Recompute any Limbo round from the revealed server seed, your client seed and the nonce. House edge: ~1%.
One float is converted into a multiplier with the formula 0.99 / (1 − float). The result is capped below at 1.00x — you win when the drawn multiplier reaches your target.
The same draw drives every target, so a 2x target and a 100x target verified with the same seeds produce the same underlying multiplier.
Odds and payouts
P(win) ≈ 0.99 / target multiplier. A 2x target hits ~49.5% of the time, 10x ~9.9%.
How to verify a limbo round yourself
Rotate or end the seed pair in your account so the casino reveals the server seed it committed to. Until that happens the hash is a promise, not a proof.
Copy the revealed server seed, your client seed and the nonce of the round you want to check — the nonce is the round counter, not a timestamp.
Paste all three into the verifier above. It recomputes the HMAC chain and derives the limbo outcome the same way the operator's server did.
Compare the result with what your bet history shows. A mismatch on any single round is the only evidence of tampering that actually means something.
Check the committed hash too: hash the revealed server seed and confirm it equals the hash the casino published before you played.
Verification proves the result was not changed after you bet. It does not make limbo profitable — the ~1% house edge is applied openly, in the payout table, and it is unaffected by any of this.

Is Limbo the same as Crash?
They share the idea but not the construction — Crash adds an instant-bust rule and a different digest layout. Verify each with its own game page.
