Roulette: One Game, Three Price Tags
Every bet on a roulette table has the same house edge. The only decision that matters is which wheel you sit at. European costs 2.7%. American costs 5.26%. French with la partage costs 1.35% on even-money bets. Same game. Three prices.
How the Game Works
A wheel with numbered pockets, a ball, a betting layout. You bet on where the ball lands: a single number, a group, a colour, odd or even. The croupier spins, the ball drops, bets settle. That's it, no decisions after the bet, no skill in the outcome. Roulette is pure probability, which is exactly why the variant you choose is the entire strategy.
The Three Variants, Check the Zeros
- European: 37 pockets, one zero. House edge 2.7% on every bet. The standard.
- French: European wheel plus the la partage rule, lose only half your even-money bet when zero hits. House edge on red/black, odd/even: 1.35%. The best deal in roulette.
- American: 38 pockets, zero and double zero. House edge 5.26%, double the European price for the same payouts. Online, there is no reason to ever choose it. Some casinos now offer triple-zero variants at 7.69%. Avoid on principle.
The zero is how the house gets paid. Payouts are calculated as if the zero doesn't exist - 35:1 on a single number that's really 1-in-37. The gap is the margin. The zero pays for the lights.
Bet Types and Payouts
Inside bets: on the numbers themselves. Straight up (one number) pays 35:1. Split (two numbers) 17:1. Street (three) 11:1. Corner (four) 8:1. Six line 5:1. Outside bets: on groups. Red/black, odd/even, high/low pay 1:1. Dozens and columns pay 2:1. Higher payout means lower hit frequency; the edge stays identical. One exception worth knowing: the American "top line" five-number bet carries a 7.89% edge - the single worst bet on any roulette layout.
Systems: The Honest Version
Martingale, Fibonacci, D'Alembert, James Bond, every roulette system rearranges when you lose, never whether. Martingale (double after every loss) produces many small winning sessions and occasional catastrophic ones, because losing streaks are longer than bankrolls and table limits exist precisely to cap the progression. Ten reds in a row happens about once every 784 spins. You'll be there for it eventually.
No system changes the house edge by a single decimal. If one did, the game would be gone from every lobby by Friday, operators monitor game margins weekly, and a beatable game doesn't survive a quarterly review. Play systems for structure and fun if you like them. Just budget them as entertainment, never as method.
Live Roulette: Worth the Seat
Live dealer roulette from studios like Evolution and Pragmatic Play Live is the best way to play online, real wheel, real croupier, ~35–45 spins per hour instead of hundreds on the RNG version. Slower is cheaper. Game-show variants (Lightning Roulette and friends) trade base payouts for multiplier drama: entertaining, but the standard 35:1 straight-up payout drops to 29:1. Know what you're paying for the show. More in our live casino beginner guide.
