Description

The present invention relates to a slot machine.

At present, AT machines, which are mainstream slot machines, basically reside in a bonus inside state in which a player has won a bonus combination but has not yet won a prize. For this reason, the specifications of the internal lottery process for lottery of winning combinations are always constant. The wave of balls to be played instructs the stop operation order (hereinafter referred to as "correct operation order") necessary for winning a correct answer small role with a large payout in a game in which a so-called push order small role is won as a result of the internal lottery process. It is created depending on whether or not the instruction function is activated, and the period during which a ball is obtained by operating the instruction function is called the AT (Assist Time) state.

The gambling performance of an AT machine is established by the balance between the ball dispensing performance in the AT state and the suction performance in the normal state, and in order to improve the ball dispensing performance, it is also necessary to improve the suction performance.
In AT machines, as a method to improve the suction performance under normal conditions, in order to force the player to play in a specific order of stop operations (for example, pressing left → middle → right), it is necessary to press other than the specific order of stop operations. A penalty specification that imposes a penalty when a game is played is known (for example, see Patent Document 1).
In the internal lottery process of the AT machine with penalty specifications, the winning probability of a push order small win (hereinafter referred to as push order small win A) in which the correct operation order is set other than a specific stop operation order is determined by It is set higher than the winning probability of the push order minor winning combination (hereinafter referred to as push order minor winning combination B) set in a specific order of stop operations. During the normal state, the player will proceed with the game in the above-mentioned specific stop operation order so as not to be penalized, but in a game where the player wins the push order minor winning combination B, which has a relatively high probability of winning. If the game is played in the specific stopping operation order, a small correct winning combination with a large payout will not be won, and as a result, the number of balls in the normal state can be kept low.

Also, in AT machines, a bonus game starts when a bonus combination is won, but if you suppress the ball output performance during this bonus game, you can increase the ball output performance in the AT state, so the bonus game AT machines are also known that use specifications that reduce the number of medals. Hereinafter, this specification will be referred to as a decreasing specification (for example, see Patent Document 2).

JP 2017-000263 Publication JP 2015-120052 Publication

By the way, in the case of a 3-reel slot machine, there are 6 different stop operation orders, but the decreasing bonus specification described in Patent Document 2 has 6 different push orders in which each of the 6 stop operation orders is set as the correct operation order. This is the most effective method when there is no bias in the winning probability of small roles. However, in the AT machine with the penalty specification, as mentioned above, there is a bias in the winning probability of the six types of small winning combinations, so the decreasing bonus specification described in Patent Document 2 does not sufficiently improve the ball payout performance during the bonus game. There was a problem that could not be reduced.

Replay roles 1 to 4 are selected as lottery targets in the internal lottery only in the bonus non-internal medium RT0 and bonus internal medium RT1, which have a specified number of 3 cards, and are not selected as the lottery target in the internal lottery in the bonus game RT2.

FIG. 8 shows a plurality of types of lottery categories to be selected as lottery targets in the internal lottery process of the slot machine 1.

The bonus lottery section G1 is a lottery section in which the RB role, which is a bonus role, and the Replay roles 1 to 4 are won in duplicate. In the slot machine 1, in a game where a bonus role and a minor role, or a bonus role and a replay role are won at the same time, reel stop control is adopted in which the minor role or the replay role is given priority over the bonus role. In the game in which the bonus lottery category G1 is won, any of the replay roles 1 to 4 will be won, but the RB role will not be won.

Each of the push order bell lottery sections G2 to G7 is a lottery section that is generally called a push order small winning combination. More specifically, if multiple types of small winning combinations with different payouts are won repeatedly, and the stop operation order matches the predetermined correct operation order, the small winning combination with the largest payout will win regardless of the stop operation timing. However, if the stop operation order does not match the correct operation order, the lottery classification is set so that the small winning combination with the largest payout will not win.
In a game where you win in any of push order bell lottery categories G2 to G7, if the stop operation order matches the correct operation order, any of the bells 1 to 4 with a payout of 10 pieces will be awarded regardless of the stop operation timing. However, if it does not match the correct operation order, none of the Bell 1-4 roles will win, and depending on the timing of the stop operation, the payout will be one of the incorrect Bell 1-10 roles. Either someone will win or they won't win.

