Three discs representing cat, dog and child are placed on the table. Then an arrow is turned and you have to be the fastest player to put your hand on the right puck and also say the corresponding word. So if the arrow points to the dog, you need to say BAU and put your hand on the dog's disc. If the cat comes out you have to say HELLO and put your hand on the cat. Simple isn't it? What if we told you that there are also bonuses and penances? —description from the designer
