Demonic Mahjong is a Roguelike deckbuilding game inspired by the timeless mechanics of Mahjong. Masterfully use the tiles in your hand to craft powerful combinations, reach staggering high scores, and develop strategies that are uniquely your own! It’s Mahjong, but not just Mahjong: Scoring follows basic Mahjong rules, so if you know how to play Mahjong, you’re already halfway there! Roguelike gameplay is seamlessly integrated into the Mahjong foundation. Find your best strategy to win big! It’s not just about getting high scores; the key is to find a way to defeat the boss! Deep Mahjong Strategy: 100 unique spirit allies, each capable of helping you form distinctive strategies or completely changing your core gameplay. 100 relics provide powerful buffs and permanent growth throughout your journey. 35 offerings grant special abilities, allowing you to manipulate your hand/deck and even improve your "luck." 17 tile spirits and 12 tile variants enhance your Mahjong tiles, enabling you to unleash even more powerful effects. Build Your Ultimate Underworld Team: Each character has their own unique [Active Skill] and [Passive Skill]. Build powerful tile combinations around characters to form unique strategies and core gameplay styles. Every character can upgrade their skill levels, and a character affinity system is also planned! Unique Event System: How about a cup of Forgetful Tea at Granny Meng’s Tea House? Or maybe helping a shy ghost with her request? 10 regular events and 90 special events make every Mahjong journey full of surprises. Your actions and choices in these events will have a significant impact on the subsequent battles. Diverse Boss Battles: Accompanying you on each journey through the underworld are 24 unique bosses, including Granny Meng, Ox-Head and Horse-Face, and the Four Judges. Each boss has their own active and passive skills. Study them to find your path to victory! Whether you lose to them or defeat them, special animations will celebrate the moment!
