If the hand is won by tsumo, then [[sanankou]] and [[mentsumo]] will be scored. If the triplet of [[ton|east]] is closed, then [[sanankou]] will still be scored. Finally, the last group must be a sequence, or [[toitoi]] would be scored. Any of these cases will add han to the hand. | |||

This is the greatest fu count for any hand worth 2 han. The third quad means that [[sankantsu]] must be the only yaku, but one must still be open in order to avoid [[sanankou]].

Unlike the 1 han 110 fu example, there is a little bit of leeway: for instance, the hand could be completed on a ron, while lacking a double wind pair, and still score 110 fu. | ||
Because of the [[mangan]] limit, counting this many fu for anything 3 han or higher is no longer relevant, because any hand with 3 han 70 fu or more is capped at mangan. | Because of the [[mangan]] limit, counting this many fu for anything 3 han or higher is no longer relevant, because any hand with 3 han 70 fu or more is capped at mangan. | ||

All of the above are worth 8 fu and thus may raise the total fu count by 10 when combined with the 2 fu for tsumo or for having difficult wait. | All of the above are worth 8 fu and thus may raise the total fu count by 10 when combined with the 2 fu for tsumo or for having difficult wait. | ||
Counting fu for [[toitoi]] is a bit trickier but only ''open'' [[toitoi]] hands need to be considered: | Counting fu for [[toitoi]] is a bit trickier, but only ''open'' [[toitoi]] hands need to be considered: a closed toitoi is, at minimum, a mangan (toitoi + [[sanankou]]). Also, a [[toitoi]] hand with only terminals/honors is [[honroutou]], also worth at least a mangan. Thus, an open [[toitoi]] hand with no quads (for which counting fu actually matters) will almost always score 40 fu. | ||