The push order bell lottery section G2 is a lottery section in which the bells 1 to 2 roles and the incorrect bells 1 to 6 roles are won in duplicate, and the correct operation order is set as left → middle → right.
The push order bell lottery section G3 is a lottery section in which Bell 3 to 4 roles and incorrect Bell 1 to 7 roles are won over and over again, and the correct operation order is set in the order of left → right → middle.
Push order bell lottery section G4 is a lottery section in which Bell 1 role, incorrect answer Bell 1 to 6 roles, and incorrect answer Bell 8 role are won multiple times, and the correct operation order is set in the order of middle → left → right. ing.
Push order bell lottery section G5 is a lottery section in which Bell 2 role, incorrect answer Bell 1 to 6 roles, and incorrect answer Bell 9 role are won repeatedly, and the correct operation order is set in the order of middle → right → left. ing.
Push order bell lottery section G6 is a lottery section in which the Bell 3 role, incorrect Bell 1 to 6 roles, and incorrect Bell 10 role are won repeatedly, and the correct operation order is set in the order of right → middle → left. ing.
The push order bell lottery section G7 is a lottery section in which the Bell 4 role and the incorrect Bell 1 to 9 roles are won over and over again, and the correct operation order is set in the order of right → left → middle.

The rare small prize lottery section G8 is a lottery section in which cherry prizes 1 to 5 are won repeatedly. In the game in which the player wins the rare small prize lottery category G8, depending on the timing of the stop operation, either one of the prizes of 1 to 5 cherries with a payout of 1 piece will be won, or the prize will be missed.
The rare small prize lottery division G9 is a lottery division in which the watermelon prize is won alone. In the game where the player wins the rare small prize lottery category G9, depending on the timing of the stop operation, the watermelon prize with a payout of 4 pieces will be won or the prize will be missed.

Replay lottery section G10 is a lottery section in which replay roles 1 to 4 are won repeatedly. In the game where the replay lottery category G10 is won, any of the replay roles 1 to 4 wins regardless of the order and timing of the stop operations.

All small role duplicate lottery division G11 is a lottery where all small roles, specifically Bell 1 to 4 roles, incorrect Bell 1 to 10 roles, Cherry 1 to 5 roles, and Watermelon role are won repeatedly. It is a classification. The all small role duplicate lottery section G11 is a lottery section exclusively for RB games, and in the game where you win the all small role duplicate lottery section G11 during the RB game, Bell 1 to 4 roles, no win, regardless of the stop operation order and timing. The correct answer will be either Bell 1 to 10, Cherry 1 to 5, or Watermelon. Further, as described above, the specified number in the RB game is 2, and when the specified number is 2, the payout for all small winning combinations is set to 1, so the payout for winning is 1.

Next, with reference to FIGS. 9 and 10, lottery specifications in each RT state at setting values 1 to 6 of the slot machine 1 will be explained.
Note that FIGS. 9 and 10 show lottery values corresponding to the winning range of each lottery category for each set value. Note that the range of random numbers in the internal lottery process is 0 to 65535, so the winning probability for each lottery category for each set value can be calculated as lottery value/65536.

FIG. 9 shows lottery specifications for bonus non-internal medium RT0 and bonus internal medium RT1.
The lottery value of the bonus lottery category G1 is set to 16384 regardless of the setting value, and the winning probability is set to 1/4. As mentioned above, if you win bonus non-internal medium RT0 and bonus lottery category G1, you will move to bonus internal medium RT1, but after moving to bonus internal medium RT1, the RB role will be excluded from the targets for internal lottery. In the bonus internal RT1, if you win the bonus lottery category G1, it will be a duplicate win for Replay 1 to 4 roles.

The lottery values for the push order bell lottery categories G2 and G3 are each set to 4000 regardless of the set value, and the winning probability is set to approximately 1/16.38.
The lottery values for the push order bell lottery categories G4 to G7 are each set to 8000 regardless of the set value, and the winning probability is set to approximately 1/8.19.
The lottery value for rare small role lottery category G8 is 1600 if the setting value is 1, 1660 if the setting value is 2, 1768 if the setting value is 3, 1884 if the setting value is 4, If the setting value is 5, it is set to 1960, and if the setting value is 6, it is set to 2048.
The lottery value of rare small role lottery category G9 is 546 if the setting value is 1, 565 if the setting value is 2, 585 if the setting value is 3, 607 if the setting value is 4, If the setting value is 5, it is set to 630, and if the setting value is 6, it is set to 655.
The lottery values for replay lottery category G10 are 7006 when the setting value is 1, 6927 when the setting value is 2, 6799 when the setting value is 3, 6661 when the setting value is 4, and 6661 when the setting value is 5. If the setting value is 6, it is set to 6562, and if the setting value is 6, it is set to 6449.
Furthermore, as a result of the internal lottery during Bonus Non-Internal Medium RT0 and Bonus Internal Medium RT1, there is no so-called loss where you do not win any of the lottery categories G1 to G10, and you will definitely win any of the lottery categories G1 to G10. It is configured as follows.

