He is the only person to have won the World Cube Association World Championship twice consecutively, in 2013 and 2015, and is often considered the greatest speedcuber of all time.[2][3] He has set more than 350 records across various speedcubing events: 121 world records, 223 continental records, and 7 national records.[4][5]

Biography

Feliks Zemdegs is of Latvian descent, and his maternal grandmother is Lithuanian.[6] Zemdegs bought his first speedcube in April 2008 after being inspired by speedcubing videos and tutorials on YouTube.[7] The first unofficial time he recorded was an average of 19.73 seconds on 14 June 2008.[8]

Zemdegs has a website, CubeSkills, which includes tutorials on solving the Rubik's Cube and other puzzles. There are free algorithm sheets and speedsolving tutorial videos. The site also offers a premium membership which enables access to advanced speedsolving videos.[9]

Zemdegs attended St Kevin's College, Toorak, and graduated in 2013 with a perfect study score in VCE English and an ATAR of 99.90.[10][11] Zemdegs has a Bachelor of Commerce from the University of Melbourne, majoring in economics, with a breadth study track in mechanical engineering.[12] Zemdegs currently works in investment finance.[13][14]

In 2020, Zemdegs was one of the primary subjects of the Netflix documentary The Speed Cubers.[16]

Zemdegs won the 3×3×3 event at the first competition he attended, the New Zealand Championships 2009 on 18 July 2009, with an average of 13.74 seconds in the final round. He also won 2×2×2, 4×4×4, 5×5×5, 3×3×3 blindfolded, and 3×3×3 one-handed.[17] He set 11 Oceanic records at this competition.
