FIG. 3 is a block diagram illustrating a control system. Reference numeral 26 denotes a game control means, which comprises a CPU, a ROM, a RAM, and the like, and has a function of mainly controlling a game operation on the game board 4 side in accordance with a game control program stored in the ROM. The game control means 26 is a first symbol change display means.
A first control system 27 that performs control related to the control unit 21, a second control system 28 that performs control related to the second symbol change display unit 22, and various control systems 29 that perform other various controls are configured. I have.

The second control system 28 includes a hit determination processing means 30, a second symbol variation control means 31, and an opening / closing control means 32. The hit determination processing means 30 determines whether or not the stop symbol of the second symbol change display means 22 displays a hit symbol by random number processing on condition that the second symbol starting means 16 detects a game ball. Then, when the second symbol starting means 16 detects a game ball, a random number value of a hit random number for hit / miss determination repeatedly generated in a predetermined cycle is extracted, and when it is a hit determination value, it is determined that the hit is a hit. It has become.

The second symbol variation control means 31 has a function of varying the second symbol of the second symbol variation display means 22 for a predetermined time on condition that the second symbol starting means 16 detects a game ball, and a hit judging process. The second condition is that the means 30 determine a hit.
It has a function of controlling the second symbol of the symbol variation display means 22 to stop at a predetermined winning symbol (for example, an odd symbol). The opening / closing control means 32 keeps the opening / closing claw 23 of the first symbol starting means 14 for a predetermined time (for example, about 0.5 seconds) on condition that the stopped symbol of the second symbol variation display means 22 hits and displays the symbol.
It is designed to open.

The first control system 27 includes a jackpot determination processing means (a special random number determination processing means) 33 and a first symbol variation control means 34.
And a special prize providing means 35 and a jackpot determination value switching means (special prize determination value switching means) 36.

The big hit determination processing means 33 is operated by random number processing on condition that the first symbol starting means 14 detects a game ball, and whether the stop symbol of the first symbol change display means 21 displays a big hit symbol. The game machine has a lottery game function of randomly determining whether or not it is a random number process, and includes a jackpot random number counter (special prize lottery random number counter) 37 and a jackpot determining means (special prize determining means).

When the jackpot probability (prize probability) is, for example, 1/401, the jackpot random number counter 37 repeats a counting operation for sequentially counting from an initial value each time the game control program ends, thereby obtaining a jackpot determination value (prize). The jackpot random numbers (special lottery random numbers) from 0 to 400 including the judgment value are sequentially generated in a constant cycle. The jackpot determining means 38 is a counter for the jackpot random number at that time, provided that the first symbol starting means 14 detects a game ball.
37 random numbers are extracted, and when the random number matches a jackpot determination value variably set in advance, it is determined that a jackpot is determined.

The first symbol variation control means 34 has a function of varying the first symbol of the first symbol variation display means 21 for a predetermined time on condition that the first symbol starting means 14 detects a game ball, and a jackpot determination process. The means 33 displays the big hit symbol on the stop symbol of the first symbol change display means 21 based on the result of the lottery game of extracting the big hit determination value from the random number value of the big hit random number, and (1) The function of extracting and determining the jackpot symbol to be displayed on the stop symbol of the symbol variation display means 21 and the jackpot determination processing means 33 extracting the outlier random number value other than the jackpot determination value among the random numbers of the jackpot random number. It has a function of displaying a deviated symbol as a stop symbol of the first symbol change display means 21 on the condition.

It should be noted that the first symbol variation control means 34 determines a predetermined number (for example, 4) when the first symbol activation means 14 detects a winning of a game ball during the variation operation of the first symbol variation display means 21.
), And the first prize within the range of the stored number.
The fluctuation / stop is continued after the fluctuation of the symbol fluctuation display means 21 is completed.

The special prize providing means 35 is a first symbol change display means.
This is for generating a profit state advantageous to the player on condition that the 21 stop symbols display a big hit symbol such as "7 / 7.7". The special prize providing means 35 has a control function of opening the open / close plate 24 of the variable winning means 15 on condition that a big hit in which the first symbol change display means 21 stops at the big hit symbol, and a predetermined time from the opening of the open / close plate 24. Has elapsed, or when a predetermined number of game balls have been won in the variable winning means 15, the opening / closing plate 24 is closed, and the game balls that have been won during opening are in the specific area 25.
Has a function of controlling the opening and closing operation to be continued up to a maximum of a predetermined number of times on condition that the vehicle passes through.

