The Rubik's Cube is a 3-D combination puzzle originally invented in 1974 by Hungarian sculptor and professor of architecture Ernő Rubik. Originally called the Magic Cube, the puzzle was licensed by Rubik to be sold by Pentangle Puzzles in the UK in 1978, and then by Ideal Toy Corp in 1980 via businessman Tibor Laczi and Seven Towns founder Tom Kremer. The cube was released internationally in 1980 and became one of the most recognized icons in popular culture. It won the 1980 German Game of the Year special award for Best Puzzle. As of 14 March 2021, over 450 million cubes had been sold worldwide, making it the world's bestselling puzzle game and bestselling toy. The Rubik's Cube was inducted into the US National Toy Hall of Fame in 2014.
Ernő Rubik is a Hungarian inventor, architect, and professor of architecture. He is best known for the invention of mechanical puzzles including the Rubik's Cube (1974), Rubik's Magic, Rubik's Magic: Master Edition, and Rubik's Snake.

Speedcubing is a competitive sport involving solving a variety of combination puzzles, the most famous being the 3x3x3 puzzle or Rubik's Cube, as quickly as possible. A person who practices solving twisty puzzles competitively is known as a speedcuber, or a cuber. For most puzzles, solving involves performing a series of moves, known as algorithms, that alters a scrambled puzzle into a solved state, in which every face of the puzzle is a single, solid color.
The Pyraminx is a regular tetrahedron puzzle in the style of Rubik's Cube. It was made and patented by Uwe Mèffert after the original 3 layered Rubik's Cube by Ernő Rubik, and introduced by Tomy Toys of Japan in 1981.
Rubik's Clock is a mechanical puzzle invented and patented by Christopher C. Wiggs and Christopher J. Taylor. The Hungarian sculptor and professor of architecture Ernő Rubik bought the patent from them to market the product under his name. It was first marketed in 1988.

God's algorithm is a notion originating in discussions of ways to solve the Rubik's Cube puzzle, but which can also be applied to other combinatorial puzzles and mathematical games. It refers to any algorithm which produces a solution having the fewest possible moves. The allusion to the deity is based on the notion that an omniscient being would know an optimal step from any given configuration.
A combination puzzle, also known as a sequential move puzzle, is a puzzle which consists of a set of pieces which can be manipulated into different combinations by a group of operations. Many such puzzles are mechanical puzzles of polyhedral shape, consisting of multiple layers of pieces along each axis which can rotate independently of each other. Collectively known as twisty puzzles, the archetype of this kind of puzzle is the Rubik's Cube. Each rotating side is usually marked with different colours, intended to be scrambled, then 'solved' by a sequence of moves that sort the facets by colour. As a generalisation, combination puzzles also include mathematically defined examples that have not been, or are impossible to, physically construct.
The Rubik's Cube, a 1974 invention of Ernő Rubik of Hungary, fascinated people around the globe and became one of the most popular games in America in the early 1980s, having been initially released as the Magic Cube in Hungary in late 1977, and then re-manufactured and released in the western world as Rubik's Cube in 1980. As of January 2009, 350 million cubes have been sold worldwide making it the world's top-selling puzzle game. It earned a place as a permanent exhibit in New York’s Museum of Modern Art and entered the Oxford English Dictionary in 1982. The Cube retains a dedicated following, with almost 40,000 entries on YouTube featuring tutorials and video clips of quick solutions.
Eric Limeback is a Canadian speedcuber. He is known for his 11/11 3x3x3 multiblindfold Canadian record solve, as well as his standard 3x3x3 blindfolded solving. Limeback was the first Canadian to record a sub-30 second official 3x3x3 blindfolded solve. Limeback began solving the Rubik's Cube in 9th grade. He graduated from Marc Garneau Collegiate Institute in 2010. He formerly held the Guinness World Record for the most 3x3x3 cubes solved in 24 hours, 5800, set from 3–4 October 2013 at Wilfrid Laurier University, Canada.
Feliks Aleksanders Zemdegs is an Australian Rubik's Cube speedsolver. He is the only speedcuber ever to win the World Cube Association World Championship twice, winning in 2013 and 2015, and is widely considered the most successful and greatest speedcuber of all time. He has set more than 350 records across various speedcubing events: 121 world records, 211 continental records, and 6 national records.
Anthony Michael Brooks is an American speed cubing champion. He specializes in the 2x2 cube and classic 3x3 cube, and has been officially ranked in the top five in the world in both categories as recognized by the World Cube Association. Since learning to solve the cube in March 2008, Brooks has become known for developing advanced speedsolving methods as well as frequently promoting speedcubing in the media. While working as the Liberty Science Center's Speedcuber-in-Residence, Brooks set the Guinness World Record for most Rubik's Cubes solved underwater in a single breath, and also led the team that currently holds the world record for solving the Groovik's Cube, the world's largest functioning Rubik's Cube. In July 2017, Brooks was featured on the debut season of FOX's Superhuman TV show.
CubeStormer II is a robot built primarily with Lego Mindstorms and a Samsung Galaxy S2 for solving a Rubik's Cube. The project was commissioned by ARM Holdings and designed and built by Mike Dobson and David Gilday.
CubeStormer 3 is a robot built primarily with Lego Mindstorms and the Samsung Galaxy S4. On 15 March 2014, at the Big Bang fair in Birmingham, England, the CubeStormer 3 broke the previous record, held by its predecessor, the CubeStormer II, for the fastest time to solve a Rubik's Cube. The previous Guinness World Records time was 5.270 seconds. The official time taken to solve the Rubik's Cube by the CubeStormer 3 was 3.253 seconds. This robot was created by inventors David Gilday and Mike Dobson. It took the two of them 18 months to perfect the technology of this robot. The robot was able to conquer the cube by use of four robotic hands. The robot is made out of LEGO and ARM architecture.
