How to use it
- Type your question in the box (optional). It appears above the wheel, which is handy on a projector or in a screenshot.
- Press Spin, tap the wheel or press Space.
- Read the answer. Press Spin again for best two out of three, or turn on Include “Maybe” for a third option.
When a yes or no wheel helps
Some decisions don’t deserve ten minutes of back-and-forth. Order pizza or cook? Watch one more episode? Go for a run now or after lunch? When both options are reasonable, a coin toss or a wheel settles it instantly and nobody has to be the one who decided. A spinning wheel has an advantage over a coin: everyone can watch the result build up, and it’s much easier to see on a phone held up for the group or on a classroom screen.
Ideas for the classroom and for groups
- Quick polls with a twist. Ask “Do we do the quiz today?” and let the wheel answer in front of the class. Students accept the outcome because they saw it happen.
- True or false practice. Read a statement, let students commit to an answer, then spin to decide who explains their reasoning first.
- Party games. Truth or dare, “would you rather” follow-ups, or deciding whether the loser of a round has to do a forfeit.
- Streams and videos. Viewers love watching the wheel slow down. Type the question so it shows above the wheel and appears in clips and screenshots.
How the answer is chosen
The wheel is split into 12 slices that alternate “Yes” and “No”, six of each. When you press Spin, the page first picks one slice using your browser’s cryptographically secure random number generator (crypto.getRandomValues), the same kind of randomness used for security keys. Only then does the animation start, and it is calculated to slow down and stop inside that slice. Nothing about when or how you click changes the answer.
If you turn on “Maybe”, the wheel switches to four slices each of “Yes”, “No” and “Maybe”, which keeps every answer at exactly one in three. We check the odds automatically: a test spins the wheel 100,000 times and confirms “Yes” comes up between 49% and 51% of the time.
A little decision tip
Before you spin, notice which answer you’re secretly hoping for. When the wheel stops, pay attention to your first reaction. Relief or disappointment is often clearer than any pros-and-cons list, and it’s a perfectly good reason to spin again or to go with your gut.
Frequently asked questions
Is the yes or no wheel really 50/50?
Yes. The wheel has 12 slices, six “Yes” and six “No”, and the result is drawn with your browser’s cryptographic random generator before the wheel starts turning. The animation is then calculated to stop on that slice. With “Maybe” turned on there are four slices of each answer, so each one has exactly a one-in-three chance.
Why are there so many slices instead of just two halves?
It looks and sounds more like a real prize wheel, with the pointer clicking past several slices before it stops. It doesn’t change the odds: every answer always has the same number of slices.
Can I add “Maybe”?
Yes. Tick “Include Maybe” in the panel. Your choice is remembered on this device for next time.
Does my question get saved or sent anywhere?
No. The question only appears on your screen and in this session’s list of answers. Nothing is sent to a server, and the list disappears when you close the page.
Is this a good way to make real decisions?
It is a good way to break a tie when both options are fine, or to find out what you were hoping for. If you feel disappointed by the answer, that tells you something too. For anything important, treat the wheel as a nudge, not advice.
