Choose a classroom activity
Put review topics, stations, or warm-ups on a projected wheel so the available choices stay visible before the spin.
Wheel Spinner
Turn a list of text options into a visible decision wheel. Adjust the weights, check the slice labels, and spin when everyone is ready.
Presentation
1 · Build the wheel
Paste up to 50 complete choices, one per line. Then adjust any odds below and spin from the center.
6 available for the next spin · 0 set aside
Wheel
Wheel ready.
The wheel animation only reveals the selected result; it does not influence the draw.
What this tool does
A wheel spinner is a random-choice tool that maps each option to a visible slice and animates toward a result that has already been selected by the tool.
Visible decisions
Ways to use the wheel spinner
Run a party or game round
Use names, challenges, or teams as slices and remove a selected option when the next round should use the remaining set.
Make a transparent weighted choice
Give an option more or less space only when that weighting is intentional, then show the proportions to everyone involved.
Instructions
How to build and spin a wheel
Add the options
Enter one option per line. Longer names wrap when the slice has enough room, while distinct labels keep the result easy to identify.
Review the weights
Keep equal weights for an even choice, or change them deliberately and verify the visible slice proportions before spinning.
Choose the after-spin behavior
Decide whether a result stays available, is removed from later spins, or can be selected again.
Spin and present the result
Start the spin, let the animation reveal the precomputed choice, and choose Present when the wheel needs to be seen across a room.
Troubleshooting
When the wheel needs attention
The wheel has fewer than two usable options
When: Blank lines or removed entries leave zero or one active option.
Why: A spin cannot express a choice unless at least two distinct options remain.
Try: Add another option or restore a removed entry before spinning again.
A weight is zero or invalid
When: An option has a negative, nonnumeric, or unusable weight.
Why: Invalid weights cannot be converted into reliable probabilities, while a zero-weight option can never win.
Try: Use positive numeric weights and review every slice before the next spin.
The slice labels are difficult to read
When: The wheel has many options, or several option names are long.
Why: Longer labels wrap when space permits, but narrow slices leave less room for readable text.
Try: Shorten repeated wording, use a distinct label, or split a large list across smaller wheels.
Trust
Weights, animation, and privacy
The animation does not choose the winner
The tool selects a result first, and the wheel animation only travels to that already-computed result.
- Equal positive weights give active options equal probability; unequal weights change the probability in the same proportions shown on the wheel.
- Removing a result changes the next spin's option set, so later spins do not use the original distribution.
- A visual wheel is useful for transparency, but it is not an independently audited or third-party-verifiable draw.
Options are not saved
Your options, weights, and results are used for the current wheel and are not saved by Random 42.
- You do not need an account to build or spin a wheel.
- Random 42 does not save your options, wheel settings, or result history.
- Refreshing the tool clears the active wheel and its result history.
Boundaries
What this wheel does not prove
Use the wheel for ordinary, low-risk choices
This wheel is not a verified raffle service, a legal decision process, or evidence that a weighted choice was appropriate.
Review before you use the result
- Do not use it as proof of an audited winner selection or regulated lottery draw.
- The tool does not decide whether weights are fair; the person configuring the wheel is responsible for explaining them.
- A crowded wheel can make long labels harder to read, so use shorter names or fewer options for a clearer display.
FAQ
Frequently asked questions
Is every wheel slice equally likely?
Only when every active option has the same positive weight. If weights differ, the chance of each option follows the visible weighting.
Does the spinning animation determine the result?
No. Random 42 computes the choice first and then animates the wheel toward that result, so frame rate and animation timing do not pick the winner.
Can I stop a choice from appearing again?
Yes. Remove the selected option after a spin when the next result should come only from the remaining entries.
How does the wheel display long option names?
Long labels wrap onto multiple lines when space allows. On crowded wheels, shorten the labels or split the list so each slice stays easy to read.
