A lot of guessing games - for example hangman - aren't really speaking games but vocabulary games. Here's one which involves the students in a slightly longer speaking turn.

Ask students to describe one of the rooms in their house without naming it - the others have to guess which room it is. Give an example yourself before you start, trying to keep the most obvious information until the end. For example :
This is a room which I like very much because it's full of plants. It's not very big, but it's very cosy. There's a grey carpet on the floor, which sounds boring, but the other main colour - for the curtains, the cushions and the tablecloth - is orange, so it's really quite bright. This is the room in the house where I usually have my breakfast. I like to sit on the sofa and watch the morning news while I have a cup of tea and eat my cornflakes.
Obviously, this is for intermediate students. For beginners you'd need to simplify it.
