Project-based learning is an effective method for students' learning design. For the "Graphic Design for Interactive Entertainment" elective course, the author uses project-based learning to teach UI and UX design to Universitas Pelita Harapan's Visual Communication Design Department students. For the project, the author designed a game mechanic. The students of the course later designed visuals for the game. One game that resulted from this project was "Pro Pickpockets", a game about a group of pickpockets competing to collect valuable prizes for the best pickpockets. This paper elaborates on the design case of Pro Pickpockets as a design project and project-based learning for students in learning UI and UX.
