DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko game machine that changes a game state according to a combination of display symbols such as numbers.

[0002]

2. Description of the Related Art In general, pachinko game machines that use pachinko balls to play games have become widespread, and pachinko halls are open everywhere, and are widely used as entertainment for ordinary people. A pachinko game is a game in which a player borrows a pachinko ball from a launching device of a pachinko game machine and wins a prize ball in a winning port provided on a game board, whereby a prize ball is refunded. In recent years, the launching device of a pachinko gaming machine can continuously launch electromechanically, and the player simply operates the handle of the launching device, and thus tends to be a monotonous game. Therefore, to increase the interest of the player,
A pachinko gaming machine equipped with a game device incorporating game elements has been developed and actually used in pachinko gaming so that anyone can obtain a large amount of prize balls fairly.

A pachinko game machine equipped with this game device updates the display contents of a variable display device for displaying numbers, characters, and symbols provided on the pachinko game machine surface based on the winning of a game ball into a specific winning opening. The present invention provides a game state more advantageous to the player (hereinafter, referred to as a jackpot, and the rest as a losing), such as opening of a winning port in accordance with the updated display content of the display device. Is intriguing with the display content displayed on the variable display device every time it is updated, and is therefore gaining in popularity. In a conventional pachinko gaming machine, when a game ball is won or detected in a specific winning opening, processing is performed by a microcomputer provided in the gaming machine, a random value is generated, and a set value of the generated random value is set. Based on the determination of the match or the mismatch, a jackpot or a loss is selected, and each control is performed. The display contents of the variable display device are updated according to the result of the selection, and the player recognizes a big hit or a loss based on the new contents. The display contents of the variable display device are generally prepared as needed for jackpots and losing, and are determined based on random numbers generated by a microcomputer. As the random number value used here, a random number value for jackpot and loss determination may be used, or an independent random number value may be used.

[0004] Such recent pachinko machines have a large number of CPU control mechanisms due to advances in electronics technology. That is, most of the game devices provided in the pachinko gaming machine are operated by the electronic technology, and the CPU device, so-called microprocessor or computer, controls and determines the operation. The role of such a computer is to calculate various information obtained from the pachinko gaming machine and the game device provided in the pachinko gaming machine, and to give a specific operation instruction to the pachinko gaming machine in accordance with a predetermined procedure (program). Things. However, these are device-oriented computerizations, and the player has no choice but to wait for the computer to make a decision.

[0005]

In the case of a pachinko gaming machine that has been converted into an electronic game as described above, the content of the game is much more varied than that of a conventional similar gaming machine. However, while playing the game for a while, the regularity of the display contents displayed on the variable display device in a certain specific operation situation becomes clear. This is because the response on the machine side becomes uniform according to a predetermined procedure or program, and because the means of generating random numbers used by the computer are of low grade, the regularity can be immediately found out. is there. On the other hand, since the player is a human, the learning effect immediately learns the correspondence on the machine side, that is, the regularity of random numbers, and loses interest in the game.
On the other hand, there was a problem that new gaming machines had to be introduced one after another as a game arcade.

In order to solve the above-mentioned drawbacks, basically, a computer system having means for generating high-quality random numbers should be installed in a game machine. In general, linear congruential methods, M-sequences, and the like are well known as high-quality random numbers. However, it is difficult to generate such high-quality random numbers with a pachinko machine that uses a simpler device that is cheaper than a general-purpose computer CPU, and conversely, a computer CPU that can generate high-quality random numbers.
Was expensive and not available. Therefore, there is a demand for a general CPU that easily generates a high-quality random number and generates the random number in a variety of ways.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to provide a gaming machine in which the regularity of the display contents provided by the gaming machine variable display device is not easily known to a player. And

[0008]

In order to solve the above-mentioned problems, the present invention relates to a variable-value display system for updating display symbols such as numbers, characters, and designs on a board based on a detection signal of a winning ball to a specific winning opening. In a pachinko gaming machine having a display device and a winning port whose mode is changed by the display content of the variable display device, the display content of the variable display device updated in response to a detection signal of a winning ball to a specific winning port is changed to a chaotic random number. A pachinko gaming machine characterized in that it is determined based on a pachinko game machine.

[0009]

[Action] First, we will explain what chaos is.
There are many predictable phenomena in the natural and man-made worlds. It can also predict and respond to Halley's comet and satellite positions. Deterministic predictability, in which the relationship between cause and effect is clear, seems to be one of the great powers of science. However, weather forecasts can be thought of as the motion of the atmosphere, which obeys the laws of physics, but often deviates. Such phenomena in which the cause and effect seem unclear are said to have random factors. Basically, if the complete parameters describing the system are clear, in other words, sufficient information about the system is collected. If possible, it was believed that accurate predictions were possible.

