The embodiment of the present invention will be specifically described with reference to the following examples.
(Example 1)
This example relates to a slot machine 1 that can generate an RT state (special state) having a high internal winning probability of a replay combination and a higher degree of advantage than the normal state. The contents will be described with reference to FIGS.

  First, the external configuration of the slot machine 1 of this example will be described with reference to FIG. In the slot machine 1, the front portion facing the player is formed by a front frame body 10 having a substantially rectangular symbol display window 11 provided substantially at the center. The front frame 10 is configured by arranging a liquid crystal display unit 53, a pair of left and right speakers 520, and a decorative lamp unit 56 on the upper side of the symbol display window 11. A bottom portion 100 that forms the base of the slot machine 1 is formed below the symbol display window 11. On the right side of the symbol display window 11, a payout number display unit 551 for displaying the number of medal payouts and a credit number display unit 552 for displaying the number of credits are arranged.

  The base portion 100 is formed so as to protrude relatively with respect to the symbol display window 11 located behind the player. The base portion 100 has a table-like operation surface 14 at the upper end adjacent to the symbol display window 11, and has a medal tray 15 at the lower end for paying out medals (game media). An operation panel 13 is provided between the tray 15 and the tray 15.

  On the operation surface 14, a bet button 64 for inserting a medal credited (stored) by a credit function, a settlement button 65 for paying out a credited medal, and a medal insertion for directly inserting a medal A mouth 630 is arranged. The operation panel 13 includes a start lever 62 (game start operation means) for starting the symbol fluctuation of the reel 21, a stop button 61 (stop operation means) for stopping the symbol fluctuation, and occurrence of an RT state. Therefore, an RT button 69 (special state generating operation means) operated by the player is arranged.

  The bet button 64 is a button for inserting three medals out of the credited medals. The bet button 64 generates a 3-bet signal indicating the insertion number 3. However, when the remaining credit is 2 or 1, a 2-bet signal or 1-bet signal is generated, and when the credit is zero, a bet signal is not generated.

  The start lever 62 is an operation lever that generates a game start signal that is a control signal for the reel 21 in accordance with the player's operation. In the slot machine 1, the start lever 62 is set to the valid state on the premise that a medal is inserted directly or a medal is inserted by operating the bet button 64. When the replay winning combination is won, a state is set in which a medal is directly inserted or a medal is automatically inserted without a betting operation, that is, a state where the next game can be started.

  The stop button 61 is an operation button that generates a variable stop signal that is a control signal for the reel 21 in accordance with the player's operation. The stop button 61 of this example is a combination of a left stop button 61L corresponding to the left reel 21L, a middle stop button 61C corresponding to the middle reel 21C, and a right stop button 61R corresponding to the right reel 21R.

  The RT button 69 is an operation button for the player to perform an operation related to the RT state. According to the RT button 69, it is possible to perform operations such as generating an RT state according to the player's own will and ending the generated RT state. The RT button 69 of this example has a function as a special state generation operation unit and a function as a special state end operation unit.

  As shown in FIG. 1, the symbol display window 11 is a display window including symbol display areas 110L, C, and R. Each of the symbol display areas 110L, C, and R is a symbol display area for three symbols. In the entire symbol display window 11, symbol display regions for nine symbols arranged in a two-dimensional matrix composed of three rows and three columns are formed. The entire symbol display window 11 is formed of a transparent resin plate so that the symbol 20 can be seen from the player side. For the nine symbols 20 arranged in a two-dimensional matrix, winning lines 211 to 215 that are the arrangement direction of winning symbols to be awarded are set. As the winning lines, there are horizontal winning lines 211 to 213 and diagonal winning lines 214 and 215.

  Reels 21L, C, and R constituting the symbol variation display means 2 are arranged on the back side of the symbol display areas 110L, C, and R, respectively. The reels 21L, C, and R are rotary reels having a cylindrical shape and 21 symbols 20 as shown in FIG. 2 arranged at substantially constant intervals on the outer peripheral surface thereof. The reel 21 may be an image-type reel that displays the symbols on the liquid crystal display in place of the rotary reel of this example.

