Abstract
The research examined the effectiveness of an open online learning game platform to host mathematical thinking games for Indie game developers and students interested in developing learning games. The platform features an application program interface which enables game developers to obtain play log data and offers data-analytic functions to monitor how the games are played and received by audiences. The survey results indicated that the platform offered an opportunity for game developers to gain feedback on their prototypes by users and other game developers. It was also indicated that the platform could contribute to enhance the education of future and current game developers.
