Abstract

<P>PROBLEM TO BE SOLVED: To change an updating cycle of a random number for big winning judgement in accordance with a game state. <P>SOLUTION: A first interrupt counter is increased by one (S11) and the game state is judged. Advance to S16 is performed at a time shortening game (S12:NO), the advance to S16 is performed when the first interrupt counter is ≥2 (S14:YES) at affirmative judgement in S12 and a probability variable game (S13:NO), and the advance to S16 is performed when the first interrupt counter is ≥3 (S15:YES) at a normal game (NO in both S12 and S13). In S16, the value of a big winning random number counter is increased by one and the first interrupt counter is cleared (S17). While the updating cycle of the big winning random number counter can be changed in accordance with the game state, adverse effects due to the change of the cycle are not produced because the cycle of executing a main routine is not changed. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention belongs to the technical field of ball game machines.

  A so-called jackpot game that has a jackpot game is provided with a jackpot determination random number counter (a jackpot random number counter) whose value is periodically updated. The value of the random number counter is read, the read value is compared with a predetermined hit value, and if it matches, it is determined that the hit is not matched (determination means), and the result of the determination is confirmed after the variable display It is displayed according to the displayed symbol (display means), and it is an essential condition that the judgment is a win (as a prerequisite that the symbol indicating the win is a definite display as a phenomenon recognized by the player) It is configured to execute a jackpot game. The collation with the winning value (determination as to whether or not it is a big hit) is usually performed after waiting for the symbol indicating the determination result made in advance to be finalized and displayed.

  Conventionally, the jackpot random number counter is configured to update (+1) a value in a random value updating process in a main routine executed by a user reset signal (user interrupt) generated every predetermined time. That is, each time the main routine is executed once, the value of the jackpot random number counter is updated (+1) (the update period of the jackpot random number counter is the execution period of the main routine).

Also, the configuration is such that the initial value of the next count cycle is changed when all the possible values of the counter have passed (for example, when a counter of 0 to 312 is used and 313 random number update processes are performed) Is adopted so that the current value of the counter is not judged externally (for example, “hanging board”).
JP 2000-233059 A

  In the conventional ball game machine, the initial value of the jackpot random number counter is changed as described above. However, the update cycle (the cycle in which the count value is incremented by 1, that is, all the values that the counter can take) The time required for this did not change.

  For example, it is possible to change the update cycle by changing the user interrupt generation cycle according to the gaming state, but because the adverse effect of changing the user interrupt generation cycle is great, it is adopted by ball game machines Generally, all of the possible gaming states (the normal gaming state, the probability variation gaming state, or the short-time gaming state) are made uniform, and no change according to the gaming state has been made.

The bullet ball game machine according to claim 1 reads the value of the jackpot random number counter (big hit random number counter) for jackpot determination whose value is periodically updated and the value of the jackpot random number counter when the lottery condition is satisfied. A determination means for comparing a value with a predetermined hit value to determine a hit and a display means for displaying a determination result of the determination means by a symbol that is fixedly displayed after a variable display; Is a ball game machine that is configured to perform the next collation after the symbol indicating the determination result is confirmed and displayed by the display means.
Update period changing means for changing the update period of the jackpot random number counter according to the gaming state,
The minimum variation time of the variation display by the display unit is set so that the determination unit cannot perform the collation a plurality of times within the time required for passing through all possible values of the jackpot random number counter. And

  Since the update period changing means for changing the update period of the jackpot random number counter according to the gaming state is provided, the update period of the jackpot random number counter can be changed according to the gaming state.

  In the conventional ball game machine, the jackpot random number counter is updated (+1) every time the main routine (random number value update process) is executed once. However, every time the random number value update process is executed once according to the gaming state. The update cycle of the big hit random number counter can be changed by updating (+1) or updating (+1) every time it is executed three times.

  Moreover, the cycle in which the main routine is executed (user interrupt generation cycle) is not changed, and this cycle can be made common in each gaming state such as the normal gaming state, the probability variation gaming state, and the short-time gaming state. There is no adverse effect caused by changing the value (control suitable for each gaming state is possible).

  In addition, the minimum variation time of the variation display by the display unit is set so that the determination unit cannot perform a plurality of collations within the time required for passing through all the values that the jackpot random number counter can take.

