Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a slot machine, and more particularly to a slot machine that has a function of displaying to players the occurrence of winnings and losses in games that have already been played. It is.

[Conventional technology]

In general, slot machines are set so that winnings with a high payout rate have a low probability of occurring, and losing has the highest probability of occurring. Therefore, for example, if a jackpot where the combination of symbols on the 3 reels is r7, 7, 7° has appeared several times in a game that has already been played, the probability of a jackpot is lower. It can be said that it is in a state of being.

Against this background, slot machines have been proposed that have a function of displaying the number of winnings, particularly the number of jackpots. According to this, when a player is about to start a game, he or she can select a machine based on how many jackpots have been won in the past, and the winning rate is better than selecting a machine randomly. can be increased.

[Problem to be solved by the invention]

However, in the case of the conventional slot machine mentioned above,
Since it simply displays the number of winnings, regardless of the number of games played or the number of losses, it is necessary to judge whether the probability is that winnings are likely to occur. I couldn't.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a slot machine in which it is possible to easily identify whether or not it is easy to win a prize based on probability.

[Means to solve the problem]

In order to achieve the above object, the present invention not only displays the number of wins that have occurred in the past, but also counts the number of times that each type of win has occurred, as well as the number of times that losses have occurred, and displays the number of times that these have occurred. Alternatively, the incidence rate may be displayed for each type.

Furthermore, if the probability of winning a prize is low based on the number of wins or losses in games that have already been played, clear the data on the number of wins and losses up to that point. This allows the game to be easily started from the initial state.

[Effect]

Players can see the number of wins and losses that have already occurred, as well as the rate of occurrence of these, so they can use this information to judge whether or not there is a tendency to win at that time, and to select machines. You will be able to make use of it.

In addition, if a large number of wins have occurred in the games that have already been played, and it is judged that the probability of winning is low, the counting means for counting the number of wins and losses will be initialized. It is also possible to reset the state and restart the game anew without being affected by past data.

Hereinafter, the slot machine of the present invention will be explained with reference to the drawings.

[Example] In FIG. 1 showing the appearance of the slot machine of the present invention,
The slot machine 2 is provided with a front door 3 that can be opened and closed. This front door 3 has a start lever 4. 5. Reset button for resetting the display, which will be described later. A medal slot 6 is provided. A front panel 8 is fitted above the reset button 5, and on the back side of the front panel 8 are arranged three reels 9 to 11 that rotate in unison when the start lever 4 is operated. In addition, each reel 9~
11 rotates at a steady speed for a certain period of time, then its rotation is stopped by a well-known auto-stop.

Each reel 9 to 11 has various symbols arranged around its outer periphery, such as "Bell", "Cherry J, R7", "rBAR", etc., and these symbols are arranged in three windows formed on the front panel 8. 12 to 14 can be observed. A plurality of winning lines 15 are drawn across these windows 12 to 14, and the number of activated winning lines 15 increases or decreases depending on the number of medals inserted.

For example, r7,7 on this activated winning line 15.
,7J, rBAR,BAR,BAR,, ``Bell, bell, bell'', ``Cherry, cherry.

If the same symbols line up like "Cherry", you will win a prize.
The number of medals corresponding to each winning prize is paid out to a tray 16 provided at the bottom of the slot machine 2. A display 17 is attached to the upper part of the slot machine 2 to display the winnings entered after the start of the game and the remaining percentage of losses.

The survival rate is calculated based on the number of wins and losses that are assumed to occur in 10,000 games, and is displayed as a percentage in a bar graph.

In this embodiment, the remaining rate of each win and loss is displayed, but the occurrence rate or number of occurrences of each win and loss may be displayed. In addition, in the above embodiment, the remaining rate of each winning and losing rate was displayed as a bar graph, but in Figures 4 and 5.
As shown in the figure, it may be displayed in a pie chart or 7-segment digital format.

FIG. 2 shows the electrical configuration of the slot machine 2. As shown in FIG. The start lever 4 is connected to a system controller 20 that controls the slot machine 2 via a start signal generator 4a. The system controller 20 is connected to a medal input sensor 6a attached to the medal input slot 6 for detecting medals, and a medal dispenser 22 via a driver 21, respectively. The start signal generator 4a outputs a start signal at the timing of operating the start lever 4, and the medal insertion sensor 6a outputs a random number generation signal at the timing of medal detection.

Further, a motor control circuit 23 that is activated by the start signal is connected to the system controller 20. Pulse motors 25-27 for rotating the reels 9-11 are connected to this motor control circuit 23 via drivers 28-30.

