I am Lucas Etter (lucascube), a professional speedcuber from the United States. I first learned how to solve the Rubik's Cube in 2009, and I became the first person to officially solve the Rubik's Cube in under five seconds in 2015. I have held a total of four world records and four national titles in the 2x2 and 3x3 events. On my channel, you will find videos about my speedcubing experiences and expertise. Enjoy!
