Abstract

PURPOSE:To increase the interest of a player until a finally determined pattern is displayed by judging a big prize when the sum or difference of figures displayed at individual digits of a combination display device becomes the preset value. CONSTITUTION:When the process executed by a CPU 10a is shifted to the digital display routine, whether a game ball enters either one of start ports 22-24 on a game board 2 or not is judged by a start port switch 22a. If 'Yes' is judged, the display data DDT as a pattern corresponding to the random number RN are read from a ROM 10b and outputted to digital indicators 21a-21c of a digital display device 21 via an external output circuit 10e. When the sum of displayed figures is displayed on a digital indicator 21d, whether this figure is the preset value corresponding to a small prize or a big prize is judged. The small prize and big prize occur when the sum of figures of three digits becomes the preset value even if the numbers and patterns displayed on the digital indicators 21a, 21b do not match.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a pachinko game machine,
More specifically, the present invention relates to a jackpot generating device that puts a variable winning device such as a jackpot into a state advantageous to a player with a certain probability.

0002

2. Description of the Related Art A combinational display circuit that generates a jackpot with a certain probability is usually composed of a three-digit display circuit.
Normally, when a game ball enters the starting hole, the symbols of each digit rotate at the same time, and the rotating symbols sequentially stop from the first to the third digit at predetermined time intervals, and the symbols are determined one after another. When all three digits are displayed with the same symbol, for example, "777", a jackpot state is generated in which a variable winning device such as a big winning opening is put in an advantageous state for the player.

0003

[Problem to be Solved by the Invention] However, in the above configuration, if the first digit symbol and the second digit symbol are not the same, the display of the third digit symbol stops rotating and the symbol is determined. There is no need to wait for the jackpot to occur. In other words, for the player, unless the first digit symbol is the same as the second digit symbol, the player cannot become more interested, and the time it takes for the third digit symbol to be determined is just wasted time. becomes. It is an object of the present invention to solve the above-mentioned problems and increase the player's interest until the final determined symbol is displayed.

0004

[Means for Solving the Problems] The pachinko game machine of the present invention includes a combination display device that displays at least two-digit symbols, and the display mode of the combination display device is a predetermined jackpot display mode. In a pachinko game machine that sometimes operates a variable prize winning device in a state advantageous to the player, a jackpot is determined when the sum or difference of the numbers displayed in each digit of the combination display device reaches a predetermined value. It is characterized in that it is determined by means.

[0005]

[Function] The pachinko game machine of the present invention having the above configuration,
Similar to conventional pachinko gaming machines, when a game ball enters the starting slot on the game board, the symbols of each digit on the combination display device start rotating and stop sequentially at predetermined time intervals to determine the displayed symbols one after another. , the jackpot determining means determines that the sum or difference of the numbers displayed in each digit is a predetermined value, and when a jackpot is determined, the variable winning device is operated in a state advantageous to the player. to work. At this time, it is undetermined that the sum or difference of the numbers displayed in each digit will be a predetermined value until the last number displayed. It works so that the jackpot is determined only after the number given is confirmed.

are connected by a gutter on the back side of the game board 2, and the entry of a game ball is detected by the starting port switch 22a.

[0010] The central accessory 20 has blades 25 and 2 provided on the left and right when a jackpot or small win, which will be described later, occurs.
6 is rotated by a predetermined angle to the left by a solenoid 25a and to the right by a solenoid 26a to take the game ball into the interior. In addition, inside the central accessory 20, there is a ten count switch 27 that counts the number of game balls that enter the central accessory, and about one-third of the game balls that enter the central accessory. A so-called V switch 2 for determining the continuation of the right is provided in a specific area through which the game ball passes with a probability of
8th class is also available. The digital display device 21 is
Three digital displays 21a to 21c each displaying a numerical pattern from 0 to 9, and the digital displays 21a to 21
c and a digital display 21d that displays the sum of the numbers respectively displayed.

The electronic control device 10, as shown in FIG.
Centering on the CPU 10a as a microcomputer, the CPU 10a, ROM 10b, RAM 10c,
The external input circuit 10d and the external output circuit 10e are connected to the bus 10.
They are configured as logic operation circuits interconnected by f. The external input circuit 10d of this electronic control device 10 includes the above-mentioned touch switch 7a, bulb cutout detection switch 11

The external output circuit 10e is connected to the digital display device 21, solenoids 25a and 25b, etc., which are also described above.

Next, the operation of this embodiment having the above configuration will be explained with reference to the flowcharts shown in FIGS. 5 to 8. The processing shown in FIGS. 5 to 8 executes the jackpot and small win processing that opens the left and right wings 25 and 26 of the central accessory 20, which serves as a big winning opening, among various processing performed by the electronic control device 10. It shows only the instructions that are executed periodically using methods such as hard interrupts.

