Players build tracks between cities and mines. Each mine corresponds to a single mine card that produces a single type of good, e.g. diamonds, rubies, emeralds. Players build track using their surveyors, claim mines using their agents and operate the mines to produce goods. When their track connects the mine to their base they may ship goods home via transports to earn income. They may also construct passenger routes to gain income. Along the way they hire additional surveyors, agents and transports to increase efficiency.
