Stake Limbo Verifier

Recompute the Limbo multiplier for one bet on Stake from the server seed, client seed and nonce. Same HMAC-SHA256 stream the operator publishes, run in your browser.

How Stake derives a Limbo result

From float to result

The float is scaled by the maximum multiplier and the 1% house edge, then inverted onto a hyperbolic curve and floored to two decimals. Results below 1.00 are consolidated to 1.00.

What to compare

Compare the multiplier in your bet history with the one below.

Where the seeds are

Open the bet in your history on Stake. The client seed and nonce show immediately. The unhashed server seed appears only after you rotate your seed pair, so rotate first, then verify every bet from the old pair.

The byte stream, Stake

bytes = HMAC_SHA256(key = serverSeed, msg = clientSeed:nonce:round) // round starts at 0float = b0/256 + b1/256^2 + b2/256^3 + b3/256^4 // 4 bytes per floatresult = game event mapping applied to the floats, in order

Frequently Asked Questions

Why does the curve give so many results near 1.00x?

The inversion makes P(result ≥ T) = 0.99 / T for any target T. Half of all results land below 1.98x; that is the shape of the game, not a defect in the seed.

Is the house edge in the seed?

No. The seed produces the float; the 0.99 factor is applied in the conversion. A different edge would change every multiplier by the same proportion.

Which Stake algorithm does this use?

Stake, Provably Fair: Game Events, read 2026-09-20. The byte stream is HMAC-SHA256 of clientSeed:nonce:round keyed by the server seed, converted to 4-byte floats, then mapped to the multiplier.

Do my seeds leave the browser?

No. The HMAC and SHA-256 run with the Web Crypto API on your device. The share link carries the seeds only because you copied it.
