Also not mentioned, there are 4 skillshots on ball launch:
1) go through lit upper lane
2) hit the witch
3) hit the jackpot on the side next to the haunted forest bumpers
4) hit the lit letter of crystal ball.
All of these increase in value as you perform the same skill shot again. Can't remember the values off the top of my head so need to verify these values, but believe that 1 is the lowest starting at 5k, 2 next at 6k, 3 next at 7.5k and finally the crystal ball letter the highest at 10k.
