IEM Season XI : Katowice
Rules
Format

12 teams in two round robin groups of six. The winners of each group are placed into the tournament’s semifinals, while the second and third place finishers also have a playoff to decide who goes to the semifinals.

Tiebreaker

If a three-way tie occurs between the teams in fourth to sixth place, the total prize money for these slots will be split among them. If a three-way-tie occurs for any other three places, it will be decided in the following way:

The three teams decide their ranking order by playing three overtimes against each other
Overtime will be played for the tiebreakers, with a single map selected via veto with all teams participating in the vote
The tiebreaker is over when one team wins two matches during the first three matches - if each team wins a single match, the process is repeated
