How do you get iPod games for free for your nano?

Actually you can get games onto an iPod Nano 3rd 4th and 5th generation as I just did yesterday with my 5th generation. A lot of people say that you can not but I just proved you can. How to is another question you go to iTunes then go under the apps section without actually clicking on it just hovering. Then click the arrow that shows up scroll down and click on ipod click wheel games. Then you can buy those games and download them onto your ipod and enjoy.
