel 3L is stopped as the second reel (the second reel to be stopped), even if “7” and “watermelon” stop side by side on the pay line, they become the third reel. Alternatively, a lost symbol that is not an RT symbol is derived by controlling the right reels 3C and 3R.

  However, if the stop buttons 12L, 12C and / or 12R are not operated for a predetermined time (for example, 30 seconds) from the start of rotation of the reels 3L, 3C, 3R, the rotation of the reels that have not been stopped is automatically stopped. Will be. In the case of automatic stop, there is no limit on the maximum stop delay time of the reels 3L, 3C, 3R. In the case of automatic stop, the winning combination is not derived regardless of the gaming state and the setting status of the winning flag, but the RT symbol is not defined as a winning combination, so the single bonus is won in the gaming state of the challenge bonus. When the rotation of the reels 3L, 3C, and 3R is automatically stopped during the operation, the RT symbol is derived when only the left reel 3L remains and is automatically stopped.

  When the single bonus is won in the internal lottery, the challenge bonus ends after waiting for the result of the game to be derived to the variable display device 2 (that is, the challenge bonus of the game that has won the single bonus is still Will remain in the gaming state). In this case, the gaming state is controlled to RT1 after the end of the challenge bonus. The challenge bonus is also ended when the number of medals paid out to the player exceeds 238. In this case, the gaming state is controlled to RT2 after the end of the challenge bonus.

  Even if a regular bonus, a big bonus, or a challenge bonus is won in an internal lottery that will be described later, if the stop buttons 12L, 12C, and 12R are not operated according to an appropriate operation procedure that makes it possible to win these roles, There will be no winnings. Of course, if you don't win any of these roles without operating in the proper operating procedure, you will be able to derive only when you win these roles (in terms of winning, ), Or chances that can be derived when these roles are won or not (in terms of winning, lost) may be derived. In the display result of the losing, there is a losing that can be derived only when the regular bonus, the big bonus, and the challenge bonus are not won.

  The watermelon is awarded when a combination of “watermelon-watermelon-watermelon” is aligned on any winning line in any gaming state, and 15 medals are paid out. “Watermelons” for the reels 3C and 3R are arranged at intervals of 5 frames or less, but since only one “watermelon” is arranged for the left reel 3L, the watermelons in the gaming state other than the challenge bonus Even if winning is won, depending on the operation timing of the stop button 12L, the watermelon is not necessarily won.

  The bell is awarded when a combination of “bell-bell-bell” is arranged on any winning line in any gaming state, and five medals are paid out. Since “bells” are arranged at intervals of 5 frames or less for all of the reels 3L, 3C, and 3R, when a bell is won in a gaming state other than the challenge bonus, the bell is always won.

  Cherry is awarded when the symbol “Cherry” is derived on any of the winning lines for the right reel 3R in any gaming state, and two medals are paid out per winning line. When “cherry” stops at the upper or lower stage of the right reel 3R, the derivation is made on two pay lines, so that a total of four medals are paid out.

  Replay is awarded when the combination of “JAC-JAC-JAC” is aligned on either of the winning lines in the normal gaming state, RT1 or RT2. In other gaming states, even if this combination is complete, there will be no replay prize. When winning a replay, there is no payout of medals, but the next game can be started again without setting the number of bets, so three medals corresponding to the number of bets 3 that became unnecessary in the next game are paid out. This is essentially the same as. Since “JAC” is arranged at intervals of 5 frames or less for all of the reels 3L, 3C, and 3R, when a replay is won, the replay is always won.

  Note that RT1 controlled by derivation of the RT symbol and RT2 that is terminated after the challenge bonus is ended without winning the single bonus are both gaming states in which the winning probability of replay is higher than the normal gaming state. RT1 has a higher replay win probability. In RT1, since the replay winning probability is extremely high, the expected value of the number of medals to be paid out for the small role won in the internal lottery with respect to the number of medals inserted by the player for setting the bet number The payout rate of medals calculated as a percentage exceeds 1, and it is expected that more medals can be obtained at RT1 than the number of medals that can be expected with a single bonus. On the other hand, in RT2, the replay winning probability is higher than in the normal gaming state, and the medal payout rate is higher than in the normal gaming state, but the medal payout rate does not exceed 1.

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

  FIG. 4B is a view showing a winning combination table by gaming state. The winning combination table according to gaming state is stored in advance in the ROM 113 and is used to determine the winning combination determined in the internal lottery. The registered content of the winning combination table according to gaming state depends on the gaming state. It shows the role that has been determined. In the game state of each game, a combination that is a lottery target is referred to. Here, a plurality of winning combinations may be subject to lottery at the same time.

When the gaming state is a single bonus or a regular bonus (including a case in which the bonus is provided during a big bonus), watermelon, bell, and cherry are sequentially read out as the internal lottery target roles. When the gaming state is a challenge bonus, only a single bonus is sequentially read out as a target combination for internal lottery. When in the normal gaming state, RT1 or RT2, a single bonus, regular bonus, big bonus, challenge bonus, watermelon, bell, cherry, and replay are sequentially read out as the internal lottery target roles.

  In the internal lottery, the number of judgment values registered for each gaming state and set value for the target part of the internal lottery is sequentially added to the random number for internal lottery. It is determined that the winning role is won. If the winning combination is determined, the winning flag of the combination is set in the RAM 112. The number of determination values is registered in a role table stored in the ROM 113 in advance.

  Note that the number of replay determination values in RT2 is larger than the number of replay determination values in the normal gaming state, and the number of replay determination values in RT1 is larger than the number of replay determination values in RT2. Thereby, the replay winning probability in RT2 is higher than that in the normal gaming state, and the replay winning probability in RT1 is further higher than that in RT2. Note that the number of determination values of the bell in the normal gaming state, RT1, RT2 is relatively small, and the winning probability in the normal gaming state is only about 1/6. On the other hand, the number of determination values of the bell in the single bonus and regular bonus (including the case where the bonus is provided during the big bonus) is relatively large, which is 5/6 or more. In the single bonus or regular bonus, the winning probabilities of watermelon and cherry are combined to win some kind of small role in most games.

  Next, storage of results of internal lottery and management of winning combinations will be described. FIG. 5 is a diagram for explaining an area for storing an internal lottery result and an area for managing winnings. That is, in the RAM 112, the winning flag storage register (2 bytes) shown in FIG. 5A, the special combination temporary storage register (1 byte) shown in FIG. 5B, and the general combination shown in FIG. A temporary storage register (1 byte), an index search register (1 byte) shown in FIG. 5D, and a winning flag storage register (2 bytes) shown in FIG. 5E are provided.

  Here, the winning flag storage register and the winning flag storage register are always cleared at the end of one game, but the special role temporary storage register is cleared by winning a special role and is cleared every game. Absent. In addition, the bits that are “unused” in the winning flag storage register and the winning flag storage register are bits that do not correspond to any combination, and the value thereof is always 0 (provided that the illegal winning determination is made) Except when the data in the winning flag storage register is inverted).

  The winning flag of the lottery role determined to be won in the internal lottery is first set in the winning flag storage register. Here, the fact that the winning flag is set means that the corresponding bit changes from 0 to 1. For example, when the regular bonus is won, the regular bonus winning flag in the most significant bit of the upper byte of the winning flag storage register is set. When a cherry is won, a cherry winning flag is set in the winning flag storage register.

  When the winning flag for a special role (regular bonus, big bonus, challenge bonus or single bonus) is set in the winning flag storage register by internal lottery, the value corresponding to the special role for which the winning flag is set is the special role temporary storage register Is written to. If data indicating that the special combination is won (that is, data other than 0) is written in the special combination temporary storage register in the normal gaming state, the special combination lottery is not performed and the contents are not rewritten. In this case, the regular bonus winning flag, the big bonus winning flag or the challenge bonus winning flag is set in the winning flag storing register according to the value of the special role temporary storing register (in a game in which the single bonus winning flag is set). Since the special combination temporary storage data is erased in the game, the single bonus winning flag is not set according to the value of the special combination temporary storage register in the next game).

  In addition, when the winning flag of the general combination (small role or replay) is set in the winning flag storage register by internal lottery (in addition, in the case of the challenge bonus, all kinds of small role winning flags are stored in the winning flag storage register regardless of the lottery. When set to), a numerical value corresponding to the general combination for which the winning flag is set is written into the general combination temporary storage register. The data in the general combination temporary storage register is overwritten and updated for each game according to the general combination winning flag set in the lower byte of the winning flag storage register according to the result of the internal lottery in each game. That is, data corresponding to the result of the internal lottery in the previous game is not written here.

  In the index search register, data in the special role temporary storage register is written in the upper 4 bits, and data in the general role temporary storage register is written in the lower 4 bits. It corresponds directly to the data in the flag storage register. When a stop control table to be described later is created, a table index stored in the ROM 113 is referred to according to the data in the index search register.

