After two consecutive single zeros are spun, it is more likely that the player will lose his/her bet.The Uptown section of Atlantic City, showing Showboat Atlantic City and The Taj Mahal casino, the latter of which closed in 2016 and reopened in 2018 as the Hard Rock Hotel and Casino Atlantic City in 2018. One would certainly say it is best for the bet to win, but such a scenario is quite rare. In case a single zero is followed by another single zero during the next spin, the player will have three options – to lose the bet, to win the bet or to leave the bet for additional wheel spins. There are a few casinos, where the rule is even more complicated. This rule, in fact, provides the player with a second chance, if he/she has lost due to the single zero on the wheel. In case red does not win, the entire 120-dollar bet will be surrendered to the house. At the next spin, in case red wins, the original 120-dollar bet will be recovered to the player. The winning number, however, is 0 (green) and the bet will be put in prison during the following wheel spin. Say, an original bet of $120 is placed on red. But in case the bet loses, it will be surrendered to the house. In case the outside bet wins, the player will be allowed to keep the original wager. By saying ”imprisoned” we mean that the player's chips will be left standing on the table during the next spin. If a player places an even-money outside bet, but the single zero turns out to win, he/she will need to make a choice between two options – to lose 50% of his/her bet, or to let the entire bet be ”imprisoned” during the next ball spin. However, it is this circumstance that makes the ”en prison” rule not so easy to find both among land-based and online casinos in Europe. By applying the ”en prison” rule, the house edge is reduced even further, to 1.35%, thus, the chance for a player to profit is additionally bolstered. As noted earlier, when playing French roulette, one is faced with a 2.703% advantage for the house, or a greater chance of winning compared to the American roulette, for instance. As a rule, it is valid for the French roulette wheel only.
