In the gaming machine in which the corresponding row of symbols is stopped based on the stop operation by the player after the change is started, it is possible to give an advantageous game state that is a game in a state more advantageous to the player than the normal state A game control means for controlling, wherein the game control means is configured to be able to give a special game state capable of increasing a period of the advantageous game state during the advantageous game state. When the condition is established, the establishment information indicating that the specific condition is established is stored in the storage means. During the special gaming state, when the establishment information is not stored in the storage means, the special information is stored. Game If the regular continuous lottery is selected, the special gaming state will be continued, while the special gaming state will be terminated if the normal continuous lottery is lost. In the special gaming state, if the establishment information is stored in the storage means, a special continuation lottery is performed, and if the special continuation lottery is won, the special gaming state is stored while holding the establishment information. On the other hand, if the special continuation lottery is lost, the gist is to delete the establishment information from the storage means without ending the special gaming state.

  In the gaming machine, the game control means is more advantageous when the establishment information is stored in the storage means during the special gaming state than in the case where the establishment information is not stored in the storage means. You may make it give many opportunities to increase a period.

  In the gaming machine, the gaming control means has an opportunity to increase the period of the advantageous gaming state when the establishment information is not stored in the storage means at a predetermined opportunity during the special gaming state. On the other hand, when the establishment information is stored in the storage means, the opportunity to increase the advantageous gaming state period may be given a plurality of times.

  In the gaming machine, when the predetermined specific condition is satisfied during the special gaming state, the game control unit stores, in a storage unit, establishment information indicating that the specific condition is satisfied after a predetermined period. In the special gaming state, when the establishment information is not stored in the storage means and the specific condition is established, the special gaming state may be continued until the establishment information is stored. .

  In the above gaming machine, the game control means is configured to be able to set a plurality of reference periods during the special gaming state, and when an extra lottery executed corresponding to each reference period is won, By adding a reference period corresponding to the added lottery, the period of the advantageous gaming state is increased, and when the establishment information is stored during the special gaming state, than when the establishment information is not stored. A number of reference periods may be set, and each reference period may be configured to be longer each time the number of extra lottery wins executed corresponding to each reference period increases.

  According to the present invention, the special gaming state can be easily continued.

In order to set the number of bets in a state in which medals can be inserted into the floating game or the BET button 28 or the MAXBET button 29 can be operated, either the BET button 28 or the MAXBET button 29 is operated. When the BET button 28 is operated, credits equivalent to the number of one bet (one medal) from the stored and stored credits are set as the number of bets (the number of bets). Further, when the MAXBET button 29 is operated, credits corresponding to the maximum bet number that can be set in the target game (variable game) from the stored credits are set as the bet number (bet number). It should be noted that the pachi-slot 10 of the present embodiment allows a variable game with 3 bets.

  Also, in the pachislot machine 10, it is possible to set the number of bets by inserting a number of medals corresponding to the number of bets from the medal insertion slot 27, and when inserting one medal, the number of bets for one bet. Is set, and when three medals are inserted, the number of bets for three bets is set. When medals exceeding the maximum number of bets that can be set in the target game (3 bets in this embodiment) are inserted from the medal insertion slot 27, they are stored as credits when using the credit function. On the other hand, when the credit function is not used, the player pays out (returns) to the player from the medal discharge port 36 along a route (not shown).

  As shown in FIG. 2, in the pachi-slot 10 of this embodiment, one pay line is defined. When the player operates the BET button 28 and the MAXBET button 29, the respective bets are set and one pay line is set to be valid. When a winning line is activated, a combination of symbols displayed on the winning line is activated, and control (such as award medal payout) according to the combination of symbols displayed on the effective winning line is performed. Done. The variable game in this embodiment is configured so that one pay line is always valid.

  If the bet number is set as described above and the start lever 32 can be operated, that is, if the player performs a start operation to operate the start lever 32 in a state where the game can be started, each reel 13 of the drum unit DN can be operated. Is rotated, and a plurality of kinds of symbols are displayed on the fluoroscopic window 16 so as to continuously change. Thereafter, when each reel 13 rotates and a predetermined time elapses, the operation of each stop button 33 can be accepted. When each stop button 33 is operated by the player, each corresponding reel 13 is stopped, and symbols are displayed on the upper, middle and lower rows of the corresponding row from the fluoroscopic windows 16.

  When all of the reels 13 are stopped, a combination of symbols stopped and displayed on the activated pay line forms a predetermined award mode, and a prize corresponding to the winning award mode is obtained. Is given to the player. For example, when award medals are awarded as prizes, the number of medals corresponding to the winning prize form is awarded to the player as prize medals.

  In the pachi-slot 10 of the present embodiment, one change game (game) is started with the start operation of the start lever 32 as a start opportunity, and the combination of symbols is stopped and displayed (stopped) by the stop operation of the stop button 33. A one-time variable game (game) is performed. When award medals are paid out according to the combination of symbols, one variation game (game) is ended with the completion of the payout of the prize medals as an end opportunity.

  Based on FIG. 3, in the pachi-slot 10 of the present embodiment, a combination of symbols stopped and displayed on the winning line will be described. FIG. 3 shows a combination of symbols indicating combinations of symbols that can be stopped and displayed on the winning line based on a winning combination determined internally (stop result) and awards corresponding to the combinations of symbols. .

  In the present embodiment, when none of the symbol combinations corresponding to the winning combination shown in FIG. 3 is stopped and displayed on the valid winning line, one or more prize medals are not awarded to the player. It is like that. In the following, a symbol combination when a winning line is formed by a symbol combination that does not correspond to any of those shown in FIG.

  In addition, when [CHERRY / ANY / ANY] is stopped and displayed on the winning line, two prize medals are paid out. In this case, any symbol (“ANY”) may be used as the symbol that is stopped and displayed at the stop position of the middle reel 13C and the right reel 13R that form the winning line. Hereinafter, a combination of symbols when a winning line is formed by [cherry / ANY / ANY] is referred to as “cherry stop eye”. The cherry stop eye is determined to be able to win (can be stopped and displayed) when “cherry role” is determined as a winning combination in the internal lottery.

  When [Watermelon / Watermelon / Watermelon] is stopped and displayed on the winning line, it is determined that six award medals are to be paid out. Hereinafter, a combination of symbols when a winning line is formed by [watermelon / watermelon / watermelon] is referred to as “watermelon stop eye”. The watermelon stop eye is determined to allow winning (stop display is possible) when “watermelon combination” is determined as a winning combination in the internal lottery.

  Further, when [Bell Bell Bell] is stopped and displayed on the winning line, it is determined that nine prize medals are paid out. Hereinafter, a combination of symbols when a winning line is formed by [Bell Bell Bell] is referred to as a “bell stop eye”. The bell stop eye can be won (can be stopped and displayed) by determining either “bell role” as a winning combination in the internal lottery.

  For this reason, the “cherry role”, “watermelon role”, and “bell role” in this embodiment are the winning roles (payout roles) that determine that award medals are to be paid out based on the combination of symbols stopped and displayed on the winning line. )

  In addition, when [Replay / Replay / Replay] is stopped and displayed on the winning line, the player automatically sets the bet number without betting (without making a bet operation). Therefore, it is stipulated that a replay for performing the next variable game is given. Hereinafter, a combination of symbols when a winning line is formed by [Replay / Replay / Replay] is referred to as “normal replay stop eye”. The replay stop eye is determined to allow winning (stop display is possible) when “normal replay combination” is determined as the winning combination in the internal lottery.

  Further, when [Replay / Replay / Bell] or [Replay / Bell / Replay] or [Bell / Replay / Replay] is stopped and displayed on the winning line, a replay is provided. Hereinafter, a combination of symbols when a winning line is formed by [Replay / Replay / Bell] or [Replay / Bell / Replay] or [Bell / Replay / Replay] is referred to as “special replay stop eye”. The special replay stop eye is determined to allow winning (stop display is possible) when the “special replay role” is determined as the winning combination.

  For this reason, the “normal replay combination” and the “special replay combination” in this embodiment are the winning combination (hereinafter referred to as “replay combination”) that provides replay based on a combination of symbols that are stopped and displayed on the winning line. It is called "the role"). When a re-game is awarded, the player can play the next variable game without betting the number of bets. When the bet number is set by replaying, the same bet number as set in the variable game that has been given the opportunity to replay is set. In the replay role, only the next variable game can be played with the same number of bets as the variable game in which the replay role is stopped and displayed, and the medal is not paid out to the player as an award. Absent. In the present embodiment, the “cherry role”, “watermelon role”, “bell role”, and “replay role” described above are small roles.

  In addition, the pachi-slot 10 of the present embodiment is equipped with an RT function (re-game role probability change function) that controls the general game as the game state by changing the winning probability of the replay role. The general game in this embodiment is controlled to a state according to the operation mode of the RT function, and is controlled to a state according to the type during the operation of the RT function. In the general game by the RT function, the winning probability of the replay role (summation) in the general game is controlled to the low probability RT game in which the RT function is set to the low probability lottery state and in the general game. In some cases, the winning probability of the replay combination (summation) is controlled by a high-probability RT game that is an RT function that is set to a high-probability lottery state. In the following description, the term “low probability RT game” simply refers to a general game controlled by a low probability RT game, and the term “high probability RT game” refers to a high probability RT game. Means general games.

The electrical configuration of the pachi-slot 10 will be described with reference to FIG.
A main control board 40 for controlling the gaming machine is mounted on the back side of the pachislot machine 10. The main control board 40 executes various processes for controlling the gaming machine, calculates various control signals (control commands) according to the processing results, and outputs the control signals. In addition, a sub-control board 41 is mounted on the rear side of the machine to execute effect control according to the gaming state. The sub control board 41 receives various control signals output from the main control board 40 and executes predetermined control based on the control signals.

Hereinafter, the main control board 40 will be described.
Connected to the main control board 40 are each reel 13 (left reel 13L, middle reel 13C, and right reel 13R) constituting the drum unit DN, reel sensors SE1 to SE3, medal sensor SE4, sub control board 41, and hopper 38. ing. Further, various information display sections 19 provided on the central panel 15 are connected to the main control board 40. The main control board 40 includes a BET button 28, a MAXBET button 29, a checkout switch 31, a start lever 32, and stop buttons 33 (a left stop button 33L, a middle stop button 33C, and a right stop button 33R). Is connected. In addition, the effect display device 14, the speaker SK, and the lamp R are connected to the sub control board 41.

