Zemdegs bought his first speedcube in April 2008 inspired by speedcubing videos and tutorials on YouTube. The first unofficial time he recorded was an average of 19.73 seconds on 14 June 2008. He currently uses CFOP to solve the 3x3x3 cube, Modified Yau method to solve the 4x4x4 cube and the CLL method with EG-1 and EG-2 to solve the 2x2x2 cube.
At his next competition, the Melbourne Summer Open (January 2010), Zemdegs set his first world records for 3x3x3 and 4x4x4 average, with times of 9.21 seconds and 42.01 seconds respectively.
The most world records he has ever held at one time was after the competition in Melbourne in May 2011 where he held all 12 records listed in the first 12 columns of the table below. He also took first place in 4x4, 5x5, and 2x2.
He also placed second in 6x6, 7x7, and Megaminx. The following are the official speedcubing world records set by Zemdegs that are approved by the World Cube Association.
