There are a lot of funny free games on www.flash-game.net. Club The Penguin also a funny game in one of them. We ever play the hitting rats machine in the playground, it depends on how many rat you beat, then how many score you get. The game is trainning your reaction including your brain, eyes and body. You have to hit those colourful penguins, those are green, pink, blue, gray...etc. But do not hit the peguin which is wearing a sharp hat, it will minus your points. Just hit them, and avoid the sharp hat penguin, that’s it! Have fun!
