The pachislot title Mahjong Story 3: Ultimate Battle of Yakuman Chaos has been added to SloPachi Spirit, a 3D virtual hall simulator app, and is now available to download.
The Mahjong Story series has captivated fans since its first pachinko machine launched in 1991. Among the lineup, Mahjong Story 3: Ultimate Battle of Yakuman Chaos gained particular acclaim for its nine different bonus-trigger mechanisms and went on to dominate arcades across Japan. The title has now been faithfully reproduced within the SloPachi Spirit app.
Players can enjoy mahjong battles featuring the Kazakami sisters and other beloved characters, along with the high-output AT gameplay — delivering approximately +2.9 coins per spin. A dedicated in-app hall has also been created for this title, letting players enjoy an immersive 3D experience that closely mirrors the feel of the real machine.



The machine-specific app can be downloaded from the links below. Note that linked play within SloPachi Spirit requires the main SloPachi Spirit Hall App to be installed separately.
