roulette, (from French: small wheel ), gambling game in which players bet on which red or black numbered compartment of a revolving wheel a small ball (spun in the opposite direction) will come to rest within. Bets are placed on a table marked to correspond with the compartments of the wheel.
Spin the wheel works by offering entrants the opportunity to win prizes determined by spinning a virtual wheel that will land on a random segment. Each segment offers a different prize or offer. This means there is always a chance to win something, regardless of where the segment lands.
