Verify your HypeDrop roll
Recompute any past HypeDrop result on your own device using HypeDrop's published algorithm. Nothing you paste leaves your browser.
Step 1Where did you play?
Using HypeDrop / CSGORoll unboxing engine: HMAC-SHA256 (combined seed as key, empty message) over key = GAME-serverSeed-clientSeed-noncedetails
The combined string GAME-serverSeed-clientSeed-nonce (hyphen separators, game prefix such as BOXES or PVP_BOX) is used as the HMAC-SHA256 key over an empty message. The first 13 hex characters of the digest divide by 2^52 and multiply by the outcome count (floored). HypeDrop and CSGORoll publish byte-identical code for this engine.
Where to find your numbers on HypeDrop:
- Your client seed is visible and editable before unboxing.
- The server seed hash is shown before the unbox; the unhashed seed after.
- For battles, seeds and nonces are in the Provably Fair modal on the Battle Duel page.

What we can check on HypeDrop
Per-game status. "Verified" means our implementation reproduced a real, documented result for that game. We never list a game on trust.
| Game | Algorithm | Status |
|---|---|---|
| Unboxing | HMAC-SHA256 (combined seed as key, empty message) | Verified HypeDrop's verbatim unboxing code (extracted from their fairness page 2026-07-22) run independently in Node reproduces roll 19,569,993 for their own example seeds; our adapter matches. |
| Battle (PVP_BOX) | HMAC-SHA256 (combined seed as key, empty message) | Verified Reproduces HypeDrop's published vector (roll 35,864,249). |
| Upgrade | HMAC-SHA512 | Verified Reproduces HypeDrop's published vector (88.02). |
| Deal | HMAC-SHA256 (combined seed as key, empty message) | Awaiting confirmation |

The honest fine print
A passing check proves a specific outcome came from numbers fixed before you played. It does not prove HypeDrop 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.
