Positive progression systems involve increasing the size of one’s bet when one wins. The goal of this system is to recoup losses faster so that one can return to a winning position more quickly after a losing streak. Regardless of the specific progression, no such strategy can statistically overcome the casino’s advantage, since the expected value of each allowed bet is negative.<\/p>\n

Whereas the martingale will cause ruin in the event of a long sequence of successive losses, the Labouch\u00e8re system will cause bet size to grow quickly even where a losing sequence is broken by wins. However, over the long run these wins do not compensate for the losses incurred in between. The shape of these systems is typically small but consistent losses followed by occasional big wins.
