The playing surface of a pinball machine. Usually made of wood that has been painted and shellacked and waxed, though many modern machines use a diamondcoat process to ensure a long-lasting, smooth surface. Often has plastic inserts to show lights through the surface. Everything else inside the playing area is mounted to the playfield directly or indirectly.

Some games have a mini-playfield mounted above or, rarely, below the regular playfield which may only be used for certain special modes, or may be a major part of the game.
