The article introduces PackIt!, a pen-and-paper game focusing on rectangle packing. It can be played competitively or solitaire, aiming to achieve a perfect packing on the grid. The analysis includes arithmetic results, complexity discussions, and reduction from 4-Restricted-3-Partition to show NP-completeness of SolitairePackIt!. The construction of gadgets and grids for the reduction is detailed. The proof involves proper turns in the game corresponding to solutions in the partition problem.
