Duos Sport i baśnie - przebieg gry

About DUOS, from BoardGameGeek:

Twelve pictures, and four pairs to choose. Oh, this pair is obvious...or is it? How will the other players think? Can you predict? In DUOS, available in editions that feature either things and animals or sports and fairy tales, you're presented with twelve cards in one of the categories and challenged to create four pairs from eight of those cards. If other players make the same pairs as you, they score! Each category includes more than one hundred images.
