Description
Binary Key II is Pit Khiam Goh's two-dimensional interpretation of Bill Cutler's excellent "Binary Burr." The goal is to remove the bottom key from the frame by manipulating the internally sliding pieces. The solution requires 85 moves and is non-trivial.
Pit Khiam's description: "Binary Key II is a redesign of my Key Puzzle. The original puzzle was minimalist by design, but I felt some pieces could be changed to make them slide better. The key piece is now made shorter, and the number of rings has been increased to 5 instead of 4. The number of rings can be increased indefinitely due to the relation between the number of rings n and the number of moves Tn to solve the puzzle."
