The purpose of this research is to investigate and compare research literature. These articles are related to the use of digital games-based learning to develop Mathematics education and diet food and nutritional knowledge in primary school students (Generation Z), covering game learning theories, their impact on learning, and the promotion of teamwork skills. The articles are obtained from up-to-date academic journal databases. The analysis concludes that most digital games are played on personal computers or computer tablets in offline mode. Playing digital game-based learning has a positive effect on intellectual intelligence in Mathematics education and diet food and nutrition. Our systematic review of 13 recent studies reveals that learning through digital games (DGBL) demonstrates measurable advantages over traditional teaching methods, with studies showing 24–36% improvement in engagement, retention of knowledge, and practical application of mathematical and nutritional concepts. Although short-term benefits are well documented, our analysis points to the need for long-term research studies to assess the long-term impact of DGBL on intellectual development.
