''Power Grid'' is the English-language edition of the multiplayer German-style board game ''Funkenschlag'' (in its second incarnation) designed by Friedemann Friese. Power Grid is published by Rio Grande Games. In the game, each player represents a company that owns power plants and tries to supply electricity to cities. Over the course of the game, the players will bid on power plants and buy resources to produce electricity to provide power to the growing number of cities in their expanding network. ==Game play== The game comes with a double-sided board with a map of the United States of America on one side and Germany on the other. Each map consists of six regions featuring cities with connections of varying costs between them. The number of regions used is based on the number of players. Map design itself is a key feature in the strategy of game play as some areas of the map feature generally higher connection costs compared to other areas of the map. The game is played in rounds, with each round consisting of 5 phases: #Determining player order #Auction power plants #Buying resources #Building #Bureaucracy The game ends after one player builds a fixed number of cities. The winner is the player who can supply electricity to the most cities with his network. Tie breakers are who has the most money, then the most cities. ;Phase 1— Determining Turn Order: Turn order is rearranged each turn according to the number of cities each player has connected. The player with more connections is placed before a player with fewer connections and continues ending with the player with the fewest cities playing last. When players own the same number of cities, a player with the higher value plant is placed before a player with a lower value plant. (Exception: Turn order is determined randomly at the beginning of the game, and then rearranged after power plants are purchased per the normal rules). ;Phase 2— Auction Power Plants: Turn order determines who begins the bidding on power plants. The first player begins and may choose to pass rather than bid on a chosen plant, in which case they forfeit the chance to bid on any power plants on a given round. An initial bid must be equal to or higher than the value of an available power plant. After the initial bid, players take turns bidding in clockwise order until every player has passed on a current bid. Once a plant is purchased, a new one is drawn from the deck to replace it, with the available power plants re-arranged in numerical order according to their value. The player with the highest priority turn order (which may still be the first player) then has the option to bid on an available plant. Phase 2 ends when every player has either purchased a plant or passed on their opportunity to bid on a plant. Most power plants require one or a combination of resources: coal, oil, garbage (see waste to energy) and uranium, in order to supply electricity. Wind turbines and nuclear fusion plants do not require resources. ;Phase 3— Buying Resources: In reverse turn order, players can buy resources for their plants. Players may only purchases resources they can use, and each plant may only hold twice the number of resources it needs to run. Thus a plant that uses two oil may hold up to four oil. As resources are purchased, they become more expensive, thus the person who is last in turn order can buy resources at the cheapest prices for that round. ;Phase 4— Building: In reverse turn order, players may build into cities. In the first round, a player may choose to build into any city that is not already occupied. A player may continue to expand by paying the cost to build into the desired city slot plus the value of all connections to that city from an already occupied city. No player may build into more than one slot in a city. Slot one costs 10'Elektros' and is the only slot available during Step 1. During Step 2, the second slot is available at a cost of 15 Elektros, and in Step 3, the final slot is available at a cost of 20 Elektros. ;Phase 5— Bureaucracy: During this phase, players expend resources to power their cities and earn more income (Elektros) based on the number of cities they power. Resources available to be purchased are replenished at a rate based on the number of players in the game as well as the current Step. Finally the highest value power plant is placed at the bottom of the draw deck (this changes in Step 3). The game is further divided into 3 "steps". In Step One, 8 power plants are visible to players arranged into two rows of four based on their numerical value ranking from lowest to highest. The first row of the lowest numbered plants is available to be bid on by players. In step one, only the first slot of a city may be built into. Step Two is triggered when any player builds a set number of cities determined by the number of players in the game. In Step Two the lowest level plant is removed (this is only performed once). In addition, the second city slot becomes available for players to build into. Finally, the resource replenishment rate is changed. Step Three is triggered when the Step Three card comes up in the power plant deck. The Step Three card is initially placed at the bottom of the power plant deck. In Step 3, again, the lowest level plant is removed and a new plant is now drawn to replace it. The available power plant pool now consists of 6 power plants that are all available to be bid on. The remaining power plant deck is shuffled to make a new draw deck. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「power grid」の詳細全文を読む スポンサード リンク
