Oscar System for Blackjack

The Oscar system, or otherwise known as Oscar’s Grind uses a positive progression style of betting and the aim is to win one unit per cycle, and once the profit is achieved, the cycle ends.  A ‘grinder’ in the gambling world is known as someone who regularly wins small amounts rather than aiming for a jackpot win, and this system rewards these type of players who are patient and are willing to put in hours of continuous gameplay.

The method enables more success if you’re on a streak as it lets you keep your bets low when you are losing and raise them when you are winning, similar to Paroli system, but on the other hand minimizes the loss while having a bad streak, which is its main advantage.

What is Oscar Grind System

As usual with all blackjack systems, the player starts by betting one unit. If you win that hand, then you start again at one unit as you have achieved your aim of a one unit profit. If you fail to win that hand, then you stay at one unit until you win. If you win but haven’t made a profit of one unit yet, you will raise the bet by one unit every time, until you do make a profit of one unit.

Please notice, you must only increase the size of the bet by one unit if you are winning, and as long as it doesn’t give you an overall profit for the cycle of more than one. For example, if you win a 4-unit bet and you are now down to 2 units for the series, you would only bet 3 units to make a profit of one unit for that series.

This gives real meaning to the ‘grinding’ system as you are aiming to win a one unit profit per cycle and no more.


bet result balance profit
$1 loss $99 -$1
$1 loss $98 -$2
$1 loss $97 -$3
$1 loss $96 -$4
$1 win $97 -$3
$2 loss $95 -$5
$2 win $97 -$3
$3 win $100 $0
$1 win $101 +$1


  • Players are able to withstand longer sequences of losses without spending their entire bankroll or hitting table limits
  • It is more than likely you will be able to achieve small profits using this method
  • Even if you are unlucky to have ten consecutive losses, a run of just four wins will get you back on track.


  • It takes a lot of patience to ‘grind’ out a profit and more experienced players may find it hard to win big
  • The system still relies on consecutive wins and may put you far behind if you struggle to hit any consistency

Oscar System Blackjack – Summary

From all the methods we reviewed here on Online Blackjack Explorer, Oscar’s Grind system is definitely the most promising and the only one that can, unlike Martingale, work on a long run (or a long series of short runs). Nevertheless, you should be careful and set a strict budget, since it doesn’t change the fact that the house still has an edge. Also, if you use this system too often, eventually you might be banned by the online casino, so it’s better to divide your play between various online blackjack sites.
