Decision Wheel

This isn't really a game so much as a tool that we end up using almost every Friday night to settle the "what's for dinner" argument. I built it because every random-wheel site I tried was buried under banner ads, full-screen popups, and "sign up to save your wheel" walls. Type your options into the box, hit update, spin. That's the whole thing.

A few practical notes from heavy use. Don't add too many segments — past about twelve, the wheel becomes hard to read on a phone and the result feels arbitrary even though it's not. If you're using it to pick from a long list, do a bracket-style tournament: spin to pick four, then spin those four. The result feels more satisfying and the visual reveal is better. You can also colour-bias segments by entering the same option twice if you secretly want a tilted outcome.

How the physics works

The wheel uses real angular deceleration — it picks an initial spin velocity within a range and slows over time using a fixed friction coefficient. The final segment is whatever the needle lands on; there's no fudging the result toward any particular outcome. If anyone tells you their decision wheel uses "AI" to pick, they're lying — it's just a random spin. If you like the visual style, our Plinko Pegs is from the same neon-and-particles family.
