 {{main|Scoring table}}
-By default, this hand is always given 25 fu.  In addition, a chiitoitsu [[tenpai]] always uses a [[Machi#Tanki|tanki machi]] (wait).  Normally, that wait pattern is awarded 2 fu but not in this case.  Finally, the 25 fu number is not rounded up to 30 fu.  In turn, the scoring table produces an independent set of point exchanges applied to chiitoitsu hands.  Although, the 25 fu column is equivalent to 50 fu numbers.  Once a chiitoitsu hand is valued at 5 han or greater, then it is counted for [[mangan]] or greater.  Finally, chiitoitsu with [[mentsumo]] produces a 3-han hand.  Therefore, it is not possible to produce a 2-han chiitoitsu hand by tsumo.
+As a special exception to the usual scoring rules, this hand is always given 25 [[fu]].  No other fu are awarded, even though a chiitoitsu hand would qualify for 2 fu due to the [[tanki|pair wait]] which it must have.  The value is not rounded up to 30 fu.  This produces a unique set of scoring values for chiitoitsu hands at a given han value, although they are the same as a hand with one fewer han and 50 fu.  Like all hands, once a chiitoitsu hand is valued at 5 han or more, then it is counted for [[mangan]] or greater.  Chiitoitsu with [[mentsumo]] produces a 3-han hand.  Since chiitoitsu can only occur in a closed hand, it is not possible to produce a 2-han chiitoitsu hand by tsumo.

-High scoring chiitoitsu hands are possible without dora.  The highest possible involves riichi, ippatsu, tsumo, tanyao, and chinitsu.  Add the 2 han for chitoitsu, this combination brings the hand to a whopping 12 han.  Then add haitei or houtei, then such a hand becomes a [[kazoe yakuman]]. The hand 22334455667788 pinzu contains chiitoitsu, but it's more advantageous to count it as ryanpeiko and pinfu. In some [[rule variations#Daisharin|rule variations]], this hand is an [[optional yaku|optional yakuman]], known as "daisharin".
+High scoring chiitoitsu hands are possible without dora.  The highest possible involves [[riichi]], [[ippatsu]], [[menzenchin tsumohou|tsumo]], [[haitei raoyue and houtei raoyui|haitei]] and [[chinitsu]].  With the 2 han for chitoitsu, the combination brings the hand to a whopping 12 han.  Note that [[tanyao]] cannot be added, as the hand 22334455667788 can be scored as [[ryanpeikou]] and [[pinfu]] for an additional 2 han over chiitoitsu. In some [[rule variations#Daisharin|rule variations]], this hand is an [[optional yaku|optional yakuman]], known as "daisharin", "daichikurin", or "daisuurin", depending on the suit..
