MAHJONG: BEYOND THE WALL 天井之外

Mahjong tiles. Roguelike engine. Score explosions.
Mahjong: Beyond the Wall is a roguelike deckbuilder where Mahjong tiles replace playing cards.
You are not playing traditional Mahjong.
Instead, you pick any 5 tiles from your hand, trigger scoring patterns, and stack relic effects to build a runaway scoring engine.
Watch the calculation unfold:
BASE × TYPE × MOMENTUM × ENGINE
Multipliers climb higher and higher until the numbers explode.
Core Gameplay
• Draw a hand of tiles
• Pick any 5 tiles to play
• Trigger tile patterns (Triplet, Sequence, Flush, Honor builds...)
• Stack relic effects to multiply your score
• Beat escalating blinds and bosses
• Push your engine to ridiculous multipliers
A single run can take your score from hundreds to billions.
