'''Naki''' {{kana|鳴き}} are legal claims on immediately discarded tiles. The instant a discarded tile is declined for a claim, then it goes out of play and remains in the discard pile until the next hand. Discarded tiles gives players another source of tiles for hand completion, other than the regular wall.  Upon claiming a discard, the player's hand is then considered to be '''open'''. As a consequence, the player loses the option to call [[riichi]], and the hand is not eligible for [[menzen tsumo]] or other closed only yaku. Yet, some yaku allow the use of open hands, but they [[#Kuisagari|decrease in value by 1-han]], when opened.
'''Naki''' {{kana|鳴き}}, or "calls", are legal claims on an immediately discarded tile. When an opponent discards a tile you can claim, you can call it to add it to your hand. Upon claiming a discard, the player's hand is then considered ''open''. An open hand is unable to call [[riichi]] and is unable to score yaku like [[menzen tsumo]]. In addition, some yaku decrease in value after opening. However, opening the hand can allow you to complete it faster.


Tiles used for open calls are placed to the side.  When revealed, they are still part of a player's hand.  However, once placed to the side, tiles used for open calls can no longer be changed. As a consequence, the number of tiles for discard selection in a player's hand decreases with each tile call. From thirteen tiles, the count decreases to ten after one call; to seven after two calls; to four after three calls; and finally, to one after four calls. With this, a player's ability to [[defense|defend]] is reduced with every tile call.
== Properties ==
For each '''immediate''' discard, players may claim a tile if:
* The hand contains 2 out of the three tiles necessary to form a complete [[mentsu|meld]] (see below).
* The claim was made immediately after the discard, before the next player's turn. Otherwise, a discarded tile remains in the discard pile.
* If the discarded tile completes a hand, then any player may call ''ron'', overriding the other tile calls.


Yet, players may benefit from open tile calling from increasing the speed of hand development, convenience, or the irrelevance of losing hand value by opening. Players must also consider the number of tiles available.  Overall, tile calling is a discretionary move.  Especially with hands valued of [[scoring|mangan or greater]], opening the hand may be a better option than keeping it closed.
Calls are not mandatory. When making a call for a discarded tile (chii, pon, open kan), your hand is considered open. As mentioned above, open hands cannot call riichi, are ineligible for certain [[yaku]], and receive -1 han for certain other yaku.


Finally, the last discard cannot be claimed for any open calls, even if needed to attain [[tenpai]].  The call on the last discard is limited for winning hands, by which [[houtei raoyui]] is awarded.
Any call, except riichi, will immediately invalidate [[tenhou and chiihou|tenhou]], [[chiihou]], [[double riichi]], [[ippatsu]], and the option for [[kyuushu kyuuhai]].


==Mentsu and overview==
=== Procedure ===
When making a call, the tiles used for the call are revealed and placed to the side. These tiles are still considered part of the player's hand, but cannot be changed. Therefore, each call reduces the number of tiles you can choose to discard. After making a call, the player discards a tile.
 
The claimed tile must be arranged sideways to indicate the claimed tile. It must also be arranged on the left, middle, or right to indicate the source of the claim. This notation helps with the enforcement of [[furiten]], as a claimed tile is still a part of the original player's discard pile.
 
==Tile calls==
{{main|Mentsu}}
{{main|Mentsu}}


As a general rule, tile calls apply to the tile immediately discarded.  Naturally, players are not required to claim discarded tile; but they may do so under the condition of possessing 2 out of 3 tiles for a meld in the hand.  Every discarded tile not claimed by discard remain in the discard piles, until the [[Japanese_mahjong#End_of_a_hand|end of the hand]].
Tile calls can only be formed when it would complete a [[mentsu]] or complete a winning hand. These are shown below:
 
In addition, [[kuikae]] is an additional rule to tile calls.  Players may have tile groups within the hand; and a discarded tile may allow a tile claim.  If a player wishes to create a meld (an open group) using tiles in hand that form a complete group with the discarded tile, then a player is not allowed to discard such a tile that would have completed the tile group that same turn. Concerned tiles can be thrown at the next or subsequent turns, or kept in hand for future use.

