How does the list randomizer work?
This tool uses the Fisher-Yates (Knuth) shuffle algorithm — the gold standard for generating unbiased random permutations. Each element is swapped with a randomly chosen element from the remaining unshuffled portion, using crypto.getRandomValues() for cryptographic randomness. Every possible ordering has exactly equal probability.
Common uses
- Randomize presentation order — shuffle student names, playlist items, or task lists.
- Fair ordering — determine random turn order for games or competitions.
- A/B testing — randomize items for survey or experiment ordering.
- Playlists — shuffle song lists or reading lists for variety.
