WonderKing is a MMORPG which centers on venturing into dungeons and combatting monsters in real-time. The players combat monsters and complete quests, in the process acquiring in-game currency called "Zed", experience points (EXP), and various items. Players can kill monsters alone, or they can form a party with up to five total characters. Loot is shared based on relative damage and level of characters in the party, more being awarded to the higher-level members.
WonderKing uses a 2D scrolling viewpoint similar to a platform game. The controls for the game are executed using the keyboard and mouse. The keyboard is used for many game functions, and much of it can be rearranged to suit users' needs. The mouse is mainly used to trigger non-player characters (NPCs) and manipulate items.
WonderKing characters exist in "servers." Players are allowed to create up to 3 characters in each server. Each server, similar in content between each other in the same version, is split into at most fifteen channels, among which characters are allowed to freely switch. Currently there is no way of transferring characters between servers.
