Blackjack Rules for Beginners — Everything You Need to Know

Unlike players, the dealer has no choices to make — they must follow fixed rules: • The dealer must hit on any hand totalling 16 or less • The dealer must stand on any hand totalling 17 or more • In some variants, the dealer hits on 'soft 17' (Ace + 6) — this is noted as 'H17' and increases the house edge slightly • The dealer always acts last — if you bust, you lose before the dealer plays The dealer's forced rules are what give blackjack its strategic element. Because you know exactly what the dealer must do, you can make mathematically optimal decisions based on their visible card.

When your first two cards have the same value, you can split them into two separate hands: • Each split hand receives a new second card • You must place an additional bet equal to your original bet for the second hand • You can usually split up to 3 times (creating 4 hands total) • Aces are typically split only once, and you receive only one card per Ace • Some casinos allow 'resplitting' Aces — check the variant rules When to split: Always split Aces and 8s. Never split 10s or 5s. The correct splitting decision for other pairs depends on the dealer's upcard — consult a basic strategy chart.

Doubling down allows you to double your bet in exchange for receiving exactly one more card: • You can double down on any two-card hand in most variants • Some variants restrict doubling to hands totalling 9, 10, or 11 only • After doubling, you receive one card and must stand — no further hits • You can usually double after splitting When to double: The most profitable doubling situations are when you hold 10 or 11 and the dealer shows a weak card (2–9). Doubling on 9 is correct against dealer 3–6. Always consult a basic strategy chart for precise guidance.

Different blackjack variants have different rules that affect the house edge: Number of decks: Single-deck blackjack has the lowest house edge (around 0.15% with perfect strategy). More decks increase the house edge slightly. Dealer hits or stands on soft 17: Dealer hitting soft 17 (H17) increases the house edge by about 0.2%. Blackjack payout: Standard is 3:2. Some casinos pay 6:5 — this increases the house edge by 1.39% and should be avoided. Surrender: Early surrender (before dealer checks for blackjack) is rare but valuable. Late surrender (after checking) is more common and reduces the house edge by about 0.07%. Double after split: Allowed in most variants — reduces house edge by about 0.14%.
