Left click the blue button to defend and hold the position until the blue meter on the left side of the screen is full or almost full. When the blue meter is mostly full repeatedly tap on the screen away from the button to throw a flury of punches at your opponent, then go back to the defensive position until your punch is charged back up. Repeat the process until you win via TKO or KO. This is a JavaScript web application which uses cross-platform mobile-friendly HTML.
