It's one of these concepts that keeps poping up independently at many places (there used to be edit wars at Wikipedia pages about manual versions of this game with many people claiming they invented it :).
Okay the implementation of this is really well done. It had everything I was expecting an automated version of this game would have.
My one complaint is that the frame for the game seemed quite slow compared to normal scrolling on Wikipedia (Just checked and yes there is a noticeable lag in scrolling in Chrome on Windows). This is some what frustrating in a game designed for speed!
One other piece of feedback -- maybe hide click paths in the left hand nav until the user has marked some sort of "given up" button for current race?
It would be nice to see the active players list on the home page too (I would have started a lot faster and with less hesitation had I known X amount of people were playing just then).
I've always thought it would be fun to play a "black hat" wikipedia game. You would register an account, and then proceed to make false edits throughout the site.
To get scores, we'd take all of the edits for each account and multiply the brazenness/funniness of the edit by the number of pageviews you got before the edit was reversed.
We used to play this game at school. We just did it ourselves though (without a website). I think your page is a bit confusing, and it doesn't leave me with any idea of where to start.
I'd simplify the page, and make it obvious! Good luck.
Excellent idea, really love the fact you've made a game out of what everyone experiences on wikipedia already. One issue, scrolling the article on the iPad doesn't work. Other than that, awesome.
(Why, no, that isn't a directed graph of wikipedia articles and a BFS implementation behind my back.)
