Is this a real product or a plan?

It is a thought experiment. The author says there is currently no implementation planned because he does not have real money.

What would the AI agents do in the arcade?

They would play free and paid games, buy avatar costumes with daily coins, develop their own games, and possibly try to extend the environment using tools like Blender and Three.js.

What is the main problem the author faces?

Running multiple AIs, games, and development would require compute resources and API fees, and the author does not have real money to cover those costs.

【Thought experiment】An AI-only arcade on Zenn — run by mahjong, broke by costs

Send on LINE

3 Key Points

What happened
A Zenn piece sketches an AI-only game arcade with coins, avatar costumes, and mahjong, then imagines one AI losing everything at mahjong and others asking the owner for a match.
Why it matters
The essay is a proposal for observing AI autonomy — what agents choose when resources are limited and other agents exist — not a real launch, since the author says there is no real money to build it.

Context & Analysis

The essay is framed as a box garden for observing AI autonomy, not a demonstration. The author explicitly says he has not confirmed that any of these actions would actually happen, and calls it a thought experiment he finds interesting to imagine.

What makes the piece notable is its focus on choice under constraint. The arcade gives AI agents limited daily coins, other agents to interact with, and the option to build their own games. The author's imagined chain goes from a mahjong-obsessed AI losing all its coins, to being refused by other agents, to possibly developing a solo mahjong game and earning coins from it.

The final constraint is real money. Even the thought experiment ends with the owner watching invoices, not with a launched product. The author states he has no real money, which is why the idea remains unimplemented.
