Differences in Rules There are a few differences in rules between the different roulette versions as well. One major difference I want you to be aware of what happens when the ball falls on zero. In the American Roulette rules, when zero comes up all outside bets are considered losers for PGSGAME168 the players. This means that no matter if you bet on odd, even, red, black, high, or low, you lost. This is not necessarily true in French Roulette. Instead, one of two rules is applied. The first of these is called “En Prison,” which means “in jail.” In this instance, the bets are not lost, and they stay on the table for the next spin. If zero comes up a second straight time, then you lose. However, if any other number appears, then winning or losing depends upon whatever number, color, or other choice you bet on. The second option is called “La Partage.” In this rule, you lose half of what you bet. The remainder is returned to you for you to use on another wager or to keep if you choose.
