Description

This 25 piece puzzle utilizes 4 pin mazes on the key piece along with four moving pin pieces to create a 4 bit binary numerical sequence (not gray code). Other Binary puzzles use Gray Code where only one piece moves at a time for each step, with Binary sometimes multiple pieces need to move for a step. 45 moves to remove the key piece. It was entered into the IPP35 Design Competition. Only 7 were made. A neat design but due to too many time consuming machine setups these will not be made again.
