Rules

Platform rules & league configuration

Rosterdam sets a few platform-wide standards. Everything else — scoring, roster size, waiver method — is configured by each league's commissioner.

Platform standards

All leagues must have an active commissioner, a published set of scoring rules visible to every member, and a locked lineup deadline before games begin. Manual commissioner corrections are logged and visible to league members.

What each league configures

Starting lineup positions, bench and reserve slots, scoring categories and point values, waiver method (rolling priority, FAAB, or commissioner-processed), trade review rules, and keeper or dynasty eligibility are all set per league.

Fair play

Collusion, roster manipulation to affect other matchups, and abuse of commissioner tools are against platform policy in every league, regardless of individual league settings.

Disputes

Scoring or transaction disputes are first handled by your league commissioner. Platform support steps in for issues commissioners cannot resolve, such as a scoring engine error.
