No system can overcome a house edge. You can minimize your losses by playing wisely on games of skill, but systems make no difference to games of pure chance like roulette. Those who use systems in roulette are fooling themselves. Don’t believe otherwise. Expect to lose in the long run – if not right from the start! Remember the basic rule – the more you play the more likely you are to lose.

This is a very simple craps strategy. You have placed your online craps bet. Each dice roll you win your wager you will increase the current bet by that initial one. Every time you lose you'll bet the current amount minus the initial one. As long as you are winning you will continue to raise your bets and when you start losing you'll bet the same bets but in a descending order.
