Frequently Asked Questions
Our generator uses your browser built-in cryptographic random number function (crypto.getRandomValues) which produces cryptographically secure random numbers — the same quality used for security applications.
Common uses include lottery and raffle draws, board game decisions, statistical sampling, choosing a random winner, generating test data, and resolving disputes by leaving the decision to chance.
Pseudorandom numbers are generated by an algorithm that produces numbers that look random but are mathematically deterministic. True random numbers come from physical processes. For most practical purposes, a good pseudorandom generator is sufficient.
Yes. Set the minimum and maximum values to define your range. For example to simulate a dice roll set min to 1 and max to 6. To pick a random month set min to 1 and max to 12.
