Roat Pkz - Provably‑Fair Boxing Verifier

Fight History

Each tile shows HIT # (small) and the simultaneous damage dealt that turn (large).

The verifier simulates rounds of boxing with both players hitting each other simultaneously each turn until one or both reach 0 HP, exactly matching the server’s provably-fair logic.

How the hits work: A combined seed is created by concatenating player1_seed, player2_seed, and server_seed. Each successive counter value (:0, :1, :2 …) is hashed with SHA-256. The first 64 bits of each hash are mapped to a hit damage (0–16). Hits alternate between players, starting with Player 1. Anyone with the three seeds can reproduce every hit offline and prove the game server never altered the outcomes.
