Yes or no wheel

For the questions nobody wants to decide

Type the question if you want it on record, then tap the wheel or the Spin button (Enter or Space works too once it has focus). Green is yes, red is no, gold is maybe. More slices per answer make a busier wheel with longer suspense at the end; the odds stay the same.

At a game table it settles house-rule arguments in seconds: does landing on the space count, can you trade on someone else's turn, one more round or bed. Agree before the spin that the wheel's answer stands for the night.

If one spin feels too sudden for a bigger call, spin three times and go with two out of three; the history keeps the tally. And if you notice you were hoping for one answer while the wheel turned, that tells you something too.

How the answer is picked

The answer is chosen before the wheel moves. The page asks your browser's cryptographic random generator (crypto.getRandomValues) for a number and keeps it only if it divides evenly among the slices, drawing again otherwise, so no slice gets a hidden edge from rounding. Then the wheel turns several full times and stops at a random spot inside a matching slice, away from the lines. With reduced motion on, it jumps straight to the answer.

Automated tests spin it tens of thousands of times and check that yes, no and maybe each come up within a few percent of their fair share, and that the stopping angle always points at the slice that was drawn.

Questions about the wheel

Are yes and no equally likely?

Yes. Every slice has the same chance, and each answer has the same number of slices, so yes and no are each one in two (or one in three each once you add maybe). Adding more slices changes how the wheel looks, not the odds.

Does the wheel decide where it stops?

No. The answer is drawn first from your browser's cryptographic random source. The wheel is then turned so it comes to rest inside a slice showing that answer. How hard or how often you tap has no effect.

Why add a maybe?

Some questions are not really yes or no, like "should we play one more round?" when half the table is tired. A maybe slice gives the group permission to talk it over. Turn it off for a clean yes or no.

Is my question saved anywhere?

Only in this browser, next to the answer in your history, so you can look back at what you asked. It is never sent anywhere. Clear the history to remove it.
