DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described below with reference to the accompanying drawings. In the description, the same elements will be denoted by the same reference symbols, without redundant description.

First, referring to FIGS. 1 to 3, the first embodiment of the present invention will be described.
A mechanical slot machine according to an embodiment will be described. FIG.
2 is a front view showing an appearance of a mechanical slot machine according to the present embodiment, FIG. 2 is a block diagram showing an electric configuration applicable to the mechanical slot machine according to the present embodiment, and FIG. 3 is related to the present embodiment. FIG. 10 is a flow chart for explaining the probability adjustment in the mechanical slot machine, and FIG. 10 is a view showing the probability adjustment table.

A slot machine generally includes at least a coin slot 1, a start lever 2, a display unit 3, a switch unit 4, a reel unit 5, and a coin payout device (a coin discharge port 9, a coin payout unit 10, etc.). It is composed of.

The reel portion 5 is a physically existing first outer reel 5a, second outer reel 5b, and third outer reel 5c.
And each external reel 5a, 5b, 5c is driven by a stepping motor 5d, 5e, 5f. On the outer circumferences of the first reel 5a, the second reel 5b, and the third reel 5c, reel tapes on which a plurality of symbols are drawn are mounted, respectively. These external reels 5a, 5b, 5
c is driven by the motor drive unit 7 under the control of the microcomputer unit 6.

The player inserts one or several coins from the coin slot 1 prior to the game. The inserted coin is detected by the coin detection unit 8. In the game, valid pay lines A, B, and C are determined by the number of coins inserted.

For example, if one coin, only the pay line A is valid, and if three coins, the pay lines A, B and C are valid (see FIG. 1). Therefore, the probability of winning increases according to the number of coins. Further, the number of inserted coins is displayed as a digital number on the display unit 3. The game is started by pulling the start lever 2 or pressing the start switch, and then the first reel 5a, the second reel 5a.
The reel 5b and the third reel 5c rotate together.

The rotated reels 5a, 5b, 5c automatically stop after a certain period of time. At that time, the winning / losing of the game, the type of winning, and the amount of winning consideration are determined by the combination of symbols stopped on the valid winning line. Generally, the reels rotate fast at the beginning and cannot identify each symbol, but the rotation speed becomes slow just before the reel stops, so that each symbol can be easily identified. At the stage where each symbol can be identified, the player pays special attention to the symbol with a large payment amount. When the same symbols are lined up on the activated pay line, it usually corresponds to a win, and a fixed amount of coins are paid or credits corresponding to the coins are accumulated. When the player desires to pay out, the number of coins for the winning prize is paid to the player from the coin outlet 9. This payment control is performed under the control of the microcomputer 6 by the coin payment unit 10.
Through.

In addition to the ROM 11 and the RAM 12 as external storage elements connected to the microcomputer 6 described above, the game switch section 4, the coin detecting section 8, the coin paying section 10, the display section 3, the selecting means 13, the counting means. 14 and the comparison means 15 are connected. ROM11
Stores at least a winning table and a predetermined set value (initial setting coin insertion number, initial setting coin payment number), and the selection unit 13 is connected to a counting unit 14 for counting the number of inserted coins. . The information on the predetermined set value may be stored in the RAM or may be switched by a jumper, a dip switch, or the like.

Since a coin detection signal indicating that a coin has been inserted and a coin payment signal indicating that a coin has been paid out are sent to the counting means 14 via the microcomputer 6, based on these signals, the coin ( It is possible to count the number of coins inserted and coins paid out. The counting means 14 has at least two functions. The first function is to count the number of coins inserted by a player into the slot machine from the time when the game installation business starts, and the second function is to calculate the number of coins paid out to the player when the game installation business starts. It is a function to count from time. The microcomputer 6 provides information regarding the number of inserted coins and information regarding the number of payout coins. The counting means 14
The number of coins is counted based on these pieces of information, and the counting result is temporarily stored in the internal memory. Also, the counting means 1
The comparing means 15 for comparing the count value and the set value is connected to 4, and the comparing means 15 is sent from the counting means 14 two kinds of information (total number of inserted coins and total number of payout coins).

