Vedo doppio is a pattern recognition game. There are 14 cards with 8 objects and 28 cards with 1 object. The basic rule of Vedo doppio is that, drawing 2 cards with 8 objects, there are exactly 2 objects in common. Whoever spots the 2 objects in common on both cards picks up the correspondent card. There are 5 different ways to play. The first 3 games are related to the basic rule described above, the other 2 games are different and, for example, require memory. —description from the designer
