This depends on the kind of party you mean. In the U.S., there are different kinds of parties usually depending on whether people are drinking alcohol. There are many different drinking games in the U.S., often using a deck of cards. One game I play a lot with my friends is called "King's Cup." Beer pong is also a popular drinking game. There are also different board games people can play at a party (with or without alcohol) such as Apples to Apples, Scattergories, Monopoly, etc. In my experience, however, games seem to be a much more prominent part of Chinese parties than in American parties. Hope this helps!
