Richie's Cube is a Richie Rich Gems segment on the seventh episode of the third season of the Richie Rich animated series. It first aired 6 November 1982.
Gloria had successfully solved a Rubik's Cube, and gave Richie a chance to try it. But Dollar intervened and was anxious to try it, but assuming he didn't know what he was doing, he destroyed the cube. Gloria was disappointed, but Richie had an idea. Later that day, he fixed the cube, gave it to Gloria, but studded with jewels, gold and dollar signs, which never surprised her one bit.
