About Random Number

Picking a number "between one and a hundred" is a game everyone already knows, and it is the honest way to run a raffle, choose a seat or settle who goes first when a coin has too few sides. The trick is that a person asked to pick a number is a poor randomiser - we all lean on the same favourites - so handing the draw to the browser keeps it fair.

Set the low and high bound and the draw falls somewhere between them, each value as likely as the next, both ends included. The last several draws stay on screen so you can run a short sequence without losing track, which is handy when you are picking more than one. The bounds and the history live only in this browser and reset on a refresh.

Frequently asked questions

The Range button cycles through the common ranges 1 to 10, 1 to 100, 1 to 1000 and 1 to 6. Every number in the chosen range, including both ends, is equally likely.

Each draw is independent, so a number can come up again on the next draw. The last few draws are listed so you can see the sequence as you go.
