Domande frequenti
What happens if the lists are different lengths?
A is matched against a shuffled B. If B is shorter than A, B repeats as needed so every item in A gets a match.
Can I match a list to itself?
Yes. Paste the same list into both A and B to create random pairings within a single group.
How random is the pairing?
List B is shuffled with the Web Crypto API, giving every possible pairing an equal, unbiased chance.
Do my lists leave my device?
No. The matching runs entirely in your browser, so neither list is ever sent to a server, and it works offline.

Splitting 17 items between 4 people means somebody gets a fifth one. Here is how a fair division tool deals items out at random, why it splits by count rather than value, and the one thing you should do to your list of people first.
- Who gets which prize? Let chance decide — and show your work
Picking winners is the easy half of a prize draw. The fight starts when someone has to decide who gets the good prize and who gets the mug. A random prize assigner matches people to prizes in one shuffle nobody chose.
- Secret Santa beyond December: swap formats for the whole year, and a draw you can re-run
The Secret Santa mechanic — everyone gives to exactly one person, nobody draws themselves — works just as well for book swaps, snack exchanges, and kindness weeks as it does in December. Here's a year of formats, plus how a seeded draw lets you reproduce the exact same assignment on demand.
- A chore roster that actually feels fair (and stops the arguments)
The same person always ends up on bathroom duty. Here's how a random chore roster — fresh shuffle each day, rotated across the week — spreads the jobs nobody wants without anyone keeping score, and how it handles having more chores than people.
- Matching two lists fairly: zip prizes, tasks, and partners at random
Assigning a list of people to a list of prizes, chores, or projects sounds trivial until you do it by hand and someone notices a pattern. Here's how a two-list matcher zips one list to a shuffled copy of another, what happens when the lists are different lengths, and when to reach for a different tool.
