If you just pick whatever game pops out, you may either be lucky and that will be a good game, or the complete party becomes a disaster.
There’s only one thing left to take care of: finding the right games. For big parties, we always go with team drinking games, since it gets super-complicated for everyone to play the same games alone, and to be frank, team drinking games are hella fun. In general, there are two main types of drinking games: single-player & team ones. Everyone already knows that we can’t go to a party without drinking games, and we love to admit that! There is a good deal of drinking games, for different numbers of people, with different equipment required, and so on.
