The idea behind the COMC Challenges is simple: we have millions of card images, and we're asking the community to provide information from the cards while our identification experts focus on the creation of sets. Challenges are designed to gather data as quickly and efficiently as possible by showing a series of cards and asking simple questions about them. You may access the COMC Challenge home page here.
A video explaining COMC challenges can be found here.
COMC Challenges are launched every Wednesday and Sunday at 4PM PST. They are very popular and are typically quickly completed. We are aware that many more customers would like to participate in the COMC Challenges than are currently able. We are working to update this system in the future, but it is a work in progress and we currently have no estimated timeframe for an update.
We are currently awarding $1 of store credit and 100 History Points for every 1,000 points earned.
