Description

As a medal increase period in a slot machine, conventionally, a bonus game and an assist replay time (hereinafter referred to as ART) are known.
Among these, the bonus game is started based on the winning of the bonus combination after the internal winning of the bonus combination. According to the rules relating to gaming machines, the bonus game is defined to end when the number of medals acquired during the bonus game exceeds a threshold value.
In addition, the rules related to gaming machines have an upper limit on the ratio of the number of medals earned per unit time through the bonus game (hereinafter referred to as the “role ratio”). The probability and the threshold value need to be set in consideration of the accessory ratio. For this reason, the bonus game does not continue for a long time.

  On the other hand, there is no stipulation on the end condition related to the number of medals earned during ART in the rules related to gaming machines, and the number of medals earned during ART is not earned through the bonus game, so it has an effect on the increase in the ratio of bonuses There is a merit in improving the shooting property that does not give. For this reason, in recent years, a slot machine (hereinafter referred to as an ART machine) having a game characteristic in which ART is more important than a bonus game is generally used as a medal increase period (see Patent Document 1).

  On the other hand, there has been a demand for a gaming machine having an appropriate shooting ability as a countermeasure against the problem of “reluctant”, and the gaming machine industry is currently in a relatively advantageous state for players including ART and bonus games. The introduction of a limiter function that forcibly terminates the advantageous state (hereinafter referred to as the advantageous state) for a certain period or longer has been studied. Specifically, the limiter function forcibly ends the advantageous state when the number of continuous games in a series of advantageous states or the number of medals acquired during a series of advantageous states exceeds a predetermined limit value. It is to let you.

  By the way, the conventional ART machine has a game number management type that manages the ART period based on the number of remaining games, a set number management type that manages the ART period based on the remaining set number, and a combination of the game number management type and the set number management type. There are three main types: composite type.

  Of these, in a game number management type (including complex type) ART machine, it is common to perform an extra lottery to add the number of remaining games of ART during ART. In addition, it is common to determine the winning probability of the extra lottery and the expected extra value according to the result of the internal lottery process for determining the winning combination that is executed every game. In the slot machine, an internal lottery process is performed in response to a game start operation (start lever operation). Therefore, the above-described general method of performing an extra lottery according to the result can determine the result of the extra lottery at the start of the game. There are benefits. Further, since the reel stop control is also executed in accordance with the internal lottery result, there is an advantage that the reel stop appearance and the expected degree of the lottery can be associated with each other.

  However, when the limiter function is simply introduced into the conventional ART machine adopting the above-described general addition lottery method, a large number of remaining games of the ART will remain when the limiter function is activated. It is inevitable to give the player a sense of loss.

  Similarly, in the above-mentioned set number management type (including complex type) slot machines, for each set, it is common to determine whether to start the next set or whether to increase the number of sets. Thus, for example, in Patent Document 2, a continuous lottery to the next set is performed at a predetermined continuation rate for each set, and the continuation rate of the next set is determined according to the continuation rate of the previous set. A technique for changing the rate for each set is disclosed.

JP 2014-23648 A JP2013-169285A

  However, when introducing the limiter function into the above-mentioned general conventional ART machine, the number of games remaining in the ART remains large when the limiter function is activated in the game number management type, and the limiter function is set in the set number management type. Since a large number of remaining ART sets during operation will result in a loss of feeling to the player, a device for avoiding this situation is required.

  Therefore, an object of the present invention is to provide a slot machine that can suppress a feeling of loss given to a player when reaching a limiter.

  When the medal acceptance / impossibility display LED 12 is lit, if a medal is inserted from the medal insertion slot 16, the insertion is accepted. While the medal acceptance / prohibition display LED 12 is turned off, even if a medal is inserted from the medal insertion slot 16, the insertion is not accepted, and a medal is placed on the medal tray 23 from the medal discharge opening 22 provided at the bottom of the front door 3. Discharged.

