[Recommended points]Super popular mahjong game!

game system

Although this game requires payment elements by purchasing points, you can play the game without paying any monthly fees, membership fees, registration fees, annual fees, etc.

Players enter the waiting room during a match, and once there are enough players available, players can play on a first-come, first-served basis.

Battle screen

One Dongfeng game costs 80 points, and one Tonan game costs 150 points. You can purchase from 1000 points (1100 yen).

You will not be automatically charged after the “first time free points” mentioned above run out, so you can play the game with confidence.

lobby

There are two types of lobby: “Normal” and “Royal”. The condition for entering the Royal Lobby is to have a certain number of points.

lobby screen

In the Royal Lobby, where you compete for points in a serious competition, if you win first place you will earn points that exceed the game fee.

Even if you are in 4th place, the points you pay will be based on the entry conditions of each table, so you can take on the battle with confidence.

Operation system

When playing on the PC version, it is useful to remember the various shortcut keys assigned to the keyboard.

You can switch between “with squeal” and “no squeal” with a shortcut key. You can also “specify the sound” here.

Operation screen explanation

The key point is that the corresponding key bindings are also displayed on the operation buttons, so you can play without hesitation even when you see it for the first time.

With the mouse, you can play tiles by left-clicking twice, and you can cut tiles, specify squeals, and cancel buttons by right-clicking.

Mahjong AI “KIRIN”

A groundbreaking system that uses AI technology to perform analysis and instruct players on recommended actions.

Mahjong AI KIRIN

20 points are consumed for analysis. This is a service that can be used for deciphering and analyzing tile music.

Sparrow money

In addition to points, the game also has an in-game currency called “Japanese coins.'' Points are awarded based on specific progress, events, and point purchases.

Sparrow money

Sparrow coins can be used as participation fees in the Pro League and Tenjo Tournament, and can also be used to purchase items at the store.

dan system

Ranks start at 20th grade and increase based on the “Jakuryoku” accumulated according to the results of the battles. Those of level 7 and above are considered to be “true strongmen.''

If you reach grade 10 or above, you may be demoted depending on your results. This should increase your motivation for the fight.

Dan system explanation image

This game has a rating system and flag system to visualize the strength of the players, allowing you to visually enjoy the world of mahjong.

This is a work that I can highly recommend from a visual standpoint.

[Recommended points]Easy to understand system!

mahjong six tactics

“Mahjong Roku Tactics'' is a system in which when you play 50 Shima games or 50 Sanma games, you are assigned an “animal'' that becomes your alter ego depending on your attack, defense, and strategic tendencies.

Image of Mahjong Roku Tactics

It's interesting that animals are assigned according to style, such as “horse'' if you have a tactical eye that doesn't swing, and “eagle'' if you have a style that allows you to reach and mow down big game.

By looking at the opponent player's animals, you can predict how they will hit to some extent, which is useful.

[Recommended points]Interesting system!

customization

At the “Maru-Jan Store,'' which can be accessed from within the game, you can purchase various items by spending badai points and mahjong coins.

The “table mat'' that is reflected on the play screen has various designs that will refresh your mood.

You can also switch “Voice” on My Page. There are a total of 8 variations of male and female voices, so you can change it depending on your mood that day.
