This study examined how effective online educational games are regarding the improvement of learning vocabulary when learning a foreign language, focusing on using the Educaplay platform. Therefore, this study explored students' perceptions, measuring vocabulary acquisition, and assessed the influence on motivation and engagement. A sequential explanatory mixed methods design was applied to pre- and post-tests, surveys, and focus groups. This study involved two focus groups of Seventh-grade EFL learners: the experimental group, which participated in Educaplay-based vocabulary activities four times a week for eight weeks, and the control group, which followed a traditional vocabulary learning approach. The tests gave quantitative information to measure vocabulary progress, while surveys and group discussions gave descriptive details about students’ attitudes and thoughts on using online games for learning new words.
