The credit selection sensor 58 is a sensor for detecting that the credit selection button 20 has been operated. The payout medal detection sensor 59 detects medals paid out from the medal payout device 63, and the number of medals paid out is counted based on this detection information.

The setting device 60 is for switching the setting of the slot machine 1 based on the setting change operation. By this setting device 60, for example, the winning probability (internal winning probability) of various winnings in the internal lottery for each game is set to any of a plurality of settings (for example, settings 1 to 6).
The reset sensor 61 is, for example, a sensor for detecting that the key inserted into the keyhole 23 has been rotated in reverse to when the front frame 2 is opened, and resetting the slot machine 1 based on this detection. . Note that the game control device 50 cancels the error state of the slot machine 1 based on the detection signal from the reset sensor 61, for example. The front frame opening sensor 62 is a sensor for detecting the open state of the front frame 2.

In addition, the I / F 50d receives the control signal input from the CPU 50a via an output port and a driver (not shown), an effect control device 70, a game status indicator 19, a bet amount indicator 17, a credit amount indicator 11, and a payout. Number display 12, acquired number display 13, medal payout device 63, left reel motor 64a, middle reel motor 64b, right reel motor 64c, external output terminal (management provided separately from slot machine 1) Output to the terminal 65 connected to the device or the like, or the stop button LED 66 or the like. Thereby, the game control device 50 can control various components.
The control signal output to the external output terminal 65 includes, for example, a signal indicating the number of bets output when the start lever 21 is operated (game medal insertion signal), and a paid-out medal output when a medal is paid out. A signal indicating the number (game medal payout signal), a signal indicating that the big bonus state is being performed (BB signal), a signal indicating that the regular bonus state is being performed (RB signal), and indicating that the replay time is being performed A signal (RT signal), a signal (security signal) output when the front frame 2 is opened or a setting is changed.

  As described above, the game control device 50 is electrically connected to each component via the I / F 50d. In the game control device 50, for example, the CPU 50a updates a random number (for example, +1) every predetermined cycle time, performs a control to sample the random number at that time at the detection timing by the start lever sensor 52, and stores the sampled random number internally. An internal lottery is performed as a random number for lottery.

Further, the game control device 50 refers to the corresponding stop table based on the internal lottery result and the stop operation timing of the reel stop buttons 24a, 24b, 24c, and controls the operation of the reel motors 64a, 64b, 64c. By doing so, the reels 6a, 6b, 6c are stopped so that a predetermined symbol is stopped and displayed in the symbol display window 5.
For example, when a symbol constituting the symbol combination mode corresponding to the internal winning prize is stopped before reaching the valid line, the timing of stopping the reels 6a, 6b, 6c is delayed and the symbol is stopped. So as to stop and display on the active line.
Further, for example, when a stop operation is performed at a timing when a symbol combination mode corresponding to a winning that is not won internally is formed on the effective line, the timing for stopping the reels 6a, 6b, 6c is delayed to enable the effective line. A so-called kicking stop control is performed so that the symbols constituting the symbol combination aspect that can be formed above pass the effective line.
In the pull-in stop control and kick-off stop control by the game control device 50, the range in which the stop timing can be changed is within a predetermined number of symbols (for example, within 4 frames) from the position where the stop operation is performed.

On the other hand, the effect control device 70 includes a CPU 70a, a ROM 70b, a RAM 70c, an I / F 70d, and the like. The effect control device 70 controls the effect display in the image display device 3, the operation of the effect device 72, and the effect by the light emitting device 71 and the speaker 4 based on the information about the game output from the game control device 50. Take control.
Here, the information related to the game is bet number information output at the time when the start lever 21 is operated and the game is started (for example, a pulse number corresponding to the bet number is output, and the bet number and the game number are transmitted). Information), internal winning information indicating the lottery result by internal lottery, and game state information indicating the current gaming state (normal gaming state, BB state, RB state, RT state, etc.).

  The I / F 70d outputs various signals output from the game control device 50 to the CPU 70a via a low-pass filter and a buffer gate (not shown). The I / F 70d receives control signals input from the CPU 70a through an output port and a driver (not shown), the image display device 3, the speaker 4, the light emitting device (lamp, LED) 71, and the rendering device (motor, sensor). 72. As a result, various devices can be controlled by the effect control device 70.

Specifically, the effect control device 70 causes the image display device 3 to display a small role winning notice display, a special winning notice display, an effect display (thing completed in one game or over a plurality of games), and the like. (Display control means).
Further, the effect control device 70 controls the effect device 72 to operate the effect member 72a. In addition, the effect control device 70 performs decoration by light emission from the light emitting device 71 and an effect by sound from the speaker 4.

  The communication mode between the game control device 50 and the effect control device 70 described above is such that a control signal is transmitted only in one direction from the game control device 50 to the effect control device 70, and the game control device 50 is illegal. This prevents the input of various signals.

  When a game is played in the slot machine 1, first, a medal is inserted from the medal insertion slot 15, or the bet number is input by operating the max bet button 16 or the 1 bet button (betting input). When a bet is input, an active line is set according to the number of bets, and the operation of the start lever 21 is enabled, that is, the game can be started. Then, when the start lever 21 is operated, an internal lottery process is performed in the game control device 50, and winning / non-winning of the winning is determined, and the reel 6 starts to change.

After a predetermined time has elapsed, the reels 6a, 6b, 6c are stopped from rotating based on the operation of the reel stop buttons 24a, 24b, 24c, and a predetermined symbol is displayed in the symbol display window 5. When the symbol combination mode corresponding to the internal winning winning is formed on the active line, the winning is established, and the medal corresponding to the winning is paid out.
The game of one segment is completed as described above, and thereafter, the game is advanced by repeating this operation.

FIG. 3 is an arrangement diagram of symbols formed on the outer peripheral surface of the reel 6 included in the slot machine 1.
As shown in FIG. 3, on the outer peripheral surfaces of the reels 6a, 6b and 6c, "black 7" (arrangement number 2 of the left reel 6a etc.), "white 7" (arrangement number 9 of the left reel 6a etc.), ""BAR" (sequence number 16 of the left reel 6a), "Bell" (sequence number 0 of the left reel 6a, etc.), "Watermelon" (sequence number 20 of the left reel 6a, etc.), "Cherry" (sequence number of the left reel 6a) 6)), “replay” (seven number 1 of the left reel 6a) identifiable symbols, and “blank” (arrangement number 5 of the left reel 6a) in which no symbol is arranged, They are arranged in a predetermined order.

In FIG. 3, since “replay” is arranged within 5 consecutive frames on all reels 6a, 6b, 6c, it can always be stopped and displayed on the active line by the 4-frame pull-in stop control. Further, since the “bell” is arranged within 5 consecutive frames on the middle reel 6a and the right reel 6c, if a stop operation is performed from the left reel 6a (so-called forward push or scissor push), 4 frames pull-in stop control is performed. Therefore, it is always possible to stop display on the active line.
On the other hand, since the other winnings are composed of symbols that are not necessarily arranged within five consecutive frames, there are cases where the winning display cannot be stopped on the active line even if the pull-in stop control of four frames is performed. In other words, in order to stop and display these symbols on the active line, it is necessary to stop the reel stop buttons 24a, 24b, and 24c (press the target) aiming at the desired symbols.

FIG. 4 is a diagram showing the types of winnings in the slot machine 1 of the first embodiment, the symbol combination modes corresponding to each winning and the contents of winnings, and FIG. 5 is a diagram showing the special gaming state and the special gaming state end conditions. is there.
In the slot machine 1 of the first embodiment, as a special prize, a big bonus prize (BB prize) and a regular bonus prize (RB prize) are determined. In addition, as a BB prize, a black 7BB prize and a white 7BB prize are provided. A black 7BB winning flag and a white 7BB winning flag (a flag set when winning an internal lottery) and a state flag (a flag indicating the current gaming state) are treated separately. In the following description, when the black 7BB winning and the white 7BB winning are not distinguished, they are simply referred to as BB winning.
When a special prize is won internally, the winning flag is carried over to the next game and the special prize can be established in subsequent games even if the special prize cannot be established in the internally won game.

In the slot machine 1 according to the first embodiment, a bell prize, a watermelon prize, a cherry prize, a replay prize, and a special replay prize are defined as small prizes.
When a small winning combination is won internally, the small winning combination can be established only in the internally winning game. For example, when a small role winning (for example, watermelon winning) cannot be established due to the timing of the stop operation (so-called missing), the winning flag for this small role winning is cleared and is not carried over to the next game.

As shown in FIG. 4, the black 7BB winning is a winning that is established when a bonus symbol combination mode of “black 7-black 7-black 7” is formed on the active line. When the black 7BB winning is established, a black 7BB state as a special gaming state is generated. The payout of medals associated with the establishment of the Black 7BB prize is zero.
In the black 7BB state, for example, a game is executed in which the internal winning probability of the small prize winning is higher than that in the normal gaming state. Then, as shown in FIG. 5, the process ends when the total number of medals paid out to the player in the black 7BB state exceeds 350. In the black 7BB state, a JAC game (a game in which the internal winning probability of a predetermined winning combination is high when a JAC in winning is established) is repeatedly executed until the total number of medals to be paid out reaches a specified number. Alternatively, the JAC game may be executed in combination with a game having a high internal winning probability of the small role winning.
In addition, after the end of the black 7BB state, a replay time state (RT state) as a special gaming state occurs. That is, the internal winning of the black 7BB winning is one of the special game generation conditions for generating the RT state. Although details will be described later, in the RT state, for example, the internal winning probability of the replay winning is remarkably higher than in the normal gaming state. Then, as shown in FIG. 5, when the number of executed games reaches 100 games, when the BB prize is won internally, or when any special game ending condition when the RB prize is won internally is satisfied End.

  The white 7BB prize is a prize that is established when the bonus symbol combination mode of “white 7-white 7-white 7” is formed on the active line. When the white 7BB winning is established, a white 7BB state as a special gaming state is generated. The number of medals paid out when the white 7BB winning is established is zero. In the white 7BB state, control similar to that in the black 7BB state is performed. In the following description, when the black 7BB state and the white 7BB state are not distinguished, they are simply referred to as the BB state.

  The RB winning is a winning that is established when a bonus symbol combination mode of “BAR-Black 7-Black 7” is formed on the active line. When an RB winning is established, an RB state is generated as a special gaming state. The number of medals paid out when the RB winning is established is zero. In the RB state, for example, a game is executed in which the internal winning probability of the small role winning is higher than that in the normal gaming state. Then, as shown in FIG. 5, the process ends when the total number of medals for the player exceeds 50 in the RB state. In the RB state, the JAC game (a game in which the internal winning probability of a predetermined winning combination is high when a JAC in winning is established) is repeatedly executed until the total number of medals to be paid out reaches a specified number. Alternatively, a JAC game and a game with a high internal winning probability of small role winning may be executed in combination.

The Bell prize is a prize that is established when the symbol combination mode of “Bell-Bell-Bell” is formed on the active line. Six medals are obtained in the normal game state or the special game state, and 15 medals in the special game state. To be paid out. According to the symbol arrangement shown in Fig. 3, when you win the bell prize internally, if you push forward (stop order: left → middle → right) or scissors (stop order: left → right → middle), the bell prize will always be established. It becomes.
The watermelon prize is a prize that is established when the symbol combination mode of “watermelon-watermelon-watermelon” is formed on the active line. Six medals are obtained in the normal game state or the special game state, and 15 medals are obtained in the special game state. To be paid out. According to the symbol arrangement shown in FIG. 3, even if the watermelon prize is won internally, the watermelon prize may be missed if the pushing operation is not performed.

