Description

  According to the present invention, when the start condition is satisfied, the symbol is displayed in a variable manner on a symbol variation display such as a liquid crystal display, and when it stops at a certain symbol with a certain probability by chance, it becomes a big hit state and a large number of game balls can be acquired It relates to a gaming machine such as a pachinko machine.

  As is well known, the so-called first type pachinko gaming machine is provided with a pattern variation display such as a color liquid crystal display, CRT, etc. on the game board surface, and when the hit ball hit by the player enters the tulip-shaped start opening, The symbols 1 to 8 and symbols such as ☆ ◆ ◎ or characters etc. are displayed on the design variation display in multiple rows (usually 3 rows) so that the symbols flow up and down or left and right respectively. When it stops in a few seconds, and the stop pattern becomes a predetermined pattern such as “222”, “777”, “☆☆☆” with a certain probability (about 1/300) by chance. When the jackpot state is reached, the open / close door of the variable winning device (large winning port) is opened by the operation of the solenoid, and a predetermined number (usually 10) of hit balls enter the variable winning device in the opened state, or Open state When the predetermined time limit (usually 30 seconds) elapses, the so-called first round is over and the variable prize-winning device is temporarily closed. During this first round, the continuous prize opening provided in the variable prize-winning device ( When a hit ball has entered the V zone), the variable winning device is opened again as soon as the second round begins, and a predetermined number of hit balls (in the opened variable winning device) ( (Usually 10), or when the predetermined time limit (usually 30 seconds) has elapsed in the open state, the second round is over and the variable prize-winning device is closed again, but continues during the second round If a ball hits the winning hole, the third round starts and the variable winning device is opened again, and the final round (for example, on the condition that the ball hits the continuous winning hole during each round (for example, 16th The variable winning device until und) is continuously open, which is constituted such that many benefits provided to the player because it can obtain a large number of prize balls when a such a jackpot status.

  In addition, in this type of gaming machine, when a big hit is made with an odd number of symbols such as “333”, “555”, and “777” (hereinafter referred to as “specific symbols”), For example, the probability is increased from 1/300 to 1/60 (in the industry, referred to as “probability”), or the opening time of the tulip starter is extended from normal 0.5 seconds to 2 seconds ( (In the industry, it is referred to as “short time”), and it is possible to give a privilege such as making it easier to establish the start condition, and there is a situation that is advantageous to the player (hereinafter referred to as “the privilege”) even after the big hit state is over What is going on is known.

By the way, since the above-mentioned benefits were conventionally started immediately after the jackpot state ended, if the bonuses were not hit by the specific symbols as described above, the benefits are not granted, Since the player's sense of expectation must be greatly reduced after the big hit state is over, there is a problem that the game itself is likely to be stopped.
An object of the present invention is to solve such problems and to provide a gaming machine that can always be played with a sense of expectation and can continue to give a sufficient interest to the player.

For this reason, the gaming machine of the present invention is controlled so that when the starting condition is satisfied, the display symbol of the symbol variation indicator fluctuates, and when it stops at a predetermined symbol, it becomes a big hit state and a large number of game balls can be acquired. In a gaming machine equipped with a control board, a predetermined period after the jackpot state ends is switched from a normal period to a special period by the control board, and advantageous benefits other than the jackpot state are determined in advance by lottery during the normal period. The special symbol is set so that advantageous benefits other than the jackpot state are generated at a higher probability than the normal period by lottery during the special period, and the display symbol is stopped at a predetermined symbol. and characterized in that when the result is not a big hit state not like drawing in drawing and該特specific period in the normal period is performed That.
Also, the gaming machine of the present invention controls so that when the starting condition is satisfied, the display symbol of the symbol variation indicator fluctuates, and when it stops at a predetermined symbol, it becomes a big hit state and a large number of game balls can be acquired. In a gaming machine equipped with a control board, a predetermined period after the jackpot state is ended is switched from a normal period to a special period by the control board, and a predetermined advantageous benefit other than the jackpot state is drawn in the normal period. In a special period, the bonus is set to be generated by a lottery other than the jackpot state and more advantageous than the normal period, and the display symbol does not stop at a predetermined symbol. When the state is not reached, the lottery in the normal period and the lottery in the special period are performed .

Thus, according to the present invention, when the start condition is satisfied, the display symbol of the symbol variation indicator changes, and when the start condition is satisfied, the display symbol of the symbol variation indicator fluctuates to a predetermined predetermined symbol. In a gaming machine equipped with a control board that controls so that a large number of game balls can be obtained when stopped , the control board is a privilege that is advantageous to the player if the display design does not stop at a predetermined design controls such that the lottery is performed to generate a predetermined period after the jackpot state is terminated and special period,該特by period probability of generating benefits set higher than normal by the lottery, also 該特by since the period of benefits generated by the lottery is set more advantageously than usual for the player, the player can always be a game with a sense of expectation, of increasing interest There is that effect.

