Unlike the daily missions on the To-Do List which you will find faily simple to complete the quests will require more work as they primarily focus on completing chapters of a certain story or a doing a specific type of task. New quests open up as soon as you complete one, they are only available within a certain period of time, and you can always continue your progress in the quest as long as it is active, unlike with the To-Do List that refresh the list of tasks every day. Each quest is divided into different stages and each stage has 3 tasks and hints. Like the To-Do List you will be rewarded well in the form of SimCash and Simoleons when you complete quests.
