Random number generator

A number from 1 to 100
How we pick: your browser's secure random number generator chooses, with every number in the range equally likely. With No repeats on, each number can come up only once in a pick.
How to use the random number generator
- Type the lowest and highest numbers. Both can be picked.
- Choose how many numbers you want.
- Turn on No repeats or Smallest first if you need them.
- Press Pick, or Enter or Space. The numbers show big on the board.
Questions
Are both ends of the range included?
Yes. From 1 to 10 can pick 1, 10, or anything between, each with the same chance.
How big can the range be?
Anywhere from minus one billion to one billion, and up to 1,000 numbers at once.
Can I use it for a raffle?
For a quick draw, yes. Set the range to your ticket numbers and turn on No repeats. For winners drawn one by one with the full order kept, use the raffle draw. A draw here isn't certified, so don't use it where the law asks for an approved draw.
Is it truly random?
It uses your browser's secure random number generator, the same kind used for encryption, with rejection sampling so no number is favoured. The flicker before the result is only for show.
What are the keyboard shortcuts?
Enter or Space picks. F turns full screen on and off.
