Power Grid: Theme Park is a promotional card that came to life in 2011, when Power Grid fans could trade it for a donation at the 2F‑Spiele booth during the Spiel. The card is not an energy plant, but rather an extra city that the owner can use to expand their distribution network. Once the card lands in a hand, it goes up for auction, and whoever bids the highest wins it, gaining the advantage of a new city without energy costs. The goal remains the same as the base game: buy power plants, generate electricity, connect cities, and power the most consumers. The card adds a layer of surprise and strategy, as the immediate auction forces players to weigh whether it’s worth spending resources now or waiting for better opportunities. For those familiar with the Power Grid flow, the Theme Park card brings a novelty touch without altering the game’s core, keeping the competitiveness and tension that make the title a classic. It’s a fun way to try something new in regular games, especially for groups who enjoy quick twists and testing different bidding tactics.
