Random number generator online
Set the minimum and the maximum, tap Pick a number and see the result in huge digits on screen. Pick a number from 1 to 100, several at once and with no repeats.
How do I pick a random number?
Type the lowest and the highest number of the range, for example 1 and 100, say how many numbers you want and tap Pick a number. The generator uses the browser's secure random number generator, and every number in the range has the same chance. With No repeated numbers checked, no number comes out twice in the same draw.
How to use it
- Type the lowest number under Minimum and the highest under Maximum. Both are part of the draw. To pick a number from 1 to 100, leave 1 and 100.
- Under How many, say how many numbers you want at once, from 1 to 100.
- Keep No repeated numbers checked so each number comes out only once per draw. Uncheck it if the same number may come out again, like on a die.
- Tap Pick a number. The numbers spin for a moment and the result shows up in huge digits on the stage.
- Each draw is listed under Draws in this session, with the range used. Tap Clear the history to start from zero.
- If something doesn't add up, the message says what to change. For example: the maximum must be higher than the minimum.

How the number is picked
Each number comes from the browser's secure random number generator, the same one used to create passwords. The generator throws away the leftovers of the math so that no number in the range has a better chance than another.
With No repeated numbers, a draw of several numbers works like taking balls out of a bag without putting them back. With each tap on the button, the bag is full again: a number may come out again in another draw.
