If you go to the website http://www.gamespot.com/iPhone/adventure-games/games.html you will get a list of adventure games made for your ipod. This is a site made to help you find the game you like and download it.

I've seen some word games of The Hunger Games but I'm pretty sure there aren't any games or apps for the iPad or iPhone, and even if there was, I'm pretty sure it wouldn't be free.
