Place the cup of beer in the middle of the table and whoever has the quarter(s) starts. The object of the game is to try to make it in the cup before the other person with the quarter does. If you have two quarters, slide one quarter to person of choice then shoot. On missed shots, the quarter is up for grabs. When someone makes it, whoever has the other quarter has to drink. If the someone doesn't notice that the other quarter is in their "zone" they still have to drink. Whoever's "zone" the quarter is in they have to drink...even if they're not paying attention. This gets fun as people get drunk and don't pay attention.
