Mechanical puzzles | Combination puzzles
The Rubik's Triamid is a mechanical puzzle invented by Ernő Rubik and released in 1991 by Matchbox. 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. (Wikipedia).