  The cherry winning is a winning that is established when the symbol combination mode of “cherry-ANY-ANY” is formed on the active line. In the normal gaming state or the special gaming state with respect to one effective line, In the special game state, four medals are paid out (stopped only on the middle line in the special game state). Here, “ANY” indicates that any symbol may be used. According to the symbol arrangement shown in FIG. 3, even if the cherry prize is won internally, the cherry prize may be missed if the pushing operation is not performed.

  The replay winning is a winning that is established when the symbol combination mode of “replay-replay-replay” is formed on the active line, and a replay game (replay game) that can be executed without a betting operation is given. . According to the symbol arrangement shown in FIG. 3, when the replay winning is won internally, the replay winning is always established regardless of the stop operation order.

The special replay winning is a winning in which the symbol combination mode of “black 7-replay-replay” can be formed on the active line, and a replay game is given and an RT state as a special gaming state is generated from the next game. . According to the symbol arrangement shown in FIG. 3, even if the special replay winning is won internally, the symbol combination mode corresponding to the special replay winning is not formed unless the pressing operation is performed. In this case, the symbol combination mode corresponding to the normal replay winning is formed in an effective line shape, the replay game is given, and the RT state as the special game state is generated from the next game.
That is, when the special replay winning is won internally, the special replay winning is established after the end of the game regardless of whether or not the symbol combination mode of “black 7-replay-replay” is formed in an effective line shape. It has become. The RT state generated when the special replay winning is established may be determined by lottery from a plurality of RT states, or may be fixed to a specific RT state (for example, the RT state most advantageous to the player). Good.

If an RT state (2 or 3 bets) in which a game can be executed with a smaller number of bets than in the normal gaming state occurs due to the establishment of a special replay win, the replay game will be internally won for a lose or win. After the game is interrupted, the required bet number in the RT state may be reflected, or the difference in number from the required bet number in the RT state generated when the special replay winning is established may be returned. Alternatively, after the special replay winning is established, the player enters the RT preparation mode (normal game state), and the RT state may be generated when a specific combination (for example, a bell winning) is established during the RT preparation mode. .
Also, a plurality of symbol combination modes corresponding to the special replay winning may be provided, and any symbol combination mode may be always derived when the special replay winning is internally won.

  In the slot machine of the first embodiment, in the same game, the special winning and the small winning combination can be won internally. In the case of overlapping internal winnings, the priority order of the winnings derived on the active line is, for example, replay winning (including special replay winning)> small role winning other than replay winning> special winning. The same applies to a case where a small winning prize is won internally in a game after winning an internal winning special prize.

When one of the above winnings is won internally by the internal lottery in the game control device 50, the symbol combination mode corresponding to the winning of the internal winning can be derived on the active line. On the other hand, if any winning is not won internally, the winning combination is lost, and the symbol combination corresponding to the winning is not formed on the active line.
In the normal gaming state, all the winnings including the BB winning and the RB winning are subject to internal lottery, and in the RT state, winnings other than the special replay winning are subject to internal lottery. In the BB state or the RB state, the bell winning, the watermelon winning, and the cherry winning are subject to the internal lottery.

FIG. 6 is a state transition diagram for explaining a gaming state in the slot machine 1 of the first embodiment. In the slot machine 1, it is assumed that the game is started in the normal gaming state ST10 immediately after the power is turned on.
In the normal gaming state ST10, when an RB winning is won internally, and the corresponding symbol combination mode is derived and winning is established, the process proceeds to the RB state ST11. When the BB winning is internally won and the corresponding symbol combination mode is derived and winning is established, the process proceeds to the BB state ST12. When the special replay winning is won internally and the game is ended, the process proceeds to the RT state ST13 regardless of whether or not the corresponding symbol combination mode is derived.

  Further, in the normal gaming state ST10, an internal lottery is performed according to a winning determination table in which the internal winning probabilities of various winnings become the internal winning probabilities shown in FIG. That is, the internal winning probability of the special winning is set to “1/450” for the black 7BB winning, “1/550” for the white 7BB winning, and “1/700” for the RB winning. The combined probability of internally winning the BB prize is “1 / 247.5”, and the combined probability of internally winning the special prize is “1 / 182.8”. In addition, the internal winning probability of the small role winning is 1/10 for the bell winning, 1/10 for the watermelon winning, 1/150 for the cherry winning, 1/7 for the replay winning, and the special replay winning. Is set to “1/1500”. The internal winning probabilities of various winnings shown in FIG. 7 are those when the bet number is 3, and the internal winning probability when the bet number is 2 is lower than the internal winning probability shown in FIG. The internal winning probability is even lower.

In the RB state ST11, for example, a game is executed in which the internal winning probability of the small prize winning is higher than that in the normal gaming state. Then, when the total number of medals paid out to the player exceeds 50, the RB state ST11 ends, and the normal game state ST10 is entered.
In the BB state ST12, for example, a game is executed in which the internal winning probability of the small role winning is higher than that in the normal gaming state. When the total number of medals paid out to the player exceeds 350, the BB state ST12 ends. If the type of the BB winning is the black 7BB winning, the process proceeds to the RT state ST13. If the type is the white 7BB winning, the process shifts to the normal gaming state ST10.
The internal winning probabilities of the bell winning, the watermelon winning and the cherry winning in the RB state ST11 or the BB state ST12 are not shown, but are set so that the combined probability is approximately 1.

  In the RT state ST13, a game is executed in which the internal winning probability of the replay winning is higher than that in the normal gaming state ST10. The RT state ST13 is generated when a special game occurrence condition is satisfied, that is, when a special replay winning is established in the normal game state ST10, or when the black 7BB state is ended. When the special game end condition is satisfied, that is, when the number of executed games reaches 100 games, when the BB winning is won internally, or when the RB winning is won internally, the RT state ST13 is ended, The game state ST10 is entered. In addition, when RT state ST13 is complete | finished by internal winning of a black 7BB prize, it will be in RT state ST13 again after completion | finish of black 7BB state.

The RT state ST13 is selected from a plurality of RT states having different internal winning probabilities for various winnings. In the first embodiment, three RT states (RT1 state ST131, RT2 state ST132, RT3 state ST133) having different internal winning probabilities for various winnings are prepared.
State flags (RT1 state flag, RT2 state flag, RT3 state flag) are provided corresponding to each of the RT1 state ST131, RT2 state ST132, and RT3 state ST133, and are referred to by internal lottery based on the state flags. The winning determination table is switched.

  In the RT1 state ST131, an internal lottery is performed according to a winning determination table in which the internal winning probabilities of various winnings become the internal winning probabilities shown in FIG. That is, the internal winning probability of the special winning is the same as that in the normal gaming state ST10, and the internal winning probability of the small role winning is “1/10” for the bell winning, “1/10” for the watermelon winning, 1/150 ”and the replay winning are set to“ 1 / 1.5 ”. Further, in the RT1 state ST131, the necessary bet number necessary for executing the game is fixed to 3.

  In the RT1 state ST131, since the internal winning probability of the replay winning is higher than that in the normal gaming state ST10, it is possible to overlap the game while suppressing the consumption amount of medals. Accordingly, it is possible to expect winning of the special prize while increasing the game value obtained by the establishment of the small part prize.

  In the RT2 state ST132, an internal lottery is performed according to a winning determination table in which the internal winning probabilities of various winnings become the internal winning probabilities shown in FIG. That is, the internal winning probability of the special prize is set to “1/180” for the black 7BB prize, “1/280” for the white 7BB prize, and “1/400” for the RB prize. The combined probability of internally winning the BB prize is “1 / 109.6”, and the combined probability of internally winning the special prize is “1 / 86.6”. In addition, the internal winning probability of the small role winning is set to “1/9” for the Bell winning, “1/9” for the watermelon winning, “1/100” for the cherry winning, and “1 / 1.5” for the replay winning. Has been. Further, in the RT2 state ST132, the necessary bet number necessary for executing the game is fixed to 2.

In the RT2 state ST132, as in the RT1 state ST131, the internal winning probability of the replay winning is higher than that in the normal gaming state ST10. It becomes possible. Accordingly, it is possible to expect winning of the special prize while increasing the game value obtained by the establishment of the small part prize.
Further, since the internal winning probability of the special winning is higher than that in the RT1 state ST131, the possibility that the special winning will be established during the RT2 state ST132 is increased.
Further, since the internal winning probability of the small part winning other than the replay winning is higher than that in the RT1 state ST131, the possibility that the small part winning is established during the RT2 state ST132 becomes high. Furthermore, since the required bet number is 2, the net increase number (the number of payouts−the number of bets) when the small role winning is established increases. Therefore, it can be expected that the gaming value is higher in the RT2 state ST132 than in the RT1 state ST131.
In the RT2 state ST132, if the active line is set according to the number of bets, the effective lines are reduced, and it is easy for the small prize winnings to be missed. Shall. In the following description, when the required bet number in the RT state (including the ART state) is 1 or 2, it is assumed that all enabling lines are similarly enabled.

  In the RT3 state ST133, an internal lottery is performed according to a winning determination table in which the internal winning probabilities of various winnings become the internal winning probabilities shown in FIG. That is, the internal winning probability of the special winning is set to “1/100” for the black 7BB winning, “1/150” for the white 7BB winning, and “1/250” for the RB winning. The combined probability of internally winning the BB prize is “1 / 60.0”, and the combined probability of internally winning the special prize is “1 / 48.4”. In addition, the internal winning probability for small role winning is set to "1/8" for Bell winning, "1/8" for watermelon winning, "1/85" for cherry winning, and "1 / 1.5" for replay winning Has been. Further, in the RT3 state ST133, the necessary bet number necessary for executing the game is fixed to 1.

In the RT3 state ST133, as in the RT1 state ST131 and the RT2 state ST132, the internal winning probability of the replay winning is higher than that in the normal gaming state ST10. Can be stacked. Accordingly, it is possible to expect winning of the special prize while increasing the game value obtained by the establishment of the small part prize.
Further, since the internal winning probability of the special winning is higher than that in the RT2 state ST132, the possibility that the special winning is established during the RT3 state ST133 is further increased.
Further, since the internal winning probability of the small role winning other than the replay winning is higher than that in the case of the RT2 state ST132, the possibility that the small role winning is established during the RT3 state ST133 is further increased. Furthermore, since the required bet number is 1, the net increase number (the number of payouts−the number of bets) when the small role winning is established increases. Therefore, in the RT3 state ST133, it can be expected that a higher game value can be obtained compared to the RT1 state ST131 and the RT2 state ST132.

  Next, with reference to FIGS. 11-14, the game control process by the game control apparatus 50 is demonstrated. This game control process includes a main process for comprehensively controlling the game and a timer interrupt process that is started at predetermined time intervals (for example, approximately every 2 msec) and performs input / output port processing, timer count processing, and the like. Here, only the main process will be described.

FIG. 11 is a flowchart illustrating an example of the main process. This main process is realized by the CPU 50a of the game control device 50 reading out and executing the main process program stored in the ROM 50b immediately after startup.
In step S1 of FIG. 11, initialization of game data stored in the RAM 50c of the game control device 50 is performed as initialization processing at the start of the program.
In step S2, a bet acceptance process is performed. In this bet receiving process, automatic insertion associated with establishment of a replay winning, medal insertion from the game medal slot 15, or input from credit is monitored.
In step S3, it is determined whether or not the start lever 21 has been operated. If it is determined that the start lever 21 has been operated, the process proceeds to step S4.

In step S4, an internal lottery process is performed based on the internal lottery random number. Specifically, it is executed according to the flowchart shown in FIG.
In step S101 in FIG. 12, an internal lottery random number is extracted, and in step S102, the number of active lines is acquired according to the bet number input in the bet receiving process (step S2 in FIG. 11).

