This new toy from the inventor of the Rubiks cube certainly is different. And challenging. Not nearly as hard as the cube itself, but still makes you want to try and work it out.
Obviously Mr Rubik is a very bright person able to invent such amazingly difficult puzzles. And therein lays the success of his products. They look simple enough to try to complete, but the element of discovery and joy comes with trying to solve them.
Another winner indeed. Good on you Erno Rubik!!
