 The hailstone pattern is a cool number pattern that for any positive whole number, it will always end in one. It repeats the following steps until it gets to one: if the number is even, it will divide by two. If the number is odd, it will multiply by three and add one.

 Snake is a game where you control an always moving character using the keys. The goal is to hit the target without hitting a wall. If you get the target, your character starts moving faster and the target appears somewhere else. The game ends when you hit the wall. 
 
 Here is an example of the game created in Scratch: http://scratch.mit.edu/projects/2627038/

 If you want to make more complex games, there are some additional concepts that you can put to use. The first is using functions (which you have created before) to change variables.

-###Adding Complexity - Classes and Sprites in Pygame
+### Adding Complexity - Classes and Sprites in Pygame
 
 For the 6 day track we didn't cover using sprites in Pygame because it involves a new concept: classes. A class can be thought of as a blue-print that you can use to create many copies of something. Each copy can have their own set of variables (called properties). In pong there were already a lot of variables to keep track of, what if the game had many more objects in it!
 
 Take a look at [catch the good ones.py](Finished/catch the good ones.py) for an example of a simple game that uses a class. In this game your goal is to catch all the falling green balls and avoid the red ones. (You must also download the red_ball.png and green_ball.png files in the [Finished](Finished/) folder.)
 
 There are many sources to learn more about Pygame sprites and creating Python classes. If you are learning on your own, check out a book like [Hello World! Computer Programming for Kids and Other Beginners](http://www.amazon.com/Hello-World-Computer-Programming-Beginners/dp/1933988495).
