Roulette-type gaming machine - has EM drive unit for disc playing pieces producing pulsating magnetic field controlled in pulse duration and-or frequency by random generator

摘要

The gaming machine has a target ring turning about a horizontal axis and made with a coaxial border of target places, each with a number. By means of an electromagnet ring, magnetisable pieces (14) are accelerated by a carrier disc (17) in the direction of the target ring and stopped at one of the target places. This playing piece is a flat, circular coin like body. The carrier disc is held stationary and has guiding walls (25) on its face for a funnel shaped channel (26) leading from the upper edge to the lower edge of the disc so that a ball can fall under its own weight to the target ring. At the upper end of the channel (26a) on the carrier disc at least one electromagnet (27) holds a ball until released by a player. An e.m. arrangement (28) lower down produces a pulsating magnetic field, with a period and frequency controlled by a random number generator. The pulse spacing is selected so that there is more probability of it influencing a falling ball. ADVANTAGE - Player seems to have greater effect on play.