  When a medal to be used for the game is not betted and a medal insertion is accepted, the medal is bet on the game, and one bet number display LED 9 is turned on. Subsequently, when a medal is inserted from the medal insertion slot 16, a second medal is additionally bet on the game, and the two bet number display LEDs 9 are lit. Further, when a medal is inserted from the medal insertion slot 16, the third medal is additionally bet on the game, and the three bet number display LEDs 9 are lit. In the slot machine 1, when a specified number of medals is bet for one game (one game at a time), one game can be started, and the start possibility display LED 11 is lit. In addition, a predetermined pay line set in the reel window 6 is validated. When medals are inserted from the medal insertion slot 16 in a state where a prescribed number of medals are bet on the game, the inserted medals are credited to the slot machine 1 up to 50. The number of credited medals is displayed on the credit number display CR. When a medal is inserted from the medal insertion slot 16 with 50 medals being credited, the inserted medal is discharged from the medal discharge slot 22 to the medal tray 23.

  When a predetermined number or more of medals are credited to the slot machine 1 and no medals are bet on the game, when the MAX bet button 17 is operated, a predetermined number of medals are added to the game from the credited medals. A bet is placed, the three bet number display LEDs 9 and the start possibility display LED 11 are turned on, and a predetermined pay line set in the reel window 6 is activated.

  FIG. 3 is a block diagram showing an electrical configuration of the slot machine 1.

  The slot machine 1 includes a main control device 31 that performs central control of the game, a sub control device 32 that executes control for effects accompanying the game, and a liquid crystal control device 33 that controls the liquid crystal display device 24. It has.

  The main control device 31 includes a CPU 41, a ROM 42, a RAM 43, an input / output port 44, and a data transmission circuit 45. The CPU 41, the ROM 42, the RAM 43, the input / output port 44, and the data transmission circuit 45 are connected by a bus so as to communicate data. In addition, the main control device 31 is provided with a clock generation circuit 46 that supplies clock pulses to the CPU 41 and a random number generation circuit 47 that generates random numbers.

  The CPU 41 executes a program stored in the ROM 42 and controls each control target connected to the input / output port 44 based on a signal input from the input / output port 44.

  The RAM 43 is used as a work area when the CPU 41 executes a program.

  An input / output port (input port) 44 includes a MAX bet button 17, a single bet button 18, a start lever 19, a left stop button 20L, a middle stop button 20C, a right stop button 20R, a settlement button 21, and a left reel position detection sensor. 51L, a middle reel position detection sensor 51C, a right reel position detection sensor 51R, a medal insertion sensor 52, and a medal payout sensor 53 are connected.

  The input / output port (output port) 44 includes a credit amount indicator CR / instruction monitor NM, an advantageous state lamp YL, a payout amount indicator 8, a bet amount indicator LED 9, a replay indicator LED 10, a start availability indicator LED 11, and a medal acceptance availability indication. The LED 12 is connected as a control target. The input / output port (output port) 44 includes a left reel drive motor 61L that rotates the left reel 4L, a middle reel drive motor 61C that rotates the middle reel 4C, and a right reel drive motor that rotates the right reel 4R. 61R, a medal block solenoid 62 for switching acceptance / rejection of medals inserted from the medal insertion slot 16, and a medal payout drive motor for paying out medals from a medal storage section (not shown) provided in the main body 2 63 is connected as a control target.

  When the MAX bet button 17, the single bet button 18, the start lever 19, the left stop button 20L, the middle stop button 20C, the right stop button 20R, and the checkout button 21 are operated, the switches or sensors provided individually for them are operated. A signal is output, and the signal is input to the CPU 41 via the input / output port 44. Each time the left reel 4L, middle reel 4C and right reel 4R make one rotation, signals are output from the left reel position detection sensor 51L, middle reel position detection sensor 51C and right reel position detection sensor 51R, respectively. The data is input to the CPU 41 via the input / output port 44. Each time a medal is inserted from the medal insertion slot 16, a detection signal is output from the medal insertion sensor 52, and the detection signal is input to the CPU 41 via the input / output port 44. Each time the medal payout drive motor 63 is driven and a medal is paid out from the medal storage unit, a signal is output from the medal payout sensor 53, and the signal is input to the CPU 41 via the input / output port 44.

  Stepping motors are employed as the left reel drive motor 61L, the middle reel drive motor 61C, and the right reel drive motor 61R. When the start lever 19 is operated after a specified number of medals are bet on the game, the CPU 41 inputs drive pulse signals to the left reel drive motor 61L, the middle reel drive motor 61C, and the right reel drive motor 61R, and the left The rotation of the reel 4L, the middle reel 4C, and the right reel 4R is started. The CPU 41 outputs output signals of the left reel position detection sensor 51L, middle reel position detection sensor 51C and right reel position detection sensor 51R, and drive pulse signals to the left reel drive motor 61L, middle reel drive motor 61C and right reel drive motor 61R. Based on the number of outputs, the rotational positions of the left reel 4L, middle reel 4C, and right reel 4R are always grasped.

