Bet that the decision (pass or don't pass) before the last one will repeat. This is identical to betting that the next decision will be the opposite of a single decision or the same as the previous multiple decisions. The progression is an up as you win parlay to 5 units… 1-2-4-5, when you win the 4 unit bet you have 8 units on the table. Remove 3 units (which is a 2 unit profit and your original 1 unit) and then you leave the 5 unit bet on until it loses. When it loses you then start over at the 1 unit level. Treat all decisions the same, even if they are naturals or craps or bar-12 (or bar-2). Table selection is very important. You only play on tables that have between 3 and 6 other players besides you.

The time that you lose the most with My Parlay Method is when there are streaks of doubles. I have found a way to win when that happens! Start out playing the regular way, betting on the decision before the last one. The exception is when it comes out with a double followed by a single. Normally you would bet the opposite of the single will come out.
In this specific situation (which happens fairly often) you will bet that the single will repeat. If you win that bet, then the next bet is that the sets of doubles will continue (bet the opposite of the last double instead of the same). As long as the sets of doubles continue, keep betting this way. As soon as you lose a bet then revert back to the original method.
