About this project

Gamebook Engine is an open-source iOS application for authoring and playing gamebooks, a form of interactive fiction where readers make choices that affect the story. It runs on iPhone and iPad and supports importing existing gamebooks, creating new gamebooks directly on the device, and exporting work to non-proprietary JSON .gbook files. A companion web player can open shared .gbook files in any modern browser. The project includes an Xcode project for building from source, an App Store release for iOS 15.6 or later, a TestFlight beta, and a wiki. The README also lists an analyzer for detecting unreachable pages or dead ends as not yet implemented.