FIG. 5 shows the processing executed by the CPU 10a.
When moving to the "digital display routine" shown in
The starting port 22~ on the game board 2 is activated by the starting port switch 22a.
It is determined whether or not a game ball has entered any of the 24 balls (step S100). Here, when an affirmative judgment is made that the ball has entered, display data D corresponding to the random number RN is displayed.
DT is read from the ROM 10b (step S11
0). As shown in FIG. 6, the random number RN is created as a random number from 0 to 999 by sequentially incrementing the previous random number RN by a hard interrupt every 2 ms (steps S111 to S113). Display data D as a pattern corresponds to this random number RN from 0 to 999.
DT is read from ROM 10b and external output circuit 10e
The digital display 21a of the digital display device 21 via
~21c (step S120). Therefore,
Depending on the timing when the game ball enters any of the starting ports 22 to 24, a random number RN from 0 to 999 is read and displayed on each digital display 21a to 21c.
Each of the numbers from 0 to 9 will be displayed, that is, a three-digit number will be displayed on the digital displays 21a to 21c. At this time, after the game ball enters one of the starting ports 22 to 24, the numbers as symbols displayed on each digital display 21a to 21c start rotating, and every predetermined period of time, the numbers displayed on the digital display 21a start rotating. It is the same as in the conventional art that the numeric symbols displayed at 21c are sequentially stopped and the displayed numeric symbols are finalized.

[0014] When the numerical symbols are displayed on each digital display 21a to 21c, each digital display 21a to 2
The sum of the numbers displayed on 1c is displayed on the digital display 21d (step S130).

[0015] When the sum of the three digit numbers is displayed on the digital display 21d, it is then determined whether the sum of the numbers is a predetermined value and a small hit or a jackpot (step S140).
~S150). In this embodiment, when the sum of the three digit numbers is 21, it is considered a small win, and when the number displayed on the digital display 21c is 7, it is considered a jackpot. As shown in Table 1 on the next page, there are 23 combinations of small wins and 5 combinations of jackpots, for a total of 2 combinations of small wins and jackpots.
There are 8 ways. Therefore, the probability of winning the jackpot is 5/100.
0, that is, 1/200.

[0016] If it is determined that it is a jackpot in the judgment process of steps S140 to S150, the jackpot flag Fg1
and sets the number of jackpots N to 16 (step S160), and when it is determined that it is a small hit, the process of setting the small hit flag Fg2 (step S170).
), the process exits to return. On the other hand, when a negative determination is made in step S100 or step S140, the process directly exits to return.

The jackpot processing is executed according to the "jackpot processing routine" shown in FIG. That is, jackpot flag Fg1
is set (step S200), the solenoids 25a and 26a of the central accessory 20 are turned on for 30 seconds or until the ten-count switch 27 counts 10 game balls, and the left and right blades 25 and 26 is opened (step S210). At this time, if the game ball enters the specific area and the V switch 28 is turned on (step S
220), and decrements the number of jackpots N (step S
230), if the decremented jackpot number N is not 0, the process exits to return (step S240). On the other hand, the number of jackpots N becomes 0, or the above step S220
If the V switch 28 is not turned on at step S
220), the jackpot flag Fg1 and the number of jackpots N are cleared to 0, and the process exits to return (step S250).

As shown in FIG. 8, the small win process is performed when the small win flag Fg2 is set (step S30).
0), turn on the solenoids 25a and 26a for 6 seconds or until the ten count switch 27 counts 10 game balls (step S310), and then turn on the small hit flag F.
Clear g2 to 0 and exit to return (step S3
20).

According to the present embodiment described in detail above, a jackpot and a small win occur when the sum of three digit numbers becomes 21 even if the numerical patterns displayed on the digital displays 21a and 21b do not match. Occur. In other words, even if the numerical symbols displayed on the digital displays 21a and 21b do not match, there is a possibility that a jackpot or small hit will occur, and the player will not be able to win until the numerical symbols displayed on the digital display 21c are determined. It has an excellent effect of providing interest. On the other hand, the number pattern displayed on the digital display 21a is "0"
, [1], or "2", there is no possibility of a jackpot or small hit occurring, and if a numerical symbol of "3" or more is displayed, there is a possibility of a jackpot or small hit. In other words, it also has the effect of providing the same interest as a so-called reach hit when the numerical patterns displayed on the digital displays 21a and 21b match.

[0020] In this embodiment, only the case where the number pattern displayed on the digital display 21c is "7" is considered a jackpot, but all cases where the sum of each digit is 21 may be considered a jackpot. Also, if the sum of each digit is 15, and the value obtained by subtracting the second and third digits from the first digit is zero, it may be considered a jackpot or a small win.

[0021]

[Effects of the Invention] According to the pachinko game machine of the present invention, even if the symbols displayed in the first and second digits do not match, there is a possibility that a jackpot or small win will occur; This has the excellent effect of keeping players interested until the numbers are determined, and has the excellent effect of further increasing the fun of the pachinko machine.
