Oscar’s Grind System is a relatively new betting system, which became known
the introduction of the first computers. In 1965 the system was tested through simulation of 280000 roulette spins on IBM PC 790. The system passed with excellent experience. But it needs to be added that the necessary conditions for this to happen these were unlimited financial resources and “nerves” of the computer.
Principle of the system: Betting on color. Bet € 1 if you win, the series ends and begins again. If you lose, the next time you bet as much as you lost. Once you win, the next bet is increased by one euro. Proceed in this way, while net profit is + 1 EUR. Breaking point cometh when, over a series of losses and start winning again. Then you start to bet as much as you need to win for a whole series 1 euro. There is no need to risk! (see 7. and 8. point of the example).