For each '''immediate''' discard, players have the option to make claims on discarded tiles based on the following conditions:
* For all claims, a player must have 2 out of the 3 tiles in the hand necessary to form a complete [[mentsu|meld]].
* Discard claims must be made immediately after discard, and before the next player's turn. Otherwise, a discarded tile remains in the discard pile and may not be claimed.
* Players reveal their two tiles and append the claimed tile. Then these three revealed tiles are placed to the right corner of the player's area.
* The claimed tile must be arranged sideways to indicate the claimed tile.
* The claimed tile must be arranged on the left, middle, or right to indicate the source of the claim.
* The open tile call notation helps with the enforcement of [[furiten]], as claimed tiles are still noted as part of player discards.
* If the discarded tile completes a hand, then any player may call ''ron''.


===Chii===
===Chii===

{{#mjt:1'23s}}


'''Chii''' {{kana|チー}} is applied for opening sequential melds, to form minjun. To claim and complete '''sequences''', the player to the right of the discarder may claim the tile and call chii. This means, any player calling chii may only claim tiles from the player to the left.  Therefore, the tile turned sideways is always indicated on the left. Furthermore, this tile call may have a restriction named [[kuikae]], where chii is called using an existing sequential tile group.  In this case, the tile left over from the original, but now broken, tile group cannot be discarded. The player is forced to discard another tile.
'''Chii''' {{kana|チー}} completes a sequence, to form minjun.
 
Only the player to the right of the discarded may call chii. In other words, you can only call chii from the left player's discards.  Therefore, the tile turned sideways is always indicated on the left. Chii may be particularly subject to the rule of [[#Kuikae|kuikae]] - when calling a sequence, you cannot discard a tile that would have completed the same sequence. See below for details.

Toitsu, or pairs, may be upgraded to minkou, or open triplets.  Unlike "chii", the call for '''pon''' {{kana|ポン}} may be called from any player on the board. As long as a player possess two identical tiles and a third is discarded, the player may call for that discarded tile regardless.  Because any player may call, sometimes a player's turn may be skipped.
 
'''Pon''' {{kana|ポン}} turns a pair of identical tiles into a minkou (open triplet).

{{main|Kan}}


'''Kan''' {{kana|カン}} may work like pon, except this call has some added procedures and additional situations. Likewise, the tile arrangements works similarly to pon.  However, there is the addition of the other two kan types: [[ankan]] and [[shouminkan]].  For ankan, the hand remains closed, despite the use of a tile call. Instead, such a call is used to invoke the rules specific to kan; and certainly, kan does have some specific rules applied. Mostly, these relate to the [[dead wall]] and the revealing of additional [[dora]].
'''Kan''' {{kana|カン}} are triplets "upgraded" into four-of-a-kinds. Unlike the other calls, kan has some added procedures. In addition, there are three different types of kan:
*Daminkan (open kan) are called like pon, except you need three of the same tile.
*Ankan (closed kan) can be called when four of the same tile are in your hand (without needing to claim a discarded tile). Ankan ''does not open your hand''. You are not allowed to call ankan immediately after calling pon or chii.
*Shouminkan (added kan) can be called when you have previously called pon, then draw the fourth tile yourself. This call turns the called triplet into a kan call.
 
All forms of kan are still considered triplets, just with one extra tile. Therefore, in order to maintain the hand, one tile is drawn from the dead wall. Also, any form of kan reveals [[kandora]]. For more information, see the [[kan]] page.

'''Agari''' {{kana|アガリ}} is the generic call for a winning tile. However, this is a general term for the state of winning.  It is rare, if ever, do anyone use this term to declare a winning hand.

===Ron===
===Ron===
'''Ron''' {{kana|ロン}} is a specific tile call on a discard, when the discard actually completes the hand.  Also, the hand must have a valid [[yaku]]. Under [[furiten]], a player may not call ron, otherwise, it is a violation of rules and subject to [[chombo]] penalty.
'''Ron''' {{kana|ロン}} is a tile call to win from a discarded tile. Under [[furiten]], a player may not call ron; otherwise, it is a violation of rules and subject to [[chombo]] penalty. Note: you must also have a [[yaku]] in order to declare a win.
 
