Fling Theory is a brilliantly inventive title, put together with great attention to detail, with a core game concept that's both addictive and fun. The game is free to download and comes with 23 levels, but there are in-game purchases for turning off ads ($0.79) and unlocking extra levels ($0.79). Currently there's a special, limited time, offer combing both of these extras for $0.79.
