World Rubik's Cube Championship 2011 (usually called World Championship 2011, abbreviated to WC2011) was a speedcubing World Championship held at the Baiyoke Sky hotel in Bangkok, Thailand on Oct 14-16, 2011. It was the first time the world championship had occurred outside of Europe or North America. Michał Pleskowicz won the 3x3 speedsolve with an average of 8.65 seconds. Rowe Hessler finished second (9.56) and Feliks Zemdegs finished third (9.58).


The tournament took place at the Baiyoke Sky Hotel in Bangkok; with 88 floors it was Thailand's tallest hotel. A year earlier the first ever Asian Championship had taken place at the hotel. Main stage for WC2011 was on the 17th Floor of the hotel, with side events taking place on the 19th Floor. A total of 332 competitors were registered for the tournament, of which 130 were from Thailand.[1]

Unlike the previous two world championships, there was no qualification rounds on the Friday for late entrants. The competition kicked-off on Friday morning with the final of the 3x3 Multi-Blindfold event, together with the first rounds of events such as 6x6 and 7x7 cubes. The finals of the 4x4 Blindfold and 5x5 Blindfold were on Friday afternoon. Saturday saw an Opening ceremony (at 9:40 am) and, as well as many first rounds, there were also the finals of the Fewest Moves and the With Feet events. Sunday saw the remaining semi-finals and finals take place. The final event was the 3x3 speedsolve conducted between 6:45pm and 7:45pm. This was followed by a "Traditional Thai show", and then the Winner's Ceremony and After Party.[2]

The winner of the 3x3 speedsolve won €5500 with winners of other events winning €550 to €1100. The winners of 6x6 and 7x7 events as well Megaminx, Pyraminx, Clock, Square 1, and Magic events only won trophies, meaning even fewer events had cash prizes than WC2009. There was however a Lucky Draw with a top prize of €800.[3]


3x3 Speedsolve

Through 2010 and 2011, Feliks Zemdegs had been considered the favorite by far to win. Although Feliks outperformed other competitors as expected in all other rounds, the final round saw a major upset, with Michał Pleskowicz placing first with a PB official average of 8.65, Rowe Hessler second with 9.56, and Feliks a close third at 9.58. videos reconstructions

5x5 Speedsolve

5x5 was expected from the outset to be highly competitive, with Yu Nakajima's comeback, and recent average world record holders Dan Cohen (defending champion) and Kevin Hays competing against Feliks. Feliks set the tone event with a world record single in the first round, the first ever sub-1 single at 59.27. This was followed in the second round by WR-NAR-AsR top 3 in the second round by Feliks (1:04.08), Dan (1:08.12), and Nakajima (1:08.17), closely followed by Kevin (1:08.72).

After another sub-1 (59.59) and a new world record single of 58.41 by Feliks on the first two solves, Nakajima broke the AsR single on the fourth solve at 58.53, the first sub-1 AsR. Not to be outdone, Dan breaks Feliks's record with 57.44 on the last solve. With all pressure on him, Feliks then yet again improved the world record single with 56.22 (video), demoting Dan's single to a NAR, and ending with a 59.44 world record average, the first official sub-1 average only weeks after his unofficial sub-1 average video. Although Dan and Nakajima both had a better average in the second round, the sub-1 single and world record battle, so soon after the first ever official sub-1 single, has led a number of cubers to declare the final round the most epic round in the history of competitive cubing.
