'''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.
