Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine which changes a game content based on a chaotic random number generated by means for electronically generating a chaotic random number.

[0002]

2. Description of the Related Art In general, pachinko machines for playing games using pachinko balls have become widespread, and pachinko halls are operating everywhere, which is widely enjoyed by ordinary people. The pachinko game is a game in which a player releases a prize ball by launching a pachinko ball borrowed by a player from a launching device of a pachinko gaming machine and winning a prize at a winning opening provided on a game board surface. The launching device of a recent pachinko gaming machine can be electromechanically continuously launched, and since the player merely operates the handle of the launching device, the game tends to be monotonous. Therefore, to increase the interest of the player,
In addition, a pachinko game machine equipped with a game device incorporating a game element has been developed and actually used in a pachinko game so that a large amount of prize balls can be fairly obtained by anyone.

A pachinko gaming machine equipped with this game device activates the game device when predetermined conditions are met,
Depending on the situation of this game device, it decides the correspondence of the pachinko game and provides the player with a more advantageous game state, and a machine that obtains more prize balls regardless of the skill level of the player is obtained. Therefore, it is gaining popularity.

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 electronic technology, and the CPU device, so-called microprocessor or computer, controls and determines this operation. The role of such a computer is to calculate various information obtained from a pachinko gaming machine and a game device provided in the pachinko gaming machine, and give a specific operation instruction to the pachinko gaming machine according to a predetermined procedure (program). It is a thing. However, these are computerizations on the device side, and the player can only wait for a decision to make a computer.

In addition to the pachinko game machine, recently, a rotating-body type game machine (generally called a slot machine or a pachi-slot machine) having a rotating-body type picture matching section has been popular as an entertainment like the pachinko game. ing. This spinning drum type gaming machine is a game in which coins are inserted, a start button is pushed, a spinning barrel type design is rotated, and a prize coin is obtained by a combination of the designs.

This gaming machine also has a large number of computer control mechanisms due to the progress of electronic technology as in the case of pachinko gaming. That is, most of the rotating drum type picture matching section is operated by electronic technology, and it is a computer device, a so-called microprocessor, that controls and determines this operation. The role of such a microprocessor is to calculate various kinds of information obtained from the gaming machine and the pattern matching unit and give a specific operation instruction to the gaming machine according to a predetermined procedure (program). Similarly, the game tends to be monotonous.

[0007]

In the case of an electronic pachinko gaming machine or a spinning drum type gaming machine as described above, the contents of the game are remarkably rich as compared with the conventional similar gaming machines. Has become. However, while playing a game for a while, the correspondence that the gaming machine takes in a certain specific operation situation becomes clear. This is according to the procedure or program in which the correspondence on the machine side is predetermined,
This is because they are uniform, and because the means of random number generation used by computers are low-grade, their regularity is immediately known. 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 the interest in the game is lost. On the other hand, as a game hall, there was a problem that new game machines had to be introduced one after another.

In order to solve the above-mentioned drawbacks, basically, a computer system having means for generating good-quality random numbers may be installed in the game machine. As a high-quality random number, the linear congruential method, the M series, etc. are generally well known. However, it is difficult to generate such a high-quality random number in a pachinko machine that uses a simple and inexpensive one as compared to the CPU of a general-purpose computer, and conversely, a CPU of a computer that can generate a high-quality random number.
Was expensive and unavailable. Therefore, there is a demand for an ordinary CPU that can more easily generate high-quality random numbers and that has a variety of generation methods.

[0009]

In order to solve the above problems, the present invention provides a game machine in which the regularity of the game contents provided by the game machine is not easily known to the player. To aim.

[First Invention] A gaming machine which provides a game in which a player cannot easily know the regularity of a game by utilizing a chaotic random number generated by a random number generating means.

[Second Invention] A plurality of pachinko ball winning openings and a grasping means for grasping a winning situation of a pachinko ball provided in a predetermined winning opening among the winning openings and a random number generating means capable of generating chaotic random numbers are specified. Pachinko gaming machine having at least a computer capable of instructing the control of the winning situation of the winning port.

[Third Invention] A spinning-roller type gaming machine having at least a rotary display unit, a random number generating means capable of generating chaotic random numbers, and a computer capable of instructing control of display on the display unit.

[Fourth Invention] A game machine characterized in that a numerical value obtained by solving a non-linear difference equation is used as one condition for determining a change in game content.

[Fifth Invention] A game machine according to a fourth aspect is characterized in that the regularity of a solution obtained from the equation is changed by changing a variable of the nonlinear equation. Amusement machine.

[0015]

[Operation] First, let us explain what chaos is.
There are many predictable phenomena in the natural and man-made worlds. It is also possible to predict and respond to the positions of Comet Halley and satellites. Deterministic predictability, in which the relationship between cause and effect is clear, seems to be one of the great forces of science. However, weather forecasts, often thought of as atmospheric motions that follow the laws of physics, often deviate. Such a phenomenon in which the cause and effect are unclear is said to have random elements. Basically, if the complete parameters that describe the system are clear, in other words, sufficient information about the system is collected. It was believed that accurate predictions were possible, if possible.

