Roulette chance works on the simple rule of single events with set odds. European roulette wheel has 37 spots (numbers 0-36), each number has the same chance to show up on every spin, not changed by past spins. Chances to land on any one number is 1/37 (2.7%).
Common Betting Chances
Outside Bets
Red/Black betting gives a 18/37 (48.6%) chance of winning, the same as for Even/Odd and High/Low bets. These outside bets are top picks for their near-even money odds. Column bets and dozen bets that cover 12 numbers each, give a 32.4% chance of winning.
Inside Bets
Split bets, covering two close numbers, have a 2/37 chance. Corner bets (four numbers) show a 4/37 chance, while street bets (three numbers) have a 3/37 chance. These inside bets offer bigger pays but come with higher risks due to lower win chances.
House Edge and Fixed Math
The house edge on a European roulette wheel stays at 2.7%, from the wheel’s odds setup. This edge can’t be changed by betting plans or pattern spotting. Understanding these set chances is key for smart play, as they set the math base that rules all roulette results.

European roulette keeps a 2.7% house edge through its single-zero wheel setup. This means a loss of $2.70 per $100 bet over a long time. The house gets this edge by paying 35:1 on winning single number bets against real odds of 36:1, with the single zero creating this money gap.
American roulette has a clearly higher 5.26% house edge due to its extra double-zero spot. Players lose double, $5.26 per $100 bet, compared to European roulette. This bigger house advantage is the same for all bet kinds – from single numbers to even/odd bets.

- Max cap of 3% total money pot
- Back to start bet after cap is hit
