the one after you knock down the ball. By the way, where that ball ends up is totally counter-intuitive. It looks like it should drop down into the well, and the way it caroms off of B makes it look like he wasn't in the right place, or didn't have his legs stretched. I was shocked when I saw on the video that that was the right spot.

Nor visible, yet you criticize hidden elements.

@Don G Rowe - Come on - there's a big difference between hidden and not seeing something.

It's not that I didn't see it, It's that what I saw was, apparently, intentionally deceptive. Making it no different from hidden or a red herring.

@Don G Rowe - I'll give you the red herring one as the hole was put there for that reason but upon looking at the pathway, the ball in that hole had no benefit.

Excellent logic level! Thanks for sharing!
