At some point this will become a thread about Rubik's cubes, when I don't have to go to bed an hour ago. Also at some point I'm just going to start talking about my particular views on solving the Rubik's cube and other Rubik's type puzzles. There's a lot of strategy and planning involved and I'm sure someone could make some metaphors for life or some garbage like that out of it. Spoiler: My current collection Standard (3x3x3) 4x4x4 5x5x5 (somewhere, probably in a box) 7x7x7 Void Cube Helicopter Cube Rex Cube I can solve all of those, although the Helicopter gives me some trouble. I've also recently learned how to solve a Gear Cube, and can theoretically solve all of the regular face-twisting ones. I've played with up to an 11x11x11, although that thing was heavy, unwieldy, and took forever. Current opponent: A Super Square One cube owned by a colleague. Hopefully he hasn't undone the progress I made while procrastinating today. [EDIT 03/21]: Solved the Super Square One. I think I can consistently and deliberately solve it once it's in a cube shape, but not necessarily get it into that state.
