Have all the guys sit on the floor and make a knot as best they can by crossing arms and legs. Once the guys are ready the girls have 5-10 minutes (depending on group size) to pull the guys apart. The only rules are that you cannot inflict pain and a guy must be completely removed from the "knot" to be considered out. So if he has one hand or foot still in the knot he is still in. The best part of this game is watching the girls when they touch a sweaty boys arm or leg, because the guys will sweat a lot being that close to each other and holding on for dear life. Actually the girls in our group request this game every lock-in we have and every trip we go on. It is a GREAT ice breaker to get new kids involved! Just make sure you are on carpet or a well padded floor.
