Format Changes
The format of the 2017 regular summer season gave every team the opportunity to play a best of three for every match. The first team to win two out of the three games, takes the match. Teams played on Friday, Saturday, and Sunday; every Friday two matches were played, and every Saturday and Sunday there were four matches played. Between weeks 5 and 6, the NA LCS took a break to participate in Rift Rivals, a competitive tournament for boasting rights against the
European LCS. In this tournament, North America sent Team SoloMid, Cloud9, and Phoenix1 to represent the region. The 2017 regular summer season started on Friday, June 2, 2017, and by the end of summer, there were nine weeks of competition and over 200 games played.
The top six teams of the regular season earned a spot in the Playoffs. Playoffs consisted of three rounds: Quarterfinals, Semifinals, and Finals. The top two teams from the regular season automatically qualified for Semifinals while the four other teams played in the Quarterfinals. The winners of the Quarterfinals move onto the Semifinals. With the use of dynamic seeding, the highest seeded team, plays against the lowest seeded team that moved onto the Semifinals, and the second highest seeded team plays against the remaining team. The two winners of the Semifinals play in the Finals, while the two losers play for third place.
Quarterfinals and Semifinals played in the Battle Arena while the Finals played at the TD Garden in Boston, MA. All matches are best of five.
