 In these versions, Jack is renamed Leaping Lenny.Each level consists of a set of eight wraparound floors, across which holes scroll; when these holes reach the side of the screen, they move up or down to the next floor, depending on if they're scrolling to the left or right, respectively.The goal in each level is to reach the top, by jumping through the holes; however, each time Jack jumps, a new hole is formed on a randomly chosen floor.
