PACS primarily uses THE BCAPL rule set but there are some exceptions which are outlined HERE and can also be found under “Captains Area” ——> “Official Rule Set” ——> “Click here for PACS Regulations”
Admittedly, there were some changes that were yet to be updated in this rule set. These changes have been made (just this morning) and players should read this updated rule set and familiarize themselves with these PACS rule variations. Thanks for your cooperation.
