Things on Strings is fully cooperative. Starting with a group of four Things, the Knower secretly creates a rule that splits the grouping in half.
The rest of the players, known as Finders, work together to put new Things on the flowchart. If they're right, the card stays. If they're wrong, the card gets discarded. Can you play all of the cards before your allowed discards run out?
Every group of four gets split, so you'll have cascading rules. Does this start with a B? Yes? Is it edible? No? Okay, does it grow outside?
Keep playing cards in their correct spaces to win. You'll be surprised at how well you'll be able to deduce the flowchart's rules!
