Kubs
Kubs are a type of puzzle, most commonly known as a Rubik's Cube, that involves manipulating a series of interlocking pieces to achieve a specific goal, usually a solid color on each face. The original and most famous example is the 3x3x3 Rubik's Cube, invented by Ernő Rubik in 1974. The cube consists of six faces, each a different color, and is divided into smaller cubies that can be rotated independently. The challenge lies in returning the scrambled cube to its original solved state.
Beyond the standard 3x3x3, a variety of other cuboid puzzles exist, often referred to as "cubes" collectively.
