Too Long; Didn't Read
Quiz app was created by Philippe Ozil, a developer at Salesforce, that was unveiled at Dreamforce 2019. The app is actually two apps: a host app installed into a Salesforce org, and a player app built with LWC OSS that runs on Node.js deployed on Heroku. The host app manages the multiple choice quiz questions and answers, real-time quiz sessions, and easy player registration with a URL or QR code. The player app is where anyone with the URL and QR code can join in the fun, no authentication required.
