Luckily, Zynga wants to help you out there, as its launched a new cross-promotional activity under the game's flash window, offering four free Crowns for completing an activity sponsored by MasterCard. This is a similar setup to those free Farm Cash giveaways in FarmVille, and this will likely just be the first of many. For this particular promotion, you'll need to complete a survey about Black Friday deals - yes, it's a bit late topically, but you can't argue with free Crowns. Unfortunately, there's no text confirmation in this activity window that you've actually earned your Crowns, but once you finish the survey questions and see a blue and white "X" appear, you can (fairly) confidently close this window. You'll likely need to refresh your game in order to see your new Crowns in your account, but they should be there safe and sound when you return.
What will you spend them on? Save them or spend them right away - that's totally up to you, but just remember to keep checking underneath the CastleVille gameplay area for additional chances at free Crowns. You never know when they might launch.
Did you complete this MasterCard promotion for four free Crowns in your game? Will you spend them instantly, or will you save them for later use? Sound off in the comments.
