How the yes or no wheel works

A yes or no wheel is the quickest way to get a random yes or no answer without flipping a real coin or rolling a die. Type the question you are stuck on, press Spin the Wheel, and wait for the pointer to settle. The answer appears under the wheel together with the question you asked, so you remember what was actually decided instead of staring at a bare "Yes".

The wheel ticks as the pointer passes each slice and plays a short chime when it stops, the same sounds as our main giveaway wheel. If you are in a classroom or an office, Sound off silences it and the page remembers your choice.

The wheel is cut into six equal slices. With the default setting three of them say Yes and three say No, which is an even split. Turn on Include Maybe and the six slices become two Yes, two No and two Maybe, so each answer keeps exactly one chance in three.

There is no hidden bias, and here is why that matters

Plenty of decision wheels quietly let the page owner tilt the odds, or animate the pointer toward a slice that was picked for entertainment rather than by chance. This one does not, and the code is simple enough to describe in one sentence: the winning slice is drawn with crypto.getRandomValues, your browser's cryptographically secure random generator, before the animation begins, and the spin is then aimed at that slice.

Two details make it fair rather than just random-looking. The draw uses rejection sampling, so the leftover values that would otherwise favour the low-numbered slices are thrown away instead of wrapped around. And six slices divide evenly by both two and three, so neither the Yes and No setup nor the Maybe setup leaves a remainder. You can read the full explanation on our how our randomness works page.

Yes or no wheel or a coin flip?

The odds are identical. What differs is everything around the result.

A coin is faster, and we have an online coin flip too. A wheel is better when more than one person is watching, when the question deserves to be written down, or when you want to look at the last ten answers before deciding whether to trust this one.

When a yes or no wheel actually helps

Breaking a tie you have already argued about

Two people, two opinions, no new arguments left. Writing the question into the box forces both sides to agree on what is being asked, which is usually the harder half of the problem.

Small decisions that eat your day

Whether to reply tonight or tomorrow, whether to take the long route home. These are not worth deliberation, and handing them to a wheel costs four seconds.

In a classroom

Teachers use it for quick true or false calls, for deciding whether a class does the extra question, or as a live demonstration of probability. Spin it thirty times with the tally visible and the class watches the split wander around 50/50 without ever sitting on it, which is the whole lesson. Our classroom guide has more ideas along these lines.

When you want to find out what you were hoping for

This is the honest reason most people spin. The wheel says No, you feel a flicker of disappointment, and now you know your own answer. The wheel did its job even if you ignore it.

Questions people ask

Is the wheel really 50/50?

Yes. Six equal slices, three Yes and three No, and the winning slice drawn by your browser's secure random generator. There is no control on this page that makes one answer more likely, because adding one would make every other sentence here untrue.

Can I share my question with someone?

Press Share question and the link on your clipboard carries the question with it. Whoever opens it sees the same question above the wheel and spins it themselves.

Do you store my question?

No. It stays in your browser and in the link you choose to share. It is never sent to our servers and it is gone when you close the page.

Can I put my own answers on the wheel?

Not on this page, which is deliberately limited to yes, no and maybe. For your own choices use the giveaway wheel, where you type any list of options, or the instant draw if you would rather skip the spinning.