The comparison means 15 has at least two functions. The first function is the total number of coins inserted by the player and P /
A second function is a function of comparing with a default value for rank-up that increases the probability that a symbol table with a high O will be selected. The second function is the total number of coins paid out to the player and the symbol table with a low P / O. It is a function to compare with the initial setting value for rank down which increases the probability of selection. The information regarding the number of inserted coins and the total number of payout coins are supplied from the counting means 14, and the rank-up initial setting value and the rank-down initial setting value are supplied from the ROM 11. The probability adjusting means 16 is further connected to the comparing means 15, and the result of comparison based on the above information is the probability adjusting means 16
Sent to

The probability adjusting means 16 has at least two functions. The first function is to increase the probability that a symbol table with high P / O will be selected based on the result of comparison between the total number of coins inserted by the player and the rank-up initial setting value.
The second function is a function that increases the probability that a symbol table with a low P / O will be selected based on the result of comparison between the total number of coins paid out to the player and the rank down initial setting value. That is, based on the information sent from the comparison means 15, a plurality of symbol tables 18 having different payout rates are provided.
a, 18b, 18c, 18d, 18e, 18f, 18
Probability for weighting is given to g and 18h. Note that the method disclosed in U.S. Pat. No. 4,448,419 (Telnaes) may be used as the method of assigning the weighting probability. Further, the probability adjusting means 16 has a selecting means 1
3 is connected so that information on probability adjustment can be sent to the selection means 13. Furthermore, the selection means 13
A random number generating means 17 is connected to and the information about the random number is sent. The random number generation means 17 may be composed of software of a microcomputer.

The selecting means 13 is the microcomputer 6
Under the control of, the information sent from the probability adjusting means 16 is referred to, and based on the random number sent from the random number generating means 17,
A plurality of symbol tables 18a, 18b, 18c, 18
One symbol table is selected from d, 18e, 18f, 18g, and 18h. The symbol table selected by the selection means 13 will be applied to the current game. In the game, the symbols to be stopped are selected for each reel based on the random numbers generated by the random number generation means 17, similarly to the ordinary slot machine. Whether a combination of symbols selected by random numbers constitutes a prize, the type of prize, the number of prizes, and the like are determined based on a prize table stored in the ROM 11.

In this winning table, all symbol combinations, winning rankings, and the number of payout coins are defined. The microcomputer 6 determines whether or not to form a prize based on this prize table. It should be noted that the determination as to whether or not the prize is won is performed at any time by the microcomputer after the symbols to be stopped on each reel are determined.

Further, the slot machine according to the first embodiment is provided with a plurality of symbol tables composed of the first reel, the second reel and the third reel corresponding to the physically existing external reels 5a, 5b and 5c. Contains an internal reel included. In this embodiment, a plurality of symbol tables 18a, 1a
8b, 18c, 18d, 18e, 18f, 18g, 18
An inner reel 18 having h is included. The internal reel 18 including these plural symbol tables is stored in the internal reel storage means 19 controlled by the microcomputer. A plurality of symbol tables 18a, 18b,
18c, 18d, 18e, 18f, 18g and 18h are
Different refund rates (eg 85%, 90%, 100%,
105%, 110%, 120%, ...), the number and types of symbols included in the internal reels are different. In this embodiment, the number of symbols is 5 on the outer reel.
There are 22 a, 5b, and 5c each, and 32 internal reels each, but the first reel that constitutes the internal reel,
The second reel and the third reel do not have to have the same number of all symbols.

For example, the total number of symbol combinations may match the total number of types of random numbers that the random number generating means 17 can generate. As a specific example, when a 13-bit register is used for the random number generation means 17, the random numbers that can be generated are 8192.
Kind. In this case, there are 16 first reels, 16 second reels, and 32 third reels, and the total number of symbol combinations can be 8192. With this configuration, since all types of random numbers can be associated with one symbol, it is possible to select symbols without bias.

The above-mentioned reels 5a, 5b, 5c are driven by a motor drive section 7 under the control of the microcomputer 6. For the stop position of each reel, one symbol is specified for each reel based on a random number by referring to the selected symbol table. The first reel 5a is controlled by the microcomputer 6 so that the symbol of the external reel corresponding to the symbol of the specified symbol table stops at the display window. The stop position of the first reel 5a is determined, for example, when a coin is inserted, and the stop position of the second reel 5b and the third reel 5c is, for example, the start switch of the game switch unit 4 is pressed or the start lever 2 is pulled. Will be decided when First reel 5a,
When the second reel 5b and the third reel 5c are stopped, the respective first reels 5 along the respective pay lines A, B, C.
The symbols on a, the second reel 5b, and the third reel 5c are specified.

