Honestly, the woman who helped me was nice, even though she sounded very fake. Said she was going to call me back by a certain time and never did. I had to call for her to tel me that they couldn't switch the show. I got beautiful, I already saw it. It's not good for locals, their options suck and they charge more to cross off more shows. Nice idea, but horribly executed
Some French tables will employ rules that generally help out the players. The "La Partage" and "En Prison" rules apply to outside even money bets like odds or even, black or red and low or high; they also apply when the ball lands in the zero slot. They are similar in the sense that players only lose half of their bet, but players cannot leave their bet on the table for another spin with the La Partage rule. If a player loses, they can collect half their bet in the En Prison rule, or leave half their bet on the table for the next spin with the La Partage rule.
Even if there isn't a betting limit, and if you have an infinite credit limit, it still doesn't really work, it just doesn't really fail either. If the martingale strategy is continued indefinitely and without regard to betting limits, your bankroll will hit arbitrarily high positive and negative values. The expected value is still negative, but the variation is so high that it your bankroll won't stay either negative or positive.
