GPTGame is an AI-powered platform that simplifies the creation of JavaScript games. It enables users, regardless of their coding knowledge, to generate and play games instantaneously. The service builds on a neural network, possibly featuring the language model GPT, to create games based on the user's brief text description. The usage of the platform is quite straightforward: the user has to describe the basic concept of the game, generate it, and then can play it instantly. The resultant game code can be copied for further use anywhere. Customization options are also available to the users through a variety of predefined templates. The platform is particularly beneficial for educators and game enthusiasts. In addition to simplifying game prototyping, GPTGame could be a useful tool for learning and entertainment. It is able to generate traditionally popular games such as Snake, with the inclusion of AI enemies, as per user descriptions. Moreover, GPTGame supports the recreation of classic games and enables users to add their own twist to these games. To create a new game, a user inputs their game idea and generates their first game instantly.
