Google has been giving away a game to build games since November

Google’s Area 120, an idea incubator that’s had some hits and misses, has released Game Builder for free. It’s a simple, easy-to-use game that teaches basic logic and code concepts, while giving players the tools to build their own 3D games. It uses a card-based visual language to ease players into programming behaviors and actions, but more ambitious tinkerers can dive into the JavaScript functionality to make their own virtual code cards.

Game Builder has been out on Steam early access as something of a stealth release since November. Area 120 only publicized the game today.
