Number Wheel
A random number you can defend: 1–10 by default (36° per segment), stretchable to 1–100 (3.6° slivers), every value exactly equally likely. Those angles are computed at build time by the same engine that runs the wheel.
Spin: 1 to 10
Set a different maximum below the wheel, or edit the list directly for a custom set.
Where a fair number draw matters
Turn order in board games. Which kid picks the movie this week. Which team presents first. Countdown-style challenges ("do that many push-ups"). Picking a winner from numbered raffle stubs. In every one of those, the person who "thinks of a number" holds invisible power — the wheel takes it away from everyone equally. For classroom use, pair a number with each student and the wheel becomes a cold-call picker nobody can accuse of bias.
From 10 segments to 100
At 1–10 the wheel is readable at a glance; at 1–100 each segment is a 3.6° sliver and the labels get tiny — that is the honest geometry of cramming a hundred outcomes into one circle, and it changes nothing about fairness. Every segment, fat or thin, wins with exactly the same probability, because the pick is made from random bytes before any geometry is involved. If you need a big-range number more often than a spectacle, a glance at the result line after a reduced-motion spin gives it instantly.

Frequently asked questions
Is this better than "pick a number between 1 and 10"?
Much. People asked for a number between 1 and 10 disproportionately say 7, and almost never 1 or 10. The wheel gives each of the ten numbers exactly a 10% chance, drawn from cryptographic random bytes.
How do I change the range?
Type a maximum (2–100) into the "Numbers on the wheel" box and the list regenerates as 1 through your maximum. The list itself stays editable too — you can delete individual numbers or paste any custom set, like only even numbers.
What is modulo bias, and why does this wheel not have it?
The lazy way to make a random number — take a big random value and use its remainder — makes small numbers slightly more likely whenever the range does not divide evenly. This wheel instead draws just enough random bits and redraws whenever the value falls outside the range, so every number is exactly equally likely. The redraw loop is tested exhaustively.
Can I draw numbers without repeats, like a raffle?
Yes — eliminator mode removes each drawn number from the wheel, so spinning repeatedly deals out the range in random order with no repeats, exactly like pulling numbered balls from a bag.
