Roulette is played on a wheel consisting of 37 (European) or 38 (American) slots, each with its own number. The numbers are from 1-36; European wheels will have a single 0 while American wheels will have a single 0 and a double 00. The numbers alternate between pairs of odd numbers with pairs of even numbers, and also between black and red colored slots. The zero number slots are always green. A small ball is rolled in the opposite direction of the spinning wheel and drops into one of the slots when the spinning ends, determining the winning number.
To win at roulette, a player has to correctly predict where the ball will land after each spin of the wheel. Players are paid out according to the location of their betting chips on the roulette table. Basic bets are payed out 1:1 while numbered bets are paid out as much as 35:1.
