Casino Royal


A simple counter-display circuit can be adapted to a game of chance for up to seven players, with a built-in provision to insure that “The house never loses.” Note that all seven display segments, like the previous circuitry, have only

one connection. Three outputs (pins 8, 9, 10) now go to the decimal point, via isolating diodes D1 D2, and D3. This gives “The House” a 3 out of 10 chance to take all bets. The clock should be set to provide a rapidly flickering display when the push-button switch is depressed. When the player holds down the switch for a few seconds and releases it, one of the segments, or the decimal point will remain lighted. . and the odds are on the Point!
