Oscar Greind's sports betting strategy

Oscar Grind's theory was first used in casinos when betting on roulette. Sports fans have since adopted it, and still some use it for games in bookmakers.


The purpose of this technique is to minimize the player’s losses in the long run. The algorithm of actions does not allow players to "lose their heads" in the event of a series of defeats, because the amount of the bet on the loss remains the same. If a series of wins occurs, the bet is increased, which contributes to maximum profit during this period.

The basic rules of Oscar Greind's strategy

  • It is recommended to divide the game pot in such a way that it is enough for 10 equal bets
  • If you lose, the size of the next bet will not change.
  • If you win, the bet for the next step doubles
  • The ratio should be 2.0 or higher
  • The circle ends if the net profit is larger or equal to the size of the bet on the first step

Consider the following example.

Let's say we have a bank of 1000 U.S. Now we need to divide this bank into 10 equal bets, respectively, the rate for the first step will be 100 U.S. For the convenience of conducting mathematical calculations, choose a fixed one. 2.00.

Size of Bet
1100Loss1000 – 100 = 900
2100Win900 + (100 х 2.0) = 1100
3200Loss1100 – 200 = 900
4200Loss900 – 200 = 700
5200Win700 + (200 х 2.00) = 1100
6200Win1100 + (400 х 2.00) = 1900

Based on the table, we can see that after the 6th step (3 losses and 3 wins) the size of the player's pot was 1900 U.S., although he received a profit after the 5th step. Of course, this does not mean that the game always turns out this way: you can of course have more or less wins than in the example. 

When using the Oscar Grind strategy it is very important to stop at certain points. Thus, let us remind you that after losing the bet the size of the next one does not change, and after the winning it doubles. It is important to know that if you win three bets in a row, it is not recommended to increase the size of the bet, as this can lead to the loss of a large amount. If three bets in a row have won, it is worth starting over and returning to the original size of the bet.

Oscar Grind's strategy is available to be used, but it is undesirable to use it in the long term, as odds are used above 2.00, and therefore the probability of getting into a protracted hustle is quite high. In the short term, the strategy can bring profit, but it requires careful analysis.
