You sit down, buy chips, and the dealer starts a hand
Blackjack is a comparing card game. You are not playing against the other people at the table, and their hands do not affect yours. Every player at the table is playing their own hand against the dealer's hand only. The objective is to finish with a hand total closer to 21 than the dealer's without going over 21. If your total exceeds 21, you lose immediately, no matter what the dealer does next. That single rule drives almost every decision you will make.
The game moves in a fixed sequence. You buy in by placing cash on the table, never into the dealer's hand; the dealer exchanges it for chips. You place a bet in the marked circle in front of you. The dealer gives each player two cards face up, and takes two cards, one face up and one face down. From there, each player acts in turn before the dealer plays. When every player has finished, the dealer reveals the face-down card and plays according to a fixed rule that does not change based on what players did.
Card values and what a total means
Numbered cards count as their printed value. Face cards count as ten. An ace counts as either one or eleven, whichever gives you the better hand at that moment. A hand with an ace counted as eleven is called a soft hand, because the total can drop by ten if you draw a card that would otherwise bust. A hand without an ace, or with an ace forced to count as one, is a hard hand.
A two-card total of 21 made from an ace and a ten-value card is a blackjack. It is the strongest starting hand and is settled differently from any other 21 you might reach by drawing cards. A blackjack normally pays at better odds than a standard win, but the exact payout is printed on the table and varies between venues.
The decisions you make, in order
When the dealer points to you, you signal a decision. The main options are these:
- Stand: keep your current total and end your turn. You signal by waving a hand horizontally.
- Hit: take another card. You signal by tapping the table. You may keep hitting until you stand or bust.
- Double down: place an additional wager equal to your original bet and receive exactly one more card. You cannot hit again after doubling.
- Split: if your first two cards are a pair, you may separate them into two hands, each with its own bet equal to the original, and play each hand independently.
- Surrender: where offered, you may forfeit the hand and lose half your bet rather than play it out. Not every table offers surrender.
Each decision changes the expected rate of loss on the hand. The correct choice depends on your total and the dealer's visible card. Published strategy charts exist for exactly this reason, but they derive from the specific rule set in use. The number of decks, whether the dealer stands or hits on a soft 17, whether doubling after splitting is allowed, and whether surrender exists all change the correct play. A chart written for one rule set can be wrong at a table with different rules.
How the dealer plays and how the hand settles
After all players have acted, the dealer turns over the face-down card. The dealer has no choices. The dealer must draw cards until reaching a total of at least 17, and must stop at 17 or higher. At most tables the dealer stands on all 17s, including a soft 17; at some tables the dealer hits a soft 17. The rule is printed on the table layout, and it matters to your expected return.
If the dealer busts, every player who has not already busted wins. If the dealer does not bust, each remaining hand is compared to the dealer's total. A higher total wins. An equal total is a push, and your bet is returned. A dealer blackjack beats any player total except a player blackjack, which pushes.
The procedure for a win is simple: the dealer pays your winning bet by placing chips next to it. You do not touch the original bet or the winnings until the dealer has finished paying the whole table. When the hand is fully settled, the dealer collects the cards and the next round begins.
Main bet types and why the edge differs
The standard bet is the one placed in the circle before the cards are dealt. It pays even money on a normal win, and a blackjack usually pays at a higher rate, commonly shown on the table. But blackjack tables often carry side bets as well, and the difference in house edge between the main bet and a side bet is usually large.
| Bet | What it is | How the house edge behaves |
|---|---|---|
| Main bet | Your wager on your hand beating the dealer's without busting | The lowest-edge bet on the table; the exact edge depends on the rule set and on whether you follow the correct strategy for that rule set |
| Insurance | A side bet offered when the dealer's upcard is an ace, wagering that the dealer has a blackjack | Carries a materially higher edge than the main bet; it is a separate wager settled on its own |
| Pair or match side bets | Wagers on your first two cards forming a pair, a suited pair, or another specified combination | Usually a much higher edge than the main bet, because the payout is fixed while the odds of the event are low |
| Progressive side bet | A side wager feeding a growing jackpot, typically paid on rare multi-card combinations | The contribution to the jackpot is taken out of the bet's return, so the base edge is higher; the jackpot itself is rare |
The main bet is the one where your decisions change the expected rate of loss. Side bets are settled purely on the cards dealt; no decision after placing the bet changes anything. That is why the edge on a side bet stays high no matter how well you play the main hand.
What strategy charts do
A basic-strategy chart tells you the decision that minimises expected loss for every combination of your total and the dealer's upcard. It does not promise a win, and it does not remove the house edge. It reduces the edge to the lowest level the rule set allows by removing avoidable mistakes. A player who hits when the chart says stand is not unlucky; they are paying a higher edge than the table requires.
Because the chart depends on the exact rules, the first thing to check before using one is the table's posted rule set. The number of decks in play, the dealer's soft-17 rule, whether doubling after splitting is allowed, and whether surrender exists all shift specific decisions. If you do not know the rule set, you cannot know which chart applies.
Procedural mistakes that cost new players
The first mistake is touching the cards. In most shoe-dealt games, players never touch the cards at all; in pitch games where cards are dealt face down, you hold them with one hand above the table. Touching your bet after the cards are dealt is also a serious error, because it looks like an attempt to alter the wager. The dealer will stop you.
The second mistake is signalling unclearly. A tap that the dealer reads as a hit when you meant to stand, or a wave that is too small to see, changes the hand. The cards decide the outcome, but your signal decides which cards you receive. Learn the hand signals before you sit down, and make them large enough for the camera and the dealer to see.
The third mistake is placing a side bet because the main hand is going well. The main bet and every side bet are independent wagers with independent edges. A run of winning hands does not change the edge on the insurance bet or the pair bet. The side bet is not a reward for playing well; it is a separate game with a worse rate of loss.
FAQ
Does a blackjack always pay 3 to 2?
No. The payout for a blackjack is set by the table and is printed on the layout or a sign at the table. Some tables pay less than 3 to 2, and the difference changes the house edge on the main bet. Check the posted payout before you sit down, because two tables in the same venue can offer different blackjack payouts.
Should I ever take insurance?
Insurance is a separate bet on the dealer having a blackjack, and it carries a higher house edge than the main bet. The decision does not affect your original hand. Whatever you decide on insurance, the main hand is settled on its own. The lower-edge choice is to decline it, but the decision is yours at the table.
Can I count cards to know what is left in the deck?
Counting cards is a method of tracking the ratio of high to low cards remaining, and it is not illegal, but venues may refuse service to anyone they believe is doing it and may ask them to leave. It also does not remove the house edge; it shifts the edge slightly in the player's favour only under specific conditions and with substantial bankroll and discipline. Most players at a recreational table are not counting, and the game does not require it.
