Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine such as a pachinko machine and a slot machine, and more particularly, to a numerical value issued within a predetermined range by a numerical value generating means. The present invention relates to a gaming machine that determines whether or not it is a numerical value of a region and controls a gaming operation based on a determination result.

[0002]

2. Description of the Related Art In a gaming machine of this kind, a numerical value generating means such as a numerical value generating circuit or a numerical value generating program generates a numerical value within a predetermined period and within a predetermined range.
It is determined whether or not the result of extracting the generated numerical value at a predetermined timing is a numerical value of a winning region set at a predetermined position in the above range. Specifically, for example, regarding a result of extracting a numerical value generated in the range of 0 to 65535 with 16 bits, whether or not the numerical value of a winning area of 0 to 18000 including a winning such as a big hit, a middle hit, a small hit or not is determined. Is determined. If it is determined that the value is in the winning area, the entrance gate is released for a predetermined period in the case of a pachinko machine according to the winning content (big hit, medium hit, small hit, etc.) corresponding to the value. In the case of a slot machine, a predetermined number of medals are paid out, or the winning probability is increased only for a predetermined period.

[0003]

By the way, in a conventional gaming machine having such a configuration, an illegal operation such as forcibly generating a numerical value in a winning area to the numerical value generating means, or the numerical value is continuous. If an unauthorized operation is performed that causes the gaming machine to misrecognize as if
Winning will be unduly continued. Nevertheless, among the numerical values that occur, particularly, the minimum value and the maximum value in the above-mentioned range are more likely to be illicitly operated than other numerical values.

For example, in a numerical value generating circuit as the numerical value generating means, generally, a count value which is counted up in a predetermined period by a combination of a pulse generating circuit for periodically generating a pulse and a general-purpose counter such as LS161. Generate. This general-purpose counter is originally provided with a reset signal receiving terminal for resetting the count value to zero. Therefore, after a reset signal is forcibly input to the reset signal receiving terminal from outside the gaming machine by some means, the conduction from the pulse generation circuit to the numerical value generation circuit is cut off, or the forced input is continuously performed. If performed, the minimum value is zero (0)
Occur continuously.

For example, if an unauthorized operator cuts off the conduction from the pulse generating circuit to the numerical value generating circuit at an appropriate timing, the numerical value at that time can be continuously generated. Since the cutting is performed at the timing, it is not known what numerical value can be continuously generated. However, since the moment (timing) at which the maximum value is reset to zero can be specified by an extremely simple external circuit, the maximum value can be intentionally continuously generated immediately before this timing. Therefore, an unauthorized operation that continuously generates the maximum value is more easily performed than an unauthorized operation that continuously generates another numerical value (excluding the minimum value).

[0006] The present invention has been made in view of the above background, and an object of the present invention is to provide a gaming machine capable of reducing the occurrence of improper winning due to an illegal operation.

[0007]

In order to achieve the above object, a first aspect of the present invention is a numerical value generating means for generating a numerical value within a predetermined range from a minimum value to a maximum value; Means for extracting a numerical value issued by the means at a predetermined timing, and a winning determination means for determining that the winning is a win when the extraction result is a numerical value of a winning area defined in the range; A game operation control means for controlling a game operation based on a game machine, characterized in that, as the corresponding selection judging means, those in which the minimum value and the maximum value are respectively set in a non-winning area are used. It is.

[0008] In this gaming machine, the minimum value and the maximum value in the numerical range from the minimum value to the maximum value where the above-described illegal operation is particularly easy to perform are set in the non-winning area. For this reason, even if the winning determination means continues to recognize the occurrence of the minimum value or the maximum value, the winning determination is not performed. In such a configuration, the minimum value and the maximum value that are particularly likely to be illegally operated are not recognized as being won even if the winning determination unit recognizes the occurrence of the illegal operation. Can be reduced.

According to a second aspect of the present invention, in the gaming machine of the first aspect, the winning determination means is configured to change a position of the winning area within the range at a predetermined timing. It is.

In this gaming machine, the position of the winning area is changed within a range excluding the minimum value and the maximum value in a numerical range from the minimum value to the maximum value. In such a configuration,
Even if only a predetermined numerical value different from the minimum value or the maximum value is continuously generated, a winning or a non-winning is generated. Therefore, by some means, an illegal operation such as forcing the numerical value generating means to continuously generate a predetermined numerical value different from the minimum value or the maximum value, or forcing the winning determining means to continuously generate the numerical value. Even if an illegal operation is performed to make the player recognize, a situation in which the winning is continuously generated is avoided. As a result, it is possible to suppress the continuous occurrence of unreasonable winnings due to these unauthorized operations.

