Bridges, Castles & Bazaars rules

Bridges, Castles & Bazaars is an expansion for Carcassonne.

How Bridges, Castles & Bazaars changes play

Setup: shuffle the new tiles in; each player takes 3 bridges and 3 castles (2 of each with 5–6 players).
Bridge: after placing a tile, you may place one bridge on it or a touching tile, straight (never diagonal) with both ends in fields. It counts as a road. Put a meeple on it only if it's on the tile you just placed.
Castle: when a tile completes a 2-tile city your meeple is in, you may place a castle there instead of scoring 4. Your meeple goes home; the castle stays. An unscored castle is worth 0.
Castle scoring: it scores the full value of the first feature completed on its 2 tiles or the 2 tiles either side. That feature also scores normally for its own meeples. In field scoring a city with a castle counts 4, not 3.
Bazaar: after placing a bazaar tile and finishing your turn, unless fewer tiles remain than players, reveal 1 tile per player and hold an auction.
Auction: the player on your left picks a tile and opens the bidding in points; others bid higher or pass, clockwise. The picker buys it (paying the top bidder) or sells it (the top bidder pays them; no bids, no payment).
After the auction: the next player without a tile picks; the last takes the final tile free. Then each places theirs in turn, with meeple and scoring; play resumes left of whoever placed the bazaar.

Bridge Details Only one bridge per tile, and it stays until the game ends.
Castles When a tile completes a city of only 2 tiles that your meeple occupies, you may place a castle on it instead of scoring the 4 points.
Castle Details After it scores, the castle's meeple returns and the castle stays. In field scoring a castle is worth 4 points instead of 3 (5 with a pig).
Bazaars After you place a bazaar tile and finish your turn, hold an auction, unless fewer tiles remain than players. Reveal 1 tile per player.
Bazaar Details With a builder, hold the auction before the builder's second tile.
