After reading up here I realized that the writing must line up (which it now does) because of the need for each piece to be in the correct place. When I was working one side at a time all the letters were misplaced, which would have made solving impossilbe.

IIRC, it is impossible for the centre pieces to be positioned wrongly. by design, centre pieces of course do not move (shift place) at all since they are the pivots, but they can be rotated around, and if there is writing across them, the alignment could be incorrect in relation to the other 8 pieces on that face.

I also recall from the book released by the teen whiz-kid that there was a sequence that could rotate the centre piece only and disturb nothing else, but since I never had any cubes other than plain coloured ones, I never needed to learn how to do that.

[edit: it didn't make sense... :b ]

It only seems that way.
Each and every cubicle of the big cube is unique. It can only go to one place for the solved position. So, if you solve the puzzle, the writing will be there automatically - always the same, the way they put it.
True except for the center square, which can rotate. It was possible to solve the cube for the colors but still have the writing on the center square out of alignment (rotated) relative to the writing on the surrounding squares. I devised moves to rotate the center square without altering the positions of the other pieces.

I always went for the "take it apart - put it back together" method.

Absolutely true. I forgot about the central pieces, because "normally" they play no role. Yes, it complicates things a bit!

too funny. we just picked up a cube for my gfriend's son!

i was one of two kids in my school that could solve that damn thing. it was kinda cool but irritating at the same time. people i didn't know would stop me and ask me to solve it...teacher's were asking me to solve the ones they took away from kids during class...it was ridiculous. it also didn't help that the other guy who could solve it was also asian and that (at the time) we both hated each other's guts. people would get us confused and we were always competing with eachother. (we later became really good friends...go figure.)

i even took mine apart and lubricated the insides with vaseline so it would move quicker! i don't remember my speed record, but i'd guess it was under a minute.

anyway, now i can do the first two layers easy. doing the bottom corners is okay, but i'm totally stuck on getting the last two middle tiles in the bottom layer in place. help!
