Blackjack FAQ

Blackjack is a card game where players compete against the dealer, not each other. The goal is to have a hand value closer to 21 than the dealer without exceeding 21. Number cards are worth their face value, face cards (Jack, Queen, King) are worth 10, and Aces can be worth 1 or 11.

Basic gameplay:

• Each player receives two cards face up; the dealer gets one face up and one face down
• Players can Hit (take another card), Stand (keep current hand), Double Down (double bet, take one card), or Split (if two same-value cards, split into two hands)
• The dealer must hit on 16 and stand on 17
• If your hand exceeds 21, you bust and lose immediately
• A natural blackjack (Ace + 10-value card) pays 3:2 in most casinos

A hard hand is any hand without an Ace, or with an Ace that counts as 1 to avoid busting (Ace + 6 + 9 = 16 hard). A soft hand contains an Ace counted as 11 without busting (Ace + 6 = 17 soft).

Why this matters: Soft hands give you flexibility because you can hit without the risk of busting. This changes optimal strategy:

• Soft 18 vs dealer 9,10,Ace: Hit (you can't bust)
• Hard 18 vs dealer 9,10,Ace: Stand (hitting risks busting)
• Soft 17 vs dealer 2-6: Double down (advantageous)
• Hard 17: Always stand

Dealer rules are fixed and vary by casino. The most common rules:

Standard rule: Dealer must hit on 16 and stand on 17. This is the most common rule in US casinos.

Variations:

• Dealer stands on soft 17 (S17): More favorable to players. Reduces house edge by about 0.2%
• Dealer hits on soft 17 (H17): Less favorable. Increases house edge by about 0.2%
• Dealer stands on all 17s (including soft): Most favorable variation

The best blackjack strategy is basic strategy — a mathematically optimal set of decisions that minimizes the house edge to as low as 0.5% when playing perfect basic strategy. Basic strategy tells you exactly when to hit, stand, double down, split, or surrender based on your hand and the dealer's upcard.

Key basic strategy rules:

• Always split Aces and 8s; never split 5s or 10s
• Double down on 11 against dealer 2-10 (except 11 against Ace)
• Stand on 17 or higher
• Hit on 12-16 if dealer has 7 or higher
• Surrender if available for 16 against dealer 9,10,Ace and 15 against dealer 10

The house edge in blackjack varies depending on the rules and how well you play. With perfect basic strategy, the house edge can be as low as 0.5% in games with favorable rules. However, most casino blackjack games have a house edge between 0.5% and 2%.

House edge by rule variations:

• 0.5% — 3:2 blackjack payout, dealer stands on soft 17, double after split allowed, surrender available
• 1.5% — 6:5 blackjack payout, dealer hits on soft 17, limited doubling
• 2%+ — Continuous shuffling machines, poor rules, not playing basic strategy

⚠️ Important: Always avoid 6:5 blackjack tables — they increase the house edge by 1.4% compared to 3:2 tables.

Almost never. Insurance is a side bet that pays 2:1 if the dealer has blackjack. The odds are heavily in the casino's favor unless you're counting cards and know that more than one-third of remaining cards are 10-value cards.

The math:

• Insurance costs half your original bet
• It pays 2:1 if dealer has blackjack
• Without card counting, the house edge on insurance is ~7.5%
• Card counters take insurance only when the true count is +3 or higher

Surrender is an option that allows you to forfeit your hand and recover half your bet. It's offered in some blackjack games and is highly valuable for reducing the house edge.

Two types:

• Early surrender: Surrender before the dealer checks for blackjack. Very rare and player-friendly (reduces house edge by 0.6-0.8%)
• Late surrender: Surrender after the dealer checks for blackjack. More common (reduces house edge by 0.1-0.2%)

When to surrender (late surrender):

• Surrender 16 against dealer 9, 10, Ace
• Surrender 15 against dealer 10
• Surrender 15 against dealer Ace (in some games)

Card counting is a strategy used to track the ratio of high cards (10s, face cards, Aces) to low cards (2-6) remaining in the deck. When more high cards remain, the player has a mathematical advantage.

The Hi-Lo counting system:

• Cards 2-6: +1
• Cards 7-9: 0
• Cards 10, J, Q, K, A: -1

You maintain a running count, then divide by remaining decks to get the "true count." When the true count is positive, you increase your bet size. When negative, you bet minimum or sit out.

• Back you off (ask you to stop playing)
• Share your information with other casinos

Online blackjack (RNG) uses a random number generator to determine card outcomes. Games are faster (50-100 hands/hour), have lower minimum bets ($1-5), and offer more rule variations. The house edge is typically 0.5-1%.

Live dealer blackjack uses real cards dealt by a human dealer streamed to your device. Games are slower (30-50 hands/hour), have higher minimum bets ($5-25), and offer a more authentic casino experience.

Many blackjack myths persist despite being mathematically incorrect. Here are the most common:

Myth 1: "The goal is to get as close to 21 as possible"

Myth 2: "Always assume the dealer has a 10 in the hole"
False. This is a beginner's heuristic that leads to poor decisions.

Myth 3: "Card counting is illegal"
False. Card counting is legal in all US jurisdictions.

Myth 4: "Hot and cold streaks exist"
False. Blackjack is a game of independent events. Past results don't affect future outcomes.
