This is a question and answer card game about cities around the world. The deck includes 100 cards, and each card has 6 questions with that card's city as the answer. Each card also shows the date the city was founded and its population as of 1889. Former cities like Sparta, Troy and Pompeii have no population shown. When used as an education aid, the teacher may draw cards, ask a question and award it to the player first able to answer correctly. Cards may also be distributed, with players taking turns asking a question: they either give it to the other player answering correctly, or keep it if no other player can answer. In either case, the player with the most cards at the end of the game wins. —user summary
