Wheel of Fate

Most random pickers ask you to trust them. This one shows its working: give it options, choose how many draws, and it reports the distribution, the leader, and whether the lead means anything at all.

What it does

How it's built

One HTML file. No framework, no dependencies, no build step. The simulation precomputes every draw and replays the tally over roughly a second with a watchdog timer, because animation frames get throttled in a background tab and a naive implementation stalls at nine draws and never finishes.

The statistics are computed in the page: chi-square against the expected uniform distribution, with an effect-size ratio so a large sample doesn't produce a "significant" result that's one percent away from even.
