A fun party game I've seen is similar: everyone sits in a circle, then we try to count to 100 collectively. The catch: if two people say a number at the same time, we have to start over. This is surprisingly fun, at least with a large group. Of course it is easy to game (just count sequentially), but if people are playing for fun, it's really interesting.
