Abstract

A pair of electronic oscillator/feedback shift register/decoding circuitry combinations are used for a game of dice. Each of these combinations is arranged to randomly generate numbers in six states (1-6) and to independently display the numbers so generated by each combination upon actuation by the player, as by pressing a button. The states prevailing in the separate feedback shift registers upon cessation of pulse input are decoded and displayed to represent the results of a dice throw by the player.

Claims

1. A simulated dice game for producing truly random die combinations on each die and reflecting true dice odds for each play of the dice comprising in combination:

a. a first oscillator having a frequency of electric pulse generation in excess of about 100,000 cycles per second, b. a second oscillator having a frequency of electric pulse generation in excess of about 100,000 cycles per second, pulse generation in said first oscillator being independent of and at a different rate than pulse generation in said second oscillator, c. means electrically connected to said first and second oscillator for actuation thereof, said means for actuation being adapted for selective manual activation and deactivation, d. first means electrically connected to receive the pulse output from said first oscillator for generating changes in bilevel states in response to pulse input thereto, the changing states proceeding in a fixed repetitive sequence of six distinct states, e. second means electrically connected to receive the pulse output from said second oscillator for generating changes in bilevel states in response to pulse input thereto, the changing states proceeding in a fixed repetitive sequence of six distinct states, f. first decoding means electrically connected to said first generating means for decoding bilevel output signals received therefrom to reflect the prevailing state therein, g. second decoding means electrically connected to said second generating means for decoding bilevel output signals received therefrom to reflect the prevailing state therein, h. first display means electrically connected to said first decoding means, said first display means being driven by said first decoding means in response to the decoding function conducted thereby to display at any instant the particular state prevailing in said first generating means, and i. second display means electrically connected to said second decoding means, said second display means being driven by said second decoding means in response to the decoding function conducted thereby to display at any instant the particular state prevailing in said second generating means.

2. The simulated dice game as recited in claim 1 wherein the first and second oscillators are regenerative oscillators that operate at frequencies of about one million cycles per second.

3. The simulated dice game as recited in claim 2 wherein each means for changing bilevel state is a feedback shift register and each decoding means comprises seven output drivers arranged to decode the six states of the register connected thereto into four display conditions taken singly or in combination to cause the display means connected thereto to sequentially reflect the prevailing states in said register, each display means comprises seven low voltage lamps, the arrangement of said output drivers being as follows:

a. the first, second, fourth and fifth drivers are individually electrically connected to four separate output terminals of said register, b. the third and sixth drivers are electrically connected in common to a fifth output terminal of said register, c. the output of said first driver is electrically connected to a first lamp, d. the outputs of said second and third drivers are electrically connected in common to second and third lamps arranged in parallel, e. the output of said fourth driver is electrically connected to a fourth and fifth lamp arranged in parallel and f. the fifth, sixth and seventh drivers are interconnected with the outputs of said fifth and sixth drivers being applied in common to said seventh driver, the output of said seventh driver being electrically connected to the sixth and seventh lamps arranged in parallel.

4. The simulated dice game as recited in claim 1 wherein the means for actuation of the oscillators comprises switches for separately actuating either oscillator and a switch for simultaneously actuating both oscillators.