In step S103, it is determined whether or not the current gaming state is the RB state or the BB state based on the state flag indicating the gaming state. If it is determined that the current gaming state is the RB state or the BB state, the process proceeds to step S104. If it is determined that the current gaming state is not the RB state or the BB state, the process proceeds to step S105.
Here, the state flag indicating the game state is a flag that is set in the game end process in step S9, and is a bonus state flag indicating the RB state or the BB state, and an RT state flag indicating the RT state. (RT1 status flag, RT2 status flag, RT3 status flag). When the bonus state flag or the RT state flag is not set, it means a normal gaming state.

In step S104, a winning determination table corresponding to the RB state or the BB state is acquired.
In step S105, based on the state flag indicating the gaming state, it is determined whether or not the current gaming state is the RT state (any one of the RT1 state, the RT2 state, and the RT3 state). When it is determined that the current gaming state is the RT state, the process proceeds to step S106, and when it is determined that the current gaming state is not the RT state, the process proceeds to step S107.
In step S106, a winning determination table corresponding to the generated RT state is acquired, and in step S107, a winning determination table corresponding to the normal gaming state is acquired.

In step S108, the random number for internal lottery extracted in step S101 is compared with the winning determination table acquired in step S104, S106 or S107.
In step S109, based on the comparison result in step S108, it is determined whether or not any winning is internally won. If it is determined that any winning has been won internally, the process proceeds to step S111. If it is determined that any winning has not been won internally, the process proceeds to step S110.
In step S110, the slip flag is set, and the process returns to the main process in FIG.

In step S111, based on the comparison result in step S108, it is determined whether or not the RB winning or the BB winning is won internally. If it is determined that the RB winning or BB winning is internally won, the process proceeds to step S113, and if it is determined that the RB winning or BB winning is not internally won (internal winning for the small role winning), the process proceeds to step S112. To do.
In step S112, a winning flag for a small winning combination won (a small winning combination flag, for example, a special replay winning flag in the case of internal winning for a special replay winning) is set, and the process returns to the main processing of FIG.
In step S113, a winning flag (bonus winning flag) of a special winning (either black 7BB winning, white 7BB winning or RB winning) won is set.
In step S114, an RT end flag for ending the RT state is set, and the process returns to the main process in FIG. It should be noted that if the current gaming state is not the RT state, that is, if a special prize is won internally in the normal gaming state, this process is not performed.

In FIG. 11, in step S5, the effective line information is set and the reels 6a, 6b, 6c are started to rotate after the minimum game interval time has elapsed, so that the reels 6a, 6b, 6c rotate at a constant speed. The motors 64a, 64b and 64c are controlled (reel fluctuation start processing).
In step S6, the stop positions of the reels 6a, 6b, 6c are determined according to the reel stop operation by the player, and the reels 6a, 6b, 6c are stopped at a predetermined position (reel fluctuation stop processing).

In step S7, the combination of symbols stopped and displayed on the active line is compared with the internal winning (the winning flag for which the winning flag is set), and it is determined whether or not the winning is achieved (winning determination) processing). If a winning is established, a payout number corresponding to the established winning is set.
In step S8, credit addition or medal payout in the game medal payout device 63 is controlled based on the payout number set in the win determination process win in step S7 (payout process).

In step S9, the number acquired in the BB state or the RB state, the game state at the end of one game, and the like are managed (game end process). Specifically, it is executed according to the flowchart shown in FIG.
In step S121 of FIG. 13, it is determined whether the current gaming state is the RB state or the BB state based on the state flag indicating the gaming state. If it is determined that the current gaming state is the RB state or the BB state, the process proceeds to step S129. If it is determined that the current gaming state is not the RB state or the BB state, the process proceeds to step S122.

In step S122, based on the determination result in the winning determination process (step S7 in FIG. 11), it is determined whether an RB winning or a BB winning is established. When it is determined that the RB winning or BB winning is established, the process proceeds to step S123, and when it is determined that the RB winning or BB winning is not established, the process proceeds to step S125.
In step S123, a state flag (bonus state flag) corresponding to the established special winning is set, and in step S124, the bonus winning flag is cleared.

In step S125, based on the set winning flag, it is determined whether or not a special replay winning has been established. If it is determined that a special replay winning is achieved, the process proceeds to step S126. If it is determined that a special replay winning is not achieved, the process proceeds to step S128.
In step S126, the RT state flag is set, and in step S127, "100" is set as an initial value in the RT number counter. When the RT state is generated by the establishment of the special replay winning, the RT state flag to be set by lottery may be determined from the RT1 state flag, the RT2 state flag, or the RT3 state flag, and any of the RT state flags May be generated in a fixed manner.

  In step S128, the small role winning flag (including the special replay winning flag) is cleared, and the process returns to the main process in FIG. If the RB winning or BB winning is not established even though the bonus winning flag is set, the bonus winning flag is not cleared and is carried over to the next game.

When it is determined in step S121 that the state is the RB state or the BB state, in step S129, the total payout number paid out in the RB state or the BB state is acquired. Specifically, the current payout number is added to the total payout number up to the previous time.
In step S130, the total payout number acquired in step S129 is compared with the specified number in the RB state or BB state (50 sheets in the RB state and 350 sheets in the BB state).
In step S131, based on the comparison result in step S130, it is determined whether or not the total payout number exceeds the specified number. If it is determined that the total payout number exceeds the specified number, the process proceeds to step S132. On the other hand, if it is determined that the total payout number does not exceed the prescribed number, the process shifts to step S128 to clear the small role winning flag, and then returns to the main process in FIG.

In step S132, based on the bonus state flag, it is determined whether or not the special gaming state that has occurred is a black 7BB state. If it is determined that the state is the black 7BB state, the process proceeds to step S133. If it is determined that the state is not the black 7BB state, that is, if the state is the white 7BB state or the RB state, the process proceeds to step S135.
In step S133, a continuous RT counter value indicating the gaming state when the black 7BB winning, which is a special game occurrence condition, is won internally, and the number of times the RT state continues (the number of times the black 7BB winning is continuously won). In response to the above, an RT state flag is set (RT state flag setting process), and in step S134, “100” is set as an initial value in the RT number counter.
In step S135, the bonus state flag is cleared to end the special game state. In step S128, the small role winning flag is cleared, and then the process returns to the main process in FIG.

In FIG. 11, in step S10, the number of executed games in the RT state is managed, and a process for ending the RT state when the special game end condition is satisfied is performed (RT state monitoring process). Specifically, it is executed according to the flowchart shown in FIG.
In step S141 in FIG. 14, it is determined whether or not the current gaming state is the RT state based on the state flag indicating the gaming state. If it is determined that the current gaming state is the RT state, the process proceeds to step S142. If it is determined that the current gaming state is not the RT state, the process returns to the main process of FIG.
In step S142, it is determined whether or not the RT end flag is set in accordance with the internal winning of the RB winning or the BB winning in step S114 of FIG. If it is determined that the RT end flag is set, the process proceeds to step S149. If it is determined that the RT end flag is not set, the process proceeds to step S143.

In step S143, an RT number counter value indicating the number of games executed in the RT state is acquired, and in step S144, the RT number counter value is decremented by one.
In step S145, it is determined whether or not the RT number counter value is smaller than zero. Then, when it is determined that the RT number counter value is smaller than 0, that is, when the number of games executed in the RT state reaches the prescribed game number (here, 100 games), the process proceeds to step S146, and the RT number counter value is If it is determined that the number is 0 or more, the process returns to the main process in FIG.

In step S146, the RT state flag is cleared. When the RT state flag is cleared, the normal game state is entered from the next game. If the RT end flag is set, the RT end flag is cleared together with the RT state flag.
In step S147, the RT counter value is reset, and in step S148, the continuous RT counter value indicating the number of times the RT state continues is reset. Then, the process returns to the main process in FIG.
Here, the continuous RT counter value indicates the number of times that the black 7BB winning is established during the RT state and the RT state is continued, and the RT state generated by the establishment of the special replay winning is not included in the number of continuing times. Treat as a thing.

In step S149, it is determined whether or not the RT state is continued based on the state of the black 7BB winning flag or the black 7BB state flag. If it is determined that the RT state is continued, the process proceeds to step S151. If it is determined that the RT state is not continued, the process proceeds to step S150.
In step S150, the continuous RT counter value is reset. In step S151, the RT state flag is cleared. In step S152, the RT number counter is reset. Then, the process returns to the main process in FIG.
In this way, a series of game control processes (main processes) are executed.

As described above, the slot machine 1 has the internal lottery means (internal lottery process executed by the game control device 50, step S4 in FIG. 11) for drawing whether or not a prize is won in accordance with the game start operation by the player. The game is executed by variably displaying the plurality of reels 6a, 6b, 6c in accordance with the game start operation, and the plurality of reels 6a, 6b, Change display means for performing stop control of 6c (reel fluctuation start process and reel fluctuation stop process executed by the game control device 50, steps S5 and S6 in FIG. 11), and special prizes (RB prize, black 7BB prize, When a special symbol combination mode determined in advance by symbols arranged on a plurality of reels is won, a large amount is awarded to the player. Grantable game media special game state (RB state, BB state) special game control means for generating a (the game control unit 50), and a.
Further, special game control means (game control device 50) for controlling generation and execution of a special game state (RT state) different from the special game state is provided. Then, the special game control means has a plurality of special games with different special winning winning probabilities in the internal lottery based on the establishment of the special game generating conditions for generating the special gaming state (special replay winning or black 7BB winning internal winning). Any one of the gaming states (RT1 state, RT2 state, RT3 state) is selected and generated (RT state flag setting process, step S133 in FIG. 13).

According to the slot machine 1 of the first embodiment, since the winning probability of the special winning in the special gaming state (RT state) is higher than that in the normal gaming state, the expected value when the special gaming state occurs (probably Expected number of acquisitions) increases. On the other hand, special game end conditions (for example, the prescribed number of games in the RT state) are set so that the average number of games executed in one special game state is shortened in order to average machine discounts. There is little possibility that the player will be restrained for a long time due to the occurrence of the state.
Therefore, a slot machine having a new gaming property that can easily enjoy a game for a short time without restraining the player for a long time due to the occurrence of a special gaming state is realized.

Further, the special game control means sets the required bet number necessary for executing the game for each of a plurality of special game states (RT1 state, RT2 state, RT3 state). More specifically, the smaller the required bet number is set for the special game state having a higher probability of winning the special prize (RT1 state: bet number 3, RT2 state: bet number 2, RT3 state: bet number 1).
As a result, a new gameability is realized in which the net increase in number when the small role winning other than the replay winning is established in the special gaming state is changed depending on the type of the special gaming state to be generated. Can be increased.

Further, the special game control means selects and generates one of a plurality of special game states when a special prize (black 7BB prize) that is a special game generation condition is established.
As a result, a large amount of game media can be obtained with the establishment of the special prize, and a special game state advantageous to the player is generated, and the player's gambling feeling is moderately given. Can be increased.

In the slot machine 1 of the first embodiment, the RT state as the special game state can be generated in various patterns. An example of an RT state occurrence pattern will be described below.
[RT generation pattern 1]
FIG. 15 is a diagram illustrating an example of an RT state occurrence pattern. In the example shown in FIG. 15, when the black 7BB winning is established in the normal gaming state, the RT1 state is generated after the end of the BB state. Next, when the black 7BB winning is established in the RT1 state, an RT2 state that is more advantageous than the RT1 state is generated after the end of the BB state. Further, when the black 7BB winning is established in the RT2 state, an RT3 state that is more advantageous than the RT2 state is generated after the BB state is finished. When the black 7BB winning is established in the RT3 state, the most advantageous RT3 state is continuously generated.
That is, in the RT generation pattern 1, every time a black 7BB winning is established in the RT state, an RT state that is advantageous to the player is selected and generated.