  The main control board 40 includes a main control CPU 40a, and a main control ROM 40b and a main control RAM 40c are connected to the main control CPU 40a. The main control CPU 40a receives the first to third position signals from the reel sensors SE1 to SE3 connected to the main control CPU 40a in accordance with the symbol (rotational position of each rotating reel 13) displayed on the see-through window 16. It has become so. The left reel 13L corresponds to the first position signal, the middle reel 13C corresponds to the second position signal, and the right reel 13R corresponds to the third position signal. The main control CPU 40a grasps the rotation position and stop position of each reel 13 from the first to third position signals, and controls the rotation and stop of each reel 13 based on the first to third position signals. I do. A medal detection signal is input to the main control board 40 (main control CPU 40a) every time a medal is detected from the connected medal sensor SE4.

  When the connected BET button 28, MAXBET button 29, checkout switch 31, start lever 32 and stop button 33 are operated, the main control CPU 40a receives various operation signals indicating that each button has been operated.

  Further, the main control CPU 40a executes random number update processing (random number generation processing) for updating values of various random numbers such as winning combination determination random numbers used in various lotteries at predetermined intervals. The winning combination determination random number is a random number used when the main control CPU 40a determines a combination (winning combination based on the winning information group) based on the winning combination determination table. The winning information group determined by the main control CPU 40a is associated with one or more winning combinations that can be won in the variable game. In the winning information group, when a single winning combination is associated, it means a single winning of the corresponding winning combination, and when a plurality of winning combinations are associated, it means a duplicate winning of these winning combinations. . For this reason, the main control CPU 40a determines a winning combination for winning by determining a winning information group.

  The main control ROM 40b stores a main control program. The main control ROM 40b stores a plurality of winning combination determination tables. In each winning combination determination table, the internal winning probability for each gaming state and each winning information group is the value of the winning combination determining random number. It is determined according to the allocation range. Further, in the main control ROM 40b, a stop table of symbol combinations for each combination is determined in advance. The stop table is a table in which symbols to be stopped and displayed are determined for each combination according to the operation timing when each stop button 33 is operated by the player. The main control RAM 40c stores (sets) various information that can be appropriately rewritten during the operation of the pachislot 10.

The winning combination determination tables T1 and T2 stored in the main control ROM 40b will be described with reference to FIGS.
In the main control ROM 40b, the type of winning information group to be selected by lottery and the winning probability of each winning information group to be selected by lottery (more specifically, a random value (random number value assigned to each winning information group to be selected by lottery) A table of the range)) for each gaming state is stored. Each winning combination determination table is used by the main control CPU 40a according to the gaming state. If it is a general game, the winning combination determination table T1 is associated with the low-probability RT game, and the winning combination determination table T2 is associated with the high-probability RT game.

  As shown in FIG. 5 (a), the winning combination determination tables T1 and T2 define the winning probabilities of the cherry, watermelon, bell, and replay roles. In the general game, the winning combination random number is distributed so that the winning probability of the replay role is higher in the high probability RT game (1 / 1.7) than in the low probability RT game (1 / 7.3). ing. For this reason, in the high probability RT game in which the winning probability of the replay role is set to the high probability lottery state, it is possible to reduce the consumption (injection) of medals held by the player as the replay is easily given. It can be given to players. Such a high-definition RT game is advantageous for the player.

  Note that the winning probability of the replay role shown in FIG. 5A is the winning probability in which the winning probability of the winning information group corresponding to the single winning of the normal replay role is associated with the overlapping winning of the normal replay role and the special replay role. The sum of the winning probability of the information group is specified. In the winning information group in which the overlapping winnings of the normal replay role and the special replay role are associated, a special overlapping replay group 1, a special overlapping replay group 2, a special overlapping replay group 3, and a special overlapping replay group 4 are set. . In addition, the winning probability of the bell combination shown in FIG. 5A defines the sum of the winning probabilities of the winning information groups associated with the bell combination. In the winning information group for the bell role, a bell group 1, a bell group 2, and a bell group 3 are set.

  Further, as shown in FIG. 5B, the winning probability of the above-mentioned replay role is the winning information in which the duplicated winnings of the normal replay role and the special replay role are associated with each other in the low probability RT game (winning role determination table T1). Defines the sum of the group's winning probabilities. In the winning information group in which the overlapping winnings of the normal replay role and the special replay role are associated, a special overlapping replay group 1, a special overlapping replay group 2, a special overlapping replay group 3, and a special overlapping replay group 4 are set. .

In addition, the above-described winning probability of the replay role defines the winning probability of the winning information group associated with the single winning of the normal replay role in the highly reliable RT game (winning role determination table T2).
In the following description, the phrase “winning a normal replay role” means winning a winning information group associated with a single winning of a normal replay role. The term “special replay winning” means winning of the special overlapping replay groups 1 to 4. In addition, in the case of “winning of the bell role”, it means winning of the bell groups 1 to 3. The term “cherry winning” means winning of a winning information group associated with a single winning cherry. The term “watermelon winning” means winning of a winning information group associated with a single watermelon winning.

Hereinafter, the sub control board 41 will be described.
The sub-control board 41 includes a sub-control CPU 41a, and a sub-control ROM 41b and a sub-control RAM 41c are connected to the sub-control CPU 41a. The sub-control ROM 41b stores sub-control programs for performing various game effects. In addition, the sub control ROM 41b has a display effect pattern showing the display effect mode of the effect display device 14, a sound effect pattern showing the sound output mode of the speaker SK, and a light emission effect pattern showing the light emission mode of the lamp R. Is remembered. The sub-control RAM 41c stores (sets) various information that can be appropriately rewritten during the operation of the pachislot 10. Specifically, in the sub control RAM 41c, sub state information (flags, etc.) relating to the gaming state is stored (set) by the sub control CPU 41a.

Hereinafter, processing related to the variable game executed by the main control CPU 40a based on the main control program will be described.
When the main control CPU 40a receives various operation signals, the main control CPU 40a executes predetermined control determined by the various operation signals. The main control CPU 40a executes display control of the various information display units 19 each time by inputting various operation signals and performing various controls. When the main control CPU 40a pays out an award medal based on a prize-type winning, the main control CPU 40a outputs a drive signal to the hopper 38 when the credit upper limit number (in this embodiment, “50 (sheets)”) is exceeded. Thus, each time a drive signal is output, control is performed so that one award medal is paid out. The main control CPU 40a outputs a drive signal to the hopper 38 at the time of credit settlement, and controls the player to pay out medals for the credit.

  The main control CPU 40a sets the bet number when a medal is inserted from the medal insertion slot 27 or when an operation signal of the BET button 28 or the MAXBET button 29 is input. The main control CPU 40a updates the number of credits every time the BET button 28 or the MAXBET button 29 is operated. Similarly, the main control CPU 40a updates the number of credits every time a medal is inserted. Then, the main control CPU 40a causes a game startable state in which a variable game can be performed when the bet number of 3 bets is set.

  Subsequently, in a state where the game can be started, the main control CPU 40a performs a role lottery (internal lottery) when an operation signal of the start lever 32 is input. That is, the main control CPU 40a acquires the value of the winning combination determination random number from the main control RAM 40c, and the value belongs to the value range of each winning information group of the winning combination determination table stored in the main control ROM 40b. A role lottery is performed to determine whether or not he / she is. In the role lottery, the main control CPU 40a determines a winning information group to be won using a winning combination determination table corresponding to the gaming state. The main control CPU 40a recognizes the gaming state by setting state information (such as a flag) indicating the gaming state in the main control RAM 40c. In the present embodiment, the main control CPU 40a serves as a winning combination determining means for performing a lottery.

  When the main control CPU 40a determines the winning information group (winning combination), the main control RAM 40c stores (sets) the combination information (flag or the like) indicating the type of winning combination associated with the determined winning information group. ) When the winning of the small role is determined, the main control CPU 40a determines the small role of the main control RAM 40c with the end of the variable game (one time) subject to the role lottery regardless of whether or not the small role is won. Erase the role information. For this reason, the winning combination is determined to be valid only in one variation game, and a combination that cannot be carried over over the subsequent variation games regardless of whether or not it is won.

  Subsequently, the main control CPU 40a controls each reel 13 so as to start the rotation operation of each reel 13 in a state where the wait time has elapsed since the end of the immediately preceding variable game. Further, the main control CPU 40a instructs the start of the variable game in accordance with the start of the rotation operation of each reel 13, and sub-commands the variable game start command indicating the lottery result of the role lottery and the game state in which the variable game is performed. The data is output to the control board 41 (sub control CPU 41a). This variable game start command instructs a combination of a plurality of combination information if the winning combination is duplicate. Note that the variable game start command to the sub control board 41 (sub control CPU 41a) may be output at the timing when the player has operated the start lever 32 (after performing a lottery or the like).

  Subsequently, when the CPU 40a for main control inputs various operation signals of each stop button 33 based on the player's operation, it performs control (stop control) for stopping the reel 13 corresponding to the various operation signals. Further, the main control CPU 40a determines, based on the position signals from the reel sensors SE1 to SE3 corresponding to the reels 13, that each reel 13 is changing and each reel 13 is changing and each reel 13 is stopped. The stop state of the reel 13 is grasped. The main control CPU 40a maintains the rotating operation without performing stop control on the rotating reel 13 until various operation signals are input from the stop button 33.

  Further, when various operation signals for the stop button 33 are input, the main control CPU 40a outputs the various operation signals to the sub control CPU 41a. With the various operation signals of the stop button 33, the sub control board 41 (sub control CPU 41a) recognizes the operation state of the stop button 33 by the player. That is, the sub control board 41 (sub control CPU 41a) is made aware of which stop button 33 has been operated and the order in which the stop button 33 has been operated.

Next, stop control performed by the main control CPU 40a will be described.
The main control CPU 40a stops each reel 13 within a predetermined stoppable range (maximum of 4 symbols) from the timing when each stop button 33 is operated by the player based on the determined winning information group (winning combination). To stop display any combination of symbols. When stopping each reel 13 that is rotating, the main control CPU 40a stops and displays a combination of symbols based on the winning combination that has been won and the operation timing of each stop button 33 based on the stop table stored in the main control ROM 40b. Perform stop control. For this reason, each reel 13 does not necessarily stop at the timing of the stop operation by the player of the stop button 33, and the timing of the stop operation by the player and the timing at which each reel 13 stops do not match (so-called “ Slip "). For example, in the control with “slip”, when the timing of the stop operation by the player for the symbol to be stopped is early, each reel 13 is forcibly slid in each variation direction to stop the symbol to be stopped on the winning line. .

