RUBIK'S EDGE 3X3X1
It's one layer of a standard 3x3x3 Rubik's Cube and it's trickier than it looks. Mix it up and try to get the colours realigned so that each side has only one colour. The slim profile makes it a great "go anywhere" puzzle. Fiddle with it and try to form these shapes and many more.
