This is a fun game that's not hard and easy for a group of almost any size.
How to play:
Everyone sits in a circle. There is one person who is "it." There is an imaginary sign being passed around the circle. The person in the middle hast to catch the person who "has" the sign.
Everyone has their own "sign." These signs can be simple or complicated, like a thumbs up or scraching your ear or something like that.
The person who starts with the sign can pass it by doing another person's sign. The other person has to respond with his own sign to receive the "sign." This continues around the circle until the person in the middle figures out who has the sign.
It sounds complicated but it really isn't and it's lots of fun to play!!!
