Andrucci
As with most strategies, it is extremely difficult to say where the Andrucci system actually originated, who came up with it, and how long it has been around. Some sources say it was a group of professional roulette players from Las Vegas known as the Andruccis. Others claim that someone just came up with it and spread it among others.
In any case, the Andrucci strategy has been known for about 50 years. The strategy itself has not yet been able to gain anywhere near the popularity of, for example, Martingale or dβAlembert. This is mainly due to the fact that it basically works only with pure chance. It is not based on any mathematics or bankroll work, and it hardly even works as a roulette system.
