Description

  As a medal increase period in a slot machine, a bonus game and an assist replay time (hereinafter referred to as ART) are conventionally known. Specifically, during the ART, the player is instructed with information necessary for winning a relatively advantageous combination among the internal winning combinations. For this reason, hereinafter, the ART function is also referred to as an instruction function.

The bonus game is started based on 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, as a countermeasure against the “reluctant” problem, there has been a demand for a gaming machine having an appropriate shooting ability. As a method for realizing a gaming machine having an appropriate shooting ability, a method of compensating a part of the outgoing balls during the holding ball increasing period of the conventional gaming machine as a holding ball decreasing period, that is, a normal ball outgoing game can be considered. This makes it possible to realize a gaming machine with an appropriate shooting ability, in which a large amount of balls as in the conventional case cannot be expected during the holding ball increase period, instead of having a ball holding better than usual in the normal state.

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.

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.

  In addition, as an advantageous state, in the game state except RT1, (RT0, RT2, and RT3), the first advantageous state in which the 100% correct pushing order is notified in the game won in the lottery groups GRP3 to GRP14, and the first advantageous state A second advantageous state in which the correct pressing order is notified at a lower frequency than the state. On the other hand, in the normal state, the game in which the lottery groups GRP3 to GRP14 are won is not notified of the correct pressing order.

<1. Normal state>
FIG. 12 shows the flow of the game process in the normal state.
First, an internal lottery process is executed in step S1201, and in the next step S1202, it is determined whether or not the current gaming state is during RT3, during the BB1 game, or during the BB2 game.
In the normal state, during RT3, during the BB1 game, and during the BB2 game, it is set as a period during which it is not determined whether or not to shift to the advantageous state. If it is determined YES in step S1202, the process proceeds to step S1201. Return.

On the other hand, if it is determined NO in step S1202, that is, if the current gaming state is RT0 to RT2, the process proceeds to step S1203 to determine whether or not the lottery group GRP15 has been won. If it is determined, the advantageous state transition lottery process is performed in the next step S1204.
The specific lottery contents of the advantageous state transition lottery process are shown in FIG.

  As shown in FIG. 13 (a), the advantage state transition lottery process is executed only in a game that has won one of the lottery groups GRP15 (cherry), GRP19, and GRP20 as a result of the internal lottery process in the normal state. It is skipped in the game that won the lottery group and the game that lost.

The winning probability in the advantageous state transition lottery process is set to 20% for the game won in the lottery group GRP15 (Cherry) and 100% in the game won for the lottery groups GRP19 and GRP20.
In addition, in the game won in the lottery group GRP15 (Cherry), when winning the advantageous state transfer lottery process, the game moves to the first advantageous state, while in the game won in the lottery groups GRP19 and GRP20, FIG. As shown in FIG. 4, the game is shifted to either the first advantageous state or the second advantageous state according to the winning result of the game. This will be described later.

  Returning to FIG. 12, in the next step S1205, it is determined as a result of the advantageous state transition lottery process in step S1204 whether or not it has been won. If it is determined to be yes, the next advantageous state is in the next step S1206. The process starts and ends. On the other hand, if NO is determined in step S1205, the process returns to step S1201.

If NO is determined in step S1203, it is determined whether or not the lottery group GRP19 or GRP20 is won in step S1207. If NO is determined, the process returns to step S1201.
On the other hand, if it is determined as YES in step S1207, it is determined whether or not replay 6 (watermelon RP) is won in the game in the next step S1208. If YES is determined, step S1206 is determined. In step S1209, the process in the second advantageous state is started and the process ends.

  As shown in FIGS. 13 (a) and 13 (b), in the game won in the lottery group GRP19 during the normal state, when the replay 6 (watermelon RP) wins in the game, the first advantageous state, the replay When 7 (watermelon zero RP1) wins, it is supposed to shift to the second advantageous state. Also, in a game won in the lottery group GRP20 during the normal state, when the replay 6 (watermelon RP) wins in the game, the first advantageous state, the replay 8 (watermelon zero and RP2) wins Is to be shifted to the second advantageous state.

If the transition to the first advantageous state is determined, the lottery of the initial set game number and the initial set continuation rate is performed next. Here, the set continuation rate indicates the probability of starting the next set continuously after the end of the set.
FIG. 13C shows a lottery method for the number of initial set games and the initial set continuation rate.
As shown in FIG. 13C, 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 59.5%.

  If it is decided to shift to the second advantageous state, the lottery of the longest number of games is performed next. Here, the longest number of games indicates the longest number of games in which the second advantageous state continues. FIG. 13D shows a lottery method for the longest number of games. The longest number of games is 100 games at 10% allocation rate, 200 games at 10% allocation rate, 300 games at 10% allocation rate, 400 games at 10% allocation rate, 60% allocation The rate is 500 games.

<2. First advantageous state>
FIG. 14 shows the flow of the game process during the first advantageous state.
First, in step S1401, 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 S1402, an internal lottery process is executed. In response to this, in the next step S1403, 1 is added to the number of advantageous games and 1 is subtracted from the number of set games.
In the next step S1404, whether it is staying in RT3 (inside the bonus), in the BB1 game, or in the BB2 game is determined, and if it is determined to be no, that is, if it is staying in RT0 to RT2, In step S1405, the continuation rate is added and the lottery process is executed. On the other hand, if it is determined yes, step S1405 is skipped and the process proceeds to step S1406.

FIG. 15 shows the details of the lottery process for adding the continuation rate.
The continuation rate extra lottery process is executed when the lottery groups GRP3 to GRP15 are won as a result of the internal lottery process.

FIG. 15A shows the contents of the lottery with the continuation rate added.
As shown in FIG. 15A, in a game won in any of the lottery groups GRP 3 to 14, the continuation rate is increased by 5% with a winning probability of 1%.
In addition, in the game won in the lottery group GRP15, the continuation rate is increased by 20% at the allocation rate of 25%, the continuation rate is increased by 10% at the allocation rate of 25%, and the continuation rate at the allocation rate of 50%. Will be added 5%.

  Returning to FIG. 14, in the next step S1406, it is determined whether or not the lottery groups GRP3 to 14 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 S1407. If NO is determined in step S1407, the correct push order is notified in the next step S1408 and the process proceeds to step S1409. If YES is determined, that is, if the user is staying at RT0. In order to shift to RT1, step S1408 is skipped and the process shifts to step S1409. Also when it is determined NO in step S1406, the process proceeds to step S1409.

In step S1409, it is determined whether or not the lottery groups GRP16 to 18 are won. If it is determined that the answer is YES, it is determined whether or not the user is staying at RT1 in step S1410. If it is determined as YES in step S1410, in the next step S1411, the correct answer push order is notified to shift to RT2, and the process shifts to step S1412.
When it is determined NO in step S1409 and when NO is determined in step S1410, the process also proceeds to step S1412.

In step S1412, 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 S1413 whether or not the number of set games has reached zero. If NO in step S1413, the process returns to step S1402 to continue the first advantageous state.
On the other hand, if it is determined YES in step S1413, a set continuous lottery process is executed in step S1414. 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 S1415, it is determined whether or not the winning is made in the set continuation lottery process. If the determination is yes, the next set game number and continuation rate are determined in step S1418 to start the next set. Execute the process.

FIG. 15B shows the content of the next set game number and continuation rate determination process.
As shown in FIG. 15 (b), the next set number of games is 30 games, and the next set continuation rate is 50% at a 35% allocation rate, 60% at a 40% allocation rate, and 20% allocation. The rate is 70% and the allocation rate is 5% and 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%.

