Serious games (SG) or educational games are complete games designed for a specific purpose that fulfill both their classic function of entertainment and promote the learning of specific concepts or skills and optimize health care in general. In the pediatric setting, these games combine strategies to educate about health issues, promote healthy behaviors, provide therapy or medical treatment. SG have been shown to promote adherence to treatment in children with chronic diseases, reduce anxiety in those undergoing invasive medical procedures, and stimulate the development of cognitive, emotional, or psychomotor skills. However, it is important to emphasize that the success of SG in pediatrics depends to a large extent on game quality, their design based on clear objectives, and their accurate adaptation to the individual needs and preferences of patients.
