Jahmong

Mahjong roguelike

Jahmong is a single-player roguelike for PC built around classical mahjong. You draw and discard tiles to form melds, call pongs, chows and kongs, then declare hu to score a hand. The game teaches the rules as you play, starting with sets and runs and working toward scored hands.

Flowers and scoring

Between hands, you can buy flowers from a shop. In traditional mahjong, flowers are bonus tiles drawn by chance; here, each flower changes how hands score. Their effects can trigger from pongs, chows, kongs and hus, so you can build around one-suit purity, pongs or kongs. Consumable tiles and shop rerolls give you more ways to shape a run.
