Hey-oh!
This is the second product from MySociety that I've hunted, and interestingly, this game uses the other product, an API called Every Politician, for it's data. It's really fun to play (I was the top of the leaderboards for two months once, but sadly I've fallen off) and it's an easy way to contribute to MySociety's data about the world's politicians.
