This paper presents the development of an internet game room that enables playing chess and tic-tac-toe via network sockets. The primary goal is to gain practical knowledge of using Angular for the frontend and Java Spring Boot for the backend, and the integration of PostgreSQL and MongoDB databases. The work began with an overview of the technologies used in the project, including Java, Angular, Node.js, PostgreSQL, MongoDB, and tools such as DBeaver, Studio 3T, IntelliJ IDEA, Postman, GitHub and Git Extensions. In the system architecture chapter, key concepts such as sockets, CRUD operations, and server architecture including controllers, services, and repositories are explained. Also, the database is described in detail, together with a diagram and a description of the tables. The application implementation covers the security aspects of the server using Spring Security and JWT for authentication and authorization. Key functionalities such as user registration and login are also described in detail. The conclusion of the paper summarizes the results achieved and suggests directions for future development of the application, including possible additional games and improvements to the user experience. Keywords: internet game room, network sockets, Angular, Spring Boot, PostgreSQL, MongoDB, chess, tic-tac-toe
