Unlike the previous 5 levels, all players score their own points from now on. The required point value for each hound, or for the goal tile, only counts as having been reached once each player has reached or passed it. Only then will you receive and be allowed to place the hounds. It is therefore important that all players score points.
You connect the two cities and then score. Both you and your fellow player score 6 points. Move both the yellow and red on the scoring track forward 6 points each.