In this case, the RT state flag setting process (step S133 in FIG. 13) is executed according to the flowchart shown in FIG.
In step S201 in FIG. 16, a continuous RT counter value is acquired.
In step S202, 1 is added to the continuous RT counter value. When the black 7BB winning is established in the normal gaming state, the continuous RT counter value is 1, and when the black 7BB winning is established in the first RT state, the continuous RT counter value is 2. Thus, the continuous RT counter value increases by 1 each time a black 7BB winning is established during the RT state.

In step S203, it is determined whether or not the continuous RT counter value is 1. When it is determined that the continuous RT counter value is 1, that is, the RT state to be generated is the first RT state, the process proceeds to step S204 and the RT1 state flag is set.
If it is determined in step S203 that the continuous RT counter value is not 1, the process proceeds to step S205. In step S205, it is determined whether the continuous RT counter value is 2. If it is determined that the continuous RT counter value is 2, that is, the RT state to be generated is the second RT state, the process proceeds to step S206 and the RT2 state flag is set.
If it is determined in step S205 that the continuous RT counter value is not 2, that is, the RT state to be generated is the third or later RT state, the process proceeds to step S207 and the RT3 state flag is set.

  In the internal lottery process, the winning determination table corresponding to the generated RT state is referred to based on the RT1 state flag set in step S204, the RT2 state flag set in step S206, and the RT3 state flag set in step S207. (Step S106 in FIG. 12).

As described above, in the RT state generation pattern 1, the special game control means, when the special winning state (black 7BB winning) which is a special game generating condition is internally won in the special gaming state (RT state), A special gaming state is generated in which the winning probability is higher than the winning probability in the special gaming state. For example, the RT2 state is generated when the black 7BB winning is internally won during the RT1 state, and the RT3 state is generated when the black 7BB winning is internally winning during the RT2 state.
Thus, whenever a special prize that is a special game occurrence condition is established during the special game state, the player is promoted to a game state advantageous to the player, so that the player's sense of expectation for the special game state can be further enhanced.

[RT generation pattern 2]
FIG. 17 is a diagram illustrating another example of an RT state occurrence pattern. In the example shown in FIG. 17, when the black 7BB winning is established in the normal gaming state, the RT1 state is generated after the BB state is finished. Next, when the black 7BB winning is established in the RT1 state, an RT2 state that is more advantageous than the RT1 state is generated after the end of the BB state. Further, when the black 7BB winning is established in the RT2 state, an RT3 state that is more advantageous than the RT2 state is generated after the BB state is finished. When the black 7BB winning is established in the RT3 state, the RT1 state is generated after the end of the BB state.
That is, in the RT generation pattern 2, every time a black 7BB winning is established in the RT state, an RT state that is advantageous to the player is selected and generated, while the next most advantageous RT3 state returns to the RT1 state, The RT1 state → RT2 state → RT3 state loops.

In this case, the RT state flag setting process (step S133 in FIG. 13) is executed according to the flowchart shown in FIG.
In step S221 in FIG. 18, a continuous RT counter value is acquired.
In step S222, it is determined whether or not the continuous RT counter value is 3. If it is determined that the continuous RT counter value is 3, the process proceeds to step S223 and the continuous counter value is reset. On the other hand, if it is determined that the continuous RT counter value is not 3 (continuous counter value = 0, 1, 2), the process proceeds to step S224.
In step S224, 1 is added to the continuous RT counter value. In the 3n (n is an integer) RT state (normal game state when n = 0), if a black 7BB winning is achieved, the continuous RT counter value is 1, and in the (3n + 1) th RT state, the black 7BB winning is If it is established, the continuous RT counter value is 2, and if the black 7BB winning is established in the (3n + 2) th RT state, the continuous RT counter value is 3.

In step S225, it is determined whether or not the continuous RT counter value is 1. If it is determined that the continuous RT counter value is 1, the process proceeds to step S226, and the RT1 status flag is set.
If it is determined in step S225 that the continuous RT counter value is not 1, the process proceeds to step S227. In step S227, it is determined whether or not the continuous RT counter value is 2. If it is determined that the continuous RT counter value is 2, the process proceeds to step S228, and the RT2 status flag is set.
If it is determined in step S227 that the continuous RT counter value is not 2 (continuous RT counter value = 3), the process proceeds to step S229 and the RT3 state flag is set.

  In the internal lottery process, the winning determination table corresponding to the generated RT state is referenced based on the RT1 state flag set in step S226, the RT2 state flag set in step S228, and the RT3 state flag set in step S229. (Step S106 in FIG. 12).

As described above, in the RT state occurrence pattern 2, the special game control means is internally set in the special prize (black 7BB prize) which becomes a special game occurrence condition during the special game state (RT3 state) with the highest probability of winning the special prize. When winning, a special gaming state (RT1 state) having the lowest winning probability of special winning is generated.
As a result, the special gaming state that is most advantageous for the player will not occur continuously, so that the gambling ability of the gaming machine is suppressed, and the player's gambling feeling is excessively beaten due to the biased medal. Can be prevented.

[RT generation pattern 3]
FIG. 19 is a diagram illustrating another example of an RT state occurrence pattern. In the example shown in FIG. 19, when the black 7BB winning is established in the normal gaming state, the RT2 state or the RT3 state is generated after the end of the BB state (the first RT state). Similarly, when the black 7BB winning is established in the first to third RT states, the RT2 state or the RT3 state is generated after the end of the BB state (the second to fourth RT states). When the black 7BB winning is established in the fourth and subsequent RT states, the RT1 state is generated after the end of the BB state.
That is, in the RT generation pattern 3, when the first to fourth RT states are generated, the RT2 state or the RT3 state is set, and when the fifth RT state is generated, the RT1 state is set.

In this case, the RT state flag setting process (step S133 in FIG. 13) is executed according to the flowchart shown in FIG.
In step S241 in FIG. 20, a continuous RT counter value is acquired.
In step S242, 1 is added to the continuous RT counter value. When the black 7BB winning is established in the normal gaming state, the continuous RT counter value is 1, and when the black 7BB winning is established in the first RT state, the continuous RT counter value is 2. Thus, the continuous RT counter value increases by 1 each time a black 7BB winning is established during the RT state.

In step S243, it is determined whether the continuous RT counter value is less than 5. If it is determined that the continuous RT counter value is less than 5 (the black 7BB winning is established in the normal gaming state or the first to third RT states), the process proceeds to step S244 and the RT2 state flag or the RT3 state flag is set. set. Which RT state flag is set is determined by lottery, for example.
If it is determined in step S243 that the continuous RT counter value is not less than 5 (the black 7BB winning is established in the fourth and subsequent RT states), the process proceeds to step S245 and the RT1 state flag is set.

  In the internal lottery process, the winning determination table corresponding to the generated RT state is referred to based on the RT2 state flag or the RT3 state flag set in step S244 and the RT1 state flag set in step S245 ( Step S106 in FIG.

In this way, in the RT state generation pattern 3, the special game control means internally wins a special prize (black 7BB prize) that becomes a special game generation condition during the special game state (RT1 state or RT2 state), and the special game. When the number of state continuations reaches a predetermined number (here, 5 times), a special gaming state (RT1 state) having the lowest winning probability of the special winning is generated.
Thereby, since a medal can be suppressed when the special gaming state is continuously generated many times, the gambling ability of the gaming machine is suppressed, and the player's gambling feeling can be prevented from being excessively beaten.

[Other RT generation patterns]
RT generation patterns applicable in the slot machine 1 of the first embodiment are not limited to the RT generation patterns 1 to 3 described above. For example, RT generation patterns 1 to 3 can be applied in combination, and when a special prize (black 7BB prize) as a special game generation condition is established, which of the RT1 to RT3 states is generated by lottery every time You may decide.
In addition, when the special replay winning is selected in the RT state internal lottery and the special replay winning is established during the RT state, the special replay winning is performed after the running RT state is ended by the establishment of the special game end condition. A new RT state may be generated in accordance with the establishment of (so-called RT state stock).

[Second Embodiment]
The slot machine of the second embodiment has almost the same configuration as the slot machine 1 of the first embodiment. Here, points different from the slot machine 1 of the first embodiment will be mainly described.
In the slot machine of the second embodiment, a plurality of types of special winnings that are special game generation conditions are prepared, and the special game control means generates a special game state that is generated according to the type of the special winning winning in the internal lottery. Is to decide.

  FIG. 21 is a diagram showing the types of winnings in the slot machine according to the second embodiment, symbol combination modes corresponding to the winnings and winning contents, and FIG. 22 is a diagram showing the special game state and the special game state end conditions. . Since the RB winning, the Bell winning, the watermelon winning, the cherry winning, the replay winning, and the special replay winning are the same as those in the first embodiment, the description thereof is omitted.

As shown in FIG. 21, in the slot machine of the second embodiment, black 7BB winning and white 7BB winning are provided as BB winning. The winning flag and the status flag for the black 7BB winning and the white 7BB winning are handled separately.
After completion of the black 7BB state or the white 7BB state, an RT state as a special game state occurs in any case. However, the generated RT state is different. After completion of the black 7BB state, an RT2 state in which the internal winning probability of the special prize is higher than the normal gaming state occurs, and after the white 7BB state, the internal winning probability of the special prize is low compared to the RT2 state. A state is supposed to occur.

FIG. 23 is a state transition diagram for explaining a gaming state in the slot machine of the second embodiment. In the slot machine of the second embodiment, it is assumed that the game is started in the normal gaming state ST20 immediately after the power is turned on.
Since the normal gaming state ST20 and the RB state ST21 are the same as those in the first embodiment, description thereof will be omitted. In the normal gaming state ST20, an internal lottery is performed according to a winning determination table having internal winning probabilities shown in FIG.

  In the BB state ST22, for example, a game is executed in which the internal winning probability of the small prize winning is higher than that in the normal gaming state. When the total number of medals paid out to the player exceeds 350, the BB state ST22 ends. Then, after the BB state is completed, the process shifts to the RT state ST23, but when the type of the BB winning is the white 7BB winning, the process shifts to the RT1 state ST231, and when the black BB winning is, the process shifts to the RT2 state ST232. To do.

In the RT1 state ST231, an internal lottery is performed according to a winning determination table in which the internal winning probabilities of various winnings become the internal winning probabilities shown in FIG. That is, the internal winning probability of the special winning is set to “1/450” for the black 7BB winning, “1/550” for the white 7BB winning, and “1/700” for the RB winning. The combined probability of internally winning the BB prize is “1 / 247.5”, and the combined probability of internally winning the special prize is “1 / 182.8”. Also, the internal winning probability for the small role winning is set to "1/6" for the Bell winning, "1/6" for the watermelon winning, "1/85" for the cherry winning, and "1 / 1.5" for the replay winning Has been. Further, in the RT1 state ST231, the necessary bet number necessary for executing the game is fixed to 2.
In the RT1 state ST231, as shown in FIG. 22, when the number of executed games reaches 100 games, any special game end condition is established when the BB winning is won internally or when the RB winning is won internally. When the game is over, the game is ended and the normal game state ST20 is entered.

In the RT1 state ST231, since the internal winning probability of the replay winning is higher than that in the normal gaming state ST20, it is possible to overlap the games while suppressing the consumption amount of medals. Accordingly, it is possible to expect winning of the special prize while increasing the game value obtained by the establishment of the small part prize.
Further, since the internal winning probability of the small role winning other than the replay winning is higher than that in the normal gaming state ST20, there is a high possibility that the small role winning is established during the RT1 state ST231. Furthermore, since the required bet number is 2, the net increase number (the number of payouts−the number of bets) when the small role winning is established increases. Therefore, in the RT1 state ST231, it can be expected that a high gaming value is obtained as compared with the normal gaming state.

