This interactive Flash version of the classic slider puzzle helps develop spatial reasoning and strategic thinking. It asks solvers to move a green square from the upper right of a grid to the lower left in as few moves as possible by shifting squares one at a time into the empty space. Students are encouraged to develop a general strategy by starting with the default 2 by 2 grid and gradually increasing the grid size. The page contains a link to a similar puzzle with scaffolding questions to guide one's thinking.
