Welcome to mining city. Any dream will come true once you rise to great fame in this city. Those who dream their fortune will proceed without any doubt even if they conduct illegal business. As we say, “Time is money”; time, money, resources, and laborers are all finite things. Don’t forget, everything has its limit. If your way of thinking is like “Next time I’ll try, but it’s OK now” it will prove to be a serious handicap in this city. Your resources will be mined out if you hesitate too long or are not vigilant enough.
Your mission is to acquire the most fame (points) by spending time (action points) in your own turn. Hire laborers (cards) at the facilities on the game board and get their support for your mining business or benefit from their special expertise. Don’t hesitate to have the bank close down or a mine to be mined out in order to hamper the other players.
