Though roulette is a game of a chance, having a strategy can increase your frequency of wins. Some of the best roulette strategies include the Martingale Betting Strategy, the D'Alembert Betting Strategy, the James Bond Betting Strategy, and the All-In Strategy.

Martingale is definitely one of the most widely known and most successful roulette strategies (for some it is the best roulette strategy), and it is very simple to apply. It can be used only for outside bets, those that provide almost 50% chance of winning, and excluding the 0.
