List of special rooms in Mahjong Soul: Difference between revisions

'''Bloodshed Skirmish''' {{kana|赤血の戦}} <small style="color:#999;">(''Sekketsu no sen'')</small> is a special room applying gameplay of Sichuan Bloody Rules: ''Battle to the Bloody End'' (血战到底). As described, the room has a unique scoring system completely different from riichi mahjong. Unlike riichi, aggressive strats are more preferred, while many defensive strats under riichi are no longer useful, sometimes even leads to a heavy penalty if trying to do so.

Each match has and only has four rounds.  Instead of rotating towards each player, the dealership is determined by the first winner in the previous round, or keeps if nobody wins. Honor tiles are not used, meaning only suited tiles are available, 108 tiles in total.  Each player are forced to make valid hands with at most two of the suits ('''Voided Suit''' {{kana|[https://ja.wikipedia.org/wiki/絶一門 絶一門]}} <small style="color:#999;">(''zetsuichimon'')</small>), failing to do so leads to a heavy penalty in exhaustive draw.  Similar to most mahjong variants, furiten is not applied.

** Three players declared winning. (Ends normally.)

** Any player is bankrupted. (A match is also ended in this case.)

Generally speaking, the score of a hand is only determined by han value:

: <code>Points = 1000 * 2 ^ Han</code>

The upper bound of han value is 6 han. The scoring table can be simply listed as follows:

The payment is applied differently to riichi. In brief, it's more encouraged to win by Tsumo, as the total payment is huge compared to Ron. More specifically, payments are counted as follows:

* Tsumo: Every current non-winners should pay exactly the points to the winner, with 1,000 points each in addition.

Additionally, when a kan is called, an instant bonus is applied to each kan immediately.

* Added kan from draw <small style="color:#999;">(''Tsumogiri kakan'')</small>: Each non-winners pay 1,000 points towards kan-claimer. However, if the tile deals into others, no payment will be applied.

* Added kan from hand <small style="color:#999;">(''Tedashi kakan'')</small>: No payment.

* Concealed kan <small style="color:#999;">(''Ankan'')</small>: Each non-winners pay 2,000 points towards kan-claimer.

However, if the round ends by exhaustive draw, while some of them fails on hand rechecking, kan bonuses from those players will be refunded in ryuukyoku.

Base yakus are the main yaku. Only one of them can be chosen for each hand, with their han value as high as possible.

Bonus yakus are additional. They can be stacked arbitrarily as long as the condition is satisfied. Usually those are occasional yakus aside from Root.

* (1 han) '''Yakuless Win''' {{kana|無番和}} <small style="color:#999;">(''Uufanhou'')</small>: As described, neither of other yaku is satisfied. This can be treated as matching the lowest winning condition: Voided Suit is satisfied.
