Roulette is primarily a game of luck, as the outcome of each spin is determined by random chance. The layout of the wheel and the distribution of numbers are designed to ensure randomness and make it difficult to predict where the ball will land.

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.
