The Pocket Cube is a smaller version of the traditional Rubik's Cube, featuring a 2x2x2 grid instead of the standard 3x3x3. It consists of eight corner pieces that can be rotated, making it a simpler puzzle for beginners. The goal is to twist and turn the cube until each of the six faces displays a single solid color. Despite its compact size, the Pocket Cube offers a fun challenge and can be solved using various methods, including intuitive approaches and algorithms. It is popular among both casual players and competitive speedcubers, who enjoy solving it quickly and efficiently.
