NADO Blackjack

🎮 All apps

Blackjack with literally no dealer to trust: the house plays a fixed on-chain strategy (stands on 17), and its cards are drawn from future L1 block hashes bound after you stand — nothing to peek at, nothing to rig. Hit or stand as usual; win pays 2×, blackjack pays 5:2. Every card is verifiable on-chain. Post-quantum wallet, no install.

Provably fair — the dealer is an algorithm

Your cards bind to two future L1 block hashes the moment you bet or hit — card = HASH(blockhash(H) ‖ blockhash(H+1) ‖ hand ‖ n) mod 52 — and the dealer's hole card and hits are drawn the same way from blocks bound only after you stand. Nobody can peek, stack the deck, or grind the result (two blocks are mixed). The dealer must stand on 17 — a fixed strategy enforced by the contract, which also stores every card on-chain and pays wins (2×), pushes (refund) and naturals (5:2) automatically. Cards draw from an infinite shoe (each card independent), the one provably fair way to deal without a dealer.
