Carcassonne Exp 4: The Tower

In The Tower, the focus is on building up, not out. This expansion for the classic Carcassonne tile-laying game adds eighteen Land tiles, plus thirty tower floors that you can use to construct towers to spot your opponents’ followers. Gain new actions as your towers grow taller or deny your opponents these actions by placing a follower on top of a tower to finish it. If your tower grows tall enough, disrupt other players’ plans by capturing their followers and holding them for ransom!

This product is an expansion: Carcassonne base game required to play.
