Description

  The present invention relates to a ball game machine such as a pachinko game machine, and in particular, a ball that can increase the game performance in the big hit mode by increasing or decreasing the number of winning prize balls in the big hit mode according to the skill of the player. It relates to a ball game machine.

  A special electric accessory that opens or expands a specific prize opening and a special prize opening that is formed between a game board and a glass frame that covers the front of the game board. 2. Description of the Related Art A ball game machine equipped with an electric accessory is known. An ordinary electric accessory is opened when a winning of a game ball at a predetermined prize opening or a normal symbol lottery performed in response to the passing of a game ball at a predetermined gate is won, and a special electric accessory is a specific winning combination. When a special symbol lottery performed in accordance with the winning of a game ball to the mouth is won, the opening operation is performed. In particular, when the lottery result of the special symbol lottery is a big hit, the big hit mode appears after the special symbol change display, and during the big hit mode, a predetermined number of game balls (for example, nine) are won for the big winning opening. As an end condition for one round, the special electric accessory is released, and the opening operation is repeated a plurality of rounds (for example, 15 rounds) over a predetermined interval time. ).

  However, in this type of ball game machine, the number of winning balls in the big hit mode is almost constant regardless of the skill of the player. There was a problem of being. That is, most of the winning balls in the jackpot mode are performed in accordance with the winning of the game ball with respect to the big winning opening, and the special electric accessory is usually very easy to win the big winning opening when it is opened. Therefore, during the jackpot mode, there is almost no gaming element that requires the skill of the player.

Accordingly, a ball ball game machine has been proposed in which a plurality of ordinary electric actors are arranged in a distributed manner on the left and right sides of the game area, and the left and right ordinary electric actors are selectively opened in the big hit mode. For example, in the ball game machine described in Patent Document 1, in the jackpot mode, the left and right ordinary electric actors are selectively opened and the ordinary electric actors that are opened are notified in advance. It is possible to increase the gameability in the big hit mode by causing a difference between the number of winning balls when the left / right hitting operation is performed and the number of winning balls when not following the notice.
JP 2002-282484 A

  However, since the ball and ball game machine described in Patent Document 1 requires two or more ordinary electric accessories, there is a problem in that the manufacturing cost increases and the control becomes complicated as the number of parts increases. Exists. In addition, the number of ordinary electric accessories cannot be increased freely, and is restricted by the gaming machine rules. Therefore, it may conflict with the gaming machine rules and may not be implemented. By the way, according to the current game machine rules, the number of ordinary electric actors is one for a pachinko gaming machine with a special electric accessory, and a pachinko machine without a special electric accessory. In this case, since it is stipulated that the number does not exceed four, the ball game machine described in Patent Document 1 is substantially difficult to implement.

The present invention was created to solve these problems in view of the above situation, and a game ball formed and fired between a game board and a glass frame covering the front thereof is provided. The inflowing game area includes a plurality of winning holes, a large winning opening, a normal electric accessory that opens or expands a specific winning opening, and a special electric accessory that opens the large winning opening. When winning the normal symbol lottery performed when the above condition is satisfied, the normal electric accessory is released, and when winning the special symbol lottery performed when the second condition is satisfied, the big hit mode is set. During the jackpot mode, the special electric accessory is released for a plurality of rounds over a predetermined interval time, with a predetermined number of game balls winning through the big winning opening as a condition for ending one round. Repeated ball game In the machine, the special electric accessory includes a ball receiving piece for changing a posture between an opening posture for opening the grand prize winning opening and a closing posture for closing the big winning opening, and the ball receiving piece in the opening posture is a game area. The game ball that flows down is guided to the opened big prize opening, and the specific prize opening is provided on the downstream side of the ball receiving piece in the open posture, A plurality of interval times for the opening operation during the jackpot mode of the special electric accessory are set, and the interval times are selected based on a predetermined condition. In this way, the number of winning prize balls in the big hit mode can be increased / decreased without increasing the number of ordinary electric accessories, and the gameability in the big hit mode can be improved. In other words, if a short interval time is selected, even if the ordinary electric accessory is released, many game balls will win the big prize opening on the upstream side. Although the increase in the number of prize balls is small, if a long interval time is selected, the chances for a game ball to win a specific winning opening that is opened or expanded by the ordinary electric accessory increases. As a result, the number of winning award balls resulting from the increase in the number of winning award balls in the jackpot mode can be greatly increased.
The interval time is selected based on a winning timing of the game ball with respect to the big winning opening. If it does in this way, it can give moderate randomness to selection of interval time, and can suppress selection with biased interval time.
The interval time is selected based on the operation timing of the effect operation switch operated by the player. In this way, the number of winning prize balls in the big hit mode increases / decreases based on the operation timing of the effect operation switch, so that the operation of the effect operation switch can be urged to increase the player's participation consciousness.
In addition, during the jackpot mode, the opening timing of the ordinary electric accessory is notified in advance. In this way, the number of winning prize balls in the big hit mode can be increased or decreased according to the skill of the player. In other words, in the jackpot mode, if the game ball is continuously fired without considering the opening timing of the ordinary electric accessory, that is, the timing at which the specific winning opening is opened or enlarged, the ordinary electric accessory is released. However, since many game balls will win the upstream prize opening, there will be little increase in the number of winning prize balls due to the opening of the ordinary electric accessory, but the interval between the special electric accessory and the ordinary electric accessory When the game ball launch adjustment is made so that the opening timings of the game balls coincide with each other, a lot of game balls will win in a specific winning opening where the normal electric accessory is provided. The number of balls increases, and as a result, the total number of winning balls in the jackpot mode can be greatly increased.

