Welcome to COBA-cc!

COBA is the Conventional Online Buzzer Application. It was written originally in March 2020 during the first wave of the COVID-19 pandemic to enable the Quiz Bowl community to continue to hang out and play games!

COBA-cc is a complete redesign of the original COBA formula, with the aim of making it work for large numbers of users around the world. The "cc" can alternatively mean "Carbon Copy", "Cloud-Compute", or "Completely Crazy" depending on how you look at it. I'm excited to bring it to you since I feel it represents a major breakthrough for online quiz bowl!
