The En Prison rule in roulette: how does it function?

[ProGambler]

Some casinos provide a version of the European Roulette game known as the En Prison rule. In even-money wagers like red or black, odd or even, or high or low numbers, the rule is frequently applied.

If the ball hits on the zero slot while the En Prison rule is in force, the player has the choice to either withdraw half of their wager or leave it on the table for the following spin. The wager is considered to be "in prison" for the following spin if the player elects to leave it on the table.

The player's initial wager is repaid in full if the ball lands on their preferred color or number on the subsequent spin.

The En Prison rule is an advantageous option for the players as it reduces the house edge of the game. In a standard European Roulette game, the house edge for even-money bets is 2.70%. However, when the En Prison rule is applied, the house edge drops to 1.35%, which means that the player has a better chance of winning.

It is important to note that the En Prison rule only applies to even-money bets, and not to any other type of bets, such as single number bets or column bets. Therefore, players should consider this rule before placing their bets and choose their betting strategy accordingly.

Additionally, the En Prison rule is not always available at all casinos, and even when it is available, different casinos may have different variations of the rule. Therefore, players should check the specific rules of the casino they are playing at to fully understand how the En Prison rule works and how it can impact their game.

I think The En Prison rule is a variation of the European roulette. When a player makes an even-money bet (red/black, odd/even, high/low) and the ball lands on zero, instead of losing the money, the bet is placed in prison or "En Prison." The player's chips are marked with an "En Prison" sign, and they remain on the table for the next spin

The "en prison" rule applies to even-money bets in European and French roulette. If the ball lands on zero, the bet is not lost but "imprisoned" for the next spin. If the bet wins on the next spin, the original stake is returned; if it loses, the bet is forfeited.
