Playables Builder
YouTube Playables Builder is an AI-powered web application from YouTube that lets creators build bite-sized playable games directly on YouTube without any coding experience by using short text, image, or video prompts to describe their ideas and have the system generate a working game prototype. It is powered by Google’s Gemini 3 AI model, which interprets natural language and uploads visual inputs to design gameplay mechanics, visual styles, and interactive elements, producing simple games that can be shared with and played by audiences on YouTube’s mobile apps and website. Playables Builder is currently in closed beta, available to selected creators with approved access in regions like the United States, Canada, Great Britain, and Australia, and requires an active YouTube channel to participate. The games created are lightweight and designed for quick engagement, fitting into YouTube’s existing Playables ecosystem of interactive experiences that run natively.

GameplayKit
GameplayKit is a collection of foundational tools and technologies for building games in iOS, OS X, and tvOS. Building, evolving, and maintaining a sophisticated game requires a well-planned design, GameplayKit provides architectural tools to help you design modular, scalable game architecture with minimal effort. Creating great games also requires deploying complex algorithms to solve the problems underlying common game mechanics, GameplayKit also provides standard implementations of such algorithms, allowing you to spend more time on the features that make your gameplay unique. Because GameplayKit is independent of high-level game engine technologies, you can combine it with any of those technologies to build a complete game, SpriteKit for 2D games, SceneKit for 3D games, or a custom or third-party game engine using Metal or OpenGL ES. For games with less demanding graphics needs, you can even use GameplayKit with UIKit (in iOS or tvOS) or AppKit (in OS X).
