The hidden object game Hidden Mysteries: Buckingham Palace is the latest Facebook Fan Sale Deal at Big Fish Games. The game is $4.99 (
$9.99) if you use the coupon code IPLAYGAMES at checkout. The price is good for the PC or Mac version. I’m guessing it won the fan vote because of the upcoming nuptials between Prince William and Kate Middleton.
Sale ends at 11:59PM on Sunday, 5/1.
