What is 麻雀鬼巧?

麻雀鬼巧 is a native macOS Japanese mahjong game that lets you play four-player matches against computer opponents. It is designed for players who want solo practice, casual play, or a convenient way to enjoy mahjong without joining an online table. The game includes built-in help for rules and yaku, warning displays for situations such as furiten or having no valid hand, and detailed score calculation so results are easier to understand. Players can choose different match lengths, adjust options such as kuitan and red fives, and review personal play statistics like win rate, riichi rate, call rate, and deal-in rate. Voice readouts and configurable computer player presentation add to the tabletop-style experience. Published by Nutractor, the app is part of the publisher's mahjong lineup and is available for macOS alongside versions on other platforms.

Safety overview

Status: Mostly safe

This is a standard desktop game, so the main considerations are gameplay preferences, in-app settings, and any save data you want to keep. Routine network access for updates, store features, or privacy information is ordinary for a modern app. Removing it should mainly affect the game itself and may also remove local settings or progress if you delete its related support files.

Recommendation: Keep 麻雀鬼巧 if you play Japanese mahjong on your Mac or want an offline AI practice game. If you no longer use it, removing the app is usually fine; just keep any related data first if you want to preserve preferences or progress.
