context: A 1991 estimate for the global board game market was over $1.2 billion. A 2001 estimate for the United States "board games and puzzle" market gave a value of under $400 million, and for United Kingdom, of about £50 million. A 2009 estimate for the Korean market was put at 800 million won, and another estimate for the American board game market for the same year was at about $800 million. A 2011 estimate for the Chinese board game market was at over 10 billion yuan (currency). (Some estimates may split board games from Collectible card game, miniature and role-playing games; for example another 2014 estimate distinguishing board games from other types of hobby games gave the estimate for the U.S. and Canada market at only $75 million, with the total size of what it defined as the hobby game market at over $700 million, with a 2015 estimate suggesting a value of almost $900 million) A 2013 estimate put the size of the German toy market at 2.7 billion euros (out of which, the board games and puzzle market is worth about 375 million euros), and Polish markets, at 2 billion and 280 million złoty, respectively. Per capita, in 2009 Germany was considered to be the best market, with the highest number of games sold per individual.