In the RT2 state ST232, an internal lottery is performed according to a winning determination table in which the internal winning probabilities of various winnings become the internal winning probabilities shown in FIG. That is, the internal winning probability of the special winning is set to “1/100” for the black 7BB winning, “1/150” for the white 7BB winning, and “1/250” for the RB winning. The combined probability of internally winning the BB prize is “1 / 60.0”, and the combined probability of internally winning the special prize is “1 / 48.4”. Also, the internal winning probability for the small role winning is set to "1/6" for the Bell winning, "1/6" for the watermelon winning, "1/85" for the cherry winning, and "1 / 1.5" for the replay winning Has been. Further, in the RT2 state ST232, the necessary bet number necessary for executing the game is fixed to 1.
As shown in FIG. 22, the RT2 state is ended when any special game end condition is established when the BB winning is won internally or when the RB winning is won internally. That is, the RT2 state is continued until a special prize is won internally. It should be noted that the RT2 state occurs when the special replay winning is won internally.

In the RT2 state ST232, as in the RT1 state ST231, since the internal winning probability of the replay winning is higher than that in the normal gaming state ST20, the game can be repeated while suppressing the consumption of medals. It becomes possible. Accordingly, it is possible to expect winning of the special prize while increasing the game value obtained by the establishment of the small part prize.
Further, since the internal winning probability of the special winning is higher than that in the RT1 state ST231, the possibility that the special winning is established during the RT2 state ST232 is increased. Furthermore, since the required bet number is 1, the net increase number (the number of payouts−the number of bets) when the small role winning is established increases. Therefore, in the RT2 state ST232, it can be expected that a higher game value can be obtained compared to the RT1 state ST231.

  In the slot machine of the second embodiment, game control processing is performed in substantially the same manner as in the first embodiment. Part of the game end process is different from the first embodiment (see FIG. 13). In the second embodiment, the game end process is executed according to the flowchart of FIG.

  In step S301 in FIG. 26, it is determined whether the current gaming state is the RB state or the BB state based on the state flag indicating the gaming state. When it is determined that the current gaming state is the RB state or the BB state, the process proceeds to step S309, and when it is determined that the current gaming state is not the RB state or the BB state, the process proceeds to step S302.

In step S302, based on the determination result in the winning determination process (step S7 in FIG. 11), it is determined whether an RB winning or a BB winning is established. When it is determined that the RB winning or BB winning is established, the process proceeds to step S303, and when it is determined that the RB winning or BB winning is not established, the process proceeds to step S305.
In step S303, a state flag (bonus state flag) corresponding to the established special winning is set, and in step S304, the bonus winning flag is cleared.

In step S305, based on the set winning flag, it is determined whether or not a special replay winning has been established. If it is determined that a special replay winning is achieved, the process proceeds to step S306. If it is determined that a special replay winning is not achieved, the process proceeds to step S308.
In step S306, the RT2 status flag is set, and in step S307, “10000” is set as an initial value in the RT number counter. By setting the initial value of the RT number counter to “10000”, the RT2 state is reliably continued until the next special prize is established.

  In step S308, the small role winning flag is cleared, and the process returns to the main process in FIG. If the RB winning or BB winning is not established even though the bonus winning flag is set, the bonus winning flag is not cleared and is carried over to the next game.

If it is determined in step S301 that the state is the RB state or the BB state, in step S309, the total payout number paid out in the RB state or the BB state is acquired. Specifically, the current payout number is added to the total payout number up to the previous time.
In step S310, the total payout number acquired in step S309 is compared with the specified number in the generated RB state or BB state (50 sheets in the RB state and 350 sheets in the BB state).
In step S311, based on the comparison result in step S310, it is determined whether or not the total payout number exceeds the specified number. If it is determined that the total payout number exceeds the specified number, the process proceeds to step S312. On the other hand, if it is determined that the total payout number does not exceed the specified number, the process proceeds to step S308 to clear the small role winning flag, and then returns to the main process in FIG.

In step S312, based on the bonus state flag, it is determined whether or not the special gaming state that has occurred is the white 7BB state. If it is determined that the white 7BB state is set, the process proceeds to step S313. If it is determined that the white 7BB state is not set, the process shifts to step S315.
In step S313, the RT1 status flag is set, and in step S314, the RT number counter is set to “100” as an initial value.
In step S315, based on the bonus state flag, it is determined whether or not the special gaming state that has occurred is a black 7BB state. If it is determined that the state is the black 7BB state, the process proceeds to step S316. If it is determined that the state is not the black 7BB state, the process proceeds to step S318.
In step S316, the RT2 status flag is set, and in step S317, “10000” is set as an initial value in the RT number counter.
In step S318, the bonus state flag is cleared to end the special game state. In step S308, the small role winning flag is cleared, and then the process returns to the main process in FIG.

  In the internal lottery process, the winning determination table corresponding to the generated RT state is referred to based on the RT1 state flag set in step S313 and the RT2 state flag set in step S316 (step in FIG. 12). S106).

As described above, in the second embodiment, the special game control means determines the special game state to be generated according to the type of the special prize won in the internal lottery (black 7BB prize or white 7BB prize). For example, when the black 7BB winning is won internally, the RT2 state is generated after the BB state, and when the white 7BB winning is internally won, the RT1 state is generated after the BB state.
As a result, the player becomes interested in the type of the special prize won internally, so that the player's interest in the game can be enhanced.

Note that the internal winning probability of the replay winning may be changed between the RT1 state and the RT2 state. For example, if the internal winning probability of the replay winning in the RT1 state is “1 / 6.9” (substantially the same as the normal gaming state), the expected value is greatly different between the RT1 state and the RT2 state. Can be drawn.
Further, the RT2 state continues until the next special winning is established, but may be ended with a predetermined number of games (for example, 100 games).

  In the second embodiment, the internal winning probabilities of the small winnings in the RT1 state and the RT2 state may be the same, and the payout numbers may be set differently. For example, the number of payouts for the Bell winning and Watermelon winnings is 10 in the RT1 state and 15 in the RT2 state (the number of payouts in the normal gaming state is 6). Further, the number of cherries to be paid out is 5 in the RT1 state and 10 in the RT2 state (the number of payouts in the normal gaming state is 2).

[Third Embodiment]
The slot machine of the third embodiment has almost the same configuration as the slot machine 1 of the first embodiment. Here, points different from the slot machine 1 of the first embodiment will be mainly described.
In the third embodiment, a plurality of types of special prizes that are conditions for generating special games are prepared, and the special game control means determines the special game state to be generated according to the type of special prize won in the internal lottery. It is like that.
Also, an RT end combination (RT end replay winning) as a special game end condition is provided, and when the RT end replay winning is established during the RT state, the RT state is ended.

In addition, when a predetermined condition (ART generation condition) is established in the RT state, a state (ART state) of notifying the type of small part winning as assist information when an internal winning is made for a small part winning that may be missed. (ART function). In the ART state, the player can surely win the small winning combination that is won internally by pushing the top.
The effect control device 70 transmits the control signal for displaying the assist information to the image display device 3 based on the internal winning state (three-option bell winning flag) transmitted from the game control device 50, thereby providing the ART function. Is realized.

  FIG. 27 shows the types of winning in the slot machine of the third embodiment, the pattern combination corresponding to each winning, and the contents of winning, and FIG. 28 shows the special game state and the special game state end conditions. . Since the RB winning, the Bell winning, the watermelon winning, the cherry winning, the replay winning, and the special replay winning are the same as those in the first embodiment, the description thereof is omitted.

As shown in FIG. 27, in the slot machine of the third embodiment, BB1 winning, BB2 winning, BB3 winning and BB4 winning are provided as BB winning. The BB1 to BB4 winning flags and status flags are distinguished from each other.
The BB1 to BB4 prizes are "Black 7-White 7-White 7", "White 7-White 7-Black 7", "Black 7-Black 7-Black 7", "White 7-White 7-White 7", respectively. This is a winning that is established when the bonus symbol combination mode is formed on the active line. When the BB winning is established, a BB state as a special gaming state is generated. The number of medals paid out when the BB winning is established is zero.
In the BB state, for example, a game is executed in which the internal winning probability of the small role winning is higher than that in the normal gaming state. Then, as shown in FIG. 28, the process ends when the total number of medals paid out to the player in the BB1 state exceeds 350.
Further, after the end of the BB1 to BB3 states, a replay time state (RT state) as a special gaming state occurs. That is, the internal winning of the BB1 to BB3 winnings is one of the special game generation conditions for generating the RT state.

  Black 7 bell prize, white 7 bell prize, BAR bell prize (hereinafter referred to as 3 choice bell prize if not distinguished) are “black 7-bell-bell”, “white 7-bell-bell”, “BAR”, respectively. The winning is established when the symbol combination mode of “-bell-bell” is formed on the active line, and 9 medals are paid out in the normal gaming state or the special gaming state and 15 medals in the special gaming state. According to the symbol arrangement shown in FIG. 3, the 3 choice bell winning may be missed even if an internal winning is not performed. In the ART state, when one of the three choice bell winnings is won internally, information indicating the type of winning winning (for example, aim for “black 7” on the left reel) is notified.

  The RT end replay winning is a winning that is established when the symbol combination mode of “replay-replay-replay” is formed on the upper effective line. The RT end replay winning is subject to internal lottery only in the RT state or the ART state. When the RT end replay winning is established, a replay game is given and the RT state is ended. On the other hand, when the RT end replay winning is won internally but is not established, the replay game is given and the RT state is continued.

  The RT end replay winning is established or not established based on the player's reel stop operation (push order) in the game that is internally won for the winning. Specifically, when the RT end replay winning is won internally, the push order (for example, left reel / right reel that was first stopped) is determined by lottery so that the RT end replay winning can be avoided. Is done. If the player's pressing order is correct (same as the determined pressing order), the replay winning combination pattern is formed on the active line other than the upper stage, and the end of the RT state is avoided. (FIG. 29 (b). On the other hand, if the player's pushing order is incorrect, a symbol combination mode of replay winning is formed on the upper active line, and the RT state is terminated (FIG. 29 ( a)).

  The ART start replay winning is a winning that is established when the symbol combination aspect of “replay-replay-replay” is formed on the middle effective line. The ART start replay winning is subject to internal lottery only in the RT state. When the ART start replay winning is established, a replay game is given and an ART state is generated. On the other hand, if the internal winning of the ART start replay winning is not established, the replay game is given and the RT state is continued.

  The ART start replay winning is established or not established based on the player's reel stop operation (push order) in the game that is internally won for the winning. Specifically, when the ART start replay prize is won internally, the push order in which the ART start replay prize can be established (for example, the first stop operation is the left reel / middle reel / right reel) is determined by lottery. It is determined. When the player's pressing order is correct (same as the determined pressing order), a replay winning symbol combination mode is formed on the middle active line, and an ART state is generated (FIG. 30 ( a)). On the other hand, if the player's pushing order is incorrect, a replay winning combination pattern is formed on the active line other than the middle row, and the RT state is continued (FIG. 30 (b)).

