How to Play Blackjack

Blackjack is a comparing game between the player and the dealer. Your goal is to finish closer to 21 than the dealer without going over 21. The rules are simple, but the decisions become interesting because the dealer upcard changes the best move.

The objective

You are not trying to reach exactly 21 every hand. You are trying to beat the dealer by finishing with a better total without busting. If your total goes over 21, that hand busts.

A natural blackjack is an ace plus a ten-value card as the first two cards. It is the strongest starting result and is handled separately from ordinary 21 totals.

Card values and totals

Cards 2 through 10 count as their printed value. Jacks, queens, and kings count as 10. Aces count as either 1 or 11, depending on which value helps the hand without busting.

A hand without a flexible ace is called a hard hand. A hand where the ace can still count as 11 is called a soft hand. A pair is two cards of the same rank and may be eligible to split.

Player actions

Hit means take another card. Stand means keep your current total. Double means increase the practice unit and take one final card. Split means separate a pair into two hands.

Those actions are not guesses. Basic strategy tells you when each action is strongest by comparing your hand type and total to the dealer upcard.

Dealer rules

The dealer acts after the player. In most blackjack games, the dealer must draw until reaching at least 17. Because the dealer follows fixed rules, player strategy can be organized around the visible dealer upcard.

Weak dealer upcards such as 4, 5, and 6 create more chances for the dealer to bust. Strong upcards such as 10 and ace put more pressure on the player to improve.

Frequently asked questions

What number does the dealer stop on?

The dealer usually draws until reaching at least 17. Some rules require the dealer to hit soft 17, which can slightly change strategy.

What is a bust in blackjack?

A bust is any hand total over 21. If the player busts, that hand loses immediately in a real game.

Is blackjack only luck?

Short-term results involve luck, but decision quality matters. Basic strategy reduces avoidable mistakes by choosing the best long-run action for each hand.
