How it works

Every roulette bet pays out as if the zero (and the double zero on an American wheel) did not exist. That gap between the true odds and the payout is the house edge, and it is the same for almost every bet on the table — 2.70% on a European single-zero wheel, 5.26% on an American double-zero wheel.

Because the edge is baked into the payouts, no combination of bets and no betting system can change it. The single worst bet is the American five-number line at 7.89%. The clearest takeaway: always choose a single-zero (European) wheel, where the house edge is nearly half the American one.

edge = 1 − win chance × (payout + 1)

Roulette Odds & Payouts

Roulette is the purest house-edge game: every payout is fixed and the only thing that varies is which numbers a bet covers. This free calculator lays out the payout, true win probability and house edge for every bet on both the European single-zero and American double-zero wheels, with the expected loss on your stake.

Where the house edge comes from

A straight-up number pays 35 to 1. If the wheel had only 36 numbers that would be a fair bet — but the zero (and a second zero on the American wheel) tips it in the casino's favour. The payout ignores the zeros; the odds do not. That gap is the house edge.

On a European wheel it works out to 2.70% on essentially every bet; on an American wheel the extra pocket pushes it to 5.26%. The edge is identical whether you bet a single number or red/black, because every payout is shortened by the same proportion.

Why systems cannot beat it

Since the edge is built into each payout, no staking pattern changes it — Martingale, D'Alembert and the rest only rearrange when you win and lose, never the long-run rate. Every bet on the table carries the same expected loss per unit staked.

The one bet that is worse is the American five-number line (0-00-1-2-3), which pays 6 to 1 for a 7.89% edge — avoid it. The single most valuable decision in roulette is simply to play a single-zero wheel, halving the house edge.

FAQ
What is the house edge in roulette?expand_more

2.70% on a European single-zero wheel and 5.26% on an American double-zero wheel. It applies to almost every bet, because all payouts are shortened by the same proportion.

Does a straight-up number have a worse edge than red/black?expand_more

No. On a given wheel every bet carries the same house edge — only the variance differs. A straight-up wins rarely for a big payout; red/black wins often for a small one.

Which roulette bet is the worst?expand_more

The American five-number bet (0, 00, 1, 2, 3), which pays 6 to 1 and carries a 7.89% house edge — higher than any other bet on either wheel.

Can a betting system beat roulette?expand_more

No. The house edge is fixed in the payouts, so no system changes the long-run expected loss. Systems only alter the pattern of wins and losses, not the math.
