Participants sit on chairs in a circle. One chair is free. The one on the left of this chair has to call someone to sit on this chair by saying: “I am calling Adam to sit on this chair because he has blue shoes, the same color as I do.” or “I am calling Anna to sit on this chair because she is wearing glasses, and I’m wearing them too.”, etc. The participant who now has a free chair on the left side of him/her has to call another participant to sit on that chair, and so on. Every participant has to switch places once.
