Kingdom Hearts Mobile
Kingdom Hearts Mobile is a service released in Japan for the Docomo Prime Series-P-01A cell phones. It does not contain any developments to the overall story of the Kingdom Hearts series, but instead is a portal where people can play minigames or download ringtones, wallpapers, and other things related to the Kingdom Hearts series. It was previously available on its official website, but as of April 20, 2013, it is no longer in service.
Players can browse through an area called the "Avatar Kingdom" and visit different areas to explore. While they are in the Avatar Kingdom, they must have a controllable Avatar. Avatars can be made and customized to each individual's preference. There are outfits, weapons, items and other things that you can buy for your avatars. These avatars also exist in Kingdom Hearts Re:coded. In the service, Avatars can also meet up with friends and do activities together or play minigames.
There are many separate areas in the "Avatar Kingdom". Here are all of these areas so far. 
There is another area that is still under construction.
