1. Core Patterns of the 2468 Section
The 2026 card divides the 2468 section into distinct strategic patterns:
- Monochrome (1-Suit) Evens: Lines utilizing all four even numbers (2, 4, 6, 8) in a single suit. For example:
22 44 666 8888 or 222 4444 666 88.
- 2468 with Matching Dragons: Combining even-numbered melds with their corresponding suit dragons. Dragons easily absorb Jokers, enabling rapid meld calls and lightning-fast Mahjongs.
- Concealed 2468 Hands: High-scoring surprise lines marked with a (C) where players cannot call discards until the final Mahjong tile.
2. The Official Dragon-to-Suit Pairing Law
One of the most frequent beginner blunders in American Mahjong is mismatching dragons with suits in 2468 lines. The official NMJL rules state:
- Green Dragon (Fa): Must match BAMS.
- Red Dragon (Chung): Must match CRAKS.
- White Dragon (Soap): Must match DOTS.
Important Clarification: In the 2468 section, the White Dragon (Soap) is strictly a Dragon for the Dot suit. It can never be counted as a Zero (0).
3. Charleston Passing Rules for Evens
When curating an Evens hand during the Charleston, follow these strategic guidelines:
- Never pass like-suit evens: Avoid passing a 2 and 4 of the same suit together in one Charleston pass, as you hand opponents ready-made meld engines.
- Pairs are sacred: Jokers cannot be placed in 2468 pairs. If you lack natural pairs of 2s or 8s by Charleston Pass 2, strongly consider shifting to an all-Pung/Kong line.
- Connector awareness: Keep 4s and 6s until the second Charleston round—they serve as the vital hinge between 2468 Evens and middle Consecutive Runs.
4. Strategic Pivot Ladders
If your even-numbered tiles are blocked by opponents, execute these tournament pivots:
- Slide to Consecutive Runs: Transition into 3-4-5-6 or 4-5-6-7 if you receive middle odd tiles.
- Slide to Any Like Numbers: If you collect multiple 2s or 8s across all three suits, switch directly into Any Like Numbers.