  As shown in FIG. 1, the speaker 520 and the decorative lamp unit 56 are rendering means for rendering a game with sound or light. The payout number display unit 551 is a display unit that displays the number of medals paid out at the time of winning a prize. The credit number display unit 552 is a display unit that displays the number of medals credited (stored) by the credit function.

  The liquid crystal display unit 53 includes a liquid crystal display. The liquid crystal display unit 53 displays various effect screens for effecting a game in addition to a BIG bonus medium screen 710 (FIG. 7), an RT standby state screen 720 (FIG. 8), and an RT state screen 730 (FIG. 9), which will be described later. It can be displayed.

  Next, the combination of the slot machine 1 of this example, the internal winning combination, and the winning combination will be described, and the outline of the game will be described. In the slot machine 1, as shown in FIG. 3, there are two types of BIG bonus combination (BIG1, BIG2), one type of REG bonus combination (REG), 15 sheet combination, 10 sheet combination, 5 sheet combination, 2 sheet combination, etc. Four types of small combinations and replay combinations are set. In FIG. 3, the name of each combination is shown in the left column, a winning symbol that is a combination of symbols 20 corresponding to each combination is shown in the middle column, and the profit given to the player according to the winning is shown in the right column. In the slot machine 1, the winning combination internally by the internal lottery means 41 described later becomes the internal winning combination. When the winning symbol corresponding to the internal winning combination is established along the winning line, the winning combination becomes the winning combination.

  In the game of the slot machine 1 of this example, the BIG bonus state, the REG bonus state, the RT state (special state), and the normal state can be selectively generated. Furthermore, in the normal state, a standby state that can generate the RT state according to the operation of the RT button 69 may occur repeatedly.

  The BIG bonus state is the most advantageous gaming state that occurs in response to winning of BIG1 and BIG2, and ends when the number of medals paid out exceeds 360. The REG bonus state is an advantageous gaming state that occurs in response to a REG winning and ends when the number of medals paid out exceeds 150. The RT state is an advantageous gaming state in which the internal winning probability of the replay combination is higher than the normal state. In the slot machine 1, the BIG in-progress flag corresponding to the BIG bonus state and the RT flag corresponding to the RT state are set as control flags.

  In the BIG bonus state, a special state generation right, which is a right that can generate the RT state, is awarded in accordance with a winning combination (predetermined condition) of 15 sheets. Specifically, during the occurrence of the BIG bonus state, an acquisition lottery for determining the number of RT games, which is the number of games generated in the RT state, is executed in accordance with the 15-game winning combination, and the determined number of RT games Can be sequentially added as the cumulative number of RT games (the cumulative number of generated games).

In the normal state, a standby state may occur when the right to generate a special state is generated, that is, when the cumulative number of RT games is one or more games. In this standby state, an artificial game such as generating an RT state in response to the operation of the RT button 69 becomes possible.
While the RT state is occurring, the RT state can be terminated by operating the RT button 69 to return to the standby state.
Further, in the game of the slot machine 1 of this example, when the generation operation by the RT button 69 is performed, an advantage based on the special state generation right, that is, a chance to increase the cumulative number of RT games is set.

  Next, the electrical configuration of the slot machine 1 of this example will be described with reference to FIG. For the control unit 3 that controls the overall operation of the slot machine 1, in addition to the above-described configuration, the inserted medal detection unit 63 that detects medals inserted directly through the medal insertion slot 630 and the reel 21 together with the symbol variation display Various display units including a reel driving unit 22 constituting the means 2, a reference position detecting unit 66 for detecting the rotational position of the reel 21, a medal paying unit 54 for paying out medals, a payout number display unit 551 and a credit number display unit 552. 55, a set value operation unit 68 for setting a set value representing the player's degree of advantage, an audio output unit 52 for controlling the speaker 520, and the like are electrically connected.

