Blackjack is the classic casino card game also known as 21. Your goal is to beat the dealer by getting a hand value as close to 21 as possible without going over (busting).
Always hit on 11 or less. Stand on 17 or higher. With 12-16, stand if the dealer shows 2-6, otherwise hit. Double down on 10 or 11 when you have more than the dealer's up card.
Fun Fact: Blackjack has the lowest house edge of any casino game when played with perfect strategy - just about 0.5%! Card counting can even give skilled players an edge.
