The first thing on the list is electromagnets. These are placed in four spaces equally; they are placed around the roulette's stationary bowl. The magnet is used in alignment with the ball bearing the steel core. If the magnetic force is activated, the ball is driven off the top race and brought down. The dealer will have a hidden button to help control the ball. A skilled dealer is needed to control the ball. He would be familiar with the layout of the roulette wheel. The dealer then can easily maneuver the ball away from numbers with high bets.
