Odds of Winning Roulette
Every roulette bet pays out at odds slightly worse than its true probability — that gap is the house edge. Here's your exact chance of winning each bet type, on both wheel variants, plus the roulette wheel odds of winning several spins in a row.
| Bet type | Payout | American odds | European odds |
|---|---|---|---|
| Straight up (single number) | 35:1 | 2.63% | 2.70% |
| Split (two numbers) | 17:1 | 5.26% | 5.41% |
| Street (three numbers, one row) | 11:1 | 7.89% | 8.11% |
| Corner (four numbers) | 8:1 | 10.53% | 10.81% |
| Six line (two rows, six numbers) | 5:1 | 15.79% | 16.22% |
| Dozen (12 numbers) | 2:1 | 31.58% | 32.43% |
| Column (12 numbers) | 2:1 | 31.58% | 32.43% |
| Red or Black | 1:1 | 47.37% | 48.65% |
| Odd or Even | 1:1 | 47.37% | 48.65% |
| High (19-36) or Low (1-18) | 1:1 | 47.37% | 48.65% |
What are your chances of winning roulette?
Your chance of winning a single spin depends entirely on how many pockets your bet covers. An even-money bet (red/black, odd/even, high/low) covers 18 of the 37 or 38 pockets, so it wins 48.6% of spins on a European wheel and 47.4% on an American wheel — the best single-spin chance in the game. A dozen or column covers 12 pockets and wins about 32%. A single number wins just 2.7% (European) or 2.6% (American).
None of these gets you to a coin flip. Even the best roulette bet is under 50% because the zero (and the 00 on the American wheel) belongs to neither red nor black, odd nor even.
Odds of winning multiple spins in a row
Spins are independent, so the odds of winning an even-money bet several times in a row are just the single-spin chance multiplied by itself. This also covers questions like the odds of red landing 5 times in a row — same math, same 18-pocket bet.
| Wins in a row | European wheel | American wheel |
|---|---|---|
| 2 in a row | 23.67% (1 in 4) | 22.44% (1 in 4) |
| 3 in a row | 11.51% (1 in 9) | 10.63% (1 in 9) |
| 4 in a row | 5.60% (1 in 18) | 5.03% (1 in 20) |
| 5 in a row | 2.72% (1 in 37) | 2.38% (1 in 42) |
| 10 in a row | 0.074% (1 in 1347) | 0.057% (1 in 1758) |
A long losing or winning run feels meaningful but changes nothing: the next spin is still 48.6% / 47.4%, exactly as before.
The house edge doesn't change by bet
Notice the win probability changes a lot across bet types, but the house edge doesn't: it's a fixed 5.26% on every American-wheel bet and 2.70% on every European-wheel bet, from a single-number straight-up to a coin-flip red/black wager. Picking a "better odds" bet changes your variance, not your long-run expected loss.
