A great puzzle game that can really keep you stumped.
But of course it is not that simple. First of all, you don't get to choose what order they give you the pipes in. You get a random assignment and you work with what you get. Planning ahead is a must once your out of the entry levels.
And to make things a bit harder, you have to have a minimum number of pipes used before you reach the goal.This can become a real challenge in the later levels.
Overall a great puzzle game that should be in every puzzle fans collection.
