Create a custom spinning wheel with labeled wedges for random selection and game shows.
A spin wheel is a way to make a random choice visible: every option you type becomes a wedge on a circle, and when the wheel stops, the wedge under the pointer is the winner. The draw is random; the turning and slowing are the show around that fact. What surprises most users is that the wheel has no memory - the same label can win twice in a row, and nothing about how you press the spin changes the odds.

Sushi Tacos Pizza Salad
Expected output
One of the four labels is announced as the winner (Tacos, say). With four equal wedges, each label has a 1 in 4 (25%) chance on every spin, and the same label can win again on the next spin.
The draw is random, so no single label can be promised in advance; the example states the odds the tool actually guarantees - four equal wedges, one winner per spin, independent spins - rather than a fixed result.
Each label you enter becomes one wedge, and the wedges divide the circle evenly, so four labels produce four equal quarters with a 1-in-4 chance each. The order of your list fixes the order of the wedges around the circle, and the fixed pointer decides the winner when the wheel stops. Editing the list rebuilds the wheel, so finish the list before the first spin.
Pressing the spin control sets the wheel rotating, and it coasts to a stop on its own. The winning wedge is chosen at random and the rotation only reveals that choice, so press timing, spin length, and earlier spins change nothing about the odds. Every spin is an independent draw from the current list, so the same label can win back to back.
It is the expected result, not a fault. Every spin is independent, and small lists repeat quickly: with four labels, about 91% of four-spin runs contain at least one duplicate. Over many spins the frequencies do converge toward even shares, but the wheel is never 'due' to land anywhere; believing it is due is the gambler's fallacy.
No. The winning wedge is chosen at random, and the spinning is only the reveal, so the moment you press, how long the spin lasts, or how earlier spins landed change nothing. If you need a guaranteed result, do not spin at all: pick by hand, or trim the list to the single option you want. The wheel is for draws meant to be random.
