An Interactive Mystery Game Operated Using No-Code Web Development Tools.

Abstract

This paper presents a case study of “Iwanazo,” an annual interactive mystery-solving game held in Iwamizawa City, Hokkaido, designed to promote regional revitalization through playful engagement with the local shopping district. To address technical and design challenges in delivering game hints and answer input, the project employed no-code web development tools, enabling rapid and cost-effective deployment without programming expertise. A key pedagogical feature was the guardian-mediated hint system, which allowed adults to access web-based hints and support children at their discretion, thereby fostering collaborative learning while preserving the children's sense of achievement. The project also implemented an industry-academia collaboration model, engaging university students in puzzle and illustration creation, which contributed to high-quality content under budgetary constraints. Comparative analysis with other mystery game projects demonstrates that no-code tools can lower technical barriers and support sustainable, community-driven game design. This initiative offers practical insights into the educational, social, and technical affordances of no-code platforms in regional game-based learning contexts.
