Mines
Provably fair mines verifier
Paste the revealed server seed, your client seed, the nonce, and the mine count from that round. The 5x5 layout is rebuilt with the same Fisher-Yates stream used by the game server.
Mine tiles (0-24, row-major)
SHA-256(server seed)
Algorithm: fill tiles 0..24, then Fisher-Yates shuffle using
SHA-256(client_seed:server_seed:nonce:blockIndex) as a 4-byte stream
with rejection sampling. The first mineCount tiles after the shuffle are mines.
Query params: client_seed, server_seed, nonce, mines, hash.