  Further, when the start lever 19 is operated, the CPU 41 executes an internal lottery. Specifically, the CPU 41 acquires a random number from the random number generation circuit 47 at the timing when the start lever 19 is operated. Then, the CPU 41 refers to the lottery table stored in the ROM 42. In the lottery table, a range of random numbers (for example, 0 to 65535) generated by the random number generation circuit 47 is divided into a plurality of lottery sections, and one or more roles are associated with each lottery section. The CPU 41 determines the winning combination corresponding to the lottery classification to which the random number acquired from the random number generation circuit 47 belongs as the winning combination. In addition, when the random number acquired from the random number generation circuit 47 does not belong to any lottery category, the CPU 41 determines that the result of the internal lottery is unfair (pure loss).

  Thereafter, when the rotation speeds of the left reel 4L, middle reel 4C and right reel 4R become constant, the CPU 41 activates the left stop button 20L, middle stop button 20C and right stop button 20R. When the left stop button 20L, middle stop button 20C, and right stop button 20R are operated, the CPU 41 determines the timing at which the left stop button 20L, middle stop button 20C, and right stop button 20R are operated, and the result of the internal lottery. Based on the above, output of drive pulse signals to the left reel drive motor 61L, middle reel drive motor 61C and right reel drive motor 61R is stopped, and the stop of the left reel 4L, middle reel 4C and right reel 4R is controlled. At this time, the rotation of the left reel 4L is stopped within the pull-in range in which the symbols corresponding to the predetermined number of frames move with reference to the rotation position of the left reel 4L at the timing when the left stop button 20L is pressed (retraction control). ). The same applies to the middle reel 4C and the right reel 4R.

  Then, the CPU 41 determines whether a combination of symbols corresponding to the winning combination in the internal lottery is arranged on the active line. If there is a combination of symbols corresponding to the winning combination on the active line, the CPU 41 determines that the winning combination is a winning combination, and executes processing according to the winning combination.

  Further, the CPU 41 sends various data to the sub control device 32 via the data sending circuit 45. The various data includes a bet signal indicating that the game start condition is satisfied, a lever on signal indicating that the start lever 19 has been operated, a left stop signal indicating that the left stop button 20L has been operated, and a middle stop button 20C. Stop signal indicating that the right stop button 20R has been operated, data relating to the results of the internal lottery and AT lottery, and the left stop button 20L, the middle stop button 20C and the right stop Instruction data for instructing the operation order of the button 20R is included.

In the slot machine 1, when a predetermined lottery condition is satisfied during the normal state where the advantageous state lamp YL shown in FIG. 2 is turned off, the advantageous state lamp YL shifts to an advantageous state where the advantageous state lamp YL is turned on. Whether or not the advantageous state transition lottery is performed is determined, and the advantage state is entered on condition that the advantageous state transition lottery is won.

<First embodiment>
<1. Normal state>
FIG. 11 shows the flow of game processing during the normal state.
First, an internal lottery process is executed in step S1101, and an advantageous state shift lottery process is executed in the next step S1102 in accordance with the result of the internal lottery process. The concrete lottery contents of the advantageous state transition lottery process are shown in FIG.
As shown in FIG. 12A, in the advantageous state transition lottery process, as a result of the internal lottery process in the normal state, the lottery group GRP1 (BB role), GRP2-13, GRP14 (cherry), or GRP18-20 is selected. The game is executed only in the winning game, and is skipped in the game won in the lottery group GRP15-17 and the game lost. Even during the normal state, the advantage state lottery process is not executed during the RT3 and BB games inside the bonus.

  The winning probability in the advantageous state transition lottery process is 10% for a game won in the lottery group GRP1, 1% for a game won in any of the lottery groups GRP2 to 13, and in a game won for the lottery group GRP14 (Cherry). In the game that has won 20% and one of the lottery groups GRP18 to 20, it is set to 30%.

