Roulette wheel and table layout types: a comprehensive guide

European roulette has 37 pockets, 1 to 36 plus a single zero. American roulette adds a double zero for 38 pockets, which raises the house edge. French roulette uses the single-zero wheel, often with la partage or en prison rules that return part of an even-money bet when zero lands.

• European roulette: 1 to 36 plus a single zero, 37 pockets.
• American roulette: 1 to 36 plus 0 and 00, 38 pockets. The extra pocket increases the house edge.
• French roulette: the single-zero wheel, often with 'la partage' or 'en prison' rules that return part of an even-money bet when zero lands.

The numbers sit in a grid of three columns and twelve rows, with the zero (or zeros) at the top. Around the grid are the outside betting areas: dozens, columns, red or black, odd or even, and 1 to 18 or 19 to 36.

Inside bets cover specific numbers. A straight-up bet on one number pays 35 to 1, a split on two pays 17 to 1, a street on three pays 11 to 1, a corner on four pays 8 to 1, and a six line pays 5 to 1. The fewer numbers you cover, the more it pays and the more often it misses.

• Straight up (one number): 35 to 1.
• Split (two numbers): 17 to 1.
• Street (three numbers): 11 to 1.
• Corner (four numbers): 8 to 1.
• Six line (six numbers): 5 to 1.

Outside bets cover larger groups. Dozens and columns cover twelve numbers and pay 2 to 1, while red or black, odd or even and low or high pay 1 to 1. On every bet, zero is a losing number unless you bet on it directly or the table uses French rules.

• Dozens and columns (twelve numbers): 2 to 1.
• Red or black, odd or even, low or high: 1 to 1.

On every bet, zero is a losing number unless you bet on it directly or the table uses French rules. The payouts stay the same while the odds get worse on a double-zero wheel. The roulette guide covers playing on King Exchange.
