American Mahjong Consecutive Run Hands
Consecutive run hands use neighboring numbers, but the exact spacing, suit colors, group sizes, and honor tiles vary by line. A rack with several connected numbers may point toward this section, yet a visually neat sequence is not enough by itself.
What makes a run promising
Look for repeated neighboring values, natural pairs, and the ability to support more than one printed line. A rack containing 4-4, 5-5-5, and 6-6 in related suits is more useful than a scattered collection containing one each of 2, 3, 4, 5, and 6.
Evaluate a consecutive run
- Identify the strongest two- or three-number cluster.
- Check whether the card permits one suit, two suits, or three suits.
- Protect required pairs before passing.
- Confirm whether flowers, dragons, or winds are included.
- Keep a nearby pivot line when possible.
Connected does not always mean efficient
Strong connection
Multiple copies of the exact neighboring numbers required by a line, with flexible suit placement.
Weak connection
Many different consecutive numbers but too few duplicates to form the printed pungs, kongs, or pairs.
Consecutive-run questions
Can a run wrap from 9 back to 1?
Only if the exact card line explicitly creates that pattern. Do not assume ordinary numerical wrapping.
Are consecutive hands always exposed?
No. Exposure status depends on the exact line.
When should I abandon a run?
Switch when required pairs remain remote, key numbers are heavily discarded, or another related hand has clearly better support.
