Instruct your whole group to walk randomly around the room. About every 10 seconds or so, call out a number. Everyone in the game must immediately form a group hug made up of the number of people that you called.
This sometimes leaves some people unable to form a group because they don’t have enough people. They are out of the game. Repeat until you only have two people left and declare them the winners.
Like musical chairs, play upbeat music between calling out numbers.
