How to Verify BC.Game HiLo Results
Step 1: Get your seed data from BC.Game
To verify a HiLo bet, you need the following data from BC.Game:
- Server Seed (Unhashed): Access your provably fair settings on BC.Game. Reveal the server seed to get the unhashed version.
- Client Seed: Found in the same provably fair settings. You can use BC.Game's default or customize your own.
- Nonce: Each bet has a unique nonce number. Find it in your bet details or history.
- Round Number: The card position in the game sequence (0 for the first card, 1 for second, etc.).
Note: You can only verify bets made before revealing the server seed.
Step 2: Enter your data in the form above
Input your verification data into the form:
- Paste your Client Seed exactly as shown on BC.Game
- Enter the Server Seed (Unhashed) - the revealed seed, not the hashed version
- Enter the Nonce for the specific bet you want to verify
- Enter the Round Number (0 for first card, 1 for second card, etc.)
The verifier uses BC.Game's exact HMAC-SHA256 algorithm to calculate the card.
Step 3: Compare the result with your bet
After clicking Verify, you'll see the calculated card result:
- The result will show a card from the 52-card deck (Ace through King with suit)
- Compare this with the card shown in your BC.Game bet history
- If they match exactly (both value and suit), the bet was provably fair
If results don't match, double-check you're using the unhashed server seed, correct nonce, and proper round number.
Frequently Asked Questions
How does BC.Game HiLo work?
BC.Game HiLo uses a standard 52-card deck. You're shown a card and must predict whether the next card will be higher or lower in value. The game uses provably fair cryptographic hashing to determine each card, ensuring fairness and transparency.
What is the round number in BC.Game HiLo?
The round number represents the card position in the game sequence. The first card is round 0, the second card is round 1, and so on. Each round uses the same nonce and seeds but with a different round number to generate unique card results.
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 correct nonce for that specific bet.
- Wrong round number: Make sure you're verifying the correct card in the sequence (0 for first card, 1 for second, etc.).
- Seed pair mismatch: The seeds must be 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.
Can I verify multiple cards from the same game?
Yes! To verify multiple cards from the same HiLo game, use the same client seed, server seed, and nonce, but change the round number. Use 0 for the first card, 1 for the second, 2 for the third, and so on. Each round number will generate a different card from the same game session.