When a winning combination is realized on any valid winning line, coins of the number corresponding to the winning are paid out from the coin outlet 11. At the same time, the display unit 3
The number of coins to be paid out is displayed together with the number of coins inserted, and one game ends. Data relating to the number of inserted coins and the number of paid-out coins are sent to the counting means 14 through the microcomputer 6.

Next, a playing method and a probability adjusting method of the slot machine according to the first embodiment will be described with reference to FIGS. 3 and 10.

When the game starts, counting of inserted coins is started. For example, 3 games per 10 games
Assuming that coins are inserted one by one, the counting means 14 adds up a total of 30 coins. Simultaneously with the start of the game, the initial set value (No) of coins is set (step 101).

In the first embodiment, the initial table is the symbol table applied in the immediately preceding game.
The initial setting value (No) is the number of inserted coins required for rank up, and is set to, for example, 50 coins.

Each time the player inserts a coin, the counting means 14 counts the number of inserted coins, and the counted insertion number (Nx) and the initial set value (No) are compared by the comparison means (15). (Step 102). Input number (Nx
) Is equal to or greater than the initial setting value (No), the probability is increased so as to select a symbol table having a higher payout rate (P / O) by raising the rank according to the difference (step 103). ). Here, in order to simplify the following description, according to the difference between the number of input (Nx) and the initial setting value (No), the rank is increased by I rank, that is, the number of input exceeds (50 × I). Suppose.

In the first embodiment, eight types of P / O are used.
(85%, 90%, 100%, 105%, 110%, 1
Symbol table (18a, 18b, 18c, 18d, 18e, 18) having 20%, 150%, 200%)
f, 18g, 18h). The simplest example of the probability adjustment table for these symbol tables is shown in FIG. That is, as the number of actually inserted coins increases, the selection probability of the symbol table having the highest P / O increases from 2 times to 8 times, and conversely,
The lowest P /
This is an example in which the selection probability of the symbol table having O increases from 2 times to 8 times.

For example, if the initial table is P / O (100
%), When the initial set value (No) is 50 and the number of inserted sheets does not reach 50, the initial table is applied as it is, but rank up (R / U) initial set value (No) When the inserted coin reaches, the rank is increased by 1 and the probability that the symbol table with the highest P / O (200%) is selected is doubled, while the lowest P / O (8
The probability that the symbol table of 5%) is selected is “0” (see FIG. 10). In this way, “probability weighting” is performed according to the number of inserted sheets. Such probability adjustment is performed by the probability adjusting means 16.

The increased rank is applied to the current game, and excess coins exceeding the number of coins required to reach that rank are carried over to the next game (step 104). For example, in the above example, Nx = 12
If it is 6, the rank is increased by 2 steps, and the fraction not used for increasing the rank is carried over to the next game. Generally, I · No <Nx <(I + 1) ·
When represented as No, the rank applied to the current game is increased by I rank, and (Nx-I · No) is assigned to Nx of the next game.

Next, on the basis of the probability-weighted symbol table, in order to select one symbol table from these, a random number is generated using the random number generating means 17 (step 105) and one symbol table is generated. Select a table and use a new random number for each reel 5a, 5b,
5c determines the symbols to be stopped on the pay line (A, B, C) (step 106).

As described above, since the stop symbol of the first reel 5a is determined when the coin is inserted, the probability adjustment and the symbol table determination for the internal reel 18 described above should be performed when the previous game ends. Is desirable. Alternatively, a random number for symbols is generated at the time of coin insertion, and then the probability of the symbol table is adjusted and the symbol table is determined while the reels are rotating. Alternatively, the symbol corresponding to the symbol random number may be fixed.

When the symbols to be stopped are determined in the selected symbol table, the reels 5a, 5b, 5c
Is stopped and the symbol is displayed on the pay line (step 107).

