The 2×2×2 (Pocket/Mini Cube), the standard 3×3×3 cube, the 4×4×4 (Rubik's Revenge/Master Cube), and the 5×5×5 (Professor's Cube) are the most well known, as they are all available under the official Rubik's brand. The WCA sanctions speedsolving competitions for cube orders up to 7×7×7.
It consists of a bonded transparent plastic box containing seven small cubes. There is an empty space the size of one small cube inside the box and the small cubes are moveable inside the box by tilting the box causing a cube to fall into the space. Commercial Name: Rubik's Clock Piece configuration: 3×3×2 12-position dials
A 2-layer (size 2) cube has corner cubies only. Cubes of size 2 and size 3 have single solutions, meaning that all the cube elements can have only one correct location for a solved cube. Centre cubies differ from the corner and edge cubies in that their orientation or position has multiple possibilities.
Etymologically, "cuboid" means "like a cube", in the sense of a convex solid which can be transformed into a cube (by adjusting the lengths of its edges and the angles between its adjacent faces). A cuboid is a convex polyhedron whose polyhedral graph is the same as that of a cube.
A possible placement for the three 1×1×3 blocks – the vertical block has corners touching corners of the two horizontal blocks The solution of the Conway puzzle is straightforward once one realizes, based on parity considerations, that the three 1 × 1 × 3 blocks need to be placed so that precisely one of them appears in each 5 × 5 × 1 slice of the cube.

The Cube’s earliest boost in sales came in the 1980s, when Rubik took his creation to a fair in New York—in the three years that followed, roughly 100 million Cubes were sold, creating a ...
A pyramid puzzle consists of two or more component pieces which fit together to create a pyramid. [1] [2] Two-piece pyramid puzzles cannot form a regular pyramid and can only form a 4 faced tetrahedron pyramid. The solution involves facing the square faces to each other and twisting one upright to complete the four faced tetrahedronic pyramid. [3]
The Super Square One, scrambled The Super Square One, solved The Super Square One, mid-turn. The Super Square One is a 4-layer version of the Square-1. Just like the Square-1, it can adopt non-cubic shapes as it is twisted. As of 2009, it is sold by Uwe Mèffert in his puzzle shop, Meffert's.
