Can you take it apart? Can you assemble it again?
Rattle puzzle has four of the same shape pieces that are loosely interlocked together to make up the puzzle. Because the pieces fit loosely it would seem that it would be easy to take apart. However, one is soon at a loss, as the puzzle gives little hint of how it might be solved. This is an interlocking style puzzle where pieces need to be moved slightly, shifted left or right, then another piece moved slightly and shifted in a series of numerous moves.
