Rollbit Originals verifier
Paste a revealed Rollbit secret seed and optional user seed. This page recomputes Plinko with Rollbit’s published BLAKE2b Python — not Stake, Shuffle or HMAC-SHA256 mappings. It is not on the unified /verify page yet. After the page loads, nothing is sent to a server.
What this page implements
BLAKE2b, not HMAC-SHA256
Rollbit’s published Plinko Python keys BLAKE2b-256 over secret + b"plinko-{ball}-{row}" + user_seed. The first eight digest bytes are a little-endian integer divided by 2⁶⁴ − 1. A float above 0.5 is a right bounce.
Per-round secret
The published construction uses a fresh 32-byte secret per round and an optional user seed. There is no Stake-style nonce cursor. The commitment shown before the round is BLAKE2b-256 of the secret alone.
Not on this page yet
Mines, X-Crash, X-Flip, X-Roulette, Rollbot Bonanza and Rollercoaster stay off this page until their live fairness snippets are confirmed. Rollbit also announced a VRF system in April 2024 for some of those titles — we will not guess that mapping.
Not the unified calculator
Stake, Shuffle, BC.Game and the other live tabs stay on /verify. This URL is Rollbit-only so you can check the numbers against rollbit.com before any tab is added there.
Does any of my data leave this page?
No. After the page loads, BLAKE2b runs in this browser tab. Seeds are not posted anywhere.
My live Plinko path does not match. What now?
First check you pasted the revealed secret (hex), not the commitment hash, and that the user seed is exactly as shown — including blank. If a live fairness panel still disagrees, it may be the 2024 VRF construction. Copy that snippet and we will switch the engine before this casino is added to /verify.
Why is only the 12-4 payout table included?
That is the table in the published config snippet. Other row and risk boards are not reproduced here, so this page reports the bounce path — the published random outcome — rather than inventing multipliers.
Where are Mines and X-Crash?
Their current fairness pages are behind a bot challenge from this machine, and we will not invent HMAC mappings for them. Once a live snippet is confirmed, those originals drop into this same picker.
