Spanish language learning forums - What do you use to learn new words in fun way?

Hello everyone!
I've been learning English and Spanish for several years now, and I'm always looking for fun ways to keep it interesting.
Like many of you, I also use Duolingo — I really enjoy it. The exercises feel like mini-games: short, clear, but still feel like stydying(
Recently my bf, showed me a few simple games for my iphone with intension to word-learning. Some of them look like flashcards, but more relaxing. It feels like one of these match3 or other puzzle games, you just play.
So I have a question, what do you use to continue learning language when you are tired of studing and just want to have fun? Hope I've clearly explained my question, lol
