A match inside a cage of steel walls surrounding the ring. You win by pinfall, submission, or escaping the cage (over the top or through the door). The original gimmick match — designed to keep interference out and settle feuds definitively. The cage wall adds its own offense: getting thrown into the mesh, getting your face grated against it, climbing to the top and deciding whether to escape or jump. The escape finish is either genius or stupid depending on who you ask.
"He's at the top of the cage! Does he escape and win or does he jump off and go for the spectacular finish? He jumped. He always jumps."
