This paper presents a high-fidelity prototype of a mobile game for teaching children fundamental skills in first aid. The study utilizes expert interviews to define learning scope and evaluate design. The game introduces two situations based on realistic scenarios; a boy who fell on a skateboard, and an elderly man with chest pains. Interactive elements introduce a way for the user to explore and assess a given situation. Gamification keeps motivation for learning high, and choice of graphical elements keeps situations feel familiar but non-frightening. There is a quiz to help children learn how to communicate with emergency services. Experts believe that children can learn essential steps for providing basic first aid, except physically fatiguing techniques, so they found the prototype to be a viable option for learning basic first aid at a young age.