  The inserted medal detection unit 63 is a detection unit for a medal inserted directly from the medal insertion port 630. The inserted medal detection unit 63 outputs an insert signal every time a medal is inserted from the medal insertion slot 630. In the slot machine 1 of this example, when three medals are inserted by direct insertion of medals or operation of the bet button 64, the start lever 62 is set to an effective state and a new game can be started. It becomes a state.

  The reel driving unit 22 includes a stepping motor (not shown) that can be controlled in units of steps, and is means for rotating the reel 21 by the rotational driving force of the stepping motor. The reference position detection unit 66 is a detection unit that detects the passage of the reference position piece for each of the reels 21L, 21C, and R and outputs a detection signal.

The medal payout unit 54 is a payout unit that pays out to the medal tray 15 the number of medals (see FIG. 3) corresponding to the winning combination determined by the winning determination means 44 described later. For example, when 15 winning combinations are winning combinations, 15 medals are paid out.
The set value operation unit 68 is an operation unit for changing set values of 6 stages having different winning probabilities such as bonus combinations using the setting key 680.

  As shown in FIG. 4, the control unit 3 extracts a CPU 31, a ROM 33 and a RAM 34 as memory means, an I / O 32 as an input / output interface, a random number generator 350 for generating random numbers, and a random number for lottery. And a random number extraction unit 35. The CPU 31 executes a software program read from the ROM 33, thereby executing an internal lottery means 41 for lottering an internal winning combination, a flag control means 42 for controlling an internal winning flag corresponding to the internal winning combination, and a display control for controlling the reel 21. Means 43, winning determination means 44 for determining a winning symbol, profit giving means 45 for giving a player a profit according to the winning, special state generating means for generating an RT state (special state) having a high internal winning probability of the replay role 46. Generating right granting means 47 for granting a player a special state generating right necessary for generating the RT state, standby state generating means 48 for generating a standby state capable of generating the RT state, and advantages of the special state generating right Each function as the right state increasing / decreasing means 49 for executing the right increasing / decreasing lottery for determining the increasing / decreasing degree is implemented. To.

  An RT counter 341 for storing the accumulated RT game number is set in a storage area of the RAM 34 which is a memory means. The accumulated number of RT games stored in the RT counter 341 is decremented by one game every time the game is consumed under the RT state. The cumulative number of RT games indicates the total amount of advantage based on the special state occurrence right acquired by the player.

  The ROM 33, which is a memory means, determines an internal winning combination lottery table (not shown) used for lottery of an internal winning combination, a reel control table (not shown) used by the display control means 43 for stop control of the reel 21, and the number of RT games. The RT game number acquisition lottery table (FIG. 5) used for the acquisition lottery to perform and the cumulative RT game number increase / decrease lottery table (FIG. 6) used for the right increase / decrease lottery are stored.

The reel control table is a table that defines a stop position at which a stop can be made on the winning line.
The internal winning combination lottery table is a data table in which the range of the winning random number of each combination is defined among the random numbers for lottery from 0 to 65535. The internal winning combination lottery table includes a table applied to the normal state, a table applied to the bonus state, and a table applied to the RT state. In particular, the table applied to the RT state is an internal winning combination lottery table in which most of the lost random numbers in the table for the normal state are replaced with the winning random numbers for the replay combination.

  As shown in FIG. 5, the RT game number acquisition lottery table is a data table in which winning random numbers of five types of RT games including zero games are specified from among random numbers for lottery of 0 to 127, respectively. For example, the lost random number corresponding to the case where the number of RT games is zero, that is, the special state occurrence right is not granted, is 0 to 12. The winning random number for only 100 RT games is 127. Therefore, in the acquisition lottery using this RT game number acquisition lottery table, RT game number = zero can be won with a probability of 13/128, and RT game number = 100 games can be won with a probability of 1/128. .

