Bet Information

How It Works

Shuffle.com Mines uses HMAC-SHA256 to place mines fairly:

  1. The game generates hashes using HMAC(serverSeed, clientSeed:nonce:cursor)
  2. Each hash produces up to 8 float values from the hex output
  3. Floats randomly select positions from remaining available tiles
  4. Process repeats with incrementing cursor until all mines are placed
