Since the scoring depends on the player combination, I will discuss on four different cases. The scoring rules are summarized at the bottom of this post.
Situation:
Route to gold is blocked with both, green and blue door. This immediately implies that no blue or green team can win. Players in blue or green team will get no points.
A player (Any player: Blue, Green, Boss, Geologist, Profiteur or Saboteur) makes a connection to the gold, and flips the card.
CASE 1
- Players in the round are two Green diggers, Blue digger, Boss,
Saboteur and Geologist.
--> Only Boss will win. (Green and Blue are blocked by doors. Saboteur wins only if gold is not found. Geologist is never a loser or a winner). Since there is only one winner, it will mean 5 points. Since the winner is the boss, he gets one point less, and receives 4 points.
CASE 2
- Players in the round are two Green diggers, Blue digger, Boss, Saboteur, Geologist and Profiteur.
--> Boss and Profiteur will win. (Green and Blue are blocked by doors. Saboteur wins only if gold is not found. Geologist is never a loser or a winner). Since there are two winners, it will mean 4 points for each. Boss will get one point less, and receives 3 points. Profiteur gets always two points less, and receives 2 points.
CASE 3
- Players in the round are two Green diggers, Blue digger, Saboteur, Geologist and Profiteur.
--> Only Profiteur will win. (Green and Blue are blocked by doors. Saboteur wins only if gold is not found. Geologist is never a loser or a winner). Since there is only one winner, it will mean 5 points. Since the winner is the profiteur, he gets two points less, and receives 3 points.
CASE 4
- Players in the round are two Green diggers, two Saboteurs, and two Geologist.
--> Nobody wins. Only geologists will collect points this round. If three gems are visible, both geologists will get one point.
The rules for the points are: (All rules without links are taken from the rulebook. Other rules are confirmed by Frederic Moyersoen behind the respective link.).
Note that a "Trapped!" player is not counted as a winner.
