About Demonic Mahjong
Demonic Mahjong is a roguelike deckbuilding game built around Mahjong tile combinations. You use the tiles in your hand to score under basic Mahjong rules, develop strategies and defeat bosses. You can play without knowing Mahjong, though familiarity with its rules gives you a head start.
Build your strategy
You can shape your approach with spirit allies, relics, offerings and tile enhancements:
- Spirit allies: 100 allies can support distinctive strategies or change your core gameplay.
- Relics: 100 relics provide powerful buffs and permanent growth throughout your journey.
- Offerings: 35 offerings grant special abilities to manipulate your hand or deck and improve your luck.
- Tile enhancements: 17 tile spirits and 12 tile variants add effects to your Mahjong tiles.
Each character has an active skill and a passive skill. You build tile combinations around these skills to create different strategies and gameplay styles, and can upgrade each character's skill levels.
Choose your path
As you travel deeper into the underworld, you choose where to go and encounter events such as having Forgetful Tea at Granny Meng’s Tea House or helping a shy ghost with a request. There are 10 regular events and 90 special events, and your actions and choices can significantly affect subsequent battles.
Face the bosses
Each underworld journey brings you up against 24 unique bosses, including Granny Meng, Ox-Head and Horse-Face, and the Four Judges. Every boss has active and passive skills to learn and counter. Special animations play whether you defeat a boss or lose to one.
