About This Game

Classic Blackjack, Verifiable Results


Fair21 is a pixel-art Blackjack card game built around player-verifiable fairness. Get closer to 21 than the dealer without going bust. Choose Hit, Stand, Double Down, Split, Insurance, or Surrender; a natural Blackjack pays 3:2.

Three Ways to Play


Play continuous hands at the Solo Table, join a three-seat Multiplayer Quick Table, or enter a seven-hand Elimination match. Elimination begins with 1,000 chips, removes the lowest stack after hand four, and crowns the final chip leader.

Choose the Seed. Audit the Hand.


Enter a player seed before each wager. A cryptographic commitment is locked before the cards are dealt; after settlement, the cards, actions, and result are revealed. Use the independent verifier to replay and audit the hand, then export the complete record.



Choose table themes, card backs, avatars, and music to build your pixel card room.
