How to Decide with a Spinning Wheel: Tips for Making Fair Random Choices

Where to eat lunch, whose turn it is to clean, who presents first. Situations where nothing gets decided while time ticks by are surprisingly common. This guide covers how to make a fair choice with a spinning wheel in your browser, how the odds work, how to give one option a better chance, and when to use a ladder lottery or dice instead.

When a spinning wheel decides faster

A spinning wheel helps when “any choice would be about as good, but deciding is what's expensive.” If debating the pros and cons won't change the outcome, handing the decision to an outside mechanism gets things moving faster.

  • Choosing a restaurant for lunch or a night out: the options are all on the table, but nobody makes the final call
  • Assigning chores like cleaning or taking out the trash: if it always lands on the same person, people complain, so you want a method everyone can accept
  • Deciding who presents or reads aloud first: waiting for a volunteer wastes time
  • Drawing for gifts or giveaways: you want the result to happen in front of everyone
  • Beating your own procrastination: force yourself to pick today's one task from your to-do list

On the other hand, it's not a good fit when the cost or responsibility differs a lot between options. A spinning wheel is a tool for getting past indecision, not for skipping judgment. If you're unsure whether to leave it to chance, ask yourself first whether you could accept the outcome you didn't want.

How to spin the wheel in your browser

No app to install and no sign-up. Enter your options and a wheel divided evenly among them is created on the spot.

  1. 1

    Enter one option per line

    Type your candidates in the input box, separated by line breaks. Blank lines are ignored automatically, so don't worry about extra line breaks in the middle or at the end. The wheel's segments update as soon as you type.

  2. 2

    Check the segments on the wheel

    The circle is divided equally by the number of options, and each segment gets its own color. Before spinning, check the labels on the wheel to make sure nothing you meant to add is missing.

  3. 3

    Press “Spin!”

    The wheel spins for about 5 seconds and gradually slows to a stop. You can't press it again while it's spinning, so there's no risk of spinning twice by accident.

  4. 4

    Read the result where it stops

    The option the pointer at the top lands on is shown as the result. To spin again, just press the button again for the next draw.

What are the odds? Number of options vs. probability

This wheel divides the circle equally by the number of options, so every option has the same chance of winning. Here's how the number of options relates to each option's probability and segment angle.

Number of optionsProbability per optionAngle per segment
250%180°
3about 33.3%120°
425%90°
6about 16.7%60°
812.5%45°
12about 8.3%30°

The more options you add, the narrower each segment gets and the harder the labels are to read. If you're spinning in front of other people, keeping it to around 8 options, or 12 at most, makes the result easier to see. With lots of candidates, narrow them down by category first and spin twice.

Spinning wheel vs. ladder lottery vs. dice

There are several tools for making random choices, and each suits different situations. Ask yourself whether you're picking just one thing or assigning something to everyone.

ToolGood atBest for
Spinning wheelPicking one option from a listChoosing a restaurant, picking one person for a duty, prize draws
Ladder lottery (amidakuji)Matching people to outcomes one-to-oneSeat changes, dividing roles, gift exchanges
DiceProducing a number from 1 to 6 on the spotBoard games, deciding turn order, penalty numbers
  • Want to give everyone a different task → ladder lottery. Spinning a wheel once per person can land on the same person twice
  • Want to narrow a list down to one → spinning wheel. The spinning animation helps everyone accept the result
  • Just need a number instead of physical dice → the dice tool. If 1 to 6 is all you need, it takes the fewest steps
  • Want to pick one person out of three or more → spinning wheel. Add one line per person and everyone has the same chance

How you write the options affects how fair the result feels

Even with the same wheel, the way you write your options changes how “settled” the decision feels. Tidy up the following before spinning and you'll have fewer arguments about the result.

  • Keep options at the same level: don't mix broad and narrow ones, like “Chinese food” and “that one ramen place”
  • Only include things you can actually do: leave out places you can't book or can't get to that day
  • Don't add “spin again”: leaving room for a redo means the mood in the room ends up deciding anyway
  • Don't abbreviate: text on the wheel gets small, so write it in a way everyone present can read and understand
  • Be consistent when spinning names: if two people share a surname, include first names too

Most importantly, agree as a group before spinning that you'll follow the result. With that agreement, one spin is enough; without it, you'll keep spinning again and again. Think of the wheel as solving not the decision itself but the time it takes to decide, and you'll use it just right. For roles that come around repeatedly, like duties, How to assign duties fairly is a better fit, and for splitting a group into teams all at once, see How to split people into teams.

FAQ

Is the spinning wheel's result biased?
Every option's segment is the same size, and the winner is chosen fresh each time with the browser's random number generator. Nothing makes a particular option come up more often, and the previous result doesn't affect the next one.
How many options can I add?
There's no limit, but the more you add, the narrower each segment gets and the smaller the text. For readability, keep it to 8–12 options; if you have more, spin in two stages.
Can I make one option more likely to win?
Yes. Write the same option on several lines and it gets that many segments, raising its chance. For example, with three options, writing one of them twice gives it two segments out of four, or 50%.
Are the options I enter saved?
No. Your input and the result are handled only within your browser and disappear when you leave the page. If you want a record, take a screenshot while the result is showing.
Does it work on a smartphone?
Yes. The input box and the wheel fit your screen width, and you can spin with a single tap. It works well for gathering around one phone to watch the result together.

What Colors Disappear Under a Red Sheet? Color Codes for Pens, Printing, and Word, and Why Text Stays Visible

You wrote the answers in orange, but they still show faintly under the red sheet. You made the text red in Word and printed it, and it didn't vanish at all. Whether text disappears under a red sheet (a red transparent film used for memorization) depends not on whether the color looks reddish, but on whether it looks exactly as bright as the paper through the sheet. This guide covers how red sheets hide text, a color-code list of colors that vanish and colors that don't, how to choose pens and markers, how to set the color in Word and Google Docs, why text stops vanishing once printed, and how to make and study with red-sheet worksheets efficiently.

Points Back vs. Discount: Which Is the Better Deal? Effective Discount Formula and Conversion Chart

“20% off” and “20% back in points” use the same number, but they don't save you the same amount. With points back, the money you pay buys both the item and the points, so converted to a discount rate it drops to about 16.7%. This guide uses concrete prices to cover the formula and conversion chart for turning a points-back rate into a discount rate, how to compare a discount combined with points back, how points earned on the pre-tax price, earning caps and expiring points shrink the real benefit, and how to count “double dipping” with credit cards and mobile payment apps.
