Oh my god. I never get anything like the runs of luck the computer gets! 5 6's one go, followed by a 1500 free roll and then 500 scored in the free roll go!
For level 31, On the right stick, nick a bit off the top left. As it swings around cut it in two so that it nudges the ball. Then on the stick on the left, cut a little nick from the top right so it swings down and knocks the ball in. :)
Finally! 3 days. I found the best method was to keep restarting the first run until you get a score of about 1500+, then buy as many e-rockets as possible and spend the rest on height and band. If you don't get 1500, hit restart near the bottom. :)
