A city with many names over the years and many opinions on those names. Istanbul or Constantinople? sees 1-4 players attempting to sway the streets into lining up with their favorite name for their city. Double sided cards featuring two numbers on each side are dealt out into five lines known as "streets". The value of each card is different depending on it's position and what side is face up on the table. Each turn a player or team of players may choose to flip a card over, swap and rotate cards in two different streets, or switch a card in a street with one in their hand. When the right-side-up numbers in a street sum up to certain values the player may score that street, gaining points equal to the highest card played in the street. Once all streets have been scored the game ends and the player with the highest point total wins. Contents: 18 Poker Cards Folding Box/Rules —description from the publisher
