What rules and checks apply in a league?

Playbox checks these rules in a league:

• Teams apply only until the registration deadline and before the schedule is generated. League staff can still edit season rosters after the deadline.

• A team needs at least as many members as the format to apply (6 for 6x6). The team owner or captain invites more players first, and they accept.

• The team limit can’t be lower than the number of approved teams.

• A player can be in only one team’s roster per league, unless “Players in multiple teams” is on.

• Only season roster players who are not suspended can be put into a league match.

• The table order is fixed: points, then fewer games played, then goal difference, then goals scored. Head-to-head is not used and can’t be configured.
