GRIDX is a free browser arcade game inspired by Geometry Wars, where you fly around a neon sphere fighting waves of geometric enemies. You pick up weapons, use a special attack called NOVA, survive a mini-boss, and eventually face a fast-paced final boss. There is a global leaderboard where players can register their scores with a short comment. The game can be played instantly at its GitHub Pages link, with no install, no ads, and no monetization. What makes this project unusual is how it was made. According to the README, it was built almost entirely by a chain of AI systems working together, guided by one person whose son helped playtest it. One AI system, described as JARVIS Code, coordinated the process. Another AI, GLM 5.2, first built the game as a single large self-contained HTML file. A separate AI, GPT 5.6, then rebuilt that single file back into the organized TypeScript codebase you see in this repository, and Claude reviewed and helped ship the final result. To confirm the two versions actually behave the same way, the project includes a parity test that runs the game's simulation for three different starting seeds across 3,000 steps each and checks that the results match the original within a tiny margin of error. This works because the simulation logic is fully separated from the browser display and uses a seeded random number generator, so it always produces the same outcome given the same seed. To run the project yourself, you install its dependencies with npm, then you can start a development server, build a production version, or build it back into a single self-contained HTML file, plus run its 143 unit tests and the parity check. Controls use the keyboard and mouse, or touch on mobile, with the usual move, aim, fire, boost, and pause actions. The leaderboard is backed by Supabase, a hosted database service, with security rules and an automatic filter to catch inappropriate comments. Contributions are welcome, especially new enemy types, weapons, or gamepad support, as long as changes stay fun, free, and free of ads or tracking. The project explains that Geometry Wars is a trademark of Activision and that GRIDX is an independent, fan-inspired project not affiliated with or endorsed by them. It is released under the Apache-2.0 license.
