This program allows you to generate a randomly scramble cube of arbitrary dimension which can then be manipulated manually or solved by the computer. You can also input your own state using a webcam (3x3x3), or simply enter the colors of each facelet (2,3,4x.x.).
There are several built-in solving mechanisms available:
- God's Algorithm for the 2x2x2: this is the optimal solution for the given state (in half-turn metric).
- Thistlethwaite 45 (T45) for the 3x3x3: this algorithm will always find a solution of 45 moves or less, averaging at 31.
- Layer-by-Layer (Beginners') Solution: this is the method commonly used by beginners to solve the cube. More intuitive than T45, but also more extensive and less effective.
- 423T45 for the 4x4x4 (read 4 to 3, T45): this algorithm brings the cube to a state which can be handled like it was a 3x3x3 cube. When this is achieved, T45 can be applied to solve it (~180 moves on avg).
- Inverse Scramble for all cubes: it is like cheating, but when the scramble is known, each cube can be solved by inversing the sequence.
All of the above methods (with exception of the inverse scramble, which is trivial) are explained extensively in the included PDF. The PDF also contains a vast theoretical description of the cube.

how to use this?
Very nice and funny function!
Can i use it with windows 10??
Hello.Why am i getting error in running digrub.m file.plz help me.
tell me how to control hardware by this code which process can i use
Maybe add in description: Requires also Image Acquisition Toolbox for the webcam features.
Very Nice Work!
In Solve444.m I am getting an error Error using Solve444 (line 30)
Not enough input arguments.
Line 30 is x = reshape(R([2 3],[2 3],:),4,6);
What modification I need to do
Very nice! I was thinking to realize something like this by myself but then I found your code :)
excellent work,,i want contact with you >>>??
This is so helpful!!!! THANKS
Thanks very much!!! Excellent work!
how to i send the string solution to my arduino ?
It is not taking input from WEBcam ?? Please Help me out ....
Great mate, its wonderful.
you get an error when opening the "digrub.fig" file. However, if you open "digrub.m" and run it works perfectly. At least it did to me. Great Work @JorenHeit!!!
did not work, fix pls.
hello I am getting error while running digrub, error is because of rubgen function. I am using 2013a vesion. Please help me out.
Hello, I am getting errors while running digrub. I am using 2016a version
hola,pero no se como se descarga
thanks very much.really wonderful
i don't understand !!! :(
thanks for the code.i m looking for this
Super nice !
@Kuifeng It's been a long time since I worked on this project, but I can remember trying to add arrows to represent those axes... However, drawing (nice) arrows in Matlab proved not to be as straightforward as you might think, and I gave up (also because of the low priority).
Very nice work, consider adding X-Y-Z arrows in the cube?
@Krisztian You might wanna give the big blue button that says "Download Submission" a try...
How can i download it?
very nice work, thanks for sharing the code
"Download All" perhaps?
How to download??
congratulations! you are a genius! this is really nice of to share the code...thx!
Nice, Thanks for share .
done , its nice
I was searching for such a program for a long time...I knew how to solve the Cube but for a long wanted to see a program that could implement it....really nice work
