Rubik

Rubik is a surname of Hungarian origin. It may refer to people bearing the name, most notably Ernő Rubik (born 1944), a Hungarian architect and professor who invented the Rubik's Cube in 1974.

The Rubik's Cube is a 3D combination puzzle consisting of six colored faces, each made up of a 3x3 grid of stickers, connected by a rotating mechanism. The objective is to restore the cube to a solved state where each face shows a single uniform color. After its international release in 1980, the puzzle quickly became a cultural phenomenon and a staple in mathematics, education, and recreational puzzles.

The cube has had a lasting impact beyond its original form, giving rise to a large community of enthusiasts, competitive speedcubing, and numerous variations and spin-offs. It is widely regarded as one of the best-selling puzzles and toys of all time, and it continues to appear in popular culture, puzzles, and educational contexts around the world.
