Abstract

Provided is a slot machine that can make a parameter related to a lottery process related to an instruction function common regardless of a set value, and can make a ball performance according to the instruction function according to the set value. SOLUTION Six winning combinations (watermelon RP) having a common winning probability regardless of a set value are used as a winning role set to 100% as a trigger for an advantageous state transition lottery. The reason for the transition to RT6 where the winning probability of the replay 6 role (watermelon RP) is relatively high is that the lottery group GRP2 having a different winning probability according to the set value, that is, winning the BB2 role and after winning the BB2 role During the BB2 game, it is limited to the case where the lottery group 25 having different winning probabilities according to the set value, that is, the RB2 combination is won. Since the probability of shifting to RT6 increases as the set value increases, it is possible to make the pitching performance related to the instruction function in accordance with the set value.

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.

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

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

  On the other hand, as a countermeasure against the “reluctant” problem, a gaming machine having an appropriate shooting ability has been conventionally demanded, and various measures are currently being examined in the gaming machine industry. As one of these measures, although there is no definition related to the above-mentioned instruction function in the current rules relating to gaming machines, it is considered that the instruction function is practically applicable, and there are certain restrictions on the instruction function. It is being considered.

  Specifically, in the past, lottery processing related to the instruction function was performed not by the main control device that controls the game control but by the sub control device that mainly controls the effect control related to the game. We decided to do it with the control device.

  In this industry, as a result of testing at a designated testing organization, only gaming machines that are determined to conform to the rules related to gaming machines are allowed to be installed in the hall. Is strictly scrutinized. In order to improve test efficiency, a certain limit is imposed on the storage capacity of the main controller.

JP 2014-23648 A

However, in performing the lottery processing related to the instruction function in the main control device, as described above, a certain limit is imposed on the storage capacity related to the main control device. The capacity should be as small as possible.
As a method for realizing this, there may be considered a method in which parameters related to the lottery process related to the instruction function, specifically, the winning probability or the like is made common regardless of the set value, but when this method is adopted, the output related to the instruction function is considered. There is a problem that the ball performance is constant regardless of the set value.

  With regard to the game performance of gaming machines, the hall has been operated by selecting a set value in consideration of the financial condition and management policy, and the ball performance related to the instruction function has been made constant regardless of the set value. In this case, such conventional operation becomes difficult and may cause confusion.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a slot machine that can make the ball performance according to the instruction function in accordance with the set value while making the parameters related to the lottery processing related to the instruction function common regardless of the set value.

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.

Based on the number of outputs, the rotational positions of the left reel 4L, middle reel 4C, and right reel 4R are always grasped.

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

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

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

When the set value is 1, the lottery value of the lottery group GRP24 is 24576, the winning probability is about 1 / 2.67, when the set value is 2, 20480, the winning probability is about 1 / 3.2, the set value If the value is 3, the winning probability is about 1/4, the setting value is 4, and the setting value is 12,288, the winning probability is about 1 / 5.33, the setting value is 5, 10240, the winning probability is about If the setting value is 1 / 6.4 and 6 is set to 8192, the winning probability is set to about 1/8.
The lottery value of the lottery group GRP25 is 8192 when the setting value is 1, its winning probability is about 1/8, 10240 when the setting value is 2, its winning probability is about 1 / 6.4, and the setting value is 3. In this case, the winning probability is about 1 / 5.33, if the set value is 4, 16384 if the set value is 4, the winning probability is about 1/4, if the set value is 5, 20480, the winning probability is about 1 / 3.2, if the set value is 6, 24576, the winning probability is set to about 1 / 2.67.
Accordingly, the winning probability of the lottery group GRP24 is the highest at the set value 1 and becomes lower as the set value becomes larger, while the winning probability of the lottery group GRP25 becomes the lowest at the set value 1 and becomes higher as the set value becomes larger. Is set to

  On the other hand, regarding the lottery group GRP26, the lottery groups GRP16 to 18, and the lottery group GRP22, the lottery value, that is, the winning probability is constant regardless of the set value. Specifically, the lottery value of the lottery group GRP26 is 16382, the winning probability is about 1/4, the lottery values of the lottery groups GRP16 to 18 are each 5362, the winning probability is about 1 / 12.2, and the lottery group GRP22 lottery. The value is 300, and the winning probability is set to about 1 / 2188.5.

FIG. 11C shows a lottery value corresponding to the winning range of each lottery group during the RB2 game during the BB2 game and during the RB1 game after winning the RB2 role at least once.
During the game, the lottery group GRP26, the lottery group GRP23 that the replay 7 wins alone, and the lottery group GRP22 are selected for the lottery group. Any of the lottery groups GRP26, GRP23, and GRP22, the lottery value, that is, the winning probability is constant regardless of the set value. The lottery value is set to 16086, the winning probability is set to about 1 / 4.07, the lottery group GRP22 lottery value is set to 300, and the winning probability is set to about 1 / 2188.5.