When winning in the advantageous state shift lottery process, the lottery of the initial number of games is performed next.
FIG. 12B shows a lottery method for the initial number of games. The initial number of games is 30 games with a 90% allocation rate, 60 games with a 9% allocation rate, and 100 games with a 1% allocation rate. It is said.

  Returning to FIG. 11, in the next step S <b> 1103, it is determined as a result of the advantageous state transition lottery process whether or not the player has won. If YES is determined in step S1103, the process proceeds to the advantageous state process in step S1104 and the normal state process is terminated. If NO is determined, the process returns to step S1101.

<2. Advantageous state>
FIG. 13 shows the flow of the game process during the advantageous state.
First, in step S1301, the advantageous state lamp YL is turned on, the advantageous number of games is set to zero, and the number of remaining games is set to the initial number of games determined in the advantageous state transition lottery process.

In the next step S1302, an internal lottery process is executed. In response to this, in the next step S1303, 1 is added to the number of advantageous games and 1 is subtracted from the remaining number of games.
In the next step S1304, it is determined whether or not it is RT3 (inside bonus), and if it is determined to be no, in the next step S1305, the remaining number of games is added and a lottery process is executed, whereas if it is determined to be yes In step S1305, the process skips step S1305 and proceeds to step S1306.

FIG. 14 shows the details of the lottery process for adding the remaining number of games.
In the remaining game number addition lottery process, the winning probability and the number of additional games are set according to the internal lottery result, the current advantageous game number and the remaining game number.
Specifically, as the number G of additional games that can be added, which is a value obtained by subtracting the current number of advantageous games and the number of remaining games from 1500, which is the upper limit value of the number of advantageous games forcibly terminating the advantageous state, is reduced. Thus, the number of remaining games is added to reduce the winning probability in the lottery process.

  Here, the number G of games that can be added is a value obtained by subtracting the number of remaining games that have been given from the number of remaining games until the limiter function is activated (= 1500−the number of advantageous games). The upper limit value of the number of games that can be added at the current time when the number of remaining games that will never remain is assumed.

  In addition, when the lottery process with the remaining number of games is won, as a result of the internal lottery process, an additional number of remaining games corresponding to the minimum number of additional games set according to the type of the selected lottery group is “as much as possible. "It is a specification to do.

FIG. 14A shows the extra priority and the minimum extra game number set for each type of the lottery group that has won.
First, the addition priority will be described.
In the present embodiment, an extra priority is set for each of a plurality of types of lottery groups GRP1, GRP14, and GRP18 to 20 for which a minimum extra game number is set. Specifically, the top priority is set to the highest in the lottery group GRP1, the next highest in the lottery group GRP14, and the lowest in the lottery groups GRP18 to 20.

In the slot machine 1 of the present embodiment, since it is assumed that the remaining number of games is controlled so that the remaining number of games does not remain when the limiter is operated, for example, the lottery group GRP1 having the highest priority for addition In order to guarantee the addition of the minimum 50 additional games among the games won in the above, the number of games G that can be added is 50 or more.
Similarly, the minimum number of games to be guaranteed in the game selected to win the lottery group GRP14 with the next highest priority, and the minimum number of games to be added to the next lottery group GRP14 with the highest priority added to the lottery group GRP1 with the highest priority added. In order to guarantee the addition of 30 games, the number of games G that can be added is 80 or more, and in addition to this, in the game that won the lottery group GRP18-20 having the lowest priority for addition, the minimum number of games to be added is 10 games. In order to guarantee the addition, the number G of games that can be added is 90 or more.

  As described above, in the situation where the number G of additional games that can be added is small, if the minimum number of additional games corresponding to the selected lottery group is added, then if any of the lottery groups is won, the minimum number of additional games It may not be possible to guarantee the addition of. In such a case, processing for forcibly setting the winning probability of the lottery process for the number of remaining games to be set to zero is performed in order from the lottery group having the lowest priority for addition.

