Hydropolis is an abstract city-building game using the components of the game Waterworks. The "city" starts with one card in the center of the table. Each turn, you play a card from your hand, score points based on its location relative to other cards, add that play's score to your cumulative score, and then draw a card. One by one, the table is filled with a contorted maze of pipes. The game ends when all players pass or when somebody reaches a set amount of points. and the player with the highest running score wins. But if you earn three Golden Wrenches first, you win automatically! Complete rules and revision history is available at: http://ceruleansgames.tripod.com/hydropolis.htm
