★★★★★Oct 19, 2026

プレイ中にRTAを使うプレイヤーは多いが、それについて何の反応もない

★★★★★Oct 17, 2026

cada cierto tiempo caigo en una racha de perdidas de la que no puedo salir, bajando incluso de tier, va más allá de la suerte de uno porque cómo es posible que incluso teniendo una buena mano desde el inicio curiosamente el contrincante tiene una mejor y de paso a uno mismo le sale la winning tile justo para dársela al contrincante. Llevo 3 semanas en rachas de partidas perdidas, ya me había pasado antes también y algo me dice que el juego está pensado optimizado para hacerte pasar por esto.

★★★★★Oct 12, 2026

麻雀を楽しむ環境として非常に優れており、ガチャも無課金プレイヤーにとても良心的です。コラボも定期的に開催されていて、飽きることなく楽しめます。 そして何より、Discordやメールを通じた運営のサポートが本当に素晴らしいです。対応も丁寧で、安心してプレイできる点も大きな魅力だと思います。 リーチ麻雀を楽しみたい方には、ぜひおすすめしたいクライアントです。

★★★★★Sep 29, 2026

d is the, but I dr 3am to see if 7pm will get 7am for BP or if it works 43, if

★★★★★Sep 18, 2026

Nothing can convince me the game isn't rigged. Not even the devs own words. The only time i had advantage is when others use the default characters. The moment they have limited skins, animation, etc. They suddenly have massive luck. Constant ippatsu, early Riichis, and gets Ron at every weirdest times. If i could give negative star review, this would probably be the first game I'd give it to.

★★★★★Sep 15, 2026

Tutorials are extremely helpful. There's very expensive gacha, but it's mostly cosmetics. you can play as much as you want. You can play on mobile and PC using the same account and progress.
