Abstract

PROBLEM TO BE SOLVED: To reduce unfairness between game players while keeping probability in the lottery of a game. SOLUTION: Random number values other than a hit random number value are simply a losing random number value and are not normally provided with any function. But a point obtaining game is generated through the use of the losing random number values. In the point obtaining game, a privilege is given on condition that ten points are obtained and a part of the losing random number values (36 random numbers) are classified into four kinds. The random number is for a two-point plus in the first classification, a one-point plus in the second classification, a one-point minus in the third classification and a zero-point in the fourth classification.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a random number value having a predetermined hit probability set by launching a game ball toward a game board surface by a launch device and prize-winning a starting port provided on the game board surface. The present invention relates to a gaming machine in which a lottery is executed, and when a random number value determined by the lottery is a hit value, a gaming state advantageous to a player can be set.

[0002]

2. Description of the Related Art Conventionally, in a gaming machine, in particular, in a pachinko machine, a lottery is performed by detecting a pachinko ball which has won a starting winning opening (special symbol starting winning opening). As a result,
There is a pachinko machine that has a function of opening a special winning opening a predetermined number of times for a predetermined period of time and increasing a winning rate of a game ball, so as to be in a state advantageous to a player.

The 0-point random number does not change in the point like the random number other than the random number used in the point acquisition game, but the effect of acquiring the point on the display unit 124 is performed (described later).

[0042]

[Table 1]

FIG. 4 is a block diagram showing a lottery control function including the point acquisition game.

The value extracting means 200 includes a random number generating means 202
Is extracted from the random number generated at the timing when the sensor detecting means 204 detects the winning timing of the special symbol starting winning opening 126 or the like. The extracted value is used by the jackpot value matching means 206 and the point acquisition matching means 208.

First, the jackpot value comparison means 206 compares the extracted value with the value in the jackpot table. The jackpot table used at this time is determined by the table selecting means 210 according to the conditions at that time.
2 and one of the high probability jackpot tables 214 are selected.

As a result of the comparison by the jackpot value comparison means 206,
When the extracted value matches the value in the table, the big hit symbol lottery means 216 selects a big hit symbol. In addition, the lottery is performed by a detection signal from the sensor detecting means 204 which receives a signal from the special symbol winning sensor 168.
After that, the variation pattern for the big hit is selected by the variation pattern selection unit 218, and the command is transmitted to each sub-control board 151 by the command transmission unit 220. At the same time, the special electric accessory control means 222 controls the operation of the special electric accessory (big winning opening 128) accompanying the big hit.

If the result of the collation by the jackpot value collating means does not match the value in the table, the branch judging means 224 selects whether or not to execute the point acquisition collating means 208. Here, the point value accumulating means 2
26, an instruction is issued to the branch determination means 224 so as not to perform the point acquisition and collation means 224 when the accumulation of the point values satisfies the reference value (10 points in the present embodiment). Further, an instruction is sent to the table selecting means to use the high probability big hit table 214.

The point acquisition and collation means 208 collates whether the value of the point acquisition table 228 and the value extracted by the value extraction means 200 match. As a result of the collation, if they match, the point value is extracted from the point value selection table 232 by the point value extraction unit 230 at the timing when the detection signal from the sensor detection unit 204 is received.

The extracted point value is added or subtracted each time by the point value accumulating means. Also, it is checked whether the reference value (10 points in the present embodiment) has been reached, and if it has been reached, an instruction is sent to other means as described above.
After that, the symbols are randomly selected using the symbol selection table (for three symbols) 234 by the off symbol lottery means 236. When the point value is extracted, the variation pattern selection unit 218 selects a variation pattern expressing the point value, and transmits a command to each sub-control board 151 by the command transmission unit 222.

When the value of the point acquisition table 228 does not match the value extracted by the value extraction means 200 by the point acquisition and verification means 208, or when the branch determination means 22
In the case where the point acquisition matching means 208 is not performed by 4, a symbol lottery is performed by the deviated symbol lottery means 236, a deviating fluctuation pattern is selected by the fluctuation pattern selecting means 218, and the command transmitting means 220
A command is transmitted to each sub-control board 151.

The operation of the present embodiment will be described below.

First, when the pachinko ball is fired, it is guided by the rail 112 and the nail 116 of the gauge portion 114 or the windmill 1
While abutting on 18 etc., it falls while moving unpredictably. Here, when a prize hole 120 is won, a predetermined number of pachinko balls are paid out (prize balls). Further, when the normal symbol starting winning port 130 is won, the normal symbol winning sensor 170 detects this.

By this detection, the main control board 150
Ordinary symbol lottery starts. That is, a number from 0 to 9 is randomly selected with a predetermined probability using a random number counter.
If the result of the lottery is off, there is no particular change in the gaming state. On the other hand, if the lottery results in a win (for example, a win number of 7 is drawn), the main control board 150 controls the electric tulip 13 provided in the special symbol starting winning opening 126.
The solenoid 174 is energized so as to open the solenoid 4. As a result, a high probability state can be achieved in which the pachinko ball easily enters the special symbol start winning opening.

When a pachinko ball wins in the special symbol start winning opening 126, a big hit lottery is started on the main control board 150 with a predetermined establishment using a random number counter. As a result of the jackpot lottery, if a win / miss is determined, a symbol variation pattern (symbol variation pattern) prepared in advance is selected (a random number counter may be selected) in each case.
A command signal is sent to a control board related to the effect including the symbol display control board 160.

The symbol display control board 160 displays a symbol variation pattern on the display unit 124 via the display driver 166 based on the received command signal. In this pattern variation pattern, there are various effects such as hitting via reach, outreach, off without reach, etc.
The player can wait for the lottery result with a sense of expectation.

