'''Open riichi''' {{kana|オープン立直}} is an [[optional yaku]] which is a modified version of riichi. The mechanics are identical to a normal riichi, except that you must reveal either your entire hand or its tile [[wait]]s. This makes it trivial for others to defend against the riichi.  In exchange, an open riichi is worth 1 extra han.  In general, the intent involves winning by self-draw.

As a further optional rule, yakuman may be awarded if any player intentionally [[ron|plays into]] the open riichi. This is more or less a harsh penalty for playing into a revealed hand. Many official organizations and tournaments do not implement open riichi; it is more or less reserved for casual or gambling game settings.
