The research paper \"QUIZTRIV: A Knowledge Showdown! explains the creation and assessment of an Android mobile educational quiz game intended to improve learning through amusement. It is designed to offer a dynamic quiz experience that covers the subjects of History, Entertainment, Technology, Geography, Art, Science, and General Culture. The initiative highlights the idea of \"learning through play,\" where users can reinforce cognitive abilities in a fun setting, and is informed by Piaget\'s Cognitive Development Theory. The variety of tests will enhance users\' knowledge across a diverse range of topics while enjoying the game. This study used a purposive sampling technique for selecting evaluators from the Eulogio \"Amang\" Rodriguez Institute of Science and Technology (EARIST) Cavite Campus. The research employed an Agile methodology for the research design and ISO 25010 as the evaluation tool for application software. Statistical procedures such as the weighted mean, simple percentage, and chi-square test were used for analysis. The system\'s evaluation results were rated as \"Excellent\" for all criteria of ISO25010. Additionally, results showed no correlation between respondents\' evaluations of the system and their demographic profile, which suggests a consistent user experience. All things considered, QUIZTRIV effectively combines learning and games, proving that mobile applications may be useful resources for enjoyment, critical thinking, and knowledge reinforcement. According to the study\'s findings, educational games like QUIZTRIV can be creative and easily accessible teaching tools, especially when it comes to encouraging students\' cognitive engagement and academic enrichment.
