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.

I think the en prison" rule gives the player another opportunity to win back their bet without having to place another wager. However, it's important to remember that the house still has the edge in roulette and incorporating en prison into a betting strategy won't necessarily guarantee success in the long run.

The "en prison" rule means that if an even-money bet lands on zero, the bet is held for the next spin rather than lost immediately. If the next spin wins, the player's original bet is returned without additional winnings. This rule helps reduce the house edge in European and French roulette.

I think it is important to note that this rule is not always available in all casinos or roulette games. Some variations of roulette may have different rules or strategies, and players should always be aware of the particular rules and odds of the game they are playing

The player gets their original stake back without any further winnings if the imprisoned bet wins on the next spin.
But if the next spin doesn't produce a win for the imprisoned bet—that is, if another zero appears—the entire imprisoned bet fails.