That is, randomness was considered to occur due to lack of information for the multi-degree-of-freedom system. However, the discovery that even a simple system with a small number of degrees of freedom (three or more dimensions) can exhibit random behavior may lead to the existence of deterministic but randomness. Was found. This kind of disorder has come to be called chaos.

However, the concept of chaos is not yet unified. Like evolution, its definition extends over a wide area, and it feels like the concept is walking alone depending on the object. Therefore, in this specification, the following will be summarized. Chaos means a phenomenon in which a very complicated behavior appears as a non-linearity, resulting in an essentially random phenomenon, even though the system has deterministic rules.
It also shows that there is a complicated order and law behind the phenomenon of seemingly disorderly disorder without regularity or predictability.

By applying the above-mentioned idea of chaos mathematically and solving a specific nonlinear equation, it is possible to generate a very good random number. An example of this random number generation is a one-dimensional nonlinear difference equation described by a mapping r from section to section.

[0019]

[Equation 1]

May have an irregular and random solution called chaos. Simple examples of such a non-linear map include Bernoulli shift, logistic map, tent map, and Chebychev map. For example, Bernoulli shift is

[0021]

[Equation 2]

The logistic map is

[0023]

[Equation 3]

Particularly in Expression 4, when b = 4.0, it is called "pure chaos". What is a tent map?

[0025]

[Equation 4]

What is the Chebychev map?

[0027]

[Equation 5]

The solution of each of these equations is a chaotic random number, and normally the regularity of this random number is not known. It is possible to generate chaotic random numbers other than these maps.

For example, in the logistic mapping, when the variable b in the equation is changed, the obtained solution changes, and as b approaches 4, the obtained solution is from 0.0 to 1.
It has a solution within the range of 0 and approaches a more chaotic random number. On the contrary, if this variable is changed, the obtained solution can be limited. For example, when b is 2, the obtained solution converges to 1, and when b is around 3.5, the solution is 4 Converge to one. Further, as this b approaches 4, the limitation becomes less and the solution takes a chaotic random number within a certain range.

This state is shown in FIG. Figure 3 is a logistic map

In Equation 3, the initial value Xo is set to 0.3, and the value of the solution obtained when n = 300 to 500 is calculated when n = 500 is calculated when the variable b is changed from 0 to 4. . The value on the vertical axis corresponding to the position of the black dot in the figure is the value of the solution. As described above, the solution converges to one when b is smaller than around 3, and to two when b is around 3.1 to 3.4. Furthermore, when b becomes large, there are four or eight solutions, so there are more places to converge,
It gradually takes chaotic random numbers. However, for example, when b is set to 4, while repeating the calculation,
Depending on how to take significant digits when performing arithmetic processing, the solution may become 0.5 after a certain number of iterations. All subsequent solutions are 0.5, so it is effective when performing arithmetic processing. If you do not pay attention to how to take numbers and the range of iterations that use the solution, it may not be a random number suitable for chaos.

The game machine of the present invention is constructed by utilizing the chaotic random numbers generated by such a generating method. This gaming machine has a random number generator that can generate the chaotic random number, a computer unit that gives various instructions by the random numbers generated by the random number generator, and a portion that changes the correspondence of the game according to instructions from this computer. Have at least
This prevents the contents of the game from being easily revealed to the player.

For example, in the case of a pachinko gaming machine, first, when a player starts a pachinko machine and a safe ball enters a predetermined safe ball receiving portion, the safe ball detecting means detects the safe ball and electronically operates it. Generate chaotic random numbers. Then, on the basis of the chaos random number generated electronically, the incoming state of the safe ball receiving portion of the game machine board surface is controlled.

On the other hand, as described above, the solution can be restricted by changing the variables of the equation.
This can be used to control the generation of random numbers. That is, using this variable as a part of the game condition, the solution of the above equation is obtained under this condition, and the content of the game is changed by the solution. In this way, when changing the contents of the game according to the solution of the equation, the correspondence of the game when a certain number of variables is different from the correspondence of the game when another variable, More complex games can be configured.

On the contrary, since the solution obtained by solving the equation can be made not a random number, the variable is changed to a specific value in order to realize a situation particularly advantageous for beginners or for the player. However, by setting the situation where the solution of the equation is easy to give a specific numerical value, and by setting the game content that is advantageous to the player by this numerical value, it is possible to easily change the difficulty level of the game or complicate and simplify the content. Can be realized.

【Example】

Example 1 In this example, an example applied to a pachinko game is shown. Embodiments of the present invention will be described with reference to the following drawings. FIG. 1 shows a board surface 1 on the front surface of a pachinko gaming machine.
Reference numeral 1 is a pachinko ball launching handle, 2 is a game board surface, and on the board surface 2, winning holes 46, 7, 8, a display board 5 of the game device, a winning hole 3 having a starting chucker function of the game device, and a large winning hole 9 Is provided. The pachinko ball launched from the launch device is a nail provided on the game board surface,
It bounces in various directions and moves downward on the board 2.

