How a Counter-Strike Major works: Challengers, Legends, Champions

The Four-Stage Layout

The Major format has three Swiss-stage rounds and one single-elimination playoff at the end. In total, 32 teams are invited to the event. The breakdown is 16 teams in the first stage, 8 in the second, and 8 invited directly to the third. This 32-team definition of the Major field is set in Valve's rulebook.

Valve's rulebook defines the Major structure as three identical Swiss rounds—Stages 1, 2, and 3—followed by Playoffs, an 8-team single-elimination bracket. All elimination and advancement matches, including in the Swiss rounds, are best of three.

Stage 1: the First Swiss Cut

All 32 teams start the tournament in Stages 1, 2, or 3 based on their invite ranking. The first stage is a 16-team Swiss bracket. Teams are paired up to start, then advanced or eliminated based on their results across the Swiss rounds.

The top 8 teams from the first Swiss round move into Stage 2, with the rest eliminated. The second stage is an identical 16-team bracket, with 8 Stage 1 survivors seeded into it. Again, eight move on to Stage 3, and eight more are eliminated.

Stages 2 and 3: Repeating the Process

The third stage of the Major works exactly like the first two. It is a third 16-team Swiss bracket seeded with 8 teams from the second stage, along with the 8 new invitees. All matches, including those in Stage 3, remain best of three.

From the third stage, the top 8 teams advance to the Major Playoffs bracket. These top 8 are positioned into the playoff bracket according to their finish in the Stage 3 Swiss bracket. Teams 1 to 8 are the final 8 remaining, seeded into the bracket according to their Stage 3 finish.

Why Playoffs Are Different

The Major Playoff Stage is not a continuation of the Swiss rounds, in which teams move up, down, and out based on their performance. Instead, the best 8 teams from the final, third Swiss bracket are entered and seated in the playoff bracket. The playoff bracket's structure is 8 Team single-elimination, with the matches played as best of three.

The Swiss rounds are designed to filter out the lower performance teams as they compete through three rounds of progression and elimination. Each Swiss stage gives teams the opportunity to perform or be eliminated. The final bracket is the time for the tournament favorites to secure the Major's top standing.

What a Major Means Beyond the Trophy

The Major is tied to Valve’s regional standing system, which determines invitations to the next Major and other official tournaments. The event is also part of the standardized framework for official CS2 tournaments used by tournament organizers for flagships and qualified events.

While the Major trophy is the headline prize for teams, the Major also carries non-trophy rewards tied to Valve's standing system. These benefits, however, also require separate verification if included.

Naming the Stages

The tournament's tournament stages have had different names over time. Historically, the stages used to be called Challengers, Legends and Champions. The current Valve naming, however, is Opening Stage, Elimination Stage, and PlayOff Stage, used in keeping with other Valve events.

The Bracket Becomes Knockout

The Major structure sets up an intense final bracket. The top 8 teams left race each other in a knockout single elimination played as best-of-three single-elimination matches until two teams remain to meet in the final. It is a brute run through of the top surviving teams from the three round Swiss structure as they compete for the Major title.
