I built a website to answer the question: what is the best LEGO minifigure?

It works by showing users two randomly selected LEGO minifigures and asking them to pick their favourite. This process is repeated over and over, and an Elo rating algorithm (the same approach used for chess rankings) turns user choices into a rating for every minifigure, producing a full ranking from best to worst.

So far, over 1.3 million votes have been processed. The Elo approach means a minifigure doesn't need to be compared against every other one directly, as its rating is based on which ones it beats and loses to over many matchups.
