i. think Martingale strategy can be successful in theory, there are a few limitations to consider. Firstly, there is a chance of hitting table limits with consecutive losses and not being able to double the bet any further. Secondly, players need a considerable bankroll to continue doubling their bets after several losses. Lastly, Roulette is still a game of chance, so there is no guarantee of a winning streak even after several losing streaks.
