Riot have announced details about First Strike: CIS. The tournament format follows that of the other regions with the first open qualifier starting on November 9 leading to a grand final on December 6.

Open qualifiers will take place over two weeks from November 9-12 and then from November 16-19. These two open qualifiers, which will start with a maximum of 512 teams, will be played in two stages. The first stage will narrow the pool through a Bo1 single-elimination bracket until 32 teams remain. The advancing teams will play out a Bo3, single-elimination bracket until the top four teams are determined that will qualify for First Strike.

The eight qualifying teams will compete in the main First Strike event on December 3-6 in a single-elimination Bo3 bracket with a Bo5 grand final.

Players must be at least 16 years old and have reached at least Diamond 1 before registering for the competition. All rules are available on the Riot website.
