The Rubik's Triamid is a mechanical puzzle invented by Ernő Rubik and released in 1990 by Matchbox.[1] The puzzle was patented in Hungary in 1991.[2] It was re-released in 2017 at the American International Toy Fair[3] by Winning Moves.
The puzzle is similar to the Rubik's Cube in that the objective is to manipulate the puzzle until all sides are uniform in colour. The puzzle itself forms a triangular pyramid, so that there are four sides and colours.
