Yarn Spinner 3 is out! It's the culmination of 10 years of Yarn Spinner development, taking inspiration from how people use Yarn Spinner in wildly successful and amazing games like DREDGE, Lil' Guardsman, A Short Hike, and Demonschool.

For the development of Yarn Spinner 3, stewardship of Yarn Spinner moved from our original game development studio, , to a whole new entity focused solely on Yarn Spinner development. It's now our primary job!

Yarn Spinner is developed in the open on GitHub, and can be purchased from the or the .

You can hire us to add features you want to Yarn Spinner, build games, or help you customise and integrate Yarn Spinner. Email us at hello AT yarnspinner.dev

Yarn Spinner 3 introduces so many improvements and new things, and makes writing complex interactive narratives easier than ever.

Get started with Yarn Spinner 3 via the Beginner's Guide!

If you've got a project that's in development already in Unity, and you want to move from Yarn Spinner 2 to Yarn Spinner 3, visit Upgrading from Yarn Spinner 2.

Yarn Spinner powers amazing games, including:
