About This Game

Lie, cheat, and steal your way to victory in Dirtbag Mahjong!

Choose your character and join five other dirtbags for a night of riichi mahjong and misdemeanor assault. Nobody here plays fair, and they've all got some dirty tricks up their sleeves.

Dirtbag Mahjong is a complete and beginner-friendly mahjong experience that also offers some party game surprises to keep experienced players guessing.

Features:

  • A full riichi mahjong text guide and interactive tutorial, to help ease beginners into the game or the higher difficulties

  • Six playable characters with unique abilities, each with their own story mode

  • Free play mode with both "standard" or "dirtbag" rules, for a complete single-player mahjong experience

  • CPU difficulty options ranging from beginner-friendly to unfairly hard

  • Skins for tiles and characters

  • Hand drawn pixel art

  • Full gamepad support

Demo features:

  • The full riichi mahjong text guide, and the first two chapters of the interactive tutorial to get beginners started

  • A preview of Vren's first playable story chapter

  • Dirtbag mode free play with a random character

  • Normal mode free play with full choice of character

The demo is not limited-time, but there is a restriction in how many full East games you can play before it ends, since the free play mode covers a significant amount of the game.
