How to Verify Stake Pump Results

Step 1: Get Your Seeds from Stake

After completing a Pump game on Stake.com or Stake.us, access your bet details. Click on the "Fairness" or "Provably Fair" option to reveal your client seed, the unhashed server seed, and the nonce used for that specific bet.

Step 2: Enter Seeds and Select Difficulty

Copy your client seed, server seed (unhashed), and nonce into the form above. Select the difficulty level you played (Easy, Medium, Hard, or Expert) to match the number of pop positions generated.

Step 3: Compare Pop Positions

The verifier will display all pop positions (balloon tiles that will burst) using the Fisher-Yates shuffle algorithm. Compare these results with your actual game outcome to confirm fairness.

Frequently Asked Questions

How does Stake Pump determine pop positions?

Stake Pump uses the Fisher-Yates shuffle algorithm seeded by HMAC-SHA256. The algorithm shuffles positions 0-24, converts them to 1-25, and based on difficulty (Easy=1, Medium=3, Hard=5, Expert=10), selects the first N positions as pop tiles.

What do the difficulty levels mean in Pump?

Each difficulty level determines how many balloon (pop) tiles are placed on the 25-tile grid: Easy has 1 pop, Medium has 3 pops, Hard has 5 pops, and Expert has 10 pops. Higher difficulty means more risk but also higher potential multipliers per safe balloon inflated.

What is the RTP of Stake Pump?

Stake Pump has a 98% RTP (Return to Player), meaning a 2% house edge. The payout multipliers are calculated based on the true mathematical odds of avoiding pop tiles at each step.

Does this verifier work for both Stake.com and Stake.us?

Yes, both Stake.com (crypto casino) and Stake.us (sweepstakes casino) use identical provably fair algorithms for the Pump game. This verifier works with seeds from either platform since the underlying HMAC-SHA256 Fisher-Yates implementation is the same.

Where do I find the unhashed server seed?

The unhashed server seed is revealed only after you rotate your seed pair on Stake. Go to Settings > Fairness, click "Rotate" or create a new seed pair, and the previous server seed will be unhashed. You can then verify all bets made with that seed pair.

Is my seed data safe with this verifier?

Absolutely. This verifier runs entirely in your browser using JavaScript. Your seeds are never transmitted to any server. All cryptographic calculations happen locally on your device, ensuring complete privacy.
