Blackjack Rules

Single deck, server-authoritative, provably fair. Beat the dealer without going over 21. The full 52-card deck order is committed up front; the fairness page can replay the entire hand from the revealed seed.

The rules, exactly

  1. Single deck. No surrender, no splits.
  2. You get 2 cards face-up. The dealer gets 1 up and 1 hole card, revealed when you stand, double, bust, or on an immediate blackjack.
  3. Blackjack (an ace plus a 10-value card on your first two) pays 3:2, 2.5x your stake back in total.
  4. Hit: draw a card. Stand: the dealer plays. Double: double the stake, draw exactly one card, then stand. Double only on the first decision.
  5. The dealer hits on 16 and stands on all 17s, soft 17 included.
  6. You bust, you lose. Dealer busts, you win 1:1. Higher hand wins 1:1. Equal hands push and your stake returns. Both blackjack is a push.

All payouts are integer whole GP, rounded down. Card values are the standard ones: aces 1 or 11, face cards 10, everything else face value.

Know the rules. Trust the math.Every round is verifiable after the fact on /fair.
