Researchers from the CUHK MMLab laboratory have introduced OpenGame — a free, open-source tool capable of creating full-fledged browser games from a simple text description. The project was officially launched in April 2026.
The system is based on a specialized AI model, GameCoder-27B, trained specifically for game development. OpenGame automatically performs the entire project creation cycle: it plans the game structure, writes code, assembles game elements, tests the build, and independently corrects errors.
One of the key features of the project is the Game Skill system. It saves successful project templates and proven error correction methods, allowing the AI to improve the quality of created games over time and more quickly resolve compatibility issues between files and game mechanics.
The developers claim that OpenGame can create a wide variety of game genres — from platformers and action games to quizzes and strategies.
