rufascube
Unique 3D slider puzzle that looks like a rubics cube.
This is NOT another Rubic's Cube. It's a much simpler slider puzzle that is incrementally solvable. A 3x3x3 arrangement of cubelets with the center one missing allows sliding permutations. After a randomization, the goal is to restore the cube to its original configuration based on color and alphabetic hints. Written in Ada and compiles on Windows, OS-X or GNU/Linux.
