As described above, the replay combination is a combination that allows the execution of the next one game without a bet of medals, although there is no payout for winning, and the winning probability is set to 1 / 6.4.

The push order small combinations 1 to 6 are different from each other in the combination of a single small combination and a winning combination of six small combinations and a plurality of types of small combinations that are permitted to receive a prize.
Push order small combinations 1 to 6 are allowed to receive a prize so that the operation order of the stop buttons 20L, 20C, and 20R (hereinafter referred to as correct answer push order) required for winning a small combination with six payouts is different from each other. A combination of a plurality of small combinations is determined in advance, and when the stop buttons 20L, 20C, and 20R are operated in the correct pressing order when the winning combinations 1 to 6 are selected, the payout is 6 small combinations. Wins, and if the stop buttons 20L, 20C, 20R are operated in the order other than the correct pressing order, a small combination with one payout is won.

Specifically, the correct pressing order for push order small 1 is left → middle → right, the correct pressing order for push order small 2 is left → right → middle, and the correct pressing order for push order small 3 is middle → left → Right, the correct order of push order 4 is middle → right → left, the correct order of push order 5 is right → left → middle, and the correct order of push order 6 is right → middle → left. Each is set.
The winning probabilities for the push orders 1-6 are set to 1 / 9.6.

Dividends for small roles 1 and 2 are 3 each, and the winning probability is set to 1/15. The payouts for rare small roles 1 to 4 are set to 1 each. The winning probability is set to 1/44, the winning probability of Rare Small Role 2 is set to 1/126, the winning probability of Rare Small Role 3 is set to 1/300, and the winning probability of Rare Small Role 4 is set to 1/3640.
From the above, the probability of losing none of the replay combination, push order small combination 1-6, small combination 1-2, rare small combination 1-4 is 1 / 19.6.

<3. Normal state>
FIG. 5 shows the flow of the game process in the normal state.
First, an internal lottery process is executed in step S501, and an advantageous state transition lottery process (low probability) is executed in the next step S502 according to the result of the internal lottery process.
FIG. 6A shows the specific lottery contents of the advantageous state transition lottery process (low probability).
As a result of the internal lottery process in the normal state, the advantageous state transition lottery process (low probability) is not executed and skipped in the game where the replay combination and the push order small combinations 1 to 6 are won.

  In the game in which the small roles 1 and 2 are won during the normal state, it is determined only whether or not to shift to the high probability state. The probability of determining to shift to the high-accuracy state is set to 2% for a game won for small role 1 and 3% for a game won for small role 1.

In the game in which the rare small roles 1 to 4 are won during the normal state, it is determined whether or not to shift to the AT state and whether or not to shift to the high probability state.
First, it is determined whether or not to shift to the AT state. The probability of determining to shift to the AT state is 1% for a game won by Rare Minor 1, 10% for a game won by Rare Minor 2, 50% for a game won by Rare Minor 3, In the game won 4th, it is set to 100%.

  If it is not determined to shift to the AT state, it is next determined whether or not to shift to the high-accuracy state. The probability of determining to move to the high accuracy state is set to 20% for a game won for Rare Small Role 1, 50% for a game won for Rare Small Role 2, and 1000% for a game won for Rare Small Role 3. ing.

Returning to FIG. 5, in the next step S503, it is determined whether or not the winning state is determined as a result of the advantageous state transition lottery process (low probability). Specifically, if it is determined to shift to the AT state or the high probability state as a result of the advantageous state transition lottery process (low accuracy), it is determined that the winning is made.
If it is determined as YES in step S503, the process proceeds to the advantageous state process in step S504 to end the normal state process. On the other hand, if it is determined NO, the process returns to step S501.

<4. Advantageous state>
The advantageous state of the slot machine 1 includes two game states, an AT state and a highly probable state.
The AT state is a game state in which information related to the correct pressing order is notified in a game in which one of the pressing order small combinations 1 to 6 is won. On the other hand, the high-accuracy state is a game in which one of the push order small roles 1 to 6 is won, and information related to the correct push order is not notified, but the game state has a higher probability of transition to the AT state than the normal state. .

