Redeem a FarmVille Game Card, score a free Spring Mystery Box

While Spring normally evokes the urge to be, you know, outdoors, FarmVille players will have even more reason to maintain that sunless, pasty sheen this month thanks to a new Zynga promotion. Redeem a Zynga Game Card in FarmVille from now through April 24 and you'll also receive a free Spring Mystery Box in your Gift Box. You'll also receive a free Mystery Game Dart, but what's inside the box is obviously far more important.