  For example, in gaming state A, the random number value update process is incremented by +1 each time, in gaming state B, it is incremented by 1 every time it is performed twice, and in gaming state C, it is incremented by 1 every time it is performed three times. The maximum value of the time required to pass through all possible values (one period of the jackpot random number counter) is the gaming state C (+1 for every three executions). The minimum variation time of the variation display by the display means is set so that even in this gaming state C, the determination means cannot perform multiple verifications within the time required for passing through all the values that the jackpot random number counter can take. Therefore, in any of the game states A, B, and C, collation with the winning value by the judging means (judging judgment) cannot be performed a plurality of times within one period of the big hit random number counter.

Thereby, it is possible to prevent the fluctuation time from being simply shortened and the number of collations (determination) per unit time from being increased.
The ball game machine according to claim 2
A jackpot determination random number counter whose value is periodically updated (hereinafter referred to as “big hit random number counter”), and when the lottery condition is satisfied, the value of the jackpot random number counter is read and the read value is predetermined. A determining means for comparing the winning value with the winning value; and a display means for displaying the determination result of the determining means by a symbol that is fixedly displayed after the variable display, wherein the determining means indicates the determination result. In a ball game machine that is configured to perform the next verification after the symbol is confirmed and displayed by the display means,
Update period changing means for changing the update period of the jackpot random number counter according to the gaming state;
The minimum fluctuation time of the fluctuation display by the display means is set to the value of the jackpot random number counter so that the determination means cannot perform the collation multiple times within the time required for passing through all the values that the jackpot random number counter can take. And a minimum variation time setting means for setting every update cycle.

Since the update cycle changing means for changing the update cycle of the jackpot random number counter according to the gaming state is provided, the update cycle of the jackpot random number counter can be changed as in the first aspect.
Assuming that the update period of the jackpot random number counter in the gaming states A, B, and C is set in the same manner as in the above example, the time required for passing through all possible values of the jackpot random number counter (one period of the jackpot random number counter) is Since the game state C> the game state B> the game state A, the minimum variation time of the variable display by the display unit is prevented so that the determination unit cannot perform multiple verifications (determination) within one cycle of the jackpot random number counter. Is set for each update period of the big hit random number counter, it is possible to prevent the fluctuation time from being simply shortened and the number of collation (determination) per unit time from being increased.

  In addition, since the minimum variation time is individually set according to the gaming states A, B, and C, the setting is more preferable.

Next, embodiments of the present invention will be described based on examples of the present invention. The present invention is not limited to the following examples and the like, and it goes without saying that the present invention can be implemented in various ways without departing from the gist of the present invention.

The display screen 37a of the character display device 37 corresponds to the window portion 34a of the center case 34, and the display screen 37a can be seen through the window portion 34a. In the character display device 37 (display screen 37a), symbols may be displayed in synchronism with the fluctuation display and final display of the special symbol display device 35, but this is only a display for presentation.

  On the left and right sides of the center case 34, passing gates are installed as normal symbol starting ports 38, and tulip-type variable winning devices are installed as special symbol starting ports 39 below the center case 34. The special symbol starting port 39 is provided with a normal symbol display device 40 of 7 segments LED and a universal figure holding number display device 41 composed of four LEDs.

  When the game ball passes through the normal symbol start port 38, a normal symbol lottery is performed, and the result is indicated by a normal symbol that is fixedly displayed by the normal symbol display device 40 after the variable display. When the normal symbol lottery is won (when the normal symbol corresponding to the normal symbol display device 40 is confirmed and displayed), the special symbol start port 39 is opened for a specified time (which changes depending on the gaming state). However, if a prescribed number (for example, three) of winnings occurs, the opening is completed even before the prescribed time is reached.

Under the special symbol start opening 39, an attacker-type big winning opening 42 is arranged, and two general winning openings 43 are arranged on the left and right sides (obliquely above) of the big winning opening 42, respectively.
As shown in FIG. 3, the control system of the pachinko machine 10 is configured around a main control board 45. Although details will be described later, the main control board 45 functions as a determination unit, an update cycle changing unit, and a minimum variation time setting unit.

