We don't recommend playing Martingale strategies at Evolution Live Roulette tables, as they can lead to you losing your money quickly. Furthermore, the standard Martingale is limited by the table bet limit of €2,000.
Having said that, there is nothing speaking against you developing your own Roulette strategy to play the game. However, keep in mind that Roulette is a pure game of chance and there is no absolute strategy available that lets you win every time. The probability of winning is the same in every round.
