How it works

Numbers are whole integers between Min and Max, both included, drawn with your browser's cryptographic random source (crypto.getRandomValues) so there is no modulo bias. Tick “No repeats” to draw without replacement, like pulling numbered balls from a bag, for example six lottery-style numbers from 1 to 49.

FAQ

Are the numbers truly random?

They come from the operating system's secure random generator, which is far more unpredictable than a basic Math.random() and fine for games, draws and classroom use. Do not use any website for regulated gambling or security keys.

Can I pick a number between 1 and 10?

Yes. Set Min to 1, Max to 10 and press Generate. For a dice roll use 1 to 6, for a coin flip use 1 to 2.

How many numbers can I generate at once?

Up to 1000. With “No repeats” the count cannot exceed the size of the range.

Is anything stored?

No, everything happens in your browser.
