What this wheel is for
A yes or no wheel is a two-answer picker. It does not explain the choice. It ends it. Use it for a small call you keep reopening: send the message, go out, order dessert, start the task, watch one more episode.
The page opens with Yes on one slice and No on the other. They have the same chance. You can rename both lines if the question is not yes or no. Go or Stay, Leave or Wait, and Call or Text are the same wheel with different words.
If you need more than two answers, add a line. It is no longer a yes or no wheel. It is a normal picker. For meals, use the what to eat wheel. For a person, use the wheel of names.
How to use it
Read the question out loud before you spin. A vague question makes either result feel wrong.
Click the wheel once. The slice under the pointer is the answer. The result is shown in large type, not as a prize.
If you will not accept one of the two answers, do not spin. Take that line off, or decide yourself. Spinning and then ignoring the result only restarts the argument.
Spin again only when the question is new, or when you removed an answer you refuse. The next spin does not remember the last one. Yes can come up three times in a row.
Make it yours
Change the two words. Keep them short enough to read on a slice.
Change the colors so Yes and No are easy to tell apart from across a table.
Use a longer spin when other people are watching. The wait is the point.
Weights exist if one answer should be more likely. Leave both weights at 1 for a straight yes or no. A weight of 2 against a weight of 1 is about twice the chance, and then it is no longer an even coin.
Shareable view puts the two lines in a link. Send it only to people who should see the question.
What it should not decide
Do not use it for anything you cannot undo, for a medical or legal choice, or for a dare someone did not agree to. Do not use it as a coin toss for money. It is a page on a website, not a certified draw.
Two people can still disagree with the result. The wheel only helps if both of them said they would follow it.
Is the pick fair?
With two lines and equal weight, each answer should come up about half the time over many spins. A short run will not split 50/50. Ten spins might be 7 and 3. That does not mean the wheel is stuck.
Each spin is separate. Landing on Yes last time does not make No more likely now.
The fairness test can run this same wheel thousands of times and count the two slices. The counts should sit near each other. They will not match exactly. A perfectly even split on a huge run would be the strange result.
Yes or no, or a different question
Keep Yes and No when the question really has two answers.
Rename the slices when the words should be specific. "Pizza or noodles" is clearer than forcing that question into yes or no.
Add a third line only when there is a real third option. Maybe, Later, and Ask someone else are common. Once you add them, say so. People should know it is no longer a coin.
For dinner ideas, open the what to eat wheel. For who goes first, open the wheel of names. For a party after the decision, open the truth or dare wheel.
FAQ
How does a yes or no wheel work?
You get two slices, Yes and No. You click the wheel, it spins, and the slice under the pointer is the answer. You can change the words before you spin.
Are the odds 50/50?
Only when both lines have the same weight, which they do when the page opens. Over many spins, the two counts should be close. They will not be identical. A single spin is either Yes or No, not a percentage.
Why did I get Yes three times?
Because each spin is new. Past results do not push the next one the other way. The same thing happens with a coin.
Can I add Maybe?
Yes. Add a line. Tell the room it is no longer a yes or no wheel, because Maybe now has its own chance.
Can I make Yes more likely?
Yes. Set a higher weight on Yes. Say that you did. An even question should stay at weight 1 and 1.
Can I share a yes or no wheel?
Yes. Open the shareable view and send the link. The two answers are in the link. Anyone with the link can spin it.
Does the page save my last answer?
No. Leaving the page drops the session list unless you kept a share link. There is no account, and the next visit starts from Yes and No again.
Is it free?
Yes. No signup and no payment.
When should I not use it?
When you already know the answer, when one result is unacceptable, or when the choice is medical, legal, or about money. A wheel is for a small decision both sides can live with.
