Roulette is a casino and gambling game named after the French word meaning "small wheel". In the game, players may choose to place bets on either a number, a range of numbers, the color 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. The ball eventually falls on to the wheel and into one of 38 colored and numbered pockets on the wheel

Types of bets

Inside bets

• Straight-up: a single number bet. The chip is placed entirely on the middle of a number square.
• Split: a bet on two adjoining numbers, either on the vertical or horizontal (as in 14-17 or 8-9). The chip is placed on the line between these numbers.
• Street: a bet on three numbers on a single horizontal line. The chip is placed on the edge of the line of a number at the end of the line (either the left or the right, depending on the layout).
• Corner (or square): a bet on four numbers in a square layout (as in 11-12-14-15). The chip is placed at the horizontal and vertical intersection of the lines between the four numbers.
• Six Line: a bet on two adjoining streets, with the chip placed at the corresponding intersection, as if in between where two street bets would be placed.
• Trio: a bet on the intersecting point between 0, 1 and 2, or 00, 2 and 3.

Outside bets

Outside bets typically have smaller payouts with better odds at winning.

• 1 to 18: a bet on one of the first low eighteen numbers coming up.
• 19 to 36: a bet on one of the last high eighteen numbers coming up.
• Red or Black: a bet on which color the roulette wheel will show.
• Even or Odd: a bet on an even or odd number.
• Dozen Bets: a bet on the first (1-12), second (13-24), or third group (25-36) of twelve numbers.
• Column Bets: a bet on all 12 numbers on any of the three vertical lines (such as 1-4-7-10 on down to 34). The chip is placed on the space below the final number in this string.
