Overview

About this game

This single-player Japanese Mahjong game offers flexible battle modes, allowing you to freely choose between intense 2-player showdowns, strategic 3-player matches, or lively 4-player games. The game strictly uses a standard 136-tile deck, including numerical tiles (Man, Pin, Sou), and honor tiles (East, South, West, North, Red Dragon, Green Dragon, White Dragon).

Staying true to classic Japanese Mahjong rules, it requires a minimum of 1 han (fan) to declare a win, featuring over 50 yaku (winning patterns) such as Riichi (declaring a ready hand while concealed), Pinfu (a simple hand with no honor tiles), and Chinisu (all tiles of one suit). Riichi must be declared in a closed hand (no melds), adding challenge and excitement; Pinfu requires a hand of sequences and a pair with no honor tiles; Chinisu focuses on a single suit, offering diverse strategies for winning.

Additionally, the game includes an automatic scoring system that accurately calculates points based on han and fu (value units), simulating real-world matches. Enjoy the strategic depth and fun of Japanese Mahjong anytime, anywhere—no internet needed—perfect for solo play.
