How do I pick a random number with a wheel?

Set the range, from 1 to 10 at first, and press Spin. Up to 100 numbers sit on the wheel as slices; a bigger range rolls on a number drum. Turn on No repeats for a raffle or bingo, and the history shows every number drawn.

What people use it for

  • Draw raffle tickets or bingo numbers, with No repeats on so no number comes up twice.
  • Pick a student by their number on the class list.
  • Choose a page, a question, or a level at random for practice.
  • Roll a number for a board game when the dice are lost: 1 to 6, or 2 to 12.

How the spin is decided

The result is picked before the wheel moves. Your browser's built-in random number source (crypto.getRandomValues) picks one slice, and every slice has the same chance. Then the wheel turns a few times and slows down until that slice stops under the pointer. The speed, the sound, and the colors change nothing.

The pick happens in your browser, not on a server, so nobody can set the result in advance. An entry that shows up twice on the wheel, such as a name typed twice, has two chances.

Wheel or drum

Up to 100 numbers fit on the wheel, one slice each, so 1 to 10 or 1 to 100 spins as a wheel. A bigger range, such as 1 to 1,000, rolls on a number drum, because a slice that thin can't be read. Both draw the same way: each number has the same chance.

With No repeats on, each number leaves the draw once it comes up, and the wheel shows only the numbers that are left. The history lists every number in the order it came up. You can use any whole numbers from -1,000,000 to 1,000,000.

Pertanyaan

Is the number wheel random?

Yes. Your browser's random number source picks the number, and every number of the range has the same chance. The wheel only shows the pick.

Can it draw numbers without repeats?

Yes. Turn on No repeats. Each number then leaves the draw once it comes up, until every number of the range is drawn.

What is the biggest range?

Any whole numbers from -1,000,000 to 1,000,000. Up to 100 numbers fit on the wheel; a bigger range rolls on a number drum instead.

Can I share the wheel with my class?

Yes. The range and the No repeats option are in the link. The drawn numbers are not, so each person who opens it starts a new draw.

Does it work on a school computer?

It runs in any up-to-date browser, including a Chromebook, with no download and no sign-in. Once the page has loaded, a spin needs no connection.
