A mobile based gaming application created to teach computational thinking skills to school going teenagers in underdeveloped areas of Pakistan. We explore the use of gamification to teach computational thinking through level-based learning in a Pakistani context. The final app design demonstrates how gamified learning, rewarding techniques, and feminine themes can be used to attract female teenagers towards computational thinking. The app was evaluated through usability testing, conducted on 16 school-going female teenagers. We hope that through this study, we have taken the first step towards nurturing an interest in young females for computational thinking and overcoming the gender gap that adversely affects female involvement in Computer Science in Pakistan.
