Decision Wheel: Spin the Wheel to Decide (Free Random Picker)
A decision wheel picks one option at random from a list you type in. Each option has an equal chance (25% each with 4 options) unless you give it extra weight. Stuck on something bigger? Notice how you feel when the wheel stops.

How to use the decision wheel (in 3 steps)
Type your options, one per line, and press Spin. The wheel draws a winner at random, turns to it and shows the result with the odds it had. If you only want an answer, Quick pick works as a plain option picker or random choice picker: same fair draw, no animation, result at once.
Definition
- Decision wheel
- A decision wheel is a random picker that selects one option from a list you type in, using a spinning wheel to show the result. Some people call it a wheel of decisions or a wheel of choice.
Type or paste your options
One per line, up to 100. Blank lines are ignored and emoji work fine.
Spin, or tap Quick pick
Tap the wheel or the Spin button. On a keyboard, Enter or Space on the Spin button works too.
Read the result and check your gut
The card names the winner and its chance, then asks how you feel about it.
Make one option more likely. Give it a weight from 1 to 10 in the odds list. Weight 2 means twice the chance of weight 1.
Remove winners as you go. Turn on "Remove winner after each spin" to set a running order or narrow a shortlist.
Share it. Share wheel copies a link with your options and weights, so the group chat sees the same wheel.
Wheel of chance ideas: games, raffles, classrooms and everyday choices
A wheel of chance works for any small choice where every option is fine and someone just has to pick. Most ideas below load a preset into the wheel above with one tap, and you can edit any list before you spin.
- Food and date night. Settle "I don't mind, you pick" in five seconds with What should I eat? or What should we do tonight?
- Games. Spin Who goes first? with your players' names instead of arguing over dice.
- Giveaways and raffles. The Giveaway winner preset turns on removal, so nobody wins twice. Use full screen on a stream or a projector.
- Classrooms. Put the class list in, turn on removal and every student answers once before anyone answers twice. The Numbers mode works for students by number.
- Chores at home. Spin who takes out the trash this week. For a full weekly plan, the chore chart maker does the job better.
- Which habit to start. Can't choose between reading and a workout? Spin Which habit should I start?, or pull ideas from a bucket list generator first.
Can't decide? Use the wheel as a gut check
When you're stuck, the wheel works best as a mirror, not a judge. Spin, then notice how you feel about the result. Relief suggests you've found your answer. A sinking feeling, or the urge to spin again, may mean you wanted the other option all along.
Research on coin flips backs this up. In a 2019 paper with two studies, Mariela Jaffé, Leonie Reutner and Rainer Greifeneder describe a coin flip as a catalyst rather than a decider: it points to one option, you focus on that option, and your feelings about it get stronger, like a magnifying glass. In a 2020 follow-up of four studies with 1,135 people in total, Jaffé, Maria Douneva and Greifeneder separate the two ways people use a coin: as a fair way to settle a choice, and as a trigger for a reaction they then act on. A wheel does the same job with more options. It doesn't know what's right for you; it makes you notice what you already prefer.
| Your reaction | What it may mean | Next step |
|---|---|---|
| Relieved | Sounds like a yes | Go with it |
| Disappointed, or you want to spin again | Your gut may prefer another option | Take that feeling seriously and choose the option you hoped for |
| Neutral | Any option is probably fine | Go with the wheel and move on |
After the spin, ask yourself three quick questions:
- Did I feel relief or a sinking feeling?
- Did I want to spin again?
- What would I tell a friend in my place?
Is the wheel really random? How we pick a winner
Yes. The winner is drawn first, with your browser's cryptographic random number generator, and only then does the wheel turn to that slice. The animation decides nothing. Every option's chance is its weight divided by the total weight, so with equal weights each of 4 options has a 25% chance.
Here's the method in plain words. The draw uses crypto.getRandomValues, the Web Cryptography API's source of cryptographically strong random values, to get a 32-bit number. A simple shortcut, the remainder after dividing by the number of options, would give some options a sliver more chance. That's called modulo bias: map the numbers 0 to 9 onto 4 options that way and two options get three chances each while the other two get only two. With 32-bit numbers the gap is tiny (2 to the power of 32 is 4,294,967,296, so for 7 options, four of them would get one extra value out of about 4.29 billion), but the wheel removes it anyway with rejection sampling: it throws away the few values at the top that don't divide evenly and draws again. The stopping point is random too, somewhere between 10% and 90% of the winning slice, so it never lands on a line.
| Your wheel | Chance per option |
|---|---|
| Pizza, Sushi, Tacos, Salad (all weight 1) | 25% each |
| Pizza at weight 2, the other three at weight 1 | Pizza 40%, the others 20% each |
| Pizza typed three times, Sushi once | Pizza 75% in total, Sushi 25% |
| 4 options, removing each winner | 25% each, then 33.3%, then 50% |
We also tested it. In November 2026 we ran 100,000 spins of a 4-option wheel through the tool's own drawing code, with Node.js's built-in version of the same Web Crypto generator. The four options won 25,056, 25,005, 25,067 and 24,872 times.

