ABSTRACT
A recent popular puzzle is Instant Insanity by Parker Brothers. This puzzle consists of four cubes. Each face of a cube is colored with one of four colors: red, white, blue, or green. The objective is to stack the four cubes in such a way that each side of the stack contains each of the four colors. The order of the colors on each side of the stack is immaterial. The cubes for this puzzle are constructed with plastic faces that have been cemented together. Each cube will retain the same number of red, white, blue, and green faces as the original cube.
