Rules questions
Answered from the rulebook by Ludoya's rules assistant.
How many Special Plutonium Mine tiles do we set out?
Shuffle all 9 tiles and randomly place a number equal to the number of players on the Mine Offer tile, with their Worker costs face up. Put the 4 Plutonium cubes beside the Uranium cubes (p. 1).
Can I build more than one Special Plutonium Mine, and what does it cost?
You may use the Industrialize action once per game to take a mine from the offer, pay its Worker cost, and place it within one of your networks. If it has an immediate reward, gain it, then place a Worker from the general supply beside the tile to mark ownership (p. 1).
Can I choose Plutonium instead of Uranium when I gain Uranium?
Yes. Whenever you gain Uranium, you may place 1 Plutonium instead on the empty special space of a Special Plutonium Mine; each such mine can store only 1 Plutonium (p. 1).
Is Plutonium different from Uranium when I use it?
Plutonium works like Uranium for game effects, including exchanging it for a Worker and transporting it to a Power Plant. The exception is that Plutonium provides 3 Energy instead of 2 (p. 1).
Do the Special Plutonium Mines all have the same bonus?
No. Their benefits differ: some are immediate, while others trigger after actions such as Recharging, placing a Mine or Turbine, or taking an Industrialize action. Follow the benefit printed for the mine you place (pp. 1–2).
Can I use this expansion with the other Nucleum expansions?
Yes; it is compatible with the base game and all released Nucleum expansions listed in the rules. For a first play, the rules suggest using it with the base game only (p. 1).
