The players sit in a circle. Each player places an open beer in front of them and a cap upside down on the beer. The players take turns throwing a cap a someone else's beer. If you knock their cap off, they take a drink. If you knock it off twice in a row, you make up a rule and a consequence for breaking the rule. If you knock it off three times, the person has to chug the beer.You keep going until you miss and it is the next persons turn. You are not allowed to adjust your cap on the beer. If you touch it you must drink. If you knock your own cap off, you must finish your beer.
