It's because you're using the template Infobox Mystery Game. Since it's technically one of several "Mystery" type games that you can play via the Carnival Booth, you may just want to add the category "Pig-O Game" or "Mystery Dart" to whichever sub-game when you use that template for the infobox. Your other option is to use a different infobox template.
