How to Play Blackjack: Rules, Basic Strategy, and Side Bets

The goal of blackjack is simple: build a hand with a point total closer to 21 than the dealer’s hand, without going over. While the premise is straightforward, mastering the game requires understanding exactly when to hit, stand, double down, or split based on mathematical probability.

Our comprehensive guide covers everything from basic card values and dealer rules to the most effective blackjack basic strategy chart, giving you the best possible chance to reduce the house edge at the tables.

Blackjack Card Values

Before you place a bet, you need to know how to calculate your hand’s total. Suits (hearts, spades, clubs, diamonds) have no meaning in blackjack. Only the numerical value matters:

• Numbered Cards (2–10): Worth their face value.
• Face Cards (Jack, Queen, King): Each is worth 10 points.
• Aces: Can be worth either 1 or 11 points. An Ace and a 6 is known as a “Soft 17” (because it can be 7 or 17). If you draw a 10 to that hand, the Ace simply reverts to a 1, giving you a “Hard 17”.

Basic Blackjack Rules & Dealer Rules

A standard round of blackjack begins with players placing their bets. The dealer then deals two cards to each player face-up, and two cards to themselves (one face-up, one face-down). Here is how the payouts and rules govern the game:

• Natural Blackjack: If your first two cards are an Ace and a 10-value card, you have a “Blackjack.” This typically pays out at 3:2 immediately, unless the dealer also has a Blackjack (which results in a “push” or tie, returning your stake).
• Regular Wins: If you beat the dealer’s total without going over 21, you are paid 1:1 (even money).
• Busting: If your total exceeds 21, you “bust” and immediately lose your bet, regardless of what the dealer eventually draws.
• Dealer Rules: Unlike players, dealers have no free will. They must follow strict house rules. In most casinos, the dealer must hit on 16 or below and must stand on 17 through 21. Some tables require the dealer to hit on a “Soft 17,” which slightly increases the house edge.

Player Options: Your Moves at the Table

Once your first two cards are dealt, you have several choices to make based on your hand and the dealer’s visible “upcard.”

Hit

Request an additional card to get closer to 21. You can hit as many times as you like until you either choose to stop or bust.

Stand

Decline any further cards and end your turn. You do this when you are satisfied with your total or when you believe the dealer’s upcard will cause them to bust.

Split

If you are dealt two cards of the same value (e.g., two 8s), you can split them into two separate hands. You must place an additional bet equal to your original wager. You then play each hand independently.

Double Down

You can choose to double your original bet in exchange for receiving exactly one more card. This is highly recommended when you have a total of 10 or 11, and the dealer is showing a weak card (like a 5 or 6).

Surrender

Not offered at all tables, “late surrender” allows you to forfeit half of your bet and end the hand immediately after the dealer checks for blackjack. It is mathematically the right play on terrible hands (like a Hard 16 vs a Dealer 10).

Blackjack Basic Strategy Chart

Basic strategy is the mathematically optimal way to play every possible hand of blackjack against every possible dealer upcard. Using this chart reduces the house edge to around 0.5%. Memorize it or keep it open while playing online.

Blackjack Side Bets Explained

Many online casinos offer optional side bets. While they offer exciting, high-value payouts, they mathematically carry a much higher house edge than the main game.

• Insurance: If the dealer’s upcard is an Ace, you can place a side bet equal to half your original stake. If the dealer has a 10 underneath for a Blackjack, the insurance pays 2:1, protecting you from loss. However, statistically, taking insurance is a bad bet and increases the house edge. Never take it.
• Perfect Pairs: You bet on whether your first two cards will be a pair. Payouts vary depending on whether it’s a Mixed Pair (e.g., Red 5, Black 5), Colored Pair (e.g., Hearts 5, Diamonds 5), or Perfect Pair (two exact identical cards, like two Jack of Spades).
• 21+3: This side bet combines your two cards and the dealer’s upcard to form a three-card poker hand. You win payouts for landing a Flush, Straight, Three of a Kind, Straight Flush, or Suited Three of a Kind.
