How to build Three Concealed Pungs

• Many pairs at the start: with three or four pairs, don't pung — draw them yourself and the concealed pungs come.
• Don't pung if you can help it: a claimed pung is exposed; keep the pairs and draw.
• Prefer a single or edge wait at the end: with a two-pair wait, a win on a discard turns that pung exposed; if your three concealed pungs are already complete, wait on something else.
• Add All Pungs: make the fourth set a pung too for 22 points and up.
