Pure Terminal Chows (一色雙龍會)
Two 1-2-3 chows, two 7-8-9 chows, and a pair of 5, all in the same suit. The most elegant chow-only limit hand.
How Pure Terminal Chows (一色雙龍會) works
A single suit arranged as two 1-2-3 chows, two 7-8-9 chows, and a pair of 5s.
All fourteen tiles are in one suit forming the precise shape 123-123-789-789-55, two identical low runs and two identical high runs flanking a pair of fives. The fixed structure makes it a distinctive one-suit pattern. Because the suit is pure and the chows are doubled, ordinary one-suit and identical-chow fan implied by the layout are subsumed rather than counted separately.
- •The pair must be the 5 of the same suit; any other pair breaks the pattern.
- •It is a flush hand, so the lower full-flush fan it contains is not scored again.
- •The doubled low and high chows mean identical-chow fan is implied and absorbed.
