Boxy by László Molnár is a unique packing puzzle concept. You must pack the five simple pieces into a clever box with a rotating and connected top/bottom panel. Joined by a dowel, the top and bottom move together and therefore limit access to the interior. As the box fills with pieces, the movement of the lid is increasingly restricted. Despite multiple possible configurations, you can assemble only one in a particular order. Boxy is a fun, challenging puzzle. I'm thrilled with how this puzz...

Item is in brand new condition.Pack four pieces into box so that when lid is inserted all pieces are positioned below lid surface (not protruding out of hole in lid). A seemingly simple puzzle but very unorthodox solution for an unrestricted packing puzzle.

Item is in brand new condition and in original packaging.Description from Cubicdissection Website by Eric Fuller:Obstacle Box is the first design I have made by the talented Lucie Pauwels. A very interesting design, it combines a simple packing puzzle with a very unconventional box.

With many assemblies outside the box but only one inside the box, this is a fun solve for sure!...
