Gilles Roux (born 20 January 1971) is a French
speedcuber
Speedcubing or speedsolving is a competitive mind sport centered around the rapid solving of various combination puzzles. The most prominent puzzle in this category is the 3×3×3 puzzle, commonly known as the Rubik's Cube. Participants in this ...
primarily known for inventing a 3x3x3
Rubik's Cube method, the Roux Method, and achieving fast times with it.
World Cube Association
Gilles Roux 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 Roux developed his own method to solve the 3x3x3 cube. Using a smaller quantity of memorized

s 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
Competition is a rivalry where two or more parties strive for a common goal which cannot be shared: where one's gain is the other's loss (an example of which is a zero-sum game). Competition can arise between entities such as organisms, indi ...
held by the WCA. In competition, Gilles has recorded a single solve of 10.06 seconds, ranking him in the top twenty thousand solvers in the world (as of 1 January 2025). His best average of 5 was set on 16 September 2011 at 13.03.
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.