Furthermore, as mentioned above, in the slot machine 1, in a game where a bonus role and a minor role or a replay role are won at the same time, the reel stop control is used to give priority to the minor role or the replay role over the bonus role. , since the internal lottery result during the bonus internal RT1 will never be a loss, the winning opportunity for the RB role is the game won in the rare minor prize lottery category G8 or the rare minor prize lottery category G9 during the bonus internal intermediate RT1. This is limited to when you perform a stop operation aiming at the black bar symbol in a game where you win. Therefore, it is extremely rare for the RB role to win in the bonus internal medium RT1, and after winning the bonus lottery category G1 with a winning probability of 1/4 in the bonus non-internal medium RT0 and moving to the bonus internal medium RT1, the basic In other words, it will continue to stay at RT1 during the bonus period.

FIG. 10 shows the lottery specifications for the bonus game RT2.
In the internal lottery in the bonus game RT2, only the all minor role duplication lottery category G11 is selected as a lottery target, and the lottery value is set to 65536 regardless of the setting value, and the winning probability is set to 1/1. As mentioned above, in the bonus game RT2, that is, the game in which all small role duplicate lottery division G11 was won in the RB game, Bell 1 to 4 roles, incorrect Bell 1 to 10 roles, and Cherry, regardless of the stop operation order and timing. Either the 1st to 5th prize or the watermelon prize will win, but as mentioned above, the specified number in the RB game is 2, and if the specified number is 2, the payout for all small prizes is set to 1. Therefore, the payout for winning is one coin. Furthermore, as described above, the RB game ends when the number of medals paid out during the RB game exceeds eight. Therefore, in the RB game, a game in which one payout is obtained for each two medals inserted is repeated for nine games, and as a result, there are nine fewer medals at the end of the RB game than at the beginning of the RB game. It turns out. Therefore, the RB game has a bonus that reduces the number of medals, that is, the slot machine 1 adopts a so-called bonus bonus that reduces the number of medals.

Therefore, in the slot machine 1, in the RB game, nine games in which one medal is lost are repeated, and as a result, the player only loses nine medals, so there is no benefit for the player to win the RB combination. be. In addition, as mentioned above, the chance of winning the RB role is extremely rare, and when the winning opportunity arrives, unless you aim at the black bar symbol and perform the stop operation, the RB role will not win, so there is no chance of winning the RB role in the hole. is unlikely to win.

On the other hand, in the simulation test for the slot machine type certification test, the so-called bonus role, which once won, will remain won until it is won, is assumed to be won in the winning game (hereinafter referred to as premise 1), and the so-called bonus role is As for winnings, a simulation is performed assuming that the maximum payout minor winning game wins in all winning games regardless of whether the instruction function is activated (hereinafter referred to as premise 2), and as a result, medals exceeding the standard can be obtained. If this happens, the product will not comply with the type certification test. Slot machines that do not meet the type certification test cannot be installed in the hall.

The simulation test can be said to be a test based on the above premise 1 that there is no bonus inside, and based on the above premise 2, it is assumed that all stop operations are performed in the correct operation order when winning the so-called push order combination. As mentioned above, in slot machine 1, the probability of winning RT0 in bonus lottery category G1 including RB role is 1/4, so in the simulation test, the probability of winning RT0 in bonus lottery category G1 including RB role is 1/4. The number of games RT0 stays on is 4 on average, the RB role wins in the winning game, and after winning, the RB game is executed for 9 games with 9 medals reduced, and then returns to RT0 with no bonus inside, repeating the loop. It turns out.
Therefore, from the above premise 2, the medal increase period in the simulation test will be RT0 during the non-bonus internal period, but as mentioned above, it will end in an extremely short period of 4 games on average, and the net increase in medals per game will be about 4. .2 sheets (calculated from Figures 8 and 9), it is designed so that it will not fail the type test in the simulation test.

