<![CDATA[This study investigates the relationship between the use of online mobile games and the development of English language and soft skills among vocational high school students. Using a mixed-methods approach with a one-group pre-test – post-test design, the study involved 41 students from a vocational high school in Ambon. Quantitative data were collected through vocabulary and pronunciation tests and a soft-skills questionnaire, while qualitative data were obtained through observations, interviews, and field notes. The intervention was conducted over four weeks using Mobile Legends, Free Fire, and PUBG as structured learning media. The quantitative results showed statistically significant improvements in vocabulary, pronunciation, critical thinking, problem-solving, and teamwork scores from pre-test to post-test, with large effect sizes. Qualitative findings indicated that students experienced repeated contextual exposure to English, opportunities to imitate authentic pronunciation, and collaborative situations that required strategic decision-making and problem-solving. Students also reported positive perceptions of the learning activities, particularly in terms of motivation, engagement, and confidence. Taken together, the findings suggest that structured use of commercial online mobile games can provide meaningful opportunities for English language practice and soft skills development in vocational education. The study contributes to game-based learning research by highlighting how commercially available games can be integrated into structured EFL activities in a vocational high school context.]]>
