Teams compete in a double round robin tournament over the course of nine weeks during the regular season, with matches being best-of-three. The top six teams from the regular season advanced to the playoff stage, with the top two teams receiving a bye to the semifinals. The seventh place team qualifies for the next split of the LCS but does not participate in playoffs. The bottom three teams play in a promotion/relegation tournament against the top two NA Challenger Series teams. Playoffs were single-elimination and matches were best-of-five. The winner of the summer split automatically qualified for the 2016 World Championship, while the team with the most cumulative championship points from the spring and summer splits also qualified for World Championship. A final team, the winner of the regional finals, also qualified for the World Championship.
