🎡 Spin Wheel

How to play

A decision wheel you fill with your own options. It opens with eight food choices; spin it and whichever segment sits under the pointer at the top when it stops is the result. Edit the list to use it for anything you need picked at random.

• The wheel, or the centre button — click either to spin. Both are ignored while the wheel is already turning, or if fewer than two options remain.
• Option tag — click a tag under the wheel to remove that option and redraw the wheel.
• Add field and Add button — type an option and click Add, or press Enter in the field. Blank entries are ignored and the wheel caps at ten options.

Scoring

There is no score. The output is a single winner per spin. Segments are always equal in size, so with n options each has exactly a 1 in n chance regardless of how the list is ordered or coloured. A spin starts somewhere between 20 and 35 degrees per frame and slows by 1.5 percent each frame until it drops below 0.2, at which point the wheel stops and the segment at the pointer is announced. Labels longer than twelve characters are shortened with an ellipsis on the wheel face, though the full text stays in the tag list below.

Tips

• Remove options as they get used and the odds redistribute automatically, which makes this a workable way to draw names without repeats.
• Ten is a hard ceiling. Past about eight the labels shrink and get clipped, so short names read better.
• The result is genuinely uniform. Spinning again because you did not like the answer is fine, but it does not make any option more likely next time.
