Nintendo Badge Arcade

Nintendo Badge Arcade is a free-to-play puzzle game developed and published by Nintendo in Japan on December 17, 2014 and in the rest of the world in November, for Nintendo 3DS. The game allows to win badges to decorate the console's home menu, by playing for free or by paying. The available badges are over 3000, and the game has to always be online to work. A workaround to unlock all the badges has been found, but since the paid service is still active, it is posted here only for documentation purposes. As long as the service is available, please use it following the official way.
