How to Verify Shuffle Limbo Results
Step 1: Get your seed data from Shuffle
To verify a Limbo bet on Shuffle, you need three pieces of data:
- Server Seed (Unhashed): Play a Limbo game on Shuffle. After the round ends, go to your bet history and click on the bet you want to verify. Look for the "Provably Fair" section to find the revealed server seed.
- Client Seed: Found in the same bet details section. You can use Shuffle's default or set your own custom seed.
- Nonce: Each bet has a unique nonce. Find it in your bet details for the specific round.
Note: The server seed is only revealed after you rotate to a new seed pair or after the bet is complete.
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, not the hash
- Enter the Nonce for the specific bet you want to verify
The verifier calculates the multiplier using Shuffle's exact HMAC-SHA256 algorithm with the formula: 16,777,216 / (result + 1) × 0.99
Step 3: Compare the result with your bet
After verification, you'll see the calculated Limbo result:
- The verifier displays the exact multiplier generated for that bet
- Compare this with your actual bet outcome in your Shuffle history
- If your target was below the multiplier, you won; if above, you lost
- The numbers should match exactly, confirming the game's fairness
If results don't match, double-check you're using the unhashed server seed and correct nonce.
Frequently Asked Questions
How does Shuffle Limbo work and what makes it different from Crash?
Limbo is an instant single-player game where you set a target multiplier and bet whether the result will be above or below it. Unlike Crash (which is multiplayer and takes time), Limbo results are instant. The game has a 99% RTP (1% house edge) with multipliers ranging from 1.00x to 1,000,000x. Higher target multipliers have lower probabilities but bigger payouts when you win.
Does this verifier work for both Shuffle.com and Shuffle.us?
Yes! Both Shuffle.com (international) and Shuffle.us (US version) use identical provably fair algorithms for Limbo. This verifier works for both platforms - just enter your seeds and nonce from either site. The HMAC-SHA256 verification process is the same across both versions.
How is the Limbo multiplier calculated on Shuffle?
The HMAC-SHA256 algorithm generates a hash from your seeds and nonce. The first 3 bytes (24 bits) are converted to an integer between 0 and 16,777,215. This number is then plugged into the formula: 16,777,216 / (n + 1) × 0.99 to produce the final multiplier. The 0.99 factor represents the 1% house edge, giving the game a 99% RTP.
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. This is only available after the bet is complete.
- Wrong nonce: Each bet has a unique nonce - verify you're using the exact nonce for that specific bet from your bet history.
- Seed pair mismatch: The seeds must be the pair that was active when the bet was placed. Check your bet details carefully.
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 once the page is loaded.
