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.

However your long run craps strategy will help improve your play, hence reducing the overall exposure to the house edge making it possible for your craps strategy to work. Maybe they'll work for you or may be they won't - it's gambling after all. Only several of these methods are worth mentioning.
