The tileset includes one red five per suit.


Turn order is considered interrupted by any call of Chii, Pon, or Kan, even when declaring a concealed kan.
Turn order is considered interrupted by any call of Chii, Pon, or Kan, even when declaring a concealed kan.
After calling Pon or Chii, any tile may be discarded by the caller. It is therefore legal to discard the same tile as the one called, or a tile which would have completed the now-open meld on the other side.


Ura dora, kan dora, and kan ura dora are used. After declaring any type of kantsu, the next dora indicator is flipped immediately.

Double and triple Ron is allowed, the discarder has to pay each winner separately.

Temporary Furiten is cancelled when the player takes a tile from the wall, and also on any interruption of turn order.
Temporary Furiten is cancelled only when the player takes a tile from the wall.


A player is karaten (empty tenpai) if his hand could be completed with one more tile, but all possible winning tiles are already used in his own hand. Open melds and kantsu belong to his hand. Karaten counts as noten.

[[Kuitan|Open tanyao]] is allowed.
[[Kuitan|Open tanyao]] is allowed.
[[Nagashi mangan]] counts as a win, rendering [[ryuukyoku|noten penalties]] and noten riichi [[chombo|chombo]] void. Multiple players may win with Nagashi Mangan simultaneously, payments occur as with separate mangan Tsumos. Table counters affect the hand score normally. Hand progression or hand repeat depends on whether East was a nagashi mangan winner or not, because tenpai hands are not revealed.
[[Rinshan kaihou]] combines with [[Haitei]] when a kan is declared with exactly one tile in the live wall and the declarer wins on the subsequent dead wall draw. This is not possible in most other rulesets.


[[Renhou]] is a mangan. This is awarded to any player winning by Ron within the first uninterrupted set of turns, before the player has made his first draw from the wall. The winner does not need to have another yaku, Renhou by itself is the yaku.

Yakuman are not cumulative. Daisuushii is the only possible double yakuman.

=== Scoring ===
=== Scoring ===
All players start with 30,000 points. Point sticks are used to keep count of points during the game.


Scores are kept on paper, there are no point sticks. Players start with 0 points and may sink into negative scores without ending the game.
In case a player goes negative on points, a "penalty" 10,000 point stick is usually handed to them by the tournament judge in order to carry out further point transactions and resume play. This is ultimately subtracted from the player's end score.


Players may declare Riichi with any score. Tournaments often provide each player with a single 1,000-point-stick for Riichi declarations. Winning players always get one Riichi stick back. Leftover Riichi sticks go to the winner sitting closest to the discarder's right.

Table counters are added whenever East won a hand, or there was an exhaustive or abortive draw. Table counters are all removed when someone else than East wins and East does not. Chombo leads to a repetition of the hand with the same number of table counters.

When five or more table counters are present, winning hands must have at least two han, coming from yaku.
After each Hanchan, players receive a relatively large [[Uma|uma]] of 5-15, i.e., the second player receives 5,000 points from the third, and the first player receives 15,000 points from last place. When player scores tie, the tying players share their Uma; ties are not resolved by player seating order. Players tying for first share any leftover Riichi sticks. There is no [[Oka|oka]]. Scores are ''not'' rounded to the nearest thousand.

Scores are ''not'' rounded to the nearest thousand.
In the end of the Hanchan, the scores of each player are typically marked as the difference between the starting points (30,000) and their current amount of points, divided by 1,000. Uma is added on top of this to form the total. For example, a player finishing at 1st place with 60,000 points would mark their score as +30, followed by the uma (+15), totaling up to +45. Finally, any penalties (e.g. for a chombo) are subtracted from the liable players' total score for that Hanchan.


=== Time limit ===
=== Time limit ===


When played with a time limit, a gong sounds 15 minutes before end. Only one more valid hand may be started after the gong. A hand starts when the dice are thrown. Won hands, exhaustive draws, and abortive draws all constitute a valid hand. Chombo renders a hand invalid, therefore another hand must be played.
