What is Oscar’s Grind?

What is Oscar’s Grind?

Oscar’s Grind is a betting system that aims to grind out small, regular wins. It’s inspired by a cautious gambler named Oscar, who featured in a 1965 book called The Casino Gambler’s Guide. The basic idea is to increase your bet size by 1 unit after each win, and then end each cycle as soon as you generate a small profit.

How Oscar’s Grind Works

Oscar’s Grind is a positive progression system. This approach is designed to generate small profits on a consistent basis. Here’s how it works:

  • Start out by determining your base unit. This should be a small percentage of your bankroll.
  • For example, you might have a $1,000 playing budget, and you may decide to set your base unit at 2%. That means your base unit will be $20.
  • The Oscar’s Grind betting system focuses on cycles. Each cycle ends as soon as you generate a profit of at least 1 unit.
  • Start each cycle by wagering 1 unit on an even money (1:1) bet, such as red/black on the roulette wheel. If your bet wins, you’re left with a profit of 1 unit, and the cycle ends. 
  • If your bet loses, you wager 1 unit again. Keep going until you win. When you win, increase your bet size by a single unit.
  • Keep your bet size the same after each loss, and increase it by 1 unit after each win. When you end up with a profit of at least 1 unit, the cycle ends.
  • You can then begin another cycle by wagering 1 unit again. Keep going for as long as you like.

Example of Oscar’s Grind Roulette Strategy

The Oscar’s Grind betting system is most commonly used on roulette games. Roulette features several 1:1 bets, such as red/black or odd/even, so it’s perfect for this strategy.

Here’s an example of how a session might unfold when following the Oscar’s Grind roulette strategy. The base unit in this example is $10, and each cycle is color coded.

Cycle Bet Size Result Cycle Win/Loss Overall Win/Loss
1 $10 Win $10 $10
2 $10 Loss -$10 $0
  $10 Loss -$20 -$10
  $10 Win -$10 $0
  $20 Win $10 $20
3 $10 Loss -$10 $10
  $10 Win $0 $20
  $20 Loss -$20 $0
  $20 Loss -$40 -$20
  $20 Win -$20 $0
  $30 Win $10 $30
4 $10 Loss -$10 $20
  $10 Loss -$20 $0
  $10 Win -$10 $10
  $20 Loss -$30 -$10
  $20 Loss -$50 -$30
  $20 Win -$30 -$10
  $30 Loss -$60 -$40
  $30 Win -$30 -$10
  $40 Win $10 $30

As you can see, each cycle ends as soon as you earn a profit of at least $10. You then start a new cycle by wagering $10 again. If you lose, the bet size remains the same, and it increases by $10 each time you win during a cycle.

This example highlights four cycles. Overall, you win 10 times and lose 10 times. If you were simply wagering $10 on each spin, you would have broken even. However, by following the Oscar’s Grind system, you’ve actually earned a $30 profit. This clearly highlights the potential benefits of following the Oscar’s Grind roulette strategy.

Pros and Cons of the Oscar’s Grind for Gambling

Pros and Cons of the Oscar’s Grind for Gambling

pros

Pros:

  • A simple strategy: The Oscars Grind betting system is easy to follow. There’s no need for complex equations, and you’re unlikely to wager an incorrect amount. Just keep your bet size the same after a loss, increase it by 1 unit after each win, and end each cycle as soon as you earn a profit.
  • Shouldn’t require a particularly large bankroll: This is a cautious strategy, which doesn’t require an especially large bankroll. You’re unlikely to come up against table limits either, as the system focuses on grinding out small wins, and it doesn’t chase losses aggressively.
  • A winning streak wipes out losses: If you’re in the red, you can quickly wipe out your previous losses by embarking on a winning streak. Oscar’s Grind requires you to increase your bet size after each win, so you will capitalize upon winning streaks. It keeps you in check too, as you end each cycle as soon as you earn a modest profit.
cons

Cons:

  • Not the most exciting strategy: As the name suggests, this system is all about slowly grinding out modest wins. It’s not the most exhilarating approach, especially when compared to aggressive systems like the Martingale, the Fibonacci, or the Reverse Martingale.
  • Only capitalizes on winning streaks when you’re down: Oscar’s Grind only capitalizes upon losing streaks when you’re already in the red. If you win five bets in a row at the start of your session, you’ll be up by 5 units. By contrast, you’d be up by 31 units if you were following the Anti Martingale.
  • Doesn’t inherently chase down losses: You don’t increase your bet size after a loss, so this isn’t the best approach if you’re interested in chasing down losses. If that’s your goal, choose a negative progression system as opposed to a positive progression system like Oscar’s Grind.
When to Use Oscar’s Grind

When to Use Oscar’s Grind

You can use Oscar’s Grind on bets that pay 1:1 if successful. Here are some examples from the most popular online casino games:

  • Roulette: Side bets like red/black, high/low, and odd/even.
  • Baccarat: The player bet.
  • Craps: Pass/don’t pass and come/don’t come bets.

You can also try Oscar’s Grind on blackjack games at online casinos. You’ll be paid out at 1:1 if your hand wins, and blackjack also has a very low house edge if you follow the optimal strategy.

However, it’s not as neat as the examples provided above. Here’s why:

  • You’ll be paid out at 3:2 if you’re dealt a natural (blackjack).
  • You can also double down and split cards.

This makes it harder to successfully implement an Oscar’s Grind blackjack strategy.

Can You Use Oscar’s Grind for Sports Betting?

Can You Use Oscar’s Grind for Sports Betting?

You can technically use Oscar’s Grind for sports betting. However, it’s rare to find sports betting markets that pay 1:1 (+100). Sides and totals at the best online sportsbooks pay 10:11 (-110), so it’s not as neat as playing roulette, baccarat, or craps.

If you plan to use Oscar’s Grind for sports betting, try to use it on markets with odds that are as close to +100 as possible. Ideally, find a site that offers sharp odds, such as BetOnline.

Is the Grind for You?

Is the Grind for You?

Oscar’s Grind is one of many betting systems that you can follow when playing games like roulette, baccarat, and craps. Here are some alternatives to consider:

  • Paroli: This approach requires you to double your bet size after each win. If you win three times in a row, you go back to the start and bet 1 unit again. It’s more aggressive than Oscar’s Grind, but it’s not as aggressive as the Reverse Martingale.
  • Reverse Martingale: Keep doubling your bet size after each win. You need to be prepared to quit while you’re ahead, as a single loss will wipe out your previous wins.
  • Martingale: This is a popular approach, which requires you to double your bet size after each win. The idea is that a single win will wipe out all previous losses. After winning, you go back to betting 1 unit again. It’s a strong approach, but it’s only guaranteed to work if you have unlimited funds and no table limits.
  • D’Alembert: A more cautious alternative to the Martingale, which requires you to increase your bet size by 1 unit after each loss.
  • Fibonacci: Follow the famous Fibonacci sequence: 1-1-2-3-5-8-13-21-34-55-89-144-233-377-610, and so on. Each number highlights how many units you should wager. Start by betting 1 unit. Move one step forward on the sequence each time you lose, and two steps back when you win. 

Oscar’s Grind Works Best With Even Money Odds

Stick to even money bets when using the Oscar’s Grind system. The player bet on a baccarat table has a slender 1.24% house edge, so it’s an excellent option. If you plan to play roulette, try to find a French roulette game, as the French version has the lowest house edge.

Now you know how to use the Oscar’s Grind system, it’s time to put it to the test. Sign up with one of our favorite online casinos to give it a shot.