  For this reason, in each reel 13, if other types of symbols sandwiched between the types of symbols to be stopped do not have five or more portions, as a result of slip control, the reels 13 stop on any winning line. It is possible to stop the display of the type of symbol that is desired. On the other hand, in each reel 13, if the other types of symbols sandwiched between the types of symbols to be stopped have five or more portions, even if the slip control is involved, it is stopped at any winning line. There are cases where the desired type of symbol cannot be stopped and displayed.

  Therefore, the main control CPU 40a stops and displays the cherry stop eye when the timing of the stop operation by the player is performed at a predetermined timing when the cherry role is won. On the other hand, the main control CPU 40a stops and displays the stop stop eye when the timing of the stop operation by the player is not performed at a predetermined timing when the cherry role is won. In this case, the cherry role is missed.

  Further, the main control CPU 40a stops and displays the watermelon stop eye when a stop operation is performed by the player when the watermelon role is won. On the other hand, the main control CPU 40a stops and displays the off-stop stop eye when the stop operation timing by the player is not performed at a predetermined timing when the watermelon role is won. In this case, a watermelon role is missed.

Next, stop control at the time of winning the bell role will be described.
The main control CPU 40a of the present embodiment is different in control performed based on the pressing order of operating the three stop buttons 33 when the bell combination is won. That is, for each bell group, a bell winning push order for stopping and displaying the bell stop eye is determined. Also, in order to cope with this, the order of pushing the bell spilling to stop and display the bell spilling stop of the dedicated stop eye (for example, [Bell / Bell / Watermelon]) is determined for each bell group. ing.

  The main control CPU 40a stops and displays the bell stop eye on the winning line by operating the stop button 33 in the push order for the bell winning based on the winning of the bell role. This bell stop eye is stopped and displayed regardless of the timing of the stop operation by the player. On the other hand, the main control CPU 40a operates the stop button 33 in the pressing order for bell spilling based on the winning of the bell role, thereby stopping and displaying the bell spilling stop eye on the winning line. This bell-spilling stop eye is stopped and displayed regardless of the timing of the stop operation by the player.

  More specifically, in the bell group 1, if the left stop button 33L is the first, the stop operation regardless of the subsequent order is determined in the pressing order for the bell winning prize, and other than the left stop button 33L is the first. If there is, stop operation in any order is determined in the order of pushing for bell spilling. Further, in the bell group 2, if the middle stop button 33C is the first, the stop operation regardless of the subsequent order is determined in the pressing order for the bell winning prize. Stop operation in any order is determined in order of pushing for bell spill. Further, in the bell group 3, if the right stop button 33R is the first, the stop operation regardless of the subsequent order is determined in the pressing order for the bell winning prize. Stop operation in any order is determined in order of pushing for bell spill. For this reason, in the bell groups 1 to 3, the pressing order of “3 choices” based on the stop button 33 that is stopped first is determined.

Next, stop control at the time of winning the replay combination will be described.
When the main control CPU 40a wins the normal replay role, the main control CPU 40a stops and displays the normal replay stop eye according to the normal winning stop mode that becomes [Replay / Replay / Replay] regardless of the timing of the stop operation by the player. .

Further, in the present embodiment, the control performed based on the pressing order of operating the three stop buttons 33 is different when the replay winning combination is won in the replay winning combination.
In the following description, [left → middle → right], [first left], and the like indicate the order in which the reels 13 are stopped, that is, the stop operation order of the stop button 33 in order from the front. The notation [left → middle → right] means stop operation in the order of the left stop button 33L → middle stop button 33C → right stop button 33R, and the notation of [first left] if the left stop button 33L is the first. It means a stop operation regardless of the subsequent order.

  Specifically, as shown in FIG. 6, a special push order that is a mode of a stop operation for stopping and displaying the special replay stop eye is defined for each special overlapping replay group. Further, in order to correspond to this, a normal pressing order that is a mode of a stop operation for stopping and displaying the normal replay stop eye is determined for each special overlapping replay group.

  When the main control CPU 40a wins the special replay role and the player performs a stop operation in the special push order, the special replay stop mode (“special stop mode”) according to the special winning stop mode (specific stop mode) is performed on the winning line. ”) Is stopped. The special replay stop eye according to the special winning stop mode can be stopped and displayed regardless of the timing of the stop operation by the player.

  On the other hand, when the main control CPU 40a wins the special replay role and the player performs a stop operation in the normal push order, the normal replay stop mode (normal stop mode) is stopped on the pay line (normal stop mode) “Normal”) is stopped. The normal replay stop eye in the normal winning stop mode can be stopped and displayed regardless of the timing of the stop operation by the player.

  For example, the special overlap replay group 1 has a special push order of [middle → left → right], [middle → right → left], [right → left → middle], and [right → Normal → left] push order is defined. In addition, the special duplication replay groups 1 to 4 have a [first left] normal push order regardless of the type of the winning information group. For this reason, the special overlapping replay groups 1 to 4 are determined to have a push order of “4 options without left” that does not have a special push order according to [first left].

  The main control CPU 40a makes a winning determination when all the reels 13 are stopped and the symbol combination is stopped and displayed. In this case, the main control CPU 40a reads out the combination information from the main control RAM 40c, and performs a winning determination for determining whether a combination of symbols corresponding to the read combination information (winning combination) is stopped and displayed on the winning line. . Further, in the winning determination, the main control CPU 40a identifies the combination of symbols stopped and displayed on the winning line from the position signal input as each reel 13 stops, and the combination is useful. It is determined whether or not the prize mode corresponds to the information (winning combination). The main control CPU 40a determines winning (affirmative) when the combination of symbols stopped and displayed on the winning line is the winning mode corresponding to the winning information (winning winning combination), while the winning information is included in the winning information (winning winning combination). If it is not the corresponding prize mode, it is determined that the prize is not won (denial).

  When the main control CPU 40a determines that the winning is determined in the winning determination, the main control CPU 40a performs control according to the award mode. In this case, the main control CPU 40a performs control for shifting the gaming state and control for paying out a prize medal in accordance with the prize mode. Further, when determining the winning by the winning determination, the main control CPU 40a outputs a winning instruction command indicating that the winning is made to the sub-control board 41 (sub-control CPU 41a). This winning instruction command causes the sub control board 41 (sub control CPU 41a) to recognize that the winning combination designated by the variable game start command has won. In addition, in this winning instruction command, the sub-control board 41 (sub-control CPU 41a) recognizes which stop eye (winning mode) is won along with winning.

  When determining the winning of the cherry role, the main control CPU 40a performs control to pay out two prize medals. On the other hand, the main control CPU 40a does not give a prize medal when the winning of the cherry role is not determined based on the shift stoppage time when the winning of the cherry role is not determined (when the missing of the cherry role is determined). Further, the main control CPU 40a performs control for paying out six award medals when determining the winning of the watermelon role. The main control CPU 40a does not grant a prize medal when not winning a watermelon role based on the stoppage of a watermelon when winning a watermelon role (when determining whether a watermelon role is missed). The main control CPU 40a performs control for paying out nine award medals when determining the winning of the bell role. On the other hand, the CPU 40a for main control does not give a prize medal when the winning of the bell role is not determined based on the stoppage of the shift and when the winning of the bell role is not determined (when the missing of the bell role is determined).

  Further, the main control CPU 40a performs control for replaying the next variable game when determining the replay winning combination. In the control for replaying, the main control CPU 40a sets the same bet number as that of the variable game for which the winning is determined. Further, when determining the winning of the special replay role in the low-probability RT gaming state, the main control CPU 40a also ends the low-probability RT game and controls the gaming state to shift from the next variable game to the high-probability RT game. Will do.

Based on FIG. 7, the mode of transition of the gaming state controlled by the main control CPU 40a based on the variable game according to the gaming state will be described.
When the main control CPU 40a wins the special replay role (communication + special (replay)) during the low-probability RT game, when the stop operation is performed according to the normal push order of “no left 4 choices” Then, a normal winning is generated and the low probability RT game is continued (maintained) in response to the winning. On the other hand, if the main control CPU 40a wins the special replay role (communication + special (replay)) during the low-probability RT game, the stop operation by the special push order of “no left 4 choices” is performed. Then, a special winning is generated, and then the next variable game is shifted to the high-definition RT game.

  For this reason, in the low probability RT game, when the special replay stop eye that wins the special replay role and wins a special prize is stopped and displayed, the transition condition to the high probability RT game is satisfied. In addition, the low-probability RT game is continued when the special replay combination is won and the normal replay stop eye, which is a normal win, is stopped and displayed, and the transition condition to the high-probability RT game is not satisfied.

  In addition, when the main control CPU 40a wins the bell role during the high-definition RT game, the stop operation is performed by the pushing order for the bell winning prize, so that the bell winning is generated and triggered by that, the high-definition RT game Continue (maintain). On the other hand, if the main control CPU 40a wins the bell role during the high-definition RT game, a stop operation is performed according to the pushing order for the bell spill, which causes a bell spill and triggers the low-probability RT game. Shift to (low accuracy RT).

  Note that when the gaming state is shifted, the main control CPU 40a outputs a state instruction command indicating the transitioned gaming state to the sub-control board 41 (sub-control CPU 41a). This state instruction command causes the sub-control board 41 (sub-control CPU 41a) to recognize which game state is managed by the main control CPU 40a.

Next, a process related to a variable game executed by the sub control CPU 41a based on the sub control program will be described.
When the sub-control CPU 41a inputs various commands such as a variable game start command and a winning instruction command, the sub-control CPU 41a controls the display contents of the effect display device 14 so as to execute various effects based on the contents instructed by the commands. . In addition, when the state instruction command is input, the sub control CPU 41a stores (sets) sub state information indicating which gaming state is controlled in the sub control RAM 41c. Thus, the sub control CPU 41a sets the sub status information and grasps the gaming state controlled by the main control CPU 40a. The sub-control CPU 41a performs control related to various effects every time a variable game start command is input. Note that the sub-control CPU 41a grasps the winning combination missed (non-winning) instructed by the variable game start command when the winning instruction command is not input. Further, since the sub-control CPU 41a can grasp the stop state of each reel 13, it can also grasp the winning combination missed from this stop state.

  As shown in FIG. 7, the sub control CPU 41a controls the effect state of the effect display device 14 in accordance with the gaming state controlled by the main control CPU 40a. The player plays a variable game (game) according to the effect state of the effect display device 14. In such an effect state, the player is made aware of the game state based on the type, or an effect that allows the player to play the game advantageously is performed. The production states in this embodiment are classified into a plurality of types as shown in FIG.

