Candy Crush Saga has 800 levels in Reality and 515 levels in Dreamworld, giving a total of 1,315 levels. All these levels grouped into episodes. Each episode has a different story, mascot, and name. The episode name has 1, 2, or 3 words. Most episodes have the same initial consonant sounds. There are currently a total of 54 episodes (nine worlds: 6 episodes in each) in Reality and 35 episodes in Dreamworld (five worlds: 6 episodes in each and World 6 with 5 episodes), with more episodes to come.
The first two episodes contain 10 levels, the rest contain 15. At the end of each episode (starting with Candy Factory on Facebook, or Lemonade Lake on iOS and Android), to cross over to the next episode, you have to get three of your Facebook friends to give you a ticket to cross, or buy 3 gold bars (1 gold bar for each ticket). On Android or iOS, you can complete mystery quests (including three daily quests) to cross to the next episode if not synced with a Facebook account.
Each episode has its own mascot and special logo, too. The mascot is usually a person or an animal, or other things such as a robot, a vampire and even a fairy. The logo is usually the episode's name in bolded words with a background striped banner to match the episode's area.
On November 27, 2013, Dreamworld was released, with whole new episodes and levels. Each episode imitates an episode in Reality, but usually in a slightly difficult manner. There are some exceptions though, e.g. Dreamworld level 30. To get to Dreamworld, you have to click on an owl named Odus on the map screen. Click on Odus again to return to Reality.
