MySims Kingdom is an adventure game which begins with your character living in a run-down town where the king is desperate for help. The kingdom's Wandoliers, which kept the kingdom in order, have all left or retired. It is up to you, the player, to rebuild buildings and structures all throughout the kingdom using scrolls that the characters give you.
At the beginning of the game, you have the option to create and customize your own character. The player then must go to different islands and restore the buildings and structures there using essences. Each island has a different theme, and different tasks to accomplish.
Once you finish a task, you earn King Points, which helps you unlock more islands. Once you reach King Points Level 5, you unlock Reward Island, where you can build as you please.
