Every NameWheel spin is decided by crypto.getRandomValues(), the random source browsers reserve for security work. This lab runs that exact function against a wheel of your choosing, live, in front of you. Paste your own names if you like. If bias existed, this page is where it would surface.
Most randomness demos replay canned data. This lab draws fresh numbers on your machine, from your browser's own cryptographic generator, against the names you chose. Three instruments watch the run. The distribution bars should stay in a tight pack and never crown a permanent leader. The deviation gauge should drift left as the spin count climbs, because genuine randomness converges toward an even split without ever landing exactly on it. And the streak counter catches the thing human intuition gets wrong: real chance produces repeat winners in bursts, and the verdict card shows you how long a streak mathematics actually expects.
The counter above the lab is real and grows with every completed run, from every visitor, forever. NameWheel does not collect the names you test; the only thing recorded is that a run of a given size finished, and how close to even it landed.
Teachers get accused of favorites. Streamers get accused of rigging. A privacy policy paragraph convinces nobody mid-argument, but an experiment they can run themselves usually ends the discussion. Send doubters here, tell them to paste the exact names from the contested wheel, and let them press the button as many times as they like. Every run draws new numbers; the leaders shuffle; the gauge settles. That is what fair looks like.
One disclosure, because honesty is the product: PRO accounts can enable weighted entries, where Alice:3 visibly triples a slice. That is announced odds, drawn on the wheel for everyone to see, and this lab always runs with equal weights, the way the free wheel always behaves.
