In such a case, a setting is made such that seven prize balls are paid out per one prize ball.

First, in the player, the special winning opening 18 and the specific passing opening 19 for creating a condition for converting the large winning opening 21 and the small winning opening 23 into the second state advantageous to the player are concentrated. The target unit 20 disposed at the center of the game unit 14 is hit and fired. That is, since the specific winning means unit 20 is provided with one specific winning opening 18 and two specific passing openings 19, the hitting ball is moved to the specific winning opening 1
When the player wins No. 8, the first variable display device 15 starts variable display, and when the stop symbol stops in a preset mode, it becomes a "big hit", for example, for about 30 seconds or the ten count switch 64 turns the winning ball. The game is shifted to a special game in which the special winning opening 21 is opened up to 16 times at the maximum until the count of 10 is counted as one cycle. When the special switch 67 detects a ball during one cycle, the special game repeats the transition to the next cycle, and can be updated up to a maximum of 16 cycles. When the hit ball passes through the specific passage opening 19, the second variable display device 16 starts variable display,
When the stop symbol is in a preset mode, it becomes "hit" and the second variable winning device 24, which is the small winning opening 23, is opened for about 3 seconds, for example, and the ball is stored on the small opening / closing plate 38 and closed. Sometimes one ball is taken in and another ball falls from the ball path 105. Therefore, when the second variable prize device 24 is opened, one prize can be reliably won.
Cannot win more than one prize.

Also, when the special winning opening 21 or the small winning opening 23 is opened, if the player hits the specific winning means unit 20 and fires the game balls, the game balls concentrate on the center of the game unit 14 and the large game balls are concentrated. It flows into the winning opening 21 and the small winning opening 23. Therefore,
The player only has to aim at a fixed target and fire the target, and it is not necessary to change the target according to the progress of the game, and the game is easy to understand. In addition, the control means emits various sound effects from the speakers according to the progress of the game, and turns on or blinks various indicator lights to excite the game.

The small winning opening 23 can be opened at any time during the pachinko game based on the achievement of a predetermined condition. For example, the following manner can be set. The achievement of the predetermined condition is performed based on the storage of the start storage indicator lamp 89. When the special game is continued, that is, in the above-mentioned pachinko game, when the first variable display device 15 which is a special symbol display device displays a predetermined symbol and stops, the state becomes a "big hit" state, The special winning opening 21 can be opened 16 times. Therefore, the special game state is set when the small winning opening 23 can be opened regardless of whether the large winning opening 21 is opened or closed. While the special winning opening 21 is open, that is, while the special winning opening 21 is open in the special game state, the small winning opening 23 is set to be openable. During the interval when the special game is ongoing and the special winning opening 21 is opened 16 times, that is, during the opening of the special winning opening 21
Is set when the small winning opening 23 can be opened until the next opening is performed. The time when it is not in the special game state, that is, the time of the normal game state without the big hit state is set when the small winning opening 23 can be opened. When the special winning opening 21 is opened, the small winning opening 23 is simultaneously opened, and when the special winning opening 21 is closed, the small winning opening 23 is closed.
Also closes at the same time. That is, the big winning opening 21 and the small winning opening 23
And open and close at the same timing. If the closing time of the small winning opening 23 is not specified, the large winning opening 2
You may make it close simultaneously when 1 closes. Further, as described above, the timer may be closed when a predetermined time has elapsed.

In the above-mentioned pachinko game, the large winning opening 21 and the small winning opening 23 operate independently or in association with each other. For example, if both the large winning opening 21 and the small winning opening 23 are opened, a ball that could not win the large winning opening 21 can be guided to the small winning opening 23 to be able to win. Further, if the small winning opening 23 is opened at the same time when the large winning opening 21 is closed, it is possible to pick up a ball that failed to win the large winning opening 21 in timing. Furthermore, grand prize mouth 21
When a predetermined number of balls have been won, by closing the special winning opening 21 and opening the small winning opening 23, the winning of the special winning opening 21 is restricted, but the winning in the small winning opening 23 is permitted. The setting can be made so that the management of the payout becomes easy. On the other hand, the special switch 6 of the special winning opening 21
The small winning opening 23 can be opened when the 7 is activated. That is, according to the pachinko machine of the present invention, various games can be set, and a variety of interesting games can be provided. For example, when the special game using the first variable display device 15 is completed, the hit probability of the second variable winning device 16 is changed from “1/10” to “1/1”.
May be changed to a game in which the probability fluctuation state is set until the end of the next special game.

The above description of the game relates to a so-called first-class pachinko machine in which the special symbol display device shifts to the special game and opens the variable prize device when the stop symbol is displayed in a predetermined mode. However, the present invention is advantageous to the player from the first state, which is disadvantageous to the player, by the fact that the hit ball flows into the starting port when specific conditions such as the hitting of the hit ball at the special winning opening are established and the right state is established. The variable winning device that can be converted to the second state can also be applied to a so-called third-type pachinko machine that converts to the second state.

For example, the special winning opening 21 is changed to a variable winning device,
The small winning opening 23 is set as a starting opening, and when a ball is hit in the starting opening, the large winning opening 21 which is a variable winning device is opened for about 10 seconds or until the 10 count switch 64 detects 10 balls. One cycle is set, and the large winning opening 21 can be repeated up to 16 cycles based on the fact that the hit ball wins the small winning opening 23 which is the starting opening again.

At this time, according to the present invention, the special winning opening 21
The small winning opening 23 is located below the small winning prize opening 23, and a predetermined number or more of the hit balls do not enter the small winning prize opening 23. In other words, the small winning prize opening 23 serving as the starting opening can be surely made one prize. Thus, the cycle can be reliably updated. In addition, if the large winning opening 21 and the small winning opening 23 are closed together, the maximum number of winning balls allowed in the large winning opening 21 can be maximized, and then the starting opening can be won.
Effective use of rights.

On the other hand, the small winning opening 23 can be set as a specific winning opening that generates a right to open the large winning opening 21 which is a variable winning device. That is, in the present invention, the number of hit balls that the small winning opening 23 can take in at one time can be determined. Since this number may be one, in this case, it is set to one. As a result, two or more wins will not be made at the same time in the specified winning opening, and the right will be generated and the right will be extinguished almost simultaneously, the right will not be exercised, and the player will feel dissatisfied. There is no. The small winning opening 23 which is a specific winning opening may be opened as a big hit when the symbol stopped and displayed by the special symbol display device is in a predetermined mode.

Although the present invention has been described with reference to the embodiment shown in the drawings, the present invention is not limited to the above-described embodiment, and can be appropriately implemented unless the structure described in the claims is changed. For example, the effective area may be configured in any way, and the guide rib may be in any shape. In the embodiment, one ball is taken in, but two or three balls may be taken.

In addition, since a region in which a prize can be won can be formed beyond the actual width of the small prize opening, a sense of expectation of a prize is increased and the prize winning device can be downsized. Moreover, the small winning opening can reliably capture one ball, in other words, cannot capture one or more balls, so that the player can have a sense of expectation of winning,
When it comes to a game store, it does not mean that the prize will increase as much as it looks, and it is possible to provide a pachinko machine with easy payout management that balances the profit between the player and the game store.