  The main control board 45 has a touch switch that detects that the player is touching (operating) the launch handle 25, a ball break switch that detects that the ball tank is empty, and the lower plate 23 is full. A full tank switch for detecting that it has become, a general winning port switch 43a for detecting a winning ball to each general winning port 43, a count switch 42a for counting the winning balls to the big winning port 42, a normal symbol start Detection signals such as a mouth 38 (built-in passing ball detection switch) and a special symbol start port 39 (built-in winning ball detection switch) are input.

  Although not shown in detail, the main control board 45, the prize ball control board 46, the launch control board 47, the effect control board 48, the lamp control board 49, and the sound control board 50 are all CPU, ROM, RAM, An input port, an output port, etc. are provided.

Next, the operation of the pachinko machine 10 will be described.
FIG. 4 is a flowchart of a main routine executed by the main control board 45. The main control board 45 is a jackpot determination random number counter (big hit random number counter), a big hit symbol determination random number counter (big hit symbol counter), a reach determination random number counter, a variation pattern determination random number counter, a missed pattern random number counter, Various random number update processing (S1) for updating values such as the initial value random number counter is performed.

  Each counter is incremented by 1, and if it reaches the upper limit value at that time, it is set to 0, thereby repeating the 0 to upper limit value (different for each counter). Details of the update of the jackpot random number counter will be described later (see FIG. 5), but the other counters are incremented by one each time various random number update processes (S1) are executed.

  In the next various input processes (S2), the detection signals of the above-described switches are input, and depending on the type of input (for example, the ball detection signals of the normal symbol start port 38 and the special symbol start port 39, etc.) Reading or storing (holding storage) the value of the random number counter to be performed.

  In the subsequent data creation process (S3), the above-described command generation, ordinary actor solenoid 39b, special symbol display device 35, ordinary symbol display device 40, special figure hold number display device 36, general figure hold number display device 41, etc. Data creation for controlling the operation is performed.

  The jackpot determination and the normal symbol lottery which are the premise of such data creation are also performed as a subroutine of the data creation processing (S3). Although these are performed by a known method, the outline of jackpot determination that is related to the present invention will be described.

  First, in various input processes (S2), when the ball detection signal of the special symbol start port 39 is input (satisfaction of the lottery condition), the number of special symbol reservation memories reaches the upper limit (four in this example). Unless otherwise specified, the value of the jackpot random number counter, jackpot symbol counter, reach determination random number counter, fluctuation pattern determination random number counter, and out symbol random number counter (the jackpot determination random number, jackpot symbol determination random number, reach determination random number, fluctuation Read pattern determination random numbers, out-of-design random numbers) and store them as special symbol hold memory.

  In the data creation process (S3), if the jackpot game is not being executed and the special symbol display device 35 is not in a variable display, the oldest one of the special symbol hold memories is temporarily stored for jackpot determination. Then, the second and lower storage positions are shifted one stage each. In addition, when there is no special symbol hold memory, this processing is not performed as well as the following processing.

  Subsequently, it is determined whether or not the jackpot determination random number of the data transferred to the temporary storage for jackpot determination matches one of the hit values recorded in the jackpot determination table, that is, whether or not the hit is determined (determination means). Note that the jackpot determination table has a normal use (low probability) and a probable change (high probability), and is selected and used according to the gaming state at that time (whether or not it is a probable changing gaming state).

  If this determination is successful, the jackpot symbol is selected based on the jackpot symbol determining random number, and the hit variation pattern (variation time) is selected based on the variation pattern determining random number. If it is off, select the off symbol based on the random symbol for the out symbol (however, if the reach determination random number is reach, replace it with a reach out symbol that is prepared separately), and change fluctuation based on the random number for determining the fluctuation pattern. Select the pattern (variation time). Then, a command (variation start command) including the jackpot symbol or the off symbol determined in this way and the variation pattern (variation time) is generated.

  In each of the following output processes (S4), the output of the command generated in S3, the normal accessory solenoid 39b, the special symbol display device 35, the normal symbol display device 40, the special figure hold number display device 36, the universal figure hold number display device The output for controlling the operation of 41 etc. is performed.

  As the control of the special symbol display device 35 by each output process (S4), the output operation for starting the change of the special symbol and confirming the display is performed. That is, the special symbol display device 35 is started to display the variation of the special symbol by the variation start instruction signal, and the special symbol indicating the determination result in the processing as the above-described determining means by the symbol determination instruction (7 in case of winning, missed) In case of, the other one-digit number) is confirmed and displayed.

