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.

There may be individuals who have claimed to make a living from playing roulette, but it's important to approach such claims with skepticism and to consider the long-term statistical probabilities involved in gambling. It's generally not a reliable or sustainable way to make a living.
