This meta-analysis aims to investigate gamification's impact on improving tertiary-level second-language learners' lexical repertoire. Forty-seven peer-reviewed works were evaluated for this analysis. The analysis focused on determining the effectiveness of gamified learning environments in the context of improving vocabulary and learning and remembering new vocabulary by learners. This study adopted a meta-analysis review methodology for reviewing the above articles. It explores gamification methodologies, challenges and considerations, the influence of activity-specific experiences, the advancements in Digital game-based learning, the effectiveness of different strategies in gamification, and the perceptions of learners and educators towards gamified tools for learning. After a detailed analysis, the result has shown that the use of gamification-enhanced vocabulary learning is better than that of conventional teaching methods. Consequently, this analysis demarcates the importance of gamification as a lively and captivating means of teaching and learning vocabulary, while making up a significant contribution to the body of knowledge in language learning.
