All players are running in ever-changing directions. Several chasers are identified by scarfs or bibs etc.
Players are immune from being tagged if joined with another (friends) and springing in a circle. Instructor declares beforehand how friends are joined: side by side, facing each other, or back to back.
On the instructor’s frequent signal (clap), all pairs (friends) must disengage, and for new friendships (pairs)
If caught by a chaser, chaser and player change positions.