According to the rules related to gaming machines, a bonus game is a period in which the probability of winning a small prize can be varied, and is originally intended to be used as a gaming period that is more advantageous than normal times other than during bonus games. Therefore, the winning probabilities of all small winning combinations during the bonus game must be improved compared to the normal time. In slot machine 1, the winning probability of each small role in the RB game is 1/1, which is higher than the winning probability of each small role of bonus non-internal medium RT0 and bonus internal medium RT1. meets the requirements. In this way, the slot machine 1 achieves a reduction in winnings using an extremely simple method.

Also, without changing the specified number during the bonus, out of multiple small winnings that would normally be included in multiple lottery categories, small winnings with the same payout can be combined into one lottery category and won simultaneously, and can be combined. If you use the conventional method of achieving a reduced number of winnings by setting the empty numerical range in the internal lottery as a loss, the number of correct small winnings included in the multiple types of pressing order small winnings in normal times. It is also necessary that the winning probability of the correct answer small winning lottery category that combines the above into one is higher than the winning probability of the lottery category with the highest winning probability among the plurality of types of pressed order small winning combinations.
As shown in FIG. 9, this slot machine 1 adopts a penalty specification that biases the winning probability of the pressed order bells G2 to G7. The lottery value of the lottery category needs to be at least larger than 8000, which is the highest lottery value among the lottery values of the normal pressing order bells G2 to G7.

In addition, the penalty specification is a specification adopted to increase the net increase during the AT period. The higher the winning probability of a small winning combination (hereinafter referred to as a penalty subject push order small winning combination), the better, and the larger the payout of a correct small winning combination, the better.
Therefore, when applying the conventional decreasing bet method to a slot machine with a penalty specification, the winning probability of the correct small winning lottery category in the bonus will be lower due to the higher winning probability of the small winning winnings that are subject to penalties in normal times. As a result, the desired suction performance may not be obtained during the bonus.

On the other hand, in place of the conventional method of reducing bets, the new method of reducing bets adopted in slot machine 1 is extremely simple, regardless of the winning probability of the small winnings in the order of pressing that are subject to penalty in normal times or the payout of the correct winnings. In this way, it is possible to realize a bonus that decreases by one coin every game. At the design stage of a slot machine, if you can achieve a bonus that decreases by one or more coins every game by adopting the conventional decreasing bonus method, then you can use the conventional decreasing bonus method, but if it cannot be achieved, It is sufficient to use the new method of reducing bets adopted in the slot machine 1.

<5. Detailed explanation of the game＞
Next, details of the game on the slot machine 1 will be explained.

<5-1. Game state flow related to instruction function>
FIG. 11 is a diagram showing the game state transition related to the instruction function in the slot machine 1.

The gaming state related to the instruction function of the slot machine 1 is roughly divided into a non-advantageous state in which the instruction function cannot be activated, and an advantageous state in which the instruction function can be activated. When the instruction function is activated, in a game in which any of the push order bells G2 to G7 is won, a command is sent from the main control device 100a to the production sub-control device 100b to instruct the correct operation order, and the instruction monitor Identification information corresponding to the correct operation order is displayed on the NM. The production sub-control device 100b notifies the player of the correct operation order by displaying on the liquid crystal display 30 and outputting audio from the speakers 31, 31 in accordance with an instruction command from the main control device 100a. The fact that the main control device 100a displays identification information on the instruction monitor NM and sends an instruction command to the production sub-control device 100b is referred to as activation of the instruction function.
During the non-advantageous state, the advantageous section lamp YL is turned off, and an advantageous state shift lottery is executed according to the result of the internal lottery process, and if the advantageous state shift lottery is won, the advantageous state is shifted to the advantageous state.

The advantageous states include a first advantageous state in which the indicating function is not activated, and a second advantageous state in which the indicating function is activated. The second advantageous state is called the AT state. When winning the advantageous state shift lottery, the first advantageous state is first entered.
Then, in the first advantageous state, when the AT state transition lottery is won or the number of executed games reaches the ceiling number of games without winning the AT state transition lottery, the AT state is transitioned to. The advantageous section lamp YL is turned from the off state to the on state at the same time as the transition to the AT state.
When the AT state ends, the vehicle falls to a non-advantageous state, and at the same time, the advantageous section lamp YL is also turned off from the lit state.

