Carcassonne: Die Kornkreise (The Corn Circles), the seventh official mini-expansion for Carcassonne, consists of six tiles depicting corn circles made from corn stalks. A corn circle tile allows a player to place a second follower on a feature that they have already-claimed or return an already-placed follower back to his supply.
Carcassonne: Die Kornkreise first appeared in Germany as a bonus expansion shrinkwrapped to the Carcassonne base game, and was later available directly from the publisher Hans im Glück. These tiles are included in Carcassonne: Corn Circles, Plague & Tunnels, a English-language compilation by Rio Grande Games of small Carcassonne expansions originally published individually by Hans im Glück.
A second set of six Carcassonne: Die Kornkreise tiles come packaged in six mini-expansions for Carcassonne – one tile per expansion – released by Hans im Glück, 999 Games and Rio Grande Games. These tiles can be used on their own or combined with the tiles from the first Carcassonne: Die Kornkreise expansion.
