Transfer Windows and Roster Management

Teams are not static. Players leave, new players join, lineups shift around work schedules and changing goals. In casual scrims and open tournaments the roster is flexible. But in structured leagues, roster changes are regulated - you cannot swap players mid-season unless the league is in an open transfer window. This guide explains transfer windows, tokens, and the rules that govern roster changes.

Why Transfer Windows Exist

A league season is a sustained competition. If teams could swap rosters freely between matchweeks, the standings would become a test of recruiting rather than performance. Transfer windows preserve competitive integrity: you play most of the season with the squad you started with, and you have defined periods where you can make controlled changes.

A typical season structure: pre-season registration window (open roster), the regular season (roster frozen, transfers disabled), a mid-season transfer window (1-2 weeks, roster changes allowed with limits), and end-of-season roster reset for the next season.

The transferWindowOpen Flag

Every league has a transferWindowOpen toggle controlled by the league organizer. When open, captains can add, remove, or swap players under the league's rules. When closed, the roster is locked for the league's competitions - other leagues or open scrims are unaffected.

You see the current status on the league detail page: a green Transfers Open banner or a neutral Transfers Closed state. Organizers announce upcoming window openings in advance so captains can plan.

Transfer Tokens

To prevent teams from rebuilding from scratch during a window, leagues issue transfer tokens - a limited budget of roster changes per team per season. Each add, remove, or swap costs one token. The organizer sets the token budget per league - typical configurations are 6 to 8 per season, but the organizer decides. Once you spend your budget, further changes are blocked by the system until the next window or the next season.

Token counts, window lengths, and the definition of a "change" (e.g. are substitutes counted, does a captain handover cost a token) live in the league's transfer rules and vary league to league. Always read the rules before the season starts so the budget is not a surprise.

Adding Players Outside the Window

Some leagues allow emergency additions - if a roster drops below the minimum size (e.g. players quit or are banned), you can petition the organizer for a single add outside the window. These requests are reviewed case-by-case and usually granted only for genuine force majeure, not convenience.

Adding over the roster maximum (a "stacking" team) triggers the extraPlayerPenalty rule from the league's ruleset - either blocked outright or allowed with a points/ELO penalty, depending on the league.

Transfer History

Every roster change is recorded on the player transfer history: who joined or left, when, and the league it occurred in. This history is public on player and team profiles, so recruiters can see patterns - a player who rotates teams every window might be harder to recruit than a player with a stable history.

Permanent leaves (you quit a team outside a window) are different from temporary roster inactivity (you skip a few matchweeks with the captain's blessing). Only permanent leaves show in transfer history. See the team profile for the full field-level breakdown.

Planning Around the Calendar

If you know you want to make a big roster change - replacing a key position, merging two partial rosters - plan around the window. Announce the change to the affected players well in advance, handle scheduling during the window itself, and start the regular season with the roster you want to finish it with. Surprising a teammate with a post-window release because you ran out of tokens is a reputation hit that follows you to future seasons.