  More specifically, the effect state includes a normal mode that can be performed when the game state is mainly a low-probability RT game. In the normal mode, the effect display device 14 displays an image of the display screen for the normal mode. This normal mode is performed mainly when the winning probability of the replay role is in a low-probability lottery state, and is a state in which no special prize or bell winning effect is performed.

  Further, the effect state includes an ART mode that is performed when the game state is mainly a high-definition RT game. In the ART mode, the effect display device 14 displays an image of the display screen for the ART mode. This ART mode is performed mainly when the winning probability of the replay role is in a high-probability lottery state, and an effect that assists in the Bell winning is performed. Thus, in the ART mode, avoidance of missing the bell role is assisted, and winning of a prize medal based on the winning of the bell role is assisted. For this reason, the ART mode becomes an advantageous state (advantageous gaming state) for the player.

  The effect state includes a preparation mode that is performed in association with a situation when the game state is a low-probability RT game and a right to shift to the ART mode described later (with an ART flag) is generated. In this case, the effect display device 14 displays an image of the display screen for the preparation mode. In this case, the effect display device 14 is configured to be roughly the same as the display screen for the normal mode, and a character string such as “standby” is displayed as an image on the display screen. This preparatory mode is a state where the winning probability of the replay role is a low-probability lottery state, as in the normal mode, while the special win and the bell win are performed.

  In addition, the effect state includes an addition mode as a special game state performed when the game state is a high-definition RT game. In this case, the effect display device 14 displays an image of the display screen for the addition mode. This extra mode is a high-probability lottery state in which the winning probability of the replay role is the same as the ART mode, and an effect to assist (assist) the winning of the bell role is performed.

  In the present embodiment, the sub control CPU 41a sets the effect flag (information) indicating the type of effect state in the sub control RAM 41c, thereby grasping the controlled effect state. Then, the sub-control CPU 41a selects the image display data for the background image corresponding to the effect flag, and controls the display content (display screen) of the effect display device 14 based on the selected image display data. To do. In the present embodiment, the sub control CPU 41a is a game control means.

  Based on FIG. 7, the control content in each effect state is demonstrated with the display effect in the effect display apparatus 14. FIG. As a result of performing the control in each production state described below, the sub-control CPU 41a performs control so as to shift the production state in the mode shown in FIG.

First, the control contents in the normal mode will be described.
The sub-control CPU 41a controls the normal mode when the gaming state is mainly a low-probability RT game. Note that the sub-control CPU 41a may control the normal mode even when the gaming state is a high-definition RT game. Then, the sub-control CPU 41a performs processing based on winning and winning instructions of the winning combination during control in the normal mode. During the control of the normal mode of the low probability RT game, winning and winning of the cherry role, watermelon role, bell role, and replay role can be instructed. During the normal mode, a special replay winning combination, a normal winning or a special winning based on the winning of the special replay winning is instructed. Further, during the normal mode, as a replay role, a win for the normal replay role and a normal winning based on this are instructed.

  Further, the sub-control CPU 41a navigates the push order corresponding to the winning bell combination when the winning of the bell combination that requires the pressing order of the stop button 33 in the winning combination is instructed. The effect display device 14 is controlled so that the effect is not performed. That is, it is difficult to win a bell role during the normal mode. In the normal mode, the player can win a prize when operated in the pressing order corresponding to the winning bell role when the winning bell role is won.

  Further, the sub-control CPU 41a does not cause an effect to assist the special winning when the winning of the special replay combination whose stop mode changes depending on the pressing order of the stop button 33 among the small combinations is instructed. 14 display contents are controlled. For this reason, special winnings are difficult during the normal mode. On the other hand, during the normal mode, when a special replay role is won, a special prize occurs when a player happens to stop in a special push order.

  Further, the sub-control CPU 41a controls the effect state so that the normal mode is continued when the normal winning is instructed based on the winning of the special replay combination (when the special order is not pressed). In this case, the low probability RT game is continued in the game state. Further, the sub-control CPU 41a controls the effect state so that the normal mode is continued even when the special winning is instructed based on the winning of the special replay role (when the special push order is used). On the other hand, the gaming state is shifted to a high probability RT game.

  Further, the sub-control CPU 41a performs an ART entry lottery when the winning of a small role is instructed during the normal mode. In this ART rush lottery, random numbers are assigned to either “winning” or “non-winning” so that a predetermined winning probability (for example, the sum is 1/260) based on the winning combination instructed to win. Done. Then, the sub-control CPU 41a generates the right to shift to the ART mode when deriving the “winning” result in the ART entry lottery, while in the ART mode when deriving the “non-winning” result in the ART entry lottery. Does not generate the right to transfer. In the ART entry lottery of the present embodiment, random numbers are distributed so that the ART initial hit probability that is “winning” calculated in consideration of the winning probability of each winning combination is approximately 1/260.

  The random numbers used for the ART entry lottery and various lotteries described later are updated every predetermined cycle and stored in the sub-control RAM 41c. Then, the sub control CPU 41a acquires random numbers used in the lottery from the sub control RAM 41c when performing various lotteries, and performs random lottery based on the acquired random numbers.

  When the sub-control CPU 41a generates the right to shift to the ART mode, the sub-control CPU 41a sets information indicating the generation of the right to shift to the ART mode in the ART flag stored in the predetermined storage area of the sub-control RAM 41c. To do. The information indicating the occurrence of the right to shift to the ART mode is canceled when the ART mode to be shifted to after the occurrence ends, and the setting is retained when the ART mode is interrupted.

  In the following description, “with an ART flag” indicates that information indicating the occurrence of the right to shift to the ART mode is set in the ART flag. Further, “no ART flag” indicates that the information indicating that the right to shift to the ART mode is not set in the ART flag.

  Then, the sub-control CPU 41a derives the result of "winning" in the ART entry lottery, and when the ART flag is present, the sub-control CPU 41a generates the right to shift to the ART mode from the variable game or the variable game after a predetermined number of times. The production state is controlled so as to shift to the preparation mode for notification. In this case, the low probability RT game is continued in the game state. The sub-control CPU 41a controls the effect state so as to continue the normal mode when the result of “non-winning” is derived in the ART entry lottery.

  Further, the sub-control CPU 41a gives a penalty that is disadvantageous to the player if the left stop button 33L is not operated first during the normal mode control. For example, as a penalty, even if a special replay winning combination is instructed, the production state is not shifted to the ART mode, the ART rush lottery is not performed, or the ART rush lottery is performed, but the result of “non-winning” is always To be derived. In addition, the special replay combination does not include the pressing order starting with the operation of the left stop button 33L. This prevents the transition to the ART mode during the normal mode.

Next, the preparation mode will be described.
The sub-control CPU 41a shifts the effect state from the normal mode to the preparation mode while the ART flag is present (there may be a case where a predetermined number of times have passed) in the normal mode. In the preparation mode, the low probability RT game continues. During the control of the low-probability RT game preparation mode, winning of a cherry role, watermelon role, bell role, and replay role and winning can be instructed. Further, during the preparation mode, a special replay winning combination, a normal winning or a special winning based on the winning of a special replay winning is instructed.

  Further, during the preparation mode, the sub-control CPU 41a causes the “bell navigation effect” to assist the bell winning when the winning combination of the bell combination whose stop mode changes depending on the pressing order of the stop button 33 among the small combinations is instructed. Thus, the display content of the effect display device 14 is controlled. For this reason, during the preparation mode, an effect is performed so as to assist the bell winning, and the player wins a bell when the player performs a game according to the bell navigation effect.

  Explaining the bell navigation effect, the effect display device 14 displays three images simulating each stop button 33 side by side, and an image “1” indicating that one of the three buttons should be operated first is attached. Is done. For example, the bell navigation effect in which “1” is added in the middle of the three images imitating the stop button 33 informs the player that the middle stop button 33C should be operated first.

  Further, the sub-control CPU 41a controls the display content of the effect display device 14 so that a bell navigation effect is performed in accordance with the start of the variable game when the winning of the bell role is instructed. In addition, the sub-control CPU 41a performs a bell navigation effect with the content of informing the bell winning push order corresponding to the bell combination instructed to win. For example, in the case of the bell group 2, the sub-control CPU 41a causes the bell navigation effect of the content to notify that the middle stop button 33C should be operated first.

  In addition, the sub-control CPU 41a performs a “special navigation effect” for assisting a special winning when the winning of a special replay combination whose stop mode changes depending on the pressing order of the stop button 33 among the small combinations is instructed. The display content of the effect display device 14 is controlled. For this reason, during the preparation mode, an effect is performed so as to assist the special winning, and a special winning occurs when the player plays the game according to the special navigation effect.

  In the effect display device 14, three images simulating the stop button 33 are displayed side by side, and any number of “1”, “2”, and “3” is shown so as to indicate a special pressing order for the three. Each of the images is attached. For example, a special navigation effect with “1” in the middle of three images simulating each stop button 33, “2” on the left, and “3” on the right, the stop button 33 is [middle → left → right]. ] To inform the player that the operation should be performed in the pressing order.

  Further, when the special replay winning combination is instructed, the sub control CPU 41a controls the display content of the effect display device 14 so that the special navigation effect is performed in accordance with the start of the variable game. Further, the sub-control CPU 41a causes the special navigation effect to be performed with the content informing the special push order corresponding to the special replay combination instructed to win. For example, in the case of the special overlap replay group 2, the sub-control CPU 41a performs a special navigation effect with a content for notifying that the stop button 33 should be operated in the order of [middle → right → left].

  When the special winning is instructed as a result of performing the special navigation effect (when pressed in the special pressing order), the sub-control CPU 41a ends the preparation mode and shifts to the ART mode. Control the production state. In this case, the gaming state is shifted to a high probability RT game. On the other hand, the sub-control CPU 41a controls the effect state so as to continue the preparation mode when the normal winning is instructed as a result of performing the special navigation effect (when pressed in the normal push order). To do. In this case, the low probability RT game is continued in the game state.

  In such special navigation effects, other than [first left], which is the special push order of the special overlap replay group, and the mode of the stop operation that is the subject of the penalty is informed in the normal mode. The For this reason, the sub-control CPU 41a allows the transition to the ART mode when the above-mentioned [first left] is not performed for the variable game in which the special navigation effect is performed in the preparation mode (the penalty is given). Not). Therefore, the transition to the ART mode is realized during the preparation mode with the ART flag.

Next, the contents of control in the ART mode will be described.
The sub-control CPU 41a controls to the ART mode when the gaming state is mainly a high probability RT game. Further, the sub-control CPU 41a may control the ART mode even when the gaming state is a low probability RT game. Further, the sub-control CPU 41a performs processing based on winning and winning instructions of the winning combination during the control of the ART mode. In addition, during the control of the ART mode of the high-definition RT game, winning of the cherry role, watermelon role, bell role, and replay role and winning can be instructed.

