Quick answers about randomness, customization, saving, and privacy.
Randomness
Is the wheel really random?▼
Yes. We use crypto.getRandomValues(), a cryptographically secure function built into modern browsers that draws entropy from hardware timings, mouse movements, and keyboard delays — not Math.random().
How come I got the same result twice?▼
Each spin is a completely independent event — past results have zero influence on the next outcome, just like flipping a coin. If you want to prevent repeat winners, remove the winner after each spin.
Is the Shuffle button really random?▼
Yes. It uses the Durstenfeld variant of the Fisher-Yates shuffle. Because it's truly random, there's no guarantee every item moves, and shuffling multiple times doesn't increase randomness.
How to use
How do I add entries?▼
Type or paste names in the entry list on the right. Each line becomes one entry. You can also use the checkbox next to each entry to include or exclude it from the spin.
How do I spin the wheel?▼
Click anywhere on the wheel, or press Ctrl+Enter on your keyboard.
How many entries can I put on the wheel?▼
Up to 1,000 entries can be displayed at once. If you enter more, names are randomly sampled so every entry still has an equal chance of winning.
Customization
Can I customize the wheel colors?▼
Yes. Click Customize → Appearance to choose a color theme, set individual slot colors, add a center image, change the page background, and toggle the gradient effect.
Can I change how long the wheel spins?▼
Yes. Click Customize → During spin to adjust the spin duration.
Can I change the sound effects?▼
Yes. Click Customize → During spin or After spin to pick from a range of sounds and adjust the volume. You can also turn off sound entirely.
Saving & Sharing
How do I save my wheel?▼
Click Share in the toolbar to generate a shareable link that encodes your wheel. You can also open a previously exported JSON file with the Open button.
Are my entries saved automatically?▼
Yes. Your wheels and settings are saved in your browser's local storage and restored when you reopen the page.
How does the share link work?▼
The share link encodes your wheel's entries, colors, and title directly in the URL. No data is stored on our servers — anyone with the link can open and spin the wheel.
Privacy & Data
Do you store my wheel data?▼
No. All your wheel data lives in your browser's local storage. We never transmit or store your entries on our servers.
Do you use cookies?▼
We use only essential browser storage (localStorage) to remember your wheel and settings between sessions. We do not use advertising or tracking cookies.
