Flow chart fun!

About Things on Strings, from BoardGameGeek:

You'll cooperatively use logic to compare, contrast, and categorize Things-just like in the first game (Things in Rings). But, instead of a Venn Diagram, the player playing as the Knower comes up with the rules of a cascading flowchart. As more and more Things get added, groups split with new rules. While the flowchart grows, you'll surprise yourself with how well you can follow the logic (or, laugh at yourselves at how lost you truly are). -description from the publisher