FIG. 11D shows a lottery value corresponding to the winning range of each lottery group in the general game in the BB2 game after winning the RB2 combination at least once in the BB2 game.
During the general game, the lottery group GRP24, the lottery group GRP25, the lottery group GRP26, the lottery group GRP23, and the lottery group GRP22 are subjected to lottery.
Note that the lottery values of the lottery group GRP24 and the lottery group GRP25 are the same as those described with reference to FIG. 11B, and the lottery values of the lottery group GRP26, the lottery group GRP23, and the lottery group GRP22 are illustrated in FIG. Is the same as the content described with reference to FIG.

FIG. 11E shows a lottery value corresponding to the winning range of each lottery group during the RB1 game in which the RB2 role is not won even once during the BB2 game.
During the game, the lottery group GRP26, the lottery groups GRP16 to 18 and the lottery group GRP22 are subjected to lottery.
The lottery value of the lottery group GRP26 is the same as the content described with reference to FIG. 11C, and the lottery groups GRP16 to 18 and the lottery group GRP22 are the same as the content described with reference to FIG. Therefore, explanation is omitted.

  When attention is paid only to the re-game players in FIGS. 11B to 11E, in the start state of the BB2 game, winning of the four lottery groups GRP 16 to 18 and GRP 22 shown in FIG. 11B may be permitted. When the first replay lottery state is entered and then the RB2 combination is won, winning of the two lottery groups GRP23 and GRP22 may be permitted as shown in FIGS. 11 (c) and 11 (d). Transition to 2 re-game lottery state. After the transition to the second re-game lottery state, the second re-game lottery state is maintained until the end of the BB2 game. On the other hand, when the RB2 combination is not won during the BB2 game, the first re-game lottery state that is the start state of the BB2 game is maintained.

  Also, as shown in FIG. 8, after the end of the BB2 game, if the RB2 role is won during the BB2 game, the process proceeds to RT5, and if the RB2 role is not won, the process proceeds to RT4. It is said. Here, referring to FIG. 9, when attention is paid only to the re-playing combination of RT5 and RT4, it can be seen that the second re-game lottery state is maintained in RT5 and the first re-game lottery state is maintained in RT4. That is, it can be seen that the re-game lottery state at the end of the BB2 game is maintained even after the BB2 game ends.

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

<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 an advantageous state shift lottery process is executed in the next step S1202 according to the result of the internal lottery process. The specific lottery contents of the advantageous state transition lottery process are shown in FIG.
As shown in FIG. 13A, in the advantageous state transition lottery process, as a result of the internal lottery process in the normal state, one of the lottery groups GRP1 (BB1 role), GRP15 (cherry), and GRP22 (watermelon RP) is won. It is executed only in the game, and is skipped in the game won in other lottery groups and the game that is lost. Even during the normal state, the advantageous state transition lottery process is not executed during the RT3, BB1 game, and BB2 game inside the bonus.

  The winning probability in the advantageous state transition lottery process is set to 10% for the game won in the lottery group GRP1, 20% for the game won in the lottery group GRP15 (Cherry), and 100% in the game won in the lottery group GRP22. Yes.

When winning in the advantageous state transition lottery process, the lottery of the first 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. 13B shows a lottery method of the initial set game number and the initial set continuation rate.
As shown in FIG. 13B, 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%.

  Returning to FIG. 12, in the next step S1203, it is determined as a result of the advantageous state transition lottery process whether or not the player has won. If YES is determined in step S1203, the process proceeds to the advantageous state process in step S1204, and the normal state process is terminated. If NO is determined, the process returns to step S1201.

<2. Advantageous state>
FIG. 14 shows the flow of the game process during the 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, it is determined whether or not RT3 (inside the bonus), and if it is determined to be no, in the next step S1405, the continuation rate is added and a lottery process is executed. Skips step S1405 and proceeds to step S1406.

FIG. 15 shows the details of the lottery process for adding the continuation rate.
In the continuation rate extra lottery process, the continuation rate to be added is set according to the internal lottery process result.
Specifically, the continuation rate increase lottery process is executed when the lottery group GRP1, GRP15, or GRP22 is won as a result of the internal lottery process.

FIG. 15A shows the contents of the continuation rate extra lottery when winning the lottery group GRP1 or GRP15, and FIG. 15B shows the contents of the continuation rate extra lottery when winning the lottery group GRP22.
As shown in FIG. 15 (a), when winning the lottery group GRP1 or GRP15, the continuation rate is increased by 20% at the allocation rate of 25%, and the continuation rate is increased by 10% at the allocation rate of 25%. The continuation rate is increased by 5% at a distribution rate of 50%.

  On the other hand, when winning the lottery group GRP22, as shown in FIG. 15B, the continuation rate is increased by 20% at a distribution rate of 20%, and the continuation rate is increased by 10% at a distribution rate of 20%. The continuation rate is increased by 5% at a distribution rate of 60%.

