Buchholz calculator
Add every opponent your team has faced and their current win-loss record. Buchholz is the sum of your opponents' (wins − losses) — the higher it is, the tougher your path and the better your seed among teams on the same record.
Your Buchholz
Sum of every opponent's wins minus losses. Used to seed teams and break ties on the same record.
Which records advance?
In the 16-team Swiss stage, the first teams to 3 wins advance and the first to 3 losses are eliminated. The 3-0 and 0-3 matches are Bo1; every decider (advance or elimination) is Bo3.
| Record | Result | Match format |
|---|---|---|
| 3-0 | Advances | Best of 1 |
| 3-1 | Advances | Best of 3 |
| 3-2 | Advances | Best of 3 |
| 2-3 | Eliminated | Best of 3 |
| 1-3 | Eliminated | Best of 3 |
| 0-3 | Eliminated | Best of 1 |
How the CS2 Major Swiss system works
Every modern Counter-Strike Major uses the same Swiss format. Here's what decides your matchups and your seed.
Seeding by Buchholz
Teams on the same record are ranked by Buchholz — the combined win-loss difference of all the opponents they've already played. A tough schedule pushes you up the seeding.
High vs low matchmaking
Within each record group, the highest seed plays the lowest seed. Buchholz decides those seeds, so your previous opponents directly shape who you face next.
No rematches
You can't face the same team twice in a single Swiss stage. Pairings are adjusted to avoid repeats while keeping the high-vs-low principle.
Bo1 and Bo3 mix
Opening and 0-3 matches are best-of-one; any match that advances or eliminates a team (3-0, 3-1, 3-2, 2-3, 1-3) is best-of-three to reduce upsets where it matters most.

CS2 Major calculator — FAQ
What is Buchholz in CS2?
Buchholz is the tiebreaker used in the CS2 Major Swiss stage. A team's Buchholz is the sum of the win-loss difference of every opponent it has faced. A higher Buchholz means you played tougher teams, so you're seeded above others on the same record.
How does the CS2 Major Swiss system work?
Sixteen teams play rounds where everyone with the same record is paired together. Win three matches and you advance; lose three and you're out. Most teams need three to five rounds to reach 3 wins or 3 losses.
Which records advance at a CS2 Major?
Teams that reach a 3-0, 3-1, or 3-2 record advance to the next stage. Teams that hit 0-3, 1-3, or 2-3 are eliminated. Exactly eight teams advance and eight go home from each Swiss stage.
Are CS2 Major matches Bo1 or Bo3?
Opening-round and 0-3 matches are best-of-one. Every match where a team can advance or be eliminated (3-0, 3-1, 3-2, 2-3, 1-3) is best-of-three.
How is the seeding decided?
Initial seeds come from the previous stage ranking. After that, teams on the same record are re-seeded by Buchholz, and the highest seed plays the lowest seed in each group.
Is this the same as the CS:GO Major format?
Yes. The Swiss system with Buchholz seeding was introduced in CS:GO and carried over to CS2 unchanged, so this calculator works for both CS:GO and CS2 Majors.
