How to Verify Stake Drill Results
Step 1: Get your seed data from Stake
To verify a Drill 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 multipliers using Stake's exact HMAC-SHA256 algorithm.
Step 3: Compare the results with your bet
After clicking Verify, you'll see the calculated Drill results:
- The verifier displays the three multipliers generated for that bet, one per drill
- Compare these with your actual bet outcomes in your Stake history
- Each of the three drills has its own multiplier; your bet is settled on the drill you picked
- The numbers should match exactly
If results don't match, double-check you're using the unhashed server seed and correct nonce.
Frequently Asked Questions
How does Stake Drill work?
Stake Drill is a mining-themed game where you set a target multiplier and pick one of three drills. Each drill gets its own randomly generated multiplier, from 1.00x up to a maximum of 2,000,000x, and you win if your drill's multiplier meets or exceeds your target. The game uses a 2% house edge (98% RTP). Higher targets pay more but are hit less often.
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 Drill. This verifier works for both platforms - just enter your seeds and nonce from either site.
How is the Drill multiplier calculated?
The HMAC-SHA256 algorithm generates random bytes from your seeds and nonce. Each 4 bytes are converted to a float value between 0 and 1. The multiplier formula is: u < 0.02 ? 1 : min(0.98 / (1 - u), 2,000,000). This means values below 0.02 result in a 1x multiplier, while higher values produce multipliers up to 2,000,000x.
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.
- Seed pair mismatch: The seeds must be the pair that was active when the bet was placed.
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 is the difference between Drill and Limbo?
While both games produce multiplier outcomes, they have key differences. Limbo generates a single multiplier per bet with 99% RTP and uses a different formula. Drill generates three multipliers per bet, one for each drill, with 98% RTP: you pick a drill and a target before the round, and you win if your drill's multiplier meets or exceeds the target. Drill's multipliers are capped at 2,000,000x. In Limbo, 1,000,000x is the highest target and so the highest payout, while the result itself can reach 16,609,443.84x.
