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.
Theme Park
The Theme Park needs so much electricity that it is considered a city.
When the Theme Park is drawn, it will be immediately auctioned to the players regardless of the actual phase. After the auction draw an additional power plant card as replacement and place it into the market.
The leading player starts the auction by either passing or bidding at least 10 Elektro. The players continue the auction in clockwise direction until all but one passed.
The highest bidder pays his money and immediately places the Theme Park next to his power plants. The Theme Park does not count as a power plant and can be used additionally to the three (four) power plants.
The player places one of his houses on the city space and moves his house on the scoring track one space ahead. There are no additional building costs (the city space shows 0 Elektro).
