  1. Replace the game name and the things to generate and compare, then send it to an AI chat or coding tool that can run code.

What it can do

This is a game prompt Simon Willison published on his blog. He used it in an ordinary chat in the Claude phone app to make the small game Tree Appreciator, which is already listed in our AI Games section. The prompt asks for a Three.js game that shows two algorithmically generated trees, with gameplay built around appreciating the differences between them, and asks the model to think hard about making it both fun and beautiful. The author also published the full build transcript, so you can see how the model got there step by step. What sets it apart is that it gives only a theme and the request to be fun and beautiful, leaving the rest to the model, which makes it a good way to see how much a model fills in by itself. Replace the game name and the things to generate and compare, then send it to an AI chat or coding tool that can run code.

Who it is for

Anyone curious how complete a game a model can make from one short brief.

Before you use it

The author used Claude Opus 5.5 in the Claude phone app, and other models will give different results. Your input goes to the AI service you choose, and costs depend on that service. The blog has no reuse licence, so we show only the opening fragment; see the author's post for the full prompt. The finished game can be played on the author's site.
