Border countries must share a land or freshwater border with the subject country. Bonus answers are accepted for countries that only border the subject country by bridge or tunnel. Territories that are neither recognized by Sporcle as official countries, nor as integral parts of official countries, are also accepted as bonus answers. Abbreviate with Confidence™ Multi-Word Abbreviations (see comments) and all common Sporcle country abbreviations are accepted (see http://www.sporcle.com/games/tahitiwahini/common_country_name_alternatives). Data comes from the CIA World Factbook (https://www.cia.gov/library/publications/the-world-factbook/).
