SinJim | Social Trivia Game

SinJim is a social, multiplayer trivia game developed and released for the Iranian market in 2016, successfully attracting over 200,000 users in its early growth phase. The game challenges players to answer trivia questions across multiple categories such as history, sports, science, and entertainment, while competing with friends and other players to test their knowledge and climb the leaderboard.

The project was executed end-to-end by ewalk, from initial ideation and product definition to design and implementation, with me as the founder of the team. From a UI/UX perspective, the primary focus was on simplicity, fast interactions, and sustaining a strong sense of competition.

The product included more than 50 unique screens, over 100 custom-designed icons, and a comprehensive component system, resulting in a scalable, cohesive, and engaging user experience that supported long-term user retention and engagement.