That is, it has been considered that the randomness is caused due to a lack of information in a multi-degree-of-freedom system. However, the discovery that even simple systems with a small number of degrees of freedom (three or more dimensions) can behave messy, suggesting that some are deterministic but have messy nature. Was found. Such randomness came to be called chaos.

[0011] However, the concept of chaos is not yet unified. Like evolution, its definition is wide-ranging and, depending on the object, the concept may even be walking alone. For this reason, in the present specification, the following will be summarized. Chaos refers to a phenomenon in which a very complex behavior appears as nonlinear but is essentially random, despite being a system with deterministic rules.
It also shows that there is a complex order and rules behind the seemingly random disorder with no regularity or predictability.

By applying such a concept of chaos mathematically and solving a specific non-linear equation, it is possible to generate very good quality random numbers. An example of this random number generation is a one-dimensional nonlinear difference equation described by a mapping r from section to section.

[0013]

X _{n + 1} = r (x _n ) n = 0, 1,.

May have an irregular and messy solution called chaos. Simple examples of such non-linear mapping include Bernoulli shift, logistic mapping, tent mapping, Chebyshev mapping, and the like. For example, the Bernoulli shift is

[0015]

(Equation 2)

The logistic mapping is

[0017]

R (x _n ) = bx _n (1−x _n )

In particular, in Equation 3, when b = 4.0, it is called "pure chaos". Also,
What is a tent map?

[0019]

(Equation 4)

What is the Chebychev map?

[0021]

R (x _n ) = cos ( _n cos ⁻¹ x _n )

Each of the solutions of these equations is a chaotic random number, and the regularity of the random number is not normally known. In addition to these mappings, it is possible to generate chaotic random numbers. Note that in this specification, sections
One-dimensional nonlinear difference equation described by a mapping r to

[0023]

X _{n + 1} = r (x _n ) n = 0, 1,.

The random and random solution obtained when solving
Defined as chaotic random numbers.

[0025] For example, in the logistic map, the slide into changing the variable b in the equation, solutions obtained varies, as b approaches 4, the resulting solution is from 0.0 1.
It has a solution within the range of 0 and becomes closer to chaotic random numbers. Conversely, by changing this variable, it is possible to limit the obtained solution. For example, when b is 2, the obtained solution converges to one, and when b is around 3.5, the solution becomes 4 To converge. Further, as the value of b approaches 4, this restriction is reduced, and the solution takes a chaotic random number within a certain range.

[0026] This is shown in Figure 3. Figure 3 is a logistic map

Equation 3] in _{r (x n) = bx n} (1-x n), an initial value Xo of 0.3, the variable b 0 to 4
N = 30 when calculated up to n = 500 when changed to
The values of the solutions obtained from 0 to 500 are shown. The value on the vertical axis corresponding to the position of the black point in the figure is the value of the solution. As described above, when b is smaller than around 3, the solution converges to any one, and when b is around 3.1 to 3.4, the solution is 2.
One has converged. Furthermore, as b increases, the solution becomes 4
The number of converging places increases, for example, eight, and chaotic random numbers are gradually taken.

[0027] using a chaotic random number generated in such a generation method, constituting the game machine of the present invention. This gaming machine has at least a random number generation unit that can generate the chaotic random number, and a computer unit that issues instructions of various display contents to the variable display device based on the random number generated by the random number generation unit. This is to prevent the contents from being easily revealed to the player.

[0028] For example, the player starts pachinko, the gaming ball enters a particular winning hole, big hit based on the winning ball detection signal, determines the loss is made, the display contents determined by the chaotic random number variable display device Is displayed.

On the other hand, as described above, by changing the variables of the equation, it is possible to restrict the solution,
This can be used to control the generation of random numbers. That is, this variable is set as a part of the game condition, and the solution of the above equation is obtained under this condition, and the display content is changed by the solution. In this way, when the displayed content is changed in accordance with the solution of the equation, the correspondence at the time of a specific number of variables is different from the correspondence at the time of another variable. Can be configured.

Embodiment 1 An embodiment of the present invention will be described with reference to the following drawings. FIG.
Denotes a front panel 1 of the pachinko gaming machine. 1 is a pachinko ball firing handle, 2 is a game board surface, and on this board surface 2 prize holes 46, 7, 8; a display panel 5 of the game device; a prize hole 3 having a game device starter chucker function; Is provided. The pachinko ball fired from the firing device is hit in various directions by nails provided on the game board surface and moves downward on the board surface 2.

