CHEMBINGO is an innovative game-based learning activity aimed at enhancing student engagement and comprehension of the periodic table of elements. By integrating key concepts from the periodic table into a familiar Bingo game format, CHEMBINGO offers a dynamic and interactive learning experience. The study provides a detailed account of the game's design, its implementation in educational settings, and an evaluation of its effectiveness through both quantitative and qualitative measures. Implications for further research are discussed. Keywords: chemistry education, game-based activity, periodic table of elements INTRODUCTION Everything in the world fundamentally constitutes elements and their interactions create the reality that the world is in. These interactions can be observed and understood through chemistry. “In fact, all material objects—whether living or inanimate—are made up only of chemicals…” (Petrucci et al., 2017), and due to the interrelations of chemistry to other scientific disciplines, such as biology and geology, it is considered to be “the central science” (Chang, 2008). “Chemistry is considered one of the cornerstones of science, technology, and society” (Magdara, 2015). Considering this, the study of chemistry becomes significant as it leads to a better understanding of the world on its fundamental level. With this, chemistry education plays a vital role in improving the quality of teaching and research as well as ensuring that students are well equipped with the necessary skills to allow them not just to grasp chemistry concepts but to allow them to contribute something to improving the quality of life (Khanam, 2018). Emphasizing the role of chemistry education, a substantial array of studies has been conducted for its continuous development to meet the demands of changing times. From using concrete manipulative materials and peer interaction (Howe & Durr, 1982), cooperative group work (Basili & Sanford, 1991), and context-