  Next, an embodiment of the invention will be described for a pachinko gaming machine. FIG. 1 shows a front view of a game board 1 of a pachinko gaming machine. In the figure, 2 is a symbol variation display device composed of a color liquid crystal display provided on the game board 1, 3 is a normal winning opening, and 4 is a pass gate. Reference numeral 5 denotes a tulip-shaped start port provided so that a pair of blades can be opened and closed by a solenoid, and reference numeral 6 denotes an upper winning prize opening. Reference numeral 7 denotes a variable winning device comprising a large rectangular large winning opening provided below the start opening 5. The variable winning device 7 is provided with an opening / closing door 8 that is opened and closed by the operation of a solenoid. A continuous winning opening 9 is provided in the device 7. Reference numeral 10 denotes four holding display lamps provided for storing the number of hitting balls when the symbol variation indicator 2 displays the variation while the starting variation 5 is displayed and holding the starting, and 11 for hitting the passing gate 4. The normal symbol variation display (7-segment digital display device) 12 starts to change when the ball passes, and the number 12 stores the number of hit balls when the normal symbol variation indicator 11 passes through the passing gate 4 while the variation is being displayed. Four on-hold display lamps 13 are provided for holding the variable display, and 13 is a decorative lamp.

  FIG. 2 is a block diagram showing an input / output device related to the present invention connected to a control board 15 comprising a CPU, ROM, RAM, and I / O, and 20 is a passage detection for detecting a hit ball that has passed through the passage gate 4. A switch, 21 is a start switch that detects a hit ball that has won a winning opening 5, 22 is a count switch that counts the winning balls to the variable winning device 7, and 23 is a specific area that detects a winning ball to the continuous winning opening 9 The game control board further includes the symbol variation indicator 2, the hold indication lamps 10, 12, the normal symbol variation indicator 11, the decoration lamp 13, the solenoid 25 of the variable winning device 7, and the start. A solenoid 26 that opens and closes the blades of the mouth 5 is connected.

Next, the features of the present invention will be described with reference to the flowchart of FIG. In this embodiment, the starting condition is established in step (1), the change of the display symbol of the symbol fluctuation indicator 2 is started in step (2), and the privilege grant count T is 1 or more in step (3). And if it is 1 or more, after subtracting 1 from the number of privilege grant T in step (4), the probability of jackpot occurrence is high (1/30) in step (5) If the privilege grant count T is not 1 or more, the jackpot occurrence probability is set to a low probability (1/300) in step (6). In step (7), various symbol stop patterns such as the reach mode are selected and displayed on the symbol fluctuation display 2. In step (8), all symbols are stopped.

In step (9), it is determined whether or not the stop symbol is a predetermined symbol. If the symbol is a predetermined symbol, the process proceeds to step (10) to generate a big hit state. When the jackpot state ends, the privilege state is initialized in step (11), the special period K is set to 100 times in step (12), and the process returns to step (1).

If it is determined in step (9) that the stop symbol is not a predetermined symbol, the process proceeds to step (13) without a big hit state, and it is determined whether or not the special period K is one or more times. If it is once or more, after subtracting 1 from the special period K in step (14), a lottery is performed in step (15) as to whether or not a privilege is granted. Step (16). In this lottery, the probability that a privilege is granted is set to a high probability (1/100), and when it becomes a hit, the privilege grant count T is set to 100 in step (17). And it returns to step (1). If it is determined in step (13) that there is no special period K, the process proceeds to step (18) and a lottery is performed as to whether or not a privilege is to be granted. Is set to a low probability (1/1000). Further, when the lottery is a hit, the privilege grant count T is set to 30 in step (20), and the process returns to step (1).

For this reason, in this embodiment, until the number of symbol fluctuations after the end of the jackpot state reaches 100, it is a special period, and the probability that a privilege will be granted each time the symbol fluctuates changes with high probability. The benefits in the case of a bonus will be large (privilege grant count T = 100), but if it exceeds 100, the probability that a privilege will be granted outside the special period will be low, and the bonus will be It becomes smaller (privilege grant count T = 30).

And, as determined by the above step (3), since this privilege is to set the probability of occurrence of jackpot state to a high probability setting or a low probability setting, if this privilege is acquired more It is advantageous for the player.

In addition to increasing the probability of occurrence of the jackpot state as described above, the privilege content can be increased by increasing the opening time of the blades of the starting port 5 to be more normal than usual. There can be various forms such as shortening the fluctuation time of the display symbol of the symbol variation indicator, or using these benefits together.

FIG. 4 shows the transition of the jackpot occurrence probability that can be assumed in the gaming machine shown in this embodiment. In (A), when the initial jackpot occurrence probability is 1/300 of the normal, the above step (18) The bonus grant probability will be attrited and the jackpot occurrence probability will be 1/30 until the number of symbol fluctuations reaches 30 after that, and if the period passes without a jackpot occurrence, the jackpot occurrence probability is normal 1 An example of returning to / 300 is shown. In (b), when the jackpot occurs when the probability of jackpot occurrence is 1/300, and when the jackpot state ends, the process proceeds from step (13) to step (15). An example is shown in which a lottery for award grant is made with a high probability (1/100) as a special period until the number of times reaches 100. In this case, there is no change in the probability of jackpot occurrence. Also, in (c), when the lottery for granting a bonus has a high probability (1/100), the probability of jackpot rises from 1/300 to 1/30, which is a high probability state. Indicates that the number of symbol fluctuations is 100.

Thus, in the gaming machine of the present invention, even after the end of the jackpot state, the benefits are not uniformly given as in the past, and there are various aspects, so that the player always has a sufficient sense of expectation. You can continue playing with interest.
Although this embodiment has been described with respect to a pachinko gaming machine, the present invention can also be applied to a slot machine or the like. In that case, it goes without saying that a game medium such as a medal is used instead of the game ball.
