■ Experience "Authentic" Mahjong

(1) The mahjong tile texture feels incredibly real.

Every detail, from transparency to light reflection and transmission, is meticulously handcrafted.

(2) Realistic tile arrangement is reproduced

Enjoy the realistic sensation of playing, including the natural misalignment of discarded tiles.

(3) Featuring both automatic and "manual" tile arrangement

You can also arrange the tiles manually, paying close attention to their alignment as you play.

(4) Research on fully automatic tables

A simulation of a fully automatic table reproduces natural tile bias.

Using a server program that mixes two tile sets, the distribution from the previous two games slightly influences the next game's tiles.

(5) Sounds recorded from real gameplay

Immerse yourself in authentic sounds of tiles clacking, sticks hitting, and the table in motion.

(6) Simple, focused production

The clean, non-flashy design lets you concentrate fully on the game.

(7) Competitive gameplay unique to paid matches

A table fee applies, but finishing in 1st place makes it free, adding thrilling tension to every match.

Discover the "authentic" quality that defines Maru-Jan.

■ Mahjong AI "KIRIN"

The AI analyzes tile scores and suggests various statistics and optimal discards.

For training, the AI exclusively uses data from top-tier players—the top 0.008% of Maru-Jan's 1.6 million members with an average finish of 2.30 or better.
