Frequently Asked Questions

Is it really random?

Yes. Every whole number in your range has an equal chance. Each one comes from your browser’s cryptographically secure random number generator, and the page draws again whenever a draw would favor part of the range, so a wide range is as even as a narrow one.

Can I avoid repeats?

Yes. Turn on No repeats and no number comes up twice in the same result, like pulling numbered slips from a hat. If you ask for more numbers than your range holds, the page says so. Each press of Generate is a fresh draw, so a number can come back next time.

Can I pick several numbers at once?

Yes, up to 100 at a time. Set How many and press Generate. Sort puts them in order, and Copy lets you paste them into a list or a message.

Can I show it on a projector?

Yes. Open the page on the classroom screen and press Generate. One number shows very large, so the back row can read it, and your browser’s zoom makes a long list bigger too.

How do I pick a random number from 1 to 100?

The page starts that way, so just press Generate. For 1 to 10 or 1 to 1000, choose that range first, or type any other.

What can I use it for?

Class games, who goes first, picking a page or a seat, and a math warm-up. For a giveaway number, give each person a number and generate one.

Can I use negative numbers?

Yes. Lowest and Highest take any whole numbers from -1,000,000 to 1,000,000, so -10 to 10 works. Decimals don’t.

Are my numbers saved?

No. The numbers are picked in your browser and nothing about them is sent to us. Last results are gone when you reload or leave the page.

Is it free?

Yes. There’s no sign-up and nothing to install.
