The roulette table is the best game for Martingale. This is because roulette offers a simple and easy-to-understand betting system. The Martingale is a good fit for the even-money bets in roulette, such as red or black, odd or even, or high or low numbers. That said, it’s important to remember that no strategy can guarantee a profit, and there is always a risk of losing a large amount of money.
