We would count up from 1, going clockwise. When you reach the number 3 or a number divisible by 3, you'd replace that number with the word "buzz" and the flow of the game would reverse directions. When you reached the number 7 or a number divisible by 7, you'd replace the number with word "kill" and again reverse directions. When you reached a number divisible by both 3 and 7, you'd say Buzzkill and reverse directions twice (iow, keep going same direction). If you responded incorrectly or out of rhythm (or direction), you'd have to take a shot and start off the new game.
