Play the game at http://snarxiv.org/vs-arxiv/.

 

The concept of the game: You are presented with the titles of two papers. One paper is a real one posted at the arXiv. The other is fake, with the title automatically generated using a context-free grammar. Your job: Guess which is the real paper. After guessing you will be presented with another pair of titles. You can play as long as you want. The game will give you a ranking based on your ability to ferret out the real physics papers versus the fake ones. Do slightly worse than 50% and you are ranked "worse than a monkey". Dropping down even lower makes you a "ninth year graduate student". Do well and you will rise from "better than a monkey" to the rank of "undergraduate" and may eventually achieve the rank of "Nobel prize winner".

63% after 30 guesses

Haha, I got 60% out of 30. I'm better than better than a monkey.