According to a third aspect of the present invention, in the gaming machine according to the first or second aspect, the winning area is constituted by a plurality of discontinuous areas within the range excluding the minimum value and the maximum value. Things.

In this gaming machine, the numerical value generating means is configured to generate a count value that increases by one at a predetermined timing for the following reason, and the numerical value is generated based on the operation of the player. Even if the winning determination means is configured to extract the numerical value from the generating means, it is possible to make it difficult for the player to know the timing at which the winning occurs. That is, in such a configuration, the count value generated by the numerical value generation means increases by one at a predetermined timing, and when the count value reaches the maximum value, the count value is reset to the minimum value and then starts increasing by one again. The count value is, for example, 0 to 6
It occurs within the numerical range of 5535, and in this numerical range, the winning area including the big hit, the middle hit, the small hit, and the like is 200.
Assume that it is set to ~ 18000. Then 2
There is a possibility that a numerical value corresponding to any one of 00 to 18000 may be generated periodically and with a length that can be known to the player, for example, a numerical value generated every few seconds with a length of several msec. For this reason, for example, when a jackpot occurs at an extremely short length of several nsec every few seconds, any one of a jackpot, a medium jackpot, and a small jackpot occurs without being known to the player. There is a risk that the timing of the execution will be known. Therefore, in the present gaming machine, the winning area is not set as one continuous area within the numerical value range, but is set to, for example, 200 to 400, 601 to 800, 1001 to 1200.
For example, a plurality of non-continuous areas are set. In such a configuration, the winning period in which any of a plurality of winning contents can be won is constituted by a plurality of discontinuous periods, so that the length of each of these periods is not known to the player. Becomes possible. This makes it difficult for the player to know the timing at which the winning occurs.

FIG. 2 is a schematic configuration diagram showing the internal structure of the slot machine 1. Inside the housing main body 2, three reels 16a, 1 on which a plurality of symbols are printed on the outer peripheral surface are provided.
A reel unit 16 having 6b and 16c is incorporated. Further, a main control circuit board 17 in which an electronic circuit is formed by a CPU, a ROM and other various electronic components, a medal payout device 18 as a payout unit having a medal hopper 18a capable of accommodating a large number of medals, and a reset switch 19a.
Setting operation unit 1 having a step setting key switch 19b
9. Medal stock container 20 for storing medals
And so on.

The reset switch 19a and the stage setting key switch 19b are used to set a lottery table, which will be described later, to one having a high winning probability of "big hit" or "medium hit" or to set it to a low one. It is. While the stage setting key switch 19b is tilted to the ON position,
When a main switch (not shown) is turned from OFF to ON, control in the step setting mode is performed. In this stage setting mode, each time the reset switch 19a is pressed, the stage mode sequentially changes, for example, from 1 to 6, and the corresponding lottery tables of the winning probabilities are set as those of the general gaming state. . The display of the stage mode is
This is done on the payout indicator.

The reels 16a, 16b, and 16c (hereinafter, also referred to as left reel, center reel, and right reel) are each driven to rotate by a reel driving motor (not shown) constituted by a stepping motor.
On each of these reels, seven types of symbols shown in FIGS. 3A to 3G are printed in a predetermined order. Hereinafter, these symbols are referred to as “red 7”, “blue 7”, “BAR”, “watermelon”, “bell”, “cherry”, and “plum”, respectively.

FIG. 4 is a detailed front view showing a part of the front panel 3. As shown in FIG. In the drawing, the reels 16a, 16
The symbols for about three frames at the predetermined rotation positions b and 16c are visually recognized through the display window 4. In this display window 4, five winning lines crossing the reels 16a, 16b, and 16c are drawn, and a symbol combination of a top row, a middle row, a bottom row, a right diagonal top row, and a diagonally right bottom row are respectively arranged. Is shown. When a predetermined combination is established on these winning lines, medals are paid out to the medal tray or a prize such as replay is granted to the player. In the slot machine 1 according to the embodiment, five pay lines are provided, but the number of pay lines may be smaller or larger.

