Background: Interpersonal conflicts occur in any kind of social relation, including the field of sports. Proper emotional management can improve athletes’ well-being, coexistence, and performance. This study presents the initial results of the gamified emotional education program Happy Sport in a sample of athletes in the field of non-formal education. Methods: The study sample consists of 194 athletes from the benjamín and alevín categories (3rd- to 6th-grade primary school children). A quasi-experimental pre-intervention and post-intervention design with a control group is followed using the Games and Emotions Scale (GES), Social Support Scale, Emotion Regulation Questionnaire for Children and Adolescents (ERQ-CA), and Bullying in Sports Questionnaire. Results: Statistically significant differences were found across participants in the experimental group between the pre- and post-intervention evaluations for the variables satisfaction and bullying. An analysis of the competencies related to emotion regulation revealed significant results for the experimental group for both scales (cognitive reappraisal and expressive suppression). Conclusions: The results show that after a training session with the gamified software Happy Sport, children’s satisfaction increased and bullying levels decreased. Changes in cognitive reappraisal and expressive suppression may also be explained by the training received.
