Solcasino Originals verifier
Paste a revealed Solcasino server seed, client seed and nonce. This page recomputes first-party Originals (/game/dice and the rest) and UN-Originals with Tequity’s HMAC-SHA256 + uint32 reject construction. It is not on the unified /verify page yet. After the page loads, nothing is sent to a server.
What this page implements
Two catalogs, one seed pair
Solcasino’s Originals filter is 12 first-party titles at /game/dice, /game/mines and so on. The same hub also lists UN-Originals, whose producer is Tequity. Solcasino’s fairness docs describe one client seed / hashed server seed / nonce rotation for originals.
HMAC + uint32 stream
This calculator keys HMAC-SHA256 with the revealed server seed and signs clientSeed:nonce:cursor. Each digest is eight big-endian uint32 words. A draw of 0…limit−1 keeps the low ceil(log2(limit)) bits and rejects the word when that value is ≥ limit. That is Tequity’s proveFairness map — not Stake’s 4-byte float.
Not on this page
Coin Flip, Tower and Lottery stay off until their extra tables can be labelled without guessing. Slider, Cross the Road and Dragon’s Tower on UN-Originals stay off for the same reason.
Not the unified calculator
Stake, Shuffle and BC.Game stay on /verify. This URL is Solcasino-only so you can check the numbers against solcasino.io before any tab is added there. It is not on the unified /verify page yet.
Does any of my data leave this page?
No. After the page loads, hashing runs through the browser Web Crypto API. Seeds are not posted anywhere — including not to Solcasino or Tequity.
Where do I copy the seeds?
Open a Solcasino Original, then Fairness. Client seed and nonce are on the seed pair. Rotate the pair to reveal the old server seed, then paste that revealed value here. The hashed server seed is optional and only used to confirm the SHA-256 commitment.
Why are UN-Originals on this page?
They sit on the same /games/originals hub. Their producer is Tequity, so the HMAC construction is the one this calculator implements. Use /game/un-originals-dice (and the rest) when you want that catalog.
My result doesn’t match Solcasino. What went wrong?
Check you pasted the revealed server seed, not the hash; that the nonce belongs to that bet; and that you picked the same title (first-party Dice vs UN-Originals Dice). A genuine first-party mismatch is worth reporting — and is exactly why this page is still off the unified /verify hub.
