This is the easiest one to understand, when you've discarded a tile that would let you agari!Pattern 1You'll discard the 7-sou and wait for the 5-pin or 8-pin, but on the 6th turn you discarded a 5-pin so you're furiten.By the way, if you accidentally try to win when prevented by furiten it's a chonbo and you must pay out a mangan's worth of points!You're right, well done.In this situation, all you can do is change your wait or win via tsumo.Reason for furitenIn furiten so you can't ronDid not ronYour wait is 1-wan, 4-wan, 7-wan, but you let your shimocha's 7-wan pass so you're in furiten within the turn.
Thus, you can't win on your toimen's 4-wan.After declaring riichi, you let the tile you need to win go by without calling ron or tsumo!Pattern 3Did not ronFuriten so you can't ronLooking at it from the other side, any tile after riichi that goes by without ron or tsumo becomes a safe tile.How was that! This time, I did my homework perfectly!Pattern 2"Next time, explain about calculating points."Please, no more homework~In turn 7, you declared riichi with a 3-wan, 6-wan, chun wait, then in the 8th turn, you let your toimen's chun pass, so you're in furiten and can only win via tsumo.When another player has discarded the tile you need to win, you didn't call ron, and you haven't drawn again yet.After your next draw, this furiten state is cleared.Next up, I'll talk about furiten!
Furiten is a special situation in which, despite being in tenpai, you can't agari.
(If you declare agari, you'll be penalized.)
There are 3 patterns of furiten.Then, as a reward, I'll give this to you.Might that be tacos!?P.S.
