This article presents a game-based learning model designed for tourists in a smart city. The goal is to increase tourists’ sightseeing experience, tourist spot visitation rates, learning, and satisfaction. The educational game was designed using the advanced web, mobile, IoT, augmented reality, and blockchain technologies. The game aims to guide tourists and test their knowledge about a city. The rewards selected to motivate players’ progress in the game were defined as tokens saved on the blockchain and used to claim prizes. We present the architecture of the proposed system and the business model for the sustainable operation of the proposed system. The proposed approach is expected to contribute to introducing smart tourism services and promoting the general experience of tourists.