At this time, when a pachinko ball enters the winning opening 3, 4, 6, 7, or 8, the prize ball is paid out to the pachinko ball saucer portion 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 game device display unit 5 to stop the change of this display after a lapse of a predetermined time. Command to open and close. Thus, as a jackpot under certain conditions, the pachinko gaming machine opens the open / close valve of the special winning opening 9 to provide an advantageous situation for the player to easily enter the pachinko ball.

Now, when the pachinko ball fired from the launching device 1 falls on the board surface and enters the winning opening 3, the sensor provided in the winning opening 3 detects the winning and is converted into an electric signal to be computerized. Sent. This signal causes the computer to operate the game apparatus 5 to display the game apparatus in accordance with the chaotic random number generated by the chaotic random number generating means.

In this embodiment, the following equation using the logistic map for the nonlinear difference equation is used.

[0038]

[Equation 6]

The solution of was used as a chaotic random number. For example, when n = 301, 302, 303, 304, 305, as an example of the solution of this equation, “0.8721” and “0.4
462 ”,“ 0.9884 ”,“ 00458 ”,“ 0.
1747 ”. In this case, the initial value was 0.1 and the variable was 4.00.

When this chaotic random number matches the preset condition, the opening / closing valve of the special winning opening 9 on the game board surface is opened / closed by the instruction of the computer. The state of opening and closing of this valve is different depending on the generated random number, and according to this random number, the computer instructs the winning situation such as the time interval of opening and closing or the degree of opening and closing, and changes the open and closed state according to the instruction.

FIG. 2 is a block diagram of a pachinko gaming machine equipped with a computer. The sensor detects the safe ball at the winning opening 20, receives the signal, and causes the computer 21 to generate 25 a chaotic random number, and the big winning opening is controlled 23 by this random number. Further, the game information 22 can be linked to the computer by other sensor means, and this information and the grasp 20 of the safe ball of the pachinko ball can be linked to make a more complicated game content.

[Embodiment 2] In this embodiment, a spinning-type gaming machine will be described. When a coin inserted by the player or a start button is started, a signal for starting a game is given to the computer, and a chaotic random number is generated in the computer section or in a random number generating section provided in conjunction therewith. According to the generated random number, the display of the revolving type is displayed, and a combination of this display pays out a predetermined multiple of coins with respect to the inserted coin. By using chaotic random numbers as in the present embodiment, the regularity at the time of random number generation is unknown, and for all players,
Prize coins can be paid fairly with the same probability.

[Embodiment 3] In this embodiment, for the same pachinko gaming machine as in Embodiment 1, it will be explained that the generation of the numerical values used in the game is changed depending on the game condition. The configuration of the gaming machine or the like used is almost the same as that of the first embodiment. However, it is connected to a sensor for grasping the safe ball of the winning opening 3 that triggers the start of the game, and a means for counting the number of winnings is added, and the number of winnings is sent to the computer as a signal. Has become. Separately, means for counting the number of winnings may be provided in the computer.

Now, when the pachinko ball fired from the launching device 1 falls on the board surface and enters the winning opening 3, the sensor provided in the winning opening 3 detects the winning and is converted into an electric signal and is converted into a computer. Sent. This signal causes the computer to operate the game apparatus 5 to display the game apparatus in accordance with the chaotic random number generated by the chaotic random number generating means.

In the present embodiment, the following mathematical expression using the logistic map for the nonlinear difference equation is used.

[0046]

[Equation 6]

The solution of was used as a chaotic random number. In this case, the initial value was 0.1 and the variable was 4.

When the chaotic random number matches the preset condition, the opening / closing valve of the special winning opening 9 on the game board surface is opened / closed according to the instruction of the computer, which is a so-called big hit state. On the contrary, if the condition is not met,
When the number of winnings to the winning opening 3 continues, for example, 10 times, the computer changes the value of the variable b in order to limit the numerical value to be generated, and sets the condition to give regularity to the generation of random numbers.

For example, when the value of the variable b is 3.50, it is obtained when the safe ball is next won in the winning opening 3.
If the equation is solved 100 times or more,
Converges to one value. If any one of these eight is set as a jackpot condition, the jackpot probability increases to 1/8. Next, if the jackpot condition is not met even if the player wins five times in this state, the value of the variable is returned to around 4 again to the state of the chaotic random number. In this way, by controlling the numerical value obtained by solving the equation, if the player is in a disadvantageous situation, changing to a more advantageous situation or returning to the initial state again by changing a simple variable It was possible to realize, and by doing so, it was possible to easily make the game contents rich in changes.

In the above description, a pachinko gaming machine and a spinning drum type gaming machine have been described, but the gaming machine is not particularly limited to these, and games played using random numbers or simple irregular numerical values. Any machine can be applied to any game machine.

[0051]

According to the configuration of the present invention, it is possible to provide a game in which the regularity is not easily understood in the game and which is inexpensive and which uses a simple CPU. Also, the numerical value required for the game can be obtained only by solving a relatively simple non-linear equation, and the solution can also be obtained by changing the variable in the equation from chaotic random number to binary or one value. Therefore, it became possible to easily obtain various numerical values according to the contents of the game.