  As shown in FIG. 6, the cumulative RT game number increase / decrease lottery table is a data table in which a winning random number corresponding to “winning” and a lost random number corresponding to “non-winning” among the random numbers for lottery of 0 to 127 are defined. It is. As can be seen from the figure, the number of winning random numbers and the number of lost random numbers are both 64. Therefore, in the right increase / decrease lottery using this cumulative RT game number increase / decrease lottery table, the probability of “winning” and “non-winning” is halved.

As shown in FIG. 4, the random number generator 350 is a part that generates random numbers belonging to a predetermined integer range. The random number generator 350 generates a random number in the integer range of 0 to 65535 for drawing the internal winning combination and a random number in the integer range of 0 to 127 for the acquisition lottery and right increase / decrease lottery.
The random number extraction unit 35 is a part that extracts various random numbers for lottery. The random number extraction unit 35 extracts a random number for lottery for drawing an internal winning combination in response to a game start signal corresponding to the operation of the start lever 62. Also, a random number for lottery for the winning lottery is extracted according to the winning of 15 winning combinations in the BIG bonus state, and the right increase / decrease according to the operation of the RT button 69 in the game in which the 2 winning combinations are won internally. Extract random numbers for lottery for lottery.

  The internal lottery means 41 is a means for determining an internal winning combination by internal lottery and establishing an internal winning flag corresponding to the internal winning combination. The internal lottery means 41 collates the lottery random numbers against the winning random numbers of each combination specified in the internal winning combination lottery table, and determines the internal winning combination. The internal lottery means 41 selectively refers to the internal winning combination lottery table that matches the gaming state according to the flag state such as the BIG flag and the RT flag.

  The flag control means 42 is a means for controlling an internal winning flag corresponding to the internal winning combination. Regarding the internal winning flags of other combinations other than the bonus combination (BIG1, BIG2, REG), it is off until the next game is started regardless of whether or not a winning is won in the game in which the internal winning flag is established for the first time ( Reset to zero). Therefore, if each combination other than the bonus combination is not won in the internal winning game, all will be missed. On the other hand, regarding the internal winning flag corresponding to the bonus combination, the established state of the internal winning flag is sequentially carried over to the next game until winning, and is reset to the off state in accordance with winning.

  The display control means 43 is a means for executing so-called pull-in control in which symbols within a predetermined pull-in range determined by rules (rules for game machine authorization, type verification, etc.) are stopped on the winning line. In this example, as described above, a range corresponding to four symbols is set as the pull-in range. The display control means 43 collates the number of steps when the variable stop signal is taken in with the reel control table, and determines the stop position. The display control means 43 pulls the symbol corresponding to the determined stop position and stops the reel 21.

  The winning determination unit 44 is a unit that determines whether or not a winning has occurred based on a combination of symbols that the three reels 21L, 21C, 21R stop display. Specifically, the winning determination means 44 determines the winning combination according to the combination of symbols stopped on the winning lines 211 to 215 set so as to cross the three reels 21L, 21C, 21R. The winning determination means 44 takes in the number of steps of each stepping motor (reel driving unit 22) corresponding to each reel 21L, C, R after each reel 21L, C, R stops. The winning determination means 44 obtains the type of the symbol 20 stopped on the winning lines 211 to 215 based on the number of steps, and determines whether or not a winning combination is established for the combination of the symbols 20.

  The profit giving means 45 is a means for giving a profit corresponding to the winning combination determined by the winning determination means 44. For example, in the case where BIG1 and BIG2 which are bonus combinations are winning combinations, the profit granting means 45 gives a profit that the BIG bonus state is generated. If the winning combination is 5 prizes, a profit of paying out 5 medals is given.

  The generated right granting unit 47 is a unit that grants a special state generating right to the player in response to establishment of a predetermined condition. In this example, 15 winning combinations during the occurrence of the BIG bonus state are set as the predetermined condition. The generated right granting means 47 executes an acquisition lottery for determining the number of RT games, which is the number of generated games in the RT state, when granting the special state generated right.

