With this rule in place, which not all casinos offer, (and so therefore is a subject worth looking into when picking an online casino to play roulette at) the House Edge can be brought down to 1.35%. It states that when a 0 (and 00 for the American version) is landed by the roulette ball, all even money bets are not lost, but are rather afforded the opportunity to stay on the board for the next bet, or be taken back by the player. In the long run, this rule can be the deciding factor on whether a player ends in the red or not.

It may not even come into play during a round of roulette. However, the fact that it can be exercised is quite reassuring, made evident by a House Edge reduced by half. Las partage, also called the Surrender rule, governs even money wagers in the same fashion, except that it returns half of the wager, thereby returning a 2.6% House Edge.
