As of March 2013, Candy Crush Saga surpassed FarmVille 2 as the most popular game on Facebook, with 46 million average monthly users. According to Business Insider, it is also the most downloaded iOS app for 2013. It is a variation on their browser game Candy Crush. A major expansion to the game called "Dreamworld" was launched in December 2013.
The game is periodically updated, adding new "episodes" and playable levels; new levels are updated first on Facebook followed by Android and iPhone. Candy Crush Saga has "episodes" of 15 levels each (the first two "episodes" have only 10 levels). An update to the game in December 2013 added the "Dreamworld" levels, giving players the opportunity to replay older levels with a new mechanic, which is also periodically updated. As of August 2014 via Facebook, there are 665 regular levels and 395 levels on Dreamworld.