  According to the ball ball game machine of the present invention configured as described above, it is possible to increase / decrease the number of winning balls in the big hit mode without increasing the number of ordinary electric accessories and to increase the gameability in the big hit mode. it can. In other words, if a short interval time is selected, many game balls will win the big prize opening on the upstream side even if the ordinary electric accessory is released. The increase in the number of prize balls is small, but if a long interval time is selected, the chances for a game ball to win a prize opening or start opening where a regular electric accessory is provided will increase. As a result, the number of winning prize balls to be increased can be increased, and the total number of winning prize balls in the jackpot mode can be greatly increased.

  In the pachinko gaming machine 1 configured as described above, when the launching handle 8 is operated while the game balls are accumulated on the upper plate 6, the game balls are launched toward the game board 4. When the launched game ball wins the start opening 14, the big winning openings 15A and 15B, the specific winning opening 16, and the like, a predetermined number of game balls are paid out as winning balls. For example, 7 winning balls are paid out when winning at the start port 14, 14 are awarded when winning at the large winning ports 15A and 15B, and 10 winning balls are paid out when winning at the specific winning port 16.

In addition, when the launched game ball passes through the gates 17A and 17B, a normal symbol lottery is performed with a predetermined winning probability (for example, 1/2), and a specified time has elapsed since the normal symbol lottery was performed. Later, the result is displayed on the normal symbol display device (effect symbol display device 21). When the normal symbol lottery is won, the normal electric accessory 16a is opened for a predetermined time (for example, 4 seconds) after the lapse of the specified time, and a specific winning opening 16 can be awarded or easily. Become.
In addition, during the digestion of the specified time, the right of the normal symbol lottery obtained by passing through the gates 17A and 17B, that is, the numerical data used for the normal symbol lottery is stored and held up to a predetermined number (for example, 4) as an upper limit. Can do.

  When the launched game ball wins the start opening 14, a special symbol lottery is performed with a predetermined winning probability (for example, low probability = 1/300, high probability = 1/30) The result is displayed on the special symbol display device 20 and the effect symbol display device 21. When the special symbol lottery is won, the big hit mode appears after the change display of the special symbol (direction symbol), and the player can acquire many prize balls. That is, during the big hit mode, an opening operation is performed to open the ball receiving piece 15c of the special electric accessory 15a to open the big winning hole 15A, and a predetermined number of game balls with respect to the big winning hole 15A (for example, 9 Piece) or when the condition of elapse of a predetermined time (for example, 30 seconds) is satisfied, the closing operation is performed to close the ball receiving piece 15c of the special electric accessory 15a to close the special winning opening 15A. The operation of making a round is one round, and a round operation (for example, 15 rounds) is repeated a plurality of times. The time from when the ball receiving piece 15c is in the closed posture to the open posture is referred to as an interval time, and the interval time is a predetermined time (for example, 4 seconds). Further, during the special symbol variation, the special symbol lottery right obtained by winning at the start port 14, that is, the numerical data used for the special symbol lottery can be stored and held up to a predetermined number (for example, 4).