FIG. 14B shows the winning probability in the lottery process for adding the remaining number of games for each lottery group and the number of games that can be added.
Regarding the lottery group GRP1 with the highest priority for addition, the winning probability in the additional lottery process for the remaining number of games is 10% when the number of games that can be added is 50 or more, and when the number of additional games is less than 50, the minimum number of additional games is 50 games. Since the addition cannot be guaranteed, it is forcibly set to 0%.
Next, regarding the lottery group GRP14 with the highest priority for addition, the winning probability in the additional game number addition lottery process is 20% when the number of games that can be added is 80 or more, and if it is less than 80, the minimum number of games to be added 30 If a game is added, it is not possible to guarantee the addition of 50 minimum games when the lottery group GRP1 having a higher priority than the lottery group GRP14 is won. Therefore, the game is forcibly set to 0%.
Regarding the lottery groups GRP18 to 20 having the lowest priority for addition, the winning probability in the additional game number addition lottery process is 30% when the number of games that can be added is 500 or more, and 5% when the number of games that can be added is less than 500 and 90 or more. In the case of less than 90, if a minimum additional game number of 10 games is added, a minimum additional game number of 50 games and 30 games will be added when the lottery group GRP1 and the lottery group GRP14 having higher priority than the lottery group GRP14 are selected. Since it is not possible to guarantee the addition of 0, it is forcibly set to 0%.

  By adopting such additional control, if there is a surplus in the number G of games that can be added (the number of games that can be added G ≧ 90), the remaining number of games will be added when the winning lottery process is won. Remaining games in a situation where the number of additional games G that can be added is not enough (G <90), while guaranteeing the addition of the minimum number of additional games set for each lottery group (role) that triggers the lottery Even if you win the lottery process with extra numbers, among the lottery groups (parts) that will trigger the lottery with the remaining number of games, the lottery group (participant) with the higher priority will be selected as much as possible. It is possible to guarantee the addition of the minimum number of games set for each).

  Further, in this embodiment, when the number of games that can be added G has a margin (the number of games that can be added G ≧ 90), when the remaining number of games is added to the lottery process, Since there are cases where the number of remaining games is increased more than the minimum number of additional games set for each lottery group (role), the expected value of the actual number of additional games is larger than the minimum number of additional games.

  FIG. 14C shows the expected value of the additional number of games when the remaining number of games is added to the lottery process. From FIG. 14 (c), the expected value of the number of additional games decreases step by step as the number G of additional games that can be added decreases. It can be seen that the addition of the minimum additional game number set for each lottery group (role) is guaranteed.

  Returning to FIG. 13, in the next step S1306, it is determined whether or not the lottery groups GRP2 to 13 are won. If it is determined that the answer is yes, it is determined whether or not the user is staying at RT0 in step S1307. If it is determined NO in step S1307, the correct push order is notified in the next step S1308 and the process proceeds to step S1309. If YES is determined, that is, if the user is staying at RT0, In order to shift to RT1, step S1308 is skipped and the process proceeds to step S1309. Also when it is determined NO in step S1306, the process proceeds to step S1309.

In step S1309, it is determined whether or not the lottery groups GRP15 to 17 have been won. If the determination is yes, it is determined in step S1310 whether or not the user is staying at RT1. If it is determined as YES in step S1310, in the next step S1311, the correct pressing order is notified so as to shift to RT2, and the flow shifts to step S1312.
When it is determined NO in step S1309 and when NO is determined in step S1310, the process also proceeds to step S1312.

  In step S1312, it is determined whether or not the lottery groups GRP18 to 20 have been won. If the answer is yes, it is determined in step S1313 whether or not the lottery process for the remaining number of games executed in step S1305 has been won. Judging. If it is determined as YES in step S1313, the correct answer pressing order is notified in step S1314. If NO is determined, a pressing order other than the correct pressing order is notified in step S1315, and the process proceeds to step S1316. Transition.

In step S1316, it is determined whether or not the number of advantageous games has reached a limit value of 1500. If NO, it is determined in next step S1317 whether or not the remaining number of games has reached zero. If NO is determined in step S1317, the process returns to step S1302 to continue the advantageous state.
On the other hand, if YES is determined in step S1306 and YES is determined in step S1307, an advantageous state end process is executed in step S1318 to end the advantageous state, and in next step S1319. The process is terminated after shifting to the normal state process.
Specifically, in the advantageous state end process, an advantageous state lamp YL is turned off, and an area on the RAM 43 in which various variables relating to the control during the advantageous state are stored is performed.

