Flex is a skills prediction engine that can recognize the skills and attributes people display when they play popular video games. These are classified as a "Flex" or a "Flex Verified Skill" and they can be used in credentialing or assessment.

For example, players of the popular video game Among Us in 2018 used communications skills to identify one another while evading detection for themselves themselves. Achieving a select milestone or uncommon performance metric in that game may yield the Flex Verified Skill "Uncommon Communications Skills."
