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.
