Even if you haven't heard of Facebook's new game "Snake" before, you've probably played it at one point or another on your cell phone or computer.
The idea is that a snake - at first one dot, then many in a slithering string - swirls around your screen, trying to eat the red apple. You guide it towards the apple, and the game gets harder by going faster and making your snake longer.
Facebook has its own version of Snake. Check out this tutorial to learn how to score a high 1180 in the game.