The line display section 12 includes a 1MEDAL lamp 12a, two 2MEDALS lamps 12b, two 3MEDALS lamps 12c, and a start lamp 12d.
And so on. The 1MEDAL lamp 12a is arranged on an extension of the pay line in the middle row among the five pay lines in the display window 4. Also, two 2
The MEDALS lamps 12b are arranged side by side in the upper row,
It is arranged on the extension of the winning line in the lower row.
Further, the two 3MEDALS lamps 12c are arranged on the diagonally upper right and the extension of the winning line arranged diagonally below the right, respectively.

The count display section 14 includes a credit display 14a, a bonus count display 14b, a payout display 14c, and the like.

The BET operation unit 15 has a 1-BET button 15a, a 2-BET button 15b (located at the back of 15a in the figure), a Max-BET button 15c, and the like.

The game display section 13 includes a replay lamp 13a, a winning lamp 13b, a game over lamp 13
d, a BB lamp 13e, an RB lamp 13f, a medal insertion lamp 13g, and the like. When a "big hit", a "medium hit" or a "small hit" other than a replay is won, the winning lamp 13b is lit. When a “small hit” called a replay is won, the winning lamp 13
The replay lamp 13a is turned on instead of b. When a "big hit" or a "medium hit" is won, the BB lamp 13e and the RB lamp 13f are turned on in addition to the winning lamp 13b. Also, before the game started,
When a medal can be inserted, the medal insertion lamp 13g blinks.

When a medal (not shown) is inserted into the medal slot 5 by the player, the medal falls through the passage (not shown) to the medal hopper 18a (see FIG. 2). A drop hole for dropping medals smaller than the prescribed size and returning to the above-mentioned medal payout lot 10a (see FIG. 1) is provided in this passage. There are provided a medal block solenoid, a medal insertion sensor composed of a photosensor for detecting each passed medal one by one, and the like. The medal detection signal output from the medal insertion sensor that has detected the medal is sent to the main control circuit board 17 (see FIG. 2).

When the inserted medal is detected by the medal insertion sensor, the 1MEDAL lamp 12a is turned on and the start lamp 12d blinks.
The lighting of the 1MEDAL lamp 12a indicates that, out of the five pay lines, only one pay line in the middle row is activated. If a "role" is not established on the activated pay line as described above, no win is made even if a win is established on another winning line. The blinking of the start lamp 12d indicates that the game can be started. When the start lever 6 (see FIG. 1) is operated by the player in this state, the rotation of the reels 16a, 16b, 16c starts.

When another medal is inserted before the start lever 6 is operated and is officially received, one 1ME
In addition to the DAL lamp 12a, the above two 2MEDALs
The S lamp 12b is turned on. Thereby, in addition to the pay line in the middle row, the pay line in the upper row and the lower row are also effective. When one more medal is inserted and is officially accepted, two more 3MEDAL
The S lamp 12c is also turned on, and all five pay lines are activated.

As medals are further inserted, the display of the credit indicator 14a, which has been "0" until then, changes to
It increases by one for each insertion. The maximum number of medal credits is 50, and when the number reaches 50, the medal block solenoid is activated and no more medals can be accepted.

When the medal credit is one or more, the player can press the BET button instead of inserting a medal to activate the pay line and make the game possible. However, if the medal credit is smaller than the number corresponding to the pressed BET button, only the pay line corresponding to the medal credit is valid.

When the start lever 6 is operated by the player, the CPU of the main control circuit board 17
The rotation drive of the reels 16a, 16b, 16c is started. Also, a numerical signal is extracted from a numerical value generating circuit (not shown).

A predetermined rotation position of each of the reels 16a, 16b, 16c is detected by a reel position sensor such as an encoder (not shown).

The CPU of the main control circuit board 17 compares the data of the numerical signal extracted from the numerical value generating circuit with the lottery table stored in the ROM immediately after the start of reel rotation. This lottery table associates all numerical values that can be generated from the numerical value generation circuit with winning modes ("small hit", "medium hit", "big hit", "replay") and "losing". By being associated in this way, various winning modes are internally won with a predetermined probability, respectively, or "losing" occurs with a predetermined probability. Therefore, the main control circuit board 17 has a function as a winning determination unit.

