European roulette is played by spinning a small ball on a round wheel. When the wheel stops, the ball comes to rest in one of the numbered slots. Object of the game is to predict which number out of possible 37 the ball will land on. The European Roulette wheel has 37 numbers, including the 0 and 1 to 36. Another name for European roulette is 'Single Zero Roulette'. There are many different ways to place roulette bets. Each bet covers a different set of numbers and has a different distribution. The player has the option to bet on a certain number, a combination of numbers or can choose for the option whether the number will be red or black, even or odd.

The following bet types are possible in European Roulette:

Straight up

You can bet on any number, including 0, by placing the chip on the center of a number.
The payoff is 35 to1.

Split bet

You can bet on 2 numbers by placing a chip on the line that divides the 2 numbers.
The payoff is 17 to 1.

Street bet

You can bet on 3 numbers by placing a chip on the inner left boundary line of the roulette table that is next to the corresponding row of 3 numbers.
The payoff is 11 to 1.

Corner bet

You can bet on 4 numbers by placing chips at the corner where the 4 numbers meet.
The payoff is 8 to 1.

Four bet

You can bet on the numbers 0, 1, 2 and 3 by placing your chip on the inner left boundary line between 0 and 1.
The payoff is 8 to 1.

Line bet

You can bet on 2 street bets by placing your chip on the inner left boundary line where the line dividing the 2 rows intersects it.
The payoff is 5 to 1.

Column bet

There are 3 boxes labeled '2 to 1' at the bottom of a column of numbers. You can place bets for all of these numbers by placing your chip in one of these boxes. If any of the numbers in your column is hit you get paid 2:1; 0 is a losing number.
The payoff is 2 to 1.

Dozen bet

You can bet on a group of 12 numbers by placing your chip in one of the 3 boxes marked '1st 12', '2nd 12' or '3rd 12'. If one of your numbers is hit, you are paid 2 to 1; 0 is a losing number.

Red/Black, Even/Odd, Low/High bets

You can place a bet in one of the boxes on the left, long side of the table that covers half of the roulette table numbers (excluding the 0). Each box covers 18 numbers. You win even money (1 to 1) on all of these bets; 0 is a losing number.

The 'en Prison' rule

Some European casinos offer the 'en Prison' rule. This refers to the Red/Black, Even/Odd and High/Low bets. When the outcome is 0, it’s allowed to leave the bet for another roulette spin. So your bet stays 'en Prison'. If the next spin outcomes in 0 again, then the whole bet is lost, if it’s a hit, the bet is released with no payout.

The 'la Partage' rule

This rule is similar to the 'en Prison' rule, only in this case the player loses half the bet and does not have the option of leaving the bet 'en Prison' for another spin.