  A variation start command is sent together with a variation start instruction signal. Upon receiving this command, the effect control board 48 controls the LCD panel unit 51 according to the command, thereby producing an effect display such as a pseudo symbol variation display or a character animation display. And so on. This effect display ends when the time specified by the variation pattern has passed and the pseudo symbol is confirmed and displayed. The pseudo symbol that is confirmed and displayed is a jackpot symbol or an off symbol designated by the change start command.

  Since the control of the special symbol display device 35 by the main control board 45, the transmission of the change start command, and the control of the LCD panel unit 51 by the effect control board 48 receiving it are performed as described above, the special symbol and the pseudo symbol are substantially the same. At the same time, the variable display starts and the display is confirmed at substantially the same time. The symbol indicating the result of the jackpot determination is a special symbol of the special symbol display device 35. However, since the pseudo symbol also corresponds to the result of the jackpot determination, the player can recognize the hit / success.

  When the result of the jackpot determination is a win and the special symbol indicating the hit is confirmed and displayed on the special symbol display device 35, the jackpot game is started. In the jackpot game, the grand prize winning opening 42 is opened up to the upper limit number of times (for example, 15 rounds), but the operation thereof is the same as that of the special game in the well-known first type pachinko machine, so the description is omitted.

  In the out symbol random number update processing (S5) following each output processing (S4), the value of the out symbol random number counter is updated, and in the next initial value random number update processing (S6), the value of the initial value random number counter is updated. . Outlier symbol random number update processing (S5) and initial value random number update processing (S6) are repeated until there is an internal INT (as long as S7 is NO).

The process of S7 is a process of confirming the presence or absence of an internal INT flag that is set every time the time measured by the timer built in the CPU of the main control board 45 reaches a predetermined time (4 ms in this example).
If a positive determination is made in S7, the process returns to S1 and the above-described processing is repeated. The internal INT flag is cleared with the start of S1, and the measurement of 4 ms by the timer is also reset with the start of S1, so the main routine is executed at a cycle of 4 ms.

The jackpot determination random number update process (update of the jackpot random number counter), which is a subroutine of various random number update processes (S1), is performed as shown in FIG.
In this process, first, the first interrupt counter is incremented by 1 (S11).

Next, it is determined whether the time reduction flag is 0 (S12) or whether the probability variation flag is 0 (S13).
The short time flag is a flag (set to 1 during a short time game) indicating that the special symbol variation time is set to be shorter than the normal game state. The probability variation flag is a flag (set to 1 during probability variation game) that indicates a probability variation gaming state in which a jackpot determination table for probability variation is used in the jackpot determination by the determination means. That is, if a negative determination is made in S12, it is a short-time gaming state, if a negative determination is made in S13, it is a probable gaming state, and if both are positive in S12 and S13, it is a normal gaming state. It becomes a game state judgment means for this.

  If a negative determination (short-time game) is made in S12, the process jumps from S13 to S15 and proceeds to S16. If the negative determination is made in S12 (negative change game), the first interrupt counter is 2 or more (S14: YES). If so, the process proceeds to S16, and if both S12 and S13 are affirmative (normal game), if the first interrupt counter is 3 or more (S15: YES), the process proceeds to S16. If a negative determination is made in S15, the process returns.

In S16, the value of the jackpot random number counter is incremented by 1, and then the first interrupt counter is cleared (S17).
If one cycle of the jackpot random number counter is completed (S18: YES), the initial random number value (see S1 and S6 in FIG. 4) is set as the value of the jackpot random number counter (S19).

  By S16, S18, and S19, the value of the jackpot random number counter changes as shown in FIG. First, if the count starts from 0 and reaches the upper limit value (312 in this example), one cycle ends (S18: YES). If the initial value random number is 57 at this time, it becomes the value of the big hit random number counter (S19), and when it is incremented by S16 after that, it ends one cycle (S18: YES). Thereafter, the same operation is performed.

  By the way, the value of the jackpot random number counter is incremented by S16, but every time the jackpot determination random number update processing is executed, the first interrupt counter is incremented by 1 (S11), and the processing content is based on the value. Because of the change (S12 to S16), every time the big hit determination random number update process is executed once during the short-time game (that is, every time the main routine is executed once), the main routine is executed twice during the probability change game. Every time the main routine is executed three times during normal game, the value of the jackpot random number counter is incremented by one.

