The Rubik's Revolution is a handheld electronic game invented, designed, developed and patented by Rehco, LLC, a Chicago toy and game inventing firm. The Rubik's Revolution was formerly distributed by Techno Source and received the 2008 TOTY Game of the Year Award. Designed to resemble the classic Rubik's Cube puzzle, the device is a single rigid cube; it is about as large as a Professor's Cube, with each face subdivided into 9 square sub-faces. The center square of each face features a recessed LED-lit button colored to correspond with the stickers on the remaining squares. Gameplay involves pressing the buttons when they light up, or when directed to by the game's recorded voice.