  The winning flag storing register has the same configuration as the winning flag storing register, and if a display mode of a winning combination is derived on any winning line as a display result of the variable display device 2, it corresponds. A winning flag is set. Again, the winning flag is set when the corresponding bit changes from 0 to 1. For example, when a symbol combination of “BAR-BAR-BAR” is derived on any winning line, a regular bonus winning flag is set in the winning flag storage register. When the symbol combination “ANY-ANY-Cherry” is derived, a cherry winning flag is set in the winning flag storage register.

  When a winning flag is set in the winning flag storage register, it is determined whether or not there is an illegal winning of a role for which no winning flag is set, using data in the winning flag storing register and data in the winning flag storing register. . Specifically, all the data of each bit of the winning flag storage register is logically inverted, and this and the data of the winning flag storage register are ANDed for each bit. If the result of the logical product operation is 0, it is determined that there has been no illegal winning, and if it is not 0, it is determined that an illegal winning has occurred.

  For example, consider a case where a replay symbol is derived on a winning line in a state where the regular bonus winning flag and the replay winning flag are set. The data in the winning flag storage register before the logic inversion is “10000000 10000000”. The data in the winning flag storage register after examining the display result of the variable display device 2 is “00000000 10000000”, and logical operation is performed for each bit with “01111111 01111111” obtained by logically inverting the data in the winning flag storage register. The result is “00000000 000000000”, which indicates that no illegal winning has occurred.

  Further, consider a case where a regular bonus symbol is derived on the winning line in a state where only the replay winning flag is set. The data in the winning flag storage register before the logic inversion is “00000000 10000000”. The data of the winning flag storage register after examining the display result of the variable display device 2 is “10000000 00000000”, and “11111111 01111111” obtained by logically inverting the data of the winning flag storage register is logically calculated bit by bit. The result is “10000000 00000000”, indicating that an illegal prize has occurred.

  Next, stop control of the reels 3L, 3C, 3R will be described. The CPU 111 refers to the table index and table creation data stored in the ROM 113 when the reel starts rotating and when the reel is stopped and the reel that is still rotating still remains. Create a stop control table for each reel. When any of the stop buttons 12L, 12C, and 12R corresponding to the rotating reel is effectively detected, the stop control table of the corresponding reel is referred to, and the referred stop control table is drawn. Based on the number of frames, control is performed to stop the rotation of the reels 3L, 3C, 3R corresponding to the operated stop buttons 12L, 12C, 12R.

  Even if the stop buttons 12L, 12C, and 12R are not operated, a reel that has not stopped even if a predetermined automatic stop time (for example, 30 seconds) has elapsed since the start of rotation of the reels 3L, 3C, and 3R The automatic stop table is created in the order of the reel 3L, the right reel 3C, and the middle reel 3R. The automatic stop table is created according to the gaming state and the winning situation, and the stop position of the corresponding reel is determined without restriction on the number of drawn-in frames. When the automatic stop table is created, control is performed to stop the rotation of the reels 3L, 3C, 3R corresponding to the created table.

  Next, stop control of the reels 3L, 3C, and 3R not based on automatic stop will be described in detail. FIG. 6 is a diagram showing a table index stored in the ROM 113. As shown in the figure, the table index stores the top address of the area where the data for table creation is stored for each internal winning situation.

  Even if the internal winning situation is different, if the same control is applied, the same address is stored as the start address of the area where the data for table creation is stored. In this case, the stop control table is created with reference to the same table creation data. Here, the table creation data is made up of drawn-in frame number data indicating the number of drawn-in frames corresponding to the stop operation position, and the address of the drawn-in frame number data to be referred to according to the reel stop status.

  The number-of-drawing frame data referred in accordance with the reel stop status indicates whether all the reels 3L, 3C, 3R are rotating, only the left reel 3L is stopped, only the middle reel 3C is stopped, or the right reel Depending on whether only 3R is stopped, left and middle reels 3L and 3C are stopped, left and right reels 3L and 3R are stopped, and middle and right reels 3C and 3R are stopped. In addition, in a situation where any of the reels 3L, 3C, 3R is stopped, it may differ depending on the stop position of the stopped reel.

  In the table creation data, the address of the drawing frame number data to be referred to is registered for each reel being rotated for each situation. The address of the number of frames to be drawn that should be referred to according to each situation can be specified based on the top address of the table creation data. It can be specified. Even if the reel stop status and the stop position of the stopped reel are different, the same address is registered as the address of the number of frames to be drawn when the same number of frames to be drawn is applied. In such a case, the same data for the number of drawn frames is referred to.

  Further, the number of drawn frames data is data that can specify the number of drawn frames for each timing when the stop operation is performed. For the reel motors 3ML, 3MC, and 3MR, stepping motors that make one round with a cycle of 168 steps (0 to 167) are used. That is, when the reel motors 3ML, 3MC, and 3MR are driven in 168 steps, the reels 3L, 3C, and 3R make one round. 21 areas (frames) divided every 8 steps (the number of steps in which one symbol moves) are defined for one reel. These areas are areas 1 to 21 from the reel reference position. A number is assigned (see FIG. 7).

  On the other hand, the number of symbols arranged on one reel is 21, and symbol numbers 1 to 21 from the reel reference position are assigned to symbols on each reel, so symbols 1 to 21 are assigned to each reel. , Area numbers 1 to 21 are assigned in order. The number of drawn frames by area number is compressed and stored according to a predetermined rule in the number of drawn frames data so that the number of drawn frames by area number can be acquired by expanding the number of drawn frames data. It has become.

  FIG. 7 is a diagram illustrating an example of the stop control table. As described above, the stop control table is created with reference to the table index and the table creation data. In the stop control table, as shown in FIG. 7, the area corresponding to each area number corresponds to the stop reference position (in this embodiment, the lower symbol area in the perspective window of the variable display device 2). ) (The number of steps to be taken when the operation of the stop button 12L, 12C, 12R is detected at the timing at which the stop button 12L, 12C, or 12R is detected). ing.

  Next, the procedure for creating the stop control table will be described. First, at the start of reel rotation, the top address of the table creation data corresponding to the internal winning situation in the game is acquired. Then, the table creation data is specified based on the acquired head address, and the address of the drawing frame number data of each reel corresponding to the state in which all the reels 3L, 3C, 3R are rotating is acquired from the specified table creation data. Then, the drawing frame number data of each reel stored at the acquired address is developed to create a stop control table for all the reels 3L, 3C, 3R.

  Also, when any one of the reels 3L, 3C, 3R is stopped or when any two are stopped, a table is created according to the top address acquired at the start of reel rotation, that is, the internal winning situation in the game. The table creation data is identified based on the start address of the data, and the address of the number of frames to be drawn in the unreacted reel corresponding to the stopped reel and the area number of the stop position of the reel is obtained from the identified table creation data. Then, the drawing frame number data of each reel stored at the acquired address is expanded to create a stop control table for the unstopped reels.

  Next, when the CPU 111 effectively detects any one of the stop buttons 12L, 12C, and 12R corresponding to the rotating reel, the control when the display result is derived to the corresponding reel will be described.

  When any of the stop buttons 12L, 12C, and 12R corresponding to the rotating reel is detected effectively, the area number of the stop operation position is based on the number of steps from the reel reference position when the stop operation is detected. And the number of drawn frames corresponding to the area number of the specified stop operation position is acquired by referring to the stop control table of the reel where the stop operation is detected. Then, control is performed to rotate and stop the reel by the number of acquired frames. Specifically, from the number of steps from the reel reference position at the time when the stop operation is detected, the number of steps from the acquired number of drawn frames until it is stopped is calculated, and the reel is rotated and stopped by the calculated number of steps. Take control. As a result, an area (stop point in the figure) corresponding to the area number corresponding to the stop position ahead of the number of frames to be drawn in from the area (stop operation point in the figure) corresponding to the area number of the stop operation position where the stop operation is detected. The vehicle stops at the stop reference position (in this embodiment, the lower symbol area).

  Further, the table index stores only one address as the start address of the table creation data storage area corresponding to one internal winning situation, and one table creation data contains one reel. Only one address is stored as the address of the storage area for the number of drawn frame data corresponding to the stop status (and the stop position of the stopped reel). In other words, the table creation data corresponding to one internal winning situation and the number-of-drawing frame data corresponding to the reel stop situation (and the stop position of the stopped reel) are uniquely determined. The created stop control table is also unique with respect to one internal winning status and the reel stop status (and the stop position of the stopped reel). Therefore, when all of the internal winning status and the reel stop status (and the stop position of the stopped reel) are the same, the reel stop control is performed based on the same stop control table, that is, the same control pattern. Will be performed.

