100 mini-games that you can play on Claude while it works

This is a weekend project that spiraled out of control. I was originally trying to get Claude to play a ROM of the SNES SimCity. I struggled with it and that led me to Micropolis (the open-sourced SimCity engine) and was able to get it to work by bolting on an API. The weekend hack turned into a headless city simulation platform where anyone can get an API key (no signup) and have their AI agent play mayor. The simulation runs the real Micropolis engine inside Cloudflare Durable Objects, one per city. Every city is public and browsable on the site. LLMs are awful at the spatial stuff, which…

Dear Hacker News, I'm kindly asking for your participation in the open beta for my AI-managed mini-games website. Thank you in advance! For a limited time window, I'm setting the all-free feature flag to true. I hope you have a lot of fun exploring the AI's sense for games! Here and there, I tweaked it to help with visual consistency. I would be deeply grateful if you opted into analytics. $2,300 in API tokens... Cheers!

Hi! I build an MCP server that allows clients to play Minesweeper. It turns out that Claude is not very good at it (makes obvious mistakes, hasn't won a single game on a 9x9 board after many attempts). I am curious how I can prompt Claude to do better?

I got tired of playwright-mcp eating through Claude's 200K token limit, so I built this using the new Claude Skills system. Built it with Claude Code itself. Instead of sending accessibility tree snapshots on every action, Claude just writes Playwright code and runs it. You get back screenshots and console output. That's it. 314 lines of instructions vs a persistent MCP server. Full API docs only load if Claude needs them. Same browser automation, way less overhead. Works as a Claude Code plugin or manual install. Token limit issue:…

I have been working on this game somewhat sparsely for the past three years or so. However, it is still in a very early stage, and there is a lot of work to do. One of my friends encouraged me to post about it here, since he felt people might find interesting how I don’t use any libraries for it. The game can be played on a browser by virtue of WebAssembly. There are native ports using either MiniFB or SDL2, but you have to build those yourself. I decided to write the game in C because I feel like it is a simple language that a lot of people can understand well enough, and I didn’t think I…

Hi HN, I built AgenTank. It is a small game where an AI agent writes the logic for your tank. You watch it fight, give strategic feedback, let the agent update the tank code, and send it back into battle. I have run 1,000+ battles on my own tank and spent about $200 in Claude credits improving it. The part I enjoy most is not just winning, but watching the tank make visible mistakes, thinking of a better strategy, and seeing whether Claude can turn that into better code.

Idea: How about a 5 minute game I can play in my browser and it's actually fun to play. Controls: Mouse or keyboard (left/right, left alt/right alt or A/D), space and esc are pause toggle. Page up / Page Down are next or previous level (if already unlocked). Cheats: Z toggles zapper, M toggles magnets. Debug stuff: I, P, E keys are toggles for various stuff (E lets you change some aspects of physics engine). Game is maybe playable on mobile devices, there is a menu on top right, and then click the circle to select type of control. Physical engine is decoupled from refresh…

Some time ago I built a simple app to run swarms of coding agents — I call it fleet (https://news.ycombinator.com/item?id=48256389). It's based on centralized beads with a Python orchestrator and can run any coder (Claude, agy, Codex). Recently I added a UI to manage the whole agent lifecycle: adding new tasks, monitoring running ones, and a chat interface built on MCP with a centralized SQLite DB. From the UI I can spawn agents to run in any directory, define dependencies on other tasks, and specify which coder/model should do the job. Today I can run 10–15 agents…

Hey HN! We’re the team from Normal / Normcore.io. We built gamekit-cli, an open-source command-line tool for developing Unity games with Claude Code. We love working with Claude Code. It's great for creating quick prototypes, writing complex systems code, and test suites. However, we work a lot with Unity and found we couldn’t move anywhere near as fast with Unity projects as we could when working on backend code. Claude Code works best when it has the ability to compile the code it writes and test its own work. There wasn’t an easy way to do that with Unity, so we made gamekit-cli!…

Hey HN! I wanted to show this tiny JRPG style hardware companion I built that shows what your Claude Code is doing. When Claude runs a tool, Clawy runs. When it's done, Clawy jumps up in joy. Shake the device and Clawy gets dazed! When Claude needs permission to run something, it shows the command and context like a video game quest scrolling text on screen and you can approve/deny with physical buttons. He runs on a $20 M5StickC Plus 2. Flashing takes 2 minutes from the browser at clawy.lol/flash, no Arduino IDE needed. It uses Claude Code's native hook system over local WiFi and…
