Description

The present invention relates to slot machines.

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

The gambling performance of an AT machine is established by the balance between the ball delivery performance in the AT state and the suction performance in the normal state.
In the AT machine, as a method of improving the suction performance in the normal state, the player is forced to play in a specific stop operation order (for example, pressing left → middle → right). There is known a penalty specification that imposes a penalty when a game is played with (see, for example, Patent Document 1).
In the internal lottery process of the penalty specification AT machine, the winning probability of a small push-order combination (hereinafter referred to as a small push-order combination A) for which the correct operation order is set other than the specific stop operation order is determined as follows. It is set to be higher than the winning probability of a small winning combination in pushing order (hereinafter referred to as a small winning combination in pushing order B) set in a specific stop operation order. During the normal state, the player proceeds with the game in the specific stop operation order so as not to be penalized. When the game is played in the specific stop operation order, the correct small winning combination with a large payout is not won, and as a result, the number of balls to be paid out in the normal state can be kept low.

Furthermore, there is also known a slot machine that changes stepwise the ball output performance in the AT state by stepwise changing the instruction frequency of the correct operation order in the pushing order minor win winning game in the AT state ( For example, see Patent Document 2).

JP 2017-000263 A JP 2021-079039 A

By the way, in the above-mentioned AT machine with the penalty specification, in order to change the ball output performance in the AT state in stages, in the pushing order small win winning game in the AT state, a predetermined number based on the current operation frequency setting is simply set. In the case of adopting a configuration in which the correct operation order is instructed with a probability of , in a game in which there is no instruction for the stop operation order during the AT state (hereinafter referred to as a game without instruction), the game is played in a manner other than the specific pressing order. However, there is a problem that the ball output performance becomes higher than when the game is advanced in the specific pressing order. This is because, as described above, the winning probability of the winning small winning combination A is higher than the winning probability of the winning small winning combination B in the penalty specification AT machine.
For example, in a game in which it is determined that a small winning combination is won during the AT state and the correct operation order is not instructed, by adopting a configuration that instructs other than the specific operation order or the correct operation order, it is possible to obtain balls. Although it is possible to suppress the performance, in this configuration, even if the instruction is followed, the winning of the correct small combination cannot be obtained, and as a result, the player is distrusted. , cannot be employed.

FIG. 8 shows a plurality of types of lottery divisions to be 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 combination that is a bonus combination and the replay 1 to 4 combinations are simultaneously won. In the slot machine 1, in a game in which a bonus combination and a minor combination or a bonus combination and a replay combination are won, reel stop control is adopted to win the small combination or the replay combination with priority over the bonus combination. In the game in which the bonus lottery category G1 is won, any one of the replay 1 to 4 roles wins, and the RB role does not win.

Each of the pushing order bell lottery categories G2 to G7 is a lottery category generally called a pushing order small combination. More specifically, when a plurality of types of small wins with different payouts are won in duplicate and the stop operation order matches the predetermined correct order of operation, the small win with the largest payout is won regardless of the stop operation timing. However, the lottery category is set so that if the stop operation order does not match the correct operation order, the small winning combination with the maximum payout will not win.
In a game in which one of the bell lottery categories G2 to G7 is won, if the stop operation order matches the correct operation order, the payout will be any of 10 bells 1 to 4, regardless of the stop operation timing. However, if it does not match the correct operation order, none of the bells 1 to 4 wins, and depending on the timing of the stop operation, one wrong answer bell 1 to 10 wins. Either wins or loses the prize.

The pressing order bell lottery category G2 is a lottery category in which bell 1 to 2 wins and incorrect bell 1 to 6 wins are duplicated, and the order of correct operation is set in the order of left→middle→right.
The pressing order bell lottery category G3 is a lottery category in which bell 3-4 combinations and incorrect bell 1-7 combinations are won, and the correct operation order is set in the order of left→right→middle.
The pressing order bell lottery category G4 is a lottery category in which bell 1, incorrect bell 1 to 6, and incorrect bell 8 are simultaneously won, and the order of correct operation is set in the order of middle → left → right. ing.
The pressing order bell lottery category G5 is a lottery category in which 2 bells, 1 to 6 incorrect bells, and 9 incorrect bells are won, and the correct operation order is set in the order of middle → right → left. ing.
The pressing order bell lottery category G6 is a lottery category in which 3 bells, 1 to 6 incorrect bells, and 10 incorrect bells are won, and the order of correct operation is set in the order of right → middle → left. ing.
The pressing order bell lottery category G7 is a lottery category in which 4 bell combinations and 1 to 9 incorrect bell combinations are won, and the correct operation order is set in the order of right→left→middle.

