How to reach 8 points

Two Melded Kongs is only 4, and because the hand is open Concealed Hand is not available, so you need 4 more. Common ways:

CombinationPoints
Two Melded Kongs + Dragon Pung + Prevalent or Seat Wind8
Two Melded Kongs + All Pungs10
Two Melded Kongs + Two Dragon Pungs10
Two Melded Kongs + Half Flush10

A melded kong gives you an extra draw, but it also shows your hand. Before you kong, know where the 8 points come from: two simple kongs plus chows often stall below 8.
