Method for the determination of stop positions of rotating reel bodies of a game display device of a gambling machine
First Claim
1. A method for determining stop positions of displayed rotating reels comprising the stepsinitiating a game;
- determining a pseudo-random number with a pseudo-random number generating means;
comparing the pseudo-random number with numbers in subsets of a set of numbers generatable by the pseudo-random number generating means;
determining the subset associated with the pseudo-random number and a win class associated with the subset;
determining a symbol combination associated with the win class;
determining in the control unit if the symbol combination is displayable based on conditions imposed relating to a starting position of the displayed rotating reels and relating to the time period of rotation permissible for the displayed rotating reels;
rejecting a symbol combination which is not displayable, and repeating the above steps by and upon determining a next following pseudo-random number with the pseudo-random number generating means.

Abstract
A random number generator determines the stop positions of display means of entertainment machines and of gambling machines. The random number generator is a component of the control unit which assumes the sequential play control. A uniform stopping of the rotating reel body is made possible and the stop positions cannot be reconstructed and predicted. In order to stop the rotating reel body in a non-reconstructable but uniform way in specific symbol-combination-displaying rest positions, a disjoint subset of the set of numbers accessible by the pseudo-random number generator is coordinated to each win class. Subsequently, a pseudo-random number is generated by the pseudo-random number generator and a win class is associated to this pseudo-random number. The symbol combination of the thus determined win class to be displayed is subsequently displayed with the rotating reel bodies stopped in position displaying symbols associated with the win class.

12. A method for determining stop positions of displayed rotating reels of a game device or gambling machine comprising the steps of:
-
providing a gambling machine having a plurality of rotating reels, each reel having a plurality of symbols; providing the gambling machine with a control unit with a microcomputer for controlling the game process; determining positions of the rotating reels based on a pseudo-random control system; initiating a rotation of the rotating reels; observing the positions of the displayed rotating reels with position-recognizing sensors connected to the control unit and disposed on the side of the displayed rotating reel; stopping the displayed rotating reels with the control unit in predetermined positions; classifying obtainable winning situations into win classes; coordinating a disjoint subset of a set of numbers to each win class; determining a pseudo-random number within the set with a pseudo-random number generator, whereby the win class is determined based on the subset containing the pseudo-random number; displaying a symbol combination associated with the win class on the displayed rotating reels; providing the symbol combination to be displayed starting from a precedingly to be displayed symbol combination within a given total number of steps between two predetermined values representing a band width; rejecting the symbol combination in case of non-displayability of the symbol combination between the two predetermined values representing a band width of the total step numbers; and determining a new win class based on a different pseudo-random number. - View Dependent Claims (13, 14, 15)
