Developer Description
Online mahjong is a popular online game with 1.7 million members. Authentic mahjong that can be enjoyed by everyone from beginners to advanced players. We also hold events from time to time that are free of charge.
All new users who download the app and register will receive free trial points.
■Popular online mahjong with 1.7 million members
The Google Play app version of Maru-Jan, which attracts around 8,000 people every day from beginners to advanced users, is now in operation.
If you want to enjoy mahjong online, try Maru-Jan, which has minimal wait times.
To make the game more comfortable, the discarded tiles on smartphones and tablets have been made approximately 1.3 times larger, and the hand tiles on smartphones have been approximately 1.26 times larger.
■Challenge to “real” mahjong
(1) The texture of the mahjong tiles is just like the real thing.
Every detail is hand-finished, including transparency, light reflection, and light transmission.
(2) Reproduce the arrangement of tiles
You can enjoy the realistic feeling of hitting tiles, such as the discarded tiles shifting slightly.
(3) Adopts not only automatic tiles but also “manual tiles”
It is also possible to manually arrange the tiles in your hand. You can play by paying attention to the arrangement of the tiles.
(4) Research on fully automatic desks
A fully automatic table simulation is performed to reproduce the tile bias.
Due to the program that uses two sets of tiles on the server and mixes them, the distribution of tiles from the previous game and the one before the previous game will slightly affect the next game.
(5)Sound is recorded from the real thing
Enjoy "realistic sounds" including the sounds of tiles and dots hitting each other, and the sound of the table operating.
(6) Keep the production simple
There are no flashy performances, so you can concentrate on the game.
(7) Serious competition unique to paid games
You have to pay for the place, but if you come in first place it's free, so you can enjoy a tense game.
Please enjoy the "realism" that Maru-Jan is particular about.
■Mahjong AI “KIRIN”
AI analyzes the tiles, converts them into various numerical values, and suggests the optimal tiles to play.
For AI learning, we only use data from top-class mahjong players, the top 0.008% of Maru-Jan's 1.7 million members, with an average finishing order of 2.30 or less.
■Customize to your liking
We have prepared multiple table mats and voices for use in games.
Enjoy the game with your favorite customization.
■Web tileset function
You can look back at the game and do research without starting the app.
■Specify the sound so you can rest assured that your tiles will not be revealed
For the first time in a mahjong app, we have introduced a function to specify 1 cry, 2 sounds, and red-only sounds.
By making full use of the squeak designation, the button will be displayed only for the tiles you want to squeak, allowing you to play without revealing the tiles in your hand.
■“Set table” where you can play games with your friends
We have introduced a set table where you can invite people who want to play and play together.
When playing a game at a set table, the results for all participants are saved, so you can enjoy it like holding a mahjong tournament from the comfort of your home.
■Various events held every day
There are many events at Maru-Jan. From events held every day of the week to large-scale events held several times a year, we also hold events from time to time.
Maru-Jan's various events, which are free to participate in, are always popular with many customers, from beginners to experts. Event information will be announced within the app from time to time.
