# Shuffle lines

Randomly reorder a list of lines, using a proper unbiased shuffle.

## How it works

Reorders pasted lines at random. Useful for randomising a draw order, a playlist, a question bank, or picking a winner from a list of names.

This uses a Fisher–Yates shuffle driven by the browser’s cryptographic random number generator. That matters more than it sounds: the obvious way to shuffle a list — sorting it with a random comparator — produces a measurably biased result, with some orderings far more likely than others. Fisher–Yates gives every permutation equal probability.

Because randomness is genuine, results will sometimes look unshuffled. A few items staying near their original position is expected, not a bug.

## Common questions

### Is this properly random?

Yes. It uses a Fisher–Yates shuffle with the browser’s cryptographic random number generator, so every possible order is equally likely.

### Why did some lines barely move?

Because the shuffle is genuinely random. Real randomness produces runs and near-misses; a result that always looks thoroughly mixed would be the suspicious one.
