Viaduct is a 3 dimensional game in which players must stack bridges next to or on top of each other to connect opposite sides of the board. It was published in the Ravensburger Casino Series. In Viaduct, game players try to be the first in building a continuous viaduct across the board. The attractive result is a three-dimensional architectural set-up. An individual combination of strategy, a little luck (dice rolls) and an unusual design combine to give this game its particular attraction. Involvement actually increases as the game continues, the players building up architectural landscapes on several levels.
