Result = random(0, 1) * 360 degrees
Winner = options[floor(rotation / segmentAngle)]
Where segmentAngle = 360 / number of options

主な利点
- Fair and unbiased random selection with physics-based wheel animation that eliminates human bias
- Fully customizable options with up to 20 segments, custom labels, and vibrant segment colors
- Works as a team decision maker, name picker, giveaway selector, and daily random tool
- Free to use on any device with no downloads or sign-ups required
プロのヒント
- Use the preset templates (Yes/No, Name Picker, Days of Week) to save time setting up common scenarios
- The Long spin duration creates more dramatic reveal moments great for live streams and group events
- Check the History panel to review past spin results and ensure no one dominates random selections
避けるべきよくある間違い
- Adding duplicate options which reduce the fairness of the random selection process
- Using too many options on the wheel at once — the recommended maximum is 20 for clear visibility
- Not saving the result before spinning again — always record your winner in the history log
