Brawl Stars and Duolingo Launch Global Mascot Crossover

On September 17, 2026, Brawl Stars and Duolingo announced a global in-app crossover event set to take place from September 19 to September 30. In this collaboration, Duolingo's mascot Duo will take over as the new boss in Brawl Stars, inviting players into his classroom to complete a series of challenges. Meanwhile, Spike, the mascot from Brawl Stars, will appear in Duolingo's lessons, where users can unlock him by completing daily lessons. This event not only provides players with a fresh gaming experience but also enhances interactivity by rewarding players for answering quizzes correctly. From an industry perspective, such crossover collaborations are noteworthy as they not only engage existing users but also have the potential to attract new users, thereby increasing the activity and stickiness of both applications.
