You know that feeling you get when you finish every path and cover every square inch of a map in an RPG? When you apply that concept to the word game genre, you get QatQi. The levels in QatQi are designed with many large, open rooms, much like dungeons. There are several gold coins hidden in each of those rooms, and discovering them will result in massive score bonuses. You can view a detailed breakdown of your performance for each level you complete, including factors such as word length, effectiveness, and gold coins, among others.
