A probability of 100 percent means the safe arrival of an event, and a value of 0, the safe lack of an event. The payout ratio for a bet depends on its probability. Players can continue to place bets as the ball spins around the wheel until the dealer announces 'no more bets' or 'rien ne va plus'. The roulette desk usually imposes minimum and maximum bets. In addition to the payouts, you get back your original bet amount.
