'Don't catch me if you can' is real-world gamification of the spread of the SARS-CoV-2 virus indoors. The serious game includes tasks like opening vents or changing ventilation rates to learn how to make design decisions to reduce virus spread indoors. The game has mask on/off modes to see its implication on occupants' health. This allows training Architecture, Engineering, Construction and Operation experts by using precise models of the virus and buildings. We use a model of a well-known case of a restaurant in Guangzhou, China. The game will include coughing, singing, locking down sections of the building and more.
