Duolingo is not a game, but a place to learn a new language. It is pretty fun because the design makes it look colorful and the format to learn is not very hard. Duolingo is educational, but you have to know the basics of each language you are going to take. After time, it will teach you some of the language. It is a good idea to learn a new language, but some of the very beginner words need to be taught by a teacher or a different program because Duolingo does not go in depth on the very basics.
