How to Verify Shuffle Mines Results
Step 1: Get your seed data from Shuffle
To verify a Mines bet on Shuffle.com or Shuffle.us, you need four pieces of data:
- Server Seed (Unhashed): After your game ends, go to your bet history and click on the bet. The unhashed server seed is revealed in the Provably Fair section.
- Client Seed: Found in the same bet details. You can use Shuffle's default or set your own custom seed.
- Nonce: Each bet has a unique nonce number. Find it in the bet details.
- Number of Mines: The number of mines (1-24) you selected for that game.
Note: The server seed is only revealed after the game ends or when you rotate to a new seed pair.
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
- Enter the Number of Mines (1-24) used in your game
The verifier calculates mine positions using Shuffle's exact HMAC-SHA256 with Fisher-Yates shuffle algorithm.
Step 3: Compare mine positions with your game
After clicking Verify, you'll see the calculated mine positions:
- The verifier displays the exact positions of all mines on the 5×5 grid
- Mine positions are shown as coordinates (row, column) and visual grid
- Compare these positions with your actual game board in Shuffle
- The positions should match exactly
If results don't match, double-check you're using the unhashed server seed, correct nonce, and exact mine count from your game.
Frequently Asked Questions
How does Shuffle Mines work?
Shuffle Mines is played on a 5×5 grid (25 tiles total) where you choose how many mines to place, ranging from 1 to 24. You click tiles one by one to reveal safe spots while avoiding mines. Each safe tile you uncover increases your multiplier, and you can cash out at any time. The more mines you add, the higher the potential multiplier but the greater the risk. The game uses HMAC-SHA256 with Fisher-Yates shuffle to ensure mine positions are provably fair and predetermined before you start playing.
Does this verifier work for both Shuffle.com and Shuffle.us?
Yes! Both Shuffle.com (crypto casino) and Shuffle.us (sweepstakes casino for US players) use identical provably fair algorithms for Mines. This verifier works for both platforms - just enter your seeds, nonce, and mine count from either site. The verification process and results will be the same regardless of which platform you're using.
How are mine positions calculated in Shuffle Mines?
Shuffle uses HMAC-SHA256 to generate cryptographically secure random values from your server seed, client seed, and nonce. The algorithm creates hashes with incrementing cursor values, converting hash bytes to floating-point numbers between 0 and 1. These floats are then used with the Fisher-Yates shuffle algorithm to randomly place mines on the 5×5 grid. Each cursor iteration produces up to 8 float values from the hash until all mines are placed in unique positions.
What information do I need to verify a Shuffle Mines game?
You need four pieces of information to verify a Mines game:
- Unhashed Server Seed: The revealed server seed (not the hashed version) from your bet details.
- Client Seed: Your unique client seed that was active during the bet.
- Nonce: The bet number in your seed pair sequence.
- Number of Mines: How many mines (1-24) were selected for that specific game.
All of this information is available in the Provably Fair section of your bet details after the game ends.
Is my data safe when using this Shuffle Mines verifier?
Absolutely. All verification happens 100% client-side in your browser using JavaScript. Your seeds, nonces, mine count, and bet data never leave your device - we don't collect, store, or transmit any information to our servers. The entire calculation runs locally on your computer, ensuring complete privacy and security of your sensitive data.