Next, a characteristic configuration of the pachinko gaming machine 1 according to the present invention will be described with reference to FIG. 3, FIG. 4, and FIG. As shown in these drawings, in the pachinko gaming machine 1, the ordinary electric accessory 16a is disposed on the downstream side of the special winning opening 15A. Hereinafter, this will be specifically described with reference to FIG. A special electric accessory 15a is provided at the big prize opening 15A. The special electric accessory 15a is provided with a ball receiving piece 15c that opens and closes a special winning opening 15A by rotating back and forth with the lower end as a fulcrum. The ball receiving piece 15c does not block the flow path of the game ball P between the glass frame 5 and the game board 4 when in the closed position, and the glass frame 5 and the game board 4 when in the open position. The ball receiving portion 15d appears so as to block the flow path of the game ball P between them. The flow path of the game ball P means a flow path from the big winning opening 15A to the specific winning opening 16. When the ball receiving piece 15c is in the open posture, the game ball P flowing down toward the big prize opening 15A is received and the received game ball P is guided to the big prize opening 15A.
Note that the present invention is not limited to the structure of the ball receiving piece 15c of the present embodiment, and the structure of the ball receiving piece 15c is a game ball that flows down toward the grand prize winning opening 15A in the open posture. Any structure may be used as long as the direction in which P flows down is changed to a direction that does not face the specific winning opening 16 by the ball receiving portion 15d.

  Further, in the pachinko gaming machine 1 of the present invention, a plurality of types of interval time for the opening operation during the big hit mode of the special electric accessory 15a are set (for example, two types of 1 second and 5 seconds are set), and the interval time is set. The selection is made based on a predetermined condition. In this way, it is possible to increase or decrease the number of winning balls in the big hit mode without increasing the number of ordinary electric accessories 16a, and to increase the gameability during the big hit mode. That is, when a short interval time is selected, even if the specific winning opening 16 is opened or expanded by the opening operation of the ordinary electric accessory 16a, many game balls are guided to the ball receiving piece 15c in the open posture. Since the upstream winning prize opening 15A is won, the increase in the number of winning prize balls due to the opening of the ordinary electric accessory 16a is small. However, if the long interval time is selected, the ordinary electric accessory 16a Since the chance of a game ball winning in a specific winning opening 16 provided increases, the number of winning balls due to the release of the ordinary electric accessory 16a increases, and consequently the total number of winning balls in the big hit mode can be greatly increased. it can.

There are no restrictions on the type, length, and selection conditions of the interval time. For example, as shown in FIG. 6 as Example 1, two types of 1 second and 5 seconds are set as the interval time of the special electric accessory 15a in the big hit mode, and the winning timing of the game ball to the big winning opening 15A Based on this, the next interval time may be selected. If it does in this way, it can give moderate randomness to selection of interval time, and can suppress selection with biased interval time.
When the interval time is selected based on the winning timing of the game ball for the big winning opening 15A, the selection status of the interval time can be displayed on the effect symbol display device 21 as an effect. For example, the character string “1 second” and the character string “5 seconds” are alternately displayed while the special electric accessory 15a is being opened, and the timing at which the nth game ball wins the prize winning opening 15A. To stop display of any character string.

Further, as shown in FIG. 6 as Embodiment 2, two types of 1 second and 5 seconds are set as the interval time of the special electric accessory 15a in the big hit mode, and the effect operation switch operated by the player The next interval time may be selected based on the operation timing of S. In this way, the number of winning balls in the big hit mode increases / decreases based on the operation timing of the effect operation switch S, so that the operation of the effect operation switch S can be promoted and the player's participation consciousness can be enhanced.
When the interval time is selected based on the operation timing of the effect operation switch S, the selection status of the interval time can be displayed on the effect symbol display device 21 as an effect. For example, while the special electric accessory 15a is being opened, the character string “1 second” and the character string “5 seconds” are alternately displayed and the operation of the effect operation switch S is requested, and the effect operation is performed. Any character string is stopped and displayed at the timing when the switch S is operated.

