Playboard

Professional puppeteers hang their puppets upside down from a ring on the playboard shelf inside the puppet theater and slip the puppets on like gloves. […] When the puppet is removed, it is hung back in its place on the playboard.

Nothing moves on these playboards except the ball itself which rolls down the inclined playboard by gravitational pull.

Playing pinball requires total concentration, the right combination of skill and chance, a mastery of indeterminacy as the ball moves across the playboard and interacts with bumpers and cushions.
