The classic colored-cubes puzzle from the 1960's is back to tease your brain! Take a good look before you begin. Once you open the package and mix them up, these four cubes may never be seen in the correct order again. To solve the puzzle, arrange them in a row so that all four colors appear on each of the four sides. Sounds simple doesn't it? So what are you waiting for. Give it a try! (Not so easy, is it?) Popular in the 1960's, this game is back to challenge you.