The jackpot determination value switching means 36 is for switching and changing the jackpot determination value in the jackpot random number by random number processing when a preset predetermined condition is satisfied. The jackpot determination value switching means 36 includes a determination value switching counter 39 for counting switching random numbers equal to or less than the number of the random numbers 1 to 401 of the jackpot random number. Upon termination, the switching random number value counted by the determination value switching counter 39 is updated to the jackpot determination value of the jackpot determination means 38. It should be noted that this update can also be triggered by acquiring the jackpot determination value.

As shown in FIG. 4, the judgment value switching counter 39 utilizes the fact that the game control means 26 repeats the program processing in accordance with the game control program every one interruption time T, and uses one interruption time T. The count value is updated within the remaining time t from the end of the program processing in the above to the start of the next program processing.

Next, the operation of the above-mentioned ball game machine will be described. When the firing handle 10 of the firing means 9 is operated with the game ball on the upper plate 7, the game ball on the upper plate 7 is
The game balls are supplied one by one to the firing unit in conjunction with the firing operation of No. 9, and the game balls are hit with a hitting hammer and sequentially fired along the guide rails 11 to the game board 4 side.

While a game ball fired on the upper side of the game board 4 falls along the board surface of the game board 4, the game ball is
When passing through the symbol starting means 16, the second symbol variation control means 31
Works to change the second symbol of the second symbol change display means 22 for a predetermined time. On the other hand, when the second symbol starting means 16 detects a game ball, the hit determination processing means 30 extracts a random value of the hit random number and makes a hit determination based on whether or not the hit value is a hit value. Stopping of the two symbol variation display means 22 is stopped so that the predetermined symbol is displayed.

When the stop symbol of the second symbol change display means 22 becomes a hit symbol, the open / close control means 32 operates to open the pair of open / close claws 23 of the first symbol start means 14. For this reason, a game ball can be easily won in the first symbol starting means 14, and the first symbol of the first symbol change display means 21 can be easily changed accordingly.

When the opening / closing claw 23 of the first symbol starting means 14 is opened and the game ball wins, the first symbol variation control means 34 operates and the first symbol of the first symbol variation display means 21 similarly varies for a predetermined time. I do. On the other hand, when a game ball is won in the first symbol starting means 14, the jackpot determination processing means 33 performs a jackpot determination process, and determines whether or not to stop the first symbol at the big symbol after the first symbol variation display means 21 changes. Is determined.

That is, in the jackpot determination processing means 33, each time the program processing of the game control program of the entire game control means 26 is completed once, the jackpot random number counter 37 counts. When the first symbol starting means 14 detects a winning of a game ball, the jackpot determining means 38 extracts a random value of the jackpot random number at that time. If the random number of the jackpot random number is, for example, the jackpot determination value 75, the jackpot determination unit 38 determines that the jackpot is a big hit, and the first symbol variation control unit 34 operates to change each symbol after the first symbol variation display unit 21 changes. Stops at a predetermined jackpot symbol such as “7.7.7”.

When the stop symbol of the first symbol variation display means 21 displays a big hit symbol, the special prize providing means 35 operates to open and close the open / close plate.
The variable winning means 15 is converted and driven to a first state in which the opening 24 is opened to the front side. For this reason, most of the game balls falling from the upper side of the game board 4 easily enter the variable winning means 15 via the opening / closing plate 24. Then, when the game ball wins the variable winning means 15,
The payout means is operated by the payout control means, and 15 prize balls are paid out for each winning ball. Therefore, once a big hit occurs on the first symbol change display means 21 side, a great profit is returned to the player.

The variable winning means 15 closes the open / close plate 24 when ten game balls win or when a predetermined time has elapsed. Then, if the winning game ball passes through the specific area 25 while the opening and closing plate 24 is open, the variable winning means 15 opens again,
The opening and closing operation is repeated up to 16 times.

In the game control means 26, as shown in FIG.
In accordance with the game control program stored in the OM, the program processing within one interruption time T is repeatedly performed at a constant cycle. Then, in the big hit determination processing means 33, the big hit random number counter 37 sequentially counts in the ascending direction for each program processing, and repeats the counting operation from 1 to 401, and the detection signal from the first symbol starting means 14 Is read, and it is determined whether or not the random number value at that time is the big hit determination value 75 to perform the big hit determination processing.

