Participants sit in their chairs in a circle. The person who feels the fastest that day will be the "breakwater". That person stands up and stands in the center of the circle. The breakwater wants to sit on the empty chair, but the others slide towards the empty chair to block him. There is always an empty chair, but it is instantly filled by the wave sliding towards the empty chair. If the wave-swimmer finds a chair to sit on, the person who cannot fill it and remains standing becomes the new wave-swimmer. Once the game has been mastered by everyone, the wave breaker can determine which way the participants will slide by saying "right" or "left".
