As rock n' roll fans players are collectors of rock items. Rock N' Brock is an auction card game with a fun cooperative mechanic. each round, players bid for a set of 3 items (posters, clothes, musical instruments, ect..), trying to collect several items of the same kind to earn the most victory points at the end. the board is made of 3 row of 2 "slots" (cards) and each player at his turn make an offer and place his bid on a slot of one of the 3 rows. Players can (sometimes are forced to) bid with another player in a cooperative auction in the same row. once players have placed their bids on one slot they can't move to another row but they can increase their bids until everybody stop. then the row with the highest bid win the 3 items and some gold. If the auction was cooperative, the winners share themselves the goods (see rules). The game ends when the deck is empty.
