In Tropical Fish Maze you have to lead a tropical fish (or a picture of your fish!) to a wurm in the maze. If you succeed, the maze will become more complex for the next level.
You can also compete against another fish and try to get to the wurm first.
Finally there is a game where a dor blocks the wurm. You have to find the key first, to get to the wurm.
There are 50 levels and any level has an unlimited amount of mazes.
