 The qualifying and project development stages will be held in an online format, however, the final round will be in a hybrid mode (offline + online). The competition involves monthly updates from the teams with regular feedback from the jury. All teams are required to prepare a final video and presentation on the project's results to participate in the final stage.

 Отборочный и проектный этапы конкурса проходят в онлайн-формате, формат проведения финала – гибридный (оффлайн + онлайн). Конкурс подразумевает ежемесячные апдейты от команд с получением регулярной обратной связи от жюри. Для участия в заключительном этапе необходимо подготовить финальное видео и презентацию о результатах проекта.
