WCA

Gilles was a member of the World Cube Association Board from October 2004 until 1 November 2008. During his time as a board member, Gilles helped organize many competitions as a WCA delegate. He also contributed to WCA by creating much needed regulations which would in turn help out cubers all over the world. Presently, Gilles is a technical advisor for the WCA and assists when needed.

Roux method

Over a span of years, Gilles developed his own method to solve the 3x3x3 cube. Using a smaller quantity of memorized algorithms than most methods of solving, Roux still found his method to be fast and efficient. The first step of the Roux method is to form a 3×2×1 block. The 3×2×1 block is usually placed in the lower portion of the left layer. The second step is to create another 3×2×1 on the opposite side. The remaining four corners are then solved using a set of algorithms known as CMLL (Corners of the Last Layer, without regards to the M-slice), which leaves six edges and four centers that are solved in the last step.

Official results

For official results, solves must be completed in a competition held by the WCA. In competition, Gilles has recorded a single solve of 10.06 seconds, ranking him just out the top one thousand solvers in the world (as of 1 January 2015). His best average of 5 was set on 16 September 2011 at 13.03. [2] Also his greatest achieved fewest moves competition for the standard 3x3x3 is 31, being part of the "31 club", coming to a draw with another known cuber and creator of popular method of solving, Lars Petrus.

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 Rubik's Revenge is a 4×4×4 version of the Rubik's Cube. It was released in 1981. Invented by Péter Sebestény, the cube was nearly called the Sebestény Cube until a somewhat last-minute decision changed the puzzle's name to attract fans of the original Rubik's Cube. Unlike the original puzzle, it has no fixed facets: the centre facets are free to move to different positions.

Optimal solutions for Rubik's Cube refer to solutions that are the shortest. There are two common ways to measure the length of a solution. The first is to count the number of quarter turns. The second is to count the number of outer-layer twists, called "face turns". A move to turn an outer layer two quarter (90°) turns in the same direction would be counted as two moves in the quarter turn metric (QTM), but as one turn in the face metric.

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. An individual who practices solving twisty puzzles is known as a speedcuber, 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.

The Square-1 is a variant of the Rubik's Cube. Its distinguishing feature among the numerous Rubik's Cube variants is that it can change shape as it is twisted, due to the way it is cut, thus adding an extra level of challenge and difficulty. The Super Square One and Square Two puzzles have also been introduced. The Super Square One has two additional layers that can be scrambled and solved independently of the rest of the puzzle, and the Square Two has extra cuts made to the top and bottom layer, making the edge and corner wedges the same size.
