Roulette Bets Compared: Hit Probability, Payouts and House Edge
Roulette bets differ by hit probability and payout. A bet that wins more often usually pays less. No standard roulette bet removes the house edge, and a better bet should mean easier to understand or lower volatility, not profitable.

Quick answer
On European roulette, even-money bets have the highest standard hit probability: 18/37, or 48.65%. They are simpler and lower payout, but they are not protective and still have a 2.70% house edge. Single-number bets hit rarely and pay 35:1, but on European roulette they still share the same standard house edge.
Roulette bet reality check
Higher hit probability does not mean better long-term value. On the same standard wheel, most roulette bets trade probability for payout while keeping the same house edge.
What a better roulette bet can and cannot mean
A better bet can mean easier to understand, higher hit probability, lower volatility or a lower house edge by choosing a better wheel variant. It should not mean a bet that wins long-term or protects a bankroll.

| Bet type | Numbers covered | European hit probability | Standard payout | What changes |
|---|---|---|---|---|
| Straight up | 1 | 1/37 = 2.70% | 35:1 | Lowest hit probability, highest standard payout. |
| Split | 2 | 2/37 = 5.41% | 17:1 | More coverage than one number, lower payout. |
| Street | 3 | 3/37 = 8.11% | 11:1 | Covers one row of three numbers. |
| Corner | 4 | 4/37 = 10.81% | 8:1 | Four-number coverage with lower payout than a street. |
| European first four | 4 | 4/37 = 10.81% | 8:1 | Covers 0, 1, 2 and 3 on layouts that offer it. |
| Six line | 6 | 6/37 = 16.22% | 5:1 | Lower hit probability than outside bets, higher payout. |
| Dozen or column | 12 | 12/37 = 32.43% | 2:1 | Middle coverage with the same standard European house edge. |
| Even-money bets | 18 | 18/37 = 48.65% | 1:1 | Highest standard hit probability, still negative EV. |
On American double-zero roulette, standard bet probabilities use 38 pockets instead of 37 and the standard house edge rises to 5.26%. The American top-line bet, 0-00-1-2-3, is a separate warning because it usually pays 6:1 and carries a higher house edge than other American bets.
Coverage vs payout vs house edge
This visual shows the tradeoff behind roulette bets: covering more numbers increases hit frequency but lowers the payout. On a standard European wheel, that tradeoff does not remove the 2.70% house edge.
The bar width represents numbers covered, not expected value. Higher coverage changes volatility, not the built-in wheel edge.
Even-money bets: higher hit probability, not safety
Red/black, odd/even and high/low cover 18 numbers on a European wheel. They hit more often than other standard bet categories, but zero remains a losing outcome on standard European roulette and both zero pockets remain losing outcomes on American roulette.
Inside bets: higher payouts, lower hit probability
Inside bets such as straight-up, split, street and corner bets pay more because they cover fewer numbers. On standard European roulette, the house edge remains 2.70%; the main difference is volatility, not long-term advantage.
American first-five/top-line warning
The American 0-00-1-2-3 bet is different from most standard roulette bets. It usually pays 6:1 and has a higher house edge than other American roulette bets.
Combining bets does not improve expected value
Combining bets can change coverage and payout pattern, but it does not remove the house edge. If a combination covers more numbers, it usually lowers the payout per winning outcome.
Table variant changes every bet
The biggest roulette decision is often the wheel and rule set, not the individual bet. European roulette has one zero, American roulette has 0 and 00, and French rules such as La Partage can reduce the house edge on qualifying even-money bets when available.
When not to play roulette
- Avoid play if you are trying to recover previous losses.
- Avoid play if higher hit probability makes you feel protected.
- Avoid play if a bonus or bet type makes you ignore the house edge.
- Avoid play if your budget is not fixed before the first spin.
Common questions

Is any roulette bet safe?
No roulette bet should be called safe. Even-money bets are simpler and hit more often, but they still lose money in the long run on a standard wheel.
Can combining bets improve my odds?
Combining bets changes coverage and payout pattern. It does not improve expected value or remove the house edge.
