Corner Table – End Table

International Puzzle Party (IPP) Exchange Puzzles come in all sorts of different shapes and sizes (and colors and materials and textures and …).  Although End Table is larger than you would expect and smaller than the name would imply, the name refers to the shape/location of the red square piece in the tray and not its size.

End Table wa designed by Goh Pit Khiam and was Khuong An Nguyen’s IPP41 exchange puzzle.  It’s 3D printed with a marble PLA tray and 6 translucent PLA pieces.  I didn’t want to risk breaking the puzzle by undoing the clips that hold the top in place but it looks like a nice mechanism.  They clips appear to be hinged on the top but I don’t believe in unnecessary violence to puzzles (except for the ones that I make – in fact abusing them is a necessary part of the design/manufacturing process and therapeutic to boot).  The translucent PLA used for the pieces allows you to see the infill pattern.  

It’s immediately obvious that this is a multi-color, apparent-rectangle, restricted-opening, 2D tray-packing puzzle.  The 5x4 tray has a 2 voxel opening in the side.  The objective is to place all the pieces in the tray through the opening with the red piece in the upper left corner (assuming that the opening is in the bottom left corner).  Never fear, there is a red square printed in the tray where the red square piece needs to go.  The pieces consist of 2 blue Is, 2 green Vs, 1 purple N, and 1 red O.

Windows for manipulating the pieces are very large.  The size of the puzzle is much larger than you would expect for this type of puzzle.  It makes handling the pieces easy.  I also found solving the puzzle to be easy as well although sometimes you just get lucky.  Placement of the pieces seemed logical with the red square restricted to the designated corner.

Just for fun, I tried packing the pieces with the red square in the other 3 corners without issue.  None were difficult.  However, after looking at the solutions that I came up with for the other 3 corners, I decided that maybe I did get lucky on the official objective since that solution had a property that the other 3 didn’t.
