Is RillaBox provably fair?
Box openings: a five-step narrative (SHA-256 commitment, 0-100 result at 4 decimals) but no formula, no combination string, no nonce, and no public seed access, so they cannot be independently verified as implemented. Re-read 2026-10-04: fairness is now split per game, the old /provable-fairness URL lands on the Crash page, and Crash alone publishes runnable Python (BLAKE2b hash chain with a Bitcoin-block global seed). Crash is not a box opening and is not covered here.
Where verification stands
A site is only provably fair if an outsider can recompute its results from published math. RillaBox currently doesn't publish what that would take, so its fairness claims can't be independently checked, by us or by anyone else.

Asking a different question?
This page is for checking a result you already have. If what you actually want to know is whether RillaBox is worth using at all, who runs it and what players report about getting paid, that is a separate piece: is RillaBox legit?
The honest fine print
A passing check proves a specific outcome came from numbers fixed before you played. It does not prove RillaBox will honour a withdrawal, or say anything about the site beyond this one result. Fair math and a trustworthy business are different things: how we verify and what it means.
