How many faan is Full Flush?
Full Flush contributes 7 faan in the HKMA reference and our game. All tiles in the winning structure must belong to one numbered suit; no winds or dragons are allowed. Chows, Pungs, Kongs and the pair must all meet that same suit condition.
An exposed hand may still be a Full Flush. Seven is the pattern value before other eligible bonuses. A table’s cap affects the final result, so “Full Flush is 7” and “this full-flush hand scores 8” can both be correct.
Worked example: Full Flush plus Concealed Hand
Three 1 Characters, 2-3-4, 4-5-6 and 7-8-9 Characters, plus a pair of 5 Characters. Every tile belongs to Characters.
With no exposed melds and a discard win, Full Flush 7 + Concealed Hand 1 reaches the 8-fan cap. The uncapped total cannot increase the final fan beyond 8.
Check every set and the pair
Choose one numbered suit, then check every tile, including the pair and exposed sets. A single honour changes the suit classification; any second numbered suit rules out both Full Flush and Half Flush.
Once the hand is complete, identify other scoring features under the same ruleset. Our game allows compatible ordinary additions but caps their total at 8. HKMA’s Concealed Hand bonus has different flower and Kong conditions, so do not transfer that bonus automatically.
Common miscount: one honour tile
Replace the pair of 5 Characters with a pair of White Dragons. The hand is no longer Full Flush. Because it still uses only Characters plus honours, it becomes Half Flush.
A tile from a second suited family is stricter still: with both Characters and Dots present, neither Half Flush nor Full Flush applies.
Full Flush + All Pungs: 10 before the cap
Four Pungs in one numbered suit and a pair in that suit qualify for Full Flush 7 + All Pungs 3 = 10. For example: triplets of 1, 3, 5 and 7 Characters, plus a pair of 9 Characters. Declare one triplet as exposed and use a discard win with no flowers or extra bonuses to isolate this combination.
That example reaches 10 in the HKMA reference. Our game keeps the 10-faan breakdown but settles at its 8-faan cap. Do not add Half Flush: this hand has no honours. In our game a qualifying limit pattern, such as Nine Gates, replaces ordinary pattern scoring.
7 fan; ordinary totals are capped at 8.

A hand to try
Win: discard · Seat: East · Round: East · Minimum: 3. Declared melds and special draw context are loaded with the hand.
With the saved win method, seat wind and round wind, this example is expected to score 8 final faan under sc_hk13_v1_2. The calculator also shows every contributing pattern and whether the hand reaches the selected minimum.

Can I call Chows or Pungs in a Full Flush?
Yes. All exposed sets must remain in the same numbered suit. Calling a set loses Concealed Hand but does not by itself lose Full Flush.
Does Full Flush plus self-draw always score 8?
The two pattern values are 7 + 1. Other eligible bonuses and the table’s cap still matter. Our game’s ordinary total cannot exceed 8; confirm the rules when playing elsewhere.
