I've successfully added comprehensive multi-language support to the Emoji Sudoku website with Japanese, Korean, Spanish, and English translations. The language selector appears in the header with clean button styling that matches the black and white theme. All content including the privacy policy, terms and conditions, navigation, and main content is now fully translated and switches dynamically when users select a different language.

I've updated the "Play Now" button to link directly to the Apple App Store URL you provided. The button now opens the Sudemoji app page in a new tab when clicked, maintaining the same visual styling while providing the proper functionality to download the actual game.
