The Lost Worlds books are combat gamebooks, as opposed to story gamebooks. The different pages of each booklet show the character performing combat maneuvers. Two players each trade booklets, and simultaneously call out maneuver numbers, which are then cross-referenced to determine which page each player turns to, and whether each character's attack succeeds.
