This paper aims to find out how games are important and effective when used in EFL classrooms. Two different kinds of qualitative research methods: semi-structured interviews and observation were conducted in this study. Multi-method triangulation is used throughout the study. The data was carried out through audio-recorded interview and observation. It is a case study in which two undergraduate students are taught English by using the game called "Twister" which is adapted for teaching. It was determined from the data that games should be employed in second language learning classrooms in terms of providing an atmosphere for EFL learners in which there is fun, motivation, and high learning performance.
