Players play as "Finders" and attempt to correctly place "Thing" Cards into a Venn Diagram. Each Ring of the Venn Diagram has special rules. The twist? Only one player, playing as "The Knower," knows the secret rules.
The rules fall into three different categories:
Word: about the spelling or structure of the word,
Attribute: about the physical properties of the object
Context: about the position of use of the object in society.
