The Even Bet in Roulette

Roulette School

Roulette offers a type of bet that is called the even bet. This is a type of outside bet that provides a payment of 1-to-1 and as such is considered an even-money bet. From the player’s perspective the even bet is one of the best bets in roulette and this article will explain why this is so.

What is the Even Bet?

Roulette offers players many different bets to choose from. Each of the bets offered has its own probability of occurring and different payouts offered for winning the bet. There are high risk bets and low risk bets so each player can choose the level of risk they are comfortable with.

The European roulette wheel has 37 numbered slots with numbers ranging from 1 to 36 and the number zero. The American roulette wheel has 38 numbered slots with numbers ranging from 1 to 36 and the number zero and double zero.

On both roulette wheels the numbers 1 to 36 are split equally with 18 even numbers and 18 odd numbers. Zero and double zero do not count as either an even or an odd number.

Players can make bets by predicting whether the roulette ball will land on an even number or an odd number. Making a correct prediction will award the player a payout of 1-to-1 for their bet.

Why the Even Bet is considered an Outside Bet?

The bets that players can make when playing roulette are split into two main groups; inside bets and outside bets.

Inside bets are wagers made on a single number or a very small group of adjacent numbers. They carry a low probability of generating a win but offer very high payouts for wins as a way of compensating for the low probability.

Outside bets are wagers made on large groups of numbers. They carry a high probability of generating a win but offer lower payouts to compensate for the high probability.

The even bet falls under the umbrella of outside bets because in a single bet the player covers almost half of the numbers available on the roulette wheel.

The Probability

Think for a second that the roulette wheel only had 36 numbers, ranging from 1 to 36, and did not have the zero and double zero slots. In such a case half the numbers on the wheel would be even numbers and half the numbers would be odd numbers.

If you were to make the even bet under these circumstances the probability of winning the even bet would have been 18/36 = 0.5 which is a probability of 50%.

However the roulette wheel is not comprised of only 36 numbers. In European roulette the number zero is also present on the wheel so the probability of winning the even bet needs to be calculated as 18/37 = 48.64%. This means that the odds of winning the even bet are 1.01-to-1 with a payout of 1-to-1.

In American roulette there are two numbered slots in addition to the 36 numbers. These slots are for the numbers zero and double zero and they change the probability of winning the even bet. The probability of winning is calculated as 18/38 = 0.4736 which places the odds for a win at 47.36%.

The payout for a winning even bet is the same in American roulette as in European roulette but the true odds are 1.11-to-1. As you can see European roulette gives better chances of winning the even bet so if you have the choice between the two types of roulette, we recommend you opt for European.

The “En Prison” Rule

When you play French roulette and also in some European roulette games you have the option of using the “En Prison” rule. “En Prison” means “in prison” in French and it’s a rule that allows you to imprison your even bet for the next round of play if in this round of play the outcome of the spin was zero.

The “En Prison” rule basically gives you two spins for the price of one when making even-money bets and it significantly lowers the house edge on such bets.

In Conclusion

The even bet is one of the best bets offered in roulette. It is true that it does not offer a huge payout but that is reasonable considering the low level of risk attached to it.

Players that focus their roulette playing on making outside bets such as the even bet, have a better chance of making their bankroll last longer.
