Random number generator
Calculator
The calculator needs JavaScript. The tables below give the same numbers for common cases.
How it is worked out
- Each number is drawn with equal chance from 1 to 100 (100 values), using your browser's secure random source.
- Change any box to draw a new set.
How to use it
Pick a minimum, a maximum and how many numbers you want. Every whole number in the range has the same chance each draw. Choose "No repeats" to draw different numbers, as for a lottery pick or a raffle.
The numbers come from your browser's secure random source (crypto.getRandomValues) with an unbiased method, so they are suitable for games, sampling and picking winners. They are generated on your device and are not stored.
