Abstract: The purpose of this research was to investigate the use of games in teaching and learning vocabulary among Vietnamese students and to assess the effectiveness of word games in enhancing English vocabulary acquisition among university students at a university located in Northern Vietnam. The study involved the participation of sixty first-year students from two classes. Data was collected through pre-tests, post-tests, unstructured observations, and informal interviews. The findings of the study revealed a significant statistical difference between the pre-test and post-test scores of the experimental group. Furthermore, a significant statistical difference was observed between the experimental group, which employed innovative game-based methods for vocabulary learning, and the group that followed traditional language teaching methods.
