One of priority tasks of modern society is creation of conditions which help identification and development of gifted children. Training of teachers during which there is an expansion of students' professional competences in diagnosing, supporting abilities and talents of learners, including learners with special educational needs, takes place within the framework of the corresponding master's program. The purpose of the study is to assess the impact of using game mechanics when training master's degree students, future experts in work with gifted children on the quality of their professional training.The methodology is based on the analysis and generalization of scientific literature on clarifying the essence and potential of the phenomenon of "gamification of education" in the context of UNESCO recommendations and development of the digital school, clarifying principles of game mechanics and their limitations for didactics in general and when teaching learners with special educational needs. For practical implementation of game mechanics the mechanics "Achievement", "Joint research", "Restraining factors", "One time fun -always fun", "User progress" were chosen.Research results. Gamification of activities of master's degree students of the experimental group is presented by the authors both in the "computerless" format (business or board game, research project, etc.) and in the Kodu Game Lab environment.
