How BC.Game Mines Works
Grid Layout
Mines uses a 5x5 grid (25 positions numbered 1-25). Mine positions are determined using a special shuffling algorithm with HMAC-SHA256 and SHA256.
Verification Algorithm
- Generate HMAC-SHA256(serverSeed, clientSeed:nonce)
- Start with BC.Game's predefined array: [7, 2, 19, 25, 1, 13, 5, 24, 14, 6, 15, 9, 22, 16, 3, 17, 18, 20, 8, 21, 4, 12, 10, 23, 11]
- First shuffle: Take SHA256 of the hash, assign rotated hash values to each position, then sort by hash
- Second shuffle: Take SHA256 again, shuffle the results from step 3
- The first N positions in the final shuffled array are the mine locations
