This study aims to test the self-determination theory (Ryan & Deci, 2000) that relates the type of gamification activities based on the student hybrid player type to the engagement of undergraduate students at a Saudi Arabia public university. By measuring the influence of the type of gamification and the hybrid player types on the student's engagement. And the interaction effects exist when the influence on the type of gamification depends on the hybrid player types' using an experimental 2X4 factorial design to answer the research questions: 1. What is the impact of tailored gamification activities on students' engagement? 2. What is the relationship between students' hybrid player types and their engagement? 3. What is the interaction between tailored gamification activities and students' hybrid player types? One hundred forty-one undergraduate students registered at an online course in a Saudi Arabia public university female section participated by using the gamified activities in Moodle learning management system for ten weeks. Data collected using Moodle logs and analyzed by 2X4 two-way between-subjects factorial MANOVA test with the hybrid player type (Philanthropist, Socializer, Free Spirit, Achiever) and gamification activities (traditional, tailored) as the factors and points, time, and clicks as dependent variables. The finding agreed with the literature on the positive effect of tailored gamification on undergraduate students' engagement. However, more investigation is needed to understand how students' player type affects their engagement, the Gamification Hexad user type interaction with the tailoring of game elements, and if there is other mediated variable that affects the customization process from beneficial to overwhelming.
