Every mines game is mathematically verifiable. The server cannot change the mine positions after your bet — proven by SHA-256.
Before the game starts, the server generates a serverSeed and sends you its SHA-256 hash. It cannot change the seed after this point.
You provide a clientSeed. The mine positions are derived from SHA-256(serverSeed:clientSeed:nonce:attempt), ensuring neither party can manipulate the result.
After the game, the serverSeed is revealed. You can verify the mine positions were fair by entering the seeds below.
