Things in Rings = this did my head in!

About Things in Rings, from BoardGameGeek:

In the center of the table, place the Rings and form a triple Venn diagram. Designate one player to be "The Knower." The Knower knows the different logic rules for each Ring and will facilitate the game. All other players start with a hand of five object cards. Depending on the Ring, the logic rules will be related to different characteristics, like spelling, grammar, physical properties, cultural relevance, or industry. On your turn, place an object card from your hand into the Venn diagram. If it fits that Ring's rules, place another card. If it doesn't fit the rules, "The Knower" moves the card to the right area. The player then draws another card. The point of the game is to get rid of all your cards. Can you figure out the Rings' logic before your opponents? Don't forget, you can play in the overlapping spots of the Venn diagram, or even outside it completely! -description from publisher
