A Twilio-enabled music trivia game can be built using Java and Spring Boot to engage attendees and fans before a music festival. The game involves responding to music-related questions, with the goal of correctly answering the most questions to win. To build this game, a new Spring Boot project is created, setting up the necessary dependencies and configurations for MySQL databases. Models are defined for users, questions, games, and real-time data synchronization. Services are implemented to handle business logic, including user creation, game start, adding players, sending questions, receiving answers, and ending the game. A controller is built to handle incoming requests and return responses in a RESTful manner. The code can be tested using Postman, ensuring that it performs as intended.
