This free expansion in postcard format appeared on the game fair in Essen 2008. It was distributed free of charge at the booth of the publisher Lookout Games. The card serves as an additional Schedule to the basic game. This extension can be played with the family and the complete version.

It is divided into four fields, each field represents one season. In each round a different field is activated, creating a simulation of the seasons will be implemented very impressive.

At the beginning of the game a guest brand is put on the field of real time and prevailing at the beginning of a turn around a field pushed further. Each season brings a new field of action with you and will be produced once more and sometimes less building materials. On the original board are two additional guest campaign marks the fields marked, are covered in the current round of a special scheme.

The enlargement is really a mini-expansion, but has a significant influence on the game. For the strategists among us it is incredibly difficult to make our tactics, for it is not more regular supplies of raw materials. A small drawback, however, the expansion in two - person game. Reed to build houses is extremely important.

However, it is almost impossible for a player to extend his houses, because in the fall you get an extra reeds, a year later there are no reeds in the spring and is possibly the reed gone again before the player's turn. Otherwise, makes "In the change of seasons" fun and should not be missing in any game of Agricola.
