The Overlapping Shape Brainteaser. Line up for this vexingly visual brainteaser! Arrange four transparent shapes to perfectly form one of 60 unique geometric patterns. The challenge is that all four shapes are identical, so you will have to figure out how they overlap to precisely outline each pattern. Try it solo or race against another player in a "first to the finish line" competition.
