Yes or No Wheel: Spin for Your Answer

Got a yes or no question? Spin this wheel: Yes and No each hold exactly 50% of the circle (180°), and a single asterisk lets you change the odds to 70/30 or anything else you like.

How it is calculated

How the yes or no wheel works out your odds

The wheel starts with two equal slices, Yes and No. Each line in the box is a slice, and a line without an asterisk counts as 1. The chance of a slice is its weight divided by the sum of all weights. For Yes *2 and No, that gives 2 + 1 = 3 parts, so Yes has 2/3 = 66.67% and takes up 240° of the circle.

For more shades, add lines such as "Definitely", "Probably", "Probably not" and "No way", like a digital magic 8-ball.

Best of three, and how often Yes really turns up

Spinning more than once doesn't change the fairness of a 50/50 wheel, but it does change a weighted one. A best of three needs 2 or 3 Yes results, and with 70% per spin that is 3 × 0.7² × 0.3 + 0.7³ = 78.40%.

FormatYes *1, No *1Yes *2, NoYes *7, No *3
One spin50%66.67%70%
Best of three50%74.07%78.40%

With a best of five at 70%, Yes wins 83.69% of the time. Short runs are also more uneven than most people expect: on a 50/50 wheel, three Yes in a row happens 12.5% of the time, and ten spins land on exactly five Yes only 24.61% of the time. Seven or more Yes out of ten happens 17.19% of the time, with nothing wrong with the wheel.

Common mistakes with a decision wheel

The coin-toss trick, and what research says

A well-known piece of decision advice: let chance decide and notice your gut reaction the moment the result appears. Relieved? The answer fits. Disappointed? Now you know what you really wanted. The wheel doesn't replace your judgement, it reveals it.

There is research on leaving a decision to chance. In a field experiment by Steven Levitt (NBER Working Paper 22487, read on 2 November 2026), people stuck on a decision flipped a coin. On major decisions, those who made a change reported being substantially happier two and six months later, and those the coin told to change were happier at six months than those it told to stay put. The paper suggests people may be too cautious about big changes. It doesn't show that a wheel gives good advice on your own question.

Wheel or coin?

With only Yes and No on it, the wheel works out the same as an ideal coin. A real coin isn't quite ideal: in 350,757 recorded flips (Bartoš et al., read on 2 November 2026), coins landed on the side they started on 50.8% of the time. The wheel's result comes from crypto.getRandomValues(), your browser's generator of cryptographically strong random values (MDN, read on 2 November 2026), and is chosen before the animation starts, so a flick of the wrist plays no part.

The wheel also takes weights and extra answers. If you want a long series with statistics, use the coin flip. For six possible answers, a dice roller works too, and for a score from 1 to 100 there's the random number generator.

Save, share and revisit your list

Your entries are saved in this browser and never appear in the page address. “Share this wheel” copies a link that contains the list; send it to a friend or a colleague and they get the exact same wheel, with no retyping.

History, replace and remove

By default, Yes and No stay on the wheel after every spin, so the odds never change. Turn on "Remove the winning entry from the wheel" and the picked option disappears afterwards, which is handy for elimination or ordering decisions with several lines. With only Yes and No, that leaves one slice after the first spin. "Drawn so far" lists every result of the session.

Frequently asked questions

Is yes as likely as no?

Yes, both slices have exactly 50%. The randomness comes from crypto.getRandomValues(), your browser's cryptographic random number generator, and the result is fixed before the wheel starts turning.

Can I add "maybe"?

Yes, just type a new line "Maybe" into the text box. The wheel then splits into three equal slices of 33.33% automatically.

How is this different from a coin flip?

Mathematically it isn't, as long as only yes and no are on the wheel. The wheel, however, can take more answers and weights. For a series with statistics, use the coin flip.

Can I just spin the wheel for yes or no?

Yes, that's exactly what this page does: spin the wheel and get a clean yes or no, with no sign-up and no app to install.

How do I set odds like 70/30?

Add an asterisk and a number to a line: "Yes *7" and "No *3" gives 70% to 30%. Decimals work too, so "Yes *2.5" and "No" gives 71.43% to 28.57%.

Should I do best of three?

Only if you've agreed on it before the first spin. On a 50/50 wheel it changes nothing, because Yes still wins 50% of the time; at 70% per spin, it raises Yes to 78.40%.

Can I share my yes or no wheel with someone else?

Yes. “Share this wheel” copies a link that contains your entries. Just send it, and the other person sees the identical wheel.

Does this site store my entries anywhere?

Your entries stay in this browser only, and nothing is saved on a server. There's no sign-up, and a link only carries your list when you choose to share it.
