Sound Qube is a puzzle game in which the player uses sound cues to identify and eliminate Sound Qube cubes from a stack. Each stage presents the player with a three-dimensional grid of Sound Qube cubes, which is viewed from a corner that shows two sides, and which can be freely rotated to see all sides. The player controls a cursor which can pulse a sonar into a row of blocks; blue sonars can be pulsed into the left face of the stack, while red sonars can be pulsed into the right.
