Inspired by Guess Who, Guess Whorl is a competitive card game in which players take turns asking questions about identifying features. The goal is to deduce the identity of a mystery British freshwater snail species using the process of elimination, with questions such as; “Does this snail have a pointy shell?” or “Is this snail’s shell striped?”

Guess Whorl was designed to be used as a fun teaching tool. Players can learn about the differences between types of British pond snails and how to deduce and describe those differences like a taxonomist.