The rare minor combination lottery category G8 is a lottery category in which cherry 1 to 5 combinations are repeatedly won. In the game in which the rare small combination lottery category G8 is won, any one of the combinations of 1 to 5 cherries with a payout of 1 cherry wins or the winning combination fails depending on the timing of the stop operation.
The rare minor combination lottery category G9 is a lottery category in which a single watermelon combination is won. In the game in which the rare small combination lottery category G9 is won, the winning combination of four watermelons wins or the winning combination fails depending on the timing of the stop operation.

The replay lottery section G10 is a lottery section in which the replay 1st to 4th combinations are repeatedly won. In the game in which the replay lottery category G10 is won, one of the replay 1 to 4 roles is won regardless of the stop operation order and timing.

All minor role overlapping lottery category G11 is a lottery in which all minor roles, specifically, Bell 1 to 4, Incorrect Bell 1 to 10, Cherry 1 to 5, and Watermelon are won. It is a division. The all minor role overlapping lottery category G11 is a lottery category exclusively for RB games. Any one of 1 to 10 correct bells, 1 to 5 cherries, and watermelon will win a prize. Further, as described above, the prescribed number in the RB game is 2, and when the prescribed number is 2, the payout for all small wins 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 for the setting values 1 to 6 of the slot machine 1 will be described.
9 and 10 show the lottery value corresponding to the winning range of each lottery category for each set value. Since the range of random numbers in the internal lottery process is 0 to 65535, the winning probability of each lottery category for each set value can be calculated by lottery value/65536.

FIG. 9 shows lottery specifications for non-bonus RT0 and bonus internal RT1.
The lottery value of the bonus lottery category G1 is set to 16384 regardless of the set value, and the winning probability is set to 1/4. As described above, if the bonus lottery category G1 is won in non-bonus RT0, the game moves to internal bonus RT1. In RT1 during the bonus, if the bonus lottery category G1 is won, replays 1 to 4 will be won in duplicate.

The lottery values of the pressing order bell lottery categories G2 and G3 are respectively set to 4000 regardless of the set value, and the winning probability is set to about 1/16.38.
The lottery values of the pressing order bell lottery categories G4 to G7 are respectively set to 8000 regardless of the set value, and the winning probability is set to about 1/8.19.
The lottery value of the rare small winning lottery category G8 is 1600 when the set value is 1, 1660 when the set value is 2, 1768 when the set value is 3, 1884 when the set value is 4, and the set value is When the set value is 5, it is set to 1960, and when the set value is 6, it is set to 2048.
The lottery value of the rare small combination lottery category G9 is 546 when the set value is 1, 565 when the set value is 2, 585 when the set value is 3, 607 when the set value is 4, and the set value is When the set value is 5, it is set to 630, and when the set value is 6, it is set to 655, respectively.
The lottery value of the replay lottery category G10 is 7006 when the set value is 1, 6927 when the set value is 2, 6799 when the set value is 3, 6661 when the set value is 4, and 5 when the set value is 5. When the set value is 6, it is set to 6562, and when the set value is 6, it is set to 6449, respectively.
As a result of the internal lottery during RT0 during bonus non-internal and RT1 during bonus internal, there is no so-called loss in which no lottery division G1-G10 is won, and any lottery division G1-G10 is always won. It is configured as follows.

Further, as described above, in the slot machine 1, in a game in which a bonus combination and a minor combination or a replay combination are won, the reel stop control is adopted such that the minor combination or the replay combination is won with priority over the bonus combination. Since the internal lottery result during RT1 of the internal bonus does not result in a loss, the opportunity to win the RB role is the game won in the rare minor role lottery category G8 or the rare minor role lottery category G9 during the internal bonus RT1. This is limited to the case where the stop operation is performed aiming at the black bar pattern in the game in which the player wins. Therefore, it is extremely rare for the RB role to win in RT1 during the bonus period. Essentially, it will continue to stay at RT1 during the inside of the bonus.

FIG. 10 shows lottery specifications in the bonus game RT2.
In the internal lottery in the bonus game RT2, only the all small combination overlapping lottery category G11 is targeted for lottery, the lottery value is set to 65536 regardless of the set value, and the winning probability is set to 1/1. As described above, in the bonus game RT2, that is, in the RB game, in the game in which the all small combination overlapping lottery category G11 is won, regardless of the stop operation order and timing, Bell 1 to 4, incorrect Bell 1 to 10, Cherry One of the 1st to 5th hand and the watermelon hand is awarded, but as described above, the prescribed number in the RB game is 2, and in the case of the prescribed number of 2, the payout for all small winnings is set to 1. Therefore, the payout for winning is one. Also, 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 two inserted medals is repeated nine times and ended. It will be. Therefore, the RB game adopts a bonus that medals decrease, that is, the slot machine 1 adopts a so-called decreasing bonus specification.

