Random & Fun

Shuffle a list fairly

Paste a list and get it back in a random order — a real shuffle, where every possible ordering is equally likely.

Fisher-Yates with the browser’s cryptographic random source, so every ordering is equally likely.

Paste a list above and the shuffled order appears here.

How it works

01

Fisher-Yates, not sort-by-random

The common shortcut is to sort with a comparator that returns a random result. It is measurably biased: some orderings come up far more often than others, and with certain sort implementations it can produce the same order repeatedly. Fisher-Yates walks the list once, swapping each item with a randomly chosen earlier one, and is provably uniform.

02

Every item survives

A shuffle is a permutation — nothing is added, removed or duplicated. The output always contains exactly the items you put in.

What it does

Shuffle again

A fresh order at one click, without re-pasting.

Tolerant input

Blank lines and surrounding spaces are ignored.

Runs in your browser

No account and no upload — what you type is never sent anywhere. Analytics records that the tool was opened, never what you put into it.

Practical advice

Getting a better result

  • For picking one winner rather than an order, the wheel spinner does the same draw with something to watch.
  • This is fair, not secret. It should not be used to generate anything that has to be unguessable.

Questions

Things people ask

Why not just sort randomly?

Because it is biased. A comparator returning random results violates what a sort algorithm assumes about ordering, so the outcome depends on the sort implementation and some orderings become much more likely than others.