Returning to FIG. 14, when it is determined YES in step S1412, and when NO is determined in step S1415, the first advantageous state ending process is executed in step S1416 to end the first advantageous state. In the next step S1417, the process is shifted to the normal state process and the process is terminated.
Specifically, in the first advantageous state termination process, the advantageous state lamp YL is turned off, and the area on the RAM 43 in which various variables relating to the control in the advantageous state are stored is cleared.

<3. Second advantageous state>
FIG. 16 shows the flow of game processing during the second advantageous state.
First, in step S1601, the advantageous state lamp YL is turned on, the advantageous number of games is set to zero, and the remaining number of games is set to the longest number of games 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 remaining number of games.
In the next step S1604, it is determined whether or not the user is staying at RT3 (inside the bonus), BB1 game, or BB2 game. If NO is determined, that is, if the user is staying at RT0 to RT2, In step S1605, the remaining game number reduction lottery process is executed. On the other hand, if it is determined that the answer is yes, step S1605 is skipped and the process proceeds to step S1606.

The contents of the remaining game number shortening lottery process are shown in FIGS.
The remaining number-of-games reduction lottery process is executed for a game that has won the lottery group GRP15, GRP19 or GRP20 during the second advantageous state while staying at RT0 to RT2.
As shown in FIG. 17A, in the game won in the lottery group GRP15, 50 games with 80% allocation rate, 100 games with 10% allocation rate, 150 games with 7% allocation rate, 3% It is assumed that 200 games and the remaining number of games will be shortened with the allocation rate of.

In the game won by the lottery group GRP19 or GRP20, as shown in FIG. 17 (b), the process branches according to the winning result of the game.
Specifically, in a game in which the lottery group GRP19 or GRP20 is won and the replay 6 (watermelon RP) wins, regardless of the current number of remaining games, the remaining number of games is reset to zero, so that The advantageous state is to be terminated.
On the other hand, in the game in which replay 7 (watermelon zero RP1) is won by winning the lottery group GRP19 and in the game in which replay 8 (watermelon zero RP2) is won by winning the lottery group GRP20, FIG. The same process as that of the game won in the lottery group GRP15 shown in FIG.

  Returning to FIG. 16, in the next step S1606, it is determined whether or not the lottery groups GRP3 to GRP14 have been won. If it is determined that the answer is YES, a correct push order notification lottery process is executed in step S1607. Specifically, the winning probability of the correct push order notification lottery process is set to 20%. In the next step S1609, it is determined whether or not winning is made in the correct answer push order notification lottery process in step S1607. If YES is determined, the correct answer push order is notified in step S1609, and the process proceeds to step S1610. . When it is determined NO in step S1606 and when NO is determined in step S1608, the process also proceeds to step S1610.

  Therefore, during the second advantageous state, in the game won in the lottery groups GRP3 to GRP14, the correct answer push order is notified at a rate of once every five times. In comparison with the first advantageous state in which the correct push order is notified in almost all games won in the lottery groups GRP3 to GRP14, it is disadvantageous for the player, but almost all games won in the lottery groups GRP3 to GRP14. In comparison with the normal state in which the notification of the correct push order is not performed, it is advantageous for the player.

  In addition, the normal state and the second advantageous state are the holding ball reduction period except during the BB1 and BB2 games. For the above reason, the holding ball is reduced in the second advantageous state compared to the normal state. The degree is suppressed.

  In the next step S1610, it is determined whether or not the number of advantageous games has reached 1500 games. If it is determined as no, it is determined in the next step S1611 whether or not the remaining number of games has become zero or less. If NO is determined in step S1611, the process returns to step S1602.

If YES is determined in step S1610, and if YES is determined in step S1611, the second advantageous state ending process is executed in step S1612 to end the second advantageous state, and the next step S1613 is executed. To shift to the normal state process and finish the process.
Specifically, in the second advantageous state end processing, the advantageous state lamp YL is turned off, and the area on the RAM 43 in which various variables relating to the control in the advantageous state are stored is cleared.

