The Table Is the Battlefield

This is not ordinary mahjong. Your hand is your weapon — the sets you build determine your damage multiplier. The more tiles you match in one suit, the more special sets you complete, the more absurd the number you hit for. Four players draw and discard in turn; whoever completes their hand first, fires.

90 Monsters, Three Worlds

Draft three monsters from five candidates at the start. When your active monster falls, the next one steps up. Lose all three and you're out.

• Base — Giants, Serpents, Knights, Warlocks, Divine Beasts
  
• Dinosaur — Carnivores, Herbivores
  
• Hyakki — Oni, Beast Spirits, Strange Ones

Every monster has its own passive or active skill: one converts damage into healing, one strikes only the two highest-HP targets, one seals an opponent's skills for six turns. How you build your roster is the first decision of the match.

Rule Cards Rewrite the Game

Four shared rule cards are always in play — public, and they affect everyone. "Giants deal +600 total damage." "Knights crush the attacker's attribute multiplier to 1." "Phantom tiles count as 3 base when used in a set." Rules target branches and attributes, not sides. Drew a rule that counters your own roster? Swap it out — or turn it against your opponents.

95 Items

Rule-type items go on the board and rewrite the match. Effect-type items fire immediately. Heal to full, seal an opponent's skills, pull a tile from the discard pile, peek at someone's hand, steal their item, or gamble for +2000 on your next attack (or lose 1000 of your own HP). Items drop randomly when you draw on your turn — whether and when to use them is the call you have to make.