  Further, the sub-control CPU 41a displays the effect so that the “bell navigation effect” is performed in the same manner as in the preparation mode when the winning of the bell role whose stop mode changes depending on the pressing order of the stop button 33 among the small roles is instructed. The display content of the device 14 is controlled. For this reason, during the ART mode, an effect is performed so as to assist the bell winning, and when the player performs the game according to the bell navigation effect, the bell spill is avoided, and the bell winning is generated.

  The sub-control CPU 41a controls the effect state so as to continue the ART mode when a bell winning is instructed. In this case, in the gaming state, the high-definition RT game is continued. Further, the sub-control CPU 41a terminates the ART mode when the bell spill is instructed and the remaining number of games indicating the number of variable games that can be performed in the ART mode is 1 or more, and prepares the mode. The production state is controlled to shift to. In this case, the gaming state is shifted to a low probability RT game.

  Further, the sub control CPU 41a stores the number of remaining games indicating the number of variable games that can be performed in the ART mode in a predetermined storage area of the sub control RAM 41c. The number of remaining games is also the number of times that a variable game can be performed for various assistances of the player's game by means of a bell navigation effect or the like in the ART mode.

  Note that the sub-control CPU 41a continues to hold the number of remaining games until the ART mode is ended even when the state is shifted to another effect state. For this reason, when the sub-control CPU 41a interrupts the ART mode and shifts to another effect state (for example, an add-on mode to be described later), after the other effect state ends, the sub-control CPU 41a uses the number of remaining games at the point of interruption. Restart ART mode. In the following description, the case where the remaining game number is “0 (zero)” is referred to as the remaining game number being not set. Further, when the remaining game number is other than “0 (zero)” (≧ 1), it is said that the remaining game number is being set.

  The sub-control CPU 41a adds [50 (times)] as the number of remaining games when the production state is shifted to the ART mode while the number of remaining games is not set. The sub-control CPU 41a subtracts “1” from the remaining number of games stored in the sub-control RAM 41c every time the start of the variable game is instructed in the ART mode. As described above, the sub-control CPU 41a counts the number of times that the variable game can be performed in the ART mode based on the execution of the variable game.

  The player is notified of the number of times the variable game is performed in the ART mode by using the effect display device 14. Therefore, the sub control CPU 41a controls the display content of the effect display device 14 so as to notify the number of remaining games stored in the sub control RAM 41c during the ART mode. In addition, when the number of remaining games stored in the sub control RAM 41c is “0 (zero)”, the sub control CPU 41a causes the effect display device 14 to perform an end effect to notify the end of the ART mode. Control display content. The sub-control CPU 41a sets no ART flag.

  During such an end effect, since the number of remaining games is not set, the sub-control CPU 41a controls the display content of the effect display device 14 so that the bell navigation effect is not performed even if the bell role is won. To do. For this reason, during the end effect, the effect is performed so as to make it difficult to avoid bell spillage, that is, to win a bell. Then, after the end effect is reached, the sub control CPU 41a controls the effect state so as to shift to the normal mode when the bell spills. In accordance with this, the gaming state is shifted to a low probability RT game. If the player happens to stop in the push order for winning a bell during the winning stage, the player wins a bell.

  In the present embodiment, in the ART mode, when a predetermined transition condition is satisfied, the effect state is shifted to the addition mode. During this extra mode, there is a case where a privilege (hereinafter referred to as “ART extra”) is given by adding the number of ARTs in the ART mode to the number of remaining games.

  Further, in the present embodiment, when a predetermined parallel condition is further satisfied during the addition mode, apparently, the two addition modes are executed in parallel. For convenience of explanation, when the transition condition is satisfied during the ART mode, the first addition mode that is shifted first is referred to as a first addition mode. In addition, when the parallel condition is satisfied during the first addition mode, the addition mode that is executed in parallel is referred to as a second addition mode. In addition, when only the second addition mode is executed, the addition mode that is executed in parallel when the parallel condition is satisfied is the first addition mode.

  The two extra modes are executed in parallel, so that each opportunity for giving a privilege is given. Further, when the two extra modes are executed in parallel, if the continuous lottery is lost, not all the extra modes are ended, and the single extra mode is returned. Hereinafter, the control related to the addition mode will be described in detail.

First, the transition condition that triggers the transition of the addition mode and the processing after the transition condition is satisfied will be described.
When the main control CPU 40a wins the watermelon role or the cherry role in the high-definition RT game, the main control CPU 40a instructs the sub control CPU 41a that the watermelon role or the cherry role is won. When the sub-control CPU 41a is in the ART mode (in the ART mode in which the add-on mode is not set) and the winning combination of the watermelon or cherry is instructed, the sub-control CPU 41a draws whether or not to shift to the add-on mode. Execute. The winning probability of the extra mode transition lottery when the winning of the cherry role is instructed is set to be higher than the winning probability of the extra mode transition lottery when the winning of the watermelon role is instructed. When the lottery is won, the sub-control CPU 41a determines to shift the effect state to the addition mode, and shifts the effect state to the addition mode from the change game or the change game after a predetermined number of times have passed.

  When the sub-control CPU 41a shifts to the addition mode, the sub-control CPU 41a interrupts the ART mode and controls the effect state to the first addition mode. At this time, the sub control CPU 41a sets a value indicating that the first addition mode is being executed in the first addition flag. Further, the sub-control CPU 41a interrupts the ART mode and continuously holds the number of remaining games in the ART mode even when the mode is shifted to the addition mode. Note that the sub-control CPU 41a resumes the ART mode with the number of remaining games at the time of interruption after the completion of all the addition modes.

  Then, the sub-control CPU 41a sets a value indicating that the addition mode is being executed only when one addition mode is being executed (that is, only one of the first addition flag and the second addition flag is set). In the case where it is displayed), a display image indicating that one addition mode is being displayed is displayed on the entire display area of the effect display device 14. Thereby, it can be easily recognized that one addition mode is executed in appearance.

Next, a description will be given of a parallel condition that is an execution trigger for executing the two addition modes in parallel and a process after the establishment of the parallel condition.
If the sub-control CPU 41a is instructed to win the watermelon or cherry role during execution of one addition mode (first addition mode or second addition mode), whether or not to execute the two addition modes in parallel A parallel lottery for lottering is executed. The winning probability of the parallel lottery when the winning of the cherry role is instructed is set to be higher than the winning probability of the parallel lottery when the winning of the watermelon role is instructed.

  When the lottery is won, the sub-control CPU 41a determines to execute the two additional modes in parallel, and executes the two additional modes in parallel from the variable game or the variable game after a predetermined number of times have passed. Let More specifically, when the first addition mode is being executed, the sub control CPU 41a executes the second addition mode together with the first addition mode. When the second addition mode is being executed, the sub control CPU 41a causes the first addition mode to be executed together with the second addition mode. In addition, it is determined from 0 to 3 times by lottery whether the two additional modes are executed in parallel in the changing game after winning the parallel lottery.

  In the present embodiment, when winning of a watermelon role or a cherry role is instructed during one addition mode, until two addition modes are executed in parallel or a predetermined number of variable games are executed. Until then, the prelude direction is executed. This sign production improves the player's expectation.

  Then, when the parallel condition is established during one addition mode and the sub control CPU 41a is executed in parallel with the two addition modes, a value indicating that the first addition mode is being executed is set to the first addition flag. And a value indicating that the second addition mode is being executed is set in the second addition flag. In the present embodiment, the establishment of the parallel condition corresponds to the establishment of the specific condition. In the present embodiment, the state in which values are set in the two additional flags corresponds to the state in which the establishment information is stored. The sub-control RAM 41c serves as a storage unit.

  Then, when the sub-control CPU 41a is executing two addition modes (that is, when a value indicating that the addition mode is being executed is set in the first addition flag and the second addition flag). The display area of the effect display device 14 is divided into two, and a display image indicating that the display mode is being added is displayed on each of the display areas. Thereby, it can be easily recognized that the two addition modes are executed in parallel.

  Then, the sub-control CPU 41a performs an execution process related to the addition mode based on the execution of the variable game, the winning of the winning combination, and the winning (or missing) instruction during the addition mode. A single execution process is executed when one addition mode is executed, and a parallel execution process is executed when two addition modes are executed in parallel.

First, the single execution process will be described.
When a value indicating that the addition mode is being executed is set only in one of the first addition flag and the second addition flag, the sub-control CPU 41a each time a variable game start command is input, It is determined whether or not the parallel condition is satisfied. Then, the sub-control CPU 41a executes a normal continuation lottery in which a lottery is performed to determine whether or not to continue the addition mode when the above-described parallel condition is not satisfied.

  The winning probability (normal continuation rate) in this normal continuous lottery is determined by lottery when execution of the extra mode is set (that is, when a value is set in the extra flag). In this embodiment, one of 50%, 60%, and 70% is determined. The determined normal continuation rate is stored in the storage area corresponding to the addition flag for which the value is set. That is, when the value is set in the first addition flag, the normal continuation rate determined in the storage area corresponding to the first addition mode is stored, and the value is set in the second addition flag. The normal continuation rate determined in the storage area corresponding to the second addition mode is stored. In addition, when one sign-up mode is being executed in response to an instruction to win a watermelon or cherry role in one extra mode, the normal continuous lottery must be won regardless of the normal continuation rate. .

  When the normal continuous lottery is lost, the sub-control CPU 41a deletes the value indicating that the addition mode is being executed from all the addition flags. Accordingly, various information (such as a reference number described later) stored in the storage area corresponding to the addition flag for which the value has been set is also deleted. If the value indicating that the addition mode is being executed is deleted from all the addition flags as a result of the normal continuous lottery, the sub control CPU 41a ends the addition mode and interrupts the ART mode. To resume.

  On the other hand, when the normal continuous lottery is won, the sub-control CPU 41a continues the addition mode. Further, the sub-control CPU 41a determines ART addition. In other words, in the present embodiment, the normal continuous lottery is added and has a role as a lottery. When the sub control CPU 41a determines the ART addition, the sub control CPU 41a determines the number of ARTs to be added to the number of remaining games in the ART mode.

  Here, according to FIG. 8, the normal number determination process executed when the normal continuous lottery is won in order to determine the number of ARTs (addition number) to be added to the remaining number of games in the ART mode will be described.

