The unbiased arbiter
When the class is split 50/50, a random decision ends the debate without an authority figure taking sides. The wheel picks YES or NO with exactly equal probability using crypto.getRandomValues — and the slow, ticking spin makes the reveal a tiny shared moment.
Customize the slices for any binary (or ternary) choice: Yes / No / Maybe, Inside recess / Outside recess, Read / Draw / Game. Looking for more options instead of two? Try the food wheel or the movie wheel.
FAQ
How does the yes or no wheel work?
Press SPIN — the wheel decelerates and lands on YES or NO with equal probability. Add a third slice like “Ask again” if you like.
Is it 50/50?
Yes — each slice is equally likely, chosen with the browser's cryptographic random source. See the live fairness test.
Can I customize it?
Yes — the entries box is fully editable. Common variants: Yes/No/Maybe, Play/Rest/Read, or two lunch options. The wheel is just a fair coin with more personality.
Who uses a yes/no wheel?
Teachers resolving classroom debates (“do we read outside?”), families settling “what's for dinner”, streamers engaging chat, and anyone who wants an unbiased arbiter.
