How it Works

The Random Wheel uses a pseudo-random number generator to simulate real physical spinning physics.

1. Equal Distribution: The wheel automatically divides the 360-degree circle into equal sectors based on the number of inputs.
2. Random Spin: When you click spin, the program generates a random angle (usually including multiple full rotations for suspense) and animates the deceleration.
3. Precise Calculation: Once stopped, the algorithm calculates the winning sector based on the final angle and pointer position.

Use Cases

Decision Making

What to eat for lunch? Where to go this weekend? Who does the dishes? Let fate decide!

Events & Raffles

Perfect for lucky draws, giveaways, or picking a random winner from a list of names.

Classroom Activities

Teachers can use it to pick students for questions randomly or assign groups fairly.

Frequently Asked Questions

Is it truly random?

Yes. We use JavaScript's standard `Math.random()` function to generate random angles, which provides sufficient randomness for entertainment and decision-making purposes.

How many options can I add?

There is no hard limit. However, for the best visual experience, we recommend between 2 and 30 options. Too many options result in very thin slices where text is hard to read.

Can I rig the result?

No. This tool is designed for fair, random selection. We do not support setting weights or pre-determining winners.

Is my data saved?

No. All data exists only in your current browser session. If you refresh or close the page, your list will be lost. Please save important lists locally.

Does it work on mobile?

Yes. The tool is fully responsive and works smoothly on iOS and Android browsers. The wheel scales to fit your screen.

How do I remove options?

Simply delete the line of text from the input box on the left. The wheel updates instantly to reflect the changes.

Can I customize colors?

Currently, the wheel automatically assigns a palette of high-contrast colors. Manual color customization is not supported in this version.

Does the wheel always land in the same spot?

Visually yes, but the rotation value accumulates. It spins multiple full rotations plus a random offset each time, ensuring random outcomes.
