WEBSolving the 15-Puzzle. Chris Calabro. June 14, 2005. Abstract. The n n puzzle game is played on a matrix of numbered tiles with. 1 tile missing to allow tiles to shift. The goal is to order the tiles by a sequence of shifts. We provide a O(n2)-time algorithm to decide when an initial con gu-ration of the n n puzzle game is solvable.
