a
reference to roulette, a gambling
game played with a
wheel set into a bowl shape in the middle of an oblong table. The
wheel is divided into thirty-seven small compartments numbered from
zero to thirty-six and
colored alternately
red and black, except the
zero (which is either white or
green). The table is covered with a
layout that corresponds to the
numbers and colors on the roulette
wheel where players visibly
place their bets. The
wheel is
spun and an operator rolls the
ball in the opposite direction to that which the
wheel is
spinning. After bouncing around the
ball drops onto the
wheel eventually settling in one of the many compartments. Before the
spin the players can
bet on such things as the specific number they think the
ball will land on, whether the number will be odd or even, the
color the
ball will land on, etc. The
ball's
final resting
place determines the outcome of the bets.
