Rubik's Cube Solved

Late this summer, my family and I took a trip to Duluth, MN for a get-away weekend.  After a great weekend of hanging out on Lake Superior, eating pie, and touring ore ships, we stopped at a toy store for souvenirs.  Instead of getting a Duluth lift-bridge snow globe or a Split Rock light house t-shirt, my 8 year old son fell in love with a Mini-Rubik’s Cube.  My wife gladly bought it for him, thinking that it would keep him busy in the car during the 4 hour ride back home.

Scrambling the cube and trying to solve it kept him busy for about an hour, but like all of his Transformer toys, he soon started asking me to figure it out for him.  I laughed at him and said, “No way!  I had one of those 20 years ago, and had to break it apart to solve it!”  He soon forgot about the cube, and we played I Spy for the rest of the trip home.

When we arrived home, my son placed the cube on a shelf and didn’t touch it again.  About a week later, I noticed it again and got curious to see if it was still as hard to solve as it was 20 years earlier.  I picked it up and spent about 20 minutes twisting and turning the cube until I got frustrated and checked google to see if there was some trick to solving it.

It turns out that there are several different systems for solving them.  Some of them are very technical and hard to understand, but I found one that was pretty easy to follow.  You make a series of maneuvers, called algorithms on the cube.   Each one is used to solve a different part of the cube.  I spent about a month memorizing them and can now solve any standard 3×3 cube in less than 5 minutes.  5 minutes is pretty good, but the world record is around 6.5 seconds!