  In addition, a value of 0 to 4 (the value of 0 or 1 for the left reel 3L in the challenge bonus) is determined as the number of drawn frames, and a maximum of 4 frames (left reel in the challenge bonus) after detecting a stop operation. It is possible to stop the reel by pulling the symbol. That is, the symbol stop position can be designated from a range of a maximum of 5 frames (a maximum of 2 frames for the left reel 3L in the challenge bonus) including the stop operation position at which the stop operation is detected.

  In addition, since it is necessary to move one frame to move the reel for one symbol, a maximum of four symbols (maximum one symbol for the left reel 3L in the challenge bonus) is pulled in after detecting the stop operation. It is possible to stop, and the symbol stop position can be designated from a range of a maximum of 5 symbols (maximum 2 symbols for the left reel 3L in the challenge bonus) including the stop operation position where the stop operation is detected.

  In addition, the table index draws the winning combination to the maximum in the range of 4 frames (maximum 1 frame for the left reel 3L in the challenge bonus) corresponding to the case where one of the roles is won. Stores the address of the data for table creation in which the number of frames to be drawn in is set so that there is no combination of roles that have not been collected, and the number of frames to be drawn in is determined so that none of the roles will be aligned in case of a loss Stores the address of the table creation data. For this reason, if one of the winning combinations is won, the winning combination is drawn in as much as possible within the range of 4 frames (maximum 1 frame for the left reel 3L in the challenge bonus), and there are no winning combinations. Thus, a stop control table in which the number of frames to be pulled in is determined is created, and reel stop control is performed.

  On the other hand, in the case of losing, a stop control table in which the number of frames to be drawn that do not have any combination is created, and reel stop control is performed. As a result, when a stop operation is performed, the symbols of the winning combination are stopped on the winning line with a drawing range of up to 4 frames (up to 1 frame for the left reel 3L in the challenge bonus). If it is possible, control is performed to align and stop, and the symbol of the winning combination is controlled to stop in a pull-in range of up to 4 frames (up to 1 frame for the left reel 3L in the challenge bonus). Will be done.

  In the table index, when a special role and a small role are won at the same time, or when a special role is won while the special role has been carried over from before the previous game (Big Bonus + Cherry, Big Bonus + Bell, etc.) , Corresponding to the case where a single bonus is won as a challenge bonus (single bonus + watermelon + bell + cherry), the maximum number of special roles won is 4 frames (maximum 1 frame for the left reel 3L in the challenge bonus) The number of draws to be drawn is set to the limit, and for the stop operation position that can not draw the winning special role within the range of up to 4 frames (up to 1 frame for the left reel 3L in the challenge bonus) 4 small plays (up to 1 for the left reel 3L in the challenge bonus) Enclosed in stores the address of the table creation data number pull frame is defined to draw the most of the stop control of the reels is performed.

  As a result, when the stop operation is performed, the symbols of the special roles won in the drawing range of up to 4 frames (up to 1 frame for the left reel 3L in the challenge bonus) are stopped on the winning line. If possible, control is performed to align and stop them, and the symbol of the special role elected in the drawing range of up to 4 frames (up to 1 frame for the left reel 3L in the challenge bonus) is drawn on the winning line. If it is not possible to do so, if the symbols of the small roles that have been elected can be aligned and stopped on the winning line within a maximum of 4 frames, the control will be performed to stop them and the characters that are not selected In the design of, the control is to be stopped in a pulling range of 4 frames (maximum 1 frame for the left reel 3L in the challenge bonus). When winning a single bonus in range bonus may be a mode of losing RT symbol is derived). That is, in such a case, priority is given to the control for aligning the special combination on the winning line over the small combination, and the small combination can be won only when the special combination cannot be drawn.

  In addition, the table index shows the maximum number of replaying players within the range of 4 frames, corresponding to the case where a replaying player is elected with a special role being carried over from before the previous game (such as big bonus + replay). The address of the table creation data in which the number of frames to be drawn is determined so as to be drawn in is stored, and reel stop control is performed. As a result, when a stop operation is performed, control is performed so that the symbols of the re-gamer are aligned and stopped on the winning line within a drawing range of up to four frames.

  “JAC” which is a symbol constituting the re-gamer is arranged at intervals of 5 frames or less for all of the reels 3L, 3C and 3R, and is always stopped at an arbitrary position within the drawing range of 4 frames. be able to. When a special game is carried over from before the previous game and a re-game player is elected, the re-game game will always be awarded regardless of the operation timing of the stop buttons 12L, 12C, 12R by the player. It will be. That is, in such a case, the control for aligning the re-games on the winning line has priority over the special game, and the re-games will always win.

  In addition, in the table index, in response to the case where all the types of small role winning flags are not set in the challenge bonus and the re-playing role is not selected, the table index is given priority from the role having a large number of payout medals (that is, , Watermelon, bell, and cherry), the number of frames to be drawn is determined so that the left reel 3L is drawn to the maximum within the range of one frame, and the middle and right reels 3C and 3R are drawn to the maximum of 4 frames. The address of the generated table creation data is stored, and reel stop control is performed.

  There is only one “watermelon” on the left reel 3L as a symbol constituting the watermelon having the largest number of payout medals. When the left reel 3L is stopped as the first reel, if the stop operation is performed at the timing when the “JAC” of No. 11 is positioned at the lower stage, the “watermelon” is drawn and stopped within the drawing range of one frame. When the stop operation is performed at the timing when the eighth “watermelon” is located in any of the upper, middle, and lower stages, the “watermelon” is stopped without performing the pull-in. As long as “watermelon” has been derived for the left reel 3L, which has become the first reel, a prize is awarded to the watermelon.

  Next, as a symbol constituting the bell with the largest number of payout medals, the “bell” of the left reel 3L has an interval between No. 1 and No. 6 of 5 frames, but the other is within 4 frames. When the left reel 3L is stopped as the first reel, one frame is pulled in except when the “watermelon” is stopped at the middle stage and when the stop operation is performed at the timing when the “JAC” No. 5 is positioned at the lower stage. Within the range, the “bell” can be stopped at any of the upper, middle and lower levels. The number of frames drawn in the middle and right reels 3C and 3R is 4, and the “bells” are arranged at intervals of 5 frames or less. Therefore, the “bell” is the first reel 3L on the left reel 3L. As long as it is derived, it will win the bell.

  When the left reel 3L as the first reel is stopped at the timing when the fifth “JAC” is positioned at the lower stage, only “JAC” or “7” is the upper, middle, or lower level within the pull-in range of one frame. Since no stop can be made at any timing, no winning combination will be won, no matter what timing the stop operation is performed on the middle and right reels 3C, 3R to be the second and third reels.

  When the left reel 3L is stopped as the second reel or the third reel, the “watermelon” is stopped first on the inner reel 3C and / or the right reel 3R (the left reel 3L is the third reel). In this case, “watermelon” is tempered on the winning line). When a stop operation is performed on the left reel 3L, which is the second reel, the “watermelon” is stopped on the middle or right reels 3C, 3R, which are the first reels, within the range of one frame on the winning line. If the "watermelon" can be pulled in and stopped, it is pulled in and stopped, and the "watermelon" is stopped. In this case, when the third reel is stopped, the watermelon is won.

  When the left reel 3L, which is the second reel, is stopped, “bell” is derived for the first reel even if “watermelon” cannot be stopped on the winning line where “watermelon” is stopped. If the “bell” can be stopped within the drawing range of one frame on the winning line where “bell” is stopped, the “bell” is stopped. In this case, when the third reel is stopped, the player wins the bell. When the operation of stopping the left reel 3L, which is the second reel, is performed, if the "bell" cannot be stopped within the range of one frame on the winning line where the "bell" has been previously stopped I won't win any combination.

  In addition, if the operation of stopping the left reel 3L, which is the third reel, is performed, if the "watermelon" can be drawn and stopped within the range of one frame on the winning line where the "watermelon" is tempered first, This will be pulled in and stopped, and the watermelon will win. If “Watermelon” cannot be drawn and stopped within the range of one frame on the winning line where “Watermelon” is tempered, no winning combination will be awarded. There is no double water pie for "Watermelon" and "Bell", so you can't win the Bell.

  In addition, in the table index, the single bonus is given priority first, and the number of medals to be paid out is the next, corresponding to the case where only the single bonus is set in the challenge bonus and all types of small bonus winning flags are set. Priority is given to larger roles (ie, watermelon, bell, and cherry), with a maximum of 1 frame for the left reel 3L and 4 frames for the middle and right reels 3C and 3R. The address of the table creation data in which the number of frames to be drawn is determined so as to be pulled in, and reel stop control is performed.

  When the left reel 3L is stopped as the first reel at a time other than the timing when the fourth “7” is positioned at the lower stage, “JAC” is derived to one of the upper, middle and lower stages within the pull-in range of one frame. This can be derived. In this case, since “watermelon” can be stopped on the winning line from which “JAC” is derived for the middle and right reels 3C and 3R, a single bonus is won. On the other hand, when the stop operation is performed at the timing when the fourth “7” is positioned at the lower stage, the first “bell” can be stopped at the upper stage within the drawing range of one frame, and this is stopped. . In this case, since the “bell” can be derived on the winning line for the middle and right reels 3C and 3R, the bell is won.

