Every year FIRST® LEGO® League publishes a challenge, based on a realistic scientific problem. Every challenge has three parts: Robot game, Project and Core Values. Every team has two to ten members and at least one, adult, coach. Teams that take part to the challenge program an autonomous robot and score points on the thematic map (Robot Game), suggest solutions for the problem they have detected (Project) and work always according to the FLL’s values (Core Values).

What is FIRST® LEGO League Challenge;


FIRST® LEGO® League Challenge introduces science, technology, engineering, and math (STEM) to children ages 9-16 through fun, exciting hands-on learning. Participants gain real-world problem solving experience through a guided, global robotics program, helping today's students and teachers build a better future together.

RePLAY Challenge

Opportunities to play are all around us. In the RePLAY Challenge, the creativity of young minds will transform spaces – from open fields to empty parking lots – into opportunities to play. What activities can we create there? How can the games and the places where we play change to reflect the people playing or the equipment we have?
This season, FIRST LEGO League Challenge participants will harness their natural curiosity and use their critical thinking and imagination to explore what future spaces for play will look like. Guided by adult mentors and working as a team, students will apply their STEM skills to participate in an Innovation Project to solve a real-world problem, build and program a LEGO® robot, and compete in an exciting, mission-based Robot Game.
Are you ready to play? Join the FIRST LEGO League community for RePLAY, part of the 2020-2021 FIRST robotics season, FIRST GAME CHANGERS, powered by Star Wars: Force for Change.


Official tournaments must follow the judging and awards structure determined by FIRST LEGO League. Although the audience mostly sees teams playing the Robot Game at tournaments, teams are also being judged on:

• Core Values
• Project
• Robot Design

Every team’s evaluation is done through the official rubrics of FIRST@ LEGO@ League. Rubrics are evaluation sheets that judges fill for every team. They capture the way teams worked on the three basic competition’s parts that mentioned above.

FIRST LEGO League’s judges, have trained properly by the Head Judge and have received the necessary certification in order to participate in the judgment procedure of the teams.
