The byteGenerator, float conversion and every per-game event mapping were confirmed identical to Stake.com (14 of 14 claims, research/platform/tools/tool-finesse-audit/STAKE_COM_VS_US_2026-08-17.md). Roulette is not in that confirmation set, so it has no Stake.us route yet.

How Stake.us derives a Keno result

From float to result

Ten floats are generated. Each is multiplied by the count of numbers still in the pool of 1 to 40, and the chosen number is removed before the next draw (Fisher-Yates). The house always draws 10, whatever you picked.

What to compare

Mark your picks on the board below; hits are the picks that appear in the 10 drawn numbers.

Where the seeds are

Open the bet in your history on Stake.us. 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.us

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

Does my pick count change the draw?

No. The house draws 10 numbers for every bet. Your picks only determine how many of those 10 were hits.

Why are the drawn numbers sorted?

For display. The draw order is fixed by the floats, but Keno pays on the set of hits, so order does not matter to the result.

Which Stake.us algorithm does this use?

Stake.us, Provably Fair: Game Events (identical scheme to Stake.com), read 2026-08-17. The byte stream is HMAC-SHA256 of clientSeed:nonce:round keyed by the server seed, converted to 4-byte floats, then mapped to the 10 numbers drawn.

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.
