:This is the last possible chance for riichi to be called in this hand, when there are eighteen tiles left in the walls, counting the dead wall.  So, that leaves four tiles left for regular player draws.  For haitei then, the fourth remaining and last tile tile draw goes to the riichi caller.

In this example, the hand wins from an opponent discard before the next tile draw.  However, two tile calls were made prior to the win.  So, ippatsu is invalid here.

Unlike riichi, ippatsu is not compatible with every other yaku.  Only two cannot mix with ippatsu: [[rinshan kaihou]] and [[houtei raoyui]].  Regarding rinshan kaihou, the required call for [[kan]] to invoke rinshan already cancels out ippatsu.  As for houtei, the following example for haitei shows the last possible chance to call riichi, which aims for [[haitei raoyue]].
