Different Types Of Online Blackjack Strategy

Blackjack is a game of math probability; you have two cards and you know one of the dealer’s cards. Each deck has 13 potential options:

  • 2
  • 3
  • 4
  • 5
  • 6
  • 7
  • 8
  • 9
  • 10, Jack, Queen, King
  • Ace (1 or 11)

The general probability of your next card is 7.69 percent. However, because 10, Jack, Queen, and King all have the same numerical value the odds of a card with a value of 10 is 30.7 percent of showing up.

Now that you have an idea of the math that goes into basic blackjack strategy follow these guidelines.

  • Always split Aces and 8’s.
  • Double down on 11 always
  • Double down if your first two cards equal 9 or 10 vs. a dealer low card
  • Always hit on a soft 17 or less and always stand on a soft 18 or more. A soft hand contains at least one ace.

Online Blackjack Betting Systems

Online Blackjack strategy isn’t limited to just how to play each hand, there is also betting strategies for you to follow. Here are a few of the popular betting strategies which will help you to take down the dealer:

The Martingale System

The Martingale is a negative progression system, which means you increase your bets when you are losing. In this system, players double their initial bets when they are losing. The system focuses on players with a large bankroll as losing can be crippling. If you are starting with a five-dollar bet and lose eight hands in a row your next bet would be $640 and you would have lost $1,275 in those eight hands. At the same time, one winning hand and you wipe out your previous losses.

The D’Alembert

With the D’Alembert system players must increase your bet one unit if you lose, while lowering your bet by one unit after each win. If a player starts with a five-dollar bet and loses the next bet would be 10 dollars and then 15 dollars. If you win the 15 dollar bet, your next hand is a 10 dollar bet.

Oscar’s Grind

With Oscar’s Grind, you start by betting the minimum unit. If the player wins the hand the follow-up bet raises by one unit only. If a player loses a hand they will not make any changes to their bet. This system was originally designed for craps and the key elements of the system are setting the goal at winning only one betting unit and never going over. Oscar’s Grind helps very disciplined players that want to play for long periods.


Parlay is a progressive betting system in which you reward a win by increasing your bet and drops your bet after a loss. This is also known as a Let it Ride system since you leave your winnings on the table and let them ride on the next hand.


The basics of the 1-3-2-6 betting method are simple. When you win a bet you move onto the next number in the process. If you lose a hand you go back to the beginning of the cycle. Let’s assume your original bet is five dollars and you win four bets in a row, the first bet is five dollars, the second is $15, the third would be $10 and the final bet would be $30. Part of the fun in this online blackjack strategy is it breaks up your bets.