The motor control circuit 23 also includes photo sensors 32 to 3.
4 is connected, and these photosensors 32 to 34 detect the light shielding pieces 9a to lla provided on each reel 9 to 11, and detect passage of the reference position every time each reel 9 to 11 rotates once. .

The motor control circuit 23 performs stop control of each reel 9-11 based on drive pulses output to each pulse motor 25-27 and reference positions detected by the photosensors 32-34.

A random number orderer 35 is connected to the system controller 20, and this random number generator 35 generates random numbers from 0 to 9999 in response to a random number generation signal.

A sampling circuit 36 that performs sampling in response to a start signal is connected to this random number generator 35, and a random number "N" sampled by this sampling circuit 36 is connected to the random number generator 35.
is sent to the system controller 2°. The system controller 20 has a combination of symbols corresponding to each number from 0 to 9999, for example, 0 to 9 are r7, 7, 7J, 1
0 to 49 are rBAR, BAR, BARJ, 50 to 24
9 is "Bell, Bell, Bell 4. 250-1499 is "Cherry, Cherry, Cherry J, 1500-9999 is [
A winning probability table 37 in which combinations of different symbols are recorded and a payout table 38 in which the number of payout medals corresponds to each symbol combination are connected to each other.

When the random number "N" is input, this success probability table 37 outputs the corresponding signals such as symbol signal "7", symbol signal rBARJ, symbol signal "Bell", symbol signal "Cherry", and symbol signal "Lose". Output. These symbol signals are sent to the system controller 20
are sent to a counting section 39 consisting of five counters 39a to 39e, and for each symbol signal, for example, the symbol signal "7" is "FA", the symbol signal rBARJ is "BJ", and the symbol signal "Bell" is "C". , the symbol signal "cherry" is "DJ", and the symbol signal "lost" is rE,
Each of the counters 39a to 39e counts. These five counters 39a to 39e are each reset to "0" by a reset signal output from the reset signal generator 5a to the system controller 20. Also,
In the payout table 38, when the symbol signal is input, each signal corresponding to the symbol signal, for example, the payout signal r500J for the symbol signal "7", the payout signal rloO' for the symbol signal rBARJ, the payout signal rl5J for the symbol signal "Bell", the symbol When the signal is “cherry”, the payout signal is “3”, and when the symbol signal is “lost”, the payout signal is “0”.
” are output respectively.

The system controller 20 also includes the display 17.
A display control circuit 40 is connected to the display control circuit 40 for controlling the driving of the display control circuit 40 .

This display control circuit 40 includes the five counters 39a to 3.
The lighting percentage of each bar graph is calculated from "A" to "E" of 9e, and each bar graph on the display 17 is turned on via the LCD driver 43 based on the calculation result. Therefore, when the reset button 5 is operated, each bar graph on the display 17 is turned on 100% by the display control circuit 40.

The operation of the slot machine 2 constructed in this way will be explained with reference to FIG. 3. When a medal is inserted through the medal slot 6, the medal input sensor 6a is activated, the random number generator 35 is driven, and the start lever 4. The reset button 5 can now be operated. Reset button 5
When the above operation is performed, a reset signal is output from the reset signal generator 5a to the system controller 20. As a result, the system controller 20 returns the slot machine 2 to the initial state when the power was turned on. By returning to the initial state, each of the five counters 39a to 39e is r
QJ is reset, and each bar graph on the display 17 is lit 100% by the display control circuit 40.

After that, when the start lever 4 is operated, a start signal is transmitted to the motor control circuit 23. It is output to the sampling circuit 36. The motor control circuit 23 drives each pulse motor 25-27 via drivers 28-30 to rotate each reel 9-11. The sampling circuit 36 generates a random number r generated by the random number generator 35.
Don't be selective (sample).

For example, when the random number "N" is "2", a symbol signal "7" is determined in the winning probability table 37 and a payout signal "500 coins" is determined in the payout table, and these are output to the system controller 20.

The system controller 20 sends this symbol signal "7" to the motor control circuit 23. The signals are sent to the counting section 39, respectively.

In the counting section 39, a counter 39a is incremented by "1". The motor control circuit 23 controls the drive of each of the pulse motors 25 to 27 based on the symbol signal "7", stops the drive, and stops the rotation of each of the reels 9 to 11. As a result, symbol combination r7,7°7'' is completed on the activated pay line 15. When each reel 9 to 11 stops in this manner, a control completion signal is output from the motor control circuit 23 to the system controller 20.

This causes the system controller 20 to
The medal dispenser 22 is driven via the receiver, and the receiver dispenses 500 medals onto the tray 16.

