This saturday, Saturday the 25th, there will be a 5v5 summoners rift tournament with ingame prizes. The tournament will start at 8:00 CET and you can sign up as a 5-man premade or as a free agent (solo-player). Just be warned that not all free agents will be able to play, and dont forget to sign in quickly as the brackets only allow for 15 teams! Best of luck on the rift summoners!
