Knowledge is power, and when playing online Blackjack, you need to know the game inside and out if you want to have the best chance of beating the Dealer. In this guide, we'll cover the rules, terminology, the many popular versions of Blackjack, go over different strategies, and answer common questions about the game.

Betting Rules: How to Win Online Blackjack

Your first step to mastering Blackjack is knowing how to win.

To beat the Dealer, you need to:

  • have more points than him while not exceeding 21
  • or have 21 points or less when the dealer busts.

Different versions of Blackjack have slightly modified variations of the overall rules, but to beat the Dealer, you'll always need to fulfil one of the above two criteria.

Order of play: After placing your wager on the table, the game will begin. You and the Dealer will both receive two cards. Your two cards will be face-up cards, and the Dealer will have one card face-up, and the other card will be face-down.

Note: The order the cards are dealt can vary between games.

Your goal is now to get as close to 21 as possible. You can take more cards, or end your turn and let the Dealer play his hand. In most games, the Dealer must hit on 16 points or fewer and will stand on 17 points or more.

Hit or Stand: When it's your turn to play, you can choose to hit or stand.

  • Hit - Receive another card from the deck
  • Stand - End your turn and let the dealer act

Card Values: To calculate points, add together the value of all the cards in your hand. Number cards are worth their face value. All picture cards are worth 10 points each, and an Ace holds a value of 1 or 11, depending on which is most beneficial to you.

Double Down: When you have strong odds, such as a hand that totals 9, 10, or 11, you can choose to Double Down. You'll double your bet and receive one last card - automatically ending your turn afterwards.

Split: When you're dealt with matching cards, you'll have the ability to split your cards into two separate hands. Doing so adds another ante bet on the table. Each new hand will receive one card, and then you continue to play with two hands.

Insurance: When the Dealer has an Ace showing, it means he may have a Blackjack hand (An Ace and a face card). The Insurance bet allows you to place a wager half the size of your Ante, and if the Dealer has Blackjack, you'll win a 2:1 payout.

Surrender: If you don't like your chances of winning, you can choose to Surrender. You'll forfeit the round and receive back half of your wager.

Side Bets: Some variations of Blackjack offer side bets, which offer extra betting opportunities based on all the starting face-up cards. The most popular side bet is "player pair" and "21+3".

Multi-Hand: Playing at a Multi-Hand Blackjack table lets you play up to 5 hands per round. Each hand is treated separately and can have a different wager.

All online Blackjack games have an in-depth guide available with information about how to play, the game's rules, odds, payouts and user interface. To access it, click on the "Hamburger" menu button inside the Blackjack game window.

Rule Variations

Online Blackjack is popular around the world, so it's not surprising that people created different variations as the game spread.

  • European Blackjack: This version of the game is played with two decks of cards, and the Dealer only receives his second card after all players have finished their turn.
  • American Blackjack: American Blackjack is played with 6-8 decks, and unlike European Blackjack, the player and Dealer receive all of their cards before anyone decides whether to hit or stand.
  • Spanish 21: If you're looking for a game of Blackjack with a twist, Spanish 21 removes all the '10' cards, which reduces the chances of getting a Blackjack. It also offers a late Surrender, in case you want to forfeit the round.
  • Switch: Ever wanted to play with two hands and switch cards between them? In Blackjack Switch, you can. You'll need to make two equal bets on two hands. What makes this game special is your ability to switch cards between hands.
  • Pontoon: Pontoon is a British variant of Blackjack which replaces the word stand for stick, hit for twist, and double to buy.
  • Double Attack: Just like Spanish 21, all of the '10' cards are removed from the deck, and you can also Double Down.

Odds and Payouts

If you're looking for a game with the lowest house edge, and payouts that are easy to understand, you'll find it in online Blackjack. Most Blackjack games have four simple payouts available:

Blackjack: A hand that has a face card and an Ace is called Blackjack and automatically wins the game. It pays 3:2. If both you and the Dealer have Blackjack, it's considered a tie, and your bet is returned.

Regular Hand: When you beat the Dealer with a non-Blackjack hand, you'll win a 1:1 payout. So if you bet $10, you'll win $10.

Tie: You'll see a tie referred to as Push in Blackjack. When it happens, you'll receive your wager back.

Insurance: You can bet the Dealer has Blackjack by taking Insurance. If you're correct, you'll receive a payout of 2:1.

Winning HandPays$1 Bet Pays
Blackjack3:2$2.5 ($1+$1.5)
Regular Hand1:1$2 ($1+$1)
Insurance2:1$3 ($1+$2)

Online Blackjack Strategy and Tips

As we said before, Blackjack has one of the lowest house edges in any online casino game. Here are some simple strategies you can use to help increase the odds and lower the house edge in your favour.

  • Assume the dealer's face-down card is worth 10 points. There are 4x the number of 10 value cards in one deck (16 of the 52 cards in a deck are worth 10 points). This strategy also applies to your next card.
  • Splitting: It’s an excellent idea to split your hand when you have a pair of Aces. For other hands, use our table below.
Your HandWhen to Split VS. the Dealer
2's, 3's4 through 7
4’s, 5’s, 10’sNever
6’s3 through 6
7’s2 through 7
9’s2 through 6 and 8 or 9
  • Double Down: Doubling Down can be a risky move if you don’t know when the optimal time to use it is. When your hand is a 9, 10, or 11 and the dealer’s showing a 9 is the best time to Double Down. Always remember that Aces can count as 1 or 11.
Your HandDouble if Dealers face-up card is:
93 to 6
102 to 9
112 to 10
A and 22 to 10
A and 25,6
A and 35,6
A and 4,54,5,6
A and 63 to 6
A and 72 to 6
A and 86
  • Surrender: Most Blackjack versions only allow you to surrender at the beginning of your turn. Surrendering when you’re starting hand is 16 while the dealer’s showing a 9, 10 or Ace is the best time to use it.

How to win at Blackjack?

There are two different ways you can win when playing online Blackjack. The first is to have more points than the dealers total without going over 21. The second way is when the dealer goes over 21, while you have 21 or fewer points. In fact, it doesn't matter if you have 3 points in total. If the dealer has 22 or more, and you have 21 or less, you'll win the round.

Is it possible to count cards in online Blackjack?

Counting cards is considered illegal in most land-based casinos. The idea is to track which cards have been shown and to use a scoring system that allows you to try to guess how many 10's are left in the deck(s). But when playing online Blackjack, the digital deck is reshuffled after every round, which makes card counting impossible.