The generation right giving means 47 determines the number of RT games by checking the lottery random number against the RT game number acquisition lottery table (FIG. 5). The number of RT games is the number of games that can be executed under the RT state in accordance with the establishment of a predetermined condition of winning 15 combinations. That is, the value of the number of RT games represents the degree of advantage of the special state occurrence right. When the number of RT games is determined to be zero, the special state generation right is zero, that is, the special state generation right is not granted. The greater the number of RT games that are selected, the greater the number of games generated in the RT state, and the higher the advantage based on the special state occurrence right.

  The generated right granting unit 47 adds to the accumulated RT game number stored in the RT counter 341 (FIG. 4) every time the RT game number is determined by the acquisition lottery. As a result, the special state occurrence right acquired by the player is stored as the cumulative number of RT games. In this example, the cumulative number of RT games is accumulated with 500 games as the upper limit.

  The standby state generating unit 48 is a unit that generates a standby state in which an RT state can be generated by operating the RT button 69. In the slot machine 1 of the present example, an RT generation possible flag is set as a control flag corresponding to the standby state. The standby state generating means 48 sets the RT occurrence flag to the on state when the normal state and the cumulative number of RT games stored in the RT counter 341 is one or more games, thereby generating a standby state. . On the other hand, when the BIG bonus state or the RT state is generated, and when the cumulative number of RT games is zero, the RT occurrence flag is set to the off state.

  The special state generating means 46 is means for generating an RT state (special state). The special state generating means 46 sets the RT flag to the on state in response to the operation of the RT button 69 in the standby state, thereby generating the RT state. When the RT button 69 is operated during the generation of the RT state, the RT state is terminated by resetting the RT flag to generate the normal state. At this time, if the cumulative number of RT games is one or more, it is possible to return to the standby state.

  The special state occurrence right increasing / decreasing means 49 is means for determining an increase / decrease in the degree of advantage based on the special state generating right by the right increase / decrease lottery. Here, in this example, the value of the cumulative number of RT games indicates the degree of advantage of the special state occurrence right acquired by the player. The special state occurrence right increasing / decreasing means 49 executes a right increasing / decreasing lottery when two winning combinations are won in a game in which an RT state has occurred by operating the RT button 69.

  Specifically, the special state occurrence right increasing / decreasing means 49 of this example executes a right increasing / decreasing lottery by collating a random number for lottery against the cumulative RT game number increasing / decreasing lottery table (FIG. 6). When “winning” is determined by the right increase / decrease lottery, the number of games corresponding to half of the cumulative number of RT games is added to the cumulative number of RT games. When “non-winning” is determined by a right increase / decrease lottery, the number of games corresponding to half of the cumulative number of RT games is subtracted from the cumulative number of RT games. In this example, when the cumulative number of RT games is one game, the right increase / decrease lottery is not executed even if two winning combinations win.

  Next, the contents of the effect screen displayed on the liquid crystal display unit 53 will be described with reference to FIGS. FIG. 7 shows a BIG bonus screen 710 that is displayed during the occurrence of the BIG bonus state. FIG. 8 shows an RT standby state screen 720 displayed in the standby state. FIG. 9 shows an RT status screen 730 that is displayed during the occurrence of the RT status.

  The BIG bonus in-progress screen 710 shown in FIG. 7 includes a status display field 710a for indicating that the BIG bonus status is occurring, a flag notification field 710b for notifying the internal winning of 15 sheets, and an RT for displaying the accumulated RT game number. It is a screen including the game number indicator 710c. The RT game number indicator 710c has ten scales for every 10 games, and can display the cumulative number of games from 0 to about 100 games in units of 10 games. The BIG in-progress screen 710 in the figure illustrates that 15 winning combinations are internally won during the occurrence of the BIG bonus state, and that the cumulative number of RT games is 70 games.

