The four major regions
League of Legends competitive play is organized into regional leagues that feed into two main international tournaments each year: the Mid-Season Invitational (MSI) and the World Championship. The four regions with dedicated franchised leagues are South Korea (LCK), China (LPL), Europe (LEC), and North America (LCS).
League formats and structure
| Region | League | Teams | Regular Season | Playoff Teams |
|---|---|---|---|---|
| South Korea | LCK | 10 | 20 weeks, 2 splits | 6 (top 6 advance) |
| China | LPL | 17 | 20 weeks, 2 splits | 8 (top 8 advance) |
| Europe | LEC | 10 | 18 weeks, 2 splits | 6 (top 6 advance) |
| North America | LCS | 10 | 18 weeks, 2 splits | 6 (top 6 advance) |
All four regions operate on a split system, running a spring and summer season. The LCK and LPL play longer regular seasons than their Western counterparts, reflecting differences in team depth and scheduling demands.
Playoff structures
LCK playoffs use a round-robin format among the top six teams, with points determining seeding into a bracket stage. The summer playoffs determine the regional representative for Worlds.
LPL playoffs feature an eight-team bracket with a double-elimination pool in the first round. Winners advance to a single-elimination bracket. Summer playoffs crown the LPL representative for Worlds.
LEC playoffs use a best-of-five bracket among six teams. The spring split winner gets seeding advantages and a potential bye, while summer determines the regional Worlds slot.
LCS playoffs follow a similar six-team bracket format with best-of-five matches. The spring champion receives benefits heading into summer finals, but only the summer split winner qualifies directly for Worlds.
International qualification
Worlds: Each region sends representatives based on their summer split results. The regional champion qualifies automatically. Additional slots go to the runners-up and third-place finishers, varying by regional strength rating. The LCK and LPL typically receive three slots, while LEC and LCS receive two or three depending on prior year performance.
MSI: Spring split champions from each region qualify. MSI also determines the Worlds play-in seeding for non-major regions.
Regional playstyles
LCK emphasizes macro play, wave management, and team coordination. Teams prioritize scaling and efficient map control over early aggression. Vision control and rotational discipline define the region's identity. The LCK has historically produced strong support players and junglers who excel at tracking and neutralizing threats.
LPL favors individual mechanical skill and early skirmishing. Teams fight frequently in the early game and aim to snowball advantages. The region values playmaking and high-risk, high-reward teamfights. Laning phase aggression and mid-game teamfight prowess characterize top LPL teams.
LEC balances macro structure with proactive early-game engagement. European teams typically draft for teamfight power and execute well-coordinated multi-person plays. The region produces inventive champion picks and flexible adapters. Mid-lane priority has historically been a trademark.
LCS has evolved through various strategic eras but currently emphasizes scaling compositions and farm-heavy approaches. North American teams tend toward longer, more methodical games. The region focuses on individual skill expression and teamfight execution, though macro game remains secondary to mechanical outplays.
Path to Worlds
For teams outside the automatic qualification slots, the regional play-in tournaments and Worlds qualifying events provide additional opportunities. Spring split performance can influence MSI seeding but does not directly determine Worlds participation. Only summer split success guarantees or significantly aids a team's path to the World Championship.
