<![CDATA[This study aims to develop a valid, practical, and effective Roblox-based mathematics educational game to improve junior high school students’ learning motivation. Conducted at SMP Negeri 7 Kota Serang, this Research and Development (R&D) study applied the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The trial involved eighth-grade students, specifically class VIII F for instrument testing and VIII J for product implementation. Instruments included needs questionnaires, interview guides, validation sheets, response questionnaires, and motivation scales. Data were analyzed using descriptive quantitative analysis and N-Gain calculations after completing all ADDIE stages. The results showed that the Math Battle! game obtained feasibility scores of 86% from material experts and 88% from media experts (highly feasible). Product practicality reached 82% from teacher responses and 81% from student responses (highly practical). Product effectiveness was demonstrated by an increase in the average learning motivation score from 34.9 to 47.7, with an N-Gain score of 0.61 (medium category). Thus, this game is feasible as an interactive learning medium to enhance students’ mathematics learning motivation.]]>
