Beat the dealer's hand without going over 21. Face cards count 10, aces 1 or 11. Hit to take a card, stand to keep your hand, double to double your bet for exactly one more card, and split a pair into two hands (up to four). The dealer draws to 16 and stands on every 17, and a blackjack pays 3 to 2.

When the dealer shows an ace you're offered insurance (it pays 2 to 1 if the dealer has blackjack), or even money when you hold a blackjack yourself. Two side bets ride on the deal: Perfect Pairs on your first two cards, and 21+3 on them with the dealer's up card. Tap a side bet on the table to put your bet amount on it (tap again to add more); a right-click or a long press takes it off.

The eight-deck shoe is shuffled from your own provably fair seed pair when your bet goes in, before the first card. Check any hand on the Provably fair page. A hand left alone stands after ten minutes.
