It was posted a couple of months ago, so I was surprised to see no one's linked this excellent (as always) Shut Up & Sit Down review. Looks like a fun party game suitable for all sorts of groups.
You bank when you have a hoard of gems that everyone else clearly plans to steal, but not when there’s huge piles of opportunity laid out in front of you, but also not when simply defending your stash is a good move for the round, but also not when you think everyone is going to be pointing everywhere else anyway, BUT ALSO not if you’re sure that more than one player is going to point at your stash and thus leave you safe for one more round. And are you sure about that? What are you sure about in Crossing?
