The 2x2 Cube, or Pocket Cube, is a simplified version of the Rubik’s Cube with just 2 pieces per face, making it easier to solve and ideal for beginners to grasp basic cube-solving concepts. The 3x3 Cube is the classic Rubik’s Cube with a 3x3 grid per face. It has medium difficulty and is fundamental for learning more advanced solving techniques.

The 6x6 Cube adds complexity with more pieces, requiring advanced strategies for edge pairing and parity handling. The 7x7 Cube further intensifies the challenge with even more pieces and multiple parity errors, demanding highly advanced solving techniques.

The 4x4 Cube (Rubik’s Revenge) adds complexity with extra pieces, requiring edge pairing and handling parity errors, making it more challenging than the 3x3 Cube. The 5x5 Cube (Professor’s Cube) increases difficulty further with even more pieces and complex parity issues, demanding advanced techniques and algorithms.

The Skewb features a unique turning mechanism where corners twist around a central axis, offering a distinct challenge compared to standard cubes. Solving the Skewb requires specialized methods and algorithms tailored to its unconventional movement. The Pyraminx, a pyramid-shaped puzzle, introduces its own set of mechanics and solving techniques. Its difficulty ranges from intermediate to advanced, depending on the solving method used, and provides a different experience from traditional cubic puzzles.
