We need an ambulance! Call the police! The building is on fire! A pipe is broken and the street is flooded. There is a blackout. The phone is dead. When will that letter arrive? As the director-general of a public service department, you are responsible for sending service vehicles to the places where their help is required, but in a city without street signs, this might be close to impossible. Fortunately, the local government has launched a street addressing program, and as street signs are placed all around the city, giving directions will become easier. Players collaborate developing the street addressing program, and compete to get the highest score by being the best at giving and following directions through the city.
