The "en prison" rule in roulette is what it sounds like, but how does it actually work?

[ProGambler]

In some variations of roulette, the "en prison" rule can be used to adjust even-money wagers (such as Red/Black, Odd/Even, or High/Low). If the ball lands on zero, the rule allows players a chance to get their wagers back.

The "en prison" rule in roulette operates as follows:

Place an even-money wager, such as Red or Black, on the roulette wheel.

The "en prison" rule kicks in if the ball lands on zero. Your wager is "imprisoned" on the table for the following spin as opposed to being lost.

Your initial wager is released from prison and is returned to you if the ball lands on the color you bet on in the following spin. You don't receive any further winnings,

but you also don't lose your initial wager.

If the ball doesn't land on your bet's color on the following spin, you lose your initial wager.

Some casinos also offer a variation of the "en prison" rule called "La Partage," which operates similarly. However, in this variation, you automatically lose half of your initial wager if the ball lands on zero, and the other half is returned to you. This rule effectively lowers the house edge for even-money bets, making it a favorable option for some players.

While the "en prison" rule can lower the house edge slightly, it's important to remember that it doesn't guarantee a win or prevent all losses. It's still a game of luck, and outcomes are determined by chance.

The ‘en prison’ rule doubles bets when the ball lands in zero,keeping winnings/losses locked until the next spin.

When the ball lands on zero, the "en prison" rule allows players a second chance to win back their even-money wagers. The "en prison" stake is released and the player receives their initial wager returned without any further rewards if the subsequent spin results in a win for them.
