In an establishment in which wagers are placed on the outcome of a fortuitous event, such as the roll of a pair of dice, the spin of a roulette wheel, the result of a horse race, or the like, a player operates a remote selector panel on which a register displays a previously established credit balance. Bets on the event are made from the panel by wagering any amount up to the limit of the credit balance. The amount wagered is automatically deducted from the credit balance, and in the event of a win the amount wagered is multiplied by a predetermined odds factor for the event and added to the credit balance.
