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 and for having difficult wait. If none of these elements exist in a non-[[toitoi]] hand without quads, it is ''always'' 40 fu when closed and ''always 30'' fu when open.

Counting fu for [[toitoi]] is a bit trickier but only ''open'' [[toitoi]] hands need to be considered: if you win a closed [[toitoi]] hand by tsumo, it's a yakuman ([[suuankou]]) and if you win a closed [[toitoi]] hand by ron, it's a mangan or higher ([[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.
