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. There are still three cheating skills that will make your dream of becoming a mahjong master come true~
