Qual jogo vcs acham que tem mais variância para jogar martingale ?

Martingale doesn't work and I'm 100% sure about it. It can work for you for a short period of time very well, but you'll certainly reach a point where you lose all your money.

Even Wikipedia says: "In a casino, the expected value is negative, due to the house's edge. Additionally, as the likelihood of a string of consecutive losses occurs more often than common intuition suggests, martingale strategies can bankrupt a gambler quickly."