The above numerical value generating circuit does not randomly generate each numerical value, but increases by one at a very short period such as several msec. A count value that changes regularly, such as restarting the increase of the count value, is generated. However, the timing of extracting the numerical value from the numerical value generating circuit is the moment when the start lever 6 is accidentally operated by a player who cannot visually recognize the sequentially generated count value. Therefore, each numerical value is randomly extracted from the numerical value generating circuit, and the extracted numerical value has a property as a random number.

Stop buttons 7a, 7 during the rotation of each reel
When b and 7c are pressed by the player, “pull-in” control and “kick-off” control are performed based on the pressing timing and the lottery result (the determination result by the main control circuit board 17). Specifically, the symbol corresponding to the internally won prize mode is not on the activated prize line when the stop buttons 7a, 7b, 7c are pressed, but is within the pull-in range of, for example, four frames on the rotation upstream side from this. In this case, “pull-in” control is performed. Thereby, after the symbol corresponding to the internally won prize mode is drawn on the prize line up to four frames, the reels 16a, 16b,
The rotation of 16c stops. In addition, even if the "miss" has been drawn, if any "role" is likely to be formed on an effective pay line, the reels 16a, 16b, 16c are additionally rotated, for example, up to four frames. The symbol corresponding to the "role" is skipped from the winning line.

When the reels 16a, 16b, 16c stop rotating and a "role" is established on an effective pay line, a winning is achieved, and the replay lamp 13a, the winning lamp 13b,
Of the BB lamp 13e and the RB lamp 13f, the one corresponding to the "role" is lit. Also, the medal lamp at the position corresponding to the winning line in which the "role" has been established blinks. For example, when the "bells" are aligned on the bottom horizontal pay line, the winning lamp 13b is lit,
Of the two 2MEDALS lamps 12b, the one on the lower side in the figure blinks.

When a prize is generated, the count display section 1
The payout indicator 14c of No. 4 displays the number of medals to be paid out corresponding to the winning mode, and the medal credit of the credit indicator 14a is increased by that amount. However, when the increasing medal credit reaches 50, the medal payout device 18 pays out the remaining medals instead of the medal credit no longer increasing.

When a valuable unit such as a prepaid card is inserted into the slot machine 1, a medal credit is added to the slot machine 1 in an amount corresponding to the value of the valuable unit, or the card unit is added to the medal tray. A medal may be paid out.

In the slot machine 1, a game is provided in a game state called a general game state immediately after a main power supply (not shown) is turned on. In this general game state, "watermelon-
"Watermelon" consisting of "watermelon-watermelon", "bell role" consisting of "bell-bell-bell", "cherry role" consisting of "cherry-regardless of design-regardless of design", "plum-plum-plum" The various "small hits" to be won by the formation of the "plum combination" are internally won with a predetermined probability. In addition, “red 7-red 7-red 7”
"Blue 7-Blue 7-Blue 7"
The BB that wins due to the formation of “role” is, for example, 1/250
With a relatively low probability of winning inside. Furthermore, "BA
A winning RB is internally won with a low probability of, for example, 1/400 by the establishment of the “BAR role” composed of “R-BAR-BAR”.

The following Table 1 shows the relationship between winning modes, winning combinations, and payout medals in the general gaming state of the slot machine 1.

[Table 1]

As shown in Table 1, in the general gaming state, "cherry role" composed of "cherry-ANY-ANY", "watermelon role" composed of "watermelon-watermelon-watermelon", and "bell-bell-bell" , Four types of “small hits” are individually defined corresponding to the “bell role” composed of “” and the “replay role” composed of “plum-plum-plum”. Also, “Blue 7-Blue 7-Blue 7”
BBs corresponding to “role 7” and “red 7-red 7-red 7” are defined. Furthermore, "BAR-BAR
RB corresponding to the “BAR combination” composed of “-BAR” is defined. Note that “ANY” indicates that any pattern may be used.

If any of the "cherry role", "watermelon role", "bell role", and "replay role" is established on the activated pay line and "small hit" or "replay" wins, 2
5, 5, 8, or 0 medals are paid out.
Note that when the “replay combination” is established, medals are not paid out, but the replay of the game under the same medal insertion conditions is permitted.

On the other hand, if "blue 7 role" or "red 7 role" is established on the activated pay line and the BB wins, 15 medals are paid out (including the addition of medal credits,
The same applies to the following), the game state is switched from the general game state to a special game state called a big bonus. In this big bonus, a lottery table is used that allows various small hits and RBs to be internally won with extremely high probability.