The outer reels 5a, 5b, 5c are provided with projections 5j, 5k, 5l on their side surfaces, and detection devices (eg, light emitting element and light receiving element) 5g, 5h, 5i are provided in the vicinity of the orbit through which the projections 5j, 5k, 5l pass. Since they are arranged, the reference positions of the external reels 5a, 5b, 5c can be reliably detected.
Referring to this reference position, the stepping motors 5d, 5
The stop positions of the reels are controlled by e and 5f and the motor drive unit 7, and the rotation of the external reels 5a, 5b, and 5c is stopped.

Next, it is determined whether or not the combination of the stop symbols stopped on the activated pay line constitutes one of the wins (step 108). This judgment is made by referring to the winning table and referring to the microcomputer 6
Do. It should be noted that the determination of the winning may be performed before the rotation of the reel is stopped as long as the stop symbol is confirmed.

As a result of the winning determination, when the symbol combination corresponds to the winning, the coins defined in the winning table are paid out (step 109).

Coins are paid out under the control of the microcomputer 6 in principle through the coin payer 10. However, "BET" in game switch section 4
When the game is played by pressing the switch, coins are not paid, and instead, the same number as the number of payouts is displayed as a credit on "CREDIT" of the display device 3. This "C
The number displayed as "REDIT" is treated in the same way as an actual coin, and if you press the "BET" switch once, you will have inserted one coin, and the credit displayed in "CREDIT" on display 3 The number is decremented by 1. When the number of coins inserted in the game exceeds the maximum number of coins inserted, "MAX
When the BET "switch is pressed, the maximum number of inserted coins in one game has been inserted, and the number of credits on the display unit 3 is also reduced by the maximum number of inserted coins. The" PAY OUT "switch of the game switch unit 4 is turned on. When pressed, coins equal to the number displayed on the display unit 3 are paid out from the coin outlet 9.

When paying out the number of winning prizes, the number of refunds Px is compared with the probability adjustment table (FIG. 10), and rank down (R) required to lower the current rank is performed.
/ D) When the number of sheets (Px) more than the initial setting value (Pi) is paid out, the probability of selecting a lower P / O symbol table is increased according to the difference between (Pi) and (Px). (Step 111).

The lowered rank is applied to the next game, and the number of excess coins exceeding the number of coins required to reach that rank is carried over to the next game (step 112). For example, when Pi = 45 and Px = 100, the rank is lowered by two steps, and the fraction (10) not used for lowering the rank is carried over to the next game. Generally, J · Pi <Px <(J + 1) ·
When represented as Pi, the rank is lowered by J ranks, and (Px-J.Pi) is assigned to Px of the next game.

The R / D initial set value (Pi) is preferably set together with the R / U initial set value (No) at the start of the game, but after the payout number is fixed and the next game is started. It may be set before the start.

The mechanical slot machine has been described in the first embodiment, but as described in the second embodiment,
This may be applied to a video type slot machine.

Next, a video type slot machine according to a second embodiment of the present invention will be described with reference to FIGS.

FIG. 4 is a block diagram showing an electric circuit configuration applicable to the video slot machine according to this embodiment, and FIG.
Is a flow chart for explaining probability adjustment in the video type slot machine.

The difference from the first embodiment is that the mechanical reel 5
a, 5b, 5c, stepping motors 5d, 5e, 5f
CRT 20 and CR without the motor drive unit 7
The point is that the T control unit 21 is provided.

Start lever 2, game switch section 4, microcomputer 6, coin detecting section 8, coin paying section 10, ROM 11, RAM 1 which are other components.
2, the selecting means 13, the counting means 14, the comparing means 15, the probability adjusting means 16, the random number generating means 17, and the internal reel storing means 19 are substantially the same, and therefore their explanations are omitted. The CRT 20 and the CRT controller 21 can use the structure of a conventional video slot machine.

Next, a playing method and a probability adjusting method in the video type slot machine according to this embodiment will be described with reference to FIGS.

When the game starts, counting of inserted coins is started. For example, 3 games per 10 games
Assuming that coins are inserted one by one, the counting means 14 adds up a total of 30 coins. Simultaneously with the start of the game, the initial set value (No) of coins is set (step 201).

Similar to the first embodiment, the initial table is the symbol table applied in the immediately preceding game.
The initial setting value (No) is the number of inserted coins required for rank up, and is set to, for example, 50 coins.

