C-EGG

C-EGG is a Japanese developer whose sole public Windows offering is Tenhou (天鳳), the online client that connects players to Japan’s most heavily trafficked riichi mahjong network. The lightweight program opens a resizable window onto the service’s HTML5-based tables, letting users compete in the same ranked hanchan and tonpuusen matches that streamers and professional leagues reference when discussing current metas. Beyond standard four-player contests, the client exposes the platform’s full tournament lobby, replays with graphical tile trails, and a spectator mode that overlays real-time statistics such as deal-in rates and shanten counts. Because matches are resolved on remote servers, the local executable focuses on rendering the board, managing websocket traffic, and caching sound and sprite assets so that even modest laptops can display animated tile movements without frame drops. Players who want offline practice can launch the replay analyser to step through any log file frame-by-frame, while those preparing for competitive events use the built-in rating graph to track rank progress across multiple seasons. Optional JIS/XIMES keyboard hooks and gamepad profiles make it straightforward to discard tiles quickly, and the settings pane allows macro-free one-key reach, riichi, and tsumo calls that comply with the network’s anti-automation policies. C-EGG’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always fetch the latest upstream build, and can be queued alongside other applications for unattended batch installation.
