The Bind puzzle is a very tricky and challenging mechanical puzzle, first try to unlock the puzzle, you will have to find the right place to hold the cube in order to release the 4 pieces. If you do it the right way the pieces will move easily and smoothly and you will be able to take all the pieces apart. Putting all 4 pieces back into a cube will be much challenging!
