The aim is to enter a keyword that best describe the picture and that the other people will choose too. If both people use the same keyword, you gain points :-) Imagine, you are being shown a picture whose main subject is a monkey, you enter "monkey", the other one "monkey" too. You both earn points. The game host now know that the picture is of a monkey :-D -- Antoine "hashar" Musso
