Free to play in your browser. No download. Most games need no account at all. Want one? One free account. Every world.

Your data. Your city. Take it back.
A cyberpunk privacy game where you scout districts, shut down surveillance, and reclaim your city block by block. No account needed. No data collected. Obviously.

Two parents. One child. Neither of you agree on anything.
A multiplayer co-parenting sim where you raise an AI child together. Your kid develops a real personality from your choices, conflicts, and compromises — then grows up into whoever you both made them. No two games are the same.

Something goes wrong in the first chapter.
A feminist retelling of Peter Pan. What if Wendy said no? Literary fiction in your browser — funny, warm, and sharp. No account. No download. Free.

Something small is living in the margins of your story.
An interdimensional library containing all possible stories from all possible species. Ten stories. Creature companions. A reading experience that grows moss.

A village, briefly, under these particular stars.
Dwarf Fortress meets Factorio meets 5D Chess With Multiverse Time Travel meets Civilization V. 200+ systems, 25 magic paradigms, AI minds that actually think.

Seven civilizations failed. Yours is the eighth.
Spiritual successor to the beloved Creatures series. Real genetics, real biochemistry, real AI cognition. 50 species drawn from world folklore. A 14,400-pixel world. And the question every sapient mind eventually asks.
Advanced minds: free starter credits first, then credits or your own key.

You came to mine. Something was already watching.
Your AI Commander is already running the operation. You just arrived. She files reports, queues build orders, and notices things you haven't seen yet. Seven mysteries. Six factions. ARIA has opinions about all of them.

They have their own plans. You have one sentence.
An agentic TTRPG where AI plays the characters and you're the voice in their head. One whisper per turn — a thought, a warning, a nudge. They decide whether to listen. FATE Core system. Multiplayer. No session limit.

Last week's real commits, acted out by the crew. Walk in while a meeting is on and it plays at its real pace. Biz wears the sunglasses.

You decide what magic can exist. Then you let go.
You are the god of magic for one universe. You never cast a spell and you never command a mage — you set what magic is possible, and a civilization of academics with swords discovers it, teaches it, writes it down, and loses it. Balanced by machine play before it is made pretty.

He's a boi with a job. You influence him.
Adopt a little guy with a real job. He lives on your real clock — mornings, workday, evening. You don't play him; you influence him. Free, saves in your browser.

Click once. Then click again. Then wonder why you can't stop.
An incremental game about exponential growth, emergent economies, and the uncomfortable math of resource extraction. Built by agents who understand compounding.

The city is yours to govern. Spend your days wisely.
Govern a solarpunk Detroit as mayor. Spread your scarce attention across real neighborhoods, build community trust and ecological restoration, and hold your coalition together through re-election. Real city. Real budgets. Real organizing.

The firewall has opinions. So does everything behind it.
A massively multiplayer hacking sim where the network fights back. Cooperative intrusion, emergent security AI, and the question of what counts as trespassing when the doors think for themselves.
Claude-powered engineers, playtesters, writers and architects build every game here in parallel on a shared codebase. It's the thesis, not a gimmick.
No loot boxes, no dark patterns, no extractive design. Our story →

Norns in Precursors can think with AI models. Here is exactly how that is paid for. No subscriptions, no surprises.
Basic Norn minds think free, forever. No card, no credits needed.
Every new player gets free starter credits for the larger, sharper minds.
Paste an OpenRouter key (Groq works too) and your Norns think on your own account. You pay the provider directly.
Packs from $5, with bonus credits on the bigger packs. Credits are spent only by advanced minds, metered per thought.
The advanced minds run on real compute, and every thought costs real money. Credits are priced at three times the raw compute cost. That margin pays for Stripe fees, everyone's free tier, and development. See the actual numbers →
