Rubiks

Rubiks is a term that often appears as a misspelling or nonstandard rendering related to the Rubik family name and its famous puzzle. The standard name associated with the most widely known object is Rubik's Cube, a 3D combination puzzle invented by Ernő Rubik in 1974. The puzzle was originally called the Magic Cube and was marketed internationally starting in 1980.

A standard Rubik's Cube has six faces, each composed of nine stickers of a single color; through rotations of the cube's sections, the goal is to arrange the colors so that each face shows a uniform color.

Rubik's Cube became a global phenomenon, contributing to the rise of speedcubing, with competitions organized by the World Cube Association and an ongoing ecosystem of tutorials, variants, and mass-market versions.

Beyond the 3x3 model, there are multiple variants (2x2, 4x4, 5x5, etc.), as well as electronic and virtual versions.

In general usage, Rubiks without an apostrophe is considered incorrect for the cube and for the surname Rubik when used possessively; proper forms are Rubik's for the cube and Rubik as a surname. The term Rubiks may appear in informal writing or as a misspelling.