  First, it is determined whether or not it is the first (first) variable game from the ART mode to the addition mode (that is, whether or not a reference number described later has already been set) (step S101). If the determination result in step S101 is affirmative (if it is the first variation game after shifting to the addition mode), the sub-control CPU 41a is based on the variation game start command input for the first time after shifting to the addition mode. The first reference number is determined (step S102). The reference number (reference period) is the number of times added to the number of ARTs every time an extra lottery (continuous lottery) is won, and the number is increased (lengthened) every time the number of extra lotteries won is increased. At this time, the sub-control CPU 41a determines the first reference number with reference to the reference number setting table T11.

  As shown in FIG. 9, in the reference number setting table T11, a plurality of reference numbers that can be determined as the first reference number are set, and a random number value for determining the number of times to be distributed (random value) is assigned for each reference number that can be determined. Range) is set. The number-of-times determination random number is updated by the sub-control CPU 41a and stored in the sub-control RAM 41c.

  Accordingly, the sub-control CPU 41a refers to the reference number setting table T11, specifies the reference number to which the acquired value of the random number for number determination is assigned, and determines the specified reference number as the first reference number. In step S102, the sub-control CPU 41a stores the determined reference number in the sub-control RAM 41c in the storage area corresponding to the addition flag for which the value is set. That is, when a value is set in the first addition flag, the sub control CPU 41a stores the reference number determined in the storage area corresponding to the first addition mode in the sub control RAM 41c. Similarly, when a value is set in the second addition flag, the sub control CPU 41a stores the reference number determined in the storage area corresponding to the second addition mode in the sub control RAM 41c. Then, the normal number of times determination process ends.

  Next, processing in the case where the determination result in step S101 is negative, that is, processing when determining the number of times of addition in the second and subsequent variable games after shifting to the addition mode will be described.

  When the sub-control CPU 41a wins the normal continuous lottery in the second and subsequent variable games after shifting to the addition mode, the sub-control CPU 41a specifies the winning combination based on the variable game start command (step S103). Then, the normal addition tables T31 to T34 set for each winning combination are specified, and the number of increases is determined with reference to the specified normal addition tables T31 to T34 (step S104). The number of times of increase is the number of times that is added to the reference number of times determined until the previous variation game, and the number of times that the determined number of times of increase is added to the reference number of times until the previous time is determined as the new reference number of times. The reference number up to the previous time is specified by reading the reference number stored in the storage area corresponding to the addition flag for which the value is set.

  Also, as shown in FIGS. 10A to 10D, the normal addition tables T31 to T34 are set for each winning combination, and when the winning combination is other than the bell, watermelon and cherry roles, Normally, the extra table T31 is specified, and when the winning combination is won, the normal extra table T32 is specified. When the watermelon combination is won, the normal addition table T33 is specified, and when the cherry combination is selected, the normal addition table T34 is specified.

  In each of the normal addition tables T31 to T34, one or a plurality of increasing numbers are set, and a random number value for determining the number of times (range of random number values) is assigned to each increasing number. The sub-control CPU 41a refers to the specified normal addition tables T31 to T34, and determines the number of increase times to which the obtained number-of-times determination random number value is distributed. Then, the sub-control CPU 41a adds the determined number of increases to the previous reference number (step S105).

  Next, the sub control CPU 41a determines whether or not the added total number is less than the upper limit number (for example, 100 times) of the reference number (step S106). At this time, if the added total number is less than the upper limit number of the reference number (when the determination result of step S106 is affirmative), the sub control CPU 41a determines the added number as a new reference number (step S107). ). On the other hand, when the added number is equal to or greater than the upper limit number (when the determination result of step S106 is negative), the sub control CPU 41a determines the upper limit number as a new reference number (step S108). In step S107 or step S108, the sub control CPU 41a stores the determined new reference number in the sub control RAM 41c in the storage area corresponding to the addition flag for which the value is set, as described above. Then, the normal number of times determination process ends.

  Then, after the normal number determination process is completed, the sub-control CPU 41a stops displaying all the symbols (all the stop buttons 33 are operated) and inputs a winning instruction command, so that the sub-control CPU 41a corresponds to the added flag for which the value is set. The reference number stored in the storage area is determined as the additional number. When determining the number of times of addition, the sub-control CPU 41a informs the effect display device 14 of the determined number of times of addition, and adds it to the number of remaining games in the ART mode and stores it. Also, the number of remaining games after addition is notified.

Next, the parallel execution process will be described.
When the value indicating that the addition mode is being executed is set in the first addition flag and the second addition flag, the sub-control CPU 41a performs two addition modes each time a variable game start command is input. A special continuation lottery is executed to determine whether or not to continue.

  The lottery result of the special continuous lottery is determined based on the lottery result of the normal continuous lottery performed separately in the two extra modes. That is, when the normal continuous lottery in the first extra mode is won and the normal continuous lottery in the second extra mode is won, the special continuous lottery is won. On the other hand, if only one of them is lost, it is assumed that the player has lost the special continuous lottery. In addition, the continuation rate of the normal continuous lottery in each extra mode is determined by lottery when setting each extra mode. In this embodiment, one of 50%, 60%, and 70% is determined. The determined normal continuation rate is stored in the storage area corresponding to the addition flag for which the value is set.

  When the special continuous lottery is won, the sub-control CPU 41a continues to execute the two addition modes. Further, the sub-control CPU 41a determines ART addition for each addition mode. In the present embodiment, the special continuation lottery has a role as a lottery. When the sub control CPU 41a determines the ART addition, the sub control CPU 41a determines the number of ARTs to be added to the remaining number of games in the ART mode for each addition mode.

  Here, according to FIG. 11, a special number determination process executed when a special continuous lottery is won in order to determine the number of ARTs to be added (the number of additions) to be added to the number of remaining games in the ART mode will be described.

  First, the sub control CPU 41a determines whether or not the reference count up to the previous time is stored in the storage area corresponding to the first addition flag (step S201). If this determination result is negative, the sub control CPU 41a refers to the reference number setting table T11 and determines the first reference number (step S202). In step S202, the sub control CPU 41a stores the determined reference number in the sub control RAM 41c in the storage area corresponding to the first addition flag.

  On the other hand, if the determination result of step S201 is negative, the sub-control CPU 41a identifies the winning combination based on the variable game start command input as an execution trigger for the special continuous lottery (step S203). Then, similarly to step S104, the sub-control CPU 41a specifies the normal addition tables T31 to T34 set for each winning combination, and determines the number of increases by referring to the specified normal addition tables T31 to T34 (step S104). S204).

  Then, the sub control CPU 41a adds the determined number of increases to the reference number up to the previous time (step S205). Next, the sub control CPU 41a determines whether or not the added total number is less than the upper limit number (for example, 100 times) of the reference number (step S206). At this time, if the added total number is less than the upper limit number of reference times (when the determination result of step S206 is affirmative), the sub control CPU 41a determines the added number as a new reference number (step S207). ). On the other hand, when the added number is equal to or greater than the upper limit number (when the determination result of step S206 is negative), the sub control CPU 41a determines the upper limit number as a new reference number (step S208). In Step S207 or Step S208, the sub control CPU 41a stores the determined new reference number in the storage area corresponding to the first addition flag.

  Thereafter, similarly to the reference number stored in the storage area corresponding to the first addition flag, the reference number stored in the storage area corresponding to the second addition flag is updated to store the new reference number (steps S301 to S301). S308). The reference number updating method (steps S301 to S308) stored in the storage area corresponding to the second addition flag is determined by executing processing equivalent to the processing from steps S201 to S208 described above. Since the processing contents are the same as those described above, detailed description thereof is omitted.

  Then, after the special number determination process ends, all the symbols are stopped and displayed, and the sub-control CPU 41a inputs the winning instruction command, the reference number stored in the storage area corresponding to the first addition flag, and the second number The reference number stored in the storage area corresponding to the additional flag is determined as the additional number. When the sub-control CPU 41a determines the number of times of addition, the sub-control CPU 41a notifies the effect display device 14 of the determined number of additions. At the same time, the sub-control CPU 41a adds and stores the number of remaining games in the ART mode. Also, the number of remaining games after addition is notified. That is, in a single variable game, the total number of times of addition of the reference number stored in the storage area corresponding to the first addition flag and the reference number stored in the storage area corresponding to the second addition flag is one, It can be added and it can be made to think that the privilege was provided for every two addition modes.

Next, a case where the special continuous lottery is lost will be described.
If the special continuous lottery is lost, the sub control CPU 41a reads the reference number stored in the storage area corresponding to the first addition flag and the reference number stored in the storage area corresponding to the second addition flag. Then, the sub-control CPU 41a determines which reference number is greater. Then, the sub control CPU 41a deletes the large reference number at the end of the variable game and deletes the value from the addition flag corresponding to the storage area in which the large reference number is stored. That is, the addition mode corresponding to a large number of reference times ends. Further, various information (continuation rate and reference number) stored in the storage information corresponding to the addition flag for deleting the value is also deleted.

  As a result, the parallel operation of the two addition modes ends, and only one addition mode is executed. Also, only a small number of reference times is stored and held. Note that, in a variable game that has been lost in the special continuation lottery, the ART is not added by the addition mode that has not been deleted, and the reference number is not updated. Further, the sub-control CPU 41a finishes the division of the display area of the effect display device 14 and is in the one addition mode for the entire display area when the variable game is ended and one addition mode is set. A display image showing is displayed. As a result, it can be easily recognized that the parallel execution of the two addition modes is finished and the one addition mode is executed.

  In addition mode, the sub-control CPU 41a performs “bell navigation effect” in the same manner as in the preparation mode and the ART mode when the winning combination of the bell role whose stop mode changes depending on the pressing order of the stop button 33 among the small roles is instructed. The display content of the effect display device 14 is controlled so that For this reason, during the extra mode, an effect is performed so as to avoid the bell spill and assist the bell winning, and when the player performs the game according to the bell navigation effect, the bell spill is avoided and the bell winning is generated.

  Further, the sub-control CPU 41a controls the effect state so as to continue the addition mode when the bell winning is instructed. In this case, the high-reliability RT game is continued in the control state. In addition, when the bell spill is instructed, the sub-control CPU 41a controls the effect state so as to end the addition mode and shift to the preparation mode. In this case, the control state is shifted to the low probability RT game.

