Both games, 18Rhl-Rhineland (18Rhl) and 18LRA-Lower Rhine Area (18LRA) set in the western part of Germany. Most of the rules are the same for both games but they have different elements and therefore, different challenges. In 18Rhl, the crossing of the Rhine and running the Rheingold Express is important for successful play. It is suitable for 3 to 5 players and last between 3 and 4 hours. In 18LRA, the Rhine harbours are a key factor for victory. 2 to 4 player compete in a game that offers a shorter playing time than 18Rhl. Each game has a different map as well as a different set of private companies. The features of the latter give each game its special flavour. There is also a rule for a ‘Short Game’ that can be played within one hour and a 2Player variant.

In the rulebook the section that are valid for both games are on a white background. Rules applying for 18Rhl only have a green background, those specific for 18LRA have a brown one.
