Consecutive Run Hands in American Mahjong
Consecutive Run is one of the most flexible card sections because its numbers can begin at different points. That flexibility helps beginners, but only if the printed group sizes and suit relationships remain exact.
Quick answer
A Consecutive Run hand uses numbers that follow one another, such as 1-2-3 or 5-6-7, in the structure printed on the card. Choose the starting number and suits allowed by that line, then preserve required pairs and exact group sizes.
Find the possible run
Look for neighboring numbers already on the rack. A strong pair plus several tiles one number above or below often creates more than one possible starting point.
Check the range. A run cannot extend below one or above nine, so edge numbers reduce the possible directions.
Read suits and groups
Consecutive numbers do not automatically mean one suit. The printed colors decide whether the groups use one, two, or three suits.
Spacing and repeated symbols show whether a number is a pair, pung, or kong. Do not rearrange group sizes just because the sequence remains consecutive.
Plan a nearby pivot
The best backup hand often shifts the run by one number while preserving a pair or completed group. Keep that pivot in mind during the Charleston.
Once exposures appear, flexibility drops. Confirm the exact line before calling a tile.
Beginner checklist
- Identify neighboring numbers
- Check the 1-to-9 range
- Map card colors to suits
- Protect required pairs
- Keep a one-step backup run
Compact and travel-table note
Arrange mini tiles with small gaps between number groups. Clear spacing helps the eye see the run without mistaking separate pairs for one long sequence.
Rules authority
The National Mah Jongg League publishes the American version of the rules and the annual Standard Hands and Rules card. Use the current card and official materials when a tournament-level ruling matters.
