We'll show you an image from an O'Reilly book along with four possible book titles. All you need to do is select the correct one. Simple, right?

Each question is worth 10 points initially, but decreases in value as time progresses. If you choose the correct title, the current value of the question is added to your score. However, if you answer incorrectly, the current value of the question is deducted form your score. If you find you're completely stumped, you can always hit the "Skip This One" button and move on to the next question. There is no penalty for skipping questions.

After answering a question correctly, you may earn a bonus point by giving us a tag describing the contents of the image.

A game consists of 50 questions. To start a game, you must first sign in. Once you've signed in, you may start as many games as you like. If you leave a game before it is finished, you can pick up where you left off by way of the "Your Games" tab on this page.

After you've completed (answered or skipped) all 50 questions, we'll give you a summary of how well you did.
