Cerebral Challenge

Cartoon Network has a companion website and in it are some fun games that revolve around different animated characters. I particularly liked Cerebral Challenge as it tests your memory skills. Remember that frustrating memory game you played as a child? As you click onto different crates, different cartoon characters pop out and you have to remember where the "twin" or "matching character" is. It is particularly motivating because it provides all of those neat sound effects, immediate feedback, and it celebrates with a song when you finally find all of them. It also lets you know if you're lame with short-term memory skills. Heh heh...