  As described above, in the slot machine 1, as shown in FIG. 14B, in the advantageous state, in the game won in the lottery group GRP18-20, whether or not the number G of games that can be added is 90 or more, In addition to the remaining number of games, the winning probability of the lottery is changed from 30% to 0%.

Here, the lottery groups 18 to 20 are lottery groups in which the types of replay roles to be won are different depending on the operation order of the stop buttons 20L, 20C, and 20R, that is, the outcomes when all reels 4L, 4C, and 4R are stopped are different. is there.
As described above, in this slot machine 1, when the lottery groups 18 to 20 are added and adopted as the lottery trigger, and the number of games is added and the lottery is won, the correct game game 6 (watermelon RP) will win. The order of pressing is notified, and if the player loses the game, the re-game player 1 (normally RP) will win, and the operating order other than the correct pressing order will be notified.

  As a result, when the re-gamer 6 (watermelon RP) wins the player, the remaining game is always added, while when the re-gamer 1 (normal RP) wins, the remaining game Since it is possible to recognize that the addition of is not executed, the player notices that such a specification is adopted, although the specification that reduces the winning probability according to the number G of games that can be added is adopted. There is no fear.

<Second embodiment>
Hereinafter, the second embodiment will be described, but only the portions different from the first embodiment will be described, and the description of the same portions will be omitted.
As described above, the slot machine 1 according to the first embodiment relates to a so-called game number management type ART machine that ends an advantageous state when the number of remaining games becomes zero during the advantageous state.
On the other hand, the slot machine 1 according to the third embodiment is a so-called set continuation type ART machine that determines whether or not to start the next set for each set, with an ART game period of a predetermined length as one set. It is related to.

<1. Normal state>
In the normal state, although the processing content when winning the advantageous state transition lottery process is different from the first embodiment, the game process flow is the same as in the first embodiment, so the description is omitted. With reference to FIG. 15, processing contents when winning the advantageous state transition lottery processing will be described.

In the second embodiment, when winning in the advantageous state shift lottery process, the first set game number and the initial set continuation rate are then drawn. Here, the set continuation rate indicates the probability of starting the next set continuously after the end of the set.
Specifically, as shown in FIG. 15, the number of initial set games is uniformly 30 games.
On the other hand, the initial set continuation rate is set to 50% at a distribution rate of 35%, 60% at an allocation rate of 40%, 70% at an allocation rate of 20%, and 80% at an allocation rate of 5%.
Therefore, the expected value of the initial set continuation rate is set to 59.5%.
<2. Advantageous state>
FIG. 16 shows the flow of game processing during the advantageous state in the slot machine 1 of the second embodiment.
First, in step S1601, the advantageous state lamp YL is turned on, the advantageous game number is set to zero, and the number of set games is set to the initial set game number determined in the advantageous state transition lottery process.

In the next step S1602, an internal lottery process is executed. In response to this, in the next step S1603, 1 is added to the number of advantageous games and 1 is subtracted from the number of set games.
In the next step S1604, it is determined whether or not RT3 (inside the bonus), and if it is determined to be no, in the next step S1605, a lottery process is executed to add the continuation rate, while if it is determined to be yes. Skips step S1605 and proceeds to step S1606.

FIG. 17 shows the contents of the lottery process for adding the continuation rate.
In the continuation rate addition lottery process, the continuation rate to be added is set according to the internal lottery process result and the number of advantageous games at the current time.
Specifically, the continuation rate addition lottery process is executed when the lottery group GRP1, GRP14, or GRP18-20 is won as a result of the internal lottery process. The expected value of the continuation rate to be added as the limiter reaching remaining game number G ′, which is a value obtained by subtracting the current advantageous game number from the 1500 games which is the upper limit value of the advantageous game number to be forcibly ended, is calculated. It is decreasing.

FIG. 17 (a) shows the content of the continuation rate extra lottery when winning the lottery group GRP1 or GRP14, and FIG. 17 (b) shows the content of the continuation rate extra lottery when winning the lottery group GRP18-20. Yes.
As shown in FIG. 17 (a), when winning the lottery group GRP1 or GRP14, the continuation rate is increased by 20% at a distribution rate of 25% regardless of the limiter remaining game number G ′. The continuation rate is increased by 10% at the allocation rate, and the continuation rate is increased by 5% at the allocation rate of 50%.

