Blackjack rules

Goal: get as close to 21 as possible without going over, and beat the dealer’s final total.

Hand values

• 2–10 are worth their face value.
• J/Q/K are worth 10.
• Ace is worth 1 or 11 (whichever is best for the hand).

What you can do

• Hit: take another card.
• Stand: stop taking cards.
• Double down: double your bet and take exactly one more card.
• Split: if your first two cards match, split into two hands (each with its own bet).

Dealer

• Dealer hits until at least 17.
• If you bust (over 21), you lose that hand automatically.
