I guess the Russian and German versions of Club Penguin aren’t doing well in comparison to the other languages: they announced today that in several months time they will be closing down the game’s Russian and German variations.
If you go to Club Penguin’s German and Russian website there will be a banner at the top of the website notifying you.
September 2, 2015 is when you can no longer play Club Penguin in Russian or German, and as of today you can no longer make a Club Penguin account in those languages. Don’t worry though, no accounts will be deleted if you joined Club Penguin in Russian or German. You’ll still be able to play Club Penguin in English, French, Portuguese, or Spanish.
Thanks Xpome and Denice!
