Step 1Where did you play?

Using JemLit roll: HMAC-SHA512/256 over clientSeed-noncedetails

HMAC-SHA512/256 keyed with the server seed over clientSeed-nonce (hyphen separator). The entire 64-character digest is converted to an integer, divided by 16^64 and multiplied by 100, giving a roll between 0 and 100. Each item publishes a win range; the roll wins the item whose range contains it. Nonce starts at 1.

Where to find your numbers on JemLit:

Open the Fairness popup at the top of the page (top-left menu on mobile) to find your Server Seed, Client Seed and Nonce.
The server seed is shown hashed (SHA-512) before play and revealed after rotation.
Nonce starts at 1 and increases by 1 per bet.

Step 2Paste your numbers

Server seedThe site's secret number, revealed after your roll (or when you rotate seeds).

Client seedYour number. Find it in the site's fairness settings.

NonceThe roll counter. Copy it from the same screen as your seeds.

What we can check on JemLit

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-SHA512/256	Verified Reproduces JemLit's published documentation vector (roll 22.0231).

The honest fine print

A passing check proves a specific outcome came from numbers fixed before you played. It does not prove JemLit 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.
