■ Popular Online Mahjong with 1.6 Million Members

■ Challenging "Authentic" Mahjong

(1) Mahjong Tiles with a Realistic Texture

Every detail is meticulously hand-finished, including transparency, light reflection, and transmission.

(2) Authentic Tile Arrangement

Experience a realistic feel, with details like slightly misaligned discarded tiles when you make your move.

(3) Featuring Both Automatic and "Manual" Tile Arrangement

You can choose to arrange tiles manually, allowing you to pay close attention to their alignment.

(4) Research on Fully Automatic Tables

We simulate a fully automatic table to replicate the natural bias in tile distribution.

Using a program that mixes two tile sets on the server, the tile distribution from the previous two games subtly influences the next game.

(5) Sounds Recorded from Real Games

Immerse yourself in authentic sounds, from tiles and sticks clacking together to the hum of the table.

(6) Streamlined Game Production

The game avoids flashy effects, letting you concentrate fully on your strategy.

(7) Serious Competition in Paid Games

While a table fee applies, finishing in 1st place makes it free, creating a uniquely tense and rewarding match.

Please enjoy the "authentic" experience that Maru-Jan meticulously crafts.

■ Mahjong AI "KIRIN"

The AI analyzes your hand and score, providing various metrics and suggesting optimal discards.

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

■ Customize to Your Taste

We offer several table mats and in-game voice options.

Enjoy the game with your preferred customization settings.

■ Web Review Function

You can review past games and study strategies without needing to launch the app.

■ Secure Call Specifications to Protect Your Hand

Maru-Jan is the first mahjong app to introduce specific call functions for 1st, 2nd, and red tile calls.

By utilizing these call options, buttons only appear for tiles you wish to call, allowing you to play without revealing your strategy.

■ "Set Tables" for Playing with Friends

We have introduced Set Tables where you can invite specific players and enjoy games together.

Games at Set Tables record results for all participants, letting you host a mahjong tournament from the comfort of your home.

Various Daily Events

Maru-Jan is packed with events, from daily weekday events to large-scale tournaments held several times a year.

Maru-Jan's diverse free events are consistently popular with a wide range of players. Event information is regularly announced within the app.
