Abstract

A game machine for providing a game, the regularity of which cannot be easily recognized by the player, by making use of a chaotic random number produced by a random number generating means.

Claims

1. A method of driving a game machine comprising:

generating a random number in a random generating unit disposed in a computer; and

changing difficulty level of a game conducted in said game machine by changing regularity of said random number,

wherein said regularity of said random number is changed depending upon a playing condition of said game conducted in said game machine.

4. A method according to claim 1 wherein said game machine is a pachinko machine or a slot machine.

5. A method according to claim 1 wherein said random generating unit generates said random number a plurality of times.

6. A method according to claim 1 wherein said random generating unit comprises an integrated circuit.

7. A method according to claim 1 wherein a variable of a nonlinear equation is changed depending upon the playing condition of said game conducted in said game machine, and said regularity of said random number is changed depending upon said variable of said nonlinear equation.

8. A method according to claim 7 wherein said nonlinear equation is a logistic mapping.

9. A method according to claim 7 wherein said nonlinear equation is a one-dimensional nonlinear differential equation.

2. A method of driving a game machine comprising:

generating a random number in a random generating unit connected with a computer; and

changing difficulty level of a game conducted in said game machine by changing regularity of said random number,

wherein said regularity of said random number is changed depending upon a playing condition of said game conducted in said game machine.

10. A method according to claim 2 wherein said game machine is a pachinko machine or a slot machine.

11. A method according to claim 2 wherein said random generating unit generates said random number a plurality of times.

12. A method according to claim 2 wherein said random generating unit comprises an integrated circuit.

13. A method according to claim 2 wherein a variable of a nonlinear equation is changed depending upon the playing condition of said game conducted in said game machine, and said regularity of said random number is changed depending upon said variable of said nonlinear equation.

14. A method according to claim 13 wherein said nonlinear equation is a logistic mapping.

15. A method according to claim 13 wherein said nonlinear equation is a one-dimensional nonlinear differential equation.

3. A method of driving a game machine comprising:

changing a first difficulty level of a game conducted in said game machine to a second difficulty level of said game by changing a first regularity corresponding to a first random number to a second regularity corresponding to a second random number;

continuing said game under said second difficulty level; and

changing said second difficulty level of said game to a third difficulty level of said game by changing said second regularity to a third regularity corresponding to a third random number.

16. A method according to claim 3 wherein said game machine is a pachinko machine or a slot machine.

17. A method according to claim 3 wherein said first random number is obtained by solving a nonlinear equation with a first variable, and said second random number is obtained by solving said nonlinear equation with a second variable, and said third random number is obtained by solving said nonlinear equation with a third variable.

18. A method according to claim 17 wherein said nonlinear equation is a logistic mapping.

19. A method according to claim 17 wherein said nonlinear equation is a one-dimensional nonlinear differential equation.

20. A method according to claim 17 wherein said third variable is same as said first variable.
