As educational tools, Serious Games (SGs) have been reported to be effective in educational settings including English language learning and teaching; hence, the current study explored the effect of practicing serious games on promoting speaking skills among adult EFL learners. Thirty six EFL learners took part in a five-week experimental study and received 870 minutes of instruction. The participants were assigned to three groups including video game, paper game and a control group based on the results of a pre-test administered earlier. During the learning activities, the first experimental group was instructed on how to improve speaking skills through paper game and the second experimental group through video game while the control group went through conventional teaching of speaking skills. After 10 sessions, the post-test was administered to the three groups to assess the learning achievements. Both qualitative and quantitative data, including learners’ scores, lesson plan and interviews were collected to triangulate and complement the survey results. The results indicated that the groups with video and paper game instructions performed significantly better than the control group. It is hoped that the presented study will provide inspirational guidance for teachers on how to engage EFL learners in meaningful and motivational learning so that the development of basic skills such as speaking can be facilitated.
