Diferencio, on explique et on joue

About Diferencio, from BoardGameGeek:

You are the souls of the world of Diferencio. As the Architect, change the world while the dreamers are asleep; as a Dreamer be the fastest to spot the differences introduced by the Architect. In Diferencio, a player will change a card while the others have their eyes closed. Once it's done, players have to find the card changed to win it. If a player spot a card which has not been changed, this player can't do another purpose. If nobody find the card changed, the one who change it win it. When a player won 3 cards, the second phase start. The active player can change between 1 and 3 cards (without telling how many have been changed). Players who spot a wrong card will loose one of theirs. Game ends when a player score 6 points.
