The Low-Memory Rubik’s Cube Solution
Are you one of those people who has a Rubik’s Cube sitting on a shelf or in a drawer somewhere, and you’ve had it since the 80s but you’ve never solved it? Are you the type of person who uses more than one conjunction in the same sentence? Great! Then we have one thing in common! No, but seriously, folks.
So I wrote a sort of beginner’s guide to solving the Cube. And I call it the Low-Memory Method, because you only have to memorize 8 (eight) algorithms. There are probably several hundred algorithms one could possibly learn to solve the Cube, but my theory is that the fewer you need to actually solve it, the more people will get interested in picking up their old Cube and giving it a shot. And the trick is that if there’s an alg for rotating three pieces clockwise, then two things are true:
- There’s also an alg for rotating those pieces anti-clockwise, and
- You can perform the clockwise alg twice and it will achieve the same end result.
Anyway, I have a few that I needed a little help with. Megaminx? Seriously? That thing’s got twelve sides. With ten pieces on each side. I was able to solve eight sides on it with no help. But the last four started to get crazy. After several days of pulling out my hair and almost Throwing It Out The Window, I finally sought help. And got it. Well, some of my puzzles weren’t so easy to find help on.