Arithmetic: the square root of 0.25 × 0.75 ÷ 100,000
Don't take our word for it: "Check the odds yourself" under the wheel runs 10,000 spins of your own wheel in your browser. One thing the wheel never does is correct for streaks. The same option can win twice in a row, because that's what real chance does.
Yes or no wheel and number wheel
For a quick call, switch the wheel to Yes or no: it's a 50/50 draw, or 33.3% each once you add Maybe. For a random number, switch to Numbers, set the lowest and highest number (1 to 10 by default, both included) and every number gets the same chance.
| Mode | Chance per result | Good for |
|---|---|---|
| Yes or no | 50% | A quick go or no go |
| Yes, no or maybe | 33.3% | When "not now" is a real answer |
| Numbers 1 to 6 | 16.7% | A die when you can't find one |
| Numbers 1 to 10 | 10% | Picking a number for a game |
| Numbers 1 to 100 | 1% | A raffle ticket or a student by number |
The number wheel goes up to 10,000 numbers (above 100 it shows only the result). With winner removal on, every number comes up once, handy for raffle tickets. Torn on a yes or no? Try best of three. Unlike a coin flip, a wheel can hold more than two options and weight them.
When not to let a wheel decide
Spin for choices that are low in stakes and easy to undo: dinner, a movie, who goes first. Think a choice through yourself when it's high in stakes or hard to reverse, like your health, money, legal matters or a relationship. There, use the wheel as a gut check at most, never as the decider.
| The choice | Easy to undo | Hard to undo |
|---|---|---|
| Low stakes | Spin. Example: tacos or sushi | Spin as a gut check. Example: which weekend trip to book |
| High stakes | Spin as a gut check. Example: trying a new gym for a month | Think it through. Example: changing careers or moving cities |
For a big choice, write the options down after your gut check: what each one costs and gives you, and what's urgent versus important. The Eisenhower Matrix maker helps with that for tasks and priorities. For health, money or legal decisions, talk to a professional.
If a decision feels overwhelming or you're in crisis, talk to someone you trust, or call or text 988 to reach the 988 Suicide and Crisis Lifeline (US). It's free, confidential and open 24/7 by call, text or chat. In an emergency, call 911.
Make fewer decisions with a daily routine
The easiest decision is the one you don't have to make. When to work out, what to do first, whether to read tonight: those small choices fade once each habit has a fixed place and a fixed order in your morning or evening routine, so there is nothing left to spin for.
That's how Greatr is built. You stack small habits in a fixed order, tap Play and run your routine one habit at a time, and every habit earns XP while your streak grows. How long until it feels automatic? In a 2010 study of 96 volunteers, Phillippa Lally and colleagues found a median of 66 days, with a range of 18 to 254 days, so give it time.
Not sure which habit to start with? Spin Which habit should I start? and put the winner into tomorrow's routine. Want more choices first?

Frequently asked questions
How does a decision wheel work?
You type your options, one per line, and spin. The wheel draws a winner at random first, then turns to that slice, so what you see is what was drawn. With equal weights every option has the same chance: 25% each for 4 options. Quick pick skips the animation and shows the result at once.
Is the decision wheel really random?
Yes. The winner comes from your browser's cryptographic random number generator (crypto.getRandomValues), with rejection sampling so no option gets even a sliver of extra chance. In our test of 100,000 spins on a 4-option wheel, each option won between 24.87% and 25.07% of the time. The wheel never corrects streaks, so repeats can happen.
Can I make one option more likely to win?
Yes. Give it a weight from 1 to 10 in the odds list. Its chance is its weight divided by the total weight, so with four options and one at weight 2, that option has a 40% chance and the others 20% each. Typing an option twice also doubles its chance, and the list shows that.
How do I remove an option after it gets picked?
Turn on "Remove winner after each spin" and each winner leaves the wheel after its spin, struck through in the list. The odds of the rest update at once: 25% each for 4 options, then 33.3%, then 50%. When one option is left, the wheel says so. Reset wheel brings every option back.
What is a wheel of chance?
A wheel of chance is a spinning wheel that picks a random result, used for games, raffles, classrooms and everyday choices. This one, also called a wheel of choice or a wheel of decisions, takes your own options and shows each option's chance. For a raffle, turn on winner removal so nobody wins twice.
How do I decide when I can't choose?
Spin the wheel, then notice your reaction. Relief suggests the result is your answer. Disappointment, or the urge to spin again, may mean you want the other option. A 2019 study by Jaffé, Reutner and Greifeneder found that a coin flip works this way: it strengthens your feelings about the options rather than deciding for you.
Should I let a wheel make a big decision?
No. Spin for choices that are low in stakes and easy to undo, like dinner or a movie. For decisions about your health, money, legal matters or relationships, use the wheel as a gut check at most, write the options down and talk to a professional who knows your situation. It is not advice.
Can I share my wheel with friends or a class?
Yes. Share wheel copies a link with your options and weights in it, so anyone who opens it sees the same wheel. For a class or a stream, the full screen button shows the wheel large on a projector. Your options stay in your browser and the link: nothing is stored or sent to us.
