How to check a round
Find the round ID on your result receipt and use it to check the numbers’ starting point in your own browser.
After a round settles, the result receipt shows the winning number and a round ID. That ID lets anyone check the seed, the starting value HNW used to generate the round’s numbers.
Open the receipt
On the results page, follow Verified fair beneath the round ID. The link opens the verifier and runs the check for that round. If a friend sent you just the ID, paste it into Verify a round and select Verify.
Read the result
Your browser uses the round’s recorded inputs to calculate the seed again. It then rebuilds every number on the reel from that seed and checks that each locked number is the one at its stop. Checks out means every check passed, and the Checks list shows each one. The summary shows the first few characters of each value under Server seed and Your recomputed seed.
If you see Something doesn’t match, the Checks list shows which part your browser could not confirm. Use View round data (JSON) to inspect the full record. You can also expand Read the verifier code used on this page to see how the browser performed the check.
Sealed reels
A host can turn on Sealed reel under Game settings. On a sealed reel, the numbers stay hidden until everyone has stopped. Before anyone stops, the round shows a seal, a fingerprint of the seed. The seed itself is published after the last stop.
For a sealed round, the verifier also checks that the published seed matches that seal. If you played the round in this browser, it checks the seal your browser saw before the last stop too. A seed that matches the seal could not have been changed once the stops were known. While a sealed round is still being played, the verifier asks you to check back once everyone has stopped.
