Mind Tussle: Design, Implementation, and Performance Evaluation of a Real-Time Gamified Quiz Platform for Collaborative Learning

This paper has presented the architectural design, implementation, and empirical evaluation of Mind Tussle, a real-time gamified quiz platform developed on the MERN stack to address the customization and transparency limitations of existing commercial assessment tools. The system integrates stateless JWT authentication, a modular REST API organized around clearly bounded functional domains, an embedded MongoDB document schema optimized for leaderboard queries, and a React.js SPA delivering a responsive participant experience. Performance testing recorded an average API latency of 57 ms across registration, login, and session-lookup operations. Concurrency trials confirmed that the event-driven Node.js backend correctly maintains per-participant session isolation, accurate score computation, and consistent leaderboard ranking under simultaneous submission loads. These results indicate that Mind Tussle constitutes a technically sound and functionally complete foundation for collaborative digital assessment environments, contributing empirical evidence to a literature historically dominated by motivational outcome studies.