Further, the slot machine 1 is equipped with a limiter function related to an advantageous state. Specifically, the limiter function is activated when the number of games executed during an advantageous state reaches 1500 games, or when the difference in the number of medals during an advantageous state (the difference between the number of medals acquired during an advantageous state and the number of medals inserted) becomes 2400. If the value exceeds the value, the advantageous state is forcibly terminated and the state is shifted to a non-advantageous state.
Therefore, the AT state ends either when the right to continue the AT state, specifically, when the remaining number of games or the remaining set stock number is exhausted, or when the limiter function is activated.

Hereinafter, game control related to the instruction function will be explained.
As described with reference to FIG. 6, the RT state of the slot machine 1 is any one of RT0 to RT3, and among these, RT0 during bonus non-internal is the RT state after the setting change. At the time of setting change, the gaming state related to the instruction function is also set to a non-advantageous state. Further, in RT0 during bonus non-internal, the above-mentioned advantageous state transition lottery is not performed.
Therefore, while staying at RT0 while the bonus is not internal, the state does not shift to an advantageous state, and while the bonus is not internal and staying at RT0, it is set to a non-advantageous state.

Then, on the condition that the bonus lottery category G1 is won in bonus non-internal RT0 and the transition is made to bonus internal RT1, various lottery processes related to the instruction function, including the above-mentioned advantageous state transition lottery, are executed. It is said that

<5-2. Unfavorable situation>
FIG. 12 is a flowchart showing the processing flow of the slot machine 1 during a non-advantageous state.
During the non-advantageous state, first, an internal lottery process is executed in step S1201, and in step S1202, it is stopped in the order of left → middle → right or left → right → middle (hereinafter collectively referred to as "left 1st"). Determine whether an operation has been performed. If it is determined to be YES in step S1202, an advantageous state transition lottery process is executed in step S1203. In the next step S1204, it is determined whether or not the winning state has been won in the advantageous state transition lottery process in step S1203. If the determination is YES, in step S1205, after executing the advantageous state start process, the first advantageous state is changed. To start, the first advantageous state processing is started in step S1206, and the process returns.
Specifically, the advantageous state transition lottery process in step S1203 is executed in a game where any of the lottery categories G1 to G7 is won as a result of the internal lottery process, and the probability of winning is set to 50%. Further, in the advantageous state starting process of step S1205, various initialization processes necessary at the start of the advantageous state are executed, such as initialization processing of various counters such as the number of games executed during the advantageous state and the number of difference sheets.

On the other hand, if it is determined NO in step S1202, that is, if the stop operation is performed in an order other than the left 1st, the advantageous state shift lottery process in step S1203 is not performed as a penalty. Therefore, in this case, the process returns to step S1201 and the non-advantageous state continues.

<5-3. First advantageous state>
FIG. 13 is a flowchart showing the processing flow of the slot machine 1 during the first advantageous state.
During the first advantageous state, first, in step S1301, an internal lottery process is executed, and in step S1302, it is determined whether a stop operation has been performed in the left 1st position. If the answer is yes in step S1302, AT state transition lottery processing is executed in step S1303. On the other hand, if it is determined NO in step S1302, that is, if the stop operation is performed in an order other than left 1st, the AT state transition lottery process in step S1303 is skipped as a penalty, and the process proceeds to step S1304. A detailed explanation of the AT transition lottery process will be omitted.
In step S1304, the number of played games is incremented by 1, and in the next step S1305, it is determined whether the number of played games has reached the ceiling number of games. Note that the number of games played is set to zero as an initial value in the above-mentioned advantageous state start process (S1205).
If the determination in step S1305 is NO, it is determined in step S1306 whether or not the AT state transition lottery process in step S1303 was won. If the determination is YES, the process moves to step S1307. If the determination in step S1305 is YES, the process also moves to step S1307. In step S1307, in order to start the AT state, processing during the AT state is started, and the process returns.
On the other hand, if the determination in step S1306 is NO, the process returns to step S1301 and the first advantageous state continues.

