Each of 14 premier League of Legends leagues have a team representing them; Europe (EU LCS), South Korea (LCK), North America (NA LCS) and China (LPL) had their teams automatically admitted into the main event whereas the other 10 leagues will compete among each other in a "play-in" with the top 2 teams advancing to join the main event.

The tournament was hosted in Germany and France from 3 to 20 May 2018. Matches of the play-in and group stages were held in EU LCS Studio in Berlin, while playoffs took place in multi-purpose indoor arena Zénith Paris.
