Oskar's Cube, the original 5x5x5 version was designed 11 November 1984. The concept was published in Scientific American in 1988. A plastic version was brought to market in 1992 by an Australian company. A few years later, Bits and Pieces produced a metal version. The present 3.5x3.5x3.5 version was designed in around 1994, and first prototyped in wood by Jerry McFarland. The object of the puzzle is to move the cross through the three maze from the square to the dot.
