Grow Cube

Is the first computer game that requires you to have a pencil and paper handy - you'll need it I promise. The devious devisers of the game say that, "all you have to do (understatement) is to add the right element at the right time other otherwise your cube isn't going to grow." You'll get the hang of it all soon enough depending upon how clever you are of course! My tip: Start with the man, and make lots of notes.
