Description

Supplied by the Steam store

A focused game of Riichi Mahjong

Play four-player Japanese Riichi Mahjong on a clean pixel-art table. Practice on your own, invite friends with a room code, and build your understanding one hand at a time.

Practice and play with friends

Local practice against computer opponents with Normal, Expert and Hard difficulty settings.

Four-player riichi rules with red fives, dora, furiten and East/South match results.

Create or join online friend rooms using a room code. Online rooms require an internet connection.

Read your hand, discards, open melds and score details clearly.

Learn at the table

Illustrated lessons and exercises introduce the basics, calls and riichi, common yaku, scoring, tile efficiency and defense. The learning material is available in Chinese and English.

Make the table your own

Choose tile faces and backs, adjust music and ambience, and reduce motion when you prefer. The interface includes 20 languages. Designed for keyboard and mouse.

For entertainment and learning only. No real-money wagering or cash prizes.
