With over 100 million players a month, “League of Legends” is the leading game in professional gaming, or “esports.” In “League,” players act as “summoners” to control characters called “champions” and battle it out in a complex five versus five battle arena. The game held its annual World Championship from Sept. 23 through Nov. 4 in four different venues across China.

This tournament has twenty-four qualifying teams from South Korea, North America, China, and Europe. Based on their performances in their respective regions, twelve of these teams were eligible to head straight into the group stage round. The remaining twelve participated in the play-in stage, a best-of-three round to determine eight more teams who could reach the group stage.

The group stage consists of a best-of-three round-robin style competition to further narrow the number of competitors. In this year’s tournament, reigning world champions SK Telecom T1 from South Korea made it past the group stage. Other competitors who advanced included South Korea’s Longzhu Gaming, China’s Royal Never Give Up, Europe’s Misfits, and North America’s Cloud9.

Following the group stage was the first round of the knockout stage, the quarterfinals of the overall tournament. SKT T1 barely survive against the Misfits with a score of 3-2, while the team with the expectations to win it all, Longzhu Gaming, shockingly lost, 0-3, to Samsung Galaxy. In the semi-finals, SKT T1 continued to edge out their opponents, winning 3-2 over Royal Never Give Up. Samsung Galaxy won 3-1 over Team WE, joining SKT T1 in the finals.

The outcome of the 2017 World Championships resulted in one of the greatest upsets in the game’s history. SK Telecom T1, holding the highest record of wins at the World’s Championships with three wins, was surprisingly defeated by Samsung Galaxy in a devastating 0-3 loss. Often noted as the best “League of Legends” player in history, Sanghyeok “Faker” Lee of SKT T1 seemed emotionally distraught as Samsung Galaxy shook their opponents’ hands, further shocking fans and spectators.

Samsung Galaxy took home their second World Championships title, proving their strength over favorites like Longzhu and SKT T1. They were awarded the Summoner’s Cup and over $1.5 million. The 2017 World Championship boasted a prize pool of over $6 million with 60 million unique spectators, making it the most successful “League” tournament thus far.
