Chii toitsu, also known as chii toi or nico nico, is one of the standard yaku hands. This hand consists of seven pairs, where no two pairs may be identical (i.e. a quad may not be considered two separate pairs). This hand is one of the two exceptions of the "four melds and one pair" rule of forming a hand, where the other exception is the kokushi musou. This hand is closed only.

By default, this hand is always given 25 fu. In addition, a chii toitsu tenpai always uses a 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 chii toitsu hands. Although, the 25 fu column is equivalent to 50 fu numbers.
