Tenhou English UI

The Tenhou English UI extension translates the interface of the Tenhou HTML5 web client from Japanese to English, making the popular mahjong platform accessible to non-Japanese speakers. It also supports additional languages including French, Vietnamese, Polish, and Spanish, allowing players to enjoy the game in their preferred language. Beyond translation, the extension offers customizable tile sets: you can choose tiles labeled with Western numbers and letters for easier recognition, or opt for brighter colors to improve visibility during gameplay.

Features

• Full UI translation for Tenhou HTML5 clients (versions 3 and 4) and Ron2 (version 3), covering menus, buttons, and game text.
• Support for five languages: English, Français, Tiếng Việt, Polski, Español. Select your language from the extension options.
• Custom tile sets: Western-style tiles with numbers and letters for quick identification, and high-contrast tiles with vivid colors for better readability in fast-paced games.
• Works on the latest HTML5 versions of Tenhou and Ron2. Note that the Flash client is not supported.
• Easy to use: simply install the extension and navigate to https://tenhou.net/3/ or https://tenhou.net/4/ or https://ron2.jp/3 to see the translated interface.

This extension is the latest iteration of the original plugin created by Mai, with contributions from translators and UX designers. It is actively maintained to ensure compatibility with client updates.
