Roulette Odds for American and European Roulette
The article Roulette Odds aims at presenting likelihood of ball landing on a given number, or a cluster of numbers. It is not that hard to calculate the roulette probabilities but it may be of use if you study this table and commit it to memory.
American Roulette Odds
The American Roulette wheel has a zero, a double-zero and 36 regular numbers. Hence, you have 38 possible spaces on which the ball may land. When you bet on a single number, you have a 1/38 chance of winning. Over time, you will win 1 out of every 38 spins. Take a look at the probabilities for every possible outcome illustrated in the table below.
| Bets | Payout | Probability |
|---|---|---|
| Red | 1 to 1 | 46.37% |
| Black | 1 to 1 | 46.37% |
| Even | 1 to 1 | 46.37% |
| Odd | 1 to 1 | 46.37% |
| 1 to 18 | 1 to 1 | 46.37% |
| 19 to 36 | 1 to 1 | 46.37% |
| 1 to 12 | 2 to 1 | 31.58% |
| 13 to 24 | 2 to 1 | 31.58% |
| 25 to 36 | 2 to 1 | 31.58% |

| 0, 00, 1, 2, 3 combo | 6 to 1 | 13.16% |
Remember that these are the American Roulette odds. The European table does not have the double zero and due to this fact is much more advantageous to the player.
European Roulette Probabilities
In European roulette there is not a “00” hole, giving you an advantage and a better chance of winning. For example, for every $1 you bet on European Roulette, you could expect to get back 97.37 cents over the long run ($1 minus the house edge of 2.63%, or 2.63 cents). Playing American roulette, you can expect to get back only 94.74 cents.