Next, according to FIG. 12, the addition mode of the number of times of addition will be described together with its operation.
In FIG. 12, description will be made on the assumption that the normal continuous lottery in the first to second variation games after winning the first addition mode from the ART mode is won. Further, in FIG. 12, the description will be made assuming that the watermelon stop eye is displayed in the third variation game, and the parallel lottery is won (the parallel condition is satisfied). Further, the description will be made on the assumption that the previous article production starts from the next variation game. In FIG. 12, description will be made assuming that the precursor effect is executed in the fourth to fifth variation games. Then, in FIG. 12, the description will be made on the assumption that two addition modes are executed in parallel in the sixth variation game. Further, in the sixth to seventh variation games, the explanation will be made assuming that the special continuous lottery is won. In the eighth variation game, it is assumed that the special continuous lottery is lost. In the ninth variation game, it is assumed that the normal continuous lottery is won. In addition, it is assumed that the remaining number of games is 30 at the start of the transition from the ART mode to the first extra mode.

  As shown in FIG. 12, since the normal continuous lottery in the first variation game is won based on the premise, the addition mode is continued in the second variation game. Further, it is determined that the reference number is added to the remaining number of games. For this reason, the first reference number is determined as an additional number and added to the remaining number of games. In the following description, it is assumed that 5 is determined as the first reference number. Therefore, 5 is added to the number of remaining games, and the number of remaining games is 35 (time point A1). Further, 5 times is stored as the reference number stored in the storage area corresponding to the first addition flag.

  Since the normal continuous lottery is won even in the second variation game from the premise, the addition mode continues in the third variation game. Further, it is determined that the reference number is added to the remaining number of games. In addition, it demonstrates as what determines 10 times as an increase frequency. Therefore, the new reference number is 15, and 15 is added to the remaining number of games, and the remaining number of games is 50 (time point A2). Further, 15 times is stored as the reference number stored in the storage area corresponding to the first addition flag.

  The parallel condition is satisfied in the third variation game from the premise. After the parallel condition is satisfied, the normal continuous lottery is won until the two additional modes are executed in parallel (until values are set in the two additional flags). For this reason, the addition mode continues in the fourth variation game. Further, it is determined that the reference number is added to the remaining number of games. In the following description, it is assumed that the number of increases is five. Therefore, the new reference number is 20, and 20 is added to the remaining number of games, and the remaining number of games is 70 (time point A3). Further, 20 times is stored as the reference number stored in the storage area corresponding to the first addition flag.

  Then, with the start of the fourth variation game from the premise, a precursor effect is executed (time point A4). During the sign production, since the normal continuous lottery is always won, the addition mode continues in the fifth variable game. Further, it is determined that the reference number is added to the remaining number of games. In the following description, it is assumed that the number of increases is five. Therefore, the new reference number is 25, 25 is added to the remaining number of games, and the remaining number of games is 95 (time A4). In addition, 25 is stored as the reference number stored in the storage area corresponding to the first addition flag.

  Similarly, the fifth variation game is executed from the premise. At this time, since the sign production is being performed, the normal continuous lottery is won, and the addition mode is continued in the sixth variation game. Further, it is determined that the reference number is added to the remaining number of games. In addition, it demonstrates as what determines 10 times as an increase frequency. Therefore, the new reference number is 35, 35 is added to the remaining number of games, and the remaining number of games is 130 (time A5). In addition, 35 is stored as the reference count stored in the storage area corresponding to the first addition flag.

  Then, in the sixth variation game, two addition modes are executed in parallel. As a result, values are set for both the first addition flag and the second addition flag (establishment information is stored). In addition, the display area of the effect display device 14 is divided, and display images related to the two addition modes are respectively displayed. In addition, since the special continuous lottery is won in the sixth variation game, two additional modes continue in the seventh variation game. Further, it is determined that the reference number is added to the remaining number of games for each extra mode.

  Here, a description will be given assuming that five times are determined as the number of increases added to the reference number corresponding to the first addition mode. Therefore, the reference number corresponding to the first addition mode is 40 times. Further, description will be made assuming that 10 is determined as the first reference number corresponding to the second addition mode. For this reason, 50 is added to the number of remaining games, and the number of remaining games is 180 times (time point A6). Then, 40 times is stored as the reference number stored in the storage area corresponding to the first addition flag. In addition, 10 is stored as the reference number stored in the storage area corresponding to the second addition flag.

  Also, since the special continuous lottery is won in the seventh variation game from the premise, the two additional modes continue in parallel in the eighth variation game. Further, it is determined that the reference number is added to the remaining number of games for each extra mode. Here, a description will be given assuming that 10 is determined as the number of increases added to the reference number corresponding to the first addition mode. Therefore, the reference number corresponding to the first addition mode is 50 times. Further, description will be made assuming that five times are determined as the number of increases added to the reference number corresponding to the second addition mode. For this reason, the reference number corresponding to the second addition mode is 15 times. For this reason, 65 is added to the number of remaining games, and the number of remaining games is 245 times (time A7). Then, 50 is stored as the reference number stored in the storage area corresponding to the first addition flag. Further, 15 times is stored as the reference number stored in the storage area corresponding to the second addition flag.

  Then, in the eighth variation game from the premise, the player is lost in the special continuous lottery. At this time, since the reference number (50 times) stored in the storage area corresponding to the first addition flag is larger than the reference number (15 times) stored in the storage area corresponding to the second addition flag, The reference number stored in the storage area corresponding to the first addition flag is deleted, and the value is deleted from the first addition flag. As a result, only the second addition mode is executed. The ART number is not added, and the remaining game number is maintained at 245 times.

  Since the normal continuous lottery is won in the ninth variation game from the premise, the second addition mode is continued in the tenth variation game. In addition, it is determined that the reference number corresponding to the second addition mode is added to the remaining number of games. In the following description, it is assumed that the number of increases is five. For this reason, the new reference number stored in the storage area corresponding to the second addition flag is 20, and 20 is added to the remaining number of games, and the remaining number of games is 265 (time A9). Further, 20 times is stored as the reference number stored in the storage area corresponding to the second addition flag.

  As described above, the longer the variable game is continued during the addition mode, the more the reference number becomes and the more the number of additions becomes. More specifically, the number of times that is surely greater than the previous reference number is added. In addition, when the two addition modes are executed in parallel, a reference number is set for each, and each reference number is added to the remaining number of games. For this reason, it is possible to add more when the two addition modes are executed in parallel than when the one addition mode is set. In addition, when the two addition modes are executed, the reference number increases, respectively. Therefore, as the number of times the two addition modes are executed in parallel increases, compared to the case where the one addition mode continues similarly. , You can add more. Further, when two extra modes are executed, even if the special continuous lottery is lost, the single extra mode is maintained, and the opportunity to perform ART extra can be maintained. On the other hand, if the normal continuation lottery or the special continuation lottery is lost, no ART is added. Therefore, the player can be interested in whether or not to win the continuous lottery and the winning probability (continuation rate) of the continuous lottery.

As described above in detail, the present embodiment has the following effects.
(1) If a value indicating that the addition mode is executed is set in the first addition flag and the second addition flag when the parallel condition is satisfied, even if the special continuous lottery is lost, the first The addition mode is continued only by deleting the value from one of the addition flag and the second addition flag. Therefore, pay attention to whether or not the parallel condition is satisfied, and if the parallel condition is satisfied, you can recognize that the addition mode will continue even if you lose the special continuous lottery, and enjoy the addition mode with confidence Can do. In addition, when the parallel condition is satisfied, the extra mode continues even if the special continuous lottery is lost, so that the extra mode can be enjoyed for a longer time, and the game period of the ART mode increases (extends) longer. Can be expected to be done.

  (2) The sub-control CPU 41a has a value in only one of the first addition flag and the second addition flag when the value is set in the first addition flag and the second addition flag during the addition mode. Opportunities to add ART more times than when set are increased. Specifically, the sub-control CPU 41a adds a reference number corresponding to one addition mode when only one addition mode is executed. On the other hand, when the two addition modes are executed in parallel, the sub control CPU 41a adds a reference number corresponding to each of the two addition modes. For this reason, when the parallel condition is satisfied, there are more opportunities to add ART, so that the gaming period of the ART mode can be increased in a short period. Therefore, when the parallel condition is satisfied, the player's interest can be further enhanced. In addition, since there are opportunities to be added many times, even if the number of additions on one side is small, it can be assumed that there is still an opportunity to increase the number of additions on the other side.

  (3) After it is determined that the two addition modes are executed in parallel, the sign effect is performed until the two addition modes are actually executed in parallel. During this sign production, the normal continuation production is won and the extra mode is continued. For this reason, when the parallel condition is satisfied, the addition mode is not terminated and the ART mode is not shifted to until the two addition modes are surely executed in parallel. Therefore, it is possible to relieve the player and concentrate on the whereabouts of the sign effect during the sign effect. On the other hand, since the two additional modes are not executed in parallel until the predetermined period elapses after the parallel condition is satisfied, the player is predicted when the two additional modes will be executed in parallel. Can be difficult. In addition, during the predetermined period, a sign effect that improves the player's expectation can be executed over a plurality of variable games, and the player can be entertained. In addition, since the precursor effect is executed when the specific role is won even if the parallel condition is not satisfied, it is possible to make the player expect that the two additional modes will be executed in parallel. .

  (4) Every time the number of times of winning the extra lottery (continuous lottery) increases, the reference number added when the extra lottery is won increases. For this reason, it can be noted about how many times the extra lottery is won. In other words, the more times the player wins the extra lottery, the more the player wants to win the extra lottery, and the greater the number of winners who win the extra lottery. Can do. Also, since the reference number is added only when the extra lottery is won, it can be noted whether or not the extra lottery is won every reference number. In addition, for each reference number corresponding to each addition flag, the reference number increases according to the number of winning of the corresponding addition lottery, so it can be noted how long the reference number is increased. In other words, when the two extra modes are executed in parallel, the number of extra lotteries won in the first extra mode and the extra lottery won in the second extra mode are different. Every time, the reference number of times can be noted. In addition, when the two addition modes are executed in parallel, a larger number of reference times (two reference times in the present embodiment) is set and the number of times is extended more than when not executed in parallel. There is a possibility that. For this reason, when the two extra modes are executed in parallel, attention can be paid to a larger number of reference times and the number of winning of the extra lottery corresponding to each reference number.

  (5) When the execution of the two addition modes in parallel ends, the smaller reference number of the two reference numbers is maintained even if it becomes one addition mode. For this reason, it is possible to clearly add the number of times of addition when the two addition modes are executed in parallel and when the one addition mode is executed. Further, since a small reference number is stored and held, the process of increasing the reference number can be enjoyed again.

