A provably-fair, staked 2-player coin flip on the NADO execution layer. Both stake NADO into a pot; the winner takes it all. Each player commits to a secret with their stake; once both are in, both secrets are revealed and the coin is the parity of HASH(secret1 + secret2 + game) — neither player can steer it. Your browser reveals for you. Post-quantum wallet, no install.
Signed by your NADO wallet — confirm each move there, then bounce back; your key never touches this site. Stakes live in the execution layer: deposit NADO to bet, withdraw winnings any time.

The coin is HASH(secret1 + secret2 + game) mod 2 — heads pays slot 1, tails pays slot 2.
• Commit. Your browser draws a random secret, saves it, and stakes with its hash HASH(secret). The hash reveals nothing about the secret, and it locks you to it.
• Reveal. Once both players are in, each browser reveals its secret automatically; the contract checks it against the commitment. Neither player knew the other's secret when committing, so neither can steer the sum — and no block producer is involved.
• Withholding never pays. Reveals must land within the reveal window after the join. If only one player reveals, that player takes the whole pot; if neither does, both stakes are refunded. Anyone can settle, and before an opponent joins the opener can cancel and reclaim. Escrow and payout reconcile exactly on-chain — nothing minted or lost.
• Games opened before this rule settle as they always did, from two finalized block hashes.
Same game, play chips: nothing touches the chain, no wallet needed. When you're ready for real NADO, use the tables above.
