  Purpose - The purpose of this study is to develop a game-based mobile
application to help learners practice mathematical patterns and structures.
  Method - The study followed a mixed-method research design and prototyping
methodology to guide the study in developing the mobile application. An
instrument based on the Octalysis framework was developed as an evaluation tool
for the study.
  Results - The study developed a mobile application based on the Octalysis
framework. The application has fully achieved all its intended features based
on the rating provided by the students and IT experts.
  Conclusion - The study successfully developed a mobile learning application
for mathematical patterns and structures. By incorporating GBL principles and
the Octalysis framework, the app achieved its intended features and received
positive evaluations from students and IT experts. This highlights the
potential of the app in promoting mathematical learning.
  Recommendations - This study recommends that the application be further
enhanced to include other topics. Incorporating other game-based principles and
approaches like timed questions and the difficulty level is also worth
pursuing. Actual testing for end-users is also needed to verify the
application's effectiveness.
  Practical Implications - Successful development of a game-based mobile app
for practicing mathematical patterns and structures can transform education
technology by engaging learners and enhancing their experience. This study
provides valuable insights for future researchers developing similar
applications, highlighting the potential to revolutionize traditional
approaches and create an interactive learning environment for improving
mathematical abilities.
