Every pull's outcome is locked in by cryptography before you open the pack — and you hold one of the keys. This page recomputes any pull, entirely in your browser. Nothing is sent to our servers. View source to confirm.
01 · BEFORE YOU PULL
We publish a fingerprint (SHA-256 hash) of our secret seed in your Fairness screen. It's locked — we can't change it after the fact.
02 · EVERY PULL
Your outcome = HMAC-SHA256 of our seed + your seed + the pull number. You're an ingredient in the roll — we can't pre-cook it.
03 · WHEN YOU CHECK
Rotate your seed in the app to reveal our secret. Paste it below — the math must reproduce your exact pulls, or we cheated.
Verify a pull
Find these values in the app: Fairness screen → your pulls → Verify.
What this proves: the outcome of every pull was mathematically fixed the moment you pulled — nobody at Pullz can see a roll and change it. Your seed is part of the mix, so we can't pre-select outcomes either. The odds table used for your pull is stored with it, so the tier mapping is checkable too. Standard HMAC-SHA256 — you can verify with any independent tool, not just this page.
Fairness you can check beats fairness you're promised.
