Players roam the Avatar Kingdom by controlling their own customized avatar which can be personalized through various means and items. These include outfits, weapons, and items which are purchasable in the game's online store using munny, which is the game's virtual currency. Avatars are used to play mini-games, meet up and chat with friends as well as do activities together within the Avatar Kingdom. Outfits as well as backgrounds can be earned by players whenever they complete an episode of Kingdom Hearts coded.

The areas are as follows: Event Hall which serves as the main area for people to participate together with friends in activities; Point Bank where players can keep track of their points as well as munny that they have earned; Mini-game Item Shop where avatars can by outfits based on Kingdom Hearts characters which they have earned by winning certain mini-games; Point Item Shop where players can buy different clothes for their avatars as well as customizing the avatar's facial features and hairstyles; Mini-game Shop where players can buy new mini-games; Information Center which provides help and support for players; V Net Room which is the player's own personal area where he can customize profiles, view friends and email other avatars; Point Melody Shop where players can buy ringtones based on songs from Kingdom Hearts games; Point Art Gallery where players can buy various backgrounds, wallpapers, graphics or icon based on the Kingdom Hearts series; Awards Area which is the player's own trophy room displaying the player's high scores at mini-games; Changing Area which is where the player can customize his avatars clothing and items.
