What we do
Who Played Both is based on a simple game football fans have played among themselves for years: two clubs are named and you look for a footballer who has played for both teams. We have moved that game onto a screen that keeps time, checks the answer and keeps the score. Our aim is to take the argument out of "he did play there, no he didn't" and turn it into a pure contest of memory and speed.
Each round lasts about half a minute. For a short break you can play a single match against the bot, or challenge a friend with a room code. We explain the rules in detail on the How to Play page.
Where does the data come from?
Which footballer played for which club is compiled from open sources. The backbone of the historical careers is Wikidata (CC0), which anyone can use freely. Squads for the current season are taken from Wikipedia club articles.
These sources are maintained by volunteers and are sometimes incomplete or wrong. For example, years spent in a youth academy may be attached to the main club, or summer transfers may not have been entered yet. For this reason we accept doubtful records as answers, but we do not use them when creating questions in the game. If you spot a wrong record, write to us.
