Players attempt to build the most successful factory to produce the best products by connecting input and output reservoirs smartly to your machines to build the most profitable factory!
Players each start with a unique empty factory floor with a support pillar in the middle. During the game you purchase machines to place in your factory. Each machine takes 1 to 3 inputs from reservoirs (yellow, blue, red, and brown) and produces one output (of the same colors, or black end products). You must always connect all reservoirs and machines correctly by using the connectors (the pipelines). At the start this is easy, but becomes more puzzling during the game.
Players start with one of each color reservoir, and can sometimes acquire additional reservoirs. On the machine-tiles you see the revenue of each machine. Connecting machines to each other (input on output) makes more advanced products which brings extra profit. But building connectors and reservoirs costs money and you must try to have the most money at the end.
