How to Verify Shuffle HiLo Results
Step 1: Get your seed data from Shuffle
To verify a HiLo bet, you need three pieces of data:
- Server Seed (Unhashed): After your round ends, check your bet details or provably fair section on Shuffle to find the revealed server seed.
- Client Seed: Found in your bet history or provably fair settings. You can customize this seed before playing.
- Nonce: Each bet has a unique nonce. Find it in your bet details - it represents the bet number in your current seed pair.
Note: The server seed is only revealed after the game round is completed.
Step 2: Enter your data in the form above
Paste your data into the verification form:
- Enter your Client Seed exactly as shown on Shuffle
- Enter the Server Seed (Unhashed) - this is the revealed seed from your completed bet
- Enter the Nonce for the specific bet you want to verify
The verifier calculates the card sequence using Shuffle's exact HMAC-SHA256 algorithm.
Step 3: Compare the results with your bet
After clicking Verify, you'll see the complete card sequence:
- The verifier will display all 52 cards in the exact order they were dealt
- Each card shows its rank (A, 2-10, J, Q, K) and suit (Hearts, Diamonds, Clubs, Spades)
- Compare the card sequence with your actual game results on Shuffle
- If they match exactly, the bet was provably fair
If results don't match, double-check you're using the correct server seed and nonce from that specific bet.
Frequently Asked Questions
How does Shuffle HiLo game work?
Shuffle HiLo uses a standard 52-card deck. You're shown a card and must predict whether the next card will be Higher or Lower. The game uses HMAC-SHA256 to generate a provably fair card sequence from your server seed, client seed, and nonce.
Does this verifier work for both Shuffle.com and Shuffle.us?
Yes! Both Shuffle.com (international) and Shuffle.us (US sweepstakes) use identical provably fair algorithms for HiLo. This verifier works for both platforms - just enter your seeds and nonce from either site.
Why doesn't my verification result match?
Common reasons for mismatched results:
- Using hashed server seed: You need the unhashed (revealed) server seed shown after the game ends, 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 your HiLo 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.
What are the card values in Shuffle HiLo?
