The rules of Minnesota say the following :
"If you have at least one coal mine, you
may build a rail link from any of the three ‘Chicago’ name boxes. You may
also build to a ‘Chicago’ name box from an adjacent Minnesota location.
You can only use a coal mine industry card if you already have a coal mine
or if you are connected to a ‘Chicago’ name box by rail link."
Can you build in the first round in Chicago with a coal mine industry card, or does this rule also count for the very first building action?
1. You may use a coal mine industry card as your first build.
2. You may also use a coal mine industry card to build in Chicago if you already have a coal mine and/or if you are connected to Chicago by a rail link.
