What is a Random Number Generator?

A random number generator (RNG) picks a number (or many) where each allowed value is equally likely. ToolLove's RNG uses your browser's built-in crypto.getRandomValues() — the same quality of randomness used for security — so it's fair for contests, lucky draws, board games and PINs.