  (6) During the extra mode, every time the number of wins for the extra lottery (also used as a continuous lottery) increases, the reference number added to the remaining number of games when the extra lottery is won increases. For this reason, it can be noted about how many times the extra lottery is won. Therefore, whether or not the extra lottery can be executed, whether or not the extra lottery has been won is not paid attention to only the number of additions in one variable game, and the interest in adding the ART number can be improved. In other words, the more times the player wins the extra lottery, the more the player wants to win the extra lottery, and the greater the number of winners who win the extra lottery. Can do.

  (7) The continuous lottery also serves as an extra lottery, and when the continuous lottery is won, the extra lottery is won. For this reason, as long as the continuous lottery (the extra lottery) continues to be won, the extra mode in which the continuous lottery is performed continues. Further, as long as the continuous lottery continues to be won, the reference number added to the ART number at the time of winning is also increased. For this reason, it is possible to make the player pay more attention to how long the extra mode continues (that is, whether or not to win the continuous lottery) and the continuation rate. And as the period in which the extra mode continues is longer, more attention can be paid to whether or not the extra lottery is won, and the interest of the game is improved.

  (8) The reference number (reference period) that is added every time the winning lottery is won increases (longer) as the number of winning points for the extra lottery increases. For this reason, it is possible to expect that the ART mode is extended by adding a minimum number of times more than the reference number added last time and extending the ART mode.

(Second Embodiment)
Next, a second embodiment embodying the present invention will be described. The same configurations as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and detailed description and drawings thereof are omitted or simplified.

  In the second embodiment, in the extra mode, the normal continuation rate of the normal continuous lottery is configured to increase every time the continuous lottery is won. Hereinafter, the normal continuous lottery will be described in detail.

  When the sub-control CPU 41a executes the normal continuous lottery, if the continuation rate is not set in the storage area corresponding to the additional flag for which the value has been set (for example, the first time when shifting from the ART mode to the first additional mode) A predetermined initial probability (for example, 30%) is set. And when a continuous lottery is won, the initial probability is stored as a reference probability.

  In addition, when the continuation rate is set in the storage area corresponding to the additional flag for which the value is set (for example, in the second transition game after shifting to the additional mode), The control CPU 41a determines the continuation rate in the current normal continuation lottery based on the continuation rate (reference probability) in the previous normal continuation lottery. Note that the continuation rate in the current normal continuation lottery is set to be higher than at least the reference probability (previous continuation rate). Specifically, the normal continuous lottery is executed with a probability 5% higher than the previous continuation rate. For example, when the previous continuation rate is 50%, the normal continuation lottery is executed with a winning probability of 55%. Note that an upper limit is set in advance for the continuation rate, which is 90% in the present embodiment. The sub-control RAM 41c stores the new continuation rate (winning probability in the current continuous lottery) as a new reference probability in the sub-control RAM 41c.

  When the normal continuous lottery is won, the sub-control CPU 41a continues the addition mode as described above. On the other hand, if the lottery is lost, the sub-control CPU 41a ends the addition mode and restarts the interrupted ART mode. The special continuation lottery is also configured to improve the continuation rate.

As described above in detail, the present embodiment has the following effects.
(10) In the extra mode, the winning probability (continuation rate) of the continuous lottery increases every time the number of times of winning the continuous lottery increases. For this reason, it can be noted about how many times the continuous lottery is won. Accordingly, attention is not paid only to whether or not the continuous lottery can be executed and whether or not the continuous lottery is won, and the more the lottery is repeated, the more the fun can be improved. In other words, the higher the number of wins in the continuous lottery, the higher the continuation rate and the more advantageous to the player. More attention can be given to whether or not the winner is won, and interest can be improved.

In addition, the said embodiment can be actualized in another embodiment (another example) as follows.
In the above embodiment, the continuous lottery also serves as the extra lottery, but the continuous lottery and the extra lottery may be performed in different lotteries. That is, while the addition mode is continued, the ART addition may not be performed, and the addition mode may be terminated while the ART addition may be performed. Further, the winning probabilities of the continuous lottery and the extra lottery may be different. When the continuous lottery and the extra lottery are performed in different lotteries, when the two extra modes are executed in parallel, the extra lottery may be executed for each extra mode. Then, the reference number for each extra mode may be increased individually when the extra lottery is won for each extra mode. Thereby, it becomes easy to recognize that the addition mode is individually executed.

-In the said embodiment, you may change a specific combination arbitrarily. For example, a bell role may be included in the specific role, or only a cherry role may be included.
In the above embodiment, the table for determining the number of increases to be added to the reference number (that is, the determination method) is different depending on the winning combination, but the same may be used.

  In the above embodiment, the table for determining the number of increases to be added to the reference number (that is, the determination method) is varied depending on the winning combination, but it may be varied depending on the winning stop.

  In the above embodiment, the initial reference number is determined in the same way regardless of the winning combination, but the determination probability of each reference number and the determined reference number may be different depending on the winning combination. Further, a predetermined number of times may be set according to the winning combination. Further, a predetermined number of times may be set as the first reference number.

In the above embodiment, the upper limit number of reference times is set, but it may not be set. Further, the upper limit number may be arbitrarily changed.
In the above embodiment, the continuous lottery is performed during the addition mode, but it may not be performed. In this case, the extra mode may be executed for a predetermined number of games.

In the above embodiment, the number of additional additions may be determined at the time of winning a specific combination, and further added to the number of additions.
-In the said embodiment, you may change arbitrarily the content of the transition condition used as the transition opportunity of the addition mode. For example, the special replay combination can be won, and the transition condition may be satisfied when the special replay combination wins. Alternatively, a lottery may be performed for each variable game, and the transition condition may be satisfied when the game is won.

  -In the said embodiment, you may change arbitrarily the completion | finish opportunity of addition mode. For example, the addition mode may be ended when a predetermined number of fluctuating games are executed, and may be ended when the ART addition number becomes equal to or more than a predetermined number.

In the above embodiment, a bonus game (bonus game) in which the winning probability of a bell role or the like is greatly increased as compared to a general game may be provided.
In the embodiment described above, a specified number of times indicating the number of times that the variable game is played until the ART mode is set may be provided.

In the above embodiment, the sub-control CPU 41a may or may not execute the bell navigation effect during the preparation mode.
In the above embodiment, the sub control CPU 41a gives a privilege, but the main control CPU 40a may determine and grant the privilege content.

  In the above embodiment, the number of times that the variable mode to which the ART mode is given is added, but a period that is a unit of the ART mode may be added. The period that is the unit of the ART mode may be, for example, when one set (one unit) is 10 games and the winning lottery is won, and one set may be added. Similarly, the number of sets to be added may be increased according to the number of winning lotteries.

  In the second embodiment, the initial probability is a predetermined probability, but may be determined by lottery from a plurality of probabilities. The initial probability may be determined according to the winning combination or the winning stop. Further, the method for determining the initial probability may be changed according to the winning combination or the winning stop.

In the second embodiment, each time the continuous lottery is won, the reference number is increased, but it may not be increased.
In the second embodiment, the continuation rate of the continuous lottery in the transition game of the second transition after the transition to the addition mode has been drawn with a probability higher by a predetermined probability than the continuation rate (reference probability) in the previous continuous lottery. If the probability is higher than the reference probability, the continuation rate in the current continuous lottery may be arbitrarily determined. For example, how much the continuation rate is increased by lottery may be determined. That is, the reference probability may be increased by a probability determined from 5 to 10%.

  In the second embodiment, the rate of increase in the continuation rate of the normal continuous lottery may be different from the rate of increase in the continuation rate of the special continuous lottery. For example, the continuation rate of the special continuation lottery may be increased.

  In the above embodiment, the contents of the transition condition and the parallel condition may be the same or different. For example, the transition lottery is executed only when the watermelon role is won, and the transition condition is established when the transfer lottery is won, while the parallel lottery is executed only when the cherry role is won, The parallel condition may be satisfied when the lottery is won. Further, the winning probabilities of the transfer lottery and the parallel lottery may be different.

  In the above embodiment, when the two addition modes are parallel, the reference number is added as the addition number for each addition mode, but only one of them may be added.

  In the above embodiment, even when the two addition modes are in parallel, the reference number may be only one. In this case, the type of increase count that can be determined and the determination rate may be changed.

  In the above embodiment, when the two addition modes are in parallel, the reference number is set for each addition mode. However, two or more reference numbers may be set and added as the addition number.

  -In the above embodiment, when the special continuous lottery was lost, the remaining number of games was not added, but even if the special continuous lottery was lost, there was an extra mode that won the normal continuous lottery When doing so, the reference number corresponding to the extra mode may be updated and added to the remaining number of games.

  In the above embodiment, when it is determined that the two addition modes are executed in parallel, the precursor effect is executed, but it may not be executed. In addition, during the sign production, the normal continuous lottery is always won, but it may be lost.

  -In the above embodiment, when the two additional modes are executed in parallel, each of the normal continuous lotteries is executed, and the result of the special continuous lottery is determined based on the results of the two normal continuous lotteries. A continuation rate of the special continuation lottery may be determined, and whether or not to win in one lottery may be drawn.

  -In the above embodiment, when two normal addition lottery modes are executed in parallel, when each of the normal continuous lotteries is executed, if any one of the normal continuous lotteries is lost, the lost addition mode is selected. You may make it complete | finish. At this time, the reference number corresponding to the selected extra mode is also deleted. Further, when both are lost at the same time, only one of the addition modes (for example, the addition mode with a large number of reference times) may be terminated.

  In the above embodiment, when the special continuous lottery is lost and one extra mode is restored, the one with the smaller reference number is erased, but the one with the larger reference number may be erased. Further, the addition mode with a low continuation rate may be terminated.

Next, a technical idea that can be grasped from the above embodiment and another example will be added below.
(A) In the above gaming machine, the game control means performs a first extra lottery when the establishment information is not stored during the special gaming state, and when the first extra lottery is won, the first reference period Is added, the period of the advantageous gaming state to be given is increased, and when the establishment information is stored during the special gaming state, the first extra lottery and the second extra lottery are performed, and the first extra lottery is performed. When winning, the first reference period is added. When the second extra lottery is won, the second reference period is added. When both the first extra lottery and the second extra lottery are won, the first reference period is added. By adding both the reference period and the second reference period, the period of the advantageous gaming state to be given is increased, so that the first reference period becomes longer as the number of times of winning the first extra lottery increases. Configured, Serial second reference period may be constituted to be longer each time the number of times of winning the second plus drawing increases.

  (B) In the above gaming machine, the game control means loses the continuous lottery when the establishment information is stored during the special gaming state, and when the establishment information is erased, The reference period other than the short reference period may be deleted, and the setting of the reference period other than the shortest reference period may be terminated.