In addition, the "BAR role" is displayed on the activated pay line.
Is established and the RB wins, after 15 medals are paid out, the gaming state is switched from the general gaming state to a special gaming state called a regular bonus. In this regular bonus, only the winning line in the middle row is activated (one bet), and one special "win"
A game called a jack game aiming at only is provided. In such a jackpot game, a lottery table for internally winning the "hit" with a very high probability is used,
The above-mentioned “replay combination” is substituted for the combination corresponding to “win”.

Next, the characteristic configuration of the slot machine 1 will be described. FIG. 6 is a block diagram showing the numerical value generating circuit 17e. As shown in FIG.
e includes a clock pulse generation circuit 170, a counter circuit 171 including a plurality of LSs 161 (not shown), and a reset signal output circuit 172. Each time a clock pulse is input from the clock pulse generation circuit 170, the counter circuit 171 has, for example, 16 bits of 0 to 65.
The numerical value is counted up within the range of 536. This count-up generates a count value that increases by one. The reset signal output circuit 172 includes the counter circuit 17
The count value issued from 1 is monitored, and 6
When 5536 is detected, a reset signal is output to the counter circuit 171 to reset the count value issued from the counter circuit 171 to zero. This reset restarts the count-up from the minimum value of zero by one.

Table 2 shown below is an example of the lottery table used in the general gaming state in the conventional slot machine. In the table, the shaded area on the background is the winning area.

[Table 2]

As shown in Table 2, in the conventional slot machine, an area of 0 to 18000 including a minimum value of zero in a numerical range of 0 to 65535 is a winning area.
In addition, BB, which is a big hit, is assigned to zero where unauthorized operations are particularly easily performed. In such a configuration, the counter circuit 171 shown in FIG.
If the reset signal is forcibly output continuously, or if the output of the clock pulse generation circuit 170 is forcibly cut off at the moment of the reset by the output, the BB is internally elected forever, and a great deal of damage is caused.

Table 3 shown below is an example of the lottery table used in the slot machine 1 in the normal gaming state.

[Table 3] As shown in Table 3, in the present slot machine 1, an area of 0 to 19999 including the minimum value of zero and a maximum value of 6553
The area of 38001 to 65535 including No. 5 is a non-winning area that does not generate any “hit” (a loss is randomly selected). In such a configuration, the CPU (1
Even if an illegal operation such as continuously outputting a numerical signal of zero or 65535 is performed in 7a), a winning is not generated, and the occurrence of an illegal winning due to the illegal operation can be suppressed. And not only the minimum and maximum values,
Since the non-winning area is set from these to the area within the predetermined range, since accurate unauthorized operation was not performed,
Even when a numerical value close to the minimum value or the maximum value is continuously output, it is possible to suppress the occurrence of an improper winning due to the output.

An example in which the incorrect operation was not performed correctly is because the output of the clock pulse generation circuit 170 was cut off after a slight time lag from the output of the reset signal to the counter circuit 171 shown in FIG. , 1-200
For example, a numerical value relatively close to zero, such as the numerical value of, is output continuously. Also, based on an incorrect external circuit that detects the timing of resetting from the maximum value to zero, the output of the clock pulse generation circuit 170 was cut off immediately before this timing instead of immediately before this timing. A numerical value such as a numerical value, which is relatively close to the maximum value, is continuously output.

FIG. 7 is a schematic diagram showing each area of the lottery table shown in Table 3. As shown in the drawing, in this lottery table, an area of about 30% of the whole (27.2% for personality)
Is a winning area.

FIG. 8 is an enlarged schematic diagram showing a winning area of the lottery table shown in FIG. The winning areas include BB, R
B, watermelon small hits, bell small hits, cherry small hits, and replay small hits are provided with areas corresponding to six types of hits. About 90% of the total area is occupied by a small cherry hit area and a replay small hit area (to be precise, 89.4).

Here, as described above, even if the small replay wins, no medals are paid out, and the next game is permitted under the same medal BET conditions as before. Thus, the replay small hit is a "hit", but does not bring a substantial benefit to the player.

