How the yes or no wheel decides
The wheel is a random picker with two answers. When you press Spin, the page asks your browser's cryptographic random number generator for one number and uses it to pick a slice. Every slice is the same size and gets the same chance, so with the default 2 segments the odds are 50% Yes and 50% No. Only then does the wheel start turning. It slows down over about four and a half seconds and stops with the chosen slice under the pointer. A random point inside that slice is picked too, so the wheel does not always stop on the same spot.
Because the answer is fixed before the first frame of the animation, nothing you do changes it. Pressing harder, pressing twice or spinning while the wheel is still moving makes no difference. The ticking sound follows the slices as they pass the pointer, and the chime and confetti come at the end. Both are optional, and confetti stays off when your system asks for reduced motion.
More segments do not change the odds as long as every answer has the same number of slices. A wheel with 6 segments that alternate Yes and No is still 50/50; it only looks busier and ticks more often. The line under the segment picker shows the share of each answer, so you can see when the slices are uneven: with 3 segments and only Yes and No, Yes gets two slices and a 67% chance. If you want that, keep it. If not, pick an even number or turn on Maybe, which gives each of the three answers one slice.
Maybe, more answers and your own labels
Include Maybe when a plain yes or no feels too harsh. The wheel then cycles Yes, No, Maybe, and the segment count jumps to a multiple of three so every answer stays equal. For other questions, type your own labels separated by slashes: "Now / Later / Never" for a task you keep putting off, "Pizza / Sushi / Tacos" for dinner, or "Yes / No / Ask again" for the classic fortune feel. Up to 12 labels fit on the wheel, and the counter under the result tracks each of them for the rest of the session.
Copy link puts the segment count, the Maybe setting and your labels into the address. Open it on another device, pin it in a chat or post it for a class, and the same wheel is ready to spin there. The link holds only the settings, never your spin history.
Ideas for using the decision maker
- Quick choices: go out or stay in, order dessert or not, answer the message now or tomorrow. One spin and the question is settled.
- Classroom: spin before a quiz to decide whether homework is checked today, pick who answers first, or turn a dull review into a game by letting the wheel decide which team gets the next question.
- Games and parties: use it as a truth or dare starter with "Truth / Dare" labels, or as a fortune wheel with "Yes / No / Ask again" on a big screen in fullscreen mode.
- Streams and videos: fullscreen hides everything but the wheel and the answer, so viewers can follow along on a phone or a projector.
- Tie breaks: two people, two opinions, one spin. Nobody can blame the other for the outcome.
If you need a wheel with many names instead of answers, the wheel spinner takes up to 500 entries and can remove each winner after a spin. The random name picker draws several names at once without the wheel, and the dice roller covers anything with more than a handful of outcomes.
A coin flip is just as fair
Honest note: with two segments, the yes no generator and a coin flip are the same thing. Both pick one of two outcomes with equal chance from the same random source, and both forget every round before the next one. Five No results in a row do not make Yes more likely on the sixth spin. The wheel wins on fun, on the Maybe option and on custom labels; the coin wins on speed, and its page keeps running stats over hundreds of flips. Use whichever you enjoy more.
How to use the yes or no wheel
- 1Ask your question out loud, then press Spin or hit Space. The wheel turns for a few seconds and the answer appears below it.
- 2Want a third option? Turn on Include Maybe, or type your own answers into the labels field, separated by slashes.
- 3Check the Yes and No count under the result if you spin several times, and press Copy link to share your wheel with its settings.
Frequently asked questions
Is the yes or no wheel really random?
Yes. Before the wheel starts moving, the result is drawn with crypto.getRandomValues, the cryptographic random number generator in your browser. Every slice has exactly the same chance, and the animation only lands on the slice that was already picked. Nothing about how fast you press or when you press changes the answer.
Can I add a Maybe?
Turn on "Include Maybe". The wheel then cycles through Yes, No and Maybe, so with 3, 6, 9 or 12 segments each answer gets exactly one third. With a different number of segments the odds under the wheel show you who gets more slices.
Can I use my own answers instead of Yes and No?
Type them into the labels field, separated by slashes, like "Yes / No / Ask again" or "Now / Later / Never". Up to 12 labels fit on the wheel. The labels and the segment count go into the share link, so you can send a wheel with your own answers to someone else.
Is a coin flip just as fair?
Yes. A wheel with two equal segments and a coin flip are the same random draw: two outcomes, 50% each, no memory between rounds. The wheel is more fun to watch and can hold a Maybe or more answers, which is why it exists. If you only need heads or tails, the coin flip tool is quicker.
Does the wheel remember my spins?
The Yes and No counts under the wheel add up only while the page is open. Reload the page or press Reset count and they start from zero again. Nothing is stored on a server, and nothing leaves your device except the share link you copy yourself.
