This idea intrigues me cyclically. I recently was at the casino and saw a man playing at another table. While everyone is betting on the numbers, he gambled dozens. It caught my attention because he added a chip on each spin. mmm it is a unintelligent system which pays 2-1, he is increasing more than what is required.
The truth is that when he won back top bets he earned more, up a chip of it at a time makes more money. I saw no rhyme or reason to the dozens he chose. It was not the most sleepy. Nor was always the last dozen spun. At times he won but continued to rise only to drop back after a hit.
It was earning well, perhaps thinking he had the ultimate winner with that over-betting system. It recalled me this question of systems may expire per person.
