There are many variations to this game which result in making a sentence or drawing, etc. : at my family Halloween parties we write stories.
Each person gets a notebook and writes the first sentance of a Halloween story and then passes the notebook to the person on the right who adds a sentance to the story. When the notebook goes around the circle, the originator gets to read the completed story to the group. The outcome can be scary or silly depending on the personalities of the writers, but they are seldom predictable and often very entertaining.
