Jeremy F. Alm, Michael Gramelspacher, Theodore Rice · American Mathematical Monthly · 2013
Rubik's Slide is an electronic puzzle in the same style as other puzzles in the Rubik's family. It will be of interest to puzzle enthusiasts as well as to teachers and students of mathematics. This paper analyzes the puzzle using tools from group theory and graph theory. We discuss solution heuristics and model game-play using group theory. We briefly give results concerning solutions requiring a minimal number of moves.
