Read from the Wayback snapshot of 2025-07-19 (the live page challenges non-browser fetches); saved at research/casinos/stake/evidence/provably-fair-game-events-wayback-20250719.txt. Crash is verified on its per-seed curve only: live multiplayer Crash rounds come from a public hash chain, not your seed pair.

How Stake derives a Wheel result

From float to result

One float multiplied by the segment count gives the segment index. The multiplier is read from the operator's published payout table for that segment count and risk level.

What to compare

Compare the segment and multiplier with the spin in your bet history.

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.

Frequently Asked Questions

Why does the multiplier depend on the risk level?

The wheel is the same; the payout table under each segment changes with risk. Each published table averages 0.99 per spin.

What if my wheel has a segment count that is not listed?

Then this page shows the segment only. It never invents a multiplier for a table the operator has not published.

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 landing segment and 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.
