Blackjack Split Rules Explained

Splitting is allowed when your first two cards are of the same rank, such as two 8s or two Aces. You place an additional bet equal to your original wager and play each card as the start of a new hand. Each hand is then played independently.

Some games allow you to resplit if you draw another matching card, while others limit splitting to once per pair. Also, some tables restrict doubling after splitting, which affects your ability to capitalize on strong follow-up cards.

Aces and 8s are almost always recommended for splitting. Two Aces give you a chance to hit two natural blackjacks, though most games only allow one card after splitting Aces. Two 8s total 16, which is the worst possible hand, so splitting gives you a better shot at improvement.

On the other hand, never split 10s or 5s. A pair of 10s already totals 20, a very strong hand. A pair of 5s is better played as a 10, where you can double down and aim for 20 or 21.

• Always split Aces and 8s
• Never split 10s or 5s
• Split 2s, 3s, and 7s against dealer 2–7
• Split 6s against dealer 2–6
• Avoid splitting 4s unless dealer shows 5 or 6

Splitting wisely is a hallmark of skilled blackjack play. While it increases your risk by requiring an additional bet, it also opens opportunities to win more when conditions are favorable. Following basic strategy ensures you split only when the odds are in your favor.

Always check the specific rules of the game you're playing. Some tables pay 6:5 on blackjack after splitting, or limit resplits, which can affect your long-term returns. A solid understanding of split rules gives you a clear edge over casual players.
