RE: vince comments on bounce
Yes the bounce is not completely satifactory, specially seen at the top pin and some first bounces are off. I am droppingf balls with slight angle which should reduce decisions at pin tops. Honestly I was happy to tweak it enough for the extreme slots to have some change of a ball passing through.

@PhilOfPerth game? this strikes me more as one of those screen savers that's hard to stop watching. Something about watching that ball make it's way down the board, you never can tell where it's going to end up.

I saw vince version of Plinko and realized I was almost there with it!

Yes, that Christmas one is niice for a screen-saver. I thought the randomness was a bit off on the first run - it tended to favour the left side - but other runs proved me wrong. Nice one!