Each time the player inserts coins, the counting means 14 counts the number of inserted coins, and the counted insertion number (Nx) and the initial setting value (No) are compared by the comparison means (15). (Step 202). Input number (Nx
) Is greater than or equal to the default value (No), the probability is increased so that the symbol table having a higher payout rate (P / O) is selected with a higher probability by raising the rank according to the difference. (Step 20)
3). Here, in order to simplify the following description, I is set according to the difference between the number of input sheets (Nx) and the initial setting value (No).
It is assumed that the rank is upgraded, that is, the number of sheets exceeds (50 × I).

For example, if the initial table is P / O (100
%), When the initial set value (No) is 50 and the number of inserted sheets does not reach 50, the initial table is applied as it is, but rank up (R / U) initial set value (No) When the inserted coin reaches, the rank is increased by 1 and the probability that the symbol table with the highest P / O (200%) is selected is doubled, while the lowest P / O (8
The probability that the symbol table of 5%) is selected is “0” (see FIG. 10). In this way, “probability weighting” is performed according to the number of inserted sheets. Such probability adjustment is performed by the probability adjusting means 16.

The increased rank is applied to the current game, and excess coins exceeding the number of coins required to reach that rank are carried over to the next game (step 204). For example, in the above example, Nx = 126
If so, the rank is increased by two steps, and the fraction not used for increasing the rank is carried over to the next game. Generally, I · No <Nx <(I + 1) · N
When represented as o, the rank is increased by I rank, and (Nx-I · No) is assigned to Nx of the next game.

Next, in order to select one symbol table from these based on the probability weighted symbol table, a random number is generated using the random number generating means 17 (step 205) and one symbol table is generated. A table is selected and a new random number is used to determine the symbol that each reel should stop on the pay line (A, B, C) (step 206). When the symbols to be stopped are determined in the selected symbol table, the rotation (scrolling) of the first reel, the second reel, and the third reel is stopped, and the stopped symbols are displayed on the pay line (step 207).

Next, it is determined whether or not the combination of the stop symbols stopped on the activated pay line constitutes any prize (step 208). This judgment is made by referring to the winning table and referring to the microcomputer 6
Do.

The determination of the winning may be performed before the reel scrolling is stopped as long as the stop symbol is confirmed. As a result of the winning determination, when the symbol combination corresponds to the winning, the coins defined in the winning table are paid out (step 209). The payout of coins is performed under the control of the microcomputer 6 in principle through the coin payout unit 10.

When payout of the number of winning prizes is made, the number of payouts Px is compared with the probability adjustment table (FIG. 10), and the rank down (R
/ D) When the number (Px) of sheets equal to or larger than the initial setting value (Pi) is paid out (step 210), the symbol table of lower P / O is further improved according to the difference between (Pi) and (Px). The probability of selecting with a high probability is increased (step 2
11).

The lowered rank is applied to the next game, and the excess number of coins exceeding the number of coins required to reach that rank is carried over to the next game (step 212). For example, when Pi = 45 and Px = 100, the rank is lowered by two steps, and the fraction (10) not used for lowering the rank is carried over to the next game. Generally, J · Pi <Px <(J + 1) ·
When represented as Pi, the rank is lowered by J ranks, and (Px-J.Pi) is assigned to Px of the next game.

Next, a game machine to which the present invention is applied to a card game will be described as a third embodiment and a fourth embodiment.

First, with reference to FIGS. 6 and 7, a poker game device according to the third embodiment will be described.

FIG. 6 is a block diagram showing a circuit structure applicable to the poker game apparatus according to the third embodiment, and FIG.
6 is a flowchart for explaining probability adjustment in the poker game device according to the third embodiment.

The basic structure is the same as that of the second embodiment. However, the game program stored in the ROM 11 is for a poker game, the internal card storage means 19 stores an internal card 22 composed of a plurality of card tables, and the CRT control unit 21 further executes the card game. Control the CRT 20 to achieve. Since these are the same as the conventional structure, detailed description thereof will be omitted, and hereinafter, the probability adjustment processing will be mainly described.

