In Brazil, a great amount of energy is produced by hydroelectricity. Dams are responsible for providing energy to industries, markets, and houses across the country. This electricity is distributed by great networks of transmission. It's a big business that moves billions every year. Elétrica invites you and your friends to take on the role of energy entrepreneurs. During the game, you need to increase the size of the map and construct lines to supply energy to cities. With each new line, you can complete contracts and receive victory points. In more detail, following a set-up phase in which you each place a tile next to the starting spring river tile, on a turn you either (1) reveal and place a new tile or (2) build. The tile-laying works as you might expect, with tiles needing to be adjacent with the elements on each side matching. After placing a tile, you can place a marker on it to reserve it. The game includes five types of constructions — hydroelectric, electrical substation, transmission tower, utility pole, and city — and to build one of them, you use workers on a tile and choose an available construction, following certain limitations on building. A hydroelectric construction must be placed on a tile with water, for example, while a city can't be built next to a transmission tower and three constructions can't be neighbors to one another on a triangle of tiles. When you build a functioning network, you can complete a contract and score points. Two constructions of the same type earns you 2 points, for example, while more complex combinations earn you more. Once the final tile is revealed and placed, the game ends and whoever has the most points becomes an energy magnate!
