1. Pick a random nonfiction book off your shelf (fiction could an easier version of the game; I'm not sure).
2. Flip to a random page.
3. Choose a word/term from the page that is (a) a proper noun (b) a period-specific term or (c) a disicipline-specific term.
4. Look up said word/phrase/term on Wikipedia.
Five points if you get a stub.
Ten points if the article doesn't exist.
Fifteen points if the article doesn't exist and you create it.
You get ten things to look up.
I have no idea how hard this game is but some test entries suggest it'll be pretty difficult.
