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 most popular number by far is 7, considered lucky by many people. Another hit is 17 due to its central position on the table. Also, 8 is lucky in many Asian cultures and will also be frequently bet on. As for the unlucky  numbers, you'll rarely see people betting on 13 for obvious reasons.
