Here's my GraphQL game! https://graphql-of-thrones.herokuapp.com/
I was learning GraphQL myself (through http://howtographql.com/, it's great) and found myself pretty lost in the tooling and serverside code when it still hadn't been established clearly to me what GraphQL -is-.
I am a big admirer of educational games like vim-adventures.com, flexboxfroggy.com and flexboxdefense.com to progressively learn something so I decided to do something similar for my bootcamp capstone. The point I wanted to get across is GraphQL is such a universal idea that you can literally envision Game of Thrones characters scribbling queries on parchment and that would still be valid GraphQL.
Shoutouts are due to UnderExpress.com for the landing page components which made Show HN a few days ago and Codecademy for a proven UI I could shamelessly steal from (with styled-components). More code details written up here: http://www.swyx.io/graphql-of-thrones/
A little nervous since this was put together in a week with a lot of spit and glue but hoping it might help someone out there get to grips with GraphQL.
