Question 1

How does the Fisher-Yates shuffle work?

Accepted Answer

Starting from the last element, swap it with a randomly chosen element from the remaining unshuffled portion. Repeat until all elements have been processed. This guarantees each permutation is equally likely.

Question 2

Can I use this to pick a random winner?

Accepted Answer

Yes — paste your list of names, shuffle, and the first item is your winner. Or shuffle multiple times and take the top N items for multiple winners.

Question 3

Is the randomization truly random?

Accepted Answer

This tool uses the browser's Math.random() which is a pseudo-random number generator. It is sufficient for games, raffles, and decision-making but not for cryptographic purposes.
