About the yes or no wheel
The wheel has three Yes slices and three No slices, set in turn. Three of six slices is exactly half, so each answer comes up 50% of the time.
Switch to “Yes, No, Maybe” and the wheel changes to two slices of each answer: a one in three chance for Yes, No and Maybe alike.
You can also edit the list. Add a second Maybe, or replace the words with two real choices, and the odds line under the wheel recalculates.
When a yes or no wheel helps
- Small decisions that are not worth ten minutes of debate: dessert or no dessert, one more episode or bed.
- A classroom warm-up: students predict the answer, then spin.
- A tie-breaker when a vote ends even.
- A game of yes-or-no questions where the wheel is the “oracle”.
How to use the wheel
- Type or paste your options, one per line. The wheel redraws as you type.
- Press Spin, click the wheel, or press Ctrl+Enter while you are in the list.
- Read the pick. Remove it from the wheel if nobody should be picked twice, then spin again.
How the pick is made
Before the wheel moves, your browser draws one slice at random with crypto.getRandomValues, the same generator browsers use for security keys. Every slice has the same chance. The spin you watch only plays that result out.
Nothing about the animation changes the outcome: not how hard you click, not how long the wheel turns, not the size of your screen. The pointer always stops inside a slice, never on a line.
Your list stays in your browser. A link you copy carries the list inside the link itself, so nothing is uploaded.
Questions about the yes or no wheel
- Is the yes or no wheel really 50/50?
- Yes. There are three Yes slices and three No slices of equal size, and every slice has the same chance, so each answer has a 50% chance on every spin.
- Why are there six slices instead of two?
- Six alternating slices make the spin easier to follow than two half-circles. The odds are the same: half the wheel is Yes and half is No.
- Can I add a Maybe?
- Yes. Choose “Yes, No, Maybe” above the list. The wheel then has two slices of each answer, so each one has a 33.3% chance.
- Does the last answer affect the next one?
- No. Every spin is independent. Three Yes answers in a row do not make a No more likely on the next spin.