FIG. 7 shows the flow of the game process during the advantageous state.
First, in step S701, the advantageous state lamp YL is turned on and the number of advantageous games is set to zero. In the next step S702, it is determined whether or not it is determined to shift to the AT state as a result of the above-described advantageous state transition lottery process (low probability). If YES is determined in step S702, the process proceeds to an AT process in step S703. If NO is determined, the process proceeds to a highly accurate process in step S704, and the process returns.

<4-1. Processing during AT>
FIG. 8 shows the flow of game processing during AT.
First, in step S801, 1 is set for each of the number of sets and the specialized zone flag. In the next step S802, zero is set for each of the set game number and the point number.

  Here, the number of sets indicates 30 games per set, and indicates the remaining number of the set. The number of set games indicates the number of games consumed during the current set, and the number of points indicates the number of points acquired during the current set. The specialized zone flag will be described later.

In the next step S803, an internal lottery process is executed. In response to this, in the next step S804, 1 is added to the set game number and the advantageous game number.
In the next step S805, it is determined whether or not the number of advantageous games has reached 1500 games. If it is determined to be yes, the process proceeds to step S821, whereas if it is determined to be no, the process proceeds to step S806.

  In step S806, it is determined whether or not the specialized zone flag is 1. If it is determined that the answer is yes, a highly accurate point giving lottery process is executed in step S807, while if it is determined that the answer is no, the value is decreased in step S808. The certain point giving lottery process is executed, and the process proceeds to the next step S809. In step S809, it is determined whether or not the number of set games has reached 5. If YES, the special zone flag is set to zero in step S810 and the process proceeds to step S811, while no is determined. If so, the process skips step S810 and proceeds to step S811.

  As described above, the special zone flag is a flag for determining whether or not to execute the high-precision point giving lottery process in step S807. If 1 is set in the special zone flag, A highly accurate point giving lottery process is executed over 5 games from the start of the set.

FIG. 10A shows the content of the low-accuracy point giving lottery process, and FIG. 10B shows the content of the high-accuracy point giving lottery process.
As shown in FIGS. 10 (a) and 10 (b), in the low / high accuracy point giving lottery process, whether or not points are given according to the internal winning combination, and if so, the number of points is drawn. To do.

Specifically, in the low probability point giving lottery process, as shown in FIG. 10A, an average of 5 points is awarded with a probability of 50% in the game won in the replay role.
In a game where one of the push order small combinations 1 to 6 is won, the low probability point giving lottery is not executed and no points are given.
In the game where the small role 1 or the small role 2 is won, an average of 10 points is awarded with a probability of 50%.
In a game won by Rare Small Bonus 1, an average of 30 points is awarded.
In a game won by Rare Small Role 2, an average of 40 points is awarded.
In a game won by Rare Small Role 3, an average of 60 points is awarded.
In the game won for Rare Small Role 4, an average of 80 points is awarded.
In the lost game, an average of 5 points is awarded with a probability of 50%.
In consideration of the internal winning probability for each combination shown in FIG. 4, the expected point grant value per game in the low probability point giving lottery process is set to about 2.41 points.

In the high-accuracy point giving lottery process, as shown in FIG. 10 (b), an average of 5 points is awarded in the game won in the replay role.
An average of 1 point is awarded in a game in which one of the push order small combinations 1 to 6 is won.
In the game where the small role 1 or the small role 2 is won, an average of 10 points is awarded.
In a game won by Rare Small Bonus 1, an average of 30 points is awarded.
In a game won by Rare Small Role 2, an average of 40 points is awarded.
In a game won by Rare Small Role 3, an average of 60 points is awarded.
In the game won for Rare Small Role 4, an average of 80 points is awarded.
An average of 5 points will be awarded for lost games.
In consideration of the internal winning probability for each combination shown in FIG. 4, the expected point grant value per game in the highly accurate point giving lottery process is set to about 4.22 points.
As described above, in the high-accuracy point lottery process, the expected point grant value per game is larger than in the low-accuracy point award lottery process.

  Returning to FIG. 8, in the first step of the AT process, step S801, as can be seen from the fact that the specialized zone flag is set to 1, the normal state or the high-accuracy state has shifted to the AT state. Since the special zone flag is set to 1 at the time of the first set, the expected point acquisition value at the beginning of the first set is relatively high.

