Description

From the listing uploaded by “appupdater”.

■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.
