How to Verify BC.Game Bingo Results
Step 1: Get your seed data from BC.Game
To verify a Bingo bet, you need three pieces of data from BC.Game:
- Server Seed (Unhashed): Go to your account's Fairness settings. Click to reveal or unhash your server seed.
- Client Seed: Found in the same Fairness settings. You can use BC.Game's default or set your own custom seed.
- Nonce: Each bet has a unique nonce number. Find it in your bet history details.
Note: You can only verify bets made before you revealed/unhashed the server seed.
Step 2: Enter your data in the form above
Fill in the verification form with your bet data:
- Enter your Client Seed exactly as shown on BC.Game
- Enter the Server Seed (Unhashed) - this is the revealed seed, not the hashed version
- Enter the Nonce for the specific bet you want to verify
- Select the Number of Balls that were drawn in your game (typically 20)
The verifier calculates results using BC.Game's exact HMAC-SHA256 algorithm with sliding window selection.
Step 3: Compare the result with your bet
After clicking Verify, you'll see the sequence of drawn bingo balls:
- The results show balls numbered 1-51 in the order they were drawn
- Compare this sequence with the bingo balls shown in your BC.Game bet history
- Both the numbers and their order should match exactly
If results don't match, verify you're using the unhashed server seed, correct nonce, and the right number of balls.
Frequently Asked Questions
How many balls are used in BC.Game Bingo?
BC.Game Bingo uses a pool of 51 balls numbered 1-51. Typically, 20 balls are drawn per game, but this can vary from 10 to 30 balls depending on the game configuration. Each ball can only be drawn once per game.
What algorithm does BC.Game Bingo use?
BC.Game Bingo uses HMAC-SHA256 with a sliding window algorithm. For each ball draw, it generates a hash from the server seed, client seed, nonce, and draw index. The sliding window extracts bytes from the hash to select a ball from the remaining pool, then removes it before the next draw.
Why doesn't my verification result match?
Common reasons for mismatched results:
- Using hashed server seed: You need the unhashed (revealed) server seed from Fairness settings.
- Wrong ball count: Make sure you selected the correct number of balls that were drawn in your game.
- Wrong nonce: Each bet has a unique nonce - verify you're using the exact nonce for that specific bet.
- Seed pair mismatch: The seeds must match the pair that was active when the bet was placed.
Is my bet data safe when using this tool?
Absolutely. All verification happens 100% client-side in your browser using JavaScript. Your seeds, nonces, and bet data never leave your device - we don't collect, store, or transmit any information to our servers.
