Roulette is a casino and gambling game
named after a French diminutive for "little wheel". In the game, players
may choose to place bets on either a number, a range of numbers, the
colors red or black, or whether the number is odd or even. To determine
the winning number and color, a croupier spins a wheel in one direction,
then spins a ball in the opposite direction around a tilted circular
track running around the circumference of the wheel. The ball eventually
loses momentum and falls on to the wheel and into one of 37 or 38
colored and numbered pockets on the wheel.
Players wishing to play roulette have a variety of betting options.
Placing 'inside' bets is either selecting the exact number of the pocket
the ball will land in, or a small range of pockets based on their
proximity on the layout. Players wishing to bet on the 'outside' will
select bets on larger positional groupings of pockets, the pocket color,
or whether the winning number is odd or even.[3] The payout odds for
each type of bet is based on its probability.
When a winning number and color is determined by the roulette wheel, the
dealer will place a marker also known as a dolly on that winning number
on the roulette table layout. When the dolly is on the table, no players
may place bets, collect bets, or remove any bets from the table. The
dealer will then sweep away all other losing bets either by hand or
rake, and determine all of the payouts to the remaining inside and
outside winning bets. When the dealer is finished making payouts, the
marker is removed from the board where players collect their winnings
and make new bets. The winning chips remain on the board.