FIG. 31 is a state transition diagram for explaining a gaming state in the slot machine of the third embodiment. In the slot machine of the third embodiment, it is assumed that the game is started in the normal gaming state ST30 immediately after the power is turned on.
Since the normal gaming state ST30 and the RB state ST31 are the same as those in the first embodiment, description thereof will be omitted. However, in the normal gaming state ST30, an internal lottery is performed according to a winning determination table having internal winning probabilities shown in FIG. That is, the internal winning probabilities of the special winning are set to “1/1350” for the BB1 to BB3 winnings, “1/550” for the BB4 winnings, and “1/700” for the RB winnings, respectively. The combined probability of internally winning the BB prize is “1 / 247.5”, and the combined probability of internally winning the special prize is “1 / 182.8”. As for the internal winning probability of the small role winning, the 3 choice bell winning is “1/15” (combination probability is 1/5), the bell winning is “1/10”, the watermelon winning is “1/10”, cherry The winning is set to “1/150”, the replay winning is set to “1/7”, and the special replay winning is set to “1/1500”. The internal winning probabilities of various winnings shown in FIG. 32 are those when the bet number is 3, and the internal winning probability when the bet number is 2 is lower than the internal winning probability shown in FIG. The internal winning probability is even lower.

In the BB state ST32, for example, a game is executed in which the internal winning probability of the small prize winning is higher than that in the normal gaming state. When the total number of medals paid out to the player exceeds 350, the BB state ST32 ends. Then, after the BB state is completed, the process proceeds to the RT state ST33, but when the type of the BB winning is BB1, the process proceeds to the RT1 state ST331, and when the BB winning is, the process proceeds to the RT2 state ST232, When it is BB3 winning, it moves to RT3 state ST333.
In the BB1 to BB3 states, in the RT state ST33 that occurs after the end of the BB state, whether the push order for avoiding the establishment of the RT end replay prize and the push order for establishing the ART start replay prize is notified. You may make it perform the auxiliary game which draws lots.

  In the RT1 state ST331, an internal lottery is performed according to a winning determination table in which the internal winning probabilities of various winnings become the internal winning probabilities shown in FIG. That is, the internal winning probabilities of the special prize, the 3 choice bell prize, the watermelon prize, and the cherry prize are the same as those in the normal gaming state ST30, the replay prize is “1 / 3.8”, and the RT end replay prize is “1/5”. "ART start replay winning is set to" 1/20 ". Further, in the RT1 state ST331, the necessary bet number necessary for executing the game is fixed to 3.

  In the RT1 state ST331, when the ART start replay winning is established, the state shifts to the ART1 state ST341. On the other hand, as shown in FIG. 28, the RT1 state ST331 is established when any of the special game ending conditions when the BB winning is won internally, when the RB winning is won internally, or when the RT end replay winning is established. Is ended, and the state shifts to the normal gaming state ST30.

In the ART1 state ST341, an internal lottery is performed according to a winning determination table in which the internal winning probabilities of various winnings become the internal winning probabilities shown in FIG. That is, the internal winning probability in the case of RT1 state ST331 is succeeded only by the ART start replay winning being excluded from the target of the internal lottery. Also, in the ART1 state ST341, the type of internally selected 3-option bell winning and the pressing order for avoiding the RT end replay winning are notified.
In the ART1 state ST341, as shown in FIG. 28, when the number of executed games reaches 30 games, the ART1 state ST341 ends, and the process proceeds to the RT1 state ST331. On the other hand, when any special game end condition is satisfied when the BB prize is won internally, when the RB prize is won internally, or when the RT end replay prize is established, the ART1 state ST341 is terminated and the normal game state Move on to ST30. However, as long as the player follows the notified push order, the ART1 state ST341 will not end due to the establishment of the RT end replay winning.

In the RT1 state ST331 and the ART state ST341, the internal winning probability (replay winning, RT end replay winning, ART start replay winning combined probability) of the replay winning is higher than that in the normal gaming state ST30. Therefore, it is possible to keep playing games while reducing the consumption of medals. Accordingly, it is possible to expect winning of the special prize while increasing the game value obtained by the establishment of the small part prize.
Further, in the ART1 state ST341, the type of the internally selected 3-option bell winning is notified, so that more game media can be acquired than in the RT1 state ST331.

  In the RT2 state ST332, an internal lottery is performed according to a winning determination table in which the internal winning probabilities of various winnings become the internal winning probabilities shown in FIG. That is, the internal winning probabilities of the special winning are set to “1/540” for the BB1 to BB3 winnings, “1/280” for the BB4 winnings, and “1/400” for the RB winnings, respectively. The combined probability of internally winning the BB prize is “1 / 109.6”, and the combined probability of internally winning the special prize is “1 / 86.6”. In addition, the internal winning probability of the small role winning is “1/15” for the 3-choice bell winning (same as in the RT1 state), “1/9” for the bell winning, “1/9” for the watermelon winning, cherry The winning is set to “1/100”, the replay winning is set to “1 / 3.2”, the RT end replay winning is set to “1 / 6.7”, and the ART start replay winning is set to “1/20”. Further, in the RT2 state ST332, the necessary bet number necessary for executing the game is fixed to 2.

  In the RT2 state ST332, when the ART start replay winning is established, the state shifts to the ART2 state ST342. On the other hand, as shown in FIG. 28, the RT2 state ST332 when any of the special game ending conditions when the BB winning is won internally, when the RB winning is won internally, or when the RT end replay winning is established is satisfied. Is ended, and the state shifts to the normal gaming state ST30.

In the ART2 state ST342, an internal lottery is performed according to a winning determination table in which the internal winning probabilities of various winnings become the internal winning probabilities shown in FIG. That is, the internal winning probability in the case of RT2 state ST332 is inherited only by the ART start replay winning being excluded from the target of the internal lottery. Also, in the ART2 state ST342, the type of the 3-option bell winning that was won internally and the push order for avoiding the RT end replay winning are notified.
In the ART2 state ST342, as shown in FIG. 28, when the number of executed games reaches 30 games, the ART2 state ST342 ends, and the process proceeds to the RT2 state ST332. On the other hand, if any special game end condition is satisfied when the BB winning is won internally, when the RB winning is won internally, or when the RT end replay winning is established, the ART2 state ST342 is ended, and the normal gaming state Move on to ST30. However, as long as the player follows the notified push order, the ART2 state ST342 will not be terminated due to the completion of the RT end replay winning.

In RT2 state ST332 and ART2 state ST342, as in RT1 state ST331, the internal winning probability of replay winning (replay winning, RT end replay winning, ART start replay winning combined probability) is compared with that in normal gaming state ST30. Since the probability is high, it is possible to keep playing games while reducing the consumption of medals. Accordingly, it is possible to expect winning of the special prize while increasing the game value obtained by the establishment of the small part prize.
In addition, since the internal winning probability of the special winning is higher than the case of the RT1 state ST331 and the ART1 state ST341, there is a high possibility that the special winning will be established during the RT2 state ST332 or the ART2 state ST342. . In addition, since the winning probability of the RT end replay winning as a specific game end condition is lower than the RT1 state ST331 and the ART1 state ST341, there is a high possibility that the RT state will continue.
Further, since the internal winning probability of the small role winning other than the replay winning and the three-option bell winning is higher than that in the RT1 state ST331 and the ART1 state ST341, the RT2 state ST332 or the ART2 state 342 The possibility of winning a small role winning is increased. Furthermore, since the required bet number is 2, the net increase number (the number of payouts−the number of bets) when the small role winning is established increases. Therefore, in the RT2 state ST332 and the ART2 state ST342, it can be expected that a higher game value can be obtained compared to the RT1 state ST331 and the ART1 state ST341.
Further, in the ART2 state ST342, the type of the internally selected 3-option bell winning is notified, so that more game media can be obtained than in the RT2 state ST331.

  In the RT3 state ST333, an internal lottery is performed according to a winning determination table in which the internal winning probabilities of various winnings become the internal winning probabilities shown in FIG. That is, the internal winning probabilities of the special winning are set to “1/300” for the BB1 to BB3 winnings, “1/150” for the BB4 winnings, and “1/250” for the RB winnings, respectively. The combined probability of internally winning the BB prize is “1 / 60.0”, and the combined probability of internally winning the special prize is “1 / 48.4”. In addition, the internal winning probability of the small role winning is “1/15” for the 3 choice bell winning (same as in the RT1 state), “1/8” for the bell winning, “1/8” for the watermelon winning, cherry The winning is set to “1/85”, the replay winning is set to “1 / 2.8”, the RT end replay winning is set to “1/10”, and the ART start replay winning is set to “1/20”. Further, in the RT3 state ST333, the necessary bet number necessary for executing the game is fixed to 1.

  In the RT3 state ST333, when the ART start replay winning is established, the state shifts to the ART3 state ST343. On the other hand, as shown in FIG. 28, when any special game end condition is satisfied when the BB winning is won internally, when the RB winning is won internally, or when the RT end replay winning is established, the RT3 state ST333 is established. Is ended, and the state shifts to the normal gaming state ST30.

In ART3 state ST343, an internal lottery is performed according to a winning determination table in which the internal winning probabilities of various winnings become the internal winning probabilities shown in FIG. That is, the internal winning probability in the case of the RT3 state ST333 is inherited only by the ART start replay winning being excluded from the target of the internal lottery. Also, in the ART3 state ST343, the type of the 3-option bell winning that is won internally and the push order for avoiding the RT end replay winning are notified.
In the ART3 state ST343, as shown in FIG. 28, when the number of games executed reaches 30 games, the ART3 state ST343 ends, and the process proceeds to the RT3 state ST333. On the other hand, if any special game end condition is satisfied when the BB winning is won internally, when the RB winning is internally won, or when the RT end replay winning is established, the ART3 state ST343 is ended and the normal gaming state Move on to ST30. However, as long as the player follows the notified pressing order, the ART3 state ST343 will not be ended due to the establishment of the RT end replay winning.

In RT3 state ST333 and ART3 state ST343, similar to RT1 state ST331 etc., the internal winning probability of replay winning (replay winning, RT end replay winning, ART start replay winning combined probability) is compared with that in the normal gaming state ST30. Since the probability is high, it is possible to keep playing games while reducing the consumption of medals. Accordingly, it is possible to expect winning of the special prize while increasing the game value obtained by the establishment of the small part prize.
Further, since the internal winning probability of the special winning is higher than that in the case of the RT2 state ST332 and the ART2 state ST342, there is a high possibility that the special winning will be established during the RT3 state ST333 or the ART3 state ST343. . Further, since the winning probability of the RT end replay winning as a specific game end condition is lower than the RT2 state ST332 and the ART2 state ST342, the possibility that the RT state continues is further increased.
Further, since the internal winning probability of the small role winning other than the replay winning and the three-option bell winning is higher than that in the RT2 state ST332 and the ART2 state ST342, the RT3 state ST333 or the ART3 state 343 The possibility of winning a small role winning is further increased. Furthermore, since the required bet number is 1, the net increase number (the number of payouts−the number of bets) when the small role winning is established increases. Therefore, in the RT3 state ST333 and the ART3 state ST343, it can be expected that a higher game value can be obtained compared to the RT2 state ST332 and the ART2 state ST342.
Also, in the ART3 state ST343, the type of the three-choice bell winning that was won internally is notified, so that more game media can be acquired than in the RT3 state ST333.

  In the slot machine of the third embodiment, game control processing is performed in substantially the same manner as in the first embodiment. Part of the game end process is different from that of the first embodiment (see FIG. 13). In the third embodiment, the game end process is executed according to the flowcharts of FIGS.

  In step S401 in FIG. 39, it is determined whether the current gaming state is the RB state or the BB state based on the state flag indicating the gaming state. When it is determined that the current gaming state is the RB state or the BB state, the process proceeds to step S421 in FIG. 40, and when it is determined that the current gaming state is not the RB state or the BB state, the process proceeds to step S402.

In step S402, based on the determination result in the winning determination process (step S7 in FIG. 11), it is determined whether an RB winning or a BB winning is established. When it is determined that the RB winning or BB winning is established, the process proceeds to step S403, and when it is determined that the RB winning or BB winning is not established, the process proceeds to step S405.
In step S403, a state flag (bonus state flag) corresponding to the established special winning is set, and in step S404, the bonus winning flag is cleared.

