Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a pachinko game machine,
The present invention relates to a ball game machine such as an arrangement ball game machine and a sparrow ball game machine, and a simulation game program for these. Representatively, ammunition provided for the operation of pachinko-ya and store No. 8 of Article 2, Paragraph 1, Item 7 of the Act on Regulation of Customs Sales Business and Regulation of Business (hereinafter referred to as the "Management Law") The present invention relates to a ball game machine, a new or used article for which these are designed for general users, and a simulation game program for executing these simulation games on a personal computer or a game machine.

[0002]

2. Description of the Related Art Many ball-and-ball game machines such as pachinko game machines have special equipment for facilitating prizes in order to appropriately stimulate a player's gambling spirit. Articles), which are operated under predetermined operating specifications to increase the fun of the game. In particular, a player tends to enjoy a game in expectation of a so-called jackpot, which is an operation of a special electric accessory that opens a special winning opening in association with a combination display of a specific symbol or the like.

[0003] This jackpot is determined by a lottery according to a predetermined winning probability that a random number value read at an arbitrary timing of winning at the starting port is hit or miss by mainly software processing on a microcomputer incorporated in the gaming machine. Never based on processing. This is a so-called perfect probability method.
As a result, a jackpot cannot be arbitrarily acquired only by the skill of the player, and a way to win equally for all is opened.

[0004]

However, in the perfect probability method, good or bad luck greatly affects winning and losing, and a lucky player can quickly win a jackpot, while a bad luck player can play for a long time. Even if you do, you may not be able to win the jackpot and fall into a so-called big hamari. A player in this state of great humor not only has no interest at all, but also has a large loss due to the investment in passing through a rented ball, and gradually loses interest in the game. On the store side as well, players who continue to play games with the expectation of recovering the great hamari are good customers, and their divergence in gaming will lower the operating rate of the gaming machine and lead to loss on the store side.

[0005] The present invention remedies the disadvantages of a lucky player without causing the lucky player to feel particularly dissatisfied,
It is an object of the present invention to provide a sounder and more interesting ball game machine and a simulation game program thereof.

[0006]

According to the first aspect of the present invention,
In order to solve the above-mentioned problem, based on a lottery process according to a predetermined winning probability, at the time of winning, in a ball game machine that activates an accessory for facilitating winning of a game ball, the ball related to the number of launched balls of the game ball In addition to providing a recording means related to the number of shooting spheres for recording, when the recorded value of this recording means reaches a predetermined value,
Probability improving means for increasing the winning probability in the lottery process is provided. The accessory is typically an electric accessory that operates mainly by electric power. A first-class special electric accessory that opens or enlarges the entrance of the special winning opening, and operates when a specific symbol combination is displayed, and opens or enlarges the entrance of the special winning opening. The second or third type special electric auditors, which are activated when a game ball wins a specific winning opening, which opens or expands a winning opening other than the large winning opening, and the gaming ball is a specific winning opening. Rules concerning the certification of gaming machines and the verification of model types, etc., which are rules related to the Wind Management Act, such as ordinary electric accessories, etc., that operate when a prize is passed or passed through a specific gate, or when a specific combination of symbols is displayed (Showa 60 Includes various accessories stipulated in the National Public Safety Commission Regulation No. 4). As a result, when the number of shot balls increases beyond a predetermined value after playing a game for a long time, it becomes easier to win in the lottery process. For this reason, the disadvantage of the unlucky player can be remedied to a certain extent, and the player can be prevented from leaving the game. At the same time, the operating rate of the gaming machine is improved.

According to the second aspect of the present invention, in order to accurately evaluate the actual disadvantage of the player, the recording means is not effectively supplied to the game board from the number of shot balls fired from the firing device. The number of foul balls and / or the number of winning balls on the game board were excluded and recorded. As a result, it is possible to appropriately protect a disadvantaged player without excessively protecting a player who makes many mistakes or a player who has benefited from winning a certain amount.

According to a third aspect of the present invention, there is provided an out-ball which misses a prize on a game board, instead of the "recording means relating to the number of shot balls for recording the number of shot balls" in claim 1. Out-ball-number-related recording means to keep a number-related record "
Was provided. The number of out-balls is the number of balls that were effectively supplied to the game board and did not win, so the detection mechanism, detection circuit, or detection process could be simplified while accurately assessing the actual disadvantage of the player. Can help this person appropriately.

According to a fourth aspect of the present invention, the "recording relating to the number of launches of the lottery process" is replaced with the "recording means relating to the number of launching balls for recording the number relating to the number of launching balls". Recording means relating to the number of lottery start times to be taken. " Since the number of times the lottery process is started, if the start winning is temporarily frequent, if the winning memory is limited to, for example, a maximum of four, the starting winning number ignored from the start of the lottery process due to the limitation. Is excluded, which means the number of times the lottery is actually started. As a result, while being able to accurately evaluate the actual disadvantage of the player, it is possible to relieve the disadvantage of a player who has not been successfully won even after receiving lottery to a certain extent.

