How BC.Game Bingo Works

Verification Algorithm

  1. Start with a pool of 51 bingo balls (numbered 1-51)
  2. For each ball draw (index 0 to numBalls-1):
  3. Generate HMAC-SHA256(serverSeed:drawIndex, clientSeed:nonce)
  4. Use sliding window algorithm to extract ball index
  5. Extract first 15 hex chars, convert to decimal, modulo 47 for start position
  6. Extract 14 chars from start position, divide by 8, scale with 2^-53
  7. Multiply by remaining balls count to get selection index
  8. Remove selected ball from pool, repeat for next draw
