Using Entries, Results and Settings

Entries: set up the round

Use the controls available for this tool to edit choices, set a range or choose game rules. Review prompts and repeat settings before spinning. The Sound effects switch is below these controls.

Results: review your history

Read previous selections, newest first, and use Clear history when you want an empty list. This leaves the active choices and no-repeat pool intact.

Settings: choose the look and sound

Choose a wheel theme, select a winning sound and preview it. The Sound effects switch here stays synchronized with Entries. Colors and sounds do not change selection odds.

Wheel controls FAQ

Where can I find or clear previous results?

Open Results to see the newest selections first. Clear history removes that list; it does not restore removed winners or reset a no-repeat round. Use the tool’s reset control when you want to start a new round.

How do I change colors or turn sound off?

Open Settings to choose a theme and winning sound. Sound effects is also available in Entries; both switches control the same setting. Turning sound off mutes wheel clicks and the winning sound. Choosing No winning sound only mutes the celebration. Your sound preference is remembered for this English tool in this browser when browser storage is available.

Do themes change the chance of winning?

No. Themes only change appearance. Two-outcome wheels use two colors and three-outcome wheels use three. Repeated labels share a color in the selected theme. Entries, repeated slices and any weights still determine the odds.

About this tool

Create a Wheel With Exact Percentages

A percentage wheel makes the probability of every outcome visible. Enter positive chance values and the tool automatically normalizes them to 100%, then sizes every wheel segment to match the calculated odds.

The default 5, 25, and 70 values already total 100%. If your edited values total something else, the displayed percentages show the exact normalized chances used for the next spin, so the tool never hides or guesses at the calculation.

How to Use Percentage Wheel Spinner

Add your outcomes

Create at least two rows and enter a distinct label for each outcome.

Set the chance values

Enter positive values and review the live percentage displayed beside every outcome.

Spin and review

Spin the proportional wheel, then review the winner and recent-result history.

Real Examples

5%, 25%, and 70% prize wheel

Set Grand Prize to 5, Runner-up to 25, and Try Again to 70 so the visible slices match those exact chances.

Frequently Asked Questions

Do my entered values have to equal 100?

No. The tool normalizes every positive value and clearly displays the exact percentage used for each outcome.

Can an outcome have a 0% chance?

Enter a positive value for any active outcome. Remove an outcome when you do not want it to appear on the wheel.

Why do session results differ from my percentages?

Random samples naturally vary. Configured percentages describe long-run probability, not a guaranteed result count in a short session.

Where is the latest winner, and what does Clear history do?

The selected outcome appears below the wheel as soon as the spin finishes. Results holds earlier picks. Clear history removes those records without restoring used outcomes in a no-repeat round; use Reset round to restore the pool.
