    This study evaluated a gamified drill and practice mobile application developed to enhance students’ mastery of the Use-of-English component of Nigeria’s Unified Tertiary Matriculation Examination (UTME). The mobile app, designed using the Octalysis Gamification Framework and past Joint Admission and Matriculation Examination questions of Use-of-English, was developed through the ADDOE model which is an adaptation of the ADDIE instructional design model that incorporates the Octalysis phase. Evaluation of the app involved both expert assessment and student testing. Educational Technology and English Language experts assessed the app for content validity, usability, functionality, and pedagogical soundness. A quasi-experimental design was also adopted involving 223 UTME candidates selected using snowball sampling technique. Data were gathered through expert rating scales, a Use-of-English performance test, and a learner engagement questionnaire. Findings revealed high expert ratings across all dimensions. Participants showed improved performance between the pretest and posttest, showing higher motivation and significant improvement in post-test scores. The study concludes that the gamified app is a valid and effective instructional tool for UTME preparation and recommends its integration in language tutorial programs.
