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): Shuffle reveals it when you rotate your seed pair. Open the Limbo bet in your bet history, rotate the pair from its Provably Fair section, and the bet's details then show the unhashed 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: Shuffle reveals a server seed only when you rotate the seed pair; finishing a round does not reveal it. Every bet made on the old pair can then be verified.

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: 0.99 × 16,777,216 / (16,777,216 × float + 1), rounded down to 2 decimals

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 win if the result is higher than your target; there is no under bet, and Shuffle's game shows a result exactly equal to your target as a draw, not a win. 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 4 bytes become a float between 0 and 1, which goes into the formula 0.99 × 16,777,216 / (16,777,216 × float + 1) to produce the multiplier. Shuffle shows it rounded down to 2 decimals. 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. Shuffle shows it once you rotate your seed pair.
  • 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.
