The roguelike built on real mahjong

Jahmong is a single-player roguelike built on real, classical mahjong: the family-table game played for over a century. Draw and discard toward melds, call pongs, chows, and kongs, and declare hu. Between hands, a shop sells flowers that bend the rules until the scoring breaks.

Real mahjong, really taught

Never played mahjong? Perfect. Melds are just sets and runs. If you've ever played rummy or poker, you already know the bones of it. Jahmong teaches you the rest while you play: your first scored hand comes in minutes, and by the time you beat the East wind, you'll know real mahjong for life.

Choose your flowers

In traditional mahjong, flowers are bonus tiles: pure luck of the draw. In Jahmong, you choose them. Every flower changes how hands are scored, triggering off your pongs, chows, kongs, and hus. Stack them into one-suit purity builds, pong engines, or kong economies, add consumable tiles and shop rerolls. Where other games leave luck to the draw, Jahmong lets you pick it, and push the scoring further than mahjong has ever gone.

Four winds. Four bosses.

Sixteen rounds across East, South, West, and North. Score targets climb every round, and each wind ends in a boss that punishes exactly the way you've been winning. A full run takes about half an hour. One more run is always a lunch break away.

Break the scoring

Chain calls into cascading multipliers and watch a target of 200 fall to a hand worth 8,800. Every win ends with a score card worth showing off, and every loss ends one tile short of a story.

Crafted, not generated

A bold, geometric table where every piece earns its place. Every tile clack recorded from real mahjong tiles. An original score composed by the developer. No real-money gambling, no gacha, no fan-service. This is the mahjong game you can play with your whole family