Further, as shown in Table 1, the number of medals paid out at the time of winning a small cherry hit is only two. With such a medal payout number, if the game at that time is made with one bet, the player has a very small profit of one medal, but if the game is made with two bets, a replay prize is won. Similarly, no profit is generated.
In addition, if a bet is made with three bets, the player may be damaged, though it is a "hit". In this way, the winning of the small cherry win may give the player a very small profit, may not bring any profit as in the case of the replay winning, or may cause damage, depending on the number of medals bet in the game. .

Therefore, the illustrated winning area is approximately 30
Although it occupies [%], the area where the player wins a win that brings a substantial benefit to the player is further 10th.
About 50%. That said, a small percentage of BBs and RBs that offer significant benefits to the player
Is included.

Now, as shown in FIG. 7, the winning area is a single area composed of continuous numerical values of 20000 to 38000, and the numerical value corresponding to this area is the numerical value generating circuit 17e. The period that is generated from is relatively long. Specifically, 0 to 6
Assuming that the time required for counting up to 5535 is one cycle, about one-third of this one cycle is a period in which a hit can occur continuously. In such a configuration, the timing of the arrival of this period is easily known to the player. As described above, even if the winning is won, the player does not necessarily have a profit, but if it becomes easier to know the timing of the above-mentioned period, it becomes easier for the BB or RB to win the retirement. It is easy to operate the start lever.

Note that, among the special game states, RB is a game state for providing a special winning prize to a player with a high probability, and RB or RB other than this winning is won. Nothing. Even if an illegal operation is performed during RB such that the generated value is misidentified as zero,
The damage caused by this is small. Therefore, during the RB, it can be said that there is no problem even if a lottery table in which the winning area starts from the minimum value (zero) or a lottery table that ends in the maximum value is used.

As an example of the illegal operation for continuously generating the minimum value and the maximum value, the operation of the so-called hardware numerical value generated by a hardware method using a counter circuit or the like has been described. However, for the reasons described below, the so-called software numerical value generated by a software method using a program is likely to be targeted at the minimum value or the maximum value similarly to the hardware numerical value.

That is, generally, a program for generating a software numerical value is stored in the ROM. If an illegal operation for falsifying this program is performed on the ROM, an error such as a runaway of the ROM is detected by security for monitoring the normal operation of the ROM, so that it is difficult to falsify the program in the ROM. However, the software numerical value that is sequentially updated by the program is RA
Since the information is stored in an insecure work such as M, an unauthorized operation that overwrites a certain numerical value on the work is possible. Such illegal operations are not limited to the minimum value and the maximum value, but include all numerical values. However, in the slot machine, the predetermined numerical value does not always correspond to the winning area. For example, in the special gaming state, since a lottery table for generating an internal winning with a higher probability than the general gaming state is used, the winning area of a certain small hit is changed from “200 to 1000” to “200 to 30”.
000 ". Thus, for example, a value of 1500 corresponds to the non-winning area in the normal gaming state, but corresponds to the winning area in the special gaming state. In this way, for the numerical value that moves between the non-winning area and the winning area, the area around the minimum value or the maximum value is constant regardless of the gaming state (in other words, the width of the area of unwinning or winning). Easy to be. Therefore, the minimum value and the maximum value are easily targeted.

[Embodiment] Next, this slot machine 1
The slot machine 1 of the embodiment in which a more characteristic configuration is added will be described. Table 4 shown below is an example showing the lottery table used in the slot machine 1 in the normal gaming state, together with the area width of each area.

[Table 4]

As shown in Table 4, in this lottery table, the winning area is composed of a plurality of discontinuous areas. Specifically, a non-winning area is set between each winning area for BB, RB, watermelon small hit, bell small hit, cherry small hit, and replay small hit. Since the winning area for the small cherry hit and the small replay hit is considerably larger than the other winning areas, the non-winning area is set between the two equal halves. In such a configuration, although one of the winnings is won in about one third of the time in one cycle, this time is discontinuous. Therefore,
During one cycle, the period that occurs continuously becomes short, and it becomes difficult for the player to know.

It is not necessary to divide the replay small hit winning area into two equal parts. This is because the player knows the timing at which the replay small hit comes, and even if the replay small hit occurs continuously, no medals are paid out and substantially no damage is caused.

