Is a yes or no wheel really 50/50?

Yes. Three slices say Yes and three say No, so exactly half of the 360° belongs to each answer and every spin is a clean coin-flip. The slices alternate rather than sitting in two great blocks, which changes nothing about the odds — 3 out of 6 is 1 out of 2 — but stops the wheel looking like it has a favourite side.

The winning slice is chosen the moment you press the button, drawn from your browser’s cryptographic random number generator rather than a plain random() call, and the wheel then rotates to land on it. Nothing about the spin — where it started, how hard you flicked it — can move the result, which is the entire point of letting a wheel decide.

To add a third option, type it on its own line. One Maybe among the six slices gives 42.9% Yes, 42.9% No and 14.3% Maybe; a list of one Yes, one No and one Maybe gives a flat third each.

Every line you type is one equal slice, so the odds are just a counting exercise. Edit the box and the wheel re-cuts itself immediately.

What you type	Slices	Chance of Yes
Yes, No	2	50%
Yes ×3, No ×3 (default)	6	50%
Yes ×2, No	3	66.7%
Yes, No ×2	3	33.3%
Yes, No, Maybe	3	33.3%
Yes ×3, No ×3, Maybe	7	42.9%

Two things worth deciding before you spin rather than after. Say out loud what each answer commits you to, because Yes meaning two different things is how a wheel gets blamed for a bad evening. And spin once. Best of three is a way of asking until you get the answer you wanted, and the wheel will happily give it to you eventually.

For the same 50/50 with a different piece of theatre, flip a coin; for a straight contest between two people, rock paper scissors at least lets both of them feel involved.

Frequently asked questions

Why six slices instead of just two?

Purely for looks and legibility. A two-slice wheel is a semicircle that spins into a blur and lands on a half — visually it reads as a coin, and a lot of people distrust it for exactly that reason. Six alternating slices keep the same 50/50 odds while giving the pointer something to travel across. If you prefer two slices, delete four lines; the maths is identical.

Can I add a Maybe or a third option?

Type it on its own line in the entries box. Every line is one slice of equal size, so the odds are simply your line count. Six Yes/No slices plus one Maybe is 3/7, 3/7 and 1/7. If you want an even three-way split, clear the box and type Yes, No and Maybe on three lines — or two of each for a nicer-looking six-slice wheel.

How is this different from a coin flip?

Statistically it is not: both are 50/50 here. The difference is that a physical coin is not quite fair — a caught coin lands the same side up about 51% of the time — while both the wheel and our coin flip draw from the browser crypto generator and have no such bias. Choose the wheel when you might later want a third option.

Can I weight it towards Yes?

Add more Yes lines. Four Yes and two No is 66.7% Yes; five and one is 83.3%. Because each line is one equal slice, the weighting is visible on the wheel and anyone watching can count it. That transparency is deliberate — a hidden weighting slider would make the wheel useless for settling anything with another person present.

Does the wheel remember previous answers?

No. Each spin is independent, so three Yes results in a row are perfectly possible and happen roughly one time in eight. There is no balancing mechanism trying to even the score, because that would make later spins predictable from earlier ones — the definition of an unfair draw.

Is anything I type sent anywhere?

No. The entries live in your browser and in the page address, and the spin runs locally. Close the tab and they are gone. Copy the link and you have shared the exact wheel, which is also the only way to save one — bookmark the page after editing and it reloads with your options in place.

How the randomness works

The winning slice is picked by drawing random bytes from crypto.getRandomValues, your browser’s cryptographically secure generator, and mapping them onto the number of entries with rejection sampling — values that would fall outside a whole number of intervals are discarded and redrawn, which removes the modulo bias that would otherwise make the first slices marginally more likely. With six equal slices each entry holds a 1-in-6 chance, and because three of them read Yes, the answer is exactly 50/50. The result is fixed before the animation starts; the rotation is presentation, not process.

What a 50/50 answer does not tell you

A yes/no wheel is a decision device, not a judgement device. It is at its best on questions where the two options are genuinely close and the cost of deliberating further is higher than the cost of being wrong: which of two equally good films, whether to take the train or the bus, who goes first.

It has a second, sneakier use. Spin it, then notice your reaction before you act. If No comes up and you feel a small drop, you had already decided and were only looking for permission. The wheel is not answering the question in that case, it is exposing the answer you were sitting on.

What it cannot do is carry responsibility. Nobody accepts the wheel told me to for a decision with consequences for someone else, and quite right too. Keep it for ties, and use the what to eat wheel when the choice has more than two edible outcomes.
