List of special rooms in Mahjong Soul: Difference between revisions

== Casual Room ==

'''Casual Room''' {{kana|交流の間}} <small style="color:#999;">(''Kouryuu no ma'')</small> provides a casual gameplay, without requiring creating a friendly room and find sufficient players manually. The ruleset is identical to normal gameplay. There is no rank change or copper payment, but you cannot gain bond points or chest rewards.

Casual Room is long-term available.

'''DoraDorara''' {{kana|ドラさんモード}} <small style="color:#999;">(''Dorasan moudo'')</small> is a special room with 3 dora indicators revealed in advance. The maximum amount of dora still remains at 5 (plus the 5 uradora), so only the first two kans reveal dora indicators.

== Chaotic Wall Break ==

'''Chaotic Wall Break''' {{kana|龍の割目}} <small style="color:#999;">(''Ryuu no wareme'')</small> is a special room with three dora indicators revealed in advance, as well as applying a special [[wareme]] rule. The dora work in the same way as in [[#DoraDorara]].

One player is designated as the wareme. The payment to and from the wareme player is doubled (excluding honba and riichi bets). Due to the lack of physical wall position, the game determines the wareme player in a different way. In each round, one random player get a wareme marker. This switches randomly every five turns. The same player can be chosen when the marker switches.

'''Path of Trial''' {{kana|試練の道}} <small style="color:#999;">(''Shiren no michi'')</small> provides a gameplay with ruleset identical to Ranked Rooms. Instead of ranking, player's goal is to complete several missions in a mission card, and try to accomplish mission cards as much as possible. Each card is restricted to be finished in at most 5 matches. An internal ranking is available, ordered by Trial Level.  By completing more cards, player's level gets promoted, along with enchanced difficulty of missions.

*The charleston - at the start of the hand, players must select 3 tiles of their choice to exchange with another opponent.

*Resumed play - after a player wins a hand, the round does not end. It only ends when three players have won, tiles are drawn into [[ryuukyoku]], or when a player falls into a negative score. Players that win can no longer draw tiles or lose points.

'''Bloodshed Skirmish''' {{kana|赤血の戦}} <small style="color:#999;">(''Sekketsu no sen'')</small> applies the gameplay of Sichuan Bloody Rules: ''Battle to the Bloody End'' (血战到底). The ruleset and the scoring system are completely different from riichi mahjong. Unlike riichi, offense is heavily preferred, and many defensive strats are no longer useful (some even punished with a heavy penalty).

*Instead of seat winds rotating towards each player, the dealership is determined by who won the previous round. The first winner becomes east, the second winner becomes south, and so on. If no player wins, the seats are kept. There is no score bonus for being the dealer.

*Honor tiles are not used, meaning only suited tiles are available, including 108 tiles in total.  

*Each player is forced to exclude a suit ('''Voided Suit''' {{kana|[https://ja.wikipedia.org/wiki/絶一門 絶一門]}} <small style="color:#999;">(''Zetsuichimon'')</small>), thus making a valid hand with at most two suits. Failing to do so leads to a heavy penalty in exhaustive draw.

*There is no [[furiten]], [[dora]], or [[dead wall]] <small style="color:#999;">(''wanpai'')</small> tiles.

*The scoring system and yaku are much different than riichi mahjong (see below for details).

The score of a hand is only determined by han value and if it won via [[tsumo]].

In brief, tsumo is worth much more than ron. Also, there is no bonus for being the dealer.

However, if the round ends by exhaustive draw, and a kan-declaring payer is not tenpai, any kan payments are refunded. If a kan player is holding an excluded suit, the kan payment is also refunded.

Base yakus are the main yaku. Only one of them can be chosen for each hand, with their han value as high as possible. These yaku cannot be stacked together, neither can a player score them with more han by combining base yaku together.

*: As described, neither of other yaku is satisfied.

*: Winning by the discards from other players who just called a kan.

Overall, base yaku can be classified under several variants. The following rules can help to memorize the list by decomposing the yaku.

* Not-ready <small style="color:#999;">(''noten'')</small>: Pays for the ''highest'' possible score <small style="color:#999;">(''takame'')</small> towards ready players, as if they already dealed into others in game (occasional yakus won't be counted, of course).  

* Pied: Pay all non-winning opponents, including those who are not-ready. In addition, the payment is set a minimum of 4 han.

SBR is much more offensive than riichi mahjong. With such high noten penalties, it is always recommended to try to keep tenpai (or at least, advance towards it). If you give up tenpai, you'll just have to pay it back at the exhaustive draw. Trying to hold a tile from the excluded suit is always risky and almost never recommended. Due to those reasons, and because [[furiten]] is not enabled, defense is much weaker than usual.

There is no score penalty towards opening your hand. Therefore, triplets are more powerful, and [[shanpon]] waits become more common.

A hand using sequences rarely scores yaku. The only yaku that allow sequences are chinitsu, junchan, root, and the other bonus yaku.

 

'''Event Room''' {{kana|特別対局}} <small style="color:#999;">(''Tokubetsu taikyoku'')</small> is a room for event purpose.  Despite its name, there's nothing special at all to the room: it follows every regular settings of 4P-East gameplay, requiring standard payment identical to Silver Room, as well as progress of opening Casual Chest / Ichihime's Gift Box.

*On a win, for each fortune tile in hand, the hand's score increases by x(fortune_tiles + 1). This equates to x5 with four tiles, x4 with three tiles, x3 with two tiles, and x2 with one tile. This does not affect points from riichi bets or honba.

'''Battle of Incantation''' is a special room introduced with the collab with [[wikipedia:Fate/kaleid liner Prisma Illya|Fate/kaleid liner Prisma Illya]]. The rules are the same as regular 4P mahjong, except with the addition of Azure Bonus and Crimson Bonus.

*Crimson Bonus is gained for each consecutive tsumogiri discard (discarding the tile you drew) in the pond. The bonus is equal to 1 han for 3 discards, 2 han for 5 discards, 3 han for ? discards, 5 han for ? discards, 12 han for 12 discards.

A hand can score both the Azure Bonus and the Crimson Bonus. Notethat bonuses consider the amount of consecutive tiles ''in the pond''. Therefore, an opponent [[naki|calling]] a discard means that tile won't count towards either bonus. Also, the tedashi/tsumogiri discards have to be consecutive, so 2 tedashi -> 1 tsumogiri -> 1 tedanshi does not grant Azure Bonus 1.

== Tournament ==

The '''tournament lobby''' is a permanent fixture in the game. Users have the ability to pay 60 Jade to create tournament lobbies. They may apply special rule customizations for their desired tournament or otherwise utilize default rule settings. A number of clubs, individuals, and Yostar itself have hosted tournaments.
