How to play

Get closer to 21 than the dealer without going over.

• Tap chips to set your bet, then Deal.
• Hit takes another card. Stand keeps your hand.
• Double doubles your bet for exactly one more card.
• Split turns a pair into two hands, each with its own bet.
• Number cards count their number, J Q K count 10, A counts 1 or 11.

Payouts

Blackjack (A + 10-card)	3 to 2
Win	1 to 1
Tie with the dealer	Bet back

Table rules

• Dealer stands on all 17s, including soft 17.
• Dealer checks for blackjack when showing an A or a 10. If the dealer has it, you lose only your first bet.
• Double on any first two cards, also after a split.
• Split once. Split aces get one card each; A + 10 after a split counts as 21, not blackjack.
• Every card comes from a fresh 52-card deck, so earlier cards don't change the next one.
• No insurance, no surrender.

Fair play

Every card is fixed by the server seed, your seed and the hand number before you bet. The server seed stays secret until you change it; its fingerprint is shown now so it can't be swapped later.

How a card is made

Card n = 4 bytes of HMAC-SHA256(server seed, "your seed:hand number:⌊n÷8⌋") at position (n mod 8)×4, read as a number u, then ⌊u × 52 ÷ 2³²⌋. Cards are dealt in order: you, dealer, you, dealer, then every next card.
