How to generate random numbers
- Type the minimum and maximum number of the range (both are included).
- Choose how many numbers you want. For a draw without repeats, turn on "No repeated numbers".
- Tap Generate. You can sort the numbers from lowest to highest.
- Tap Copy to take the list somewhere else.
What a random number generator is for
It's useful for drawing a raffle number, picking a participant by their list number, setting up a home lottery, choosing numbers for a game or simply making a decision at random.
Numbers are generated with the browser's cryptographic generator and without bias: every number in the range has the same probability.
With "No repeated numbers" it works like drawing balls from a bag: once a number comes out, it doesn't come out again.
Things to keep in mind
- It only generates whole numbers, between -999999999 and 999999999, and up to 1000 at a time.
- Without repeats, you can't ask for more numbers than the range has (for example, 10 different numbers from 1 to 5 is impossible).
- It's not an official lottery tool: it doesn't serve as proof of a legal draw.
