One rule that should be taken into consideration when attempting to beat roulette and increasing your odds is the little known and seldom used En Prison rule. This works in a similar but slightly different way to the surrender rule and is not very common anymore when it comes to roulette, however this does not mean that you can’t find a table either in the real world or online that doesn’t use it.
It works to neutralise the large house edge the casino has in place with the ‘0’ and ’00’ slots, making the odds slightly better for the player. In some cases it can even out the odds entirely, however the En Prison rule only applies when making an even odds bet, for example if you’re betting on red or black, odds or evens, or high and low.
If you are betting on one of these areas and the ball lands on the ‘0’ or ’00’ slots, your bet is held ‘En Prison’ or ‘In Prison’ for the next round. If the ball lands on the section you were betting on in the next round, your money is returned to you, however you will not make any further profit from that bet.
If you are employing a betting strategy that encompasses you betting on an even odds section of the board and the casino has the En Prison rule in place, then it effectively neutralises the effect of the ‘0’ and ’00’ slots on the board, that is as long as you win on the next round.
Although this isn’t a huge way of increasing your odds in roulette, it is a small gain that can be used to work the odds in your favour. However if it’s real money that you’re looking to win from an online casino, my recommendation is still and will always be to use a roulette beating program of the electronic kind.