  When the left reel 3L is stopped as the third reel, “watermelon” is aligned on the winning line for the inner reel 3C and the right reel 3R. When a stop operation of the left reel 3L, which is the third reel, is performed, the “watermelon” is tempered on the inner reel 3C and the right reel 3R, and “JAC” If it can be pulled in and stopped, it is pulled in and stopped, and a single bonus is awarded.

  The “watermelon” cannot be stopped by drawing “JAC” in the range of one frame on the winning line where the “watermelon” is stopped by the tempering of the inner reel 3C and the right reel 3R, but “watermelon” is stopped. If it is possible, stop this on the winning line and make the watermelon win. Otherwise, it will be lost. However, if the stop operation is performed at the timing at which “7” of No. 2 to No. 4 is positioned on the pay line where “watermelon” is stopped for the inner reel 3C and the right reel 3R, the pay line “7” is stopped above, and the RT symbol is derived.

  Even when the left reel 3L is stopped as the second reel, if the winning line where “Watermelon” is tempered is replaced with the winning line where “Watermelon” is stopped for the first reel, the reel 3 stops as the third reel. The left reel 3L is stopped in the same manner as the above. When “JAC” and “Watermelon” are aligned on the winning line and become a single bonus tempering state, “Watermelon” is drawn on the winning line for the third reel, and the single bonus is won. If “watermelon” is lined up on the winning line and becomes a watermelon tempering state, “watermelon” is also drawn on the winning line for the third reel, and the watermelon is awarded. On the other hand, even if “7” and “watermelon” are lined up on the winning line when the left reel 3L, which is the second reel, stops, the “watermelon” is not drawn on the winning line on the third reel, and the RT symbol is not lost. Let the design be derived.

  In addition, when the rotation of the reels 3L, 3C and / or 3R is automatically stopped, there is no limit on the number of frames to be drawn on any winning line except when only the left reel 3L is automatically stopped. The winning symbol combinations and RT symbols are not derived. When only the left reel 3L is automatically stopped, “watermelon” stops on the winning line for the reels 3C and 3R stopped by operating the stop buttons 12C and 12R as the first and second reels. ing. In this case, “7” in the 2nd to 4th positions of the left reel 3L is drawn onto the winning line where “Watermelon” is tempered, and the RT symbol is derived.

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

  The commands transmitted from the game control board 101 to the effect control board 102 include at least a winning status notification command and a game state command. The commands transmitted from the game control board 101 to the effect control board 102 include other commands, but since they are not directly related to the present invention, a detailed description thereof is omitted. The winning status notification command indicates the setting status of the winning flag in the RAM 112, and is transmitted when the start lever 11 is operated and an internal lottery is performed. The gaming state command indicates a gaming state applied in the next game, and is transmitted at the end of one game.

  The CPU 121 of the effect control board 102 performs various effects based on the commands sent from the CPU 111 of the game control board 101 as described above. In the slot machine 1 of this embodiment, when it is determined by the gaming state command that the gaming state is the challenge bonus, if it is determined that the single bonus is won by the winning status notification command, a predetermined winning notification is displayed on the liquid crystal. This is performed in the display 4. The RAM 122 is provided with an area (for one game) that stores the gaming state indicated by the gaming state command.

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

  FIG. 8 is a flowchart showing a game control process performed by the CPU 111 of the game control board 101 for each game. This process is also executed after the power is turned on and a predetermined boot process is performed, or immediately after the setting is changed by operating the setting switch 91. When the process of one game is started, first, an initial process including a process of clearing a predetermined area of the RAM 112 is performed (step S1).

  Next, the number of bets is set by operating one BET button 14 or MAXBET button 15 or by inserting medals from the medal insertion slot 13, and operating the start lever 11 to substantially change the game. BET processing for instructing start is performed (step S2). When the bet number is determined, a BET command is generated and transmitted to the effect control board 102. Here, when the gaming state is a regular bonus (including that provided during the big bonus), if the bet number is set to 1 (the bet number larger than this is not set), the start lever 11 is activated. Become. In other game states, the start lever 11 becomes effective after 3 is set as the bet number. Further, if the player has won a replay in the previous game, the same bet number (3 in this embodiment) as the previous game is automatically set by the replay game flag (the replay game flag is erased at this stage). The start lever 11 becomes effective as it is.

  When the number of bets is set by the BET process and the start lever 11 is operated, a random number for internal lottery is extracted, and winning to each combination determined according to the gaming state is allowed based on the extracted random number value A lottery process for determining whether or not to perform is performed (step S3). In the lottery process, a winning status notification command indicating the setting status of the winning flag in the RAM 112 is transmitted to the effect control board 102. Details of the lottery process will be described later.

  When the lottery process is completed, a reel rotation process is performed (step S4). In the reel rotation process, the reel motor is operated on the condition that a predetermined time (for example, 4.1 seconds) has elapsed from the start of rotation of the reels 3L, 3C, and 3R in the previous game. 3ML, 3MC, and 3MR are driven to start rotation of all the left, middle, and right reels 3L, 3C, and 3R. When predetermined conditions (detection of the reference position by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed) from the start of rotation of the reels 3L, 3C, 3R are satisfied, the stop buttons 12L, 12C, 12R Is enabled. Thereafter, when the stop buttons 12L, 12C, and 12R are operated by the player, the driving of the reel motors 3ML, 3MC, and 3MR is stopped according to the setting state of the winning flag, and the rotation of the reels 3L, 3C, and 3R is stopped. . When the rotation of the reels 3L, 3C, 3R is started and stopped, a reel rotation command and a reel stop command are transmitted to the effect control board 102, respectively. Details of the reel rotation process will be described later.

  When the driving of each of the reels 3L, 3C, 3R is stopped, in the display mode at the time of stopping, whether any of the above-mentioned role symbols is derived and displayed on the winning line according to the bet number set in the BET process in step S2 A winning determination process for determining whether or not is performed (step S5). If it is determined in this winning determination process that a winning combination has been won, various processes corresponding to the winnings generated on the game control board 101 are performed. Here, a winning information command indicating a winning determination result is sent to the effect control board 102. Details of the winning determination process will be described later.

  When the winning determination process ends, a payout process is performed (step S6). In the payout process, the credit is increased by the number of payouts set in the winning determination process. However, when the number of credits accumulated as data reaches 50, the hopper motor 82 is driven to pay out an excess number of medals from the medal payout slot 71. In addition, various processes that are not related to winning (for example, a process related to the end control of the big bonus and the deletion of a winning flag that does not carry over) are also performed. At the end of the payout process, that is, at the end of one game, a game state command indicating the game state of the next game is sent to the effect control board 102. Details of the payout process will be described later. Then, the process for one game ends, and the process for the next one game starts.

  Next, the lottery process in step S3 will be described in detail. FIG. 9 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S3. In the lottery process, it is determined whether or not the gaming state is the big bonus depending on whether or not the big bonus flag is set in the RAM 112 (step S101). If the gaming state is not the big bonus, the process proceeds to step S104 as it is.

  If the gaming state is a big bonus, it is determined whether or not the gaming state is a regular bonus depending on whether or not the regular bonus flag is set in the RAM 112 (step S102). If the game state is not in the regular bonus, it is the first game of the big bonus, or the game is a game when the regular bonus for one set in the big bonus has ended and the big bonus has not ended yet. A regular bonus medium flag is set to control the gaming state to a regular bonus (step S103). Then, the process proceeds to step S104. If the gaming state is a regular bonus, the process proceeds to step S104 as it is.

  In step S104, random number acquisition processing is performed, and by outputting a sampling command, the random number generated by the random number generation circuit 115 is extracted by the sampling circuit 116 and stored in the random number storage area for internal lottery in the RAM 112. The random numbers for the internal lottery may be used after being processed in a predetermined procedure by software instead of using the random numbers extracted from the random number generation circuit 115 as they are.

  Next, in correspondence with the current gaming state, the lottery target combination registered in the winning combination table according to gaming state in FIG. 5B is sequentially read (step S105). Next, the number of determination values stored in the address registered in the role-specific table corresponding to the gaming state and set value read for the lottery target is acquired (step S106). Then, the acquired number of determination values is added to the internal lottery random value stored in the determination area of the RAM 112, and the result of the addition is used as a new internal lottery random value (step S107). Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the value of the random number for internal lottery (step S108).

  If no overflow has occurred, it is determined whether there is a combination that has not yet been processed among the lottery targets in the gaming state (step S109). If there is something that has not yet been processed, the process returns to step S105, and the process continues with the next lottery target registered in the winning combination table by gaming state as the processing target. If there is nothing not to be processed, the process proceeds to step S113.

