The competition was organised by Trumptech, SenseTime and Hong Kong Association of Computer Education (HKACE), which aim to motivate students to learn to code and to brush up their computational thinking through the CodeN'Sim Online Coding platform and O2O coding challenges. We are honoured to have 58 primary schools participating in the competition qualifying stage, with 30 schools entering the final. With 1-3 students in a team, the competition has engaged over 170 students, not to mention that selected coding activities were accessible grade-wide for the participating schools to create a broader code-learning experience.