[0010] In the invention according to claim 5, even if the number of hits is theoretically expected to be reduced, the probability improving means can appropriately rescue a player who does not easily hit. When the value recorded by the recording means exceeds the evaluation value based on the theoretical base value of the winning probability in the lottery process, the operation is performed. For example, the change range of the random number is 0 to N
-1, If the number of random numbers to be won or the range of random numbers is B, the theoretical winning probability is B / N = 1 / (N / B), so (N / B) is the theoretical basis of the winning probability. Value. In this way, if the evaluation value based on the base value is exceeded, it is easy to win, so that the player can be appropriately rescued.

[0011] In the invention according to claim 6, in order to provide detailed support according to the so-called depth of the hook, the probability improving means evaluates the recorded value of the recording means in a plurality of steps,
The winning probability in the lottery process is sequentially increased. As a result, it is possible for a player who does not easily hit the ball to eventually win, and almost no other player feels unfair.

According to a seventh aspect of the present invention, in order to ensure fairness by objectively rescuing a lucky player, the recording means returns the recorded value to an initial value at the time of winning in the lottery process. And As a result, the objectivity and fairness can be ensured without continuously giving the benefit to the player who has once won the benefit by the benefit of the probability improvement.

[0013] The invention according to claim 8 is to notify the player that he / she is patient for a while and to effectively prevent giving up in the middle of the game. Is provided to the player. In addition to the visual notification using a lamp, an LED, a liquid crystal screen, or the like, the notification includes various types of notification such as notification by voice, notification by vibration, and a combination of two or more of these. As a result, the player is notified that the probability has been improved, so that it is possible to reduce the adverse effect of wasting the accumulation of the records so far and stopping the game, thereby further protecting the player.

According to a ninth aspect of the present invention, there is provided a simulation game program carried on a recording medium such as a ROM cartridge, a CD-ROM, a DVD, or the like, or distributed under a network environment such as the Internet or satellite communication. The same disadvantageous situation as the game is to be remedied. That is, based on a lottery process according to a predetermined winning probability, at the time of winning, is a simulation game program of a ball game machine that activates an accessory for facilitating winning of a game ball, and cumulatively with the progress of the game A recording step of recording a cumulative variable whose value is updated, an evaluation step of comparing the recorded value of the cumulative variable in this recording step with a predetermined evaluation value, and the recorded value of the cumulative variable is This is a simulation game program that has a probability improving step of increasing a winning probability in the lottery process when the evaluation value is reached, and causing a computer to execute these steps.

Main board 100
The award ball detection switch 41 for detecting the number of award balls is input to the award ball control board 400.

FIG. 6 shows a part of the program stored in the ROM of the main board 100, which constitutes a recording means relating to the number of shot spheres and a probability improving means based thereon. The recording of the number of shot balls is performed by adding and subtracting a shot ball counter that secures 2 bytes in the RAM. Launch ball switch a
A launch ball is detected at 1 and a2 and a foul ball switch a
If no foul ball is detected in step 3, the counter value is incremented by one and added. Note that the upper limit value of the counter is, for example, 16383, and when this value is reached, no further addition is performed. Starting port switch b1 or winning port switch c1
When a winning ball is detected in any one of .about.c4, the firing ball counter is decremented by minus one. If the counter is at the lower limit value 0, it is not subtracted.

While the recorded value of the shooting ball counter is 0 to 5000, which is not more than the first evaluation value, for example, 5001 or more, the jackpot probability remains at, for example, 1/310 of the normal theoretical value, and no notification is given when the probability is improved. When the first evaluation value reaches, for example, 5001 or more, the jackpot probability is set to, for example, 1/103, and the notification A “alternate lighting” at the time of the probability improvement described later is selected and activated. When the second evaluation value reaches, for example, 7501 or more, the jackpot probability is set to, for example, 1/31, and the notification B when the probability is improved is made.
Select “up and down lighting” and start. For example, 1 of the third evaluation value
When it reaches 0001 or more, the jackpot probability becomes, for example, 1/1.
It is set to 0, the notification C “rotation” at the time of the probability improvement is selected and activated.

As shown in FIG. 7 (A), when the number of fired balls, that is, the actual number of outgoing balls excluding foul balls and winning balls, is between 0 and 5000, there is no benefit in improving the probability. For example, when the range of the random number for jackpot determination is 0 to 309, the number of jackpots is one, and the theoretical jackpot probability is 1/310. However, the number of actual launch balls is 500
When it becomes 1 to 7500, the number of jackpots is increased to three, and the theoretical jackpot probability is increased to about 1/103. Further, when the number of actual launch balls reaches 7501 to 10000, the number of jackpots is increased to 10, and the theoretical jackpot probability is increased to 1/31. In addition, the number of actual launch balls is 1000
When it is 1 or more, the number of jackpots is increased to 31, and the theoretical jackpot probability is increased to 1/10.

