FIRST LEGO League Challenge teams prepare all season to compete at regional tournaments, where judges provide valuable feedback on their robot, code, and invention. The final test of their work comes at the Robot Game table, where they race against the clock for a personal best score and the chance to advance to a local championship. Some teams earn an invitation to FIRST Championship, where teams from all over the world meet and compete. FIRST LEGO League Challenge event timelines and registration process vary by region.
