There’s no bulletproof strategy you can use in online casinos to win all the time. Players love using the Martingale strategy and it can be profitable in the short run. Strategies in games of chance don’t work like in poker or blackjack. You can choose to use one in a casino to minimize the risk of losing all the time. However, don’t mistake a roulette Internet casino strategy as a sure way to win – there’s no such thing.