Incidentally, instead of the number of shot balls, the probability may be improved based on the detection of the out ball switch d1. In this case, the processing in the recording means is only a simple addition processing of the out-ball counter used in place of the firing-ball counter, and is simplified. Further, as shown in FIG. 7B, the probability may be improved based on the actual number of lottery activations associated with the winning of the starting port 80, instead of the number of shot balls or the number of outgoing balls.

FIG. 8 shows an embodiment of the notifying means for notifying the operation when the probability is improved. The alternate lighting of A indicates that the outer decorative LED group (L1, L2, L31, L41, L5
1) and the decorative LED group inside (L61, L6)

FIG. 9 shows a part of the program stored in the ROM of the main board 100 and constitutes a processing means of a game relating to the special symbol display device 7 and the special winning opening 70. If there is a winning memory in the starting opening 80 (S1) and the random number extracted at the time of the starting winning is a big hit value (S2), the winning symbols to be aligned in the middle left and right are, for example, numbers and numbers 1 to 9 One of the character figures is determined and (S
3) One of a plurality of preset effect modes to be displayed at the time of symbol change is selected from a plurality of preset modes (S4). At this stage, the jackpot is promised and the winning is determined, so that the record of the recording means such as the above-mentioned shooting ball counter is returned to the initial value 0 (S
5). On the other hand, if the random number extracted at the time of the start winning is not a jackpot value, two or three types of symbols that are not aligned are determined (S6), and the off-state effect to appear at the time of symbol change is selected from among a plurality of preset modes. Select one from (S
7).

After the above pre-processing, the special symbol display device 7
Above, the variable display processing of the symbols is started (S8), and after the lapse of a predetermined variable display time almost determined in the effect mode accompanying the variable display, all the stopped symbols are determined (S9). It is determined whether or not the jackpot is determined based on the presence or absence of the jackpot flag set in the preceding step (S10). If the jackpot is a jackpot, the image of the jackpot fanfare sound and the blessing is output (S11), and the jackpot 70 is opened (S10).
12). When the special winning opening 70 is opened once, the special winning opening 70
If there are 10 winnings (S13), or if 30 seconds elapse after opening (S14), the big winning opening 70
Is closed (S15). The detection by the V detection switch b3 is performed during opening of the special winning opening 70 (S16), and when the final round, for example, does not exceed 15 rounds (S17), the continuous operation device for the accessory is activated, and the special winning opening 70 is closed again. open.
When the final round is exhausted for the V prize, after the ending processing for notifying the end of the jackpot by sound and display (S
18) Return to the normal game.

Then, during or after the couple is moving, the middle symbol that is different from the reach symbol is stopped together with the encouragement display that is to be determined this time. The screen 65 is an example of a confirmation screen of the out of normal reach. Of course, in the case of a hit, the middle symbol may suddenly stop at the reach symbol from the normal reach and the big hit may be displayed. Otherwise, after screen 6, the couple passes by the ramen shop (screen 7) and stops in front of the restaurant (screen 8). In the case where it is also out of here, the screen 85
Then, the middle symbol is stopped at a symbol different from the reach symbol together with the wording of the female character "This shop is unpleasant". The screen 85 is an example of a confirmation screen indicating that the normal reach is out of development. In addition, even in the normal reach development type, in the case of a hit, the middle symbol may stop at the reach symbol and a big hit may be displayed.

FIG. 12 is a continuation of the previous screen 8, in which the couple comes out of the restaurant (screen 9) and starts moving again (screen 10). However, in the case of departure, the screen 105
Then, during or after the couple is moving, the middle symbol that is different from the reach symbol is stopped together with the encouragement display that is to be determined this time. The screen 105 is an example of a long-reach confirmation screen. Of course, at the right time, even from the long reach type,
In some cases, the middle symbol stops at the reach symbol and a big hit is displayed. In other cases, after screen 10, the couple stops in front of the hotel (screen 11) and displays a man's "Nay I'm Okay" dialog at the hotel entrance (screen 1).
2). Here, in the case of departure, the screen shifts to the screen 125, and the middle symbol is stopped at a symbol different from the reach symbol together with the words "Welcome home" of the female character. The screen 125 is an example of a confirmation screen of long-reach development departure. In addition, even in the long reach development type, in the case of a hit, the middle symbol may stop at the reach symbol and a big hit may be displayed.

FIG. 13 is a continuation of the previous screen 12, in which the couple enters the hotel and temporarily stops the middle symbol with the reach symbol (screen 13). Although it is rarely here, in the case of departure, the screen shifts to the screen 135, the vacancy changes to full, the heart is cracked, the jackpot is displayed instead of the jackpot, and the middle symbol is the reach symbol. It changes to a different pattern. The screen 135 is an example of a confirmation screen of the loss of premium reach. In the case of a hit, a heart symbol and a big hit are displayed after the screen 13, and the big hit determination screen is displayed (screen 1).
4). After the jackpot determination screen is displayed, the process proceeds to the jackpot fanfare processing (FIG. 9) and thereafter. After the departure determination screen is displayed, if there is a starting prize memory, the screen starts again from the screen 1; The screen returns to the normal screen (screen 1 only including the background excluding the character and displaying the previous stopped symbol).