  If an overflow has occurred, it is determined whether the lottery target combination is a regular bonus, a big bonus challenge bonus, or a single bonus (step S110). If the lottery target is neither a regular bonus, a big bonus, a challenge bonus, or a single bonus, the process proceeds to step S112.

  If the bonus is a regular bonus, big bonus, challenge bonus or single bonus, whether the value of the special role temporary storage register is 0, that is, a regular bonus winning flag, a big bonus winning flag, or a challenge bonus from the previous game It is determined whether or not the winning flag is carried over (step S111). If the value of the special role temporary storage register is not 0, the process proceeds to step S113 as it is. If the value of the special role temporary storage register is 0, the process proceeds to step S112. In step S112, the winning flag of the lottery object combination is set in the winning flag storage register. Then, the process proceeds to step S113.

  In step S113, it is determined whether or not the game state of the current game is a challenge bonus depending on whether or not the challenge bonus flag is set in the RAM 112. If the gaming state is not a challenge bonus, the process proceeds to step S115 as it is. If it is a challenge bonus, a watermelon winning flag, a bell winning flag, and a cherry winning flag are set in the winning flag storage register. When the single bonus winning flag is set, the watermelon winning flag, the bell winning flag, the cherry winning flag, and the single bonus winning flag are set in the winning flag storage register (step S114). ). Then, the process proceeds to step S115.

  In step S115, the lower byte of the winning flag storage register, that is, a value corresponding to the setting status of the winning flag for the general combination is stored in the general combination temporary storage register. Next, it is determined whether or not the upper byte of the winning flag storage register is 0, that is, whether the regular bonus or the big bonus is not won in this game (step S116). If the upper byte of the winning flag storage register is not 0, the upper byte of the winning flag storage register, that is, a value corresponding to the setting state of the winning flag of the special role is stored in the special role temporary storage register (step S117). Then, the process proceeds to step S120.

  If the upper byte of the winning flag storage register is 0, whether the value of the special role temporary storage register is 0, that is, the regular bonus winning flag, the big bonus winning flag, or the challenge bonus winning flag is carried over from the previous game. It is determined whether it is not (step S118). If the value of the special role temporary storage register is not 0, the regular bonus winning flag, the big bonus winning flag, or the challenge bonus winning flag is set in the upper byte of the winning flag storing register according to the value (step S119). Then, the process proceeds to step S120. If the value of the special role temporary storage register is 0, the process proceeds to step S120 as it is.

  In step S120, the value stored in the special role temporary storage register is written in the accumulator of the CPU 111. Further, the value of the lower 4 bits of the accumulator is shifted to the upper 4 bits (step S121). Next, the value stored in the general combination temporary storage register is added to the value stored in the accumulator, and this is stored in the accumulator (step S122). Then, the value stored in the accumulator is stored in the index search register (step S123).

  Further, a winning status notification command is generated according to the setting status of the winning flag of each combination indicated by the winning flag storage register or the index search register, and is transmitted to the effect control board 102 (step S124). Then, the lottery process is terminated, and the process returns to the flowchart of FIG.

  Next, the reel rotation process in step S4 will be described in detail. FIG. 10 is a flowchart showing in detail the reel rotation process executed by the CPU 111 in step S4. In the reel rotation process, first, it is determined whether or not a wait time (for example, about 4.1 seconds) has elapsed since the reel rotation start time of the previous game (step S201). If the wait time has not elapsed, Wait until the wait time has elapsed. If the wait time has elapsed, timing of the wait time is newly started (step S202). Also, the timing of the reel stop timer is newly started (step S203).

  Next, a work initialization code at the start of reel motor rotation is set in the register, and reel rotation is started (step S204). Then, with reference to the table index, the table creation data is identified, and based on the identified table creation data, a stop control table corresponding to the game state of the game, the internal winning situation, and the other reels stop situation is created. Then, a reel is created for each rotating reel (step S205), and a work initialization code at the completion of stop preparation is set in the register (step S206). Thereby, the operation of the stop buttons 12L, 12C, and 12R becomes valid.

  Next, it is determined whether or not the reel stop timer timed in step S203 has timed a predetermined automatic stop time (for example, 30 seconds) (step S207). If the automatic stop time is counted, among the reels that are still rotating, the game state of the game, the internal winning situation, the other reels in the order of the left reel 3L, the middle reel 3C, and the right reel 3R An automatic stop table that defines the number of stop steps of the reel corresponding to the stop state is created (step S208). After that, it waits until the rotation of the reel (3L, 3C, 3R) corresponding to the created automatic stop table stops (step S209).

  When the rotation of the reel (3L, 3C, 3R) corresponding to the created automatic stop table stops, it is determined whether all of the reels 3L, 3C, 3R have stopped (step S210). If the rotation of the reels 3L, 3C, 3R is not stopped, the process returns to step S208. If the rotation of all the reels 3L, 3C, 3R is stopped, the reel rotation process is terminated and the process returns to the flowchart of FIG.

  If the reel stop timer has not counted the automatic stop time, it is determined whether any one of the stop buttons 12L, 12C, and 12R has been detected (step S211). If no stop button operation is detected, it is determined whether a reel rotation error (an error determined when the reel reference position is not detected by the reel sensors 3SL, 3SC, 3SR for a certain period or more) has occurred. (Step S212). If no reel rotation error has occurred, the process returns to step S207.

  If it is determined in step S212 that a reel rotation error has occurred, an error code indicating a reel rotation error is set in the register (step S213), and the process proceeds to a predetermined error process (step S214). Along with this, the rotation of the reels 3L, 3C, 3R is also temporarily stopped. If the error is released, the process returns to step S204 again, and the rotation of the reels 3L, 3C, 3R is resumed.

  If the operation of the stop button 12L, 12C, or 12R is detected in step S211, the reel motor (3ML, 3MC, or 3MR) corresponding to the operated stop button from the reel reference position at that time is detected. The number of steps (the number of steps at the stop operation position) is acquired and set to the work corresponding to the stop reel (step S215). Then, it waits until the rotation of the reel (any one of 3L, 3C, 3R) corresponding to the operated stop button stops (step S216).

  When the rotation of the reel (3L, 3C, or 3R) corresponding to the operated stop button stops, it is determined whether or not all of the reels 3L, 3C, and 3R have stopped (step S217). If the rotation of the reels 3L, 3C, 3R is not stopped, the process returns to step S205. If the rotation of all the reels 3L, 3C, 3R is stopped, the reel rotation process is terminated and the process returns to the flowchart of FIG.

  Next, the winning determination process in step S5 will be described in detail. FIG. 11 is a flowchart showing in detail the winning determination process executed by the CPU 111 in step S5. In the winning determination process, a winning flag corresponding to the role symbol derived on any winning line of the display result of the variable display device 2 is set in the winning flag storage register of the RAM 112. For example, when the regular bonus symbols are arranged on the winning line of the variable display device 2, the value of the most significant bit of the upper byte of the winning flag storage register is 1 and the values of the other bits are 0 (step) S301).

  Next, the value of each bit in the winning flag storage register of the RAM 112 is inverted. For example, when only the regular bonus winning flag is set, the value of the most significant bit of the upper byte of the winning flag storage register is 0 and the value of the other bits is 1. Then, the data of the winning flag storage register and the data of the winning flag storage register are logically ORed for each bit (step S302). Then, it is determined whether or not the result of the logical sum operation in step S302 is 0 (step S303). If the result of the logical sum operation in step S302 is not 0, it means that the winning combination for which the winning flag has not been set has been won. In this case, the routine proceeds to predetermined error processing.

  If the result of the logical sum operation in step S302 is 0, it is determined whether or not a replay winning is made based on whether or not a replay winning flag is set in the winning flag storage register (step S304). If a replay prize has been won, a replay game flag is set in the RAM 112 (step S305). The replay game in-progress flag is deleted when the bet number is automatically set in the next game. Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the replay winning is not made, it is determined whether or not the regular bonus is won depending on whether or not the regular bonus winning flag is set in the winning flag storage register (step S306). If the regular bonus has been won, the regular bonus flag is set in the RAM 112, the special role temporary storage register value is initialized to 0, and the RT1 and RT2 counter values in the RAM 112 are cleared to 0 (step S307). . Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the regular bonus has not been won, it is determined whether or not the big bonus has been won depending on whether or not the big bonus winning flag is set in the winning flag storage register (step S308). If the big bonus has been won, the big bonus medium flag is set in the RAM 112, the special role temporary storage register value is initialized to 0, and the RT1 and RT2 counter values in the RAM 112 are cleared to 0 (step S309). . Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the big bonus has not been won, it is determined whether or not the challenge bonus has been won based on whether or not a challenge bonus winning flag is set in the winning flag storage register (step S310). If the challenge bonus has been won, the challenge bonus flag is set in the RAM 112, the special role temporary storage register value is initialized to 0, and the RT1 and RT2 counter values in the RAM 112 are cleared to 0 (step S311). . Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the challenge bonus is not won, it is determined whether or not a single bonus is won in the current game, depending on whether or not a single bonus winning flag is set in the RAM 112 (step S312). If no single bonus is won in this game, it is impossible to win a single bonus or derive an RT symbol, so the winning determination process is terminated and the process returns to the flowchart of FIG.

