Speedcubing
Speedcubing (also known as speedsolving, or cubing) 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. An individual who practices solving twisty puzzles is known as a speedcuber (when solved specifically focusing on speed), or a cuber. For most puzzles, solving involves performing a series of moves or sequences that alters a scrambled puzzle into a solved state, in which every face of the puzzle is a single, solid color. Competitive speedcubing is mainly regulated by the World Cube Association (WCA). The WCA currently recognizes 17 speedcubing events: the cubic puzzles from the 2x2–7x7, the Pyraminx, Megaminx, Skewb, Square-1, and Rubik's Clock, as well as the 3x3, 4x4, and 5x5 Blindfolded, 3x3 One-handed, 3x3 Fewest Moves, and 3x3 Multi-blind. , the 3x3x3 world record single is 3.47 seconds held by Yusheng Du. The 3x3x3 world record average is 4.86 seconds, tied by Max ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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, 210 continental records, and 6 national records. Biography Feliks Zemdegs is of Latvian descent and his maternal grandmother is Lithuanian.

Rubik's Cube
The Rubik's Cube is a Three-dimensional space, 3-D combination puzzle originally invented in 1974 by Hungarians, 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 Company, 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 Spiel des Jahres, German Game of the Year special award for Best Puzzle. , 350 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. On the original classic Rubik's Cube, each of the six faces was covered by nine stickers, each of one of six solid colours: white, red, blue, orange, green, and yellow. Some later versions ...

Fridrich Method
The CFOP method (Cross – F2L – OLL – PLL), sometimes known as the Fridrich method, is one of the most commonly used methods in speedsolving a 3×3×3 Rubik's Cube. This method was first developed in the early 1980s combining innovations by a number of speed cubers. Czech speedcuber and the namesake of the method Jessica Fridrich is generally credited for popularizing it by publishing it online in 1997. The method works on a layer-by-layer system, first solving a cross typically on the bottom, continuing to solve the first two layers (F2L), orienting the last layer (OLL), and finally permuting the last layer (PLL). There are 78 algorithms in total to learn for OLL and PLL but there are other algorithm sets like ZBLL and COLL that can be learned as an extension to CFOP to improve solving efficiency. History Basic layer-by-layer methods were among the first to arise during the early 1980s craze. David Singmaster published a layer-based solution in 1980 which proposed the use o ...

Ron Van Bruchem
Ron van Bruchem (born 20 April 1967) is a Dutch speedcuber living in Almere. He helped create the current resurge of Rubik's Cube enthusiasm by founding the international speedcubing community and organizing international competitions. He is also a founder, delegate and former chairman of the World Cube Association, an organization aiming at the spread of speedcubing as a regulated sport. He is also the host of the website speedcubing.com. In 1999 the first modern age speedcubers found each other on internet via Rubik's Games, a computer game with an electronic version of Rubik's Cube. Chris Hardwick from Raleigh, NC founded a Yahoo Group Speedsolvingrubikscube and the Unofficial World Records, a place where cubers could post their personal records. Ron van Bruchem started speedcubing.com together with his friend Ton Dennenbroek, an avid puzzle collector. Because the first cubers were living all over the world they wanted to organize a competition where they could all meet. After ...

Lars Petrus
Lars Erik Petrus (born 4 November 1960 in Luleå in Sweden) is an accomplished speedcuber. In 1982, he became the national champion of Sweden, and went on to finish fourth overall at the first official Rubik's Cube World Championships held in Budapest, Hungary. He later published his method, known as the Petrus system, on the Internet. It became a fairly popular method among intermediate and upper-level speedcubers, although its more recent use has diminished considerably due to the increased predominance of methods such as ZZ, Roux, and CFOP. Petrus won the 3x3x3 Fewest Moves category at the 2005 World Championships held in November 2005 at Lake Buena Vista, Florida, USA claiming the US$500 prize. He currently (since 1995) resides in SF Bay Area, California, USA. The Lars Petrus System The Petrus System was designed as an alternative to the popular layer-based solutions of the early 1980s.
