The game consists of 45 cards with photographs, ten sheets with nine photographs each, one blank sheet with nine squares, a guide, a book with texts that speak about the city, and a bag with numbers. A maximum of ten players can play; once a player matches his or her nine squares on the blank sheet he or she wins the game and must interpret and "read" the city according to the photographs on the sheet. Other players may then read their own cards, leading to an open discussion of the city.

Photographs, which represent different aspects of the city, emphasise health issues like nutrition, HIV/AIDS, smoking, alcohol use, drug use, young mothers, violence, pornography, death, and poverty.

Health, Youth.

Launched in May 2001 at a popular festival, the game has been used in schools and in public spaces, particularly with young people. As of June 2007, the editon is sold out, but organisers expect that another version will be released shortly.