  Further, in the pachinko gaming machine 1 of the present embodiment, the opening timing of the ordinary electric accessory 16a, that is, the timing for opening or enlarging the specific winning opening 16 is notified in advance during the big hit mode. In this way, the number of winning prize balls in the big hit mode can be increased / decreased according to the skill of the player without increasing the number of ordinary electric accessories 16a, and the gameability in the big hit mode can be improved. That is, in the jackpot mode, when the game ball is continuously launched without considering the opening timing of the ordinary electric accessory 16a, the specific winning opening 16 is opened or enlarged by the opening operation of the ordinary electric accessory 16a. However, since many game balls are guided to the ball receiving piece 15c in the open posture and win the large winning opening 15A on the upstream side, the increase in the number of winning prize balls due to the opening of the ordinary electric accessory 16a is small. However, when the game ball is adjusted so that the interval of the special electric accessory 15a coincides with the opening timing of the ordinary electric accessory 16a, many games are provided at the specific winning opening 16 provided with the ordinary electric accessory 16a. Since the balls win, the number of winning balls due to the opening of the ordinary electric accessory 16a increases, and as a result, the total number of winning balls in the big hit mode can be greatly increased.

For example, when the maximum number of winning prizes 15A in one round is nine, the game balls are temporarily stopped in a state where the number of winning prizes is less than nine, and the opening or opening at a specific winning opening 16 to be notified in advance is notified. By restarting the launch of game balls in accordance with the expansion timing, it is possible to win a large number of game balls in a specific winning opening 16 and increase the number of winning balls in the big hit mode. For example, the number of open rounds of the grand prize opening 15A is 15 rounds (interval 14), the average number of prizes in the specific prize opening 16 by one opening of the ordinary electric accessory 16a is 5, and the prize of the specific prize opening 16 When the number of balls is 10, the number of winning prize balls resulting from the opening of the ordinary electric accessory 16a is 700 (= 5 × 10 × 14), which can greatly increase the number of winning prize balls in the big hit mode. it can.
In addition, as a method of stopping the firing of the game ball, there are a method of pushing the firing stop switch 37, a method of releasing the hand from the touch sensor 36, and a method of returning the firing handle 8 to the firing stop position. Either can be selected.

Since the opening timing of the ordinary electric accessory 16a is after the lapse of the specified time since the normal symbol lottery is performed, the timing for opening or expanding the specific winning opening 16 is the elapsed time of the specified time or the specified time. By notifying the remaining time, it can be easily notified. For example, the elapsed time display of the specified time or the remaining time display of the specified time is performed on the jackpot effect screen of the effect symbol display device 21. In this way, the player can easily recognize the opening timing of the ordinary electric accessory 16a, that is, the timing at which the specific winning opening 16 opens or expands, particularly when the remaining time of the specified time is notified. This makes it possible to accurately recognize the opening timing of the ordinary electric accessory 16a even if the player does not know the specified time.
Further, during the big hit mode, it is preferable to count and display the number of winning game balls for the big winning opening 15A. For example, on the jackpot effect screen of the effect symbol display device 21, a count display of the number of winning game balls for the big prize opening 15A is performed. In this way, since the number of winning game balls for the big winning opening 15A can be accurately recognized, it is possible to easily determine the timing of stopping the game ball firing.

Moreover, it is preferable that the specified time is set to 1/2 or less of the maximum opening time of the special electric accessory 15a. For example, when the maximum opening time of the special electric accessory 15a is 30 seconds, the variation time of the normal symbol is set to 15 seconds or less. In this way, even if the normal symbol lottery is not selected, the next normal symbol lottery can be waited and the interval of the special electric accessory 15a can be adjusted to the opening timing of the normal electric accessory 16a. It is possible to suppress a decrease in the number of winning balls due to.
The specified time may be constant, but a plurality of types of specified time may be set and any one of them may be selectively used. In this way, it is possible to prevent a specific winning opening 16 from being aimed in game modes other than the big hit mode.

  Next, a gaming method of the pachinko gaming machine 1 according to the embodiment of the present invention will be described with reference to FIG. 3 and FIG. However, the game area of the game board 4 is divided into a left game area 4L and a right game area 4R, and the right game area 4R includes a gate 17A, a big prize opening 15A (special electric accessory 15a), and a specific prize. It is assumed that the mouth 16 (ordinary electric accessory 16a) is disposed, and the start opening 14 and the big prize opening 15B (special electric accessory 15b) are disposed in the left game area 4L.

