Roulette Variations

There are two types of Roulette tables. The American Roulette table has 38 numbers including 0 and 00. The French or European table has 37 numbers (it doesn’t have the 00). European and Atlantic City Casinos also feature the “En Prison” rule which is favorable to the player. Most European Casinos use the true En Prison rule. Atlantic City 00 wheels use a variation of the En Prison rule called Surrender.

EN PRISON: When En Prison is employed on European Roulette tables, an even money bet (Red, Black, Odd, Even, 1–18, 19–36) that results in a spin of 0 becomes imprisoned. If this imprisoned bet wins on the next spin, the original bet is released and returned to the player.

EN PRISON SURRENDER: An even money bettor only loses half of his bet on a spin of 0 or 00. (Only available on 00 Roulette wheels in Atlantic City.)
