Bubble Witch Saga introduced the "saga" approach in contrast to typical tile-matching games, where instead of having the game continue through a fixed amount of time or until the player reached an unplayable state, the game was divided into discrete levels that required the player to complete certain goals within a fixed set of moves, and where the next level could only be reached after completing the previous level. King's first major success in this area followed with Bubble Witch Saga, released in October 2011 by January 2012 it has attracted over 10 million players and was one of fastest rising Facebook games at that time. In April 2011, King released its existing portal game Miner Speed as its first cross-platform (Facebook and mobile) game to figure out the transition between Facebook and mobile games for this new direction.
