You are shown two randomly selected episodes, and you choose the better one (or say they're equally good).
Behind the scenes, the site aggregates these selections and uses the Elo rating system to provide accurate episode rankings. It
was originally created (and modified versions are still used) for ranking chess players, and is now used
in many games today.
Each time you make a choice, the Elo rating algorithm treats it as a "match" between those two episodes. By aggregating the results for every episode and recalculating the rating after each match, it's possible to produce a data-driven rankings list that not only tells you which episodes are the best, but also how much better they are than any other given episode.
All the data was gathered from the Open Movie Database.
The Open Movie Database unfortunately doesn't always have correct information, and often doesn't have episode screenshots or is even missing some information. If you notice an error or omission, please email me at gautam[at]gautamnarula.com and I'll manually correct it!
Yup, the code for this site can be reused for any other TV show. If you have any requests, feel free to email me!
