#1. Basic Blackjack Strategy

This is known as the best blackjack strategy that aims to get a guaranteed win. If you can use it appropriately, the house edge can be lowered to 0.38% from 0.5%. This strategy will help you to make better decisions based on the cards dealt by the dealer. This strategy uses basic and simple logic to take action.

Split 9 for dealer 2-6,8,9.
Surrender hard 16( except 8s pair) for dealer 9,10 and Ace.
Surrender hard 15 for dealer 10.

#2. Card Counting

This technique helps to determine whether the next dealt card will be beneficial for the player or the croupier/dealer. You must have noticed if you have played in casinos that the punters will suddenly increase the bets that’s because they are keeping track of the cards.

Card counting is an interesting and easy to memorize technique. Once you have learned it, you can easily keep the track of the cards. We suggest you playing online blackjack for free in demo mode to practice the card counting technique. Once you are confident enough, you can give it a real try. 

Now let’s learn how card counting actually works?

There is an equal number of High and low cards in a single deck of cards. The ratio is likely to change when the cards are dealt in few rounds of the game. So. to keep the track of dealt and undealt cards, the tags are assigned to the categorized numbers.

Numbers Tags
A,K, Q, J & 10
  • The counters tag the cards in each player’s hand including the dealer’s hand.
  • If more low cards are dealt that indicates a +ve running count. This situation favours the players. Card counters will bet more.
  • If more high cards are dealt; it indicates the  -ve running count. There are more chances of being blackjacked, this situation favours the dealers.

All you need to do is to calculate the True Count = Running Count/ Undealt Cards.

#3. Martingale Strategy

This strategy works best for live blackjack games. The strategy is based on the theory of French mathematician Paul Pierre Levy. No doubt the risk of losing money is involved as this strategy doesn’t guarantee to win. But if you think you are amongst the luckiest gamblers; martingale may bring the best results for you.

Martingale’s theory is based on the simple theory that a bettor must keep doubling his bets until he wins; no matters if he is on the losing streak. The logic is the assumption that the punter will definitely win after losing consistently.

But let us warn you, this strategy is based merely on an assumption. So it’s totally your call to go for it or leave it. To see whether it works for you or not, start with placing low wagered bets. Be prepared for the losses and know when is the right time to leave the table whether you are winning or losing.

To understand how martingale strategy works. For an instance, let say, 

Bet 1; $1 ; lost

Bet 2; $2 ; lost.

Bet 3; $4 ; lost.

Bet 4; $8; won.

That’s how it works!

#4. Fibonacci System

The best casino strategy to analyze winning odds, developed by an Italian mathematician Leonardo Pisan. It’s less aggressive than the martingale theory. It gives the best results for an even number of bets. This strategy can be applied in any of the casino games like blackjack, baccarat, roulette etc. Let’s see how the Fibonacci series works?

The sequence follows a pattern in infinite series preceded by zero and a 1 and a succeeding number and then numbers in the series are added by adding the two previous numbers. For example: 0,1,5,6,11,17,28……and so on.

To use it in blackjack; ignore the zero and follow the same series pattern i.e. to add the previous two bets for placing a new bet. For example:

Bet #1; $10

Bet #2; $10

Bet #3; $20

Bet #4; $30;

Bet #5; $50——and so on.

The advantage of using this strategy is that it’s easy to memorize and you can easily track by writing down your bet size each time you place the bet. So you can easily track the results; if this strategy is actually working for you or not.

The disadvantage is you have to keep raising the few early bets to get the winning streak. Also, winning is not guaranteed. There is a possibility that you might end up losing a huge amount of money.

#5. Oscar Grind Strategy

Like Martingale strategy, Oscar grind is also a progressive strategy but is far less aggressive. It works in favour of the player minimizing the losses. The bettor doesn’t need to raise the bets chasing the losses unless they are on a winning streak.

This strategy is best for compensating for some of the losses if used wisely. As per the rules of this strategy, you must stop the moment you have earned your profit. Take a look at the 3 basic rules followed by this blackjack strategy:

  • Rule 1: If you win, double your bet.
  • Rule 2: If you lose, Stick to the original bet amount. 
  • Rule 3: Earned the profit? Leave the table now!
