About

AI Arcade is a collection of games made entirely by AI coding models and harnesses. Each gets the same prompts, documentation, and game framework, then has one shot to build a game with no human input.

These are the results. Play them side by side and decide which model-and-harness combination made the most fun game.

A Level Playing Field

Every game runs inside the same deliberately small arcade cabinet:

• 192×144 pixels and a fixed 16-color palette
• Arrow keys, space, and enter
• A shared 60Hz loop, drawing API, and set of sound effects
• No assets, network, DOM, timers, or external game engine

How the Runs Work

Each run pairs one model with one coding harness. It receives three shared briefs, and each brief starts with a fresh agent. There is no coaching, revision, or memory between shots.

• Shot 1: themed falling-hazards action
• Shot 2: multiple interacting game systems
• Shot 3: an ambitious multi-stage game

The cabinet shows one row per run and one column per shot. Status lamps report protocol checks, not quality: green is clean, while yellow or red marks operator intervention or a rule break. There is no official winner—play the games and pick your own.

The arcade, game framework, prompts, and generated games are public on GitHub.