<5-4. AT state (second advantageous state)>
FIG. 14 is a flowchart showing the flow of processing during the AT state (second advantageous state) of the slot machine 1.
During the AT state, first, an internal lottery process is executed in step S1401, and in step S1402, it is determined whether any of the push order bells G2 to G7 has been won. If it is determined YES in step S1402, that is, in a game in which any of the push order bells G2 to G7 is won, steps S1403 to S1406 are performed, which will be described later. On the other hand, if the determination in step S1402 is NO, the process moves to step S1407.
In step S1407, according to the internal lottery result, an additional lottery process is executed for a parameter (hereinafter referred to as AT continuation right) that is consumed as consideration for continuing the AT state and ends AT when it is exhausted. will add AT continuation rights. In the next step S1408, when the instruction mode is the low net increase mode, a mode up lottery process is executed to determine whether to promote to the high net increase mode. The instruction mode will be described later. In the next step S1409, it is determined whether or not to continue the AT state by checking whether the AT continuation right is present and whether the limiter activation conditions are met. If the determination is yes, the process returns to step S1401. While the AT state is continued, if the answer is NO, the process executes the advantageous state end process in step S1410, starts the non-advantageous state process in step S1411, and returns. Specifically, in the advantageous state termination process, all information related to the instruction function used to control the advantageous condition to be terminated is cleared.

<5-4-1. Processing when winning push order bells G2 to G7>
Next, the processing of steps S1403 to S1406 will be explained.
The instruction mode of slot machine 1 refers to the operation mode of the instruction function when the push order bell G2 to G7 is won during the AT state. It has a low net increase mode in which the instruction function is not operated at a certain rate, and the instruction mode at the start of the AT state is the low net increase mode, and after winning in the mode up lottery process in step S1408 described above, it is the high net increase mode. be done.

In step S1403, it is determined whether the instruction mode is low net increase mode or not. If the determination is no, that is, if it is high net increase mode, steps S1404 to 1405 are skipped and the process moves to step S1406. On the other hand, if the determination in step S1403 is YES, that is, in the case of low net increase mode, an instruction execution lottery process is executed in step S1404. In the next step S1405, it is determined whether or not a winner has been won in the instruction execution lottery process. If the determination is yes, the process moves to step S1406, while if the determination is no, the process skips step S1406. The process moves to step S1407. In step S1406, the instruction function is activated to notify the correct operation order, and the process moves to step S1407.

<5-4-2. Instruction execution lottery process>
FIG. 15 shows the contents of the instruction execution lottery process.
As mentioned above, since the slot machine 1 adopts a penalty specification, the probability of winning for the push order bells G2 and G3 whose correct operation order is set to the left 1st is 4000/65536, but when the correct operation order is set to the left 1st, the winning probability is 4000/65536. The probability of winning for the push order bells G4 to G7 set to is as high as 8000/65536.
For this reason, for example, if an instruction execution lottery is conducted with a uniform probability regardless of whether any of the push order bells G2 to G7 is won, even in a game in which it is decided not to instruct (hereinafter referred to as a game without instructions), the push order bell The probability of winning in G4 to G7 is higher than the probability of winning in push order bells G2 and G3. That is, in the no-instruction game, if the stop operation is performed in an order other than the left 1st, the probability of matching the correct operation order is higher than if the stop operation is performed in the left 1st order. Therefore, in a game without instructions during the AT state, there is a problem that unfairness occurs between a player who performs a stop operation in an order other than the left 1st and a player who performs a stop operation in an order other than the left 1st.

Therefore, in slot machine 1, in order to solve this problem, in a game without instructions, no matter in which order the stop operation is performed, the probability of matching the correct operation order is the same. Considering the probability of winning for each G7, the probability of winning the instruction execution lottery was determined for each of the bells G2 to G7 in the order of pressing.
Specifically, as shown in FIG. 15, the probability of winning the instruction execution lottery in the game where the push order bells G2 and G3 are won is 50%, and the probability of winning the instruction execution lottery in the game where the push order bells G4 to G7 are won is 50%. Each was set at 75%.

As a result, the no-instruction probability of a no-instruction game can be set to 2000/65536, which is the same for games in which any of the push order bells G2 to G7 is won, so the stop operation can be performed in any order in the no-instruction game. Even if this is done, the probability of matching the correct operation order can be made the same. As a result, the expected payout value in the no-instruction game can be made equal for all stop operation orders.
Further, as described in the last line of FIG. 15, in the low net increase mode, the instruction execution lottery winning probability for the entire push order bell G2 to G7 winning game is set to 70%.

As explained above, according to the instruction execution lottery method of the slot machine 1, in an AT machine with a penalty specification that changes the ball output performance in stages during the AT state, in the above-mentioned game without instructions, the player Even if the stop operations are performed in the order of operations, no unfairness will occur depending on the order of the stop operations, and the ball dispensing performance as designed can be achieved.

Although the embodiments of the present invention have been described above, various design changes can be made to the present invention within the scope of the claims.
