Random Number Wheel

How the wheel picks a number

Every number in your Min-Max range (minus anything you've excluded) gets an equal-sized slice of the wheel. Spinning uses the same cryptographically secure, unbiased draw engine as the rest of this site (the Web Crypto API, explained in full on the true random number generator page) to choose the winning slice before the animation even starts; the spin itself is a visual effect, landing precisely on the number that was already fairly drawn, not a separate physics simulation that could favor one part of the wheel over another.

Worked example: a 20-person prize drawing, one winner per spin

Number your 20 entries 1 to 20, set Min to 1 and Max to 20, and turn on "Remove each number after it's picked". Spin once for the first prize; the winning number automatically leaves the wheel, so a second spin for a second prize can never re-pick the same person. Keep spinning until every prize has a winner, or reset the wheel at any point to start over with the full set of numbers back in play.

Worked example: excluding a few numbers before spinning

If certain numbers shouldn't be eligible (a person who already won something else, a table number that's reserved, a value you're deliberately skipping), type them into the Exclude field separated by commas, for example 3, 7, 15, before spinning. Those numbers are removed from the wheel immediately, without affecting the fairness of the remaining ones: every number still on the wheel keeps an equal-sized slice and an equal chance.

Wheel size and range limits

The wheel supports up to 100 numbers at once; each slice needs enough visible space for its label, so a wheel with hundreds or thousands of numbers would be unreadable rather than just slow. For a wider range, or if you need several numbers picked at once rather than one spin at a time, use the main random number generator instead, which supports up to 1,000 numbers per batch with the same unbiased draw engine, just without the spinning animation.

Wheel vs. the plain generator: when to use which

Both tools draw from the exact same fair, cryptographically secure engine, so the choice is purely about presentation, not accuracy:

• Use the wheel when the moment of picking matters: a live audience, a classroom, a game night, or anywhere a visible build-up to the result adds to the experience.
• Use the plain generator (homepage or the number generator quick-pick page) when you want the number instantly, need more than one at a time, need decimals, or are generating results to paste into a spreadsheet or document.
• Use "Remove each number after it's picked" on the wheel specifically when you're drawing multiple winners from the same pool and none of them should repeat; the plain generator's "No duplicates" option does the equivalent for an instant batch draw.