  Returning to FIG. 14, in the next step S1406, it is determined whether or not the lottery groups GRP 3 to 14 have been won. . 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, skip step S1408 and shift to step S1409 to shift to RT0 when staying at RT4. 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 is determined in step S1413, the process returns to step S1402 to continue the 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. 15C shows the contents of the next set game number and continuation rate determination processing.
As shown in FIG. 15 (c), 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, if it is determined YES in step S1412, or if NO is determined in step S1415, an advantageous state end process is executed in step S1416 to end the advantageous state. In S1417, the process is shifted to the normal state process and the process is terminated.
Specifically, in the advantageous state end process, an advantageous state lamp YL is turned off, and an area on the RAM 43 in which various variables relating to the control during the advantageous state are stored is performed.

As described above, in the slot machine 1 of the above-described embodiment, the lottery process related to the instruction function is executed on the condition of winning a predetermined lottery group having a constant winning probability regardless of the set value.
Specifically, as shown in FIG. 13 (a), the advantageous state transition lottery process relating to whether or not to shift from the normal state in which the instruction function is disabled to the advantageous state in which the instruction function is enabled, As a result of the internal lottery process in the state, it is executed based on winning the lottery group GRP1, GRP15 or GRP22.
Similarly, in the continuation rate addition lottery for adding the continuation rate during the advantageous state, as shown in FIGS. 15A and 15B, as a result of the internal lottery process during the advantageous state, the lottery groups GRP1, GRP15 or It is executed based on winning of GRP22.
Here, in the lottery groups GRP1, GRP15, and GRP22, the winning probability is set to be constant regardless of the set value.

  As the lottery processing related to the instruction function, in addition to the above-described advantageous state transition lottery processing and continuation rate addition lottery, the number of initial set games and continuation rate determination processing shown in FIG. 13B and the next time shown in FIG. Although the number of set games and the continuation rate determination process are included, the main control device 31 must take charge of the lottery process related to all the instruction functions according to the rules relating to the gaming machine.

In addition, since a certain limit is imposed on the storage capacity of the main control device 31 in accordance with the gaming machine-related rules, it is desirable that the lottery processing related to the instruction function be as small as possible.
Therefore, in the slot machine 1 of the present embodiment, the winning probability and the distribution rate are set in common for the above-described advantageous state transition lottery process and the continuation rate extra lottery process regardless of the set values.
Thereby, compared with the case where these are not made a common setting, the capacity | capacitance concerning the lottery process concerning an instruction | indication function can be reduced.

However, with this alone, there is a problem that the pitching performance related to the instruction function becomes constant regardless of the set value.
Therefore, in the slot machine 1 of this embodiment, the winning probability in the advantageous state shift lottery process is set to 100% as shown in FIG. 13A, and the continuation rate is added as shown in FIG. 15B. The lottery group GRP22 that is also set as an opportunity for the game, that is, the RT6 in which the winning probability of the replay 6 role (watermelon RP) is relatively high is provided, and the transition to the RT6 is based on the set probability If you win a lottery group GRP2 with different BB2, that is, the BB2 role, and you win the RB2 role by winning the lottery group 25 with different winning probabilities according to the set value, that is, the RB2 role during the BB2 game Limited to. Since the probability of shifting to RT6 increases as the set value increases, it is possible to make the pitching performance related to the instruction function in accordance with the set value.
In addition, since the winning probability of the BB2 role is different depending on the set value, the ball performance related to the ball that is obtained during the BB2 game accompanying the winning of the BB2 role also depends on the set value. The difference in the corresponding ball-out performance can be made more remarkable.

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, the transition to RT6 where the winning probability of the replay 6 role (watermelon RP) is relatively high is that the BB2 role having a different winning probability according to the set value is won and the BB2 role winning In the following BB2 game, it was assumed that RB2 role with different winning probabilities according to the set value was won, but instead of this, the configuration of transitioning to RT6 through RT5 after completion of BB2 game, RT5 is omitted It is also possible to adopt a configuration in which the process is directly shifted to RT6.
Further, after the BB2 game is over, instead of the configuration in which the transition is made directly to RT6, the game state corresponding to RT6 of the present embodiment, that is, the normal state is shifted to the advantageous state via another gaming state (RT). It is also possible to adopt a configuration in which a transition is made to a gaming state (hereinafter referred to as a high probability state) in which the winning probability of at least one transition lottery trigger is relatively high among a plurality of types of transition lottery triggers for lottery. Is possible.
Also in this case, the winning probability of the transition lottery opportunity from the gaming state in which the winning probability of at least one transitional lottery trigger is relatively low (hereinafter referred to as the low probability state) among the plurality of types of transitional lottery triggers. As a transition route to a relatively high gaming state (hereinafter referred to as a high-probability state), a bonus combination with a different winning probability is won according to a set value, and a transition is made through a bonus game based on winning of the bonus combination. If a route exists, the probability of passing through the transition route also depends on the set value, so that the same effect as the slot machine 1 of the present embodiment can be obtained.
