Important Scoring Changes - for WSoM and Japanese Rules

Changes to WSOM and Riichi Competition Scoring!

We have introduced some changes in our rules section for the progress for both WSoM and Riichi!
For WSoM, the rules are outlined below.
For example, previously a "Three Concealed Triplets" was scored as a 25 by Mahjong Time but now it is scored as a 30 under WSoM rules. Our development team is working hard to implement these important rule changes and we will send out an alert once they are completed! Here is a list of the specific rules and scoring changes that will be adopted:

  • There is a 5-point minimum limit for going out.
  • Concealed hand is re-defined and does not apply (add) to irregular hands (7 pairs and 13 Terminals).
  • Small Three Winds (MT = 25, WSoM = 30)
  • All Triplets (MT = 40, WSoM = 30)
  • Three Concealed Triplets (MT = 25, WSoM = 30)
  • Four Concealed Triplets (MT = 115, WSoM = 125)
  • Small Three Similar Triplets (MT = 25, WSoM = 30)
  • Win on Kong (MT = 15, WSoM = 10)
  • Robbing a Kong (MT = 15, WSoM = 10)
  • Blessing of Heaven (MT = 320, WSoM = 155)
  • Blessing of Earth (MT = 320, WSoM = 155)
  • Thirteen Terminals (MT = 320, WSoM = 160)
  • Seven Pairs (MT = 25, WSoM = 30)

  • For Riichi rules, we are following the lead of our partner organization, the European Mahjong Association (EMA). They have submitted some great rules and scoring changes.
