Mahjong Charleston Cheat Sheet & Strategy Flowchart (PDF)

A crystal-clear, printable 2-page reference sheet designed to sit beside your NMJL card during home games, study groups, and club practice sessions.

Page 1 Overview: The Opening Hand Decision Flowchart

Page 1 organizes the first 30 seconds of the deal into an actionable visual hierarchy:

  • Step 1: Anchor Natural Pairs (★ Crucial): Identify natural pairs in your initial 13 tiles. Jokers can never replace pairs or singles on the NMJL card.
  • Step 2: Cluster Suit & Number Alignment: Categorize your tiles into Evens (2468), Odds (13579), Consecutive Runs (3-4-5-6), or 2026 Year Tiles (2s, 6s, and Soaps).
  • Step 3: Calculate Safe Pass Trios: Identify isolated winds, opposite-suit honors, or orphaned numbers contributing 0 value to your primary hand candidates.

Page 2 Overview: Defensive Withholding & Blind Passing

Page 2 equips you with defensive table awareness to avoid feeding opponents:

  • The "Never Pass" List: Never pass two matching suited tiles or a complete consecutive run (e.g. 4-5-6 Bams) in a single pass.
  • Blind Pass Protocol: Permitted ONLY on Pass 3 (1st Left) and Pass 6 (2nd Right). Never look at blind tiles before passing.
  • Calling "STOP": When you possess 10+ matching tiles or fewer than 3 throwaways after Pass 3, call STOP to protect your advantage.
