is 1 , and the hand has to be closed. You declare it when the hand is one tile from winning, and you put a 1,000-point stick on the table.
The name on this site is riichi (立直). The glossary also lists it as Ready Declaration.
How you declare it
The EMA 2016 rules use three steps, and they match the glossary entry.
- Say riichi.
- Turn the sideways.
- Place a 1,000-point stick by your discards.
The hand is closed and in . A , a , or an before the declaration means you cannot declare it. If an opponent wins on that sideways discard, the declaration does not count, and the 1,000 points come back.
After a valid declaration the tiles stay as they are. The EMA 2016 rules allow one exception. You may call a closed when the drawn tile matches a concealed triplet, the wait stays the same, and those three tiles can only be read as a triplet. Three consecutive triplets in the same suit do not qualify, because those tiles can also be read as three identical sequences.
The stick
The stick is a 1,000-point bet, scored apart from the han. Win the hand and the stick comes back to you. If another player wins, they take it. If the hand draws, the stick stays on the table for the next player who wins.
A closed that scores only this yaku, at 30 fu, pays the 1 han 30 fu line. A collects 1,000. The dealer collects 1,500. Those payments have no . Sticks on the table are added on .
Ippatsu and double riichi
Ippatsu adds 1 han when you win inside one turn of the declaration, including your next draw. A chi, a pon, or a kan in that turn removes it. The EMA rules count a closed kan as a call here.
Double riichi scores 2 han for a declaration on your first discard, before anyone has called. A closed kan before that discard removes it. The 2 han is the whole value of the declaration.
A riichi win also opens the ura . The tiles under the dora indicators count for the player who declared. The glossary entry for ura dora names them.
Furiten
You may declare riichi while you are already furiten. Pass a winning discard after the declaration, and you stay until the hand ends. A still wins.
