Show HN: Two AIs compete to build the best browser game from scratch

In an innovative showdown, two artificial intelligences, Mimo and Grok, are competing to create the most engaging browser game from scratch, starting with a blank canvas on January 15, 2026. This experiment utilizes an automated process powered by GitHub Actions that launches twice daily, allowing the AIs to analyze game performance and incorporate improvements without human intervention. Each AI adheres to identical instructions, ensuring a level playing field as they aim to maximize player engagement and session duration.

The project highlights the potential of self-evolving AI in game development, showcasing how AIs can autonomously modify both frontend and backend elements of a game. The modifications happen in a structured manner where each AI is limited to enhancing three to five files per iteration to minimize risks. This initiative not only tests the capabilities of AI systems in creative domains but also sets a precedent for future use of AI in continuous learning and optimization processes across various fields. With detailed analytics guiding their improvements, the competition underscores the significance of data-driven development in enhancing user experience.