[0031] In this case, when the pachinko ball has entered the winning holes 4, 6, 7, 8, the prize balls are paid out to the pachinko ball saucer section 12 of the player. In particular, when a pachinko ball enters the winning opening 3, the game device is started in addition to the payout of the prize ball. This device changes the three-digit display of the variable display unit 5 and stops the change of the display after a predetermined time elapses. When a specific display combination is established, the opening and closing valve of the special winning opening 9 is opened. Command to open and close. As a result, the pachinko gaming machine opens the on-off valve of the special winning opening 9 to provide an advantageous situation for the player in which the pachinko ball is easily entered.

[0032] Now, pachinko balls are fired from the launching device 1 Yuki fallen on board, to be converted into an electric signal is detected winning by a sensor provided in the winning hole 3 and enters the winning hole 3 computer Sent. In response to this signal, the computer generates a random number value by the random number generation means. The generated random number value is compared with the set value,
By the determination of the disagreement, each control of the jackpot or the loss is performed thereafter. In the present embodiment, the generation of the random number value used for the determination of the jackpot or the loss is performed by taking out a numerical value from a random number counter that is updated as needed in the range of 1 to 219. The random number counter value is set so as to be incremented by about 1 every about 4 ms, forming an infinite loop of 1 to 219. Although the random number counter value itself fluctuates regularly, the timing of taking out the numerical value from the counter depends on the timing of detecting the winning of the winning ball into the winning opening 3, so that a certain irregularity of the taken out value occurs. .

The jackpot in the above determination, either losing is determined to display the compatible display content in each case on the variable display device. In the present embodiment, the display contents displayed on the three display portions of the variable display device are a total of 1 to 9 numerals and alphabets of A, B, C, D, E, and F, respectively.
There are a total of 3375 types composed of five types. The display contents displayed on the variable display device in each case of the jackpot and the loss are such that the display contents of three places match in the case of the jackpot.
In the case of a loss, at least one of three display contents is selected from 3360 different from other display contents in the case of a loss.

In this embodiment, the chaotic random numbers to be generated are classified into 3375 types, and each group is made to correspond to the display contents of the variable display device. The chaotic random numbers are generated at any time during the game. If the generated random numbers are classified into groups corresponding to the display content at the time of the big hit, the memory area for the big hit display, Display data is stored in the display memory area. Until new data is stored in each display memory area, the previous data is held. In the present embodiment, since the chaotic random numbers that can be generated exist in the numerical range of 0.000 to 1.000, the numerical range is divided into 3375 and compared with the generated chaotic random numbers to obtain the seeds of the random numbers. Divide. When a jackpot or a loss is confirmed by the computer by confirming the winning ball in the winning opening 3, the jackpot or the loss display memory area at that time is referred to, and the display according to the stored data is displayed on the variable display device.

In this embodiment, the following equation using a logistic map for the nonlinear difference equation

[0036]

X _{n + 1} = 4X _n (1−X _n )

[0037] solution as chaos random number which was used. In this case, the initial value was 0.1, and the variable was 4.0000. This chaotic random value is classified into 3375 ways as described above,
The data is stored in a jackpot or loss display memory.

FIG . 2 is a block diagram of a pachinko game machine equipped with a computer. The sensor detects the winning ball at the winning opening 20 by the sensor, and receives the signal to generate a chaotic random number 25 in the computer 21 and determines the display content of the variable display device based on the random number. Further, the game information 22 can be linked to the computer by other sensor means, and the information can be linked to the grasp 20 of the winning balls of the pachinko ball, so that more complicated game contents can be obtained.

[0039] In the "Example 2" Example 1, data stored in the memory for jackpot or loss displayed by determining the chaotic random numbers, since the storage of new data until is performed, the old data is retained In particular, it is assumed that the update frequency of the jackpot display data decreases. Therefore, in this embodiment, two independent chaotic random numbers are used for determining the jackpot and the loss display content of the variable display device. In other words, the chaotic random numbers generated for the jackpot display are classified into 15 types, and the chaotic random numbers generated for the loss display are classified into 3360 types to correspond to the respective display contents.

The random numbers for the chaos for the jackpot and the losing are generated as needed, and stored in the memory area for the jackpot and the losing, respectively. Therefore, if the generation cycle of both chaotic random numbers is set to be the same, the update frequency of each display content designation data to be updated can be made equal.

In the above embodiment, the chaotic random number was obtained by executing a program on a computer, but the chaotic random number may be obtained using a dedicated integrated circuit or the like.

In the present invention, it is effective to provide a means for intentionally or automatically changing the initial value of a nonlinear equation used for generating chaotic random numbers.

[0043]

According to the structure of the present invention, a pachinko gaming machine in which a player does not easily feel regularity in pachinko gaming can be provided by using an inexpensive and simple CPU. In addition, since numerical values required for the game can be obtained only by solving a relatively simple nonlinear equation, various numerical values can be easily obtained according to the content of the game.
