It was designed by Jeroen Doumen and Joris Wiersinga and published by Splotter Spellen in 2001. Its play centers around ownership of valuable networks, replacing the rail networks found in most 18XX games with irrigation canals, shares with parcels of land, companies with kingdoms, trains with irrigation technologies (such as reservoirs and pumps), and presidents with kings. Networks of canals and waterworks generate income by irrigating lands within kingdoms.
