The En Prison Rule

by on October 11, 2012

You won’t see this everywhere, but if you do come across a casino or even just a table playing the En Prison rule you’re in luck.    It actually works in favor of the player and greatly increases the chances of winning particularly if you tend to place a lot of outside bets.  It’s actually very similar to the Surrender rule which you’ll also find explained on this site.

It’s pretty straight forward,  if you make an even money bet such as odd/even or black/red and the ball lands on the zero then you don’t automatically lose your stake.  In this situation the stake is considered ‘En Prison‘ and locked until the next spin of the wheel.

So your stake must remain on the table in the same place, and if it wins on the next spin it is returned to you (but without winnings).   If your bet loses then you lose your stake as normal.  Another zero means that the stake remains on the table and stays there until a non-zero comes up.

So when your stake is En prison (it stays in the same place) and the rule is as follows

  • If your bet wins you get your stake back without winnings.
  • If your bet loses then you lose the stake
  • If another zero is spun the stake stays in position.

It doesn’t sound that great but in fact it does significantly alter the odds you are playing against.  It alters the house edge in a European Casino from 2.7% advantage to a rather low 1.35% although this is obviously only for those outside bets affected by the rule.