In step S405, based on the set winning flag, it is determined whether or not a special replay winning has been established. If it is determined that the special replay winning has been established, the process proceeds to step S406 and the RT3 state flag is set. On the other hand, if it is determined that the special replay winning is not established, the process proceeds to step S407.
In step S407, based on the determination result in the winning determination process (step S7 in FIG. 11), it is determined whether or not the RT end replay winning is established. If it is determined that the RT end replay winning has been established, the process proceeds to step S408 to clear the RT state flag. On the other hand, if it is determined that the RT end replay winning is not established, the process proceeds to step S409.

In step S409, based on the determination result in the winning determination process (step S7 in FIG. 11), it is determined whether an ART start replay winning is established. If it is determined that the ART start replay winning is established, the process proceeds to step S410. If it is determined that the ART start replay winning is not established, the process proceeds to step S411.
In step S410, an ART state flag is set. At this time, the ART state flag corresponding to the current RT state is set based on the RT state flag. For example, when the RT1 status flag is set, the ART1 status flag is set, and when the RT2 status flag is set, the ART2 status flag is set.

  In step S411, the small role winning flag (including the special replay winning flag, the RT end replay winning flag, and the ART start replay winning flag) is cleared, and the process returns to the main process in FIG. If the RB winning or BB winning is not established even though the bonus winning flag is set, the bonus winning flag is not cleared and is carried over to the next game.

If it is determined in step 401 that the state is the RB state or the BB state, the total payout number paid out in the RB state or the BB state is acquired in step S421 in FIG. Specifically, the current payout number is added to the total payout number up to the previous time.
In step S422, the total payout number acquired in step S421 is compared with the specified number in the generated RB state or BB state (50 sheets in the RB state and 350 sheets in the BB state).
In step S423, based on the comparison result in step S422, it is determined whether or not the total payout number exceeds the specified number. If it is determined that the total payout number exceeds the specified number, the process proceeds to step S424. On the other hand, if it is determined that the total payout number does not exceed the prescribed number, the process proceeds to step S411 in FIG. 39 to clear the small role winning flag, and then returns to the main process in FIG.

In step S424, based on the bonus state flag, it is determined whether or not the special game state that has occurred is the BB1 state. If it is determined that the state is BB1, the process proceeds to step S425, and the RT1 state flag is set. On the other hand, if it is determined that the state is not BB1, the process proceeds to step S426.
In step S426, based on the bonus state flag, it is determined whether or not the special game state that has occurred is the BB2 state. If it is determined that the state is BB2, the process proceeds to step S427, and the RT2 state flag is set. On the other hand, if it is determined that the state is not BB2, the process proceeds to step S428.
In step S428, based on the bonus state flag, it is determined whether or not the special game state that has occurred is the BB3 state. If it is determined that the state is the BB3 state, the process proceeds to step S429, and the RT3 state flag is set. On the other hand, if it is determined that the state is not BB3, the process proceeds to step S430.
In step S430, the bonus state flag is cleared to end the special game state. In step S411 in FIG. 39, the small role winning flag is cleared, and then the process returns to the main process in FIG.

  In the internal lottery process, the winning determination table corresponding to the generated RT state is referenced based on the RT1 state flag set in step S425, the RT2 state flag set in step S427, and the RT3 state flag set in step S429. (Step S106 in FIG. 12). Further, during the ART state, the winning determination table corresponding to the generated ART state is referred to based on the ART state flag set in step S410.

As described above, in the third embodiment, the special game control means is based on establishment of a special game generation condition for generating a special game state (RT state) (special replay winning or internal winning of BB1 to BB3 winning) One of a plurality of special game states (RT1 state, RT2 state, RT3 state) having different winning probability for special winning in the internal lottery is selected and generated (steps S424 to S429 in FIG. 40).
Further, in a plurality of special game states, the probability of establishment of a special game end condition for ending this special game state (internal winning probability of RT end replay winning) is different.

According to the slot machine of the third embodiment, since the winning probability of the special winning in the special gaming state (RT state) is higher than that in the normal gaming state, the expected value when the special gaming state occurs (probably estimated) Acquisition number). On the other hand, in order to average machine discount, special game end conditions (internal winning probability of RT end replay winning) are set so that the average number of games executed in one special game state is shortened. There is little possibility that the player will be restrained for a long time due to the occurrence of the state.
Therefore, a slot machine having a new gaming property that can easily enjoy a game for a short time without restraining the player for a long time due to the occurrence of a special gaming state is realized.
In addition, since the internal winning probability of the RT end replay winning in the RT state that occurs in the BB state varies depending on the type of the BB state, it is possible to prevent the number of obtained coins from being biased depending on the player's skill, and provide fair game play can do.

In addition, the special game control means sets the probability of establishment of the special game end condition lower as the special game state has a higher probability of winning the special prize in the internal lottery (see FIGS. 33 to 35).
This realizes a new gameability in which the continuation rate of the special game state changes depending on the type of the special game state that occurs, so that the player's interest in the game can be enhanced.

Further, the special game control means sets the required bet number necessary for executing the game for each of a plurality of special game states (RT1 state, RT2 state, RT3 state). More specifically, the smaller the required bet number is set for the special game state having a higher probability of winning the special prize (RT1 state: bet number 3, RT2 state: bet number 2, RT3 state: bet number 1).
As a result, a new gameability is realized in which the net increase in number when the small role winning other than the replay winning is established in the special gaming state is changed depending on the type of the special gaming state to be generated. Can be increased.

Also, the special game control means determines the special game state to be generated according to the special prize type (BB1 to BB3 prize) won in the internal lottery. For example, when the BB1 winning is won internally, the RT1 state is generated after the BB1 state, and when the BB2 winning is internally won, the RT2 state is generated after the BB2 state.
As a result, the player becomes interested in the type of the special prize won internally, so that the player's interest in the game can be enhanced.

In the third embodiment, the RT generation pattern described in the first embodiment can also be applied. That is, in the third embodiment, when a special winning as a special game generation condition is established, any one of a plurality of special game states may be selected and generated.
As a result, a large amount of game media can be obtained with the establishment of the special prize, and a special game state advantageous to the player is generated, and the player's gambling feeling is moderately given. Can be increased.

Further, in the third embodiment, when an internal winning is made in a special winning that is a special game occurrence condition during the special gaming state (RT state), the special game has a higher winning probability of the special winning than the winning probability in the special gaming state. A state may be generated.
Thus, whenever a special prize that is a special game occurrence condition is established during the special game state, the player is promoted to a game state advantageous to the player, so that the player's sense of expectation for the special game state can be further enhanced.

In the third embodiment, the special game having the lowest winning probability of the special winning when the special winning that becomes the special game occurrence condition is internally won in the special gaming state (RT3 state) having the highest winning probability of the special winning. A state (RT1 state) may be generated.
As a result, the special gaming state that is most advantageous for the player will not occur continuously, so that the gambling ability of the gaming machine is suppressed, and the player's gambling feeling is excessively beaten due to the biased medal. Can be prevented.

Furthermore, in the third embodiment, when a special winning that is a special game occurrence condition is won internally in the special gaming state, and the number of continuations of the special gaming state reaches a predetermined number, the special winning with the lowest winning probability of the special winning is achieved. A gaming state (RT1 state) may be generated.
Thereby, since a medal can be suppressed when the special gaming state is continuously generated many times, the gambling ability of the gaming machine is suppressed, and the player's gambling feeling can be prevented from being excessively beaten.

  In addition, when the special replay winning is selected in the RT state internal lottery and the special replay winning is established during the RT state, the special replay winning is performed after the running RT state is ended by the establishment of the special game end condition. A new RT state may be generated in accordance with the establishment of (so-called RT state stock). Further, the RT state may be ended with a predetermined number of games (for example, 100 games).

  Furthermore, in a plurality of RT states, it is possible to set the internal winning probabilities of RT end replay winnings to be the same, and to set the probabilities of establishing RT end replay winnings to be different. For example, the establishment of the RT end replay winning is avoided when the correct answer is selected in the 6-selection push order. The RT1 state has one type of push order that is correct (5/6 ends RT), and the RT2 state has two types (4 RT ends at / 6) and three types in RT3 state (RT ends at 3/6).

[Fourth Embodiment]
The slot machine of the fourth embodiment has almost the same configuration as the slot machine 1 of the first embodiment. Here, points different from the slot machine 1 of the first embodiment will be mainly described. In the fourth embodiment, when a special prize that is a special game occurrence condition is established during the RT state, the player enters an RT state that is advantageous to the player.

  FIG. 41 is a diagram showing the types of winnings in the slot machine of the fourth embodiment, symbol combination modes corresponding to the winnings and winning contents, and FIG. 42 is a diagram showing the special game state and the special game state end conditions. . Since the RB winning, the Bell winning, the watermelon winning, the cherry winning, and the replay winning are the same as those in the first embodiment, the description thereof is omitted.

As shown in FIG. 41, as in the first embodiment, a black 7BB winning and a white 7BB winning are provided as BB winnings. However, in the fourth embodiment, a special gaming state that occurs after the black 7BB state ends. It is fixed in the RT1 state. Further, even when a special replay winning is established, the special game state to be generated is fixed to the RT1 state.
The RT state generated when the black 7BB winning is established or when the special replay winning is established is not fixed to the RT1 state, and may be determined by lottery from a plurality of RT states.

  The RT2 start replay winning is a winning that is established when the symbol combination aspect of “replay-replay-replay” is formed on the upper effective line. RT2 start replay winnings are subject to internal lottery only in the RT1 state. When the RT2 start replay winning is won internally, the symbol combination mode of “Replay-Replay-Replay” is always formed on the upper effective line by the reel stop control. When the RT2 start replay winning is established, a replay game is given and an RT2 state is generated.

  The RT3 start replay winning is a winning that is established when the symbol combination aspect of “replay-replay-replay” is formed on the lower effective line. The RT3 start replay winning is subject to internal lottery only in the RT2 state. When the RT3 start replay winning is won internally, the symbol combination mode of “replay-replay-replay” is always formed on the middle effective line by the reel stop control. When the RT3 start replay winning is established, a replay game is given and an RT3 state is generated.

FIG. 43 is a state transition diagram for explaining a gaming state in the slot machine of the fourth embodiment. In the slot machine of the fourth embodiment, it is assumed that the game is started in the normal gaming state ST40 immediately after the power is turned on.
Since the normal gaming state ST40 and the RB state ST41 are the same as those in the first embodiment, description thereof will be omitted. In the normal gaming state ST40, an internal lottery is performed in accordance with a winning determination table having internal winning probabilities shown in FIG. However, in the normal gaming state ST40, the RT2 start replay winning and the RT3 start replay winning are not subject to the internal lottery, and thus are substantially the same as those in the first embodiment (see FIG. 7).

  In the BB state ST42, for example, a game is executed in which the internal winning probability of the small prize winning is higher than that in the normal gaming state. When the total number of medals paid out to the player exceeds 350, the BB state ST42 ends. And after BB state ST42 is complete | finished, it transfers to RT1 state ST43.

  In the RT1 state ST43, an internal lottery is performed according to a winning determination table in which the internal winning probabilities of various winnings become the internal winning probabilities shown in FIG. That is, the internal winning probabilities for the special prize, the bell prize, the watermelon prize, and the cherry prize are the same as those in the normal game state ST40, the replay prize is "1 / 1.5", and the RT2 start replay prize is "1/20". Is set. Further, in the RT1 state ST43, the necessary bet number necessary for executing the game is fixed to 3.