Returning to step S811 in FIG. 8, in this step, it is determined whether the number of points is 100 points or more. If the determination is yes, in step S812, the number of sets is added and a lottery process is performed, and the process proceeds to step S813. If NO is determined, step S812 is skipped and the process proceeds to step S813.
As will be described later, the slot machine 1 adopts a specification in which the continuation of the next set is fixed when the number of points acquired during the set becomes 100 points or more. In addition to this, in the game in which the number of points acquired during the set is 100 points or more, a specification is adopted in which the lottery process is executed by adding the number of sets in step S812.

FIG. 11 shows the contents of the lottery process with the number of sets added.
As shown in FIG. 11, in the set number extra lottery process, whether or not to add the number of sets is added according to the internal winning combination, and when it is added, the number of sets is drawn.
Specifically, the lottery process is not executed by adding the number of sets in a game that has been selected as one of the replay role, push order small roles 1 to 6, small role 1 or small role 2, or lost game. The number of sets is not added.
In a game won by Rare Small Role 1, an average of one set is added with a probability of 20%.
In the game that won Rare Small Role 2, an average of 2 sets are added with a probability of 30%.
In a game where Rare Small Role 3 is won, an average of 3 sets will be added with a 50% probability.
In the game won for Rare Small Role 4, an average of 5 sets will be added.

Returning to step S813 in FIG. 8, in this step, it is determined whether or not the number of set games has reached 30 games. If it is determined to be no, the process returns to step S803 and the setting is continued.
On the other hand, if it is determined as YES in step S813, that is, if it is determined that the set end game, 1 is subtracted from the number of sets in step S814.

  In the next step S815, it is determined whether or not the number of points is less than 100 points. If it is determined as YES, the next set continuous lottery process is executed in step S816. In the next set continuous lottery process, a lottery with the number of points as the continuation probability (%) is performed. For example, if the number of points is 70 points, a continuous lottery with a continuation probability of 70% is performed, and if it is 80 points, a continuous lottery with a continuation probability of 80% is performed.

  In the next step S818, it is determined whether or not the next set continuous lottery process in step S816 has been won. If it is determined to be yes, 1 is added to the number of sets in step S819 and the process proceeds to step S820. If NO is determined, step S819 is skipped and the process proceeds to step S820.

  On the other hand, if it is determined NO in step S815, specifically, if the number of points acquired in the set end game is 100 points or more, the special zone flag is set to 1 in step S817, As described above, since the continuation of the next set is confirmed, 1 is added to the number of sets in the next step S819, and the process proceeds to step S820.

  When the number of points earned in the set end game is 100 points or more, as shown in the fact that the special zone flag is set to 1 in step S817, the next set early is the same as the initial set early In addition, the expected point acquisition value is relatively high.

In step S820, it is determined whether or not the number of sets is zero, and if it is determined to be no, that is, if a transition to the next set is made, the process returns to step S802.
On the other hand, when it is determined YES in step S820, that is, when the AT state is ended in the set, and when YES is determined in step S805, that is, the number of games digested in the advantageous state reaches 1500 games and the limiter function is reached. If is activated, an advantageous state termination process is executed in the next step S821. 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 cleared.
Then, in the next step, the process is shifted to the normal state process, and the AT process is terminated.

<4-2. High accuracy middle processing>
FIG. 9 shows the flow of the game process with high probability.
First, in step S901, an internal lottery process is executed, and in accordance with this, 1 is added to the number of advantageous games in the next step S902.
In the next step S903, an advantageous state transition lottery process (high accuracy) is executed.
Specifically, in the advantageous state transition lottery process (high accuracy), as shown in FIG. 6B, it is determined whether or not to shift to the AT state in the game won by the rare small roles 1 to 4. The advantage state lottery process (high accuracy) is not executed in the game where the replay combination, the push order small combinations 1 to 6, the small combination 1 or the small combination 2 are won, and the game is lost.
The probability of determining to shift to the AT state is 5% for a game won for Rare Small Role 1, 20% for a game won for Rare Small Role 2, and 100 for a game won for Rare Small Role 3 or Rare Small Role 4. % Is set. In the advantageous state transition lottery process (high probability), the AT transition probability when the rare small roles 1 to 4 are won is higher than in the advantageous state transition lottery process (low probability) shown in FIG.

