Solving a Rubik's cube in less than 60 seconds
A couple of months ago I bought a Rubik’s cube in a nearby shop and after reading some guides on the net I learned how to solve it. A few hours later I could solve it in about 4 minutes all by myself. After a few days of practice I was down to about 2 minutes, but it was difficult to see how I could improve much further using the beginners method I started out with. My cube and dexterity does not allow me to do more than about 2 moves per second so I realized that I had to reduce the number of moves, rather than speeding up my fingers. After reading several websites about speedsolving techniques I set my self a tough goal - to become a sub-60 cuber. I was determined to study and practice the art of solving the cube until I could solve a Rubik’s cube in less than 60 seconds on average.
I can now often solve it in less than 60 seconds, but I am not stable enough to call myself a sub-60 cuber yet, but I am very close. Give me a few more weeks (or months) and I will get there. While playing with the cube on the bus, at work, at home, in the pub, basically everywhere, all the time, I sometimes meet other geeks that want to learn how to solve the cube fast as well. So I thought I should write up a guide about how to get started.
If you do not know how to solve the cube you need to study one of a billion guides that are available on the net. Here is a beginner solution by Leyan Lo that I recommend. Once you can solve the cube without referring to a guide, you can start to read more advanced stuff. The ultimate guide is written by Jessica Fridrich, but it is not easy to read. I found CubeFreak by Shotaro Makisumi to be the most useful site out there.
After studying these sites, as well as hundreds of other sites and watching plenty of youtube videos, I have ended up with a simplified Fridrich method with a four-look last layer. Here is what I do to solve it in less than 60 seconds:
- Solve the extended cross ~5 sec (always a white cross)
- Solve the first two layers (F2L) ~30 sec (keep cross on bottom)
- Orient the last layer edges ~5 sec (1 out of 3 algorithms)
- Orient the last layer corners ~5 sec (1 out of 7 algorithms)
- Permute the last layer corners ~5 sec (1 out of 2 algorithms)
- Permute the last layer edges ~5 sec (1 out of 4 algorithms)
My current focus is to improve the F2L step as I am still struggling to get under 30 seconds, but I am confident that with some more practice I will manage to get closer to 20 seconds and then I can label myself a sub-60 cuber.
For further inspiration, here is a video of a sub-120 cuber and a sub-10 cuber.
