How to Verify Stake Primedice Results
Step 1: Get your seed data from Stake
To verify a Primedice bet, you need three pieces of data:
- Server Seed (Unhashed): Go to Settings → Fairness on Stake. Click "Unhash" next to your active server seed to reveal it.
- Client Seed: Found in the same Fairness settings page. You can use Stake's default or set your own.
- Nonce: Each bet has a unique nonce. Find it in your bet history by clicking on the bet.
Note: You can only verify bets made before you unhash the server seed.
Step 2: Enter your data in the form above
Paste your data into the verification form:
- Enter your Client Seed exactly as shown on Stake
- 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 result using Stake's exact HMAC-SHA256 algorithm.
Step 3: Compare the result with your bet
After clicking Verify, you'll see the calculated Primedice result:
- The result will be a number between 0.00 and 100.00
- Compare this with the dice roll shown in your Stake bet history
- If they match exactly, the bet was provably fair
If results don't match, double-check you're using the unhashed server seed and correct nonce.
Frequently Asked Questions
What is Primedice and how is it different from Stake Dice?
Primedice was the original provably fair dice game that Stake acquired. It generates results from 0.00 to 100.00, while Stake Dice uses a range of 0.00 to 99.99. Both games have 99% RTP and 1% house edge, but use slightly different calculation formulas.
Does this verifier work for both Stake.com and Stake.us?
Yes! Both Stake.com (international) and Stake.us (US sweepstakes) use identical provably fair algorithms for Primedice. This verifier works for both platforms - just enter your seeds and nonce from either site.
How is the Primedice roll calculated?
The calculation uses HMAC-SHA256 to generate a hash from your server seed, client seed, nonce, and cursor. The first bytes are converted to a float between 0 and 1, then the formula floor(float × 10001) / 100 produces a result from 0.00 to 100.00.
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.
- Wrong nonce: Each bet has a unique nonce - verify you're using the exact nonce for that bet.
- Wrong verifier: Make sure you're using Primedice (0.00-100.00) not regular Dice (0.00-99.99).
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.
What other dice games can I verify?
We offer a separate Stake Dice verifier for the 0.00-99.99 range game. Both games are provably fair but use slightly different formulas. View all our verification tools on the Stake verifiers page.
