Questions about Random Number Generator
Can I generate several random numbers without repeats?
Yes, there's an option to disable duplicates — in that case the quantity you request can't exceed the size of the chosen range.
Can I use it to run a giveaway or raffle?
Yes, with the list picker you can paste in participant names and randomly pick one or more winners.
Can I roll more than one die or coin at a time?
Yes, you can set how many dice or coins to roll in the same throw.
How random are the results?
They use the browser's cryptographic generator (crypto.getRandomValues) with rejection sampling, so no number comes up more often than another. The list picker shuffles with the Fisher–Yates algorithm, giving every participant exactly the same chance.
