The three Rock Gold cards allow the players to win extra Gold points.
At the start of each round, after distributing the Miner cards, the player to the right of the Start player chooses and places one Rock gold card face up on any empty spot between the Start card and the Destination cards (but not adjacent to one of these cards). The card remains on that spot till the end of the round.
The first player who manages to establish an uninterrupted path from the Start card to the Rock Gold card, gets the Gold points which are displayed on the card. He/she takes the corresponding Gold point card (Saboteur) or token (Saboteur 2) and places it visible in front of him/her.
A player can secure the Rock gold points in the following 2 ways:
1. Announce during their turn they quit the current round: they play no more cards (but keep their role hidden) and only gain the Rock gold points
2. Continue playing and winning the round till the end : gain the Rock gold points + their share of the Gold for the winning team
In case the player continues playing and his/her team loses, he/she gets no gold at all and must discard the gold points which were acquired by connecting the Rock card. The card or token is put back in the reserve.
