After passing through the checkpoint, which can cause delays, travelers are moved toward the opponents buildings to locate his "Master Plan". When found, the "Master Plan" is rushed back through a checkpoint or "Over the Wall".
This was a gift to my sister. She bought this same game for my twin daughters when they were young. We all loved playing it. I don't remember what happened to the one my sister bought, but she never forgot playing it with us. She loved this game. When we got together recently, she mentioned this game again. Unknown to her, I looked it up online and ordered it. It arrived the day before I left to come home. A niece visited her recently and they played this game over and over and had a blast. Best gift I've given anyone in years.
While this is a children's game we played it at a women's club gathering. It was sooooo funny I was crying. The next day I went on line and ordered it. Just make sure that you don't play this in a location where there are a number of other quiet people.
