Rubik's Domino
Encyclopedia
Rubik's Domino is a hand-held game similar to a Rubik's Cube
. However, it is missing a layer, making it a 2×3×3 cuboid
. The 3x3 faces can be turned 90-degrees as normal, but the 2x3 faces can only be turned 180 degrees. Other cuboids of 2x2xn (if n is an even number) will solve like multiple Dominoes at once. The original version had white and black plastic layers. Each 3x3 face displayed a number of dots from 1-9. More recent versions use the traditional six-colour scheme, as seen on most other twisty puzzles. It has 406,425,600 potential positions and any position can be made into a solved position in 19 moves. It was registered as US Patent number 4,378,116 on 29 March 1983 by Ernö Rubik.
