Casinos love martingale players. It's also a myth that minimums and maximum bets are there to prevent Martingale. Minimums are there because casinos consider bets that are too small to be a waste of time
People just try to martingale with not enough money and think 10 losses in a row won't happen to them.
10 losses in a dice game is not uncommon.
The chance may be very low but when you martingale with small bets, you play a lot of games.
The probability of you busting then becomes very high.
