Frequently asked questions
How do I pick a random number between 1 and 100?
Choose Random number, enter 1 and 100, and press Pick. Every number in the range is equally likely.
How do I draw several different numbers, like a raffle or lottery?
Tick “No repeats” and choose how many numbers you want. Each number can then appear only once.
Is it really random?

d4, d6, d8, d10, d12, d20 and d100, up to 30 at a time, with the total shown for several dice.
Can I flip many coins at once?

Can I use this for a draw or competition?
