Skateball pro tip: NEVER SHOOT AT THIS BANK ON PURPOSE 
The bowen tutorial on Skateball is good, I would watch that. I don’t recall anything about the star rollovers and scoring. When I had one (same game that was used at Indisc back in january), I always went for 100k collects and then bonus collects if my misses whiffed enough to give me some solid progress toward multipliers and added bonus. I would also take a look at the inlane switch on the right and see if it’s clipped. If not, you may be able to baby flip the ball (from a cradle) backwards up the inlane and advance your bonus to max. If that doesn’t work, Shatzing the inlane can potentially be safe. I was able to do this (on the one I had) and fairly reliably re-trap up on the left flipper.
