The goal of this study is to design and develop an interactive mobile game-based application in learning new vocabulary that could serve as a supplementary tool for students learning synonyms, antonyms, and homonyms that would cater to the style preferences of today’s generation with the premise that they learned differently and cannot be just told what to learn but instead through interaction and fun. Rapid Application Development was used in the implementation of the study with the help of elementary school teachers and their students for the content and improvement of game play.
