How BC.Game Bingo Works
Verification Algorithm
- Start with a pool of 51 bingo balls (numbered 1-51)
- For each ball draw (index 0 to numBalls-1):
- Generate HMAC-SHA256(serverSeed:drawIndex, clientSeed:nonce)
- Use sliding window algorithm to extract ball index
- Extract first 15 hex chars, convert to decimal, modulo 47 for start position
- Extract 14 chars from start position, divide by 8, scale with 2^-53
- Multiply by remaining balls count to get selection index
- Remove selected ball from pool, repeat for next draw
Understanding the Results
- Drawn Balls: The sequence of balls drawn in order
- Ball Range: Numbers from 1 to 51
- Draw Order: Balls shown in the order they were drawn
- No Duplicates: Each ball can only be drawn once per game
