Riot Games, the video game company that made one of the world's most popular eSports games, "League of Legends" (LOL), released the group division for the coming LOL Mid-Season Invitational (MSI) on Tuesday.

This year's MSI is happening in Reykjavík, capital of Iceland between May 6 and 22. The 12 teams from the 12 leagues around the world will be divided into three groups like the following:

Group A: League of Legends Pro League (LPL, Chinese mainland), Vietnam Championship Series (VCS, Vietnam), League of Legends Continental League (LCL, Russia) and League of Legends Circuit Oceania (LCO, Oceania)

Group B: League of Legends European Championship (LEC, Europe), Pacific Championship Series (PCS, Taiwan, Hong Kong, Macao and Southeast Asia), Turkish Championship League (TCL, Turkey) and Campeonato Brasileiro de League of Legends (CBLOL, Brazil)

Group C: League of Legends Champions Korea (LCK, South Korea), League of Legends Championship Series (LCS, North America), Liga Latinoamérica (LLA, Latin America) and League of Legends Japan League (LJL, Japan)

Every team in each group will meet the other two teams twice in Best of One Game (BO1) competitions. The top 2 teams will enter the next round. Judging by the performances of teams from these leagues in international events in recent years, it should not be any problem for teams from the top 3 leagues, LPL, LES and LCK to make it to the next stage No. 1 of their group.

The six teams will be in group in the second stage and play each opponent twice in BO1 before top 4 teams are decided for the final stage. The final 4 will compete two pairs compete in Best of Five Games (BO5) form until one team wins the final championship.

Moreover, Riot Games will re-rank all 12 leagues after MSI and give the top one an S11 spot as well. If the champion team comes from the top league, then the league of the runner-up team will receive that extra qualification.
