These promo cards are only playable with a copy of Power Grid!
You can use all promo cards together or just the cards you like the most. All cards are compatible.
After preparing the power plant market and the draw pile of power plant cards, the chosen promo cards are shuffled into the pile of power plant cards. Finally the power plant 13 is placed as usual on top of the draw pile.
Industrial Espionage
Thanks to the Industrial Espionage a single player gets informations about the topmost card in the power plant draw stack.
Do NOT shuffle the card Industrial Espionage into the draw stack of power plants. Instead, place the card face up next to the power plant market.
When determining the player order in phase 2 of the second game round, the last player gets the Industrial Espionage without paying for it. This card never leaves the game and only changes ownership between players. The player owning the card is called Spy.
As often as he wishes and at any time the Spy can look at the top card of the draw stack. He knows one more power plant and can use this information for himself during the auctions for power plants. He must not give any direct information to the other players (neither the type of power plant, nor the consumption or number of supplied cities). The other players only get an idea watching the spy during the auctions.
Directly after buying a power plant, the spy must give the Industrial Espionage card to the next best player in player order. If the Spy is first player (the »best« player), he gives the card to the last player.
Example: The Spy is fourth in the player order. After buying a power plant, he gives the Industrial Espionage to the third player in player order.
