What is Wittgenstein's theory of language games and how can I use it in a question?

Wittgenstein's theory is that language is like a game: you can only get involved if you know the rules of the game. In the same way that you could only play chess if you knew how each piece could be moved, you can only use language if you understand the meaning assigned to each word. Words have hidden connotations so that we can only understand the meaning of a sentence if we are playing the right 'game'. This is useful in your religious language unit as a way of undermining scientific criticisms of religious statements - the scientists are not playing the same game and so misinterpret the statement 'Jesus rose from the dead'. They read it as a scientific truth claim which goes against all prior experience and thus seems completely unfounded. However a religious person understands that the real meaning of this sentence is to convey the promise of eternal life, salvation, opportunity of redemption through Jesus Christ and so on.
