Extending round duration in Rescue Line 2026

Hello everyone,

According to the RoboCupJunior Rescue Line 2026 rules (last updated: 2026-03-29), section 5.3 states:

“Each team has a maximum of 8 minutes for a game.”

I would like to know whether, under the current rules, organizers are permitted to run a significantly more advanced field with a longer round duration (for example, 12 minutes instead of 8 minutes).

Or is the 8-minute limit mandatory and fixed for all official competitions?

Thank you.