  If the single bonus is won in this game, the challenge bonus flag is erased from the RAM 112, and the value of the special role temporary storage register is initialized to 0 (step S313). Next, it is determined whether or not a single bonus is won depending on whether or not a single bonus winning flag is set in the winning flag storage register (step S314). Here, if a single bonus is won in the normal gaming state, RT1 or RT2, a single bonus will always be won. If a single bonus has been won, a single bonus medium flag is set in the RAM 112 (step S315). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If no single bonus is won in step S314, the game state of the current game is a challenge bonus, and it is determined whether or not an RT symbol is derived on the variable display device 2 (step S316). If the RT symbol is not derived, the winning determination process is terminated as it is, and the process returns to the flowchart of FIG. If the RT symbol is derived, 101 is set as the initial value of the RT1 counter. The reason why the initial value set here is 101 instead of 100 is that the value of the RT1 counter is decremented by 1 in step S418 (described later) until the processing of this game ends (step S317). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  Next, the payout process in step S6 will be described in detail. FIG. 12 is a flowchart showing in detail the payout process executed by the CPU 111 in step S6. In the payout process, it is determined whether or not there is a small prize winning accompanied by a medal payout depending on whether or not any of the watermelon, bell, and cherry winning flags is set in the RAM 112 (step S401). If the small role is not won, the process proceeds to step S403 as it is.

  If the small role winning is achieved, the number of medals is sequentially paid out by controlling the hopper 80. However, the number of credits is increased instead of paying out medals until the number of credits accumulated as data reaches 50 (step S402). Then, the process proceeds to step S403.

  Here, it is determined in step S401 that the small role is not won, or the medal payout in step S402 is ended, so that it is determined that one game is ended. That is, when the small role is won, it is determined that the game is over when the payout of the medal is completed. This is the same as determining that the game is over when the result is derived. The operation of the checkout button 16 is effective here, but the operations of the single BET button 14 and the MAXBET button 15 are not yet effective.

  In step S403, it is determined whether or not the current gaming state is a regular bonus (including those provided during the big bonus) depending on whether or not the regular bonus flag is set in the RAM 112. If the current gaming state is not a regular bonus, the process proceeds to step S407. If the current gaming state is a regular bonus, the number of games and winnings in the regular bonus are counted using the counter of the RAM 112 (step S404).

  As a result of the count, it is determined whether or not a regular bonus end condition has been met (step S405). If the regular bonus end condition is satisfied, the regular bonus medium flag in the RAM 112 is deleted. Also, a counter value for counting the number of games and the number of winnings in the regular bonus is initialized (step S406). Then, the process proceeds to step S407. If the regular bonus end condition is not satisfied, the process proceeds to step S407.

  In step S407, it is determined whether or not the current gaming state is a big bonus depending on whether or not the big bonus flag is set in the RAM 112. If the current gaming state is a big bonus, the number of payout medals in the big bonus is counted using the counter of the RAM 112 (step S408). The number of payout medals counted here exceeds 345, and it is determined whether or not the big bonus end condition is satisfied (step S409). If the big bonus end condition is not satisfied, the process proceeds to step S421.

  If the big bonus end condition is satisfied, the big bonus medium flag in the RAM 112 is deleted. If the regular bonus medium flag is set, it is also deleted. Also, a counter value for counting the number of payout medals in the big bonus is initialized. Also, a counter value for counting the number of games and the number of winnings in the regular bonus is initialized (step S410). Then, the process proceeds to step S421.

  If the current gaming state is not a big bonus in step S407, it is determined whether or not the current gaming state is a challenge bonus depending on whether or not the challenge bonus flag is set in the RAM 112 (step S411). If the current gaming state is a challenge bonus, the number of payout medals in the challenge bonus is counted using the counter of the RAM 112 (step S412). The number of payout medals counted here exceeds 238, and it is determined whether or not the challenge bonus end condition is satisfied (step S413). If the end condition for the challenge bonus is not satisfied, the process proceeds to step S421 as it is.

  If the challenge bonus end condition is satisfied, the challenge bonus flag in the RAM 112 is erased. Also, a counter value for counting the number of medals paid out in the challenge bonus is initialized. Further, the challenge bonus ends on condition of the number of paid-out medals, and 100 is set as the initial value of the RT2 counter in the RAM 122 in order to control the gaming state to RT2 from the next game (step S414). Then, the process proceeds to step S421.

  If the current gaming state is not a challenge bonus in step S411, it is determined whether or not the current gaming state is a single bonus depending on whether or not the single bonus flag is set in the RAM 122 (step S415). If the current gaming state is a single bonus, the single bonus medium flag in the RAM 112 is erased (step S416). Then, the process proceeds to step S421.

  If the current gaming state is not a single bonus, whether or not the current gaming state is RT1 (or whether it will be RT1 from the next game) depending on whether the value of the RT1 counter in the RAM 112 is 1 or more. ) Is determined (step S417). If the current gaming state is RT1, the value of the RT1 counter is decremented by 1 (step S418). Then, the process proceeds to step S421.

  If the current gaming state is not also RT1, whether or not the current gaming state is RT2 is determined based on whether the value of the RT2 counter in the RAM 112 is 1 or more (step S419). If the current gaming state is RT2, the value of the RT2 counter is decremented by 1 (step S420). Then, the process proceeds to step S421. If the current gaming state is not also RT2, the process proceeds to step S421 as it is.

  In step S421, based on the state of the big bonus medium flag, the regular bonus medium flag, and the challenge bonus medium flag in the RAM 112, the gaming state applied in the next game (here, the normal gaming state, the challenge bonus, or the big bonus) A game state command indicating a regular bonus that is not in bonus is generated and transmitted to the effect control board 102.

  Further, the winning flag set in the winning flag storage register and the winning flag set in the winning flag storage register are all erased. Even if the regular bonus winning flag, big bonus winning flag or challenge bonus winning flag is set in this game and the regular bonus, big bonus or challenge bonus is not won, the value of the special role temporary storage register will be Since it is not cleared, the regular bonus winning flag, the big bonus winning flag or the challenge bonus winning flag is carried over to the next game. Even if it is a special role, the single bonus winning flag is erased in step S416 and is not carried over to the next game. On the other hand, since the value of the general combination temporary storage register is always rewritten according to the result of the internal lottery of the next game, the winning flag of the general combination is not carried over to the next game (step S422). Then, the payout process is terminated, and the process returns to the flowchart of FIG. Here, when returning to the flowchart of FIG. 8, the process in the current one game ends.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 performs the transition of the game state among the normal game state, RT1, RT2, single bonus, regular bonus, big bonus, challenge bonus. A command is transmitted to the effect control board 102 in accordance with the progress status of. On the other hand, the CPU 121 of the effect control board 102 performs an original effect based on the command received from the game control board 101. Hereinafter, the process of the effect performed by the control on the effect control board 102 side will be described.

  FIG. 13 is a flowchart showing processing executed by the CPU 121 of the effect control board 102. On the side of the effect control board 102, it is determined whether or not the command sent from the game control board 101 has been received (step S501). When any command is received from the game control board 101, the type of the received command is determined (step S502).

  If the received command type is the winning status notification command transmitted in step S124, the gaming state received at the end of the previous game and stored in the RAM 122 (that is, the gaming state of the current game) is a challenge. It is determined whether the bonus is indicated (step S503). If the game state of the current game does not indicate that it is in the challenge bonus, the process returns to step S501 as it is.

  If the game state of the current game indicates that it is in the challenge bonus, it is determined whether or not the received winning status notification command indicates that the single bonus has been won (step S504). If the winning of the single bonus is indicated, a predetermined winning notification is given on the liquid crystal display 4 (step S505). Then, the process returns to step S501. If the winning of the single bonus is not indicated, the process returns to step S501 as it is.

  If the received command type is the gaming state command transmitted in step S421, the gaming state indicated by the received gaming state command (that is, the gaming state applied in the next game) is stored in a predetermined area of the RAM 122. (Step S506). Then, the process returns to step S501.

  If the received command type is another command, processing corresponding to each command type is executed (step S507). Since the processing executed when other types of commands are received is not related to the present invention, detailed description thereof is omitted. Thereafter, the process returns to step S501.

