The boondoggle! The cube, having 2,392 possible solutions, has caught the attention of many. I always tell people to try the lower levels first to get a feeling of the puzzle and perhaps later solve the higher shapes. But everybody wants to get the cube or the checkerboard solved first!

In the sample solution I have the 1x3x4 within the puzzle. The real challenge here is to find a solution that is totally interlocking and with no sub shapes.

Can you do it? Can you get the pieces together?
