The fastest time to solve a 3x3x3 rotating puzzle cube is 3.47 seconds by Yusheng Du (China) at the Wuhu Open 2018 in Wuhu, Anhui province, China, on 24 November 2018. This is the first sub-4-second solve of a cube by a human in a World Cube Association event.
Du, who until this point had never broken a rotating puzzle cube record, shaved 0.75 seconds off the time of 4.22 seconds achieved by Australia's Felix Zemdegs on 6 May 2018. Although the attempt was not filmed, security footage was release by the event organizers showing the moment of his solve, and World Cube Association delegates Chenxi Shan and Fangyuan Chang were on-hand to confirm the legitimacy of the scramble and the solve.
