I need help getting iPod clickwheel games on my Ipod nano and Classic!

I never owned games on Itunes for my iPod but I'm looking to add some anyway. How? I've got no idea but I'm going to ask the community if they by any chance know.

If someone want's to give a hand with this, please tell me how I'd put them on the iPod don't just give a download link and leave me to my own.
