The Rotating Cube Puzzle is a puzzle in Silent Hill 2, located in the Labyrinth. When James Sunderland turns the cube horizontally or vertically, it also turns a room with different holes (doors) in the corresponding way. This puzzle is mostly a guessing game, but it is much easier to solve if the player observes the position of the doors in the proceeding room and how they shift with the cube.
The solution to the puzzle is the upside-down face with yellow eyes. James will find an open doorway that he can pass through in the other room.
