In my system, I can win 2 of any 6 bets (for a winning percentage of .333) in a 6-game series and still attain a profit. Additionally, my wagers, or “Series Amounts,” are predetermined, so there’s no guesswork regarding how much to lay on a particular game. In this system, I'm going to make a Series of up to 6 bets, in the pre-calculated amounts of $11, $22, $44, $66, $88 and $132. I bet 1 or 2 games at a time in the Series, moving up to the next Series Amount after each bet. When you achieve my goal of just 2 total wins, I roll my profits back into my bankroll, and start over at the beginning.
Tonight is the 6th game in the series, hence 13.2 units. I am 1-4 for the 1st five games in this series. Regardless of the outcome of this game, my next two wagers will be 1.1 and 2.2 units.
The system may seem flawed (as it's very possible to only win 1/6 or even 0/6) but if you consistently hit 50-60%, you'll see hitting 33% in 6-game series is profitable long-term.
