Each tournament is equivalent and the winners, runners-up and two best third placed players of each tournament will qualify to a final-8 knockout tournament.\n\nIMPORTANT NOTES\n\nIf you do not manage to join a specific group you can join one of the remaining ones if there are still vacant places.\nPlayers with ranking between 10-25 kyu are allowed to join the tournament.\nEach player should join a SINGLE group. If someone joins two or more groups, the tournament manager will remove him/her automatically.",
