Carcassonne : Bridges Castles and Bazaars

The eighth expansion for Carcassonne, Brücken, Burgen und Basare (English: Bridges, Castles & Bazaars) allows players three new options while playing:
Bridges may be used to continue a road over a field tile, thereby allowing an incomplete road to technically run into a field segment. They are otherwise treated and scored just like roads.
Castle tokens are placed atop 2-segment cities and allow players a chance to cash-in on the next completed adjacent feature.
Bazaars are a new type of tile that allows players to auction off tiles in exchange for points.
