Griffiths) To: cube-lovers at MIT-MC Subject: Re: Ultimate Cube Message-id: <[MIT-DMS].217732> I have seen the 'Ultimate Cube', except here in Boulder, it is done a little differently. They are all Black cubes, and come in the standard (Ideal standard) container. And (no offense from me, this is what they are called) they are labeled 'Polish Cubes' with 'No wrong move'. Also, we have a Pyraminx puzzle (which is rather trivial compared to the cube) and it has a problem: if you twist the top cube on a certainm side too many times, (like 3 twists) it comes off and the whole mechanism falls apart. Has anyone else had this problem? How can I correct it? -Rob.