Therefore, in the slot machine 1, in the RB game, 9 games in which one medal is lost are repeated, and as a result, only 9 medals are lost. be. In addition, as described above, the chance of winning the RB role is extremely rare, and unless the stopping operation is performed aiming at the black bar pattern when the winning opportunity arrives, the RB role will not win. is unlikely to win.

On the other hand, in a simulation test in a slot machine model certification test, a so-called bonus combination that once won is maintained in a winning state until winning is won in a winning game (hereinafter referred to as premise 1). As for the combination, regardless of whether or not the instruction function is activated, the maximum payout small combination is won in all winning games (hereinafter referred to as premise 2). Otherwise, it will be disqualified for the type approval test. Slot machines that do not pass the type approval test cannot be installed in halls.

The simulation test can be said to be a test assuming that there is no inside of the bonus from the above premise 1, and that all the stop operations are performed in the order of the correct operation at the time of winning the so-called pushing order role from the above premise 2. As described above, in the slot machine 1, the winning probability of the non-internal bonus RT0 in the bonus lottery section G1 including the RB role is 1/4. The number of staying games at RT0 is 4 games on average, the RB role wins in the winning game, and after winning the prize, 9 RB games are executed in which the number of medals is reduced by 9, and the loop of returning to RT0 during bonus non-internal again is repeated. It will be.
Therefore, from premise 2 above, the medal increase period in the simulation test is RT0 during non-bonus, but as described above, it ends in an extremely short period of 4 games on average, and the number of medals added per game is about 4. .Since it is set to 2 sheets (can be calculated from Figures 8 and 9), it is designed so that it will not fail the type test in the simulation test.

According to gaming machine-related regulations, the bonus game is a period during which the odds of winning small wins can be varied, and is originally defined on the assumption that it will be used as a more advantageous gaming period than during normal times other than during the bonus game. Therefore, the winning probabilities of all small wins in the bonus game need to be improved compared to normal times. In the slot machine 1, the probability of winning each small combination during the RB game is 1/1, which is higher than the winning probability of each small combination of non-bonus RT0 and bonus internal RT1. meets the requirements of In this way, the slot machine 1 realizes the reduced bo by an extremely simple method.

In addition, without changing the specified number even during the bonus, among a plurality of small winning combinations normally included in a plurality of lottery categories, small winning combinations with the same dividend are grouped into one lottery category and simultaneously won and combined. By using the conventional method of realizing a decreasing ball by making the empty numerical range in the internal lottery that occurred in The winning probability of the correct small win lottery category obtained by combining the above into one must also be higher than the winning probability of the winning probability of the lottery category with the highest winning probability among the plurality of types of pushing order small wins.
As shown in FIG. 9, the present slot machine 1 adopts a penalty specification with biased winning probabilities for pushing order bells G2 to G7. The lottery value of the lottery category must 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 that is adopted to increase the net increase in the AT period. The higher the probability of winning a small winning combination (hereinafter referred to as a penalized small winning combination), the better.
Therefore, when the conventional method of decreasing bonuses is applied to a slot machine with penalty specifications, the winning probability of the correct small winning combination lottery category in the bonus is reduced due to the high probability of winning the winning small winning winning combination subject to the penalty. As a result, the desired suction performance may not be obtained during the bonus.

On the other hand, in place of the conventional decreasing bo method, according to the new decreasing bo method adopted in the slot machine 1, it is extremely easy regardless of the winning probability of the normal penalty push order small combination and the payout of the correct small combination. In this way, you can achieve a bonus that reduces by one card each game. At the stage of designing a slot machine, if a bonus of one or more cards reduced every game can be realized when adopting the conventional method of decreasing Boss, the conventional method of decreasing Boss can be used. The new method of decreasing Boss adopted in the slot machine 1 may be used.

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

<5-1. Game state flow related to instruction function>
11A and 11B are diagrams showing game state transitions related to the instruction function in the slot machine 1. FIG.

