According to INSIDE and GAME Watch, the game supports both smartphones and PC and lets players compete against others across Japan. INSIDE lists the platforms as iOS, Android, Windows and browsers. The game includes a "beginner assist function"; 4Gamer.net reported that it suggests possible winning hands and recommended discards. It also features voice lines recorded for the game and stamps for communicating during matches. [ 1 , 2 , 3 ]
4Gamer.net reported that players can choose a favourite talent to play alongside and customise the player, riichi effects, tiles and table one by one. According to the outlet, there are four modes: online "Ranked Match" and "Tournament" against players nationwide, a "Single Mode" played at one's own pace, and a "Friend Match" for playing with friends.

Players can pre-register through the App Store, Google Play and by following the official X account, which opened on October 9. Rewards depend on the number of registrations: social media icons and mahjong table skins at 100,000, 200,000 and 300,000 registrations. At the top tier, a mahjong-magazine-style notebook will be given by lottery to followers of the official X account. GAME Watch reported that official accounts on X, YouTube, TikTok and Discord have opened and that a game trailer has been released on the YouTube channel. [ 1 , 2 , 3 ]
A special livestream is scheduled for October 13 from 20:00 with Roboco (ロボ子さん), Shirakami Fubuki (白上フブキ), Ookami Mio (大神ミオ) and Houshou Marine (宝鐘マリン). It will cover the game's features and the latest news, along with variety segments. [ 1 , 2 , 3 ]
