All players are factory managers who select and install machines in their factory.
They try connect all machine input and output pipes to the right reservoirs or to other machines, to build the most profitable configuration.
A new machine brings revenue. Other thing you build (reservoirs and connectors (pipelines)) cost 1K money each.
In each game round players may select one machine (from a number of machines equal to the number of players). Simultaneous. So players try to quickly oversee possible connections. But by choosing too quick, you risk taking a machine which doesn't fit well ... When fitting in a machine, a key tactic is to keep the most and best options for connecting future machines!
After 8 rounds the player with the most money wins.
