1. A topic is given and the object is to reach thirteen things that fit the topic. (e.g.: Topic = Tom Hanks Movies: 1. "Forest Gump"; 2. "The Terminal"; and so on.)

2. Players take turns alternating with other players adding ONE ANSWER AT A TIME to the end of the list after CUTTING AND PASTING THE ENTIRE LIST for the current topic into their post. Players may not add consecutive answers by replying to one of their own posts.

3. The player adding the thirteenth item creates the next topic and adds the first answer.

4. The player adding the second item changes the subject line to reflect the new topic.
