Fun game! But it looks like matching has a bug:

The question was "Name something that's expensive when travelling" in the most common answer category.

I wrote "tickets", meaning plane tickets, and it categorized my answer as "Entrance fees (you)" instead of the top answer of "Plane ticket".

That makes sense to me; people commonly buy tickets for local events while on vacation. Perhaps it should detect and warn about that kind of ambiguity, though.
