1. A short course or brief instruction designed to teach you how to do something specific.
Fortnite uses many types of tutorial:
Written tutorials that explain how to do something,
Tutorial videos that show you how to do something,
Template islands that come already built, with corresponding written tutorials that you can follow to deconstruct the island's mechanics, then build your own.
2. Instructional gameplay that teaches a player a specific set of skills, or provides lessons on a specific topic. Research supports the fact that games can be used to increase student participation with increased motivation to learn.