As described above, the slot machine 1 of the above embodiment has the first advantageous state in which the correct push order is notified in almost all the games won in the lottery groups GRP3 to GRP14 as the advantageous state in which the instruction function is valid. And a second advantageous state in which the notification frequency of the correct push order is lower than that in the first advantageous state.
The first advantageous state is the ball increasing period, the second advantageous state, and the normal state where the instruction function is not activated are the ball decreasing period.

  In the second advantageous period, as described above, in the game won in the lottery groups GRP3 to GRP14, the notification of the correct pressing order is performed at a rate of once every five times. Although it is necessary to operate 20L, 20C, and 20R, if this operation is performed, since the degree of decrease of the holding ball is suppressed as compared with the normal state, the holding of the ball is improved as compared with the conventional slot machine. You can play longer with a fixed investment.

  In addition, the first advantageous state and the second advantageous state are shifted only from the normal state, and after the first advantageous state and the second advantageous state are finished, the normal state is restored. In other words, the transition between the first advantageous state and the second advantageous state always passes through the normal state. That is, since there is no direct transition from the second advantageous state to the first advantageous state, the normal state is more advantageous than the second advantageous state in terms of the transition to the first advantageous state.

Furthermore, in the game in which the lottery group GRP19 or GRP20 is won in the normal state, the game is determined as to which of the first advantageous state and the second advantageous state is substantially determined by the operation timing of the right stop button 20R. Therefore, the game can be a very hot game for the player.
Similarly, even in a game won in the lottery group GRP19 or GRP20 in the second advantageous state, whether or not the second advantageous state can be ended in the game substantially by the operation timing of the right stop button 20R. The game is determined.

  In the second advantageous state, there is no chance to shift to the first advantageous state as in the normal state, but in addition to the fact that the ball has better than the normal state, the chance of shortening the number of remaining games, and the normal state regardless of the number of remaining games There is also a chance to return to the normal state, and even if such a chance is not obtained, if the number of games in the second advantageous state reaches the longest number of games, it can return to the normal state. It has different attractive features. For this reason, it can prevent effectively that a player stops a game at the time of shifting to the 2nd advantageous state.

  On the other hand, in the normal state, which is another period in which the ball is decreased, the ball holding is worse than in the second advantageous state, but it is a chance zone for shifting to the first advantageous state, so it is difficult to stop the game. It is also possible to effectively prevent the player from stopping the game.

  In addition, the slot machine 1 is equipped with a limiter function that sets the maximum number of continued games in an advantageous state in which the instruction function is effective to 1500 games in order to make the shooting property moderate. As described above, the slot machine 1 is equipped with two advantageous states, the first advantageous state and the second advantageous state, which have different operation frequencies of the instruction function. When shifting to the advantageous state, the normal state is always passed. Therefore, the maximum number of continued games in the first advantageous state during the holding ball increasing period is 1500 games, and the specification is not affected by the number of continuing games in the second advantageous state during the holding ball decreasing period.

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 above embodiment, two types of advantageous states of the first advantageous state and the second advantageous state having different operation frequencies of the instruction function are mounted, and it is always normal when a transition is made from one advantageous state to the other advantageous state. Although it has been through the state, it is not always necessary to reduce the normal state, and it is also possible to adopt a specification that allows mutual transition.

  However, when this specification is adopted, the maximum number of continued games in the first advantageous state that is the increase period of the ball is affected by the number of continuous games in the second advantageous state that is the decrease period of the ball However, it can be adopted in a slot machine in which the influence of the above disadvantages can be ignored, such as a slot machine in which the main ball increasing period is a bonus game.

  Further, in the slot machine 1 described above, the end and continuation of the first advantageous state is increased by adding the continuation rate to the initial continuation rate according to the game result in the first advantageous state. Although the so-called continuation rate addition type specification is adopted for a longer period of time, instead of this, the number of games is increased by adding the number of games to the initial number of continuous games according to the game result in the first advantageous state. It is also possible to adopt a so-called extra number type specification that prolongs the advantageous state.
