Oscar's Grind system

Although a modern gambling system, the exact origins of the Grind system have been lost. It is first described in 1965, attributed to a gambler named - believe it or not! - Oscar.

The Grind gambling system is simple. You bet in cycles, and the aim is to make just 1 unit profit per cycle. Once this profit is achieved, the cycle stops. It doesn't try to make more than 1 unit and even stops itself from doing so.

How does the Oscar's Grind system work?

The Grind system works as follows: 

You bet 1 unit. 

If you win, the cycle is ended and you start again. 

If you lose, a new cycle starts.

In a betting cycle:

When you're losing, keep the bet the same.

When winning, increase the size of the bet by 1 - unless that would give an overall profit for the cycle of more than 1.

An illustration

For example, in the Alternating loss test (Lose, Lose, Win, Lose, Win, Win, Lose, Win, Lose, Lose, Win, Lose), after 5 bets, you're down 1 unit and the bet size is 2. The system says to raise the bet when you're winning, but raising the bet size to 3 would give an overall profit of 2. To make sure we don't win more than 1 unit for the cycle, we have to keep the bet size at 2.

Grind it out

This last rule gives rise to the most confusion when first using the Grind gambling system. But it's important to remember that it is seeking to literally grind out a 1 unit profit and no more.

This makes it suitable for small consistent wins in games like Roulette.
