This game is based on the inability of the human mind normal people (me for example) to "consider" simultaneously over four head objects. You do not believe me? So so try this game and see! In Pippo there are cats, dogs, pigs, horses and cows. These various animals are all present in five different colors: blue, red, yellow, green and purple. Each tower has a card representing four different animals in four different colors. Your goal will be to identify the missing and the missing color animal THEN to find this individual among the twenty-five cards of animals representing all possibilities. At this time, Pippo ask again a force as you will verbalize the animal (eg yellow dog). Of course the first to successfully won! Easy you say to me, then for the colors is often automatic (it should not be part of the concept of objects), by cons to determine the missing pet you will have to mentally go through the list of these to determine which one is missing and is ... exhausting force. A game that does not look like much but makes you finger your mental limitations of being human (unless you are an alien in disguise ...). A stressful game, nervous and not very long that can be played with the children if allowed time to make sure time!