  Since the execution cycle of the main routine is 4 ms and the range of values that the jackpot random number counter can take is 0 to 312 (313), the time required for one cycle of the jackpot random number counter is as shown in FIG. It is 3756 ms in the normal gaming state, 2504 ms in the probability variation gaming state, and 1252 ms in the short-time gaming state.

  In this way, although the update cycle of the jackpot random number counter can be changed according to the gaming state, it does not change the cycle (user interrupt generation cycle) in which the main routine is executed, this cycle is the normal gaming state Since it is common to each gaming state such as a probability variation gaming state, a short-time gaming state, etc., no adverse effect is caused by changing this cycle (control suitable for each gaming state becomes possible).

  Then, as shown in FIG. 6B, the main control board 45 sets the minimum variation time of the special symbol to 4000 ms in the normal gaming state, 3000 ms in the probability variation gaming state, and 2000 ms in the short time gaming state (minimum variation time setting means). ). Thus, in the above-described selection of the variation pattern (variation time), a variation pattern having a variation time of 4000 ms or more in the normal gaming state, 3000 ms or more in the probability variation gaming state, and 2000 ms or more in the short-time gaming state is selected.

  As described above, the jackpot determination by the determination means is performed on the assumption that the special symbol display device 35 is not in a variable display, that is, the special symbol indicating the determination result is fixedly displayed by the special symbol display device 35 (display means). After that, the next determination is performed, and therefore, by setting the shortest variation time of the special symbol as shown in FIG. 6B, the determination unit determines the big hit by a plurality of times within one cycle of the big hit random number counter. Make it impossible. For this reason, it is possible to prevent the variation time from being simply shortened and increasing the number of jackpot determinations per unit time.

  However, since the minimum variation time is individually set according to the gaming state, the shortest variation time is shorter in the probability variation gaming state than in the normal gaming state, further shorter in the short-time gaming state, and as short as possible in each gaming state.

  By changing the minimum fluctuation time, the maximum number of fluctuations per unit time can be changed according to the gaming state, and the time until the next jackpot can be shortened at portions other than the change in jackpot probability.

  In addition, by setting the minimum fluctuation time to a time equivalent to one cycle of the jackpot random number, in a ball game machine that does not have a variable hold memory, the jackpot random number is within the same cycle regardless of the gaming state. Since there is no ball entering the starting port more than once during the update, the jackpot probability can be suitably used as a theoretical value, and even in a ball game machine equipped with variable hold memory, depending on the gaming state By changing the time required for one cycle of the jackpot random number and setting the minimum fluctuation time, there is support for winning at the starting point (shortening the fluctuation time of normal symbols and the operation of opening extension function of normal electric accessories) Even in this case, it is possible to perform suitable control.

  In general, in the probability variation gaming state and the short-time gaming state, the opening time of the variable winning device that becomes the special symbol starting port 39 is longer than that in the normal gaming state (this is also the case in this example), so The base is high. Therefore, as a gaming store, it is not nice that these gaming states last for a long time. However, according to the pachinko machine 10 of this example, since the shortest variation time can be shortened as much as possible in both the probability variation game state and the short-time game state, the number of jackpot determinations per unit time can be increased as much as possible, and as a result, these games The state can be terminated relatively early.

  On the other hand, since the base is set low in the normal gaming state, there is no need to extremely shorten the variation time. On the other hand, if it is too short, the winning at the special symbol starting port 39 cannot catch up with the end of the fluctuation of the special symbol, so there is a possibility that the time when the special symbol does not fluctuate frequently and gives a good impression to the player. Absent.

It should be noted that the minimum variation time may be set to a single value greater than or equal to the maximum time required for passing through all the values that the jackpot random number counter can take (in the above example, 3756 ms in the normal gaming state). Moreover, the structure which sets separately the minimum fluctuation | variation time separately in a normal game state and other than that (in the above example a probability change game state and a time-short game state) may be sufficient.
[Relationship between update rate of jackpot random number counter and probability fluctuation]
The relationship between the jackpot random number counter update cycle and the probability variation will be described with reference to a specific example shown in FIG. The “number of times” in the figure indicates the number of executions of the main routine (big hit determination random number update process). In addition, for the sake of simplicity, the jackpot symbol determination random number is assumed to repeat three values of 0, 1, and 2, where 0 is a normal symbol (no bonus after the jackpot), 1 is a probability variation symbol (after the jackpot game ends) 2 is a short-time symbol (the short-time game state is reached after the end of the big hit game).

