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.

The practice is also known as telebetting or proxy betting, because betting is done by a proxy in the room, talking by phone with the player, who will already have an account with the room and/or junket promoter, making settlement simple.