When the game starts, counting of inserted coins is started. For example, 3 games per 10 games
Assuming that coins are inserted one by one, the counting means 14 adds up a total of 30 coins. Simultaneously with the start of the game, the initial set value (No) of coins is set (step 301).

Similar to the first embodiment, the initial table is the card table applied in the immediately preceding game. The initial setting value (No) is the number of inserted coins required for rank up, and is set to, for example, 50 coins.

Each time the player inserts coins, the counting means 14 counts the number of inserted coins, and the counted insertion number (Nx) and the initial set value (No) are compared by the comparison means (15). (Step 302). Input number (Nx
) Is greater than or equal to the default value (No), the probability is increased by increasing the rank according to the difference so that a card table having a higher payout rate (P / O) is selected with higher probability. (Step 30)
3). Here, in order to simplify the following description, I is set according to the difference between the number of input sheets (Nx) and the initial setting value (No).
It is assumed that the rank is upgraded, that is, the number of sheets exceeds (50 × I).

For example, if the initial table is P / O (100
%), When the initial set value (No) is 50 and the number of inserted sheets does not reach 50, the initial table is applied as it is, but rank up (R / U) initial set value (No) When the inserted coin reaches 1, the probability of selecting a card table with a higher P / O (200%) is doubled, while the lowest P / O (85%).
%) The probability that the card table will be selected is "0" (see FIG. 10). In this way, “probability weighting” is performed according to the number of inserted sheets. Such probability adjustment is performed by the probability adjusting means 16.

The increased rank is applied to the current game, and excess coins exceeding the number of coins required to reach that rank are carried over to the next game (step 304). For example, in the above example, Nx = 126
If so, the rank is increased by two steps, and the fraction not used for increasing the rank is carried over to the next game. Generally, I · No <Nx <(I + 1) · N
When represented as o, the rank is increased by I rank, and (Nx-I · No) is assigned to Nx of the next game.

Next, one of these card tables must be selected based on the weighted card tables. Therefore, a random number is generated using the random number generation means 17 (step 305) and one card table is selected. When the card table is selected, the random number generating means 17 then generates a new random number for each of the five cards and determines the card to be displayed on the CRT 20 (step 306). As for the card, the surface (design) of the card is displayed on the CRT 20 (step 30)
7). The player exchanges unnecessary cards of a predetermined number or less by button operation or the like, continues the game, and makes a prize determination according to the game result (step 308). This winning determination is performed by the microcomputer 6 with reference to the winning table. The winning determination may be made after the displayed card is confirmed, as described above, and the card is CR
It may be performed before displaying at T20.

After the judgment, when the prize is won, the coins of the amount defined in the prize table are paid out (step 309). The payout of coins is performed through the coin payout unit 10 under the control of the microcomputer 6.

When payout of the number of winning prizes is made, the number of payouts Px is compared with the probability adjustment table (FIG. 10), and rank down (R) required for lowering the current rank is performed.
/ D) When the number (Px) of cards equal to or greater than the initial setting value (Pi) is paid out (step 310), the card table of lower P / O is further selected according to the difference between (Pi) and (Px) The probability of selection is increased with a high probability (step 31).
1).

The lowered rank is applied to the next game, and the number of excess coins exceeding the number of coins required to reach that rank is carried over to the next game (step 312). For example, when Pi = 45 and Px = 100, the rank is lowered by two steps, and the fraction (10) not used for lowering the rank is carried over to the next game. Generally, J · Pi <Px <(J + 1) ·
When represented as Pi, the rank is lowered by J ranks, and (Px-J.Pi) is assigned to Px of the next game.

Next, a blackjack game device according to the fourth embodiment will be described with reference to FIGS.

FIG. 8 is a block diagram showing a circuit configuration applicable to the blackjack game device according to the fourth embodiment, and FIG. 9 illustrates probability adjustment in the blackjack game device according to the fourth embodiment. It is a flowchart for.

Compared to the third embodiment, the basic structure is the same. However, a program for blackjack game is stored in the ROM 11, and the CRT control unit 21 uses C to implement the blackjack game.
Control the RT20. Since these points are the same as the conventional structure, detailed description will be omitted.

When the game starts, counting of inserted coins is started. For example, 3 games per 10 games
Assuming that coins are inserted one by one, the counting means 14 adds up a total of 30 coins. Simultaneously with the start of the game, the initial set value (No) of coins is set (step 401).

