Dino Cube
| ||||||||||||||||||||||
The Dino Cube is a three-layered twisty puzzle in which three edge pieces at the corners are moved at a time.
History
The first functional Dino Cube was invented in 1985 by Robert Webb of Australia, made out of paper. Stephen Harvey also produced a prototype independent of Webb in 1990. However, the Dino Cube was not mass produced until 1995 by S.Y. Liou, convinced by Liang-Yen Wu. The first mass-produced Dino Cube included 2-color, 4-color, and 6-color options to choose from.
In 1998, James R. Holloway applied for a patent for the Dino Cube and was granted the patent in 2000, filed as patent US6056290.