A game 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 operated and an advantageous state in which the instruction function can be operated. When the instruction function is activated, in a game in which any one of the pressing order bells G2 to G7 is won, a command for instructing the correct operation order is transmitted from the main control device 100a to the effect sub-controller 100b, and an instruction monitor. Identification information corresponding to the correct operation order is displayed on the NM. The effect sub-controller 100b informs the player of the correct operation order by displaying on the liquid crystal display 30 and by outputting sound from the speakers 31, 31 according to the instruction command from the main controller 100a. The act of the main controller 100a displaying the identification information on the instruction monitor NM and transmitting the instruction command to the effect sub-controller 100b is called the operation of the instruction function.
During the non-advantageous state, the advantageous section lamp YL is turned off, an advantageous state transition lottery is executed according to the result of internal lottery processing, and when the advantageous state transition lottery is won, the state is shifted to the advantageous state.

The advantageous states consist of 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 transition lottery, first, the game is shifted to the first advantageous state.
Then, in the first advantageous state, when the AT state transition lottery is won or when the AT state transition lottery is not won and the number of executed games reaches the ceiling number of games, the state is shifted to the AT state. The advantageous section lamp YL is switched from the off state to the on state along with the transition to the AT state.
Then, when the AT state ends, it falls to a non-advantageous state, and the advantageous section lamp YL is also turned off from the lighting state along with this.

In addition, the slot machine 1 is equipped with a limiter function relating to an advantageous state. Specifically, the limiter function is when the number of games executed during an advantageous state reaches 1500, or when the difference number during an advantageous state (the difference between the number of medals obtained during an advantageous state and the number of medals inserted) is 2400. is exceeded, the advantageous state is forcibly ended and a non-advantageous state is entered.
Therefore, the AT state ends when the right to continue the AT state, specifically, when the number of remaining games or the number of set stocks is exhausted, or when the limiter function is activated.

Game control related to the instruction function will be described below.
As described with reference to FIG. 6, the RT state of the slot machine 1 is any one of RT0 to RT3. Of these, RT0 during non-bonus is the RT state after setting change. When the setting is changed, the game state related to the instruction function is also changed to a non-advantageous state. In addition, the above-mentioned advantageous state transition lottery is not performed in the non-bonus RT0.
Therefore, the state does not change to an advantageous state while staying at RT0 during non-bonus period, and the non-advantageous state is assumed during stay at RT0 during non-bonus period.

Then, on the condition that the bonus lottery category G1 is won at RT0 during non-bonus operation and shift to RT1 during bonus operation, various lottery processing related to the instruction function including the above-mentioned advantageous state transition lottery is executed. and

<5-2. Unfavorable state>
FIG. 12 is a flow chart showing the flow of processing when the slot machine 1 is in a non-advantageous state.
During the non-advantageous state, first, in step S1201, an internal lottery process is executed, and in step S1202, it stops in the order of left→middle→right or left→right→middle (hereinafter collectively referred to as left 1st). Determine if an operation was performed. When it is determined as 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 lottery has been won in the advantageous state transition lottery process of step S1203. If it is determined to be YES, then in step S1205 the advantageous state start process is executed, and then the first advantageous state is entered. In order to start, in step S1206, the first advantageous state process is started and the process returns.
Specifically, the advantageous state transition lottery process in step S1203 is executed in a game in which one of the lottery categories G1 to G7 is won as a result of the internal lottery process, and the winning probability is set to 50%. In addition, in the advantageous state start processing of step S1205, various initialization processing necessary at the time of starting the advantageous state, such as initialization processing of various counters such as the number of executed games during the above-described advantageous state and the difference number, etc., is executed.

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 transition lottery process in step S1203 is not performed as a penalty. Therefore, in this case, the process returns to step S1201 to continue the non-advantageous state.

<5-3. First Advantageous State>
FIG. 13 is a flow chart showing the flow of processing during the first advantageous state of the slot machine 1. FIG.
During the first advantageous state, first, in step S1301, an internal lottery process is executed, and in step S1302, it is determined whether or not a stop operation has been performed on the left 1st. If it is determined 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 the left 1st, the AT state transition lottery process of step S1303 is skipped as a penalty, and the process proceeds to step S1304. Description of the details of the AT transfer lottery process is omitted.
At step S1304, the number of games played is incremented by one, and at the next step S1305, it is determined whether or not the number of games played has reached the ceiling number of games. Note that the number of games played is set to zero as an initial value in the advantageous state start process (S1205).
If NO in step S1305, it is determined in step S1306 whether or not the lottery has been won in the AT state transition lottery process in step S1303, and if yes, the process proceeds to step S1307. Also when it is judged as YES in step S1305, it transfers to step S1307. In step S1307, in order to start the AT state, the 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 to continue the first advantageous state.