  The display of the RT game number indicator 710c can be canceled by operating the RT button 69. This specification is a specification for responding to a player who wants to enjoy the BIG bonus state without looking at the accumulated RT game number and check the accumulated RT game number accumulated after the end of the BIG bonus state. In this example, an indicator display flag that is a display control flag corresponding to the display state of the RT game number indicator 710c is set. The indicator display flag is set to the on state when the BIG bonus state is generated, and is reset according to the operation of the RT button 69. If the RT button 69 is operated again, the indicator display flag can be returned to the on state, and the display of the RT game number indicator 710c can be resumed.

  The RT standby state screen 720 shown in FIG. 8 displays the cumulative RT game number in the same manner as the flag notification column 720a and the RT game number indicator 710c for notifying the internal winning of the double winning combination, which is a necessary condition for the right increase / decrease lottery. This is a screen including an RT game number indicator 720b. The RT standby state screen 720 shown in the figure exemplifies that two winning combinations have been internally won in the standby state. In the state where the RT standby state screen 720 of FIG. 10 is displayed, there is a chance that the cumulative number of RT games can be increased in accordance with the operation of generating the RT state by the RT button 69.

  The RT state screen 730 shown in FIG. 9 includes a state occurrence display field 730a that displays that the RT state is occurring, a digest game number display field 730b that displays the number of digest games after the RT state has occurred, and the remaining This is a screen including an RT game number indicator 730c (the same specification as the RT game number indicator 710c) for displaying the accumulated RT game number. The RT state screen 730 in the figure illustrates that the number of digest games is 10 during the occurrence of the RT state, and that the remaining cumulative number of RT games is 60 games.

  Next, the operation of the slot machine 1 of the present example configured as described above will be described with reference to the flowcharts of FIGS. FIG. 10 is a flowchart showing a flow of RT game number acquisition processing for determining the number of RT games by the acquisition lottery, FIG. 11 is a flowchart showing a flow of RT generation processing for generating an RT state, and FIG. FIG. 10 is a flowchart showing a flow of RT end processing when an RT state ends.

  In the RT game number acquisition process shown in FIG. 10, it is first determined whether or not a BIG bonus state is occurring based on the flag state of the BIG flag (S101). When the BIG in-progress flag is on (S101: YES), a winning combination of 15 sheets is determined (S102). When the 15 winning combination is won (S102: YES), the acquisition lottery for determining the number of RT games is executed (S103).

  The RT game number determined by the winning lottery is added to the accumulated RT game number stored in the RT counter 341 (S104). If the indicator display flag is on (S105: YES), the display of the RT game number indicator 710c (see FIG. 7) is updated (S106). On the other hand, when the indicator display flag is off (S105: NO), the display update of the RT game number indicator 710c is not executed.

  In the RT generation process shown in FIG. 11, first, the flag state of the RT generation enable flag corresponding to the standby state is determined (S201). If the RT occurrence flag is on (S201: YES), the operation of the RT button 69 is determined (S202). Further, when the RT button 69 is operated (S202: YES), it is determined whether or not two winning combinations are won in the game (S203). When two winning combinations have been won (S203: YES), the right increase / decrease lottery for determining the increase / decrease number of the cumulative RT game number indicating the advantage of the special state occurrence right is executed (S204). .

  The new cumulative RT game number obtained by adding or subtracting the RT game number determined by the right increase / decrease lottery is stored in the RT counter 341 (S205). On the other hand, when the RT button 69 is operated and the two-game winning combination is not won (S203: NO), the right increase / decrease lottery is not executed, and therefore the cumulative number of RT games stored in the RT counter 341 increases or decreases. There is nothing to do.

  Thereafter, the RT flag corresponding to the RT state is set to the on state (S206), while the RT occurrence flag corresponding to the standby state is reset (S207). The RT state is generated by such flag control, and the display of the RT state screen 730 (FIG. 9) is started (S208).

  In the RT end process shown in FIG. 12, first, the flag state of the RT flag is determined (S301). If the RT flag is on, that is, the RT state is occurring (S301: YES), it is determined that the game is over (S302). When one game is consumed due to the end of the game (S302: YES), the cumulative RT game number stored in the RT counter 341 is subtracted by one game (S303).

