Rani’s Case Files is a narrative-driven match-3 game developed to cater to the unique cultural preferences of Indian gamers. The project was initiated in response to a notable gap in the Indian mobile gaming market, while foreign titles enjoy high engagement, local narratives have been largely overlooked. The hypothesis posited that integrating culturally relevant storytelling into the match-3 format offers an immersive player experience and would significantly boost player engagement and retention. Rani’s Case Files positions itself not just as entertainment but as an interactive storytelling medium. The project refined its core gameplay loop and narrative mechanics through rigorous market research, affinity testing, iterative prototyping, and playtesting. The result is a game that not only delivers an engaging puzzle experience but also resonates deeply with the Indian audience. This success is now reflected in its live presence on the Play Store and App Store, boasting more than 50,000 downloads to date.
