Cube Backtracker Challenge
Cube backtracking
Here's a cube backtracking game to play around with.
The idea is that the computer will mix the cube using a certain number of moves, and you will try to undo the whole sequence. It's easy with 2-4 moves, and starts to get seriously hard at around 7. Everyone can find a level that is challenging for them.
I'm interested in hearing about problems, bugs and possible improvements.
Buttons
- Minus. Use one less move to mix.
- Plus. Use one more move to mix.
- Play. Show the solution.
- Step. Show the solution one move at the time.
- Rewind. Go back to original position. Counts as failure.
- Next. Get a new mix. Shortcuts are the '=' and space keys.
The 6 buttons can also be controlled by the 1-6 keys.
Keyboard & Mouse
You can control the cube with either the keyboard or the mouse. There's a full description here, but you can probably figure most of it out yourself by testing A, S, D, Z, X, C, the numeric keypad pad keys, Enter and shift+Enter.
