Shuffle Provably Fair
Game Verification

To verify any Shuffle original game, you need three pieces of data from your bet:

• Server Seed (Unhashed): Shuffle reveals it when you rotate your seed pair. Open a bet, rotate the pair from its Provably Fair section, and the bet's details then show the unhashed server seed.
• Client Seed: Shown in the same bet details. You can keep the one your browser generated or set your own.
• Nonce: Each bet has a unique nonce number. Find it in your bet history by clicking on any bet to see its details.

💡 Tip: Rotating reveals the server seed of the pair you are leaving, so every bet made on that pair can be verified. Crash is the exception: it uses each round's hash, not your seeds, so a Crash round can be checked as soon as it ends.

Follow these simple steps to verify any Shuffle original game:

• Step 1: Choose your game below — Dice, Crash, Mines, Limbo, or any other Shuffle original.
• Step 2: Enter your Server Seed (unhashed), Client Seed, and Nonce in the input fields (for Crash, the round's hash instead).
• Step 3: Click "Verify" — the tool instantly calculates the result using Shuffle's exact algorithm.
• Step 4: Compare the calculated result with your actual bet outcome. They should match exactly.

💡 Pro tip: Some games need the settings you played with: the mine count for Mines, rows and risk for Plinko, segments and risk for Wheel, and the difficulty for Waifu Tower.

Each verifier shows you exactly what the cryptographic calculation produced:

• Dice/Limbo: Shows the calculated roll (0.00-100.00) or multiplier — compare against your actual result.
• Crash: Displays the round's crash point (e.g., 2.47x), worked out from its hash step by step — it should match the crash point Shuffle shows for the round.
• Mines/Keno: Reveals exact tile/number positions — you can see where mines were placed or which Keno numbers were drawn.
• Cards (HiLo, Blackjack): Shows the round's 52-card stream in order, each card drawn from a full deck (nothing is shuffled), with Blackjack's opening deal marked.

💡 What if it doesn't match? Double-check you entered the correct seed pair and nonce. The server seed must be unhashed (revealed), not the hashed version.

These tools scan a range of nonces on a seed pair:

• Mines Pattern Finder: Enter your seeds and pick the tiles you want safe. The tool finds the nonces where every tile you picked is safe.
• Limbo Target Finder: Set a target multiplier (e.g., 10x or higher). The tool finds the nonces whose result meets or exceeds your target.

💡 Important: Both tools need the unhashed server seed, which Shuffle reveals only when you rotate the pair. So they analyze seed pairs you have already rotated away from, not your active one.