  When the accumulated number of RT games is zero (S304: YES), the screen display of the liquid crystal display unit 53 returns to the normal screen (not shown) (S305), and RT is reset in response to zero reset of the RT flag (S306). The state ends and the normal state is restored. On the other hand, when the cumulative number of RT games is one game or more (S304: NO), the operation of the RT button 69 for ending the RT state is determined (S307). When the RT button 69 is operated (S307: YES), the RT occurrence flag corresponding to the standby state is set to the on state (S308). Thereafter, the screen display of the liquid crystal display unit 53 is switched to the RT standby state screen 720 (FIG. 8) (S309), and the RT state is terminated in response to zero reset of the RT flag (S306), and the normal state (standby state). Return to.

  In the game of the slot machine 1 configured as described above, a special state generation right that allows the player to generate the RT state at his / her own will is set. A player who has acquired the special state generation right can generate an RT state at a desired timing according to his / her gaming strategy. For example, the RT button 69 which is a special state generation operation means can be operated immediately to generate an RT state at an early stage, or an RT state can be generated after playing a game to some extent.

  As described above, the slot machine 1 according to the present example enables the player to adjust the timing of occurrence of the RT state, which is a special state, according to the player's own will. It is a slot machine with excellent characteristics that enhances its interest.

In this example, the RT state (replay time) is adopted as the special state, but it is not limited to this, and for example, an advantageous state for the player such as an assist time (AT) or a challenge time (CT). Any state may be used.
In this example, the RT state is generated immediately when the RT button 69 is operated in the standby state, but instead of this, after the RT button 69 is operated, a specific symbol is stopped and displayed. The RT state may be generated accordingly.

  In this example, no limit is set for the number of operations of the RT button 69 in the standby state, that is, the number of occurrences (start count) of the RT state, but a limit may be set instead. Alternatively, the minimum number of games that must be consumed in one RT state may be set so that the RT state cannot be terminated until the minimum number of games is consumed. If comprised in this way, the possibility that an operation rate will fall by the endless repetition of generation | occurrence | production and completion | finish of RT state can be avoided beforehand.

  In addition, the number of executions of the right increase / decrease lottery in which the cumulative RT game number increases / decreases, the total number of variable games in which the cumulative RT game number is added or subtracted according to the right increase / decrease lottery, It is also possible to display the average number of games of the variable game number. If these game data are displayed, the player can objectively grasp whether the execution of the right increase / decrease lottery was successful or unsuccessful.

This example is an example in which the right increase / decrease lottery is executed in response to the occurrence of the RT state. Instead, the right increase / decrease lottery is executed in response to the end of the RT state corresponding to the operation of the RT button 69. It is also good. Further, it is also possible to execute a right increase / decrease lottery at both the timing of the occurrence and termination of the RT state.
Furthermore, an advantageous right increase / decrease lottery with a high probability of increasing the number of accumulated RT games and a relatively unfavorable right increase / decrease lottery with a low probability of increase are set, and the types of right increase / decrease lotteries that can be currently executed are notified. It is also possible to provide a state. In a state where the type of right increase / decrease lottery is notified, a game strategy of generating an RT state, etc., aiming at a more advantageous generation timing is required, and the interest is further enhanced. On the other hand, in a state in which the type of right increase / decrease lottery is not notified, there is a pleasure that the generation timing is measured by the player's own intuition.

  This example is an example in which the right increase / decrease lottery is executed when an operation for generating an RT state is performed in a game in which two winning combinations are won. Various combinations other than the two-sheet combination can be set as an opportunity for the right increase / decrease lottery. In addition, regardless of whether or not a game in which an operation for generating an RT state has been performed is won, a right increase / decrease lottery may be executed in accordance with an internal winning of any combination.

Needless to say, the scope of the claims should not be construed as limited by the configuration, numerical values, or the like of the specific examples.
