Gamdom Plinko verifier
Independently check any Gamdom Plinko bet. Plinko drops a ball through a triangle of pegs. Each row uses one float to decide left or right. Faircheck rebuilds the full path and the bin the ball settles in, for any row count from 8 to 16.
One of the older crypto casinos, with provably-fair originals verifiable from the revealed seed pair.

How to verify Gamdom Plinko
- Reveal the seed. Open Gamdom’s provably-fair panel and rotate your seed pair — this reveals the previous server seed and shows the SHA-256 hash it was committed to before you bet.
- Find the nonce. Each bet on a seed pair has an incrementing nonce. Use the nonce of the exact Plinko round you want to check.
- Paste & verify. Drop the server seed, client seed and nonce into the form above. Faircheck recomputes the landing bin and confirms the seed hash matches.
The Plinko formula
Bytes from HMAC-SHA256(serverSeed, `clientSeed:nonce:round`), converted to floats and mapped per game. The server seed is committed as a SHA-256 hash before the bet and revealed when you rotate seeds.
One float is drawn per row (8 to 16 floats total, depending on the risk level).
A float below 0.5 sends the ball left, otherwise right.
The landing bin is the number of right moves — that index selects the payout multiplier on the board.

How many rows should I pick?
It depends on the board you played — Stake’s rows range from 8 (low) to 16 (high). The path only matches if the row count matches your bet.
