Roulette Glossary

American Wheel
The American wheel has the numbers 1-36 plus 0 and 00.

This is a bet that one of the black numbers will come up.

Block Betting

A column bet. (French)

Column Bet
The thirty-six numbers on a roulette table are arranged in three columns. A column bet is a bet on all 12 numbers in a column.

Dozen Bet
This is related to the column bet in that it involves betting on twelve numbers. In this bet the player bets on the first third (1-12), the second third (13-24), or the last third (25-36).

En Prison Rule
This rule is rarely employed today. It applies only to outside bets and is offered to a player when 0 or 00 come up. The player can lose half his bet or leave the full bet "in prison". If he chooses the latter, the next spin determines the outcome of his original bet. En Prison is good for players because it reduces the house's advantage.
