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.

On the "Come Out" roll, the "Pass Line" bet wins if the shooter rolls a 7 or an 11. The bet loses automatically if the shooter rolls 2, 3 or 12. This is known as "rolling craps". If the shooter rolls 4, 5, 6, 8, 9 or 10 the shooter must roll this same number again (to win) before rolling the number 7. Rolling any of these numbers on the "Come Out" roll is called "establishing the "Point". Any number so rolled is thereafter referred to as the "Point".

This is known as the cancellation system. Pick a series of numbers, say 1,2,3,4,5. Your first bet is the total of the two numbers on the end, or 6 units in this case. If you lose it, you cancel out the 1 and the 5, add the six to the end of the series and bet the 6 and the 2, for a total of eight units bet. Lose that one and you add the eight to the series, cancel the 2 and the six and bet a total of 11 (3+8) and so on. If you win, you proceed to the inside numbers until they are all cancelled out. Again, a loser, but an insidious one.

In this system, you raise your bet one unit if you lose and lower it one unit if you win, which means your winning bets will be higher than your losing bets. It would look like this in practice: 1, lose and go to 2, lose and go to 3, win and drop to 2, lose and go to 3, lose again, bet 4, win, bet 3 ad infinitum. It looks attractive, but the end result is the same: you will eventually lose your money. A ten loss series would have you down 55 units and you would have a helluva time getting out of that hole.
