How to Verify BC.Game Crash Results
Step 1: Get your seed data from BC.Game
To verify a Crash bet, you need three pieces of data:
- Server Seed (Unhashed): Go to Fairness settings on BC.Game. Click "Unhash" next to your active server seed to reveal it.
- Client Seed: Found in the same Fairness settings page. You can use BC.Game's default or set your own custom seed.
- Nonce: Each bet has a unique nonce. Find it in your bet history by clicking on the bet details.
Note: You can only verify bets made before you unhash the server seed.
Step 2: Enter your data in the form above
Paste your data into the verification form:
- Enter your Client Seed exactly as shown on BC.Game
- Enter the Server Seed (Unhashed) - this is the revealed seed, not the hash
- Enter the Nonce for the specific bet you want to verify
The verifier calculates the crash multiplier using BC.Game's exact HMAC-SHA256 algorithm.
Step 3: Compare the result with your bet
After clicking Verify, you'll see the calculated crash multiplier:
- The result will be the crash multiplier (e.g., 1.98x, 5.42x, etc.)
- Compare this with the crash point shown in your BC.Game bet history
- If they match exactly, the bet was provably fair
If results don't match, double-check you're using the unhashed server seed and correct nonce.
Frequently Asked Questions
What is BC.Game Crash and how does it work?
BC.Game Crash is a multiplier game where a line rises from 1.00x upward. The game randomly crashes at a multiplier between 1.00x and potentially thousands of x. Players must cash out before the crash to win their bet multiplied by the current value. The crash point is determined using provably fair cryptographic algorithms with a 99% RTP (1% house edge).
How does BC.Game calculate the crash multiplier?
BC.Game uses HMAC-SHA256 to generate a random float value between 0 and 1 from your server seed, client seed, and nonce. The crash multiplier is then calculated using the formula: 99 / (1 - floatValue). This ensures every result is cryptographically verifiable and provably fair.
Why doesn't my verification result match?
Common reasons for mismatched results:
- Using hashed server seed: You need the unhashed (revealed) server seed, not the hashed version.
- 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 be the exact 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. You can even use this tool offline.
