Candy Crush Saga is a free-to-play mobile match-three puzzle video game released by King on April 12, 2012, for Facebook; other versions for iOS, Android, Windows Phone, and Windows 10 followed. It is a variation on their browser game Candy Crush.
In the game, players complete levels by swapping colored pieces of candy on a game board to make a match of three or more of the same color, eliminating those candies from the board and replaced with new ones, which could potentially create further matches. Matches of four or more candies create unique candies that act as power-ups with larger board-clearing abilities. Boards have various goals that must be completed within a fixed number of moves or limited amount of time, such as a certain score or collecting a specific number of a type of candy.