<5-4. AT state (second advantageous state)>
FIG. 14 is a flow chart showing the flow of processing during the AT state (second advantageous state) of the slot machine 1. FIG.
During the AT state, first, in step S1401, an internal lottery process is executed, and in step S1402, it is determined whether or not any of the pressing order bells G2 to G7 has been won. If it is determined YES in step S1402, that is, in a game in which one of the pressing order bells G2 to G7 is won, the processing of steps S1403 to S1406 is performed, which will be described later. On the other hand, if NO is determined in step S1402, the process proceeds to step S1407.
In step S1407, depending on the internal lottery result, a parameter (hereinafter referred to as AT continuation right) that is consumed as a consideration for AT state continuation and AT ends when consumed is executed. will add the AT continuation right. 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 or not to upgrade to the high net increase mode. Instruction mode will be described later. In the next step S1409, it is determined whether or not to continue the AT state by confirming whether or not there is an AT continuation right and whether or not the limiter operation condition is satisfied. While the AT state is continued, when it is determined to be NO, in step S1410, after executing the advantageous state end processing, in step S1411, the processing in the non-advantageous state is started and the process returns. Specifically, in the advantageous state end processing, all information related to the instruction function used for controlling the advantageous state to be ended is cleared.

<5-4-1. Processing when pressing order bell G2 to G7 is won>
Next, the processing of steps S1403 to S1406 will be described.
The instruction mode of the slot machine 1 refers to the operation mode of the instruction function when winning the pressing order bell G2 to G7 in the AT state. The instruction mode at the start of the AT state is the low net increase mode, and after winning the mode-up lottery process in step S1408, the high net increase mode is used. be done.

At step S1403, it is determined whether or not the instruction mode is the low net increase mode.If NO, that is, if the high net increase mode is selected, steps S1404 and S1405 are skipped and the process proceeds to step S1406. On the other hand, if it is determined YES in step S1403, that is, in the case of the low net increase mode, instruction execution lottery processing is executed in step S1404. In the next step S1405, it is determined whether or not the lottery is won in the instruction execution lottery process, and if yes, the process proceeds to step S1406. The process moves to step S1407. In step S1406, the instruction function is activated to inform the correct operation order, and the process proceeds to step S1407.

<5-4-2. Instruction Execution Lottery Processing>
FIG. 15 shows the contents of the instruction execution lottery process.
As described above, the slot machine 1 adopts the penalty specification. The winning probability of the pressing order bells G4 to G7 set to 1 is as high as 8000/65536.
For this reason, for example, if an instruction execution lottery is performed with a uniform probability even if any of the pressing order bells G2 to G7 is won, the pressing order bell will not be displayed even in a game in which no instruction is determined (hereinafter referred to as a no-instruction game). The probability of winning G4 to G7 is higher than the probability of winning pushing order bells G2 and G3. That is, in the non-instruction game, the stop operation performed in the order other than the left 1st order has a higher probability of matching the correct operation order than the case where the stop operation is performed in the left 1st order. Therefore, in the AT state no instruction game, there is a problem that unfairness occurs between the player who performs the stop operation in the order other than the left 1st order and the player who performs the stop operation in the left 1st order.

Therefore, in the slot machine 1, in order to solve this problem, the pressing order bell G2 to In consideration of the probability of winning for each G7, the probability of winning the instruction execution lottery is determined for each of the pressing order bells G2 to G7.
Specifically, as shown in FIG. 15, the instruction execution lottery winning probability in the game in which the pushing order bells G2 and G3 are won is 50%, and the instruction execution lottery winning probability in the game in which the pushing order bells G4 to G7 are won is 50%. Each was set to 75%.

As a result, the no-instruction probability of the game without instruction can be the same 2000/65536 in games in which any of the bells G2 to G7 in the order of pressing is won. Even if it does, the probability of matching the correct operation order can be the same. As a result, the payout expected value in the non-instruction game can be made uniform 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 in the whole winning game of the pressing order bell G2 to G7 is set to 70%.

As described above, according to the instruction execution lottery method of the slot machine 1, in the AT machine of the penalty specification that changes the ball output performance in the AT state step by step, the player can select which one in the game without instructions. Even if the stopping operation is performed in the order of operation, unfairness does not occur due to the order of the stopping operation, and the ball payout performance as designed can be realized.

Although the embodiments of the present invention have been described above, the present invention can be modified in various ways within the scope of the claims.
