Abstract
A gamified challenge is presented to a user communicating with a website when the user is suspected of being a bot. The gamified challenge consists of a dynamic sequence of animated geometric objects displayed in an order that the user has to interact with within an allotted amount of time. The complexity of the gamified challenge increases when the challenge is failed and when features extracted from the user session indicate a high level of suspicion that the gamified challenge is performed by a non-human user.