On the other hand, when the lottery groups GRP18 to 20 are won, as shown in FIG. 17B, when the limiter-remaining remaining game number G ′ is small, the expected continuation rate to be added is larger than when it is large. It is decreasing.
Specifically, when the limiter reaching remaining game number G ′ is 500 or more, the continuation rate is increased by 20% at a distribution rate of 20%, and the continuation rate is increased by 10% at a distribution rate of 20%. The continuation rate will be increased by 5% at a distribution rate of%. Therefore, when the lottery group GRP18 to 20 is won and the limiter reaching remaining game number G ′ is 500 or more, the expected continuation rate to be added is 9%.

  On the other hand, when the limiter reaching remaining game number G ′ is less than 500, the continuation rate is increased by 20% at the allocation rate of 10%, and the continuation rate is increased by 10% at the allocation rate of 10%. The continuation rate will be increased by 5% at a distribution rate of%. Therefore, when the lottery groups GRP18 to 20 are won and the limiter reaching remaining game number G ′ is less than 500, the expected continuation rate to be added is 5%.

  Returning to FIG. 16, in the next step S1606, it is determined whether or not the lottery groups GRP2 to 13 are won. If it is determined that the answer is YES, it is determined whether or not the user is staying at RT0 in step S1607. When it is determined NO in step S1607, the correct answer push order is notified in the next step S1608, and the process proceeds to step S1609. On the other hand, when it is determined YES, that is, when staying at RT0, In order to shift to RT1, step S1608 is skipped and the process shifts to step S1609. Also when it is determined NO in step S1606, the process proceeds to step S1609.

In step S1609, it is determined whether or not the lottery groups GRP15 to 17 have been won. If the determination is yes, it is determined in step S1610 whether or not the user is staying at RT1. If it is determined as YES in step S1610, in the next step S1611, the correct answer push order is notified to shift to RT2, and the process shifts to step S1612.
When it is determined NO in step S1609 and when it is determined NO in step S1610, the process proceeds to step S1612.

  In step S1612, it is determined whether or not the lottery group GRP18 to 20 has been won. If it is determined that the lottery group GRP18 to 20 has been selected, it is determined in step S1613 whether or not the lottery process for winning the continuation rate executed in step S1605 has been won. to decide. If YES in step S1613, the correct answer pressing order is notified in step S1614. If NO is determined, a pressing order other than the correct pressing order is notified in step S1615, and step S1616 is notified. Transition.

In step S1616, it is determined whether or not the number of advantageous games has reached a limit value of 1500. If NO, it is determined in next step S1617 whether or not the number of set games has reached zero. If NO is determined in step S1617, the process returns to step S1602 to continue the advantageous state.
On the other hand, if it is determined YES in step S1617, a set continuous lottery process is executed in step S1618. In the set continuation lottery process, whether or not to start the next set is selected in accordance with the current continuation rate.
In the next step S1619, it is determined whether or not a winning is made in the set continuation lottery process. If it is determined to be yes, the next set game number and continuation rate are determined in step S1621 to start the next set. Execute the process.

FIG. 18 shows the contents of the next set game number and continuation rate determination processing.
In the next set game number and continuation rate determination process, the expected value of the next set game number and the expected value of the next set continuation rate are lowered as the limiter remaining game number G ′ decreases.

  Specifically, as shown in FIG. 18, when the limiter-remaining remaining game number G ′ is 500 or more, the next set game number is uniformly 30 games, and the next set continuation rate is the same as in the first set shown in FIG. For 50%, the allocation rate of 35% is 50%, the allocation rate of 40% is 60%, the allocation rate of 20% is 70%, and the allocation rate of 5% is 80%. Therefore, the expected value of the next set number of games is 30 games, and the expected value of the next set continuation rate is 59.5%.

  On the other hand, if the limiter reaching remaining game number G ′ is less than 500, the next set game is 20 games with the allocation rate of 25%, the next set continuation rate is 50%, and the allocation rate is 25%. 20 games, 60% for the next set continuation rate, 30 games for the next set game with 25% allocation rate, 50% for the next set continuation rate, 30 games for the next set game rate with 25% allocation rate The next set continuation rate is 60%. Therefore, the expected value of the next set number of games is 25 games, and the expected value of the next set continuation rate is 55%.

