Chris Higgins 2011 Christmas Card official contest rules are as follows.
Please read Christmas card message (image) and follow instructions. (hint. #chxmascard is not the secret message it is only a clue.) If you do not understand what to do, then i guess you will not win. All entries must be placed on Christmas day, any other time will cause entry to be null and void. All prizes based on first come first serve basis and will be announced and administered only if a correct answer is given via @chrishig or retweet... yes it has to be done though twitter entering any other way ie direct email or facebook will result in entry being null and void.
Confused, too bad, complaining results in entry being null and void. Merry Christmas.
