Musical Hoops

You and your classmates will walk around a line of hoops on the ground while music is playing. The number of hoops shall be one less than the number of teams. When the music stops, you must hurry to perform the designated behaviour (sit or down) inside a hoop, on a single verbal or visual cue. If every team inside a hoop successfully performs the behaviour on a single cue, then the team not in a hoop goes out. Any team requiring more than one cue to perform the behaviour goes out, allowing the team outside the hoop one attempt. After each turn, the number of hoops will be adjusted to remain one less than the number of teams. The last team standing wins.
