Beat the dealer to 21 - blackjack pays 3:2, dealer stands on soft 17
Blackjack is a race to 21 against the dealer. Number cards count face value, jacks, queens, and kings count 10, and aces count 1 or 11 - whichever helps you more. Place a bet with the chip buttons, hit Deal, and you receive two cards face up while the dealer gets one up and one face down. From there you can Hit for another card, Stand to keep your total, Double to double your bet in exchange for exactly one more card, or Split a matching pair into two separate hands. Go over 21 and you bust immediately; otherwise the dealer reveals the hole card and must draw to 17, standing on all 17s including soft 17. An ace plus a ten-value card on the deal is a blackjack and pays 3:2. This table uses a six-deck shoe and offers no insurance bet - which is no loss, since insurance is a losing wager anyway.
You start with 1,000 chips, and your best chip stack is what lands on the leaderboard. If you go broke, a rebuy resets you to 1,000 - but your recorded high score is always the biggest stack you've ever built.
