The classic game of 21, tuned for friendly play. Read the table, decide to hit, stand or double down, and try to outscore the dealer without busting. Virtual coins, real brain-teaser.
Closest to 21 without going over wins. Dealer stands on 17.
Place your bet and press Deal. You'll get two cards face up; the dealer shows one. Get closer to 21 than the dealer without busting — but the dealer has to draw to 16 and stand on 17, so let them bust when you can.
Hit draws another card. Stand ends your turn. Double doubles your bet for exactly one more card. A natural blackjack (Ace + 10-value) pays 3:2.
