The race to AC Masters
Every AC Points event adds to one season-long total. Where you finish in this table decides how you enter AC Masters.
Tied teams share a rank. Open a team to see every result it scored.
How AC Points are awarded
AC Masters, AC Community League #2 and AC Youngsters League award no AC Points.
Four paths into AC Masters · 14 teams
Direct to Playoffs
1st–4th in AC Points skip qualifying and the Group Stage, straight into the double-elimination bracket.
Direct to Group Stage
5th–8th skip qualifying and start in the Group Stage.
Closed Qualifier
9th–16th play an 8-team bracket; both finalists reach the Group Stage.
Open Qualifier
Open entry (€15), plus the 6 Closed Qualifier teams that missed out. Three 64-team brackets, points combined.
The 10 Group Stage teams play down to 8, the Pre-Eliminary Round cuts them to 4, and those 4 join the direct invites in an 8-team double-elimination bracket: Bo3 throughout, Bo5 Grand Final on 29 August 2027.
How strong every team is right now
The AC Rating seeds our brackets and groups. It moves after every match and rewards top finishes. It is separate from AC Points, which decide AC Masters.
Rank = order used to fill the seeding pots when registration closes. Ties go to the team with more AC Points. Teams with no matches yet sit at their RCS Class starting value.
Match log
How ACR works
Where ACR is used
- AC Cup: seeding of the single-elimination bracket.
- AC Series: round 1 of the Swiss qualifier; group stage seeded by ACR mixed with qualifier performance.
- AC Championship, AC Challengers, AC Community League: group stage seeding.
- Qualifier matches count toward ACR like any other match.
- AC Masters: seeding is not influenced by ACR.
Starting values by RCS Class
A team with no results starts at its class value.
How a match changes ACR
Every match counts once (a whole Bo3 is one result). The winner takes rating from the loser.
- K is doubled for a team's first 10 matches.
- Score bonus, Bo1: 1 + (round difference − 1) / 12, max 1.5.
- Score bonus, Bo3/Bo5: 1 + (map difference − 1) × 0.25.
- Forfeits: the winner advances, nobody's ACR changes.
Event weight: Cup, Opening, Swiss, Community, Youngsters ×1 · Series ×1.25 · Championship and Challengers ×1.5 · Masters ×2.
Class and roster changes
When a team changes RCS Class, its ACR moves halfway between the old and new class values (G → F = +75), then its next 5 matches count double.
The same applies when 3 or more players of a roster change: halfway back toward the class value, then 5 matches at double weight.
How seeding works: pots and a draw
ACR never pairs the strongest team with the weakest. It only decides which pot a team goes into; a random draw decides the actual matchups.
Knockout brackets · 2 pots
AC Cup, and round 1 of the AC Series Swiss qualifier.
- Pot 1: top half of the field by ACR. Pot 2: bottom half.
- Every first-round match is one Pot 1 team against a randomly drawn Pot 2 team.
- With a Preliminary Round (9–15 teams), the highest-ACR teams get the byes into the Round of 8.
- After round 1, ACR plays no further part: the rest of the bracket follows the draw.
Group stages · one team from each pot
- AC Series (4 groups of 4) and AC Championship (8 groups of 4): 4 pots.
- AC Challengers and AC Community League (4 groups of 3): 3 pots.
- AC Series: the qualifier counts more than ACR. Teams are ranked by qualifier record, then head-to-head, then ACR, so a team is never in a lower pot than a team it beat in the qualifier.
- Teams from the same organisation are kept apart in the first round of the draw.
Placement bonus
The bonus is multiplied by field strength (the event's average ACR ÷ 1,200, between ×0.75 and ×1.5) and counts for 180 days.

Single-format passes
AC Pass · mix any paid formats
An AC Pass covers at least 3 events from 2 or more paid formats (AC Cup €10, AC Series €20, AC Championship €50, AC Challengers €25, AC Masters Open Qualifier €15). AC Challengers and the Masters Open Qualifier can only be prepaid through an AC Pass.
Up to about 25% of each event's field is reserved for pass holders. Guaranteed entry means the first stage only, never a result or a skipped qualifier.
Every ticket is tied to a named event (e.g. AC Cup #2, #7, #10), not a floating credit.
7+ days' notice: full value. 48 hours to 7 days: 50% carries over. Under 48 hours or after the bracket is out: locked.
An unused ticket is lost. A second no-show in the season removes priority access.
Cancel the whole pass any time for 50% back on unused tickets. Tickets never used expire at season end.
The pass belongs to the team, not a player. Refunds go only to the named Payment Contact. Free formats are not part of any pass.
The essentials before you register
Eligibility
All players must be 16 or older, and at least one player or coach must be 18 or older. Your RCS Class must fit the event's range on the day.
Swiss Cup: your team or organisation must be based in Switzerland, or at least 1 of your 5 players must be Swiss.
Entry fees
Charged once per team per event, covering every qualifier leg and the main event. Opening Cup, Swiss Cup, Community League and Youngsters League are free.
Seeding
ACR at registration close splits teams into pots (2 for knockouts, 3–4 for groups) and a random draw sets the matchups. Equal ACR: more AC Points ranks higher. Same-organisation teams are kept apart in round 1.
Prize pools
Pools depend on sign-ups. AC Cup pays €100 with 13–16 teams and €75 with 8–12; below 8 sign-ups the Cup is cancelled and fees refunded.
Schedule
All times CET/CEST. No matches on blackout dates: 21 Dec 2026 – 4 Jan 2027, 14 Feb, 13 Jun and 1 Aug 2027.
RCS Class ranges
Classes run from I (newest) up to B. Each format admits teams from Class I up to its ceiling.
