About this site

Why this exists

Mystery box and case opening sites tell millions of players their results are "provably fair". Provably fair only means something if someone outside the operator actually does the proving. Independent verifiers have existed for years for crypto sites with games like dice and crash, but none covered the mystery box vertical. Players arguing about a roll in a Discord server had nowhere neutral to check it. This site is that place.

What we are

• A free verifier that recomputes box and case results from their seeds, entirely in your browser. Your numbers never reach our servers or anyone else's.
• A per-platform record of what each site actually publishes about its fairness system, and whether our implementation of it reproduces real results. The rules we follow are on the methodology page.

What we are not

• Not owned or sponsored by any mystery box or case opening operator we cover, with one disclosed exception: this site is operated by Punch Gaming Inc., which also operates Ripster.gg. We hold Ripster.gg to the exact same published verification standard as every other platform, and say so plainly rather than hide it. Full detail in the Terms of Use.
• Not a recommendation engine. A platform being verifiable is a fact about its math, not an endorsement of its business.
• Not a predictor. Nothing can predict a future roll, and anyone selling prediction is running a scam.

Independence and money

The verifier is free and carries no ads inside the tool. If this site ever earns money, it will be through clearly marked affiliate links on editorial pages, and never in exchange for a verification status. The full policy is in the affiliate disclosure.
