# List Randomizer & Shuffler

> Shuffle a list into random order — for draws, pairings, running orders and sampling.

To shuffle a list, paste one item per line and the order is randomised using a Fisher-Yates shuffle. Leave the seed at zero for cryptographically random results, or set any number to get a repeatable shuffle you can reproduce and share.

## FAQ

### Is the shuffle actually random?

With the seed set to 0 it uses crypto.getRandomValues, the browser's cryptographically secure random source. With a non-zero seed it uses a deterministic generator so the same seed always produces the same order.
