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 game machine comprising;

a computer; and

a random generating unit disposed in said computer for generating a random number,

wherein difficulty level of a game conducted in said game machine is changed by changing regularity of said random number, and

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

2. A machine acording to claim 1 wherein said game machine is a pachinko machine or a slot machine.

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

4. A machine 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 plurality of said random number is changed depending upon said variable of said nonlinear equation.

5. A machine according to claim 4 wherein said nonlinear equation is a logistic mapping.

6. A machine according to claim 4 wherein said nonlinear equation is a one- dimensional nonlinear differential equation.

7. A game machine comprising:

a computer; and

a random generating unit connected with said computer for generating a random number,

wherein difficulty level of a game conducted in said game machine is changed by changing regularly of said random number, and

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

8. A machine according to claim 7 wherein said game machine is a pachinko machne or a slot machine.

9. A machine according to claim 7 wherein said random generating unit generates said random number a plurality of times.

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

11. A machine according to claim 10 wherein said nonlinear equation is a logistic mapping.

12. A machine according to claim 10 wherein said nonlinear equation is a one- dimensional nonlinear differential equation.

13. A game machine comprising:

a computer; and

an integrated circuit disposed in said computer for generating a random number,

wherein difficulty level of a game conducted in said game machine is changed by changing regularity of said random number, and

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

14. A machine according to claim 13 wherein said game machine is a pachinko machine or a slot machine.

15. A machine according to claim 13 wherein said integrated circuit generated said random number a plurality of times.

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

17. A machine according to claim 16 wherein said nonlinear equation is a logistic mapping.

18. A machine according to claim 16 wherein said nonlinear equation is a one- dimensional nonlinear differential equation.

19. A game machine comprising:

a computer; and

an integrated circuit connected with said omputer for generating a random number,

wherein difficulty level of a game conducted in said game machine is changed by changing regularly of said random number, and

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

20. A machine according to claim 19 wherein said game machine is a pachinko machine or a slot machine.

21. A machine according to claim 19 wherein said integrated circuit generates said random number a plurality of times.

22. A machine according to claim 19 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.

23. A machine according to claim 22 wherein said nonlinear equation is a logistic mapping.

24. A machine according to claim 22 wherein said nonlinear equation is a one-dimensional nonlinear differential equation.
