Yes I thought this at first, but there is a kind of bug on the engine and the behaviour is not homogenous right now. Because if you hit the hole on a vertex, you fall int the hole. If you hit the hole on a corner you rebound. This is too strange to be kept like this.
I don't think he should change it because the way an actual pool game is, if you get the cue ball in (the white ball), you scratch. But, of course you're the boss so my opinion doesn't matter.
