Set up the four shot glasses on the other end of the table in a row so that it forms a line going away from you (the home base where you will be shooting from across the table). Each player on the visiting team takes turns shooting the quarter at the shot glasses. The first glass represents a single, the second a double, the third a triple, and the last a home run. Three strikes (misses of all shot glasses) and you are out. Three outs and the other team is up to bat.
The game follows as regular baseball and runs are scored in the same way (except that you have to keep track of the runners on base in your head). Drinking happens in the following manner:
For example, if they hits a single, they must drink the remaining three shot glasses full of beer. If they hits a triple, they only have to drink one. If they gets an out, they must drink all four.
This game is pretty simple but lots of fun (and lots of drinks)!
