@ Locomikey666 Study some physics. This is nothing more than the transfer of gravitational potential energy, to kinetic energy. If you draw your slopes correctly, you should be able to achieve 70km/h. I got all the badges in less than 5 minutes. It is not impossible.
@anthelion, please explain how you can possibly lose to someone who only clicks the intercept button. I don't see how people can abuse it and get into the "big leagues". I also don't see how this awful "technique" can annoy the opponent. If anything the opponent will find your pathetic repeated interceptions humorous, and defeat your party in 5 turns.
