Blackjack is a game that may look simple on the outside, but beneath the surface, you’ll find that it’s all about odds and making the correct mathematical decisions. It’s easy to let your intuition take over and base your decisions at the table on that. Blackjack is one of the few casino games which are actually beatable, or at least in theory. This is because unlike most of the other games available on the casino floor, blackjack is a game of dependent trials rather than being based on independent trials. Games like roulette, craps, and slots rely on pure chance for their outcomes since subsequent results are independent of.

How to play blackjack
Understanding the odds offered in any game of blackjack starts with understanding the basics of blackjack gameplay.
Standard 52-card decks are used. Non-face cards have the value of the number printed on them, while jacks, kings and queens are all worth 10, and aces are worth one or 11.
The game has a relatively simple goal: You take cards aiming to get as closeto 21 as you can without going over. Then, you can win in one of two ways: Either the dealer busts by going over 21, or you beat the dealer’s hand. You can also push and will get your bet back if you tie the dealer.
At the start of a game, you and the other players at the table place a bet.
Then, you, the other players at the table and the dealer each receive two cards to start. You and the other players act on your hands before the dealer and can take one of several actions depending on the cards you are dealt. If you hit and go over 21, you lose, regardless of what happens later with the dealer’s hand.
You make these decisions with only one of the dealer’s cards visible. There is no decision if you get dealt an aceand a card worth 10. It means you’ve hit blackjack and get paid 3:2 or 6:5 on your bet, depending on the specific rules of the game and whether the dealer also has blackjack. If the dealer also has blackjack, you’ll likely push depending on the specific rules of the game.
The actions available to you include:
- Standing: Anytime you’re happy with your hand, you can stand. You’ll get no more cards and will get paid 1:1 if either the dealer goes bust or you beat the dealer’s hand.
- Hitting: As long as you’re under 21, you can hit and draw cards to get closer to 21. You can continue hitting until you decide to stand or bust by going over 21.
- Doubling down: You can double down after the first two cards are dealt, depending on the value of your hand and the rules of the game. You double your bet and you’ll get just one more card to go up against the dealer with.
- Splitting: If you’re dealt a pair you can split the two cards into two separatehands. You double your bet and the dealer will give each hand a second card, allowing you to play each one separately. Depending on the cards and the rules of the game, you may even be able to double down after splitting or split again.
- Surrendering: Depending on the rules of the game, you may be able to surrender, or give up your hand. You’ll get half your betback. It’s statistically proven to be a good play when you’ve got 16 against a dealer’s nine, 10 or ace, or 15 against a 10 or ace.
- Buying insurance: If the dealer is showing an ace, you have the option of buying insurance. It costs half of your original bet size and pays 2:1 if the dealer has blackjack, making the hand a push for you. If the dealer doesn’t have blackjack, you lose what you paid for insurance and the hand continues. The house edge on insurance is a whopping 6.7%.
