转盘随机抽取器.

Is the wheel actually random?

Yes. The winner is drawn uniformly at random before the wheel moves, and the animation is then aimed to land on that segment. Deriving the winner from wherever the graphic stops is the classic bug in wheel apps - it produces off-by-one errors right on segment boundaries - so this wheel does the opposite.

How do I enter my options?

Type or paste them into the box one per line, comma separated, or both. Blank lines and stray spaces are ignored, and the wheel supports up to 100 options. Segment labels are hidden above 16 options so the wheel stays readable, but the draw still covers every entry.

Can I remove the winner after each spin?

Yes - tick "Remove the winner after each spin" and the winning entry is deleted from the list once it is announced. That gives you a drawing without replacement, which is what you want for raffles, seating order or picking teams.

Does each option have an equal chance?

Every option occupies an equal slice and is drawn with equal probability. If you want to weight an option more heavily, enter it more than once - listing a name twice on a ten-entry wheel gives it a 2-in-10 chance.

Does it work if I have motion sensitivity turned on?

Yes. If your system has "reduce motion" enabled, the spin animation is skipped and the winner is revealed immediately. The result is also announced in a live region, so screen reader users get the outcome without seeing the wheel at all.
