Yesss! is a party game, one in which communication is the key to saving humanity against itself! Professor Emmet BLUE, a brilliant though slightly mad scientist, is sure about this, and he and his students have developed an experiment to increase our mutual comprehension skills: Translating an association of two pictures into one single concept that must be understood by others. Can you be Professor BLUE’s most brilliant disciple? Yesss! Yesss! features two play modes — co-op & versus — and in both you're trying to make others guess a pair of objects by giving them only a single word as a clue. In the versus mode, you win by having the most brain tokens; in the co-op mode, you're trying to identify as many pairs as possible in three minutes.
