As the hero Jack, the player must jump and work their way through 16 multi-room levels picking up bombs for points, treasure, and avoiding enemies (skulls, mummies, insects, birds, etc.) while getting to the end of the level. Jack has no means of attack, but fortunately has jumps that reach the entire height of the room, and can control and stop/redirect jumps with ease by hitting the jump button in mid-air to stop and float more slowly down.