  Assuming that the winning value is 3, in the normal gaming state, when the big hit (when the big hit determination random number is 3), the big hit symbol determination random number can take all of 0, 1, 2; There are three possibilities for the gaming state after the game is over.

  In the case of a promiscuous gaming state, when the jackpot is won (the jackpot determination random number is 3), the jackpot symbol determination random number can take only two values of 0, 1, and 2, depending on the initial value in S19 of FIG. The game state after the end of the jackpot game is biased to any two.

  In the case of the short-time gaming state, when the jackpot is reached (the jackpot determining random number is 3), the jackpot symbol determining random number is one of 0, 1, and 2, depending on the initial value in S19 of FIG. The gaming state after the end of the jackpot game is determined.

However, this is limited to one period of the jackpot random number counter. Considering multiple periods, 0 to 312 appear on average as the initial values in S19, so no particular problem occurs.
[Example of changing the update interval of random number counters other than the jackpot random number counter]
In the embodiment, an example in which the update cycle of the jackpot random number counter is changed is shown, but the update cycle of other random number counters can be changed in the same manner. Here, an example of changing the update cycle of the jackpot symbol determination random number will be described.

The jackpot symbol determination random number update process shown in FIG. 8 is executed as a subroutine of various random number update processes (S1), similarly to the jackpot determination random number update process of FIG.
In this process, first, the second interrupt counter is incremented by 1 (S21).

Next, it is determined whether the time reduction flag is 0 (S22) or whether the probability variation flag is 0 (S23). The processing contents and purpose of S22 and S23 are the same as S12 and S13 of FIG.
If the second interrupt counter is 3 or more in the negative determination (short time game) in S22 (S24: YES), the process proceeds to S26, and if the positive determination is in S22 and the negative determination is in S23 (probable change game), the second interrupt counter is 2 If it is above (S25: YES), the process proceeds to S26, and if both S22 and S23 are affirmative (normal game), the process immediately proceeds to S26.

In S26, the value of the jackpot symbol determination random number counter is incremented by 1, and then the second interrupt counter is cleared (S27).
If the jackpot symbol determination random number update process is performed in this way, the update cycle of the jackpot symbol determination random number can be changed according to the gaming state (normal gaming state, probability variation gaming state, short-time gaming state). When this is combined with the jackpot determination random number update processing of the embodiment (FIG. 5), the relationship between both random numbers is as shown in FIG. The setting of the winning value, the correspondence between the jackpot symbol determining random numbers 0, 1, 2 and the gaming state after the jackpot game are the same as in FIG.

In the normal gaming state, when the jackpot is large (when the jackpot determining random number is 3), the jackpot symbol determining random numbers can be 0, 1, and 2 (same as FIG. 7).
In the case of a promiscuous gaming state, when the jackpot is big (the jackpot determination random number is 3), the jackpot symbol determination random number can take only one value of 0, 1, and 2, depending on the initial value in S19 of FIG. Any one game state after the end of the jackpot game is determined.

  In the short-time gaming state, when the jackpot is reached (the jackpot determining random number is 3), the jackpot symbol determining random number is one of 0, 1, or 2, but the jackpot for three jackpot determining random numbers The difference is that it corresponds to one random number for design determination.

However, as in the case of FIG. 7, this is limited to one cycle of the jackpot random number counter, and considering multiple cycles, 0 to 312 appear on average as the initial values in S19, so no particular problem occurs. .
[Others]
Here, the example of changing the update cycle of the jackpot random number counter (FIG. 5) and the example of changing the update cycle of the jackpot symbol determination random number (FIG. 8) are shown, but the update cycle is similarly changed for other random number counters. it can.

  In addition, although the three game states of the normal game state, the probability variation game state, and the short-time game state are illustrated as the game state, it is not necessary to be limited to these. Or you may divide into two types like a normal gaming state and others.
