Using an integration of the Attention, Relevance, Confidence, and Satisfaction (ARCS) model and the Self-Determination Theory (SDT). This study explored university students' motivation to learn through the use of gamification. A quantitative approach was used to obtain data from 60 students who participated in a gamified course utilizing a closed-ended questionnaire. The students were chosen using a random sampling method. Structural equation model (SEM) was used to assess the collected quantitative data. It was revealed through the study that the satisfaction attribute of motivation influences students' engagement in learning whereas attention, relevance, confidence and relatedness do not. This research added to the existing discussion on the use of ARCS and SDT to explain why students are motivated to learn when gamification is used in universities.
