Scoring

Scores for patterns based on Chows

In the default European Classical rule preset no additional points are paid for patterns based on Chow (except for the Chow hand, which is listed in Scores for patterns based on the whole hand). In some rules the winner (and losers, as well, if enabled by the rules) receives bonus for the following patterns:
