It's worth 2 han, or 1 with kuisagari.
It's a yaku where you get 1-9 of the same type of tile and use them as three shuntsu.
Since there aren't many things you can combine it with and the tiles are arranged as shuntsu, it's very easy to end up with a cheap hand.Might be ikkitsuukan depending on which tile is used for agariCannot make ikkitsuukanContains iipeikouExampleWaitMight be iipeikou depending on which tile is used for agariIs not iipeikou due to fuuroExample of ryanpeikouIf you do this with koutsu instead of shuntsu it becomes "sanshoku doukou", which does not have kuisagari applied.Contains sanshoku doujunBasically, it only looks cool.Contains ikkitsuukanThe next thing we'll introduce is "iipeikou".
Iipeikou is a yaku worth 1 han which you make by having two of the same shuntsu with the same type of tiles.
This yaku is menzen-only, so even if you have two copies of the same shuntsu with the same type of tile, if you've called any tiles, you can't make this.If you're tenpai like in example 2, you'll make iipeikou if you get the 6-pin, but not if you get the 9-pin.
Thus, getting the 6-pin is takame (worth more points) and getting the 9-pin is yasume (worth fewer points).
By the way, if you have two separate iipeikou it becomes ryanpeikou, a yaku worth 3 han!Next is "sanshoku doujun".
It's worth 2 han and becomes 1 han via kuisagari.
Sanshoku (3 colors) means wanzu, souzu, and pinzu;
doujun (same order) means the same line of numbers.
Thus, it's when you have the same shuntsu in wanzu, souzu, and pinzu.
Sanshoku doujun is easy to combine with tan'yao and pinfu, and while kuisagari is applied, you can still make it with called tiles, so it's a fairly commonly used yaku.
