Try to solve the rolling cubes puzzle!
You start with eight cubes around a center hole. Each cube is black on
the top and white on the bottom. The object is to roll the cubes around
until the cubes are in the start position but with the white faces on top.
Click on a cube to roll it.
It is possible to win in 36 moves. Good luck! Solving the puzzle
is harder than it looks. The solution is
here if you need it.
