Cloister Clustering Rule
Cloisters often ‘clump-up’ during a game. This is a variant rule to discourage playing Cloisters next to each other.
====================
A cloister is completed when it is surrounded by eight tiles. The player who has a monk in the cloister
immediately scores 1 point for every tile surrounding the Cloister and 1 for the Cloister itself. However if there is another cloister nearby, do not score any points for the other cloister or land tiles that surround it.
Example
If A places the final tile surrounding his Cloister he would score 5 points for the tiles that do not surround or are not another player's cloister.