  First, the player launches a game ball into the left game area 4L aiming at the start port 14. When the launched game ball wins the start opening 14, a special symbol lottery is performed with a predetermined winning probability, and the result is displayed on the special symbol display device 20 and the effect symbol display device 21. In addition, when the launched game ball passes through the gates 17A and 17B, a normal symbol lottery is performed with a predetermined winning probability, and the result is displayed on the normal symbol display device (effect symbol display device 21) after a specified time. Is done. When the normal symbol lottery is won, after the lapse of the specified time, the normal electric accessory 16a is opened for a predetermined time, and the specific winning opening 16 is opened or enlarged accordingly. In the game modes other than the above, since the advance notification of the ordinary electric accessory 16a is not notified in advance, even if the game ball is fired to the right game area 4R after the ordinary electric accessory 16a is released, there are many in the specific winning opening 16 No game balls can be won. In particular, if the time for the launched game ball to reach the specific winning opening 16 is set to be longer than the opening time of the ordinary electric accessory 16a, the targeted winning of the specific winning opening 16 in the game mode other than the big hit mode is surely prevented. can do.

  When winning the special symbol lottery and shifting to the first jackpot mode, a predetermined number of game balls (for example, nine) are won for the big prize opening 15A, or a predetermined time (for example, 30 seconds) has passed 1 The special electric accessory 15a opens as a condition for ending the round, and this opening operation is repeated a plurality of rounds (for example, 15 rounds) through a predetermined interval time (for example, 4 seconds). Launches a game ball aiming at the right game area 4R where the special winning opening 15A is provided. Here, as the interval time of the opening operation during the big hit mode of the special electric accessory 15a, a plurality of types are set, and any one of the interval times is selected based on a predetermined condition. The number of prize balls can be increased or decreased. That is, when a short interval time is selected, even if the specific winning opening 16 is opened or expanded by the opening operation of the ordinary electric accessory 16a, many game balls are guided to the ball receiving piece 15c in the open posture. Since the upstream winning prize opening 15A is won, there is little chance for a game ball to win a specific winning opening 16 provided with the ordinary electric accessory 16a, and the winning prize ball resulting from the opening of the ordinary electric accessory 16a Almost never occurs. However, when a long interval time is selected, the chances for a game ball to win a specific winning opening 16 provided with the ordinary electric accessory 16a is increased, so that the number of winning prize balls resulting from the opening of the ordinary electric accessory 16a is increased. As a result, the total number of winning balls in the big hit mode can be greatly increased.

  Further, in the pachinko gaming machine 1 of the present embodiment, the number of winning prize balls during the big hit mode can be increased or decreased according to the skill of the player. In other words, when the game ball is continuously fired without considering the timing for opening or expanding the specific winning opening 16, even if the specific winning opening 16 opens or expands, it flows down toward the specific winning opening 16. Since the game ball is guided to the large winning opening 15A disposed upstream of the specific winning opening 16 by the ball receiving piece 15c, the increase in the number of winning prize balls due to winning in the specific winning opening 16 is Few. On the other hand, in the jackpot mode, in consideration of the timing at which the specific winning opening 16 is opened or expanded, the game ball is fired so that the interval of the special electric accessory 15a matches the timing at which the specific winning opening 16 is opened or expanded. When the adjustment is performed, a large number of game balls win the specific winning opening 16 provided with the ordinary electric accessory 16a, so that the total number of winning balls in the big hit mode can be greatly increased.

For example, when the maximum number of winning prizes 15A in one round is nine, the game balls are temporarily stopped in a state where the number of winning prizes is less than nine, and the opening or opening at a specific winning opening 16 to be notified in advance is notified. By restarting the launch of game balls in accordance with the expansion timing, it is possible to win a large number of game balls in a specific winning opening 16 and increase the number of winning balls in the big hit mode.
In the present embodiment, the gates 17A and 17B are arranged in the left and right game areas 4L and 4R, and the normal symbol is released immediately after the big hit by always keeping the number of reserved symbols in the normal symbol full. However, the gate 17A may be arranged only in the right game area 4R. In this way, in the game modes other than the big hit mode, the normal symbol lottery is substantially prohibited, and it is possible to reliably prevent the specific winning opening 16 from being aimed.
