Random Number Generator

Each draw mixes four sources of entropy: your browser's cryptographically seeded random generator, the current timestamp down to the millisecond, the path your mouse or finger has traced over this page, and (when available) your public IP address with the dots removed. The IP and timestamp make every seed unique to this moment and this connection; your cursor's path adds unpredictability that comes from your own hand rather than the machine; the browser's own randomness keeps the result unpredictable even to someone who knew all three.
