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.

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.

This is the easiest one to understand, when you've discarded a tile that would let you agari!

Pattern 1

Pattern 1

Reason for furiten

You'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.

You'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.

In this situation, all you can do is change your wait or win via tsumo.

In this situation, all you can do is change your wait or win via tsumo.

Pattern 2

When another player has discarded the tile you need to win, you didn't call ron, and you haven't drawn again yet.

When another player has discarded the tile you need to win, you didn't call ron, and you haven't drawn again yet.

In furiten so you can't ron

Did not ron

Your 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.

Your 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 your next draw, this furiten state is cleared.

After declaring riichi, you let the tile you need to win go by without calling ron or tsumo!

Pattern 3

Did not ron

Furiten so you can't ron

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.

Looking at it from the other side, any tile after riichi that goes by without ron or tsumo becomes a safe tile.

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!

How was that! This time, I did my homework perfectly!

You're right, well done.
