1. Create the wheel
Choose 2–10 sections and an inclusive whole-number range. The default is six unique numbers from 0–99. Regenerate creates a fresh sample. If your range has too few values, enlarge it, reduce the section count, or enable duplicates.
2. Customize when needed
Open Customize wheel for custom labels, manually edited numbers, sound, and duration. The number of nonempty lines must match the section count. Apply your changes before sharing or spinning.
3. Spin
The browser uses its cryptographic random source with rejection sampling to avoid modulo bias. A winning section is chosen first. The wheel then accelerates and slows to that section’s centre. Speed changes animation timing only. Reduced-motion mode shows the result immediately.
4. Keep or share the result
Copy the selected value or the most recent twenty spins. History stays in your current browser session. Shared links include settings and values, but not history. Repeated spins choose from the current wheel; regenerate to sample the number range again.