  As described above, in the slot machine 1 according to this embodiment, a single bonus may be won regardless of whether there is a game state in the normal game state, RT1 or RT2, or if there is a game state in the challenge bonus. is there. Here, when there is a game state in the challenge bonus, the number of drawn frames for the left reel 3L is only one frame at a maximum, and a single bonus that is not missed in the normal game state, RT1 or RT2, may be missed. When a single bonus is missed in the challenge bonus, a normal gaming state, an RT symbol that is not derived in RT1 or RT2, may be derived, so that the gaming state is controlled by RT1 only for the next 100 games. .

  Thus, the gaming state is controlled to RT1 by limiting the chance that the gaming state is controlled to RT1 based on the derivation of the RT symbol only when the single bonus is won and the gaming state is the challenge bonus. There will be a sharpening of opportunities. On the other hand, the RT symbol for controlling the gaming state to RT1 is not determined as a winning combination display mode, and is not an object of internal lottery. For this reason, since the RT symbol is derived only when the challenge bonus is present, the other winning combinations are not derived. Also, an opportunity to win a single bonus, which is a premise for deriving an RT symbol, can be given not only when the gaming state is the challenge bonus but also when it is in the normal gaming state, RT1 or RT2.

  Further, when the single bonus is won in the challenge bonus, the challenge bonus is terminated after the game ends, but the challenge bonus is also terminated when the number of payout medals exceeds 238. In this case, the gaming state is controlled to RT2 having a lower replay winning probability (but higher than the normal gaming state) than RT1 when the RT symbol is derived based on the winning of the single bonus. Even if the single bonus is won, if the prize is won as it is, the challenge bonus is ended, and the game is controlled to the normal game state through the single bonus of one game. As described above, the player pays attention also to the end condition of the challenge bonus, so that the interest of the game can be improved.

  In addition, when a single bonus is won in the challenge bonus, the challenge bonus, which is a game state advantageous to the player, ends, but here, the game state is advantageous to the player different from the challenge bonus. An opportunity to let RT1 control is given. The single bonus ends when the number of paid out medals exceeds 238 even if the challenge bonus is not won, so if you win a watermelon with a large number of paid out medals each time, the game will end with fewer games. As a result, the chance of winning the single bonus and allowing RT1 to control the gaming state is reduced.

  On the other hand, if the single bonus is not won in the challenge bonus, priority is given to the derivation of a watermelon with a large number of paid-out medals, but depending on the operation procedure of the stop buttons 12L, 12C, 12R, only 5 paid-out medals are obtained. You can also win the bell of By winning the bell, it is possible to increase the chances of winning the single bonus by increasing the number of challenge bonus games while maintaining a positive increase / decrease in medals. Thereby, the strategy of the game in the single bonus is further increased, and the interest of the game can be further improved.

  By the way, even if a single bonus is won in the challenge bonus, the RT symbol cannot always be derived, and the RT symbol cannot be derived unless the stop buttons 12L, 12C, and 12R are operated in a certain procedure. . That is, since it is necessary for the player to intervene in the operation of the stop buttons 12L, 12C, 12R with the intention of deriving the RT symbol, the interest of the game can be further improved.

  However, in the slot machine 1 according to this embodiment, if there is a reel that has not stopped rotating even after 30 seconds from the start of rotation of the reels 3L, 3C, 3R, such a reel is automatically stopped. The Rukoto. If the single bonus is won in the challenge bonus, the RT symbol can be derived simply by automatically stopping. In this way, as long as the player has an intention to derive the RT symbol in the challenge bonus, the RT symbol can be derived by a simple intervention method in which the aggressive stop operation is not performed. Regardless of the skill level, RT1 can control the gaming state.

  Furthermore, in the slot machine 1 according to this embodiment, the symbol combination of the single bonus is “JAC-watermelon-watermelon”, the symbol combination of the watermelon having the largest number of payout medals is “watermelon-watermelon-watermelon”, and the symbol of the RT symbol. The combination is “7-watermelon-watermelon”. Here, in order to derive the RT symbol without depending on the automatic stop, the left reel 3L needs to be the third reel. However, if the left reel 3L is the third reel, any symbol is derived. Even so, the control for the right and middle reels 3C and 3R is performed in the same manner.

  Thus, until the left reel 3L is stopped as the third reel, the RT symbol can be derived only by looking at the stop control of the reels 3C and 3R, that is, it is not known whether the single bonus is won or not. The expectation of the person is not lost. However, when the single bonus is won during the challenge bonus, the fact is notified so that the player can expect that the RT symbol will be derived and the gaming state will be controlled to RT, and the game will be more interesting. Can be improved.

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

  In the above embodiment, the RT symbol is the display mode of the loss when the symbol combination “7-watermelon-watermelon” is aligned on any winning line, but is not limited thereto. In the normal gaming state, the winning combination is a display mode of a small role with a winning probability of 0 (or very close to 0), and is awarded only when a single bonus is won in the challenge bonus and the single bonus cannot be won. It may be a display mode. When the RT symbol is displayed in the small role display mode, when winning a small role that also serves as the RT symbol, the same number of medals as other small roles with the largest number of payout medals are paid out, or the RT symbol is also used. A single bonus can be won without winning a small role, and a medal equivalent to the expected value of the number of medals obtained in the single bonus of the next game can be paid out.

  In addition, the RT symbol may not be a display mode of a symbol combination which may be derived on any winning line, but may be a display mode of a symbol combination derived on a specific winning line. A display mode in which a single bonus symbol combination is derived on a specific winning line (in a normal gaming state, in RT1 and RT2, a display mode in which a single bonus symbol combination is not derived on the specific winning line) may be adopted. .

  In addition, there are two types of symbol combinations for single bonus (for example, “JAC-watermelon-watermelon” and “BAR-watermelon-watermelon”), and one of them (for example, “BAR-watermelon-watermelon”) also serves as an RT symbol. It may be a thing. In this example, when the single bonus winning flag is set, the symbol combination “JAC-watermelon-watermelon” is given priority over the symbol combination “BAR-watermelon-watermelon”. In the state, the number of frames drawn in the left reel 3L is 4, so the symbol combination of “BAR-watermelon-watermelon” that also serves as the RT symbol cannot be derived, but the challenge bonus has the number of frames drawn in, so the stop buttons 12L, 12C Depending on the operation procedure of 12R, it becomes possible to derive a symbol combination of “BAR-watermelon-watermelon” which also serves as an RT symbol.

  Note that the single bonus that does not double the RT symbol of “JAC-watermelon watermelon” and the single bonus that doubles the RT symbol of “BAR-watermelon-watermelon” are display results derived based on separate winning flags. When the single bonus is won, only the former winning flag may be set in the normal gaming state, and both the former and latter winning flags may be set in the challenge bonus. Alternatively, a single bonus winning flag is set as a single bonus, and when a single bonus is won, a single bonus winning flag is set for only one type in both the normal gaming state and the challenge bonus. The display result that can be derived based on the bonus winning flag may be only the display result of the former, and the display result that can be derived based on the single bonus winning flag of the challenge bonus may be the display result of both the former and the latter.

  In the embodiment described above, when the challenge bonus is terminated by winning the single bonus, the gaming state is controlled to RT1 only for the next 100 games on condition that the RT symbol is derived, and the challenge bonus is determined by the number of medals paid out. When the game is ended, the gaming state is controlled to RT2 having a lower replay win probability than RT1 only for the next 100 games. On the other hand, for example, when the challenge bonus is terminated by the number of paid-out medals, the gaming state may be controlled to RT1 only for the next 50 games. Or it is good also as what controls to a normal game state as it is.

  In the above embodiment, the gaming state controlled based on the RT symbol that can be derived only when the single bonus is won in the challenge bonus, the RT (the winning probability of replay is higher than the normal gaming state) In particular, RT1), an AT (Assist Time) for notifying the operating procedure of the stop buttons 12L, 12C, 12R for winning the type of the selected small combination and winning the selected small combination, or RT And AR combined with AT.

  In the above embodiment, when the rotation of the reels 3L, 3C, and 3R is automatically stopped according to the elapsed time from the start of the rotation of the reels 3L, 3C, and 3R, the number of symbols to be drawn is not limited. A limit of the number of frames that can be drawn up to a maximum of 4 frames (a maximum of 1 frame for the left reel 3L in the challenge bonus) may be provided. If the number of frames to be drawn in the left reel 3L is a maximum of 4, it is possible to control so as not to derive the RT symbol.

  In the above embodiment, when the single bonus is won in the challenge bonus, among the three reels 3L, 3C, 3R, the middle and right reels 3C, 3R are stopped by operating the stop buttons 12C, 12R, and left If the reel 3L is automatically stopped, the RT symbol is always derived. However, even in such a case, it is possible not to derive RT symbols at a predetermined rate. Further, the number of frames drawn on the left reel 3L is limited to a predetermined number of frames (for example, 4 frames), and “7” is placed on the winning line where the “watermelon” is tempered with the number of frames drawn when the automatic stop condition is satisfied. The RT symbol can be derived only when it can be withdrawn. In this case, when the single bonus is won in the challenge bonus, the RT symbol may not be derived even if the left reel 3L is automatically stopped. It is necessary to perform an appropriate stop operation, and the technical intervention for deriving the RT symbol is not impaired.

