I had a Rubik's Cube back in the early 80's and I vividly remember reading a solution book which was easy to memorize. When my cube resurfaced recently, I couldn't come up with the name of that book, so I randomly picked this one. I found the nomenclature, diagrams, and descriptions of the moves awkward and difficult to understand, and although I was eventually able to solve my original cube (3x3) and the 5x5 Professor Cube, it took a LOT of false starts (and diligently staring at the book for several hours). I still haven't re-memorized the 3x3 solution moves, which I was able to do fairly quickly with the original book. Unfortunately, I don't remember how the original solution book showed the moves, except that reading and memorizing the moves was much more intuitive with the old book than with this one.
