Check for ship availability depending on class of starport. The notation nD6:m+ should be read as “Roll nD6. The number you roll indicates how many D6 to roll. For each die that shows m+, a ship is available to take passage on.” If the result of the first roll is zero (e.g., if 1D6-3 and you roll a 2), there are no ships available this week. For example, 2D6:3+: Roll 2D6; the result is 6. Now roll 6D6; the results are 3 4 2 5 3 1. Since four of the dice are showing 3 or more (3+), there are four ships available to take passage on.
