In the game Gadget Grip

In the game, players may choose to place bets on either a single number
or 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 (in
French/European roulette) or 38 (in American roulette) colored and
numbered pockets on the wheel.
