Everybody gets a shot glass and fills it up with beer. Take a quarter and spin it, you drink your beer with your right or left hand, when you finish your shot pick up the quarter with whatever hand you used to drink. Then pass the quarter to the next person. If you used the wrong hand (like you drank with your right and picked up the quarter in your left) you go again.
Landmines come into play when you finish a beer DURING the game. While a person is drinking slam your beer can on the coin and make them go again. The landmine stays on the table and when a coin hits the landmine they have to do it all over again. It's a fun and easy way to get majorly screwed up!!
