Riichi: Difference between revisions

'''Open riichi''' {{kana|オープン立直}} is an [[optional yaku]], which is a modified version to riichi itself. The principle works exactly in the same way as the original riichi.  However, there is an added bonus of 1-han attached, which is earned by revealing either the hand or the tile waits. This naturally eases everyone else's ability to defend against the riichi.  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.
