Abstract
A casino dolly for use in a roulette game includes sensors, preferably using passive infra red detection, to detect the presence of a hand or movement of chips in an area around the dolly. When the dolly is placed on the area of a winning number on a roulette board it will act to set off an alarm if the sensors detect an attempt to place late bets in the area around the dolly.
