Players move their workers around the board (which is composed of variable groups of hexes) building houses along the banks of two rivers. Each turn certain hexes along the river pay out, either in money (which you use to build houses) or lumber (used to make dams). The first player to construct all five of their buildings (four houses and one hacienda) or a hacienda and three houses that are all on a riverbank, wins. Players build dams to change the flow of the rivers.
Two new expansion maps for Power Grid: Brazil on one side and Spain & Portugal on the other.
In Brazil, power providers prefer biogas for the production of electricity. Thus, players should consider the garbage power plants as biogas-fired power plants and the garbage resources as biogas tanks when playing with the Brazil maps. The fight for scarce resources is intense and will keep the players focused during the game!
In Spain & Portugal, the interests of power production develop in two completely opposite directions: Uranium will be much more important than in other games, however not at the beginning. The resource market will not get any new uranium at all during »Step 1«, but the supplies of uranium increase rapidly in »Step 2«. On the other hand, and at the same time, three large wind-power plants come onto the market. This clash of interests is intended!
The expansion includes a "Collector's Box" - a standard sized Power Grid box with space for the other expansion maps that have been released up to 2009.