Here, in the case of a hit, the opening and closing member 129 of the special winning opening 128 is opened for a predetermined time and a predetermined number of times, so that the probability of winning a pachinko ball becomes extremely large.
An advantageous state for the player can be achieved.

If a pachinko ball wins in the special symbol starting winning opening 126 during the symbol variation display, the lottery is performed at that time, but the symbol variation display currently in progress stands by until the symbol variation display is completed. . This is notified to the player by turning on the hold lamp.

In the present embodiment, in addition to the normal game, even if the result of the lottery is out of order, a privilege is obtained when the number of points that can be obtained in this case becomes a predetermined cumulative number. A point acquisition game is provided. Hereinafter, the flow of the game in which the normal game and the point acquisition game are used together will be described with reference to the flowchart of FIG.

In order to perform a lottery, a special symbol starting winning opening 1
It is checked whether or not the pachinko ball has won the prize (step 300). When the winning of the special symbol starting winning opening 126 is confirmed (affirmative determination in step 300), the value of the internal loop counter (0 to 947) is obtained, and the count value is obtained from the random number table generated in advance. Is extracted (acquired) (step 302). The extracted random number value is compared with a value of a jackpot winning table prepared in advance (step 304).

It should be noted that the game ball is a special symbol starting winning opening 126
, The lottery is already in progress, the result of the lottery has not been notified to the player, and another game ball has won the special symbol start winning prize port 126 (a state in which there is a so-called hold start). In the meantime, the random number for the subsequent start winning is not immediately compared with the big hit winning table in the above step 304, but is temporarily stored in a predetermined buffer (a memory not shown) and the lottery result for the previous starting winning is obtained. Are notified to the player, and are sequentially read from the buffer and processed as described above.

In step 306, it is determined whether or not the result of the comparison is a match or not. In the present embodiment, the matching probability is 3/948, and otherwise, there is no match.

If it is determined in step 306 that they match, the privilege flag is cleared (step 308).

Next, in step 310, a lottery of a winning symbol is performed, and then a lottery condition of a fluctuation pattern is created (step 312), and a lottery of the fluctuation pattern is performed (step 314).

In the next step 316, the variation pattern
The symbol data, the point data, and the like are stored in the memory, and based on the stored data, a command is transmitted to the sub-control board 151 such as the symbol display control board 160, and a process at the time of a big hit is performed.

On the other hand, if it is determined in step 306 that the extracted value does not match the jackpot table, the process compares in step 318 with the point winning table. In the present embodiment, the probability of coincidence with the point winning table is 36/948, and the others are inconsistent. This probability is a probability that is more than 10 times more likely to match with the jackpot winning table.

If it is determined in step 320 that the values match the point winning table, a lottery of point values is executed in step 322. In the lottery method, 36 types of random numbers are classified into 4 types, and a point value corresponding to this classification is extracted. In the present embodiment, +2 points with a probability of 3/36, +1 points with a probability of 9/36,
1 point with a probability of 6/36, 0 with a probability of 18/36
The setting is such that 9 points can be obtained by 948 rotations as an expected value. If the current acquired point is 0 or less, it is assumed that the value does not become negative any more.

The points obtained as a result of the lottery are added to or subtracted from the currently acquired points. If the result exceeds 10 points, a privilege flag is set (step 32).
4).

In step 326, when a point is given (including 0 point), it is necessary to display a variation pattern that allows the player to know the point, so that conditions are created. Next, step 32
In step 8, a lottery for a missing symbol is performed.
In step 3126, a lottery of a variation pattern is performed.
To store the variation pattern, symbol data, point data, etc. in the memory.

If the extracted (acquired) random number value does not match the point winning table in step 320, the process proceeds to step 330 to create lottery conditions for a variation pattern for deviation, and lottery for a deviation symbol. Is performed (step 328).

If the number of points stored in the memory in step 316 is 10, the bonus hit table is changed to a high probability table as a privilege for the player, thereby increasing the probability of the big hit. As a result, the player has a higher probability of winning than before, and can continue the game with a sense of expectation. In addition, unfairness to other players can be reduced.

The bonus to the player may be an increase in the probability of winning the special symbol starting winning opening 126 (easiness of winning), in addition to increasing the probability of the winning lottery. In this case, the flow path for guiding to the special symbol starting winning opening 126 may be widened or narrowed, or a new starting opening in another place may be provided and the opening thereof may be opened and closed. . In this case, the color of the holding lamp for distinguishing from the normal winning may be changed according to the winning place and the winning condition.

Further, in this embodiment, the value extracting means 2
00, the values extracted by the random number generation means 202 and the sensor detection means 204 are used by both the jackpot value collation means 206 and the point acquisition collation means, but are respectively different value extraction means, random number generation means, sensor detection means May be provided to operate in a similar manner.

Further, in the present embodiment, the display of the point value is interlaced with the fluctuation pattern and displayed.
Another display form may be used. For example, the main control board 15
In the case of 0, the special symbol starting winning opening 126 is won, and when the lottery is executed and the obtained random number value falls into the first to fourth categories in Table 1, the effect according to each category is displayed on the display unit 124. A command signal is output to the symbol display control board 160 so as to be executed. In the display unit 124,
Display a roulette-shaped image, +2 along the outer circumference,
A simple game in which indices of +1, -1, and ± 0 are displayed, the pointer is moved at a high speed, the speed is gradually reduced, and the finally stopped index is set as an acquisition point may be used. In this case, the effect itself on the display unit 124 is not performed only when the random number value obtained first corresponds to the first to fourth classifications in Table 1 above. , And ± 0 in the classification.

[0074]

As described above, the present invention has an excellent effect that it is possible to reduce unfairness among players while maintaining the probability of a lottery in a game.
