Sliding

Solved

Simplicity is the brilliant design of sliding-piece guru Jimmy Stephens from Atlanta. Using a computer search and a genetic algorithm, he discovered the hardest sliding piece puzzle there is on a 4x4 grid. Even though the puzzle has only four pieces, many people have tried and failed to solve this seemingly simple puzzle.

You can play an on-line version of this puzzle at Jimmy's website, but if you want to baffle your friends, nothing beats an original 3D-printed Shapeways sample.

Watch the YouTube video.

Please contact Oskar directly if you are interested in obtaining a fully colored sample of this puzzle.
