Expert Plumber Puzzle is a free iPhone game developed by AppForge Inc. It is a challenging puzzle game that requires the player to fix a pipeline to make the water reach a little flower in the hottest desert where water is scarce. With 100 free levels, the game is easy to play but hard to master.

The game is simple to understand, and the player only needs to turn different pipe pieces by touching them and connect all of them to make a complete pipe. However, the catch is that the player has a limited number of moves to save the flower before running out of moves. Although there is no time limit, the player has to think strategically before each move.
