In order to reach the Good Vibration of Shangri-La, Hacker chooses the stairs with bigger steps, and the CyberSquad must choose the stairs with smaller steps. Both sets of stairs grow at a steady rate: the smaller steps double in number each time they grow, while the bigger steps increase in number by one each time. The CyberSquad members were initially worried that they would not be able to catch up to Hacker, but they end up reaching the Good Vibrations before him.
