Suit Burden in American Mahjong Hands
Suit burden describes how much a card line depends on exact suit assignments. A hand may require one suit throughout, three different suits in a fixed relationship, or two suits with specific groups assigned to each printed color.
Printed Colors Create Structural Commitments
The colors on an American mahjong card are relational. One printed color means one suit, a second color means a different suit, and a third means the remaining suit. Once the rack is mapped to a line, the numbered groups must preserve that relationship.
A low-burden hand may allow more than one sensible suit assignment. A high-burden hand may work only if exact groups appear in exact suits, making every off-suit tile less useful.
Low and High Suit Burden
Lower Burden
The rack supports multiple suit mappings, repeated ranks work in several suits, or a connected alternate line uses the same tiles.
Higher Burden
The line requires exact suit placement, the rack is split awkwardly, and changing one color assignment would invalidate several groups.

Suit-Burden Questions
Does a one-suit hand always have high suit burden?
It can, especially when the rack is not already concentrated. However, a strong one-suit rack may be simpler than a rigid three-suit pattern.
Can the same printed color represent different suits within one line?
No. A printed color keeps the same suit meaning throughout that line.
Should I decide suit assignments before the Charleston?
Test likely mappings, but preserve flexibility until the rack provides enough evidence to commit.
