Theoretically, a normal Rubik's cube can appear on the WPCs, since it is playable regardless of language or culture. However, it doesn't, because in order to solve a Rubik's cube, a bunch of specific knowledge is normally required. Nonetheless, some puzzles based on Rubik's cubes has appeared on the WPCs.
- Given the sequence of moves, identify the final state of the cube. (from WPC 2017)
- Given the patterns of three visible sides of the cube, identify symbols present in the middle of three invisible sides. (from WPC 1999)
History of the puzzle
Rubik's Cube is named after Ernő Rubik (Hungary) who invented it in 1974. It became a worldwide craze in the 1980s.
There are many variants of Rubik's cube, including Megaminx and Pyraminx (both invented by Uwe Mèffert (Germany)). They are often collectively called twisty puzzles.
