Step 4: The Play.
Score with the standard rules of Carcassonne. Non matching sides must be ignored, it simply don't close the road, city, etc. The cloister earn points for the correct-sided tiles (Min 1, Max 9)
The template scores 360 point with the rule of the cathedral multiplying by three the tiles and shields of a closed city, and the Inns doubling the closed roads points, and two-tiled cities scoring 4. If they score 2, the template max is 342 points.
It is the max scoring, but if I'm wrong, please, correct me.
Well, simply have fun. Thanks for your time!
