Eric Limeback (born March 3, 1992) is a Canadian speedcuber. He is known for his 11/11 3x3x3 multiblindfold Canadian record solve, as well as his standard 3x3x3 blindfolded solving. Limeback was the first Canadian to record a sub-30 second official 3x3x3 blindfolded solve. Limeback began solving the Rubik's Cube in 9th grade. He graduated from Marc Garneau Collegiate Institute in 2010. Limeback's official YouTube channel has tutorials on how to solve a Rubik's Cube blindfolded. He formerly held the Guinness World Record for the most 3x3x3 cubes solved in 24 hours, 5800, set from 3–4 October 2013 at Wilfrid Laurier University, Canada.
Eric Limeback first began solving Rubik's Cubes at the age of 14 in 2007. Within five months he had entered a Canadian National speedcubing competition, and managed to finish in the top 25 in the country. In 2009 a YouTube video of him solving 11 cubes blindfolded aired on an Oprah Winfrey Show segment. By 2010 he had become one of Canada's top solvers, with a personal best time of as little as 7.1 seconds to solve a fully scrambled cube. He came to national attention in August of that year, becoming involved in a project to create Rubik's Cube mosaics worth tens of thousands of dollars. In 2011 he was the subject of a short documentary called The Cuber for the National Screen Institute. At this time he was already the second fastest cuber in the country. By 2013 he had broken a total of eight Canadian Rubik's records, and was also ranked first in Canada for solving Rubik's cubes blindfolded.
On 3–4 October 2013 Eric Limeback set a world record for solving the most Rubik's Cubes in a 24-hour period. He set the record at Wilfrid Laurier University in Waterloo, Ontario. He had ten cubes set up in front of him for the record breaking attempt, with a team of volunteers randomly mixing up the cubes and handing them back to keep a cube in his hands at all times. In total he solved a Rubik's cube 5,800 times in 24 hours, ending just before 1 pm Friday. He broke the previous record of 4,786 with 4 hours and 7 minutes left. He finished the 5,800th cube in 23 hours, 59 minutes and 59.7 seconds, with an average solve time of 14.89 seconds per cube.
