The browser version of Lexitaire (play it free at mintyfreshapps.com/lexitaire/web_game/) has been steadily adding languages beyond its original handful. Romanian, Dutch, Indonesian, Swahili, Tagalog, Turkish, Malay, Vietnamese, Russian, Ukrainian, Swedish, Norwegian, and Finnish have all joined over the past couple of weeks, several of them added specifically for reach into markets -- East Africa, the Philippines, Southeast Asia -- that a browser game can reach in a way an app store listing alone can't.
Today's additions, Arabic and Hebrew, are a bigger step: the browser version's first two right-to-left languages. The whole interface mirrors accordingly when you play in either one.
That's 22 languages for the board, letter bag, and dictionary in the browser version. Every one of them has real, sourced dictionary data behind it, not a token gesture: see the Supported Languages page for the full list, or click through to any language's own page for exactly where its word list comes from, its letter distribution, and a few things that make it different from the others (Vietnamese's tone marks needing their own tiles, Turkish's dotted vs. dotless I, and so on).
