Game Schema - ARC-AGI-3 Docs

ARC-AGI-3 games are turn-based environments where agents interact with 2D grids through a standardized action interface. Each game maintains state through discrete action-response cycles.

Each response contains one or more 2D frame arrays plus game-state metadata.
Agents respond with an action to interact with the game.

Game States

State	Description
`NOT_PLAYED`	No game has been started
`NOT_FINISHED`	The game is active and awaiting another action
`WIN`	The objective was completed successfully
`GAME_OVER`	The run ended without a win

Grid Structure

Dimensions: Maximum 64x64 grid size
Cell Values: Integer values 0-15 representing different states/colors
Coordinate System: (0,0) at top-left, (x,y) format

Game ID Format

Game IDs are formatted as <game_name>-<version>. game_names are stable, but version may change as games update.

Game Available Actions

Each game provides an explicit set of available actions. The actions available vary per game and are stated explicitly so your agent knows what it can do. To learn about the standardized action interface, see the Actions page. To see how to retrieve a game’s available actions programmatically, see List Available Actions.
