TwilioQuest, a game developed by Twilio, is designed to teach students coding skills while building their confidence to contribute to open source projects in a fun and engaging way. The game follows a storyline where players, called "Operators," complete missions that correspond to different programming skills or languages, with a specific mission named "Flame of Open Source" to aid in contributing to open source projects. During the GitHub Univers(ity) event, a competition called Operation Univers(ity) encouraged students to play TwilioQuest, resulting in 220 unique participants completing an average of 24 code challenges each, with 160 finishing the "Flame of Open Source" mission. This interactive approach demonstrates that playing games like TwilioQuest can enhance coding skills and confidence, as emphasized by its creator, Kevin Whinnery, and further detailed in his presentation.