At the timing when the control completion signal is output to the system controller 20, the display control circuit 40 starts the counter 39.
A=1 read from a is expressed as: (100-100・A/
10) and perform the calculation. This calculation result is displayed on the LCD
It is displayed on the display 17 via the driver 43. As a result, the lighting ratio of the bar graph "7" changes from 100% in FIG. 3(W) to 90% in FIG. 3(X). In this way, the first game ends.

Thereafter, when the start lever 4 is operated without operating the reset button 5, the second game is started. The motor control circuit 23 rotates each reel 9 to 11, and the sampling circuit 36 samples the random number "N" for the second time. When the random number “N” is, for example, 9000, a symbol signal “Lose” is sent from the winning probability table 37 and a payout signal “0” is sent from the payout table 38 to the system controller 20. The system controller 20 sends a symbol signal "lost" to the motor control circuit 23 and the counting section 39.

In the counting section 39, a counter 39e is incremented by "1". The motor control circuit 23 stops driving each pulse motor 25 to 27, and the winning line 15 with the same symbol activated
Stop each reel from 9 to 110 rotations so that there are no 3 reels lined up. Note that at this time, the system controller 20
Since the payout signal ``0'' is input to , the medal payout device 22 is not driven.

At the timing when the control completion signal is output to the system controller 20, the display control circuit 40 converts E=1 read from the counter 39e into the formula: (100-100-E/85
00) and perform the calculation.The result of this calculation is displayed on the LCD.
It is displayed on the display 17 via the driver 43.

Hereinafter, each reel 9 is controlled via the motor control circuit 23.
Omitting the stop operations in steps 1 to 11, a description will be given of how the lighting ratio of the bar graph "7" shown in FIG. 3 is reduced by 10%. When the game is repeated without operating the reset button 5 and the second symbol signal r7J is sent from the winning probability table 37 to the counting section 39 via the system controller 20, the counter 39a is incremented by r11 and the value "A" is ” becomes “2”. As a result, the display control circuit 40 calculates A=2 using the formula: (100-100°・A/1
0) and perform the calculation. This calculation result "80" is displayed on the display 17 via the LCD driver 43. At this time, the lighting ratio of the bar graph "7" is shown in Figure 3 (Y
), it becomes 80%.

Furthermore, when the game is repeated and the third symbol signal "7" is output to the counting section 39, the counter 39a becomes "1".
” is incremented, and “A” becomes “3”. After this, the display control circuit 40 calculates A=3 using the formula: (100-100・A/10)
Substitute into and perform the calculation. This calculation result "70" is sent to the display 1 via the LCD driver 43 in the display control circuit 40.
7 is displayed. The lighting ratio of the bar graph "7" is 70% as shown in FIG. 3 (Z).

In the slot machine 2 described above, the player can judge the probability of a "big hit" while looking at the display 17. For example, in the display 17 shown in FIGS. 1 and 2, the remaining rates of "jackpot" and "buzz" are 30% and 70%, so it can be seen that "jackpot" is unlikely to occur in this slot machine 2. . In such a case, the slot machine 2 can be returned to its initial state by operating the reset button 5, thereby increasing the player's interest.

Note that in the sampling circuit 36 of the slot machine 2, the random numbers from 0 to 9999 generated by the random number generator 35 are sampled without selection. A setting condition is provided so that the sampled random numbers are not sampled again until all the random numbers are sampled, and this setting condition can be canceled by the reset signal. You can also change the probability of a “jackpot” occurring.

Further, although the slot machine of the present invention has been explained using a type of slot machine that stops the reels with an auto-stop, the slot machine of the present invention can also be applied to a slot machine with a stop button or a video type slot machine. can.

〔Effect of the invention〕

As explained in detail above, in the slot machine according to claim (1), the number of wins or losses that occur in each game is counted for each type, and the number of occurrences or the rate of occurrence is calculated. Since the game is displayed, the player can select a slot machine in which a jackpot will occur with a high probability based on the occurrence of each prize or loss other than a jackpot, thereby increasing the interest of the game.

In the slot machine according to claim (2), there is provided a counting means for counting the number of wins or losses that occur in each game for each type, and a counting means for counting the number of wins or losses that occur in each game, and based on the respective counted values of the counting means, the number of wins or losses that occur in each game is calculated. Since the display means for displaying the number of occurrences or the occurrence rate for each type and the reset operation section for resetting the counting means and display means to the initial state are provided, the player can easily check the winnings and losses for games that have already been played. If you judge that it is difficult to win based on the number of occurrences, operate the reset operation part to reset the number of wins up to that point.

You can clear the data on the number of losses and start the game from the initial state, making it even more interesting.
