For this game, all you need is a pool noodle or a pillow... something that won't hurt if you got hit with it!
Have your group sit in a circle on chairs.
One person stands in the middle with the pillow or pool noodle and picks one person.
That person then says their name and the name of someone else in the circle. Then that person says their own name and the name of someone else. This continues, and whilst it's happening, the person in the middle is trying to hit the person whose name was said before they can say the name of someone else.
If they hit the person before a new name is said the person who was hit becomes the person in the middle and the person who was in the middle takes that person's seat.
This is a great game to learn the names of people in your group!
