==Rules==

After any time a player has a closed ''tenpai'' hand, the player may declare riichi. ~~Upon doing~~ so, the hand ~~instantly gains the potential to win~~ 1 han. To declare riichi, a player announces riichi and deposits 1000 points onto the table. Then the player discards a tile facing sideways in the discard pile. This is done to indicate when riichi was called. If that tile is claimed by another player, then the next discard is turned sideways as a replacement. After a riichi declaration, the hand remains locked and unchangeable. In this state, the player is simply waiting for a winning tile to appear, either by draw or discard.

=== Ippatsu ===

This yaku is awarded if the player receives a winning tile within an uninterrupted set of turns after the winning declaration. Tile calls interrupt the set of turns. The latest possible chance to win with ippatsu is with the player's next drawn tile after the riichi declaration.

Ippatsu is worth an extra 1 han.

=== Double riichi ===

Double riichi is a special case for riichi, where the player declares riichi ~~with a dealt hand~~. In turn, the ~~very first discard~~ is ~~the tile turned sideways~~.

Double riichi is a special case for riichi, where the player declares riichi on his first turn. No tile call may have interrupted the turn order before the declaration.

Double riichi is worth 2 han instead of 1 han.

=== Kan during riichi ===

Line 26:

Line 32:

If a riichi declarer does not win at first opportunity, he will be permanently [[Furiten|furiten]].

==Advantages==

=== Ura dora ===

When a riichi declarer wins, he may flip the tiles underneath the [[dora]] and kan dora indicators. These flipped ''ura dora indicators'' may increase the value of his hand.

== Strategy ==

=== Advantages ===

Any closed hand becomes eligible for winning by ron.

Kans formed by any player provide two extra dora indicators for the riichi declarer instead of one.

=== Disadvantages ===

~~==Disadvantages==~~

It is less likely for opponents to deal in.
