ABSTRACT First-year financial accounting students face high content volume and limited access to timely formative feedback, a gap that scalable digital tools could address. This study examines whether voluntary engagement with a fully gamified self-testing app ‘DUGA’ improves exam performance, and which dimensions of engagement matter most. Data were collected across two independent cohorts (N = 1,248) at an open-access European university using a quasi-experimental design. We compare exam performance between voluntary app users, rigorously controlling for prior accounting ability. We decompose engagement into two distinct indicators: intensity (quantity of questions attempted) and accuracy (proportion answered correctly). Results show that voluntary app users significantly outperform non-users. Among users, accuracy is strongly, positively associated with exam performance, whereas intensity alone is not. Accuracy fully mediates the intensity–performance relationship, indicating that it is not engagement volume itself, but the quality of engagement it produces, that drives exam performance. Moreover, intensity and accuracy combine synergistically: students who practise both frequently and accurately achieve greater exam gains than accuracy would predict independently. These findings help explain mixed evidence in prior gamification research by distinguishing engagement quality from engagement quantity and offer practical guidance for accounting educators on the design and implementation of gamified self-testing tools.