Ron opens the ''group'' of tiles, but does not open the ''hand''. When competing a triplet via ron, the triplet is worth reduced [[fu]], and the triplet no longer counts as a "closed triplet" in regards to [[sanankou]] / [[suuankou]]. The hand itself is not opened, though, so yaku like [[iipeikou]] are unaffected (even if the winning tile completes the iipeikou, it still counts).


===Call precedence===
===Call precedence===


The different tiles calls take precedence.
When multiple players can call a tile, the following takes precedence:
#Ron or Agari
#Ron or Agari
#Kan or Pon
#Kan or Pon
#Chii
#Chii


It is impossible for kan and pon to be called simultaneously. However, either can simultaneously occur with chii.  Due to precedence, the player, who calls kan or pon, gains the right to a discarded tile over a chii call. Overall, the call for ron or agari supercedes all tile discard calls.
It is impossible for kan and pon to be called simultaneously. A call for kan requires 3 copies of a tile, the call for pon requires 2 more copies of a tile, but there are only 4 tiles total. It is possible for pon/kan and chii to be called together; the player who calls pon gets the tile. A call for ron/agari will override any other tile call.


==Kuisagari==
== Kuikae ==
'''Kuisagari''' {{kana|喰い下がり}} is a property of some yaku to lose value when [[naki|called open]].  When calling on a discard and opening the hand, a player sacrifices the value of 1-han per yaku affected by this rule. The loss in value is obviously bad, though calling allows you to develop your hand faster. If certain tiles are discarded, a player may need to make the open call, or not score the yaku at all. Also, if the hand is already valuable enough (e.g. from having [[dora]]), the loss of value can be deemed worthwhile.
{{Main|Kuikae}}


Similarly, some yaku can only be scored with a closed hand. Certain yaku, like [[chiitoitsu]] and [[mentsumo]], are closed based on their structure or nature. Other yaku, like [iipeikou]], the requirement of a closed hand is entirely artificial. Unlike instances of kuisagari, you cannot use these yaku to fulfill the yaku requirement of an open hand: these are not considered 0 han yaku. For [[ryanpeikou]] in particular, if it were affected by kuisagari, it would score 2 han when opened. In actuality, you cannot achieve ryanpeikou at all with an open hand.
Kuikae is a rule which, when making a call, prevents you from immediately discarding a tile that could have completed that call. Under kuikae, calling pon on a 5-pin, then discarding a 5-pin is not allowed. Similarly, after calling chii on a 4-sou with 23-sou, you cannot discard a 1-sou or 4-sou. You are allowed to discard these tiles on any turn afterwards, just not on the turn you made the call. While it is not a fundamental rule, the kuikae restriction is common.


Finally, some yaku are not affected by kuisagari.  Even when open, they retain their original han value.  These are [[yakuhai]], [[toitoi]], [[sanankou]], [[sanshoku doukou]], [[shousangen]], [[sankantsu]], as well as any [[yakuman]] that can be scored with an open hand.

{{main|Haipai}}
{{main|Naki strategy}}
With regards to mahjong hands, the common question looks to determine the best practices of opening or closing a hand.  For starters, players should know the [[yaku]] and their han values.  Essentially, this begs the question: "Is it worth opening the hand, or is it better to remain closed?"  Naturally, there are advantages and disadvantages to either approach.  For both cases, the speed at which a hand attains [[tenpai]] rests on this decision.  If a hand does not improve its [[shanten]] count, then it may not be worth calling, unless a specific goal is in mind.


For various [[yakuman]] hands, it is certainly advantageous to make calls on specific tiles. The sheer difficulty of yakuman hands overall make it necessary to make use of tile calls to even come near completion, much less score one.
Before making a tile call, players should consider "is it worth opening the hand, or is it better to remain closed?" Naturally, there are advantages to both. For starters, players should know the [[yaku]] and their hand values. A closed hand can call riichi and is worth more; an open hand is faster. Players should consider their point standing, hand value, number of tile draws left, and other factors before opening. For more details, see [[naki strategy]].


== Strategy ==
[[Yakuman]] hands, assuming they can be won open, don't reduce in value after a call. Since they are so hard to complete, opening is often necessary to actually win with one.
