A group of people perferably at least 5 sit around a room either standing or sitting. They each take a turn counting off a number 22.214.171.124.5... They do this until they reach a number with 7 in it or a mutiple of 7. The person that lands on that number must clap their hands immediately as they sound off on the number Or be disqualified.
the count starts going in the opposite direction around the circle. So the person that sounded off before the 7 or multiple of 7 was said would go again continuing the count.
If disqualified that person can continue to play but must drink pre determined number of drinks usually 7.
its extremely fun to see how people after awhile can not remember simple arithmetic.
