What would a winter holiday be like without games? Without gifts and surprises?
Hidden around the con are little boxes, which cannot be unwrapped but will greet you with the traditional yuletide blipping sound if you scan them with your NFC conbadge. Sometimes, if you do something extra nice, they also give you a little gift, in the form of an Achievement.
Getting Achievements can be simple, such as by scanning your card immediately after a STEW member, or a bit harder like giving a bit of holiday cheer to our beloved Blipmaster. Look inside the Yuletiding Manual for details. Much like the almonds which some Scandinavians put in their porridge around this time of year, some of the Achievements are hidden, and not printed in the Manual. It's up to you to look for and hopefully find them.
Happy holidays and best of luck!
