"It's World War II and you're an Allied spy, one of the most cunning spies in the business. Your assignment is the most dangerous you have ever undertaken. You must enter the exotic and perilous island of Macao, center of a teeming network of international spies just off the coast of China."
"Once on Macao, you secretly make your way to the legendary Brass Monkey Club, site of the local espionage network and the place where you will make contact with the Master Spy himself, H.E. Rasske. But before you reach the sin-infected Brass Monkey Club, your life and your country's security are endangered many times."

To win the game you need to move around the board, collect at least three Brass Monkey cards, and be the first to land on the Brass Monkey Club at the end of the track by an exact roll of the dice. Fail to make the exact roll and you might find yourself starting from the beginning of the trail again! Minor complications are introduced by the Risk cards, while Subterfuge cards aid you in your clandestine mission.
