Kingdom Hearts coded is a game in the Kingdom Hearts series that was released on the mobile phone as a puzzle game using 3D backgrounds. It focuses on King Mickey and Sora, depicting the events that transpired prior to the end of Kingdom Hearts II; the game is also deeply linked with Kingdom Hearts Birth by Sleep. It is because of this that the game did not release its final episode until after the release of Kingdom Hearts Birth by Sleep, so that the ending of Kingdom Hearts coded did not spoil the ending of Kingdom Hearts Birth by Sleep with their connection. The game was announced at the 2007 Tokyo Game Show, and did not conclude until early 2010. Kingdom Hearts coded was released on the Panasonic phone: the Docomo Prime Series-P-01A. The game was released in downloadable episodes.
