This is a simple game which can be played using a ball. There are 4 holes on each side of the box , but only one hole connects the other side. Finding it is the task. This design satisfies the design challenge which is to create both a puzzle and its enclosing. The tubing inside is the puzzle and the box outside is the enclosure. This is also satisfying the parameter card which is taken to be water and Enclose. The tubing is wavy form satisfying the water condition. The whole setup is Enclosed thus satisfying the parameter card.
