What is the most successful roulette strategy? While there is no strategy that can guarantee a profit in the long run when playing roulette, the Martingale betting system is often regarded as the most successful strategy. It is easy to use and can provide good returns.
The real trick to roulette is to get lucky, then quit while you're ahead. Every spin has a 1 in 37 (for European) or 1 in 38 (for American) chance of landing in a given pocket.
