About this game

■Free Trial Points Offer
Download the app and register now to receive free trial points.

■Popular Online Mahjong with 1.8 Million Members
Maru-Jan, a popular online mahjong game with approximately 8,000 players daily, from beginners to advanced players, is now available on Google Play.

For online mahjong enjoyment, choose Maru-Jan for its short waiting times.

To provide a more comfortable gaming experience, discarded tiles on smartphones and tablets are approximately 1.3 times larger, and hand tiles on smartphones are approximately 1.26 times larger.

■Challenging the "Realism" of Mahjong
(1) The texture of the mahjong tiles is just like the real thing
Transparency, light reflection, and light transmission are all meticulously finished by hand.

(2) Even the arrangement of tiles is reproduced
Enjoy the realistic feeling of playing tiles, such as the slight misalignment of discarded tiles.

(3) In addition to automatic tile arrangement, "manual tile arrangement" is also employed.
You can also manually arrange your hand of tiles. You can play while paying attention to the arrangement of the tiles.

(4) Research on fully automatic mahjong tables
We simulated fully automatic mahjong tables to reproduce tile distribution.
By using a program that shuffles two sets of tiles on the server, the distribution of tiles from the previous two rounds slightly influences the next round.

(5) Sounds recorded from real equipment
Enjoy "realistic sounds," from the sound of tiles and scoring sticks clashing to the sound of the table operating.

(6) Simple presentation
Without flashy effects, you can concentrate on the game.

(7) A serious competition only possible with a paid service
You pay a table fee, but if you come in first place, the game is free, allowing you to enjoy a tense and exciting match.

Please enjoy the "realism" that Maru-Jan has meticulously crafted.

■ Mahjong AI "KIRIN"
The AI ​​analyzes game records, quantifies various aspects, and suggests optimal moves.
For AI learning, only data from top-class mahjong players (the top 0.008%) with an average ranking of 2.30 or lower out of 1.8 million Maru-Jan members is used.

■ Customize to Your Liking
Multiple table mats and voice options are available for use during matches.
Enjoy your matches with your preferred customization.

■ Web Game Record Function
Review and study your matches without launching the app.

■ Secure Calling Specification Without Revealing Your Hand
Introducing the first-ever calling specification function in a mahjong app: 1-call, 2-call, and red tile-only calling options.
By utilizing calling specification, only the buttons for the tiles you want to call will be displayed, allowing you to play without revealing your hand.

■ "Set Table" for Playing with Friends
We've introduced a set table feature where you can invite others to play together.

Playing at a set table allows you to record the scores of all participants, so you can enjoy it like hosting a mahjong tournament from the comfort of your home.

■ Diverse Events Held Daily
Maru-Jan offers a wide variety of events. From events held on specific days of the week to large-scale events held several times a year, we host events regularly.
Maru-Jan's diverse events, which are free to participate in, are always popular with a wide range of customers, from beginners to advanced players. Event information will be announced in the app as it becomes available.
This online mahjong platform boasts 1.8 million members and is bustling with activity. It offers authentic mahjong enjoyment for players of all skill levels, from beginners to experts. Free events are also held regularly.

It's my cozy little mahjong theme park! No matter what skill level you are, this app will help you improve. So many more ways to enjoy playing riichi mahjong than just mindlessly grinding a last place avoidance ladder. There's always something going on! It would be perfect if there were an English version of the app and website, especially the parts of the site about improving your ability, but you can enjoy all of the features with a little bit of memorization and machine translation.

麻雀ゲーに見せかけた課金ゲーです。 無課金でも勝てばポイントが貰えるので、課金しなくても遊べますが、それではもちろん企業も儲からないので、無課金のユーザーには驚くくらい有効牌が入りません。 東風戦で、ずっとツモ切り、ひとメンツも完成せずなんてこともありましたw お前がヘタなんだろ?と感じるかもしれませんが、それでも驚くことに捨て牌を見たところで、ムダヅモなしでした。 また一打目の捨て牌からど真ん中切ってくるような初心者ユーザーが有段者だったりと、どんだけ課金したんだろうと思います。 (半荘で何度か初手ど真ん中やってきたので、初心者でしょうね…) このゲームのアルゴリズムは局が始まった瞬間に勝つプレイヤーが決まってる仕組みなのかな。 売りの賞金のある大会も決勝にしっかりプロの方が残るのを見ると運ゲーというより見えない力が働くゲームだなと感じました。 これだけAIなどが進んでも、なんで麻雀ゲームのアルゴリズムって進化しないんでしょうね? 手積みなり全自動卓で打ってるようなアナログ感ある、麻雀ゲームってあったら教えて欲しいです。

手積みまたは自動卓の感覚で楽しめます。仕組まれたプログラムのような作為を感じません。
