This robotics season, we’re stepping into the world of sports, play, and fitness – moving, collaborating, competing, and celebrating. In RePLAYSM, FIRST® LEGO® League Challenge students will explore the activities we can do in different spaces for play and how we can ensure that our games and activities are fun and accessible for everyone involved.

Get started by signing up below to receive details about the season, resources for remote participation, and how to join our accessible, fun hands-on learning program.

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.


Friendly competition is at the heart of Challenge, as teams of students ages 9-16* engage in research, problem-solving, coding, and engineering – building and programming a LEGO robot that navigates the missions of a robot game.

NEW: Using Google Classroom, you can experience FIRST LEGO League Challenge no matter where your team members and students are learning this season. To complete the activities, each student will need a LEGO Education robot and three (3) RePLAY Mission Models from the RePLAY Challenge Set. Purchase additional Challenge Sets and Mats in the FIRST Dashboard (subject to availability). Check out the Challenge Guide for Distance Education.

A group of up to 10 students (ages 9-16*) and at least two adult coaches make up a FIRST LEGO League Challenge team. No technical experience is required, and all skills levels and interests are welcome. Our guides break down the season into 12 accessible sessions and provide starting points for exploration into the season Challenge and Robot Game.

Please note FIRST does not match children to existing teams due to our privacy policy. We encourage individuals looking for a team to contact their local schools, libraries, or youth organizations that may have a team in place or interest in starting one.

The FIRST LEGO League Challenge season culminates with tournaments, where teams present their Innovation Project and receive valuable feedback from volunteer judges on their robot, code, and invention. The final test comes at the Robot Game table, where they race against the clock for a personal best score. Tournaments vary by region and run from November – April.

FIRST Program Delivery Partners run local FIRST LEGO League Challenge tournaments, which may include physical, remote, or a combination of physical and remote elements. Team Registration does not guarantee that events are available in your area. Partners may charge an additional fee to participate in their events, and those fees are set and collected by the Partner.

FIRST IS More than just robots…


Evidence from our ongoing longitudinal study is demonstrating that FIRST is meeting its mission goals to increase the number of young people interested in STEM – and their interest extends beyond their participation in the program to their educational and career choices. In addition to gains in STEM outcomes, FIRST participants develop skills in teamwork, problem solving and communication, preparing them for success in school and the future workforce.