Returning to FIG. 16, if it is determined YES in step S1616 and NO in step S1619, an advantageous state end process is executed in step S1620 to end the advantageous state, and the next step In S1622, the process is shifted to the normal state process and the process is terminated.
Specifically, in the advantageous state end process, an advantageous state lamp YL is turned off, and an area on the RAM 43 in which various variables relating to the control during the advantageous state are stored is performed.

  As described above, also in the set continuation type slot machine 1 of the second embodiment, the limiter reaching remaining game number G ′ is 500 in the continuation rate addition lottery process when the lottery group GRP18-20 is won during the set digestion. In the above case, the expected continuation rate to be added is set to 9%. On the other hand, when the limiter reaching remaining game number G ′ is less than 500, the expected continuation rate to be added is set to 5% and the limiter reaching remaining amount is set. As the number of games G ′ decreases, a specification that reduces the expected value of the continued continuation rate is adopted.

  In addition to this, in the next set game number and continuation rate determination process when continuing to the next set, if the limiter arrival remaining game number G ′ is 500 or more, the expected value of the next set game number is 30 games, While the expected value of the next set continuation rate is 59.5%, if the limiter arrival remaining game number G ′ is less than 500, the expected value of the next set game number is 25 games, and the expected value of the next set continuation rate is 55%, and a specification is adopted that reduces the expected value of the next set game number and the expected value of the next set continuation rate as the limiter reaching remaining game number G ′ decreases.

  By adopting this specification, if the limiter-remaining remaining game number G ′ is less than 500, it will be difficult to continue compared to the case where it is 500 or more. As a result, the advantageous state is continued until the limiter function is activated. Basically, the advantage state is terminated by losing the set continuation lottery before reaching the limiter (determined as NO in step S1619 in FIG. 16) unless the luck is so good. I can do it. Therefore,

  Further, in the slot machine 1 of the second embodiment, as shown in FIG. 17B, in the advantageous state, in the game won in the lottery group GRP18-20, the limiter reaching remaining game number G ′ is less than 500. , 40% of the distribution rate, the continuation rate is not added.

Here, the lottery groups 18 to 20 are lottery groups in which the types of replay roles to be won are different depending on the operation order of the stop buttons 20L, 20C, and 20R, that is, the outcomes when all reels 4L, 4C, and 4R are stopped are different. is there.
As described above, in the slot machine 1 of the second embodiment, when the lottery groups 18 to 20 are added and adopted as the lottery trigger, and the continuation rate is added as a result of the lottery, the replaying role 6 (watermelon) RP) is notified of the correct pressing order in which the winning is to be performed, and if the continuation rate is not added, the re-game player 1 (normal RP) will be notified of the operating order other than the correct pressing order. I am going to do that.

  As a result, when the re-gamer 6 (watermelon RP) wins the player, the continuation rate is always added, while when the re-gamer 1 (normal RP) wins, the continuation rate Since it is possible to recognize that the addition of is not executed, a specification that reduces the expected value of the addition of the continuation rate according to the limiter arrival remaining game number G ′ is adopted, but such a specification is adopted. There is no risk that the player will notice.

Although one embodiment of the present invention has been described above, the present invention can be modified in various ways within the scope of matters described in the claims.
For example, in the first embodiment, the limiter function is activated when the number of executed games in the advantageous state reaches 1500 games. Instead, for example, the number of medals acquired in the advantageous state is 3000. The time when the sheet is reached may be adopted.

  In this case, for example, the approximate number of games until the limiter function is activated can be obtained by dividing the number of medals that can be acquired until the limiter function is activated by the expected medal payout number per game during the advantageous period. Therefore, the number G of games that can be added can be obtained by subtracting the current number of remaining games from the approximate number of games.

In other words, the value obtained by subtracting the current value of the counter used for determining whether or not to operate the limiter function from the upper limit value (1500 games / 3000 sheets) that activates the limiter function is advantageous due to the operation of the limiter function. On the other hand, the remaining number of games indicates the time when the player uses up the currently acquired execution right and the advantageous state ends.
The number G of games that can be added shows the difference between the estimated end times of the two, and when this is small, the winning probability of the additional number of remaining games and the remaining game number at the time of winning the lottery, compared to the case when it is large By reducing the expected number of added games, it is possible to avoid the limiter function from operating in a state where a large number of remaining games are held.
