The World Cube Association governs competitions for mechanical puzzles that are operated by twisting groups of pieces, commonly known as 'twisty puzzles'. The best known of these puzzles is the Rubik's cube.

The Rubik's Cube is a classic 3D combination puzzle invented in 1974 by Hungarian professor Erno Rubik. It features six coloured faces with nine squares on each. With over 43 quintillion possible combinations, the goal is to twist and turn the cube so that each face returns to a single solid colour.

There are two biographies about Erno Rubik:
