Shuffle.com Crash Verifier

Verify the crash multiplier in your Shuffle.com Crash game using cryptographic proof

Bet Information

How It Works

Shuffle.com Crash uses cryptographic hashing to generate crash points:

  1. Generate HMAC-SHA256 hash: HMAC(serverSeed, clientSeed:nonce:cursor)
  2. Convert the first 4 bytes of hash to a 32-bit integer
  3. Divide the integer by 2³² to get a float between 0 and 1
  4. Apply the crash formula: crashPoint = (99 / (1 - floatValue)) / 100
  5. The result is the multiplier at which the game crashes
  6. This incorporates a 1% house edge (99 in numerator)

Technical Note: The algorithm ensures fairness as neither player nor casino can predict or manipulate the outcome before the round begins.

About Shuffle Crash

  • House Edge: ~1%
  • Min Crash: 1.00x
  • Max Crash: Theoretically unlimited (extremely rare high values)
  • Algorithm: HMAC-SHA256 with float conversion
  • Verification: 100% client-side (your data stays private)
  • Result Precision: 2 decimal places (e.g., 2.45x)

Where to Find Seeds

  1. Play a Crash game on Shuffle.com
  2. Navigate to your bet history
  3. Click on the specific bet you want to verify
  4. Look for the "Provably Fair" or "Fairness" section
  5. Copy the Server Seed (unhashed), Client Seed, and Nonce
  6. Paste the values into the form above

Important: The unhashed server seed is only revealed after you rotate to a new seed pair. Active rounds cannot be verified until the seed pair is changed.
