u want to focus on perfect jumps, landing as close to the front of the next rail as possible. U will know when u did it, balloons pop up and it says perfect jump,
Hahahaha - Yes i got SUPER lucky on 15, actually 16 was the hardest one so far now i am at 20 and have no idea how to kill the sucker......good luck.....to be honest follow a strategy of course u will lose because its not fair but stick with ur strategies and u will eventual get the luck u need....
to get the Necronomiconquerer Badge - focus on what u need. If ur low heath boost heath first, and always boost arcane too, then attack....its all about luck but think about it and u will win, trust me, I got challenge 15 in the 4th try, the cpu will not always attack, if they get hurt on heath they will want to address that then win....
