Join over 30,000 students worldwide in the first-ever eSports league for kids ages 8 to 14! Esports is one of the hottest growing careers in the world. Last year more people watched the eSports finals than the NBA finals!
Black Rocket’s motto is Safe – Fun – Learn. We designed our league, the eSports apps, and our unique online community, the Creator Corps, around those principles. Kids can choose to play either of our exciting games, Sembly® or Battle Royale®. Both empower kids to be creators and makers in a safe environment while learning about STEM careers and level design. Prizes and STEM scholarships are awarded throughout the year for our young designers.
