Crash 1v1

About

Crash 1v1 is a head-to-head duel on the same Crash curve. Both players bet equal stakes; the multiplier rises until it busts. The player who cashed out at the higher multiplier wins the combined pot minus a small rake. If both bust, both lose.

How a round plays

• Open a lobby and match with another player at the same stake.
• The round runs the same curve for both. The bust point is fixed before the round starts.
• Whoever cashes out at the higher multiplier wins the pot, minus a 1% rake.
• If both bust, both stakes are lost.

Provably fair

• The bust point is derived from HMAC-SHA256(server_seed, client_seed || nonce), shared by both players in the duel.
• Server seed is committed before the round, revealed after rotation.
• After rotation, the verifier reproduces the bust point from the shared seed pair + nonce.

Every round is verifiable from a server seed (revealed after rotation), your client seed, and a per-round nonce. See how it works for the full construction.
