Why This Arcade Exists
This arcade is a playground for testing how AI tools actually behave in the real world.
I build and rebuild the same games using different AI models, agents, and hosting approaches to see what changes over time. Games are ideal for this: the rules are clear, the outcomes are visible, and there's nowhere for bad decisions to hide.
Each project ends as a simple, static experience that's easy to evaluate:
OK. Good. Or Great.
What matters isn't the game itself—it's what it reveals about agent reasoning, context management, self-correction, and how quickly these systems are improving.
Play a game. Try to beat the dog.
Then come back in a few months and see what's changed.
Open Source
Every game in Coop's Arcade is free, ad-free, and open source. Want to build your own version? Fork a repo and make it yours.