In the jackpot determination value switching means 36, the determination value switching counter 39 sequentially counts the remaining time t of one interrupt time T in the ascending order each time the program processing is completed. Repeat.
When the special prize is awarded by the special prize awarding means 35, the jackpot determination value switching means 36 extracts the switching random number value of the determination value switching counter 39 at the time when the special prize is awarded, and the switching random number value Then, the jackpot determination value of the jackpot determination means 38 is updated. For example, if the switching random value is 350,
Since the jackpot determination value of the jackpot determination unit 38 is updated to the random number value, the jackpot determination unit 38 performs the determination operation with the jackpot determination value of 350.

Accordingly, if a special prize is provided by the special prize providing means 35, each time the special prize is provided, the big hit determination value switching means 36 causes the random value of the determination value switching counter 39 to be changed to the big hit by the big hit determination means 38. Since the judgment value is switched, the big hit judgment value of the big hit judgment means 38 can be changed every time the special prize is given by the special prize giving means 35. For this reason, the jackpot determination value of the jackpot determination means 38 changes irregularly each time a special prize is awarded, and the periodicity of the jackpot determination value disappears. It is impossible to grasp the jackpot and improperly hit the jackpot.

The decision value switching counter 39 of the jackpot decision value switching means 36 updates the remaining time t during one interrupt time T of the game control program following the program processing, and performs the program processing. Since the processing time changes every time, the remaining time t changes,
Since the number of times the random number value is updated becomes indefinite, the switching random number value can be changed irregularly.

FIG. 5 illustrates a second embodiment of the present invention,
The jackpot determination value switching means 36 is operated in accordance with a specific out-of-lot lottery result selected by the lottery game function to switch the jackpot determination value of the jackpot determination means 38.

That is, the jackpot determination value switching means 36 comprises specific outlier random number value extracting means 40 for extracting a predetermined outlier random number value among the jackpot random numbers of the jackpot random number counter 37. When the numerical value extracting means 40 extracts a specific outlier random number value, the random number value of the judgment value switching counter 39 is updated as the big hit judgment value of the big hit judging means 38.

Therefore, also in this case, the jackpot determining means
38 jackpot judgment values can be changed irregularly. Further, if a large number of random numbers are set in the out-of-specific random number extracting means 40 as out-of-specific random values, the jackpot determination value changes every time those random numbers are extracted, so that the jackpot determination value can be changed frequently.

In the embodiments, the following inventions are described. First, a plurality of types of prize means 14, 15, 17 to 19 are provided in the game area 12 of the game board 4, and among the plurality of types of prize means 14, 15, 17 to 19, a specific prize means 14 is provided.

In a ball game machine having a special prize providing function for providing an advantageous state, a special prize determination value switching means 36 for switching a special prize determination value among the random prize random numbers for the lottery game according to a preset condition is provided. Things.

Second, the symbol starting means 14 and the symbol variation display means 21 in which one or more symbols fluctuate for a predetermined time and stop.
Special prize determination processing means 33 for determining whether or not the stop symbol of the symbol change display means 21 displays a special prize symbol by random number processing on condition that the symbol starting means 14 detects a game ball.
And that the symbol of the symbol variation display means 21 is varied for a predetermined time on condition that the symbol starting means 14 detects a game ball, and the special prize determination processing means 33 extracts a special prize determination value of a special prize lottery random number. A symbol fluctuation control means 34 for displaying a special prize symbol on the symbol fluctuation display means 21 as a condition, and a special prize providing means 35 for giving a state advantageous to a player on condition that the symbol fluctuation display means 21 displays a special prize symbol. And a special prize determination value switching means 36 for switching a special prize determination value according to a preset condition.

Thirdly, in the first or second aspect of the present invention, the special prize determination value switching means 36 is operated every time a special prize is provided by the special prize providing function to switch the special prize determination value.

According to a fourth aspect of the present invention, in the first or the second aspect, the special prize judgment value switching means 36 is operated so as to switch the special prize judgment value by operating according to a specific out-of-lot result selected by the lottery game. It was done.

The random number value of the judgment value switching counter 39 when the preset condition is satisfied is set as the special prize judgment value.

The embodiments of the present invention have been described above.
The present invention is not limited to this. For example, the number of jackpot random numbers and the number of switching random numbers in each embodiment are merely examples, and are not limited to the numbers. It is also possible to set a plurality of jackpot determination values in the jackpot random numbers.

In the first embodiment, each time a special prize is awarded, at the end thereof, and in the second embodiment, each time an out-of-specific random number value is extracted, the jackpot determination value switching means 36 switches the jackpot determination value. However, both may be used in combination. It is also possible to switch according to conditions other than these. Therefore, the switching condition is
It is sufficient if certain conditions are set in advance.