In the RT1 state ST43, when the RT2 start replay winning is established, the state shifts to the RT2 state. On the other hand, as shown in FIG. 42, when the number of executed games reaches 50 games, when BB winning is won internally, or when any special game end condition is met when RB winning is won internally RT1 state ST43 ends, and the normal game state ST40 is entered.
In the RT1 state ST43, when the black 7BB winning is established, the RT1 state is newly generated after the black 7BB state. The same applies to the RT2 state ST44 and the RT3 state ST45.

  In the RT1 state ST43, since the internal winning probability of the replay winning is higher than that in the normal gaming state ST40, it is possible to overlap the game while suppressing the consumption amount of medals. Accordingly, it is possible to expect winning of the special prize while increasing the game value obtained by the establishment of the small part prize.

  In the RT2 state ST44, an internal lottery is performed according to a winning determination table in which the internal winning probabilities of various winnings become the internal winning probabilities shown in FIG. That is, the internal winning probability of the special prize is set to “1/180” for the black 7BB prize, “1/280” for the white 7BB prize, and “1/400” for the RB prize. The combined probability of internally winning the BB prize is “1 / 109.6”, and the combined probability of internally winning the special prize is “1 / 86.6”. In addition, the internal winning probability of the small role winning is as follows: Bell winning 1/9, Watermelon winning 1/9, Cherry winning 1/100, Replay winning 1 / 1.5, RT3 The start replay winning is set to “1/20”. The internal lottery probability of the RT3 start replay winning is set to be the same as the internal winning probability of the RT2 starting replay winning, but may be set differently. Further, in the RT2 state ST332, the necessary bet number necessary for executing the game is fixed to 2.

  In the RT2 state ST44, when the RT3 start replay winning is established, the state shifts to the RT3 state. On the other hand, as shown in FIG. 42, when the number of executed games reaches 50 games, when BB winning is won internally, or when any special game end condition is met when RB winning is won internally The RT2 state ST44 ends, and the normal game state ST40 is entered.

In the RT2 state ST44, as in the RT1 state ST43, the internal winning probability of the replay winning is higher than that in the normal gaming state ST40, so that the game can be repeated while suppressing the consumption of medals. It becomes possible. Accordingly, it is possible to expect winning of the special prize while increasing the game value obtained by the establishment of the small part prize.
Further, since the internal winning probability of the special prize is higher than that in the RT1 state ST43, the possibility that the special prize is established during the RT2 state ST44 is increased.
Further, since the internal winning probability of the small role winning other than the replay winning is higher than that in the RT1 state ST43, there is a high possibility that the small role winning is established during the RT2 state ST44. Furthermore, since the required bet number is 2, the net increase number (the number of payouts−the number of bets) when the small role winning is established increases. Therefore, it can be expected that a higher gaming value is obtained in the RT2 state ST44 than in the RT1 state ST43.

  In the RT3 state ST45, an internal lottery is performed according to a winning determination table in which the internal winning probabilities of various winnings become the internal winning probabilities shown in FIG. That is, the internal winning probability of the special winning is set to “1/100” for the black 7BB winning, “1/150” for the white 7BB winning, and “1/250” for the RB winning. The combined probability of internally winning the BB prize is “1 / 60.0”, and the combined probability of internally winning the special prize is “1 / 48.4”. In addition, the internal winning probability for small role winning is set to "1/8" for Bell winning, "1/8" for watermelon winning, "1/85" for cherry winning, and "1 / 1.5" for replay winning Has been. Further, in the RT3 state ST45, the necessary bet number necessary for executing the game is fixed to 1.

  In the RT3 state ST45, as shown in FIG. 42, when the number of executed games reaches 50 games, when the BB winning is won internally, or when the RB winning is won internally, any special game end condition is If established, the RT3 state ST45 is ended, and the state shifts to the normal gaming state ST40.

In the RT3 state ST45, as in the RT1 state ST43 and the RT2 state ST44, the internal winning probability of the replay winning is higher than that in the normal gaming state ST10. Can be stacked. Accordingly, it is possible to expect winning of the special prize while increasing the game value obtained by the establishment of the small part prize.
Further, since the internal winning probability of the special winning is higher than that in the RT2 state ST44, the possibility that the special winning is established during the RT3 state ST45 is further increased.
In addition, since the internal winning probability of the small part winning other than the replay winning is higher than that in the RT2 state ST44, the possibility that the small part winning is established during the RT3 state ST45 is further increased. Furthermore, since the required bet number is 1, the net increase number (the number of payouts−the number of bets) when the small role winning is established increases. Therefore, in the RT3 state ST45, it can be expected that a higher game value can be obtained compared to the RT1 state ST43 and the RT2 state ST44.

  In the slot machine of the fourth embodiment, game control processing is performed in substantially the same manner as in the first embodiment. Part of the game end process is different from the first embodiment (see FIG. 13). In the fourth embodiment, the game end process is executed according to the flowcharts of FIGS.

  In step S501 of FIG. 48, it is determined whether the current gaming state is the RB state or the BB state based on the state flag indicating the gaming state. When it is determined that the current gaming state is the RB state or the BB state, the process proceeds to step S521 in FIG. 49, and when it is determined that the current gaming state is not the RB state or the BB state, the process proceeds to step S502.

In step S502, based on the determination result in the winning determination process (step S7 in FIG. 11), it is determined whether an RB winning or a BB winning is established. If it is determined that the RB winning or BB winning is established, the process proceeds to step S503. If it is determined that the RB winning or BB winning is not established, the process proceeds to step S505.
In step S503, a state flag (bonus state flag) corresponding to the established special winning is set, and in step S504, the bonus winning flag is cleared.

In step S505, it is determined whether or not a special replay winning has been established based on the set winning flag. If it is determined that the special replay winning has been established, the process proceeds to step S506. If it is determined that the special replay winning is not established, the process proceeds to step S508.
In step S506, the RT1 state flag is set, and in step S507, “50” is set as an initial value in the RT number counter.
In step S508, it is determined based on the set winning flag whether or not the RT2 start replay winning has been established. If it is determined that the RT2 start replay winning is established, the process proceeds to step S509. If it is determined that the RT2 starting replay winning is not established, the process proceeds to step S511.
In step S509, the RT2 state flag is set, and in step S510, "50" is set as an initial value in the RT number counter.
In step S511, based on the set winning flag, it is determined whether or not RT3 start replay winning has been established. If it is determined that the RT3 start replay winning is established, the process proceeds to step S512. If it is determined that the RT3 start replay winning is not established, the process proceeds to step S514.
In step S512, the RT3 status flag is set, and in step S513, “50” is set as an initial value in the RT number counter.

  In step S514, the small role winning flag (including the special replay winning flag, the RT2 start replay winning flag, and the RT3 start replay winning flag) is cleared, and the process returns to the main process in FIG. If the RB winning or BB winning is not established even though the bonus winning flag is set, the bonus winning flag is not cleared and is carried over to the next game.

When it is determined in step 501 that the state is the RB state or the BB state, the total payout number paid out in the RB state or the BB state is acquired in step S521 in FIG. Specifically, the current payout number is added to the total payout number up to the previous time.
In step S522, the total payout number acquired in step S521 is compared with the specified number in the generated RB state or BB state (50 sheets in the RB state and 350 sheets in the BB state).
In step S523, based on the comparison result in step S522, it is determined whether or not the total payout number exceeds the specified number. If it is determined that the total payout number exceeds the specified number, the process proceeds to step S524. On the other hand, if it is determined that the total payout number does not exceed the prescribed number, the process shifts to step S514 in FIG. 48 to clear the small role winning flag, and then returns to the main process in FIG.

In step S524, based on the bonus state flag, it is determined whether or not the special gaming state that has occurred is a black 7BB state. If it is determined that the state is the black 7BB state, the process proceeds to step S525. If it is determined that the state is not the black 7BB state, the process proceeds to step S527.
In step S525, the RT1 status flag is set, and in step S526, “50” is set as an initial value in the RT number counter.
In step S527, the bonus state flag is cleared to end the special game state. In step S514 of FIG. 49, the small role winning flag is cleared, and then the process returns to the main process of FIG.

  In the internal lottery process, the winning determination corresponding to the generated RT state is based on the RT1 state flag set in step S506 or step S527, the RT2 state flag set in step S509, and the RT3 state flag set in step S512. The table is referred to (step S106 in FIG. 12).

  As described above, in the fourth embodiment, the special game control means is configured such that when a special prize (RT2 start replay prize or RT3 start replay prize) is established during the special game state (RT1 state or RT2 state) Any one of a plurality of special game states (RT1 state, RT2 state, RT3 state) having different winning probabilities in the lottery is selected and generated.

According to the slot machine of the fourth embodiment, the winning probability of the special winning in the special gaming state (RT state) is higher than that in the normal gaming state, so the expected value when the special gaming state occurs (probably estimated) Acquisition number). On the other hand, special game end conditions (for example, the prescribed number of games in the RT state) are set so that the average number of games executed in one special game state is shortened in order to average machine discounts. There is little possibility that the player will be restrained for a long time due to the occurrence of the state.
Therefore, a slot machine having a new gaming property that can easily enjoy a game for a short time without restraining the player for a long time due to the occurrence of a special gaming state is realized.

Further, the special game control means sets the required bet number necessary for executing the game for each of a plurality of special game states (RT1 state, RT2 state, RT3 state). More specifically, the smaller the required bet number is set for the special game state having a higher probability of winning the special prize (RT1 state: bet number 3, RT2 state: bet number 2, RT3 state: bet number 1).
As a result, a new gameability is realized in which the net increase in number when the small role winning other than the replay winning is established in the special gaming state is changed depending on the type of the special gaming state to be generated. Can be increased.

Further, the special game control means generates a special game state in which the winning probability of the special winning is higher than the winning probability in the special game state.
Thus, whenever a special prize (RT2 start replay prize or RT3 start replay prize) that is a special game occurrence condition is established during the special game state, the player is promoted to a game state advantageous to the player. The expectation for can be further increased.

  Further, in the RT1 to RT3 states, special replay winning, RT2 start replay winning, or RT3 replay winning may be targeted for internal lottery so that the RT state can be continuously generated.

As mentioned above, although the invention made by this inventor was concretely demonstrated based on embodiment, this invention is not limited to the said embodiment, It can change in the range which does not deviate from the summary.
For example, in the first to fourth embodiments, when the RT state occurs due to the establishment of the special replay winning, an effect that delays the start of fluctuation of the reel 6 for a predetermined period (so-called freeze effect) may be performed. .
In this case, as shown in FIG. 50, when the special replay winning is internally won based on the operation of the star and lever 21, the start of fluctuation of the reel 6 is delayed for a predetermined period, and the operation of the reel stop button 24 is also impossible during this period. Become. In addition, in the image display device 3, a flashy effect display is performed that suggests that the player has won the special replay prize. When the game ends, a special replay winning is established, and an RT state is generated from the next game. Moreover, with the establishment of the special replay winning, the image display device 3 performs an effect display that suggests that the RT state occurs.

Thereby, since it can be notified by a flashy effect that the RT state occurs due to the establishment of the special replay winning, the satisfaction of the player can be enhanced.
In the fourth embodiment, the above-described freeze effect may be performed not only when the special replay prize is won internally but also when the RT2 start replay prize or RT3 start replay prize is won internally.

In addition, the contents that are set differently in a plurality of RT states include the internal winning probability of the special winning, the required bet number necessary for executing the game, the internal winning probability of the small winning, the number of payouts when the small winning is established, Any one of the establishment probabilities of the special game end condition or a combination thereof can be applied.
Further, the contents described in the first to fourth embodiments can be applied in appropriate combination.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
