2025 Soccer Lightweight, Open & Entry League Rule Releases

Hi Everyone,

Thank you for your patience, we have made significant progress with cleaning the 2v2 Rules this year, reducing the document length by almost 35%. However, we have only listed the changes that change game play or the rule definitions, not to clutter the change-log with the >700 line edits.

Lightweight & Open Gameplay Changes:

  • New 2026 Soccer Ball announcement
  • Removal of Open League weight limit
  • 2025 Brazil International Competition Communications Module announcement
  • Removed restriction on pressurized gas canisters
  • Increased & Unified Kick Power limit (check each league)
  • Removed limit of 2 years in Lightweight League at International Level

Changes Include:

  • Changes from 2024 are in RED within the Rules
  • Moving rules to locations that make more sense
  • Adding the General RoboCup Rules, which are the same for all Leagues
  • Making the Ball Specification & Field Specification sections dedicated documents, linked through the Rules
  • Linking of International Marking / Scoring Rubrics in the main rules
  • Reworking of awkward rule definitions & descriptions (better for translation hopefully)
  • Whole new GitHub Co-Space integration to massively simplify rule editing (Thank you Marek)
  • Removing duplication of rules

Entry League has seen updates as well, but mostly remains the same for formatting.

  • Updated weight limits
  • Additional motors added to Whitelist (We are always open to review more to add)
  • Clause about not using any past 2v2 Robots in any Entry League games

The rules can be found via the links below or via the GitHub / Website.

There also have been major updates to the Website, so check those out as well!
