When can you stop passing during the Charleston in Mah Jongg?

The Charleston is composed of 3 parts:

  • The First Charleston, consisting of three passes which are compulsory - passing to the right, across and to the left. Any player can stop the passing after the First Charleston and is not required to give a reason.
  • The Second Charleston is optional and also consists of three passes - to the left, across and to the right.
  • The third part of the Charleston is the Optional Pass - 0,1, 2 or 3 tiles may be passed to the player seated on the opposite side of the table - the number of tiles exchanged is dictated by the player requesting the fewer number of tiles.

Although the First Charleston is compulsory, there is one exception. If East draws a Mah Jongg hand, the Charleston is waived and East wins. This is called a Heavenly Hand.
