Enigma is a Jeopardy-like study and quiz tool. The game board is broken down into categories with multiple questions in each category. Enigma is designed for use with Materia, an open-source platform for interactive course content developed by the University of Central Florida.
In a production evironment, Enigma is installed to your Materia instance and is accessed via the Widget Catalog. For development, Enigma is bundled with the Materia Widget Development Kit, which allows for rapid development in a local context using express.js.
Enigma uses the Materia Widget Development Kit for location development. Check out the docs for the MDK to learn more about starting up the local express environment.
Widget installation options are covered in the Installing Widgets section of the Materia Docs.
