This is the third of the Leftovers design by Laszlo. It uses different pieces and different moves than the other two and is a solid addition to the collection of any interlocking puzzle fans. Of course non-linear moves are required, and finding the proper orientation and order of assembly is a fun process. Not devastatingly difficult, but then again not all great designs are!
Construction of this puzzle is very good, with strong side glued joints and solid wood components.