Returning to FIG. 9, in the next step S904, it is determined whether or not the advantageous state transition lottery process (high accuracy) of step S903 has been won. The process ends.
On the other hand, if it is determined NO in step S903, the falling lottery process is executed in the next step S905. Specifically, as shown in FIG. 6B, the falling lottery process is executed only in the game that has won the replay role, and the winning order 1-6, small 1-2, and rare 1-4 are selected. It is not executed in the game that has been lost or lost.
The winning probability of the falling lottery process in the game won for the replay role is set to 20%.

Returning to FIG. 9, in the next step S906, it is determined whether or not the falling lottery process in step S905 has been won. If it is determined no, the process returns to step S901 and the high-probability process is continued.
On the other hand, if it is determined as YES in step S906, that is, if the winning lottery process is won, after executing the advantageous state end process in step S907, the process proceeds to the normal state process in the next step S908. Then, the high-probability middle processing is terminated.

As described above, in the slot machine 1, the continuation of the next set is confirmed if the number of points acquired in one set is 100 points or more, and even if it is less than 100 points, the number of points acquired is large. The specifications that increase the expected value for the next set will be adopted.
In addition, according to the slot machine 1, in the early stage of the first set that transitioned from the normal state or the high-accuracy state to the AT state, and in the early stage of the next set in which the continuation was confirmed by acquiring 100 points or more during the previous set, Compared to the early stage of the next set, which has acquired less than 100 points and won the next set continuation lottery, the point acquisition expected value becomes higher.

  At the beginning of the first set, the player is immersed in the afterglow of accomplishment of achieving the AT transition, but on the future development that "AT should continue for a long time in this condition ..." A psychological state with a sense of anxiety. At the beginning of the first set under this psychological state, by raising the expected value of point acquisition, the sense of anxiety can be resolved, and a sense of security "Let's do this!" Can be given.

  Also, if 100 points or more are scored during the previous set and the set continuation is confirmed, the player is immersed in the aftermath of a sense of accomplishment that the transition to the next set has been confirmed. It is in a psychological state with a sense of anxiety about future development. In the early stage of the next set under this psychological state, by raising the expected value of point acquisition, the sense of anxiety can be resolved, and a sense of security “Let's do this!” Can be given.

  In this way, increasing the point expectation value at the beginning of the set start in a psychological state with a sense of anxiety about future development while being immersed in the reverberation of achievement is very effective as a means to resolve anxiety It is. As a result, the player can be immersed in the game.

In addition, each part structure of this invention is not restricted to the said embodiment, A various deformation | transformation is possible within the technical scope as described in a claim.
For example, in the above embodiment, the period when the expected point acquisition value is high (high accuracy point giving lottery process) is executed in the next set when 100 points or more are acquired during the first set and the previous set and the set continuation is confirmed. Although five games have been set since the start of the set, the number of games since the start of the set can be changed within a common sense meaning the beginning.
As there are the words “early”, “mid” and “late”, the term “early” is understood to be a period within about 1/3 from the start of one set period.

In addition, for example, instead of the above-described period when the expected point acquisition value is high, the number of points at the start of the set in the next set when 100 points or more are acquired during the first set and the previous set and the set continuation is confirmed. The initial value may be set higher.
Furthermore, when 100 points or more are acquired during the previous set and the set continuation is confirmed, the surplus points exceeding 100 points may be carried over to the next set.

  Furthermore, in the above-described embodiment, if the player wins less than 100 points during the previous set, wins the next set continuation lottery, and shifts to the next set, the low-accuracy point grant lottery is also performed in the early stage of the next set. Even if the next set continuation lottery is won, if the continuation of the set is confirmed by acquiring 100 points or more during the first set and the previous set, the points at the beginning of the next set start will be obtained As long as the expected value is not exceeded, the point acquisition expected value at the beginning of the next set may be increased.

  In this case, when the next set continuation lottery is won, it may be determined whether or not the point acquisition expected value at the beginning of the next set is increased with a winning probability of less than 100%.

  The present invention can be applied to a slot machine.
