At roulette, the odds are constant, and past outcomes have no effect on future play. On a double-zero wheel, the chances of any given number showing up are 1 in 38, every time, no matter what has gone before.
THE PHYSICS OF ROULETTE. Our understanding of the physics behind the movement of the ball and wheel is pretty solid governed by Newton's laws of motion. As the ball slows, gravity takes hold and it falls into one of the numbered compartments. It is predictable when the ball will leave the rim.
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.
Although roulette is a game of chance, you can win big money by playing high-risk, single number bets which pay out better than group or combination bets. Single pockets pay out 35:1 for example, so you can get a decent prize if your single number comes up as the winner.
