The only principle to The Sure Win Method Betting System is that any even chance will repeat itself and usually quite frequently. Have you ever noticed that red or black nearly always runs in groups? There will be occasions where it will chop sometimes several times but that will not be a problem if you show patience. I believe I have a way to eliminate losses from this.
Your first bet will be on an even chance. If you win, then leave both units on the same bet. If you win a second time, pick up your bet and return to one unit. This is the procedure for every session. If you lose, place the next bet in your progression and try to get a parlay. The progression is shown below. A win and parlay on any step will show a profit. On any profit return to the beginning of the series. When the table is choppy you will sometimes lose several parlays. Remember that each parlay is only 1 bet. My suggestion is not to fight a choppy table or long run of the opposite of your bet but stop after 3 losses and wait until your choice shows again.
While the progression shows 18 steps I have never used more than 9. Decide where your level of comfort is and use it to make your decision as to how long to go. Here is the progression: 1-1-2-2-3-4-5-7-9-12-16-22-29-39-52-69-92-123 A total of 488 units.
Here was a game I played recently: 1L 1W PW 1W PL 1 L 2 L 2 W PL 3 W PW 1 L 1 W PW 1 L 1W PL 2 L 2W PL 3W PW 1 W PW 1 W PW 1 L 1W PW
Profit of 20 units. Keep in mind that you will eventually lose unless you are extremely lucky, but with a little care, it may be years from now. If you wish to try it on Baccarat, Blackjack or Craps I think you will be pleasantly surprised. According to several people, they have been very successful.
