I did click on the card the second time (prompted by the movement), but I didn't really understand that it was necessary.
It didn't occur to me that I would need to click again to "take" the reward, because I don't see a reason that I *wouldn't* collect the reward, if that makes sense.
To put it another way, if there were times that I didn't want the displayed card (rewards that were somehow "bad" for me), then the click would make sense, but if it's always something I want (or nothing), then the second click feels like an odd requirement to me.
Not a problem, exactly, but I do think it's a little confusing because there's no clear reason for the second click.
That said, many thanks for the free stuff.