  In the above embodiment, the reel whose maximum stop delay time is reduced to 75 milliseconds in the challenge bonus, that is, the reel whose number of drawn frames is limited to one frame is the left reel 3L. It may be 3C or the right reel 3R. For example, when the maximum stop delay time of the right reel 3R is shortened, the symbol arrangement of the left reel 3L and the right reel 3R shown in FIG. 2 may be interchanged. In this case, when the single bonus is won in the game state of the challenge bonus, the RT symbol can be derived even by a forward push operation (performing a stop operation in order of left → middle → right).

  In the above embodiment, in the game state of the challenge bonus, the watermelon winning flag, the bell winning flag, and the cherry winning flag are set in the winning flag storing register regardless of the single bonus lottery result (single bonus winning flag). If so, the single bonus winning flag is also set). On the other hand, in the challenge bonus, a single bonus lottery is performed with a predetermined winning probability, and a watermelon, bell and cherry lottery is performed with a winning probability of 100%. The winning flag may be set in the winning flag storage register.

  Alternatively, in addition to a single bonus, watermelon, bell, and cherry are also lottery with a predetermined winning probability that is not 100%, and the winning flag of the winning combination determined based on the lottery result is set in the winning flag storage register. However, the watermelon winning flag, the bell winning flag, and the cherry winning flag may be overwritten and set in the winning flag storage register thereafter. In addition, in the challenge bonus, the watermelon, bell and cherry are not drawn other than the single bonus, and no winning flag other than the single bonus winning flag is set, but depending on the operation procedure of the stop buttons 12L, 12C and 12R A stop control table that wins in priority order of watermelon, bell, and cherry (in addition, if a single bonus is won, a win is given in preference to these single bonuses) is generated, and reels 3L, 3C are generated according to this stop control table 3R stop control may be performed.

  In the above embodiment, the winning notification is performed only when the single bonus is won in the challenge bonus. In this case, the middle and right reels 3C, 3R are stopped at any timing with the stop buttons 12C, 12R. If the left reel 3L is automatically stopped while operating to stop the RT symbol, the RT symbol is always derived. On the other hand, in the challenge bonus, even when the single bonus is not won, a winning notification similar to that at the time of winning the single bonus may be performed at a predetermined rate.

  In this case, when the winning notification is made in the challenge bonus, the player is allowed to derive the RT symbol and cause the gaming state to be controlled by RT1, regardless of whether or not the single bonus is actually won. It will be possible to expect and further improve the fun of the game. Here, in order to derive the RT symbol, it is necessary to stop the left reel 3L as the third reel, but the middle and right reels 3C and 3R, which are the first and second reels, have a single symbol. Regardless of whether or not the bonus is won, “Watermelon” will be tempered. Whether or not the single bonus has been won is actually known when the rotation of the left reel 3L, which is the third reel, has stopped. For this reason, the player's expectation heightened by winning notification is not lost before the first and second reels are stopped.

  In such a case, when the winning notification is made without winning the single bonus, if the left reel 3L is automatically stopped, the small part that can be won with the challenge bonus will be missed. Become. In this way, there is a risk of missing a small role if the player automatically stops the reel without actively stopping it, so the player actively stops the operation for deriving the RT symbol. It can be directed to do so and does not impair the technical intervention for the derivation of RT symbols.

  In the above embodiment, in the game state of the challenge bonus, it was assumed that only the single bonus lottery was performed, but if a replay lottery is performed and this is won, the replay winning flag is set. Also good. In this case, when the single bonus or the replay is won in the gaming state of the challenge bonus, the winning notification can be made on the liquid crystal display 4.

  In the embodiment described above, when determining an illegal winning, the data of each bit of the winning flag storage register is logically inverted, and the logical product operation is performed on the data of each bit of the winning flag storage register. On the other hand, the data of each bit of the winning flag storage register may be logically inverted, and this and the data of each bit of the winning flag storage register may be ORed. In this case, if the calculation result is 1, there is no illegal prize, and if it is 0, an illegal prize has occurred. Note that these operations can be appropriately changed depending on whether the bit indicating winning or winning is set to 0 or 1 or using positive logic or negative logic for the operation.

  In the above embodiment, the number of determination values for the lottery target determined according to the gaming state is sequentially added to the random number for internal lottery, and is read as the lottery target at the time when an overflow occurs as a result of the addition. He was supposed to win the role that had been put out. On the other hand, the number of determination values may be sequentially subtracted from the internal lottery random value, and the result of the subtraction may be used as a new internal lottery random value. When the number of determination values is subtracted from the random number value for internal lottery, it can be determined whether or not an overflow has occurred in the subtraction result (here, the subtraction result becomes negative).

  In the above embodiment, the internal lottery sequentially adds the number of judgment values for each combination according to the gaming state to the acquired random number for internal lottery, and the combination is won when the addition result overflows. It was supposed to be judged. On the other hand, a winning determination table in which a determination value for determining each combination as winning is determined for each game according to the number of determination values for each combination in accordance with the gaming state, and the internal random number for internal lottery acquired It is good also as what performs an internal lottery by comparing this value with the determination value of each combination.

  In the above embodiment, in a game in which the gaming state is the big bonus and the big bonus medium flag is set in the RAM 112, it is determined whether or not the regular bonus medium flag is set in the RAM 112 when the start lever 11 is operated. If the regular bonus medium flag is not set, this is set to control the regular bonus. In this way, the same processing may be performed when the regular bonus is controlled for the first time after winning the big bonus, or when the regular bonus is completed and the regular bonus is controlled again when the big bonus has not yet ended. I was supposed to.

  On the other hand, when the big bonus is won, a regular bonus medium flag is set in the RAM 112 together with the big bonus medium flag, and when the regular bonus end condition is established in the big bonus, the regular bonus medium flag is erased. Here, when the regular bonus medium flag is deleted, if it is determined that the big bonus end condition is not satisfied and the big bonus medium flag is set in the RAM 112, the regular bonus medium is again set. The flag may be set in the RAM 112 and controlled to a new regular bonus as it is. In this case, when the big bonus is controlled by winning the big bonus, it can be controlled to the regular bonus at the same time, and when the regular bonus for one time is finished and the big bonus is not finished yet, Will be able to return to regular bonus.

  In addition, the big bonus game state is that a small bonus game is provided by winning a big bonus, and a JACIN (for example, “BELL-JAC-JAC” is used in the small bonus game based on JACIN winning in the small bonus game. It is also possible to provide a regular bonus in a big bonus game state by winning a prize. If the regular bonus for one set is completed during the big bonus and the number of payout medals has not yet exceeded 345, it can be controlled again as a small role game.

  In the above embodiment, when some of the three reels 3L, 3C, 3R are already stopped, the internal winning state for each gaming state and the stop position of the stopped reel are unique. A stop control table that is determined in a specific manner is selected, and reel stop control is performed in accordance with the selected stop control table. Here, instead of the stop position of the stopped reel, the position when the stop buttons 12L, 12C, and 12R are operated to stop the reel (that is, the number of steps of the reel) may be applied. Good. Also in this case, similarly to the selection of the stop control table in the above embodiment, it is possible to obtain an effect that the control for stopping the reel does not become complicated.

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

  In the control method, when the operation of the stop button 12L, 12C, 12R is detected, the corresponding reels 3L, 3C, 3R are 190 milliseconds from the currently displayed symbol (the left reel 3L during the challenge bonus). Within the range of the maximum stop delay time of 75 ms (with a total of 5 frames including the displayed symbols and pull-in (2 frames for the left reel 3L during the challenge bonus))) Then, it is determined whether or not there is a winning symbol for which the winning flag is set. If there is a symbol with a winning flag set (determined from the symbol of the role that is given priority for derivation in duplicate wins), select the symbol for winning the winning combination and select the winning line (already stopped) When there is a reel, the winning display mode can be derived along with the symbols on the stopped reel. Otherwise, a symbol for not winning any combination is selected and derived. That is, even when the stop of the reels 3L, 3C, 3R is controlled by this control method, it can be derived by stopping the symbols within the range of the maximum stop delay time after the operation of the stop buttons 12L, 12C, 12R is detected. The display mode corresponding to the setting status of the winning flag is derived as the display result of the variable display device 2.

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

  In the above-described embodiment, the slot machine to which medals are applied as a game medium used for setting the number of bets and giving game value associated with winning is described as an example. However, the slot machine embodying the present invention may be a slot machine (so-called parrot) to which a game ball used in a pachinko gaming machine is applied as a game medium. When game balls are used as game media, for example, one medal can correspond to five game balls, and when three bets are set in the above embodiment, 15 game balls are used. This is equivalent to setting the number of bets using.
