ABSTRACT: English learning in Nigeria has become imperative and its continuous learning cannot be waved, since it is the official language in Nigeria and an international language for communication. Despite the importance of English language, student's performance in English language in Nigerian secondary institutions has been discouraging. Research has shown that vocabulary is the most important element of any language learning including English language. This paper implemented a mobile gamification learning system for motivating learners to continue learning English vocabularies effectively on mobile devices. The system was evaluated, through an online survey, which was completed by 71 participants with different English vocabulary level abilities. Experimental results revealed that the developed system significantly improve learner's English vocabulary abilities and learning interests.