[Specific Example] Next, a specific example of the slot machine 1 in which a more characteristic configuration is added to the slot machine 1 of the embodiment will be described. The slot machine 1 has table numbers 0 to 5 as lottery tables for a general gaming state.
5230 lottery tables up to 229
(17c), and the lottery table to be used is changed for each game. Specifically, the number is sequentially changed from the smallest number to the largest number, and after using the lottery table with the maximum table number 5229, the use is sequentially restarted from the lottery table with the minimum table number 0.

The details of these lottery tables are shown in Table 5 below.

[Table 5]

As shown in Table 5, the non-winning area is set between the winning areas, as in the lottery table of the embodiment, but the position of the winning area in the numerical range is set. Depends on the lottery table. Specifically, an area of 0 to 232 including the minimum value and an area of 65304 to 65535 including the maximum value are fixed as non-winning areas (fixed non-winning areas), while 233 to 6.
The area 5303 is a variation area in which the position of each area in the area fluctuates.

The variable regions are a BB winning region, an RB winning region, a watermelon small hit winning region, a bell small hit winning region,
Eight winning regions, a small cherry winning region (1), a small cherry winning region (2), a replay winning region (1), and a replay winning region (2), and between these winning regions and at the beginning of the variable region. And nine non-winning areas provided at the end.

Among these regions, the region provided at the beginning of the variable region has its region width varied in the range of 0 to 5229, and the region provided at the end of the variable region has the region width in the range of 5230 to 10449. To fluctuate. In accordance with the fluctuation of the region width of these regions, the position of another region whose region width is fixed changes.

For example, when the lottery table of table number 0 is shown together with the area width of each area, the following table 6 is obtained.

[Table 6]

In this lottery table, the region width of the last non-winning region is set to the maximum 10449, instead of the first non-winning region of the variable region.

In contrast to this lottery table, in the other lottery tables, the area width of the first non-winning area increases by one each time the table number increases by one, and the area width of the last non-winning area decreases by one. To go. As the area width changes in this manner, the start position (numerical value) of each area (excluding the first non-winning area) in the change area shifts by one each time the table number increases by one.

In the lottery table of the last table number 5229, as shown in the following Table 7, the area width of the first non-winning area in the variable area becomes the maximum 5229, and
The region width of the last non-winning region is the minimum 5230.
Therefore, the start position (numerical value) of each area excluding the first non-winning area is closest to the maximum value side.

[Table 7]

In the above configuration, even if a predetermined numerical value different from the minimum value (0) or the maximum value (65535) is used,
When an illegal operation such as providing a “hanging board” to be recognized by the PU (17a) is performed, it is possible to suppress consecutive occurrences of unreasonable winning as follows. That is, assuming that this "hanging board" generates a numerical signal of 11074, when the lottery table of table number 0 shown in Table 6 is used, the watermelon small hit is internally won in the first game. However, in the next game, since the lottery table of the table number 1 in which each area (excluding the first non-winning area) in the fluctuation area is shifted to the maximum value side is used, “outside” is internally won and a prize is won. Will not occur. After that, in the game up to 5229 times,
"Outside" wins continuously inside. Therefore, it is possible to suppress continuous occurrence of improper winning. On the other hand, when a lottery table that does not change each area is used, if a numerical signal emitted from the “hanging board” is accidentally applied to the winning area, “winning” continues to be internally won.

Although the embodiment in which the present invention is applied to a slot machine as a gaming machine has been described above, the present invention is also applicable to other gaming machines using a lottery table, such as a pachinko machine.

[0088]

According to the first, second or third aspect of the present invention, among the numerical values issued by the numerical value generating means, the occurrence of the minimum value or the maximum value which is particularly easy to perform an unauthorized operation is determined. There is an excellent effect that the occurrence of improper winning due to the illegal operation can be reduced by not allowing the means to recognize the winning.

In particular, according to the second aspect of the present invention, an illegal operation for forcing the numerical value generating means to continuously generate a predetermined numerical value different from the minimum value or the maximum value, and There is an excellent effect that it is possible to suppress continuous occurrence of improper winning due to an illegal operation for forcibly recognizing the continuous occurrence of the numerical value.

According to the third aspect of the present invention, the numerical value generating means is configured to generate a count value which is incremented by one at a predetermined timing, and the numerical value is generated based on an operation of the player. Even if the winning determination means is configured to extract the numerical value from the means, there is an excellent effect that the timing at which the winning occurs can be made difficult to be known to the player.
