I got a 5x5 cube recently, and learned how to do it by only learning a few algorithms.
In order for you to be able to finish the cube, you will need to be able to solve a 3x3 cube, but being able to solve a 4x4 cube would also enhance your abilities for it, since the algorithms can be used on both.
If anything is unclear, just ask and I can clarify it for you
1. This is a LONG INSTRUCTABLE. It will take time and effort to get through this cube, and you need to have some free time to solve your cube.
2. I am Canadian, so deal with the u in colour.
3. I am assuming you have a 5x5 cube. If you do not, they cost up to $40 CAD, so be prepared to spend a little bit of money on it.
Step 1: My Collection/experience
I started cubing over the summer of 2007. I got a dollar store "magic" cube, which was a cheap Rubik's cube. It came with instructions, which I memorized, and have now fine tuned so I can solve my cube with a 12 cube average of 51 seconds.
I can solve all the puzzles you see here, no instructions.
I found out how to do this by watching a long youtube video tutorial about how to solve this, and read some text instructions. I have 2 5x5 cubes, a few 3x3 cubes, and the 4x4 cube.