Similar to the first embodiment, the initial table is the card table applied in the immediately preceding game. The initial setting value (No) is the number of inserted coins required for rank up, and is set to, for example, 50 coins.

Each time the player inserts a coin, the counting means 14 counts the number of inserted coins, and the counted insertion number (Nx) and the initial setting value (No) are compared by the comparison means (15). (Step 402). Input number (Nx
) Is greater than or equal to the default value (No), the probability is increased by increasing the rank according to the difference so that a card table having a higher payout rate (P / O) is selected with higher probability. (Step 40)
3). Here, in order to simplify the following description, I is set according to the difference between the number of input sheets (Nx) and the initial setting value (No).
It is assumed that the rank is upgraded, that is, the number of sheets exceeds (50 × I).

For example, if the initial table is P / O (100
%), When the initial set value (No) is 50 and the number of inserted sheets does not reach 50, the initial table is applied as it is, but rank up (R / U) initial set value (No) When the inserted coin reaches 1, the probability of selecting a card table with a higher P / O (200%) is doubled, while the lowest P / O (85%).
%) The probability that the card table will be selected is "0" (see FIG. 10). In this way, “probability weighting” is performed according to the number of inserted sheets. Such probability adjustment is performed by the probability adjusting means 16.

The raised rank is applied to the current game, and excess coins exceeding the number of coins required to reach that rank are carried over to the next game (step 404). For example, in the above example, Nx = 126
If so, the rank is increased by two steps, and the fraction not used for increasing the rank is carried over to the next game. Generally, I · No <Nx <(I + 1) · N
When represented as o, the rank is increased by I rank, and (Nx-I · No) is assigned to Nx of the next game.

Next, one of these card tables must be selected based on the weighted card tables. Therefore, a random number is generated using the random number generation means 17 (step 405) and one card table is selected. When the card table is selected, the random number generating means 17 then generates new random numbers for each of the first four cards (parent: 2 cards, player: 2 cards) and is displayed on the CRT 20. The card is determined (step 406). As for the card, the surface (design) of the card is displayed on the CRT 20 (step 407). The player continues to play the game by, for example, operating a button to indicate whether or not more cards are needed. Then, a winning determination is made according to the game result (step 408). For this winning determination, the microcomputer 6 is referred to by referring to the winning table.
Do. As described above, the winning determination may be made after the displayed card is confirmed, and the card is displayed on the CRT.
It may be performed before displaying on 20.

After the judgment, when the winning is judged, the coins of the amount specified in the winning table are paid out (step 409). The payout of coins is performed through the coin payout unit 10 under the control of the microcomputer 6.

When payout of the number of winning prizes is made, the number of payouts Px is compared with the probability adjustment table (FIG. 10), and rank down (R) required for lowering the current rank is performed.
/ D) When the number (Px) of cards equal to or greater than the initial setting value (Pi) is paid out (step 410), the card table of lower P / O is further selected according to the difference between (Pi) and (Px). The probability of selecting with a high probability is increased (step 41).
1).

The lowered rank is applied to the next game, and the number of excess coins exceeding the number of coins required to reach that rank is carried over to the next game (step 412). For example, when Pi = 45 and Px = 100, the rank is lowered by two steps, and the fraction (10) not used for lowering the rank is carried over to the next game. Generally, J · Pi <Px <(J + 1) ·
When represented as Pi, the rank is lowered by J ranks, and (Px-J.Pi) is assigned to Px of the next game.

As described above, in Examples 1 to 4, the symbol table or the card table having a high P / O is applied according to the number of inserted coins, and the probability is weighted.

In the above-mentioned embodiment, the selection probability of the symbol table or the card table is adjusted depending on the number of payouts. For example, when the payout number exceeds a certain amount, the probability of selecting a low P / O is increased stepwise. In this case, the number of sheets required for rank down need not be the same as the number of sheets required for rank up.

For example, the transition to the card table having a high P / O or the selection probability of the card table depending on the number of inserted sheets is performed at intervals of 50 cards (100, 150, 200, 25).
0. . . ), The transfer of the selection probability to the card table or the card table having a low P / O by payout may be performed at intervals of 40 cards.
