Don't seek ways to try to "beat" roulette or you will regret it. Sometimes you WILL win, but in the long run, there is no way around it - you WILL lose more than you will win. This is an undeniable, inevitable fact! And cancel all your credit cards as soon as you can. Go doing something else, go to play chess.
I disagree, not about cancelling your credit cards if you have too many, but that you can't win with Roulette. You just need to not be impatient and greedy. Greed and inpatience make you a loser. Casinos just love you if you are either of those two or both which applies to most people.
Get out as soon as you are ahead, 95% of gamblers who are ahead at some point continue to play and end up losing. Be part of the 5%.
