Dump Them is the third packing puzzle from Theo Geerinck and Symen Hovinga. The idea is that the box has a nuisance lid, preventing easy packing. The box has a...Show more volume of 3x3x3 and a swinging lid with two 2x3 perpendicular wings on an axis through their common side. There are four tetracubes and a tricube as pieces, so, as it fills up, there's little room left for the lid to swing.
